1、spend vt. 花费;用

其主语为“人”,宾语为“金钱”或“时间”;后面可搭配介词“on + 名词/代词”,或“in(可以省略) + 动名词”。

使用句式为:sb. + money/time + on sth./(in)doing sth.

①They spent 2000 yuan on the TV set./They spent 2000 yuan(in)buying the TV set.

他们花了2000元这台买电视机。

②The writer spent 2 years(in) writing the novel./on the novel.

这位作家花了两年时间写这部小说。

另外:“花钱”还常用以下两个句式:sb.+ pay money + for sth./sth.+cost sb.+money

①They paid 2000 yuan for the TV set.

②The TV set cost them 2000 yuan.

花时间”还常用It takes sb. some time to do sth. 句式。

It took the writer 2 years to write the novel.

2、still

1) 用作形容词,意为“静止的,不动的,平静的”。

如:keep(stay) still保持不动;lie(stand)still躺着(站着)不

动;a still lake/evening 平静的湖/寂静的夜晚。

2)用作副词,表示“还,仍旧”,可以修饰形容词、副词比较组。如:

be still busy 仍然很忙;win still greater success 取得更大成功。

3)辨析still,quiet,silent。still侧重“一动不动”,quiet指“安静”,无动作,无声音,无骚乱,其反义词是noisy(吵闹的、喧哗的);silent指不出声,不说话。

对比:sit still 坐着不动。Be quiet,and the class will begin. 请安静,马上就要开始上课了。

Hearing the answer,be was silent for a minute or more. 听了回答之后,他沉默了一两分钟。

[应用]完成句子

①他个子高,他哥哥更高。

He is tall,but his brother is _________ _________.

②我已经考虑了几个小时,但仍然不能决定。

I have been thinking for hours, but I ______can’t decide.

Key:①still, talker ②still

3、stop…from doing sth. 阻止……做某事

stop 也可换为prevent 或keep.

①Nothing can stop/prevent/keep us from doing that. 没有什么能阻止我们那样做

②This is the best way to stop/prevent/keep such a thing from happening again.

防止这样的事再次发生这是最好的办法。

当该句型用到动词stop或prevent时,后面的from可以省略。

I tried to stop/prevent him(from)smoking, but I failed. 我试图劝他戒烟,但没成功。

但当用到动词keep时,from不能省略。因为省略后得到的是另一句型keep…doing sth.意为“使……不断地做某事”。

I’m sorry I’ve kept you waiting for so long. 很抱歉让你久等了。
