Greeting and revision T: In the last period, we’ve learned some new words and expressions. Now let’s review them. Look at the screen, please. Try to think of their meanings and their usages. Then complete the exercise on the screen to check if you can use them correctly. After finishing it, you may check your answers with your partners. Step II Grammar There are two tasks in this step. One is to do some explanations about the structure; the other is to do some exercises. Task 1 1. 动词-ing形式的构成：是在动词末尾加

-ing 形式构成，因此又叫动词的

-ing 形式。如：

do-doing, be-being, ask-asking, etc. 否定形式：not+ -ing 构成

2. 动词-ing形式不能单独作谓语，没有人称和数的变化，但可以有自己的宾语和状语，还有时态和语态的变化。

3.

-ing 形式主要考查其在句子中作定语和状语的用法

European football is played in 80 countries, ___

it the most popular sport in the world.

making

B. makes

C. made

D. to make 解析：Making it the popular sport in the world为现在分词短语作结果状语，这类分词短语常放在句子的后面。如：His parents died, leaving him an orphan. 4.

动名词：在句子中起名次作用，可作主，宾，表，定的成分。

1.

动名词和不定式作主语，一般都可以使用形式主语it，而将动名词或不定式放在句尾。但是在下列句型中，一般宜用动名词，不宜用不定式来代替：

It’s no use doing …

It’s no good doing…

It’s a waste of time doing …

例如：

It’s no use going there today; he won’t

be at home.

It’s a waste of time arguing about it.

而在It’s important/necessary/advisable/ essential/fitting …

这类句型中，只能用不定式，如：

It’s important to learn foreign languages.

2. 在allow, advise, forbid, permit后直接跟动名词作宾语，如果有名词或代词作宾语，则构成“

allow／advise／forbid／permit ＋名词／代词＋不定式（宾语补足语）”之形式。如：

We don't allow smoking here．

We don't allow anybody to smoke here．

3. 动词need, require, want意为“需要”时，后跟动名词的主动式或不定式的被动式作宾语，意义没有区别。如：

The window needs／requires／wants cleaning／to be cleaned．

4. 在begin, continue, love, like, hate, prefer, intend, start 后用动名词和用不定式作宾语均可，意义没有多大区别。

5. 动词forget, go on, mean, regret, remember, stop, try, be used to, can't help后跟动名词和跟不定式区别较大，须注意:

forget, regret, remember后跟动名词，动名词表示已经发生的动作；后跟不定式表示将要发生的动作。

go on doing

继续做原来做的事

go on to do

接着做另一件事

mean doing 意味着要做某事
