地球的体积是月球的四十九倍。
The production now is three_times_what it was ten years ago.
现在的产量是十年前的三倍。
[运用提升]
(2008·陕西)Ten years ago the population of our village was________that of theirs.
A.as twice large as
B.twice as large as
C.twice as much as
D.as twice much as
答案:B 本题考查了倍数的表达法。句中倍数表达的正确形式为“倍数+as+adj./adv.+as”,故A、D两项错误。当population表示“人口数量”常用large而不用much修饰。
8.This produced a chain reaction, which made it possible for life to develop.
这就产生了一系列的反应,使得生命就可能发展了。
这是“make it+形容词/名词+to do sth.”句型。该句型中it为形式宾语,指代后面的不定式结构,形容词或名词为宾语补足语。
People in the west make_it_a_rule_to buy Christmas presents for their relatives and friends.
在西方,人们常在圣诞节时购买礼物给亲属和朋友。
点拨:it作形式宾语,除指代不定式结构外,还可指代that引导的宾语从句。
They made it_clear_to_the_public_that they did an important and necessary job.
