Answer 1

1.In _______people, the areas of the brain that control speech are located in the left hemisphere.
A.mostly of B. most C.almost the D.the most of

这道题选B。A：mostly是副词，不能这么用，只能是most of；C：almost也是副词，不能直接就接名词the people；D：没有这种用法。
2. （ ）is not clear to researchers.
a. why dinosaurs having become extince
b. why dinosaurs became extint
这道题选A。因为这一句是要选一个原因状语从句来做主语，只有名词、名词性短语或从句才能做主语。A是完成时的进行时态来做主语，其实很多题目都是要选这种句子，比较典型。

Answer 2

第一题选B most people 这里应该是指代人的身体
第二题选B Why dinosaur became extinct 是主语从句。

Answer 3

我觉得第一题选A，它是个介词短语，应该用of结构吧，供参考
第二题是不是单词有问题啊，应该是extinct，该选A

Answer 4

我觉得第一题应该是of结构，所以选D
第二题选B 主语从句

Answer 5

B B
