3.Why not go by underground? 为什么不坐地铁去呢?

Why not do ?是个常用句型,用来提建议,意为 "为什么不?"

思考:what about?和how about?也用于提建议,它之后的动词是什么形式?

 小试牛刀:How about ____________?我们去游泳怎样?

4.Native English speakers can understand each other even if they don't speak the same kind of English 以英语作为母语的人,即使他们所讲的语言不尽相同,也可以相互理解。

  句中even if是个连词短语,引导让步状语从句,含义是"即使,尽管"。让步状语从句的动词用一般现在时表示将来假设。Even if 相当于even though,两者意思一样,用法相同。

 潜心辨析:even if/though与as if/though

前者引导让步状语从句,意为"即使","尽管";后者引导方式状语从句,意为"仿佛""好像"。

○1I can still remember,_______________it was so long ago

○2It seems______________our team is going to win

5. ○1For example,India has a very large number of fluent English speakers

○2China may have the largest number of English learners

 潜心辨析:a number of/the number of

1、a number of 意为"一些,若干",后接复数名词或代词,作主语时谓语动词须用复数形式。Number前可用large,great等词修饰。

2、the number of 意为"~的数量"中心词是number,作主语时谓语动词须用单数形式。 小试牛刀:

○1____________students in our school _____________from the countryside

我们学校很多学生来自乡下。

○2__________cars ____________increasing in our country

我国汽车数在增加。

6. Only time will tell 只好由时间作答了。

该句是一个省略句,完整句是:Only time will tell whether Chinese English develops its own identity,为避免与上句重复而省略tell后的宾语从句。

Will Jack be able to return home ?Only time will tell 杰克能否回到家乡,只能由时间回答了。
