英语完形填空
A UN report says that the world population will pass six billion by the end of the 20th
century.This is just ten years after the population __1__ five billion.Tt is sard that __2__the year of 2010,it may be seven billion.
1.A.get B.gets C.gets on D.gets in
2.A.at B.to C.by D.since
1.答案给的是B,但是after the population ...five billion 应该是过去式啊.不是应该got吗?是不是题目出错了?
2.为什么是by不是at?
sard 改成said

"This is"已经告诉我们这是一般现在式,做称述句,所以应该用第三人称单数；by在这里是表现到一段时间,而不是具体指特定某个时间,这样有个时间过去的感觉,是固定搭配.
