关于英语选择题
1 that they were wrong in these matters______now clear to us all
A is B was C are D were 这道题怎么做
2 mathematics_____the language of science
A are B are going to be C is D is to be 这道题为什么不是are
答
C;
现在清楚,matters,复数；
mathmatics是数学学科,s不是表示复数；什么是主语从句一个从句，在主句中充当主语；比如：What I want is just a dog!;what I want 就是 句子的主语;但是本身又是一个小句子；有问题请追问~~
