參考答案:
1.正確答案:D答案解析:表示“數百”、“數千”、“數百萬”等不確切數目時,要用hundreds / thousands / millions of結構表示。D中hundreds of times意思是“數百倍”。答案為D.
2.正確答案:A答案解析:the earth is round是客觀真理,所以不管句子其它部分用什么時態(tài),這個句子都用一般現在時。
3.正確答案:D答案解析:根據句意可知應該用完成時,所以A答案錯誤。have been…表示狀態(tài),可以和表示一段時間的短語連用。have made和have become都是瞬間動詞,不能和表示一段時間的短語連用。
4.正確答案:C答案解析:taste是系動詞,taste nice構成系表結構,不用被動語態(tài)。但第二個空格處應該用被動語態(tài),因為hamburgers與sell out之間是被動的關系。所以答案是C.
5.正確答案:B答案解析:such可以修飾可數名詞單復數和不可數名詞,名詞前可以有形容詞作定語,其結構是“such +a/an+形容詞+可數名詞單數”,“such+形容詞+可數名詞復數/不可數名詞”。
