(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：
