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。
