特想问问as和那个while when 的区别 还有代词中that one ones those的区别

Answer 1

1.Cars do cause people some health problems, in fact far more serious than those computers do. A. one B. ones C. it D. those
those表那些，computers 是负数。 one是单指，用于单数。 Ones不能单独用，要配合those 变成those ones。 it不能这样用在从句中

2. China __has developed___ at a tremendous rate, an outstanding achievement never seen before, during the past two decades.
A. developed B. has developed C. is developing D. had been developing
因为有during the past two decades 所以是现在完成

3. __To extend___ participation in public decision-making, telephone conference calls are widely used. A. Extend B. Extending C. To extend D. Having extended

这是目的状语从句。 to do 表目的

4.37. Tears of joy and happiness came to my eyes ___as__ we won the first prize in the sports meeting
A. while B. as C. unless D. before
as 表原因。 因为我们赢得了比赛所以什么什么
while表同时发生。但后面并不是进行时 说明不是在强调同时发生
