Let's talk about present perfect tense.

First question!
7
26880
1000
00:27
This question comes from Zara.
8
27880
1180
00:29
“Hi, Alisha!
9
29060
1000
00:30
I have a question about present perfect tense.
10
30060
2690
00:32
In my native language, there isn't a tense called present perfect tense.
11
32750
3700
00:36
I am confused because I don't know the differences between present perfect tense and simple past
12
36450
6120
00:42
tense well.”
13
42570
1000
00:43
Let's begin with an in-depth explanation of these two grammar points and the differences
14
43570
4460
00:48
between them.
15
48030
1000
00:49
Okay.
16
49030
1000
00:50
To begin.
17
50030
1000
00:51
Let's begin with a simple timeline here.
18
51030
1000
00:52
We have the past, now, which is the star on the timeline, and the future.
19
52030
4490
00:56
So, we're going to focus on the “past” and the “now” points.
20
56520
3890
01:00
Let's focus on those.
21
60410
1359
01:01
First, let's look at the simple past tense.
22
61769
2981
01:04
We use the simple past tense for actions which started and ended in the past.
23
64750
4890
01:09
So, at a point in time before the present.
24
69640
2890
01:12
A point in time before now, in other words.
25
72530
2670
01:15
On our timeline then, let's imagine there are two points, a start point and an end point
26
75200
4980
01:20
for that action.
27
80180
1030
01:21
Okay.
28
81210
1000
01:22
Here, I've made a start point and an endpoint on the timeline.
29
82210
3100
01:25
So, in the past, you can see there are two points, the start and the end of the action.
30
85310
5860
01:31
Both are in the past.
31
91170
1130
01:32
You'll see both of them are in the past.
32
92300
2010
01:34
That's the first point about the simple past tense.
33
94310
2770
01:37
Also, these are for actions that we did at a specific point in time.
34
97080
4710
01:41
We can assign a specific point in time to these actions.
35
101790
3790
01:45
For example, this morning, last year, last week, yesterday.
36
105580
4540
01:50
There's a specific point in time we can attach to these actions.
37
110120
3720
01:53
Okay.
38
113840
1000
01:54
Let's talk now about the present perfect tense.
39
114840
2390
01:57
Present perfect tense has a couple of different uses.
40
117230
2520
01:59
The first use of present perfect tense I want to explain is using the grammar point to explain
41
119750
5360
02:05
a life experience.
42
125110
1730
02:06
Let's take a look at how visually this is different from the simple past tense.
43
126840
4020
02:10
So, now on the timeline in blue, you can see this sort of dotted line that I made with
44
130860
5320
02:16
a question mark.
45
136180
1540
02:17
The dotted line begins in the past and it ends now.
46
137720
3640
02:21
It ends at the current point in time.
47
141360
2560
02:23
This is because we use present perfect tense to talk about things that happened at some
48
143920
5640
02:29
point in the past but the specific point is unimportant or unknown.
49
149560
7030
02:36
We don't need to explain when the action happened.
50
156590
4040
02:40
We only want to state we have had or have not had that experience.
51
160630
5570
02:46
So, we use this when we want to talk about our life experiences.
52
166200
4260
02:50
For example, travel experience or work experience like “I have never been to France.”
53
170460
4860
02:55
or “I've eaten pho.”
54
175320
1350
02:56
“My parents have never been outside the country.”
55
176670
2200
02:58
for example.
56
178870
1220
03:00
We use this to talk about life experience but we don't include a specific point in time
57
180090
5780
03:05
when we talk about these experiences.
58
185870
2590
03:08
It's just some time before the present.
59
188460
2570
03:11
The specific point in time is not important in that sentence.
60
191030
3950
03:14
You might follow up this sentence with a specific point in time, in which case, you use simple
61
194980
5110
03:20
past.
62
200090
1320
03:21
Let's talk about one more use of the present perfect tense.
63
201410
3340
03:24
This is the one we use with the words “for” and “since” and we can also use the continuous
64
204750
5569
03:30
tense with this use.
65
210319
1471
03:31
The black line on the timeline here shows an action that started in the past and continues
66
211790
5180
03:36
to the present, or it's an effect of an action that continues to the present.
67
216970
6310
03:43
We use this to talk about our studies, for example, or the places where we live.
68
223280
4360
03:47
Like, “I have been studying English for three years.”
69
227640
3020
03:50
or “I have lived in Brazil for 10 years.”
70
230660
3110
03:53
for example.
71
233770
1000
03:54
So, remember that we use the words “for” and “since” along with this form of the
72
234770
3960
03:58
present perfect tense.
73
238730
1339
04:00
We use “for” before a length of time like, “I've studied for three years.”
74
240069
4601
04:04
“I've lived in Brazil for five years.”
75
244670
2300
04:06
and we use “since” before a period of time.
76
246970
4010
04:10
I have lived-- “I've been studying since 2009.” or “I have lived here since 2013.”
77
250980
6439
04:17
for example.
78
257419
1000
04:18
So, please keep this in mind, the present perfect tense is used for actions that started
79
258419
4901
04:23
in the past and continue to the present.
80
263320
2740
04:26
Simple past tense is used for actions which started and ended in the past.
81
266060
4190
04:30
Next question.
82
270250
1000
04:31
This question comes from Maxine.
83
271250
1000
04:32
Hi, Maxine!
84
272250
1000
04:33
“What's the difference between “one year” and “a year?”
85
273250
2840
04:36
For example, “I've lived here for a year.”
86
276090
2350
04:38
or “I've lived here for one year.”
87
278440
2170
04:40
In this sentence, no difference.
88
280610
1640
04:42
Honestly.
89
282250
1000
04:43
When you're talking about time periods, “a year,” and “one year,” “a minute,”
90
283250
4230
04:47
“one minute.”
91
287480
1000
04:48
They don't mean anything different.
92
288480
1290
04:49
They mean the same thing.
93
289770
1290
04:51
Thanks for the question though.
94
291060
1320
04:52
Next question!
95
292380
1000
04:53
Next question comes from Wang Zhang Ik.
96
293380
2050
04:55
I’m very sorry.
97
295430
1240
04:56
“Which one is correct?
98
296670
1650
04:58
‘I work out for one to two hours a day.’
99
298320
2690
05:01
‘I work out for one or two hours a day.’
100
301010
2540
05:03
‘I drink coffee two to three times a day.’
101
303550
2650
05:06
‘I drink coffee two or three times a day.’”
102
306200
2680
05:08
Ah!
103
308880
1000
05:09
Both of these are correct, actually.
104
309880
2380
05:12
In this case, there are very, very small differences between these.
105
312260
3550
05:15
“One to two hours a day,” means “between one and two hours.”
106
315810
4680
05:20
If you say, “I work out for one or two hours a day,” it means it's determined like one
107
320490
6780
05:27
hour only for a workout or two hours only for a workout.
108
327270
3730
05:31
So, the difference here is, are you determining?
109
331000
2920
05:33
Are you deciding one hour or two cups of coffee or three cups of coffee or is it between those
110
333920
6850
05:40
two amounts?
111
340770
1000
05:41
So, using “one to two” or “two to three” means between those two amounts.
112
341770
5250
05:47
Using “or” shows it's either A or B, but not between those two.
113
347020
6100
05:53
This is the difference between “to” and “or.”
114
353120
2490
05:55
Next question!
115
355610
1210
05:56
Next question comes from Wong Sena.
116
356820
1819
05:58
I'm very sorry.
117
358639
2041
06:00
I'm very sorry.
118
360680
1310
06:01
“‘I've never been to Japan.’
119
361990
1600
06:03
‘I've never been to Japan before.’
120
363590
2100
06:05
‘I've never eaten horse.’
121
365690
1460
06:07
‘I've never eaten horse before.’
122
367150
2250
06:09
My question is, if you put ‘before’ at the end of those sentences, does it mean,
123
369400
4501
06:13
you are in Japan right now?
124
373901
1809
06:15
Or you are eating horse right now?”
125
375710
1940
06:17
No.
126
377650
1000
06:18
Not necessarily.
127
378650
1000
06:19
Think of “before” at the end of the sentence as “before now.”
128
379650
3580
06:23
“I've never eaten horse before now,” in other words.
129
383230
4130
06:27
You could use this just before you eat horse or just before you go to Japan, if you like
130
387360
6210
06:33
as an emphasis phrase, but it doesn't necessarily mean that you are in Japan now or that you're
131
393570
6460
06:40
eating horse now.
132
400030
1300
06:41
You could use it in that way, sure, but it doesn't necessarily mean it.
133
401330
4640
06:45
If you'd like to emphasize it, like if you're about to eat horse, for example, “I've never
134
405970
4180
06:50
eaten horse before.”
135
410150
1070
06:51
you could show your interest or perhaps to show, maybe some anxiety, or nervous feelings
136
411220
5640
06:56
about what you're about to do.
137
416860
2290
06:59
But, no, it does not necessarily mean you are in that place.
138
419150
4430
07:03
Like, for example, you could just be having a conversation.
139
423580
3020
07:06
“Have you eaten horse before?”
140
426600
2170
07:08
“No.
141
428770
1000
07:09
I've never eaten horse before.”
142
429770
1000
07:10
It could just be a conversation about it.
143
430770
2489
07:13
But, really, “before,” just means “before now.”
144
433259
3671
07:16
Next question!
145
436930
1239
07:18
Next question comes from Rashke.
146
438169
1691
07:19
I'm sorry.
147
439860
1270
07:21
“Where do we use ‘wanna,’ and ‘gonna,’ and how?”
148
441130
4750
07:25
Ah!
149
445880
1000
07:26
This question is about the casual contracted forms of “want to” and “going to.”
150
446880
4910
07:31
“Want to” becomes “wanna.”
151
451790
1980
07:33
“Going to” becomes “gonna” in casual speech.
152
453770
3720
07:37
We use them in exactly the same way we would use “I want to,” “I'm going to,” “he
153
457490
5470
07:42
wants to,” “she wants to,” “he's going to,” “she's going to.”
154
462960
3310
07:46
We use them in exactly the same way, which means, we use them in casual situations.
155
466270
5619
07:51
Like, “I want to take a day off,” or “I'm gonna go to the beach this weekend,” or,
156
471889
4030
07:55
“Do you want to see a movie tonight?”
157
475919
2281
07:58
We use them in exactly the same way we use “want to” and “going to” but we use
158
478200
6059
08:04
them in speech.
159
484259
1101
08:05
Typically, we don't write these.
160
485360
1860
08:07
Unless, we're writing very casual messages like text messages to our friends or something.
161
487220
4790
08:12
Next question!
162
492010

08:13
Next question comes from Garrison Silva.
163
493410
1390
08:14
Hey, again, Garrison.
164
494800
1000
08:15
“When can I use the expression, ‘take for granted?’”
165
495800
3020
08:18
“Take for granted.”
166
498820
1340
08:20
This is an expression which we typically use in the negative.
167
500160
3220
08:23
Like, “Don't take something, something for granted.”
168
503380
3080
08:26
“Don't take blah, blah, blah for granted.”
169
506460
1890
08:28
It means, don't forget to appreciate this thing or this person.
170
508350
7450
08:35
For example, “Don't take your parents for granted.”
171
515800
2299
08:38
or “Don't take this opportunity for granted.”
172
518099
2320
08:40
These expressions mean, don't forget to appreciate these things, or don't just disregard your
173
520419
5991
08:46
parents, or don't disregard this opportunity.
174
526410
2220
08:48
To recognize the importance of something.
175
528630
2340
08:50
So, if you are given a good opportunity, for example, or someone gives you good advice,
176
530970
4760
08:55
or a very nice gift, perhaps, we would typically use this with the negative.
177
535730
5030
09:00
“Don't take something, something for granted.”
178
540760
2569
09:03
meaning don't forget to show your appreciation for that thing or for that person.
179

Next question!

Next question comes from Daniel Silverio.
181
550740
2510
09:13
Hi, Daniel!
182
553250
1040
09:14
Daniel asks, “What is the difference between ‘wish’ and ‘desire?’
183
554290
4810
09:19
Greetings from Paraguay.”
184
559100
1000
09:20
Hey!
185
560100
1000
09:21
What is the difference between “wish” and “desire?”
186
561100
2529
09:23
“Wish” is used to express want.
187
563629
3820
09:27
When you want something that is different from the present situation.
188
567449
4031
09:31
So, we often use it with, “I wish I were,” or “I wish I could.”
189
571480
4919
09:36
Something we want or an ability we want, but that we do not have now.
190
576399
7000
09:43
Something for the future.
191
583399
1230
09:44
So, “I wish I could speak seven languages.”
192
584629
3020
09:47
or, “I wish I had a million dollars.”
193
587649
2401
09:50
or, “I wish I were taking more time off every week.”
194
590050
3459
09:53
for example.
195
593509
1440
09:54
Something that is different from the present condition.
196
594949
2810
09:57
The present situation we use “wish” or “I wish you would call me.” for example.
197
597759
4871
10:02
“I wish you would.”
198
602630
1000
10:03
or “I wish you could.”
199
603630
1429
10:05
To express something that is not happening now.
200
605059
3491
10:08
“Desire,” on the other hand.
201
608550
1899
10:10
“Desire” tends to be used more formally and it also can carry more romantic nuances.
202
610449
6661
10:17
It's not used as much conversationally as the word “wish” is.
203
617110
4110
10:21
“Wish” is used to express wants.
204
621220
2200
10:23
Things that we want that are not true now.
205
623420
2759
10:26
“Desire” is used more in romantic situations.
206
626179
4320
10:30
Like, to desire another person, or “He desired more of her time.”
207
630499
5080
10:35
for example.
208
635579
1331
10:36
But it sounds unnecessarily formal, I feel.
209
636910
3390
10:40
You might use it in a more formal, like a business context.
210
640300
4110
10:44
Like, “Our client desires more information about the situation.”
211
644410
5539
10:49
That could be a different use of the word “desire.”
212
649949
2560
10:52
But in general, it sounds a bit more formal and a bit more romantically charged at times,
213
652509
5411
10:57
depending on the situation when it's used.
214
657920
2490
11:00
If you're talking about a person, as well, like if you say, for example, “I desire
215
660410
4010
11:04
you.”
216
664420
1000
11:05
it sounds actually quite odd at least in American English.
217
665420
3599
11:09
If you want to use the word “desire,” I think in romantic situations, it might be
218
669019
4981
11:14
applied in a phrase like, “He was filled with desire.”
219
674000
3149
11:17
or, “She was filled with desire.”
220
677149
2040
11:19
Used more as a noun than as a verb.
221
679189
2890
11:22
So, I would recommend not using “desire” so much to talk about your wants as it can
222
682079
7181
11:29
sound a little bit too formal or can give perhaps the wrong nuance to the situation.
223
689260
5410
11:34
But “wish” is used to express a hope for something or wanting something that is different
224
694670
5779
11:40
from the present situation.
225
700449
1041
11:41
I hope that helps.
226
701490
2009
11:43
Next question!
227
703499
1400
11:44
Next question from Han Yonghe.
228
704899
2011
11:46
I’m very sorry.
229
706910
1859
11:48
“Hey, Alisha.
230
708769
1240
11:50
What's the difference between ‘maybe,’ ‘probably,’ ‘perhaps,’ and ‘possibly?’”
231
710009
4390
11:54
Great question!
232
714399
1321
11:55
“Maybe,” “probably,” “perhaps,” “possibly.”
233
715720
2399
11:58
Okay.
234
718119
1000
11:59
“Maybe,” “probably,” “perhaps,” and “possibly,” these are all adverbs.
235
719119
3421
12:02
They have the same grammatical function.
236
722540
2310
12:04
“Maybe,” “probably,” “perhaps,” and “possibly.”
237
724850
2810
12:07
“Maybe” and “perhaps” are very closely related.
238
727660
3349
12:11
“Maybe” and “perhaps,” they have the same meaning, but just different levels of
239
731009
4700
12:15
formality.
240
735709
1000
12:16
“Maybe” is like the lower level.
241
736709
2141
12:18
The more casual version of the word “perhaps.”
242
738850
2929
12:21
“Maybe I'll go to the beach this weekend.”
243
741779
2210
12:23
and “Perhaps I'll go to the beach this weekend.”
244
743989
2611
12:26
They have really the same meaning but “perhaps” sounds more formal.
245
746600
4099
12:30
“Probably,” however, is different.
246
750699
2361
12:33
“Probably” expresses a higher level of possibility than the other words on this list.
247
753060
5600
12:38
“I'll probably go to the beach this weekend.”
248
758660
2169
12:40
It’s like a 75% to 80% chance the speaker is going to go to the beach this weekend.
249
760829
6480
12:47
“Possibly,” however, “possibly” has more of a nuance of just that something can
250
767309
4960
12:52
be done.
251
772269
1000
12:53
It is possible to do something.
252
773269
1760
12:55
We use “possibly” more in requests.
253
775029
2081
12:57
Like, “Could you possibly blah blah blah for me?”
254
777110
3149
13:00
“Could you possibly send me this file?”
255
780259
2401
13:02
“Possibly” sounds a little too formal for casual conversations and invitations.
256
782660
5219
13:07
But if you're using it at work, for example, “Could you possibly meet me later this week?”
257
787879
4900
13:12
Instead of, “Could you maybe meet me?”
258
792779
2310
13:15
So, the difference between “maybe” and “possibly” and “perhaps” there, “possible”
259
795089
5271
13:20
has that route, yeah.
260
800360
1360
13:21
“Possible,” able to.
261
801720
1429
13:23
So, “maybe” and “perhaps” don't have that nuance.
262
803149
3740
13:26
“Possibly” sounds like, “Is it possible?”
263
806889
2560
13:29
“Is it?”
264
809449
1000
13:30
“Are you able to do this thing?”
265
810449
2091
13:32
“Maybe” and “perhaps” don't contain that nuance.
266
812540
3519
13:36
So, to recap.
267
816059
1601
13:37
“Maybe” and “perhaps” are used to express the same thing, a chance of something
268
817660
4929
13:42
happening.
269
822589
1000
13:43
“Perhaps” is more formal.
270
823589
1381
13:44
“Possibly” is used in a similar way, however, it refers more to simple possibility than
271
824970
5690
13:50
is.
272
830660
1000
13:51
“Are you able to do that thing?”
273
831660
1989
13:53
“Probably” expresses a high chance of something.
274
833649
2880
13:56
Thanks so much for all your questions.
