参考答案：
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”。
