新概念三 lesson 4
1、Alf did this for two years 为啥有for加时间段前面不用完成时?
2、he will be earning only half as much as he used to.能不能改成 he will be earning only as half as he used to.
3、he will soon be working in an office为什么soon 不放在be后边,不是都要放在助动词后边么?

1.并非有for就必需用完成时态,for 只表示一段时间,并不是完成时态的标志.
此句也可改为Alf had done this for two years.
一般时态表示一般性的陈述
完成时态表示所发生的事情产生了一定的影响
两者都可以描述持续进行的一件事.
2.as ...as句型有两种表达
一是as +adj+as 表示和什么一样
二是倍数+as+adj+as表示多少倍（或者一半）
3.soon是补语,放开头,或主语与谓语之间,或最后.
1、for可以和一般现在时连用 例如I stayed in Beijing for two weeks last winter holiday.
2、数词+as much as，表示的是倍数关系，前面不但可以用half 还可以用two times等 改变后就没有这个效果了
3、soon为频度副词，一般放在谓语前面，系动词be后面。情态动词/助动词和主要动词之间。...
