医生劝我长期修养.
He recommended that the prisoners (should) be released.
他建议释放俘虏.
[注意] recommend引导宾语从句时, 从句动词需要用虚拟语气形式, 即 “ should +do”或者do.
(3). 同义词: advise/suggest vt.建议.
二、词义辨析
1.如何正确使用“offer,provide, supply”?
offer 指主动提供。常构成“offer sb. sth.;offer sth. to/for sb.”结构。
provide 提供,供应,供给(有用的或必需的物品)。常构成固定结构“provide sth.(for sb.; provide sb. with sth.”。
supply 供应,供给(所需要或所要求的物品)。常构成固定表达“supply sth. to sb.; supply sb. with sth.”。
[例如]
The police are offering a big reward for any information about the murder.
警方悬赏一大笔赏金给提供有关这一谋杀案情况的人。
The firm has provided me with a car.
公司提供给我一辆车。
They supply gas to consumers.
他们向消费者供应煤气。
2.although, though, as, in spite of和despite的区别
这几个词都有 “虽然, 尽管”的意思. 前三个词是连词. 而in spite of和despite是介词.
(1). although和though是从属连词, though更为常用, 而although则更为正式一些. although和though引导的句子既可以放在主句前, 也可以放在主句后面. 两者在句中经常可以互换.
例如:
Although (though) he is a little child, he knows a lot.
[注意]although和though引导的句子不能与but和however连用.
例如:
(误)Although he is rich, but he is not happy.
(正)Although he is rich, he is not happy.
(2). though引导的从句还可以用倒装语序, 即把句子中的表语, 状语提前放到句首. 而as引导的让步状语从句则必须把句子中的表语, 状语提前放到句首. 两者可以互换.
例如:
Tired though (as) he was, he was still working hard.
[注意]如果表语是单数名词, 提到句首时需要去掉冠词a..
例如:
Child though (as) he is, he knows a lot of knowledge.
(3). in spite of和despite是介词, 后面接名词或代词.
例如:
He keeps working in spite of (despite) his illness.
他不顾有病, 坚持工作.
In spite of (Despite) all this discomforts, the Curies worked on.
居里夫妇不顾一切困难, 继续工作着.
4.不同的 “表达”: illustrate, suggest, express
1.illustrate(以实物、例子、图解)说明,例证,阐明。
例如:
The book was illustrated with color photographs.
这本书配上了彩色照片。
Explain and illustrate the main use of the present perfect tense.
解释并举例说明现在完成时态的用法。
2.suggest暗示,间接表明。
