1.此题考查倍数表达句型.
倍数表达法:倍数词(three times) + 名词
如:I have three times your income.我的收入是你的三倍.
2.后面是一个名词性从句.
如果用that引导,表明该从句不缺少任何成分.
但是it was ten years ago中明显缺少一个表语(was的后面),而只有疑问代词what可以有此功能.
倍数词+times+what从句就是在一种表示倍数的结构,记住就行了。
eg。 This is three times what you normally charge
population 是名词,表示数目
that 没有数字的意思
这是一个从句。
如果用that引导,表明该从句不缺少任何成分。
但是此处应是指the population,故只有疑问代词what可以。
