    參考答案：
    61.正確答案：D答案解析：表示“數(shù)百”、“數(shù)千”、“數(shù)百萬”等不確切數(shù)目時，要用hundreds / thousands / millions of結(jié)構(gòu)表示。D中hundreds of times意思是“數(shù)百倍”。答案為D.
    62.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(xiàn)在時。
    63.正確答案：D答案解析：根據(jù)句意可知應(yīng)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。
    64.正確答案：C答案解析：taste是系動詞，taste nice構(gòu)成系表結(jié)構(gòu)，不用被動語態(tài)。但第二個空格處應(yīng)該用被動語態(tài)，因為hamburgers與sell out之間是被動的關(guān)系。所以答案是C.
    65.正確答案：B答案解析：such可以修飾可數(shù)名詞單復(fù)數(shù)和不可數(shù)名詞，名詞前可以有形容詞作定語，其結(jié)構(gòu)是“such +a/an+形容詞+可數(shù)名詞單數(shù)”，“such+形容詞+可數(shù)名詞復(fù)數(shù)/不可數(shù)名詞”。
