Hi everyone. Okay, we're going to have a look at modal verbs today.

2
00:00:04,879 --> 00:00:10,900
Now, remember, a modal verb accompanies a main verb and it gives us extra information.

3
00:00:11,300 --> 00:00:13,859
It tells us something about that main verb.

4
00:00:15,000 --> 00:00:17,260
The first one is must.

5
00:00:18,140 --> 00:00:20,940
Now, must is a modal verb of obligation.

6
00:00:21,820 --> 00:00:26,199
It's for laws and self-imposed obligation.

7
00:00:26,199 --> 00:00:36,079
something you are telling yourself you must do so for example at the moment we must stay at home

8
00:00:36,079 --> 00:00:43,880
we must stay at home it's the law now imagine you have an exam tomorrow you don't but imagine

9
00:00:43,880 --> 00:00:53,679
you want to get a good mark so you say I must study because you want to pass I must study

10
00:00:53,679 --> 00:01:03,039
The next one is have to. Now, have to is for obligation as well, but it's what we call external obligation.

11
00:01:03,640 --> 00:01:11,739
Somebody else is telling us we have to do it. We probably don't want to, but we have to.

12
00:01:12,280 --> 00:01:18,299
For example, your mum says you have to tidy your bedroom. You have to tidy your bedroom.

13
00:01:18,299 --> 00:01:24,000
The next one is should or ought to.

14
00:01:24,680 --> 00:01:26,180
Should or ought to.

15
00:01:26,739 --> 00:01:30,700
And this is for advice or mild obligation.

16
00:01:31,900 --> 00:01:37,519
So, for example, you should go to bed because you are tired.

17
00:01:38,620 --> 00:01:43,340
Or, we all ought to eat more healthily.

18
00:01:43,780 --> 00:01:44,579
It's a good idea.

19
00:01:44,879 --> 00:01:47,359
We ought to eat more healthily.

20
00:01:48,299 --> 00:01:48,879
Thank you.
