地球那边 共回答了13个问题
|采纳率100%- 第一题选A aboard是 上(飞机,船等),board是 板 的意思,故先排除C,D.而在此句中主句和从句主语一致,所以从句中只需在介词后用动名词形式即可,无需重复主语we.
第二题选A 从 have used 可以看出是现在完成时,故排除C,因为它用于描述一件事发生的频度,而不用于形容一段时间.B前面少了介词,故排除.而D的意思是 在某个时候,故排除.原句的意思是:你应该已经用了一段时间的的电脑了吧.

|采纳率- 1.B before 在这里做介词用,所以后面应该跟动名词形式。
2。A 现在完成时常用的两种时间状语,一种for引导,跟时间段;一种since引导,跟时间点。some time 是一些时间的意思,所以应该由for 引导。 - 1年前

橙子的记忆 共回答了28个问题
|采纳率85.7%答:一个动词有两个由that引导的宾语从句用and并列,第一个可以省略,第二个不能省略,原因是怕引导误会.
比如某人说了两句话.Sb.said (that) he did A and that he did B.
第一个that省略没有关系,我们知道是sb.said的内容.后面有个that,则知道他说了两件事情.
第二个that如果省略了:
Sb.said (that) he did A and he did B.这句话中的and可以理解为并列两个句子,句子一是个复合句:sb.said he did A,句子二是he did B.
我们以为他说了什么事情之后又做了另一件事情.
这就是第二个that不能省略的原因,我猜.一般语法书只讲规则,并不会回答你这个为什么的问题.
记住:凡是省略,则一定可以还原!说多了的话,不想重复,能省则省.谁都知道省了什么.
不能省略,则一定有这个必要,或是怕引起歧义,或是怕句意不明.1年前查看全部
