Book 4 Unit 1 重点短语讲解

1. She devoted all her life to medical work for Chinese women and children. (P1)

【归纳】devote... to... 意为“献身，致力于”，指把自己的时间和精力等奉献给某种工作或事业。devote 的宾语是oneself, one’s time, one’s life等，to是介词，后接名词、代词或动名词。

【延伸】to作介词后可接doing / n. / pron.，常见的动词短语如下：be / get used to习惯于；get down to开始认真（做某事）；lead to通向，导致；look forward to盼望，期待；pay attention to注意；prefer doing to doing宁愿……不愿……；stick to坚持；object to反对，不赞成；see to照料，照顾；be up to从事于；belong to属于；in addition to除……外。

【易错点】devote后没有宾语时，应用be devoted to... 形式。如：

His whole life was devoted to teaching.

2. By chance I came across an article about a doctor called Lin Qiaozhi... (P6)

【归纳】by chance = by accident意为“恰巧，碰巧，偶然，意外”。

【延伸】give sb a chance 给某人一个机会；get / have a chance有机会；take a / one’s chan ce 碰运气，冒一冒险；there is a chance that...有可能，有希望。

【易错点】by any chance与by chance 意思不同，by any chance表示“万一，也许”，在句子中作插入语，它一般用于否定句，疑问句或条件状语从句中。如：

If, by any chance, he failed to come, we’ll ask John to work the machine. 万一他不来，我们就叫约翰开机器。

3. It was a small book explaining how to cut the death rate f rom having and caring for babies. (P6)

【归纳】care for相当于look after，意为“照顾，照料”，且较正式；也可表示“喜欢”的意思。如：

His son cared for him when he was ill.

In fact, I don’t really care for basketball.

【延伸】take care小心，当心；take care with 当心……；take care of照顾；wi th care小心,谨慎；care to do愿意去做；under the care of在……的照料下, 在……的保护下；care about 关心, 担心。

【易错点】care about和care for在表示“关心，担心”意思的时候，用法是一样的，基本可以通用。在表示“介意，计较”等意思的时候，要用care about，后面一般接表示事物的词。在表示“关怀，照顾，喜欢，愿意……”等意思的时候，要用care for。

4. I looked carefully at the text and realized that it was intended for women in the countryside. (P6)

【归纳】be intended for意为“打算为……所用，打算供……使用”。

【延伸】intend to do sth想做某事；be intended to do sth打算被用来……；it is intended that 企图, 意图是；intend sb to 打算让某人做某事；had intended to do... = intended to have done... 表示本打算做而未做……。

【易错点】intend引导that从句时，从句用虚拟语气（should + 动词原形），should可以省略。
