Question

根據(jù)句意，用括號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4:I’ve two               (knife). I use them to cut watermelons.

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

小題1:考查被動語態(tài)。所有的無家可歸的孩子都得到了很好地照顧。主語是動作的承受者，故用被動語態(tài)。故填are looked。
小題2:考查形容詞作表語。am是系動詞，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:考查名詞的復數(shù)。以f或fe結尾的可數(shù)名詞，要變f或fe為ves。故填knives。
小題5:考查時態(tài)。根據(jù)句意可知，應該用過去進行時。故填were chatting。
