Though _____,swimming does as much good. Atired B we tire out C tiring Dit is tired by the time 用于什么时态呢 It's ____they have seen lots of American films that the learners of English have been used to American accents A as Bfor C because Dsince
解题思路： 如下
解题过程：
Though _____,swimming does as much good.
Atired B we tire out C tiring Dit is tired
答案为C，考查省略句。在时间条件让步等状语从句中，如果主从句的主语为同一个，而且从句的谓语为be，可以将从句中的主语和be同时省略。主语为swimming，从句应为令人疲倦，所以为Though （it is） tiring, swimming does as much good.如果选择B，应为Though we are tired out尽管我们筋疲力尽。
by the time 表示到....时候为止，具体时态如下：
1.表示将来的时间。
主句用将来完成时，而从句用一般现在时来表示将来的动作。
如:I will have finishied the work by the time my father comes back.
2.表示过去的时间。
主句用过去完成时，而从句用一般过去时。
如：He had built a lab for himself by the time he was 12 years old.
It's ____they have seen lots of American films that the learners of English have been used to American accents
A as Bfor C because Dsince
答案为C，考查强调句型强调原因状语从句，此时只能用because。
