　　參考答案：

　　1.正確答案(an)：D答案(an)解析：表示“數(shu)(shu)百”、“數(shu)(shu)千(qian)”、“數(shu)(shu)百萬”等不確切數(shu)(shu)目時，要用hundreds / thousands / millions of結(jie)構表示。D中hundreds of times意(yi)思是“數(shu)(shu)百倍”。答案(an)為D.

　　2.正確答案：A答案解析：the earth is round是客觀真理(li)，所以不(bu)管句(ju)(ju)子其(qi)它(ta)部分用什么(me)時態，這(zhe)個句(ju)(ju)子都用一般現在時。

　　3.正(zheng)確答案：D答案解析：根(gen)據句(ju)意可知應該用完成時，所以(yi)A答案錯誤。have been…表示(shi)狀態，可以(yi)和(he)表示(shi)一段時間(jian)(jian)的短語連用。have made和(he)have become都是(shi)瞬間(jian)(jian)動詞，不能和(he)表示(shi)一段時間(jian)(jian)的短語連用。

　　4.正確答案(an)：C答案(an)解析：taste是系動詞，taste nice構成系表結構，不用被動語態(tai)。但第二個空格(ge)處應(ying)該用被動語態(tai)，因為hamburgers與sell out之間是被動的關系。所以答案(an)是C.

　　5.正確(que)答案：B答案解析(xi)：such可(ke)以修飾可(ke)數(shu)(shu)名(ming)詞(ci)(ci)(ci)(ci)單復(fu)數(shu)(shu)和(he)不可(ke)數(shu)(shu)名(ming)詞(ci)(ci)(ci)(ci)，名(ming)詞(ci)(ci)(ci)(ci)前可(ke)以有形容(rong)詞(ci)(ci)(ci)(ci)作定語，其結構是“such +a/an+形容(rong)詞(ci)(ci)(ci)(ci)+可(ke)數(shu)(shu)名(ming)詞(ci)(ci)(ci)(ci)單數(shu)(shu)”，“such+形容(rong)詞(ci)(ci)(ci)(ci)+可(ke)數(shu)(shu)名(ming)詞(ci)(ci)(ci)(ci)復(fu)數(shu)(shu)/不可(ke)數(shu)(shu)名(ming)詞(ci)(ci)(ci)(ci)”。
