一道英语选择题a
cars do cause us some health problems ---in fact far more serious ---than mobile phones do.
a,one b,ones c,it d,those
答
选B
A 答案指代单数可数名词,可排除
C 答案指代单数可数或不可数名词,可排除
B D答案都可以用来指代可数名词的复数,但是:ones为泛指 ,即相当于这题的problems ,those 为特指, 相当于the +ones /the +名词,即相当于这题里的the problems.
1、这个句省略了好多东西,补全: cars do (确实)cause us some health problems ---in fact (cars curse us )far more serious (problems )---than mobile phones do.
2、把补全了的括号里的problems 用ones 代替,答案就出来了,实际上它在这里确实表示泛指,而不是特指的problems .
3、比较一下:The cars made in Japan are much cheaper than thosemade in Europe.(those 特指欧洲生产的cars,换成the cars也行 )
望采纳,谢谢!
