高中英语 Book 4 Unit 2重点短语讲解新人教版必修4

Book 4 Unit 2重点短语讲解1. Dr Yuan searched for a way to increase rice harvests without expanding the area of the fields. (P10)【归纳】search for 意思是“寻找，搜寻”。

【延伸】search into调查；search out寻找到；search through 把……仔细搜寻一遍；search one’s memory 寻思，追忆；search one’s heart 扪心自问；in search of 寻找，寻求。

【易错点】search some place意为“在某地搜查”；search for sth 意为“寻找某物”；如：s earch sb 搜身；search for sb 寻找某人。

2. Dr Yuan is quite satisfied with his life. (P10)【归纳】be satisfied with意为“对……感到满意”。

【延伸】to one’s satisfaction 使某人满意的是；in satisfaction 满意地；satisf y sb that使相信……；satisfie d one’s doubt消除某人的疑虑。

【易错点】satisfactory / satisfy-ing：都是“令人（感觉到）满意的”意思，其句中的主语或修饰的名词大都是表示事物的名词，两者一般可以换用。

而satisfied意为“满意的”，是人的主观感受，其句中的主语或修饰的名词一般都是表示人的名词。

3. He would much rather keep time for his hobbies. (P10)【归纳】would rather意思是“宁愿”，后接动词原形，没有人称和数的变化。

【延伸】would rather do宁愿做某事；would rather have done表示过去的想法，通常可译为“(本来)宁愿做某事；I’d rather not，表示委婉的不同意，意为“我宁愿不……”；prefer to do rather than do宁愿……而不愿……；prefer doing to doing宁愿……而不愿……。
