Teaching important and difficult points 1.

Help students distinguish many verbs using V-ing or infinitive as their objects.

Step1 Warming up Show many pictures about the use of V-ing in our daily life to arise students’ learning interest. Step2 Discovering

Get students to underline the sentences with V-ing in the reading passage. Then clarify them into two parts, one is V-ing used as subject, and the other is used as object. Step3 Explanation 一、动词ing形式做主语

1.

动词ing形式做主语时，表示经常性、习惯性的动作，谓语动词要用单数形式。如：Running is my favorite sport. 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 no use crying over spilt milk.

覆水难收。

It is a waste of time talking with them. 和他们争论是浪费时间。

It is no good worrying about it. 担心它是没有用的。

练一练

用动词ing形式做主语的形式改写下列句子

例：It is necessary to get water from wet to dry places.

—Getting water from wet to dry places is necessary. 1. It is nice to help people in need of help. 2. It is not easy to grow super hybrid rice. 3. It is not difficult to learn more about farming.

二、动词ing形式做宾语

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：advise, admit, appreciate, avoid, bear, consider, delay, deny, enjoy, escape, finish, forbid, imagine, keep, mind, mention, permit, practice, quit, risk, suggest等。如：We’re considering paying a visit to the Science Museum. I tried to avoid making the same mistake. Would you mind opening the windows?

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。如：remember, forget, regret, stop, mean, try等。

试比较下面两个句子的意思：

1）He stops to read when the bell rings. 2）He stops reading when the bell rings. 小结：

Stop to do sth.停下来去做某事

Regret to do sth 遗憾地做某事

Stop doing sth. 停止做某事

Regret doing sth 后悔做过某事

Remember to do sth 记得要去做某事

forget to do sth 忘记要去做某事

Remember doing sth 记得做过某事

forget doing sth 忘记做过某事

Try to do sth 尽力做某事

mean to do sth 想要做某事

Try doing sth

试着做某事

mean doing sth 意味着做某事

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. 翻译：

这台电脑需要修一下。

4.

动词-ing形式作介词的宾语。常见的动词短语有insist

on, feel like, dream of等。要特别注意: be / get used to, look forward to, pay attention to, stick to, object to, devote to等中的to都是介词而不是动词不定式符号。如：

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

2）I’m looking forward to receiving your reply. Step4 Exercise 1. 选择最佳选项
