Answer 2

1 . We must obey our teachers

• Must is a modal verb that is used for obligation
• Must is also used to give orders and advice
• When we talk about something that we need to, then Must is used
• When the sentence is given in future or present tense the modal verb must is used

2. She ought to move this time

• The modal verb used for expressing is Ought to
• It describes the correct way to do or right way to behave
• There is no past form for the verb ought to

3. He need not buy a car

• Something that is not needed is described using the verbal word need not
• This is the negative form of need and is also used as obligation or necessity

4. He works hard lest he should fail

• Should is used to express something that is possible
• It is also used to give recommendations or opinion
