參考答案：
1.正確答案：D
答案解析：表示“數(shù)百”、“數(shù)千”、“數(shù)百萬(wàn)”等不確切數(shù)目時(shí)，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.
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(shí)態(tài)，這個(gè)句子都用一般現(xiàn)在時(shí)。
3.正確答案：D
答案解析：根據(jù)句意可知應(yīng)該用完成時(shí)，所以A答案錯(cuò)誤。have been…表示狀態(tài)，可以和表示一段時(shí)間的短語(yǔ)連用。have made和have become都是瞬間動(dòng)詞，不能和表示一段時(shí)間的短語(yǔ)連用。
4.正確答案：C
答案解析：taste是系動(dòng)詞，taste nice構(gòu)成系表結(jié)構(gòu)，不用被動(dòng)語(yǔ)態(tài)。但第二個(gè)空格處應(yīng)該用被動(dòng)語(yǔ)態(tài)，因?yàn)閔amburgers與sell out之間是被動(dòng)的關(guān)系。所以答案是C.
5.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(yǔ)，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”。
6.正確答案：B
答案解析：reflect on：思索，思考，有時(shí)表示“懷疑”。根據(jù)句意，應(yīng)該選reflect on.
7.正確答案：B
答案解析：due to是固定搭配，意思是：歸因于，由于。
8.正確答案：C
答案解析：本句中，what is accepted as true是主語(yǔ)從句，在句子中作主語(yǔ)。
9.正確答案：C
答案解析：keep sb doing sth：使某人持續(xù)做某事。
10.正確答案：B
答案解析：what在本句中引導(dǎo)do的賓語(yǔ)從句。
