worth的用法及搭配(worth有介词词性吗)

解析:他们三个单词的意思都有“值得的,有价值的”,具体用法如下:

1,Worth

句型结构是1:be worth + 动名词 (不加不定式)

注意:动名词一定是主动形式,而且表示被动;动词必须是及物动词,如果是不及物动词需加介词变成及物动词短语。因为,动名词的动词的逻辑宾语就是该句的主语。例如:1,The book is worth reading.(这本书值得读。阅读的逻辑宾语就是该句的主语book)

2,The song is worth listening to.(这支歌值得听。listening后要加to)

句型结构2: be worth可加money, price, time等名词

A ship is worth more than a million dollars. 这轮船价值可达一百多万美元。

2,Worthwhile

句型结构1: 动名词/不定式+be worthwhile

Explaining a job fully to a new employee is worthwhile.

To explain a job fully to a new employee is worthwhile.

给新雇员详细说明工作的要求是值得的。

句型结构 2: It is + worthwhile + 动名词/不定式(英语中一般不习惯把动名词或动词不定式放在主语的位置,常用it做形式主语,所以,就变成了上面的句型。)

例如:

It is worthwhile to explain a job fully to a new employee.

It is worthwhile explaining a job fully to a new employee.

向新员工全面讲解一项工作是值得的。

3,Worthy

形式 1: be worthy of 名词/动名词的被动形式(不加不定式)

This issue is worthy of careful study. 这一问题值得仔细研究。

This issue is worthy of being studied carefully. (问题值得细致研究。)

形式 2: be worthy + 不定式的被动形式

例如:

The issue is worthy to be studied carefully.

问题值得细致研究。

总结一下它们的句型结构如下:

Sth’s worth doing .(某事值得做)

Sth’s worthy of being done.(某事值得做)

Sth’s worthy to be done.(某事值得做)

It’s worthwhile doing/to do sth.(某事值得做)

这几个句型虽然不一样,用词也不一样,但是他们的含义是一样的。
