61.正确答案：D答案解析：表示“数百”、“数千”、“数百万”等不确切数目时，要用hundreds / thousands / millions of结构表示。D中hundreds of times意思是“数百倍”。答案为D.

62.正确答案：A答案解析：the earth is round是客观真理，所以不管句子其它部分用什么时态，这个句子都用一般现在时。

63.正确答案：D答案解析：根据句意可知应该用完成时，所以A答案错误。have been…表示状态，可以和表示一段时间的短语连用。have made和have become都是瞬间动词，不能和表示一段时间的短语连用。

64.正确答案：C答案解析：taste是系动词，taste nice构成系表结构，不用被动语态。但第二个空格处应该用被动语态，因为hamburgers与sell out之间是被动的关系。所以答案是C.

65.正确答案：B答案解析：such可以修饰可数名词单复数和不可数名词，名词前可以有形容词作定语，其结构是“such +a/an+形容词+可数名词单数”，“such+形容词+可数名词复数/不可数名词”。

66.正确答案：B答案解析：reflect on：思索，思考，有时表示“怀疑”。根据句意，应该选reflect on.

67.正确答案：B答案解析：due to是固定搭配，意思是：归因于，由于。

68.正确答案：C答案解析：本句中，what is accepted as true是主语从句，在句子中作主语。

69.正确答案：C答案解析：keep sb doing sth：使某人持续做某事。

70.正确答案：B答案解析：what在本句中引导do的宾语从句。

71.正确答案：B答案解析：with用于与make contact搭配。本题使用的短语是make contact with sb.whom在本句中引导的句子做介词with的宾语。由于位于介词后面，所以用宾格形式whom.

72.正确答案：B答案解析：where在本句中引导表语从句。句意：这就是我们的不同之所在。

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

74.正确答案：A答案解析：本句是对现在的虚拟，所以条件状语从句用过去时。同时在虚拟语气中，一般不用was而一律用were，所以答案是A.

75.正确答案：A答案解析：本题的考点是：That引导的主语从句，注意that引导的主语从句在句中只起到连接作用，没有意义，也不做任何成分。

76.正确答案：A答案解析：doubt 用在肯定句中，之后的宾语从句用 whether 或 if 引导。用在否定句中，后接宾语从句用 that 引导。

77.正确答案：B答案解析：这里表示的是：来的方式，要用how.

78.正确答案：B答案解析：indifferent，形容词，“漠然的、冷淡的”，常用indifferent to.
