答案
71. A. 先行词gas被only修饰，关系代词要用that，而不用which。
72. B. through which引导定语从句，through which即through the hole,在定语从句中作状语。What引导的是see的宾语从句，并作从句的主语。
73. B. 为便于理解，改写本句
话：This is the school that some German friends visited last week. 不难看出，作表语的the school是先行词。that引导了定语从句，因为that同时又作visited的宾语，所以被省略了。其它选项结构不对。
74. A. 解释见35题。
75. C. 因为是two ballpens, 并且定语从句的谓语writes是单数概念。因此，C是正确选项。
76. B. 本句话中，主句的主语是all,为抽象概念。因此，其谓语应用单数的has been。关系代词that引导定语从句，并在从句中作主语。
77. 答案：C
解析：答案为C。本题是一个含蓄否定句，意思为：这种把钱用于预防疾病而不是治病的方式更好。此题中考查的是It’s adj to do sth.和make people better中的better的用法。better是good ,well的比较级。在此句中分别是表示更好，使人身体好或健康的意思。影响该题的解答主要在于理解rather than 后面这部分的意义。
78. 答案：C
解析：本题检查表示“除了”的英语表达方式，except for多加名词，except that 常加从句。本句翻译为：除了知道她来自北京以外，我对这位年轻的太太一无所知。答案是C。
79. 答案：B
解析：never be too careful表示“怎么小心也不为过”。enough修饰形容词要后置。Not与 too…to..句型连用常译为：非常，再…也不为过。
80. 答案：C
解析：一般情况下，主从句的反意疑问句的构成与主句相对应。此题属于这类，本题答案是C。该题容易误选为A，在 not think/ believe/ suppose/ imagine …+that clause构成的句式中，not是宾语从句的谓语动词，当主句的主语是第一人称时，转移到了主句谓语动词的前面。此时它的反意疑问句的构成应与从句一致，并注意否定词。此句如改为：“I didn’t think that he was good at mathematics,___”答案才能选A.
