点，如果difference表示"不同"这个概念，则是不可数名词，无复数形式。

2．And if we are feeling down or lonely, there is nothing better than to see the smiling face of a good friend.

"There is nothing better than to do..."此处表示"没有比...更好的了"。

　　例如：

There is nothing better than to sit in a pub drinking.

没有比坐在酒吧里喝酒更好的事了。

3．Words a are important, but the way a person stands, folds his or her arms, or moves his or her hands can also give us information about his or her feelings.

此句中用了几个并列的谓语动词，要注意英语并列成分的规则：除了最后一个并列成分之前用一个并列连词以外，前面的并列成分都可以用逗号隔开。

再如：

While they were walking, they were talking, laughing and playing games. （并列的-ing形式）

Note: 要注意并列的成分的前后一致性，这是单项填空的常考题型。

四、语法复习

　　(一) 动词的-ng形式作主语、宾语和表语：

1）动词的-ing形式作主语时，常表示概括性的或者一般性的行为。例如：

Fighting broke out between the South and the North. 南方与北方开战了。

Losing her new bicycle made her so upset.

她的新自行车丢了，搞得她心烦意乱。

2）动词的-ing形式作宾语时，既可以作动词的宾语，又可以作介词的宾语。 某些动词或者动词短语后常接动词-ing形式作宾语。

　　例如：

Would you mind turning on your radio, please? I want to hear the hour's news.

请你打开收音机好吗？我想听听本时的新闻。

The sparrow was so lucky that it just missed being caught.

那只麻雀真幸运，它刚好没有被射中。

　 3）动词的-ing形式可以作表语，表示"什么事是某事"。

　　 例如：

　　Her job is washing，cleaning and taking care of the children.
