本单元的语言点是关于 Make, Let, Allow 的用法，请看下面的解释和例句

Make, Let, Allow

Make - active form 主动形式

The verb 'make' has several meanings in English. When Helen says 'I can't make people call', she means that she cannot force people to call; she does not have the power to control or change the situation.

When 'make' means 'force' or 'control', in the active form, it is followed by an object and the bare infinitive (原形不定式/不带'to'的不定式，infinitive without 'to').

 

Be careful: in the active form, 'make' is NOT followed by 'to', and it is NOT followed by an -ing form:

The teacher made us to do our homework -WRONG

The teacher made us doing our homework -WRONG

The teacher made us do our homework –RIGHT

Make - passive form 被动形式

When 'make' means 'force', in the passive from, it is followed by the infinitive with 'to'.

 

Let 容许,让

If you 'let' somebody do something, you give permission or you allow them to do something. Helen says 'if you want him to move in, you'll have to let him have a discount.'

When 'let' means 'allow' or 'give permission', it is followed by an object and the bare infinitive (infinitive without 'to').

 

Be careful: 'let' is NOT followed by 'to', and it is NOT followed by an

-ing form:

The teacher let us to leave early - WRONG

The teacher let us leaving early - WRONG

The teacher let us leave early – RIGHT

Allow 准许,许可;允许

Allow has a similar meaning to 'let'. When Helen's dad says 'Helen, you know I can't allow it.' He means that he can't give permission.

Allow can be used in 2 ways:

1. It is followed by an object. The object can be a noun, or it can be an -ing form.

 

2. It is followed by an object (noun or pronoun) and the infinitive with 'to'.

 

Be careful: in this pattern, the object is NOT followed by an -ing form:

The teacher allowed us leaving early - WRONG

The teacher allowed us to leaving early - WRONG

The teacher allowed us to leave early - RIGHT

Passive forms are also possible.
