Question

根據(jù)句意，用括號(hào)中所給單詞的正確形式填空。
【小題1】All the homeless children               (look) after well.
【小題2】I’m not               (certainly) whether I can do it.
【小題3】We have decided not to go, though it was difficult               (decide).
【小題4】I’ve two               (knife). I use them to cut watermelons.
【小題5】When I visited them last night, they               (chat) by the fire.

Answer 1

【小題1】are looked
【小題2】certain
【小題3】to decide
【小題4】knives
【小題5】were chatting

解析【小題1】考查被動(dòng)語態(tài)。所有的無家可歸的孩子都得到了很好地照顧。主語是動(dòng)作的承受者，故用被動(dòng)語態(tài)。故填are looked。
【小題2】考查形容詞作表語。am是系動(dòng)詞，后跟形容詞作表語。故填certain。
【小題3】考查固定句型。It is+形容詞+to do sth“做某事怎么樣”。故填to decide。
【小題4】考查名詞的復(fù)數(shù)。以f或fe結(jié)尾的可數(shù)名詞，要變f或fe為ves。故填knives。
【小題5】考查時(shí)態(tài)。根據(jù)句意可知，應(yīng)該用過去進(jìn)行時(shí)。故填were chatting。
