A.that B.which
A writer must not write for the ages past,but for ___he lives and those which are to follow.
a.that in which b.that where
都 要详说原因哦 还包括另一下项为啥不对的道理
答
1.A
that引导的为problem的同位语从句,也就是阐述该problem为“road conditions need to be improved”.同位语从句只能用that引导.
2.A
that指代与ages同样意义的一个事物,做代词,同时也是后面定语从句的先行词.lives为定语从句的谓语,要与ages搭配必须在前面加一个介词in,即in the ages,表达“在某个时间”的意义,用作从句的时间状语.选项B适用于表示地点的概念,只能用来做地点状语,不能与ages相搭配.
