一道选择
there is a new problem involved in the popularity of private cars ____road conditions need ___.
A.that;to be improved
B.which;to be improved
C.where;improving
D.when;improving
第二个空为什么填to be improved?need之后不是用动名词表示被动含义吗?
答
need improving = need to be improved 两种都能表被动的.
所以主要还是看that, 这里that引导一个同位语从句,解释 a new problem的具体内容.
答
A
need doing=need to be done
答
不一定的， need后面也可以接 to do
而且 表被动接to do 的情况多， 读着也比较顺~~
答
sth need to be done
=sth need dong.
答
因为第一个空只能选that 引导同位语从句,所以后一个空也只能用to be improved 了,;improving 也可填上,但顾及第一个空只好选A.
答
a
