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”。

66.正確答案：B答案解析：reflect on：思索，思考，有時表示“懷疑”。根據(jù)句意，應(yīng)該選reflect on.

67.正確答案：B答案解析：due to是固定搭配，意思是：歸因于，由于。

68.正確答案：C答案解析：本句中，what is accepted as true是主語從句，在句子中作主語。

69.正確答案：C答案解析：keep sb doing sth：使某人持續(xù)做某事。

70.正確答案：B答案解析：what在本句中引導(dǎo)do的賓語從句。

71.正確答案：B答案解析：with用于與make contact搭配。本題使用的短語是make contact with sb.whom在本句中引導(dǎo)的句子做介詞with的賓語。由于位于介詞后面，所以用賓格形式whom.

72.正確答案：B答案解析：where在本句中引導(dǎo)表語從句。句意：這就是我們的不同之所在。

73.正確答案：A答案解析：isolate sb/sth from sb/sth是固定搭配。

74.正確答案：A答案解析：本句是對現(xiàn)在的虛擬，所以條件狀語從句用過去時。同時在虛擬語氣中，一般不用was而一律用were，所以答案是A.

75.正確答案：A答案解析：本題的考點(diǎn)是：That引導(dǎo)的主語從句，注意that引導(dǎo)的主語從句在句中只起到連接作用，沒有意義，也不做任何成分。

76.正確答案：A答案解析：doubt 用在肯定句中，之后的賓語從句用 whether 或 if 引導(dǎo)。用在否定句中，后接賓語從句用 that 引導(dǎo)。

77.正確答案：B答案解析：這里表示的是：來的方式，要用how.

78.正確答案：B答案解析：indifferent，形容詞，“漠然的、冷淡的”，常用indifferent to.

79.正確答案：B答案解析：本題考查詞義辨析。arrive at：獲得(結(jié)果);達(dá)到(目的)。

80.正確答案：B答案解析：出生在某地，要用介詞in.此句話中，in which=where.
