Learning more about farming is not difficult.

Doing research in the countryside is not as easy as in the city.

Getting rid of hunger is very important for some African countries.

Explaining this again is important or we will confuse the students. 2. Which verbs are followed by–ing? Which by the infinitive? First write doing or to do over the correct group. Then write the verbs in the box in the correct columns and finally practise making at least four sentences with them.

一、动词-ing形式作主语

1. 动词-ing形式作主语，表示一般或抽象的习惯性行为，谓语动词用单数。如：

Reading aloud is very important for us to learn a foreign language.

Going to bed early and getting up early is considered to be a good habit. 2. 在一些句子中，常用it作形式主语放在句首，而把真正的主语放到句末。

如：

It is very important remembering others’ names.

It is no use crying over spilt milk.

二、动词-ing形式作宾语

1. 有些动词后只能跟动词-ing形式作宾语，而不能跟动词不定式作宾语。有此用法的动词有：allow, advise, admit, appreciate, avoid, bear, consider, delay, deny, enjoy, escape, finish, forbid, imagine, keep, mind, mention, permit, practice, quit, risk, suggest等。如：

My mother advised asking a doctor to come and examine my eyes.

We’re considering paying a visit to the Science Museum.

_______ imagine suggest avoid admit practise both to do and doing hate love prefer remember regret

2. 有些动词后既可跟动词-ing形式作宾语, 也可跟动词不定式作宾语, 但用法和意义都有所不同。这些动词是：remember, forget, stop, regret, try, mean等。如：

I remember meeting her at a party once.

I want to try playing soccer this spring. 3. 动词-ing形式用在动词need, want, require等后表示“需要”时, 用动词-ing形式的主动形式或者用不定式的被动式表示被动意义。如：

The carpet really wants cleaning. =

The carpet really wants to be cleaned. 4. 动词-ing形式作介词的宾语。要特别注意: be / get used to, look forward to, pay attention to, stick to, devote to等中的to都是介词而不是动词不定式符号。如：

My father is used to going to bed late and getting up very early.

I’m looking forward to receiving your reply.
