Answer 1

1. 10% boys in my class_____from Paris ,that is to say, one out of ten boys in my class____from Paris.
答案： D.are,is
10% boys 核心是复数名词 boys，所以 选 are；one out of ten boys （原题漏掉 ten，整体意思是1/10）的核心是 one，应该视作单数，选用 is。

2. Every hour and every minute ____ important.
答案： C. is
主语前如果有every，each 修饰，不管并列几个主语都应该视作单数。

3. Half a dozen _____ were standing at the corners
答案： C.youth
youth 同 people，police 一样，是集合名词，单复数同形。

4. _____is a well-known musician.
答案： D.This old friend of Jack's
应该选用双重所有格（杰克的这个老朋友）。

5. At the end of _____ these clothes shocked many people by their sharp colour.
答案：C.the sixties'
At the end of the sixties'，后面省略了 clothes，意思是“在60匹布的最后”；the sixties' 属于名词所有格，复数名词的所有格直接在复数形式词尾 s 后加“'”。

6. Every _____is important to the man telling it.
答案;: C.story
下文中有 telling it，其实就是 telling the story。

7. A number of sheep_____died from a strange illness.(have)
答案：have
sheep 也是集合名词，单复数同形，a numger of 表示“许多”，用在复数名词前。
8. Fish ______dying because of the polluted water.(be)
答案：are
鱼类名词多数单复数同形，这里的 fish 指的是鱼类的群体，所以视作复数。
