Use of Must and Should - Common Grammar Errors in English


source: Twominute English    2013年11月13日
The difference between these two words is the urgency or the imperativeness of the task. Is it something that really has to be done, and can't be avoided? Then use 'must'. If it's something that can be done, and it's recommended that it's done, then use 'should'.

0:07 In this lesson, we will learn about how to use ‘must’ and ‘should’.
0:17 Hey Jack! Tell me, do you know the difference between ‘must’ and ‘should’?
0:22 I think I do. You use these words when you suggest that somebody has to do something.
0:28 That’s right. You must learn the difference between these two words.
0:33 You used must instead of should, you could also have said ‘You should learn the difference between these two words’. Right?
0:42 That’s right! But learning the difference is very important, that’s why you must know it.
0:48 So when something is very important you use must?
0:53 Correct! When you can’t avoid doing something, or doing it is very important, then you use ‘must’.
1:00 And you use ‘should’ when you want to recommend that something should be done, or when a person ought to do something, but it’s not a strict requirement.
1:10 That’s correct! You know the difference now. You should give yourself a treat!
1:16 I should, so it’s not a requirement and I may or may not do it.
