题目

1.Pointing to the house on whose roofs grew lots of bush,the old man told me that was___i would stay.
where
2.Because of ___high demandfor Type AB blood,___supplies of it are usually limited.
a,the.
请具体解释下.
1.为什么不用what或which?
2.可是high不可数，为什么用a;supplies显然是可数复数，虽然是特指，但为什么要加the?

答案

1 stay不是及物动词,不能用what 或which作宾语.
第2题第一空不是看high而是看后面的中心词demand,就像a tall man一样.第二空就是构成the.of.,用定冠词.
