Hi there. This is Harry. And welcome back  to advanced English Lessons with Harry,

where I try to help you to get a better  understanding of the English language.
1
4320
4000
00:08
And in this particular  lesson we're going to look at
2
8320
2960
00:11
conditional tenses okay.
3
11280
1520
00:12
And just a little bit of a comment on them
4
12800
2480
00:15
first of all. Conditional clauses usually  consist of two parts. You'll have the what  
5
15280
6240
00:21
I call the if clause or what the grammar books  call the hypothesis. It's a difficult word to  
6
21520
7200
00:28
pronounce. And then we have the main  clause, which is the result. Okay. So
7
28720
6080
00:34
if clause can be first or second, it doesn't  really matter. And the main clause can be first.
8
34800
5840
00:40
The second as long as you  keep them separate. Okay. So
9
40640
3920
00:44
If clause, and then the main clause  on main clause and then the if clause.
10
44560
5600
00:50
Okay. Let's start with the  zero conditional. And the  
11
50160
3600
00:53
structure of the zero conditional  is that we use it to talk about.
12
53760
3760
00:57
Something that's always true, or something about  the laws of nature. Let me give you some examples.  
13
57520
6720
01:04
If you heat ice, it melts. Simple fact. If you  heat ice, it turns to water. It melts. If you  
14
64240
9360
01:13
study hard, generally you pass exams. If you press  the button, the machine stops or indeed starts,  
15
73600
9280
01:22
depending on which button you press. And  if you mix black and white, you get grey.
16
82880
6320
01:29
The colour grey. Okay, so they're statements,  truisms or facts or something about the  
17
89200
7440
01:36
laws of nature. And that's really  how we use that zero conditional.
18
96640
4720
01:41
And we can also use when here instead of if, for  example, when you tickle a baby, he or she laughs.
19
101360
10000
01:51
It's easier to sleep when you are not stressed.  When babies are hungry, they cry. You know,  
20
111360
7920
01:59
all of us who are parents will know all  about that one. When babies are hungry,  
21
119280
5440
02:04
they cry. Generally. Okay,  so again zero conditional.
22
124720
4560
02:09
Now we can replace if with on less.  Usually in a negative situation. Do  
23
129280
7200
02:16
your homework. Unless the teacher tells  you not to do your homework. Unless the  
24
136480
6000
02:22
teacher tells you not to. So all  good examples. Zero conditional.
25
142480
6400
02:28
So let's look at the first conditional  okay. So this is when it gets a little  
26
148880
4240
02:33
bit more complicated okay. So when  we use the first conditional we are  
27
153120
5360
02:38
talking about if plus the present okay  okay. Or if plus present continuous.
28
158480
7120
02:45
present perfect. And then we have the  second clause, the main clause with
29
165600
6240
02:51
The future imperative. And then we can  use can must, should. And it's with the  
30
171840
5920
02:57
bare infinitive. So that all sounds like a  mouthful. So let me give you some examples.
31
177760
5360
03:03
We use first conditional to talk about something  real likely to happen in the immediate,  
32
183120
7760
03:10
or in the present time, or in  the immediate future. Okay. So.
33
190880
4000
03:14
If it rains, we will go to  the cinema. If it rains,  
34
194880
3920
03:18
we will go to the cinema. So if it rains,  if plus present simple, if it rains, then
35
198800
7280
03:26
We will go to the cinema. So we've  got that there infinitive. We will  
36
206080
6560
03:32
go to the cinema. Okay. So if it  rains we will go to the cinema.
37
212640
4640
03:37
If it doesn't rain, we will go  for a walk. If it doesn't rain,  
38
217280
4480
03:41
we will go for a walk.  Exactly the same. But it's the
39
221760
3600
03:45
if clause separate from the will clause and you  can turn it around, as I said before. So you can  
40
225360
5520
03:50
say we will go to the cinema. If it rains,  we will go to the park if it doesn't rain.
41
230880
7040
03:57
So
42
237920
640
03:58
one clause first, the main clause with will  and then the if clause second, or if clause  
43
238560
6160
04:04
first. If it rains, we will go to the cinema. So  you have a choice to reverse some if you wish.
44
244720
6400
04:11
If he doesn't study, he will fail his exams.  If he doesn't study, he will fail his exams.
45
251120
6880
04:18
If you need money, let me know. If you  have cleaned your room, you can watch TV  
46
258000
9200
04:27
and if you're in town, you should call us or you  should call me. Okay, so there are examples of  
47
267920
7280
04:35
using if with different tenses. And then in that  second of the main clause, we've got that future
48
275200
8000
04:43
And we can use can or may or might or  must or should with the bare infinitive.
49
283200
5680
04:48
Never put if and will in the  same clause. That's a real no no.
50
288880
5680
04:54
So if it's sunny, we will go to the beach.  If it's sunny. That's your if clause. If it's  
51
294560
6160
05:00
sunny and your main clause, we will go to the  beach. Not if it will be sunny. We will go to  
52
300720
6640
05:07
the beach. You see that often. And it's a it is a  mistake. So if it's usually followed by one of the  
53
307360
5600
05:12
present tenses in this first conditional, if it  rains, we will, we will or we'll go to the beach.
54
312960
7520
05:20
So try and keep them separate. And it's always  a good way to check yourself. If you see that  
55
320480
4960
05:25
you've got if and will in the same clause, then  you're wrong. Okay. So you can't. And it's not  
56
325440
6000
05:31
good idea to have will two clauses. That's  another indication that you've done something  
57
331440
4480
05:35
wrong. So look for your two clauses. If it rains  one clause we will go to the beach main clause.
58
335920
7760
05:43
So make sure you have will  only in one of those clauses.
59
343680
4080
05:47
Now we can also substitute if for some other words  
60
347760
3920
05:51
like provided or providing.  So long as or as long as,
61
351680
6560
05:58
or on condition that. Let  me give you some examples.
62
358240
4240
06:02
I will cook dinner provided your home on time.
63
362480
4000
06:06
I will cook to dinner as  long as you’re home on time.
64
366480
4320
06:10
I will cook dinner only if you're home on time.
65
370800
3440
06:14
I will cook dinner on condition  that you are home on time. Okay,  
66
374800
4560
06:19
so I'm using the same sentence just to  emphasise the point that we can substitute
67
379360
5440
06:24
if with a number of other words, but  we're still using the conditional tenses.
68
384800
5360
06:30
Now let me give you another example. When we want  to be really emphatic. Yeah. My teacher thinks  
69
390160
5920
06:36
I will pass the exam. My teacher thinks I will  pass the exam provided I continue to work hard.
70
396080
7440
06:43
I will lend you my book, or  I will lend you the book,  
71
403520
4640
06:48
as long as you promise to give it back to me.
72
408160
3760
06:51
I'll tell you what really happened. Only  if you can keep a secret. So they're good  
73
411920
5760
06:57
examples of those first conditionals  where we're emphasising a point,  
74
417680
5520
07:03
and we want to use some words to  be a little bit more emphatic.
75
423200
4400
07:07
Now we can also use even if. Okay. And  this is used when we want to express a  
76
427600
5280
07:12
condition that is somewhat unexpected  in certain circumstances. For example,  
77
432880
6160
07:19
even if you apologise, she will never forgive you.  Even if you apologise, she'll never forgive you.
78
439040
7040
07:26
We can also use it to express alternative  conditions. I'll go to the concert whether  
79
446080
7040
07:33
you like it or not. I'll go to the  party whether you like it or not.
80
453120
5760
07:38
And we can also then use it  when we're talking about,
81
458880
3040
07:41
situations like... well, I’d say a fire.
82
461920
2880
07:44
We use it with a noun in case of fire.  Do not use the elevator in case of fire.
83
464800
7520
07:52
Do not use the elevator. In case of an emergency.  Call 999. In case of an emergency. Call 999. Okay,
84
472320
11040
08:03
so that's all about those first  conditional tenses. And where  
85
483360
4160
08:07
we can substitute if for other  words like provided as long as.
86
487520
4560
08:12

88
497280
4240
08:21
So let's look at the second conditional. Now when  we're talking about the second conditional just a  
89
501520
5840
08:27
little hint here. We're talking about the unreal  future okay. So it's unlikely to happen in the  
90
507360
6480
08:33
future. But we use the past tense to describe.  It's a little bit confusing. So when you see  
91
513840
6560
08:40
the past tense it's not actually talking about  the past, it's referring to an unreal event.
92
520400
6480
08:46
In the future. Okay. So it's. If so, we  always have if if plus the past simple  
93
526880
6560
08:53
or the past continuous. And then we use would  could might plus that bare infinitive okay. So.
94
533440
8560
09:02
If you see well, it's not the second conditional.  If you use will. You're making a mistake.
95
542000
6080
09:08
So we use the second condition, as I  said, to talk about imaginary situations.
96
548080
5680
09:13
Contrary to the present or the facts about  the present for example, if I were taller,  
97
553760
6720
09:20
I would be a basketball player. I'm  obviously not going to be any taller.  
98
560480
4480
09:24
I'm obviously not going to be a basketball  player. I'm we're talking about the future.  
99
564960
4080
09:29
If I were taller, I would be a basketball player.
100
569040
2880
09:31
But we're using that past
101
571920
2720
09:34
simple to describe it. If I were  taller. And another issue about this  
102
574640
5040
09:39
second conditional we usually say were  instead of was if not if I was taller,  
103
579680
6000
09:45
if I were taller, I would be a basketball player.
104
585680
6560
09:52
If I won the lotto, I would quit  my job and travel the world.
105
592240
5520
09:57
I would visit Paris every week.
106
597760
2960
10:00
If I had lots of money. Okay, so these are all  unreal situation. Now there is a possibility  
107
600720
6080
10:06
that at one stage they might just might happen,  but at the moment they're not likely to happen.  
108
606800
6080
10:12
So we're using the second conditional to  describe them. We're using the past simple  
109
612880
4640
10:17
or past continuous. And then it's followed in  the main clause with would or could or might.
110
617520
6560
10:24
Also, if we're giving advice, we also use that  second conditional and it starts as follows.  
111
624080
8080
10:32
If I were you, I would do something. If I were  you, I would go to the doctor about that cough.
112
632160
6960
10:39
If I were you, I would call him  and find out what's happening.
113
639120
3840
10:42
If I were you, I would take a taxi  because the buses are on strike.
114
642960
5120
10:48
Okay. So again,
115
648080
1360
10:49
giving advice to people. If I and we started  if I were you again the use of that past tense.  
116
649440
7360
10:56
But we're talking about future events. If I  were you. Because you're not going to be. I  
117
656800
4880
11:01
would take a taxi. If I were you, I would call  him. If I were you, I would go to the doctor.
118
661680
8160
11:09
Most people use that word. Some people tried t to  
119
669840
3920
11:13
use was. And this is again the  difference when we talk about
120
673760
4400
11:18
British English and American English. Okay.  But the grammar books will tell you and it's,  
121
678160
6080
11:24
it's better to use were in that situation only  in a situation when using the second conditional.
122
684240
7920
11:32
now let me give you some more examples. I  would be grateful if you could deal with  
123
692160
5440
11:37
this matter yourself. I would be grateful if  you could deal with this matter yourself. We  
124
697600
6480
11:44
would appreciate it if you could sign this  form and send it back. I would be grateful
125
704080
7440
11:51
if you could give me a discount.  Okay, so these are situations where  
126
711520
3760
11:55
we're making polite requests for  something and we're using that.
127
715280
4640
11:59
Second conditional.
128
719920
2080
12:02
If we want to give an excuse or excuses,  we can also use second conditional. If  
129
722000
6400
12:08
there were more hours in the day,  I would gladly help you with this.
130
728400
5280
12:13
If my help were outside, my health and my  health were better, I would spend more time  
131
733680
6240
12:19
exercising if my health were better.  I would spend more time exercising. So
132
739920
5840
12:25
again. The talking about,
133
745760
1680
12:27
the future again. We're talking about
134
747440
2880
12:30
using the past to describe it. And again, we're  talking about unreal situations. At that time,  
135
750320
6560
12:36
if my health were better, it's  not. So I can do nothing about it.
136
756880
4080
12:40
If there were more hours in the day, I would  help you. There are no more hours in the day,  
137
760960
4240
12:45
so I can't help you. That's realistically  what it means. So these are unreal situations
138
765200
7200
12:52
And we don't use them unless with these.
139
772400
2240
12:54
unreal
140
774640
880
12:55
conditions or situations.  We only use if and again,  
141
775520
4800
13:00
the same as we had with the first conditional.
142
780320
2960
13:03
Make sure that if and would or if  and could are in separate clauses.  
143
783280
6320
13:09
If in the first clause could  or would in the main clause,  
144
789600
4880
13:14
and again switch them around if you wish to do so.  But just make sure you keep them separate. Okay,
145
794480
6720
13:21
And now we're going to look at the  third conditional. We've looked at  
146
801200
4240
13:25
zero and first conditional. And second  conditional. And now we're going to  
147
805440
4560
13:30
look at the third conditional. Third  conditional. A little bit more tricky.  
148
810000
4480
13:34
Okay. The good news here is we're  talking about the past. All right.
149
814480
4080
13:38
But we're talking about something that  has happened or didn't happen. And it's  
150
818560
5680
13:44
impossible to change it at this stage  okay. So always is. But something that  
151
824240
4320
13:48
has happened in the past or didn't happen  in the past, and you cannot change it.
152
828560
7200
13:55
So we use if together with the past. Perfect.  If I had done something. Okay. And then in  
153
835760
8080
14:03
the main clause of the second clause we  use word or code or might with the have
154
843840
7440
14:11
And the past participle. Okay, so  let me give you an example of that.
155
851280
4800
14:16
So we're using the third conditional to imagine  situations or actions in the past that we know  
156
856080
8080
14:24
are the opposite of the facts. As they are. For  example, they would have heard the news if they  
157
864160
6960
14:31
had listened to the radio. Well, they weren't  listening to the radio. We'd know they weren't,  
158
871120
4480
14:35
but if they had, listen to the radio,  they would have heard the news.
159
875600
4560
14:40
And here in this example, we're  turning them around again,  
160
880160
2720
14:42
as we've done with all the conditions, it  doesn't matter which clause you put first,  
161
882880
4160
14:47
as long as you keep that if and would or  if and will separate. So here they would  
162
887040
4480
14:51
have heard the news. So here they  would have heard. So that's your
163
891520
4160
14:55
have plus your,
164
895680
1120
14:56
past participle, they would have heard the news.
165
896800
3040
14:59
And then if they had listened to the  radio. And that's our past perfect.
166
899840
6720
15:06
Another example. If you had left ten minutes  earlier. So here we've got if in the first clause,  
167
906560
5840
15:12
if you had left ten minutes earlier,  you wouldn't have missed the train.  
168
912400
5920
15:18
So he didn't leave ten minutes earlier and  he did miss the train. So if you had left,  
169
918320
5840
15:24
if with that past perfect, if you had left  ten minutes earlier, you wouldn't have missed.
170
924160
6160
15:30
And here we have, would or wouldn't  in this case, plus have plus the past  
171
930320
5360
15:35
participle missed the train. Okay, so we  know he didn't leave ten minutes earlier,  
172
935680
6160
15:41
and therefore we know that he did miss the train.
173
941840
4240
15:46
So just a rule here. If the  past condition happened,  
174
946080
4480
15:50
we use a negative. If it didn't happen we use  a positive. Okay. If I hadn't got the job.
175
950560
9760
16:00
I might have stayed in Glasgow. If I hadn't  got the job, I might have stayed in Glasgow.  
176
960320
6160
16:06
The fact is, on the condition, as it happened,  I did get the job so I didn't stay in Glasgow.  
177
966480
6960
16:13
If I had got the job I couldn't  have stayed in Glasgow. So.
178
973440
4800
16:18
that means I didn't get the job and  therefore I did stay in Glasgow.
179
978240
4000
16:22
So
180
982240
320
16:22
If the the past condition  happened. You use a negative verb.
181
982560
5760
16:28
And if it didn't happen, then the  opposite. We use a positive, vice versa.
182
988320
5840
16:34
Now there is a way of writing this third  conditional, which is often used in books,  
183
994160
5680
16:39
and they're often used as a more literary  style. Okay, so had the film been released  
184
999840
8400
16:48
after the pandemic, it might have been more  successful. So it's here, we're saying had  
185
1008240
5120
16:53
had the film. It just means if the film had  been released the other way to write it.
186
1013360
5680
16:59
But in literary terms, it can often  look more attractive if we write it  
187
1019040
4240
17:03
and say it this way. Had the film  been released after the pandemic,  
188
1023280
6320
17:09
it might have been more successful if the  film had been released after the pandemic,  
189
1029600
6800
17:16
it might have been more successful. We  usually don't use it in the speaking,
190
1036400
4880
17:21
way because it's more of a literary  art as more for for writing.
191
1041280
4960
17:26
Now.
192
1046240
400
17:26
got one more part of the conditionals to look  at. And these are mixed conditionals. Now these  
193
1046640
5280
17:31
are not used so often. And they're really  at that upper intermediate and beyond. So  
194
1051920
5200
17:37
don't worry if you don't understand them  or you don't get to use them in fact,  
195
1057120
3760
17:40
you might not even see them  as so often, but they can be,
196
1060880
3600
17:44
Used in exams at C1, C2 level in particular,  
197
1064480
4320
17:48
but you don't often hear them. But let me  give them to you anyway. And then you can  
198
1068800
3760
17:52
at least you know you've you've read them. But  focus more on the zero first, second and third.
199
1072560
7200
17:59
So these are less common patterns when we  talk about conditional tenses. And as I said,  
200
1079760
6000
18:05
we call them mixed conditionals.  And they can be mixed in different  
201
1085760
3200
18:08
ways. So the first one would be  mixing the past to the present  
202
1088960
4000
18:12
conditional. Okay. So we've got if plus  past perfect and then a result which is  
203
1092960
7600
18:20
would plus the infinitive. If I had learnt to  play the violin I could give music lessons.
204
1100560
8480
18:29
Now if I had learnt to play the violin I  could give music lessons. Now the fact is,  
205
1109040
8400
18:37
I didn't learn how to play the violin and  therefore I cannot give music lessons now.  
206
1117440
6880
18:44
But if I had learnt to play the violin,  so that's if plus are past perfect,  
207
1124320
5920
18:50
I could give music lessons now and  that's mixing it to a present condition.
208
1130240
6080
18:56
Okay.
209
1136320
1440
18:57
Or if we had missed the bus, we wouldn't be  here to celebrate Christmas. The fact is,  
210
1137760
6800
19:04
we didn't miss the bus. And yet, here we are  on your doorstep and enjoying and visiting for  
211
1144560
5760
19:10
Christmas. Okay, so if we had missed the bus,  we wouldn't be here to celebrate Christmas.
212
1150320
7280
19:17
And then the second one is to mix the present to  
213
1157600
2720
19:20
the past conditional. So the  the reverse. And it's the.
214
1160320
3440
19:23
if plus past simple and then the result  could or would with the have and the past  
215
1163760
8000
19:31
participle. If we knew more about the software  now, if we knew more about the software now,  
216
1171760
6400
19:38
we wouldn't have had to call the help  line if we knew more about the software.
217
1178160
6160
19:44
So if plus the past simple, if we knew  more about the software, we wouldn't have  
218
1184320
5680
19:50
had that's a have plus up past participle. We  wouldn't have had to call the help line. Okay,  
219
1190000
6720
19:56
now the fact is we didn't know. So  we we we had to we had no choice.  
220
1196720
5120
20:01
You could have gone to study computer  science if you were better at maths.
221
1201840
4960
20:06
So again, if you were better at maths,  
222
1206800
2080
20:08
you could have gone to study computer  science. Fact is you weren't okay.
223
1208880
4720
20:13
And then the third one is to mix past to future  conditional. Okay, so it's the if plus past  
224
1213600
8160
20:21
simple. And then a future result usually using  will. So for example if they left at midday on  
225
1221760
7600
20:29
Monday they will be here by lunchtime tomorrow.  So here you can see where moving to the future.  
226
1229360
5840
20:35
And we're using Will. If they left at midday on  Monday they will be here by lunchtime tomorrow.
227
1235200
8400
20:43
All right. So that's the third option which is  I said the mixed past to future conditional. And  
228
1243600
6080
20:49
then one last one when we have the mixed past to  the past or the present conditional. For example,  
229
1249680
7920
20:57
if you gave him all your money, you've  made a big mistake. If you gave him all  
230
1257600
4960
21:02
your all your money, you've made a big  mistake because he's probably spent it.
231
1262560
4640
21:07
If you gave him all your money, you've made  a big mistake. It's if plus that past simple.  
232
1267200
5520
21:12
If you gave him all your money, you've made  it says your present perfect. A big mistake.
233
1272720
5920
21:18
Okay, so that's all of those conditional zero  first, second, third. And then just as we've  
234
1278640
7760
21:26
covered now. Mixed conditionals I'll say just  I'll just highlight again with the mix conditions.
235
1286400
5120
21:31
You're not going to see them so often if you're at  sort of intermediate or upper intermediate you'll  
236
1291520
6880
21:38
see them when you get beyond that to advanced  levels. You need to know them and understand them,  
237
1298400
5200
21:43
but you recognise them when you see them. There'll  be a bit unusual. They're not the same as any of  
238
1303600
4400
21:48
the other conditionals. But don't worry if you  don't understand them fully, check it out in a
239
1308000
4800
21:52
grammar book. Check it out on my course. Okay,  
240
1312800
2800
21:55
thanks for listening to this particular  lesson. Join me for the next one.
