高三英语复习教案（11） （SB I—Units 21-22） ?一、单元考点提示 1.before long;long before before long 意为“不久、很快”（soon,after a short period of time）,其中的before是介词，long是名词，在句中作状语，常与将来时或过去时连用。如： Before long he had to move on again. long before意为“很久以前”，其中的long是副词。long before单独使用时，before是副词。long before后接名词或代词时，before为介词。long before后接从句时，before为连词。该词组常与过去时、过去完成时连用。如： They heard of it long before. I knew your brother long before I knew you. 2.force; make force和make均有“迫使”之义，但有区别。force常含有暴力威胁之意，常用于“force+名词/代词+带to的不定式”结构。如： When he was still a young man, he was forced to leave his homeland for political reasons. The PLA men forced the enemy to surrender(投降). make 所表示的迫使意义没有force强，常用于“make+名词/代词+省略to的不定式”结构。如： What makes you think I’m a worker? How did Lin Feng make the baby stop crying? 注：当make用于被动语态时，其后作主语补足语的不定式要带to。如：The workers were made to work ten hours a day. 3.such… that;so…that such…that和so…that 引导的都是结果状语从句。一般such+名词+that,so+形/副词+that，其具体用法如下： （1）such… that: ①such修饰单数可数名词，即such+a/an+(形)+单数可数名词，如： It was such a hot day that nobody wanted to do anything. This is such a good book that I have read it several times. ②such修饰复数可数名词，即：such+(形)+复数可数名词，如： These are such small shoes that I can’t wear them. ③such修饰不可数名词，即：such+(形)+不可数名词，如： He made such rapid progress that he did well in mid-term examination. ④such与one,no等词一起修饰名词时，这些词要放在such的前面，即： one no any all 单数可数名词 many +such+ 复数可数名词 ,如: some 不可数名词 several few He has made some such mistakes. I have met many such people. One such book is enough. There is no such a word in the dictionary. All such story-books must be collected. I have few such good books. I have never met any such persons. 注：such a lot of +名词，而不能说a lot of such+名词。 （2）so…that ①so修饰形容词或副词，即：so+ 形/副+that，如： Mr Wang is so busy that he can’t leave his office. He ran so fast that I couldn’t catch up with him. ②so也可以修饰名词，但该名词前必须有many,few,little等表示数量多少的词修饰。如： many so+ +可数名词复数 few much so+ +不可数名词复数 little 该句
