试题答案与解析


1． C)【句意】人们对他的童年了解得很少，只知道他早在10岁就在工厂里工作。

【难点】此处save为介词，相当于except，但不太通俗，其后除接名词或代词外，也可接that 引导的从句。

2． C)【句意】董事会的成员一致认为主要的精力应该放在为取得最高利润而做的努力上面。

【难点】understanding 如同suggestion, motion, plan, idea, order等词一样，其后的同位语从句中的谓语动词须用虚拟语气，should加原形动词或直接用原形动词。

3． B)【句意】他们发现为可能遇到的最差的条件做准备是不值得的。

【难点】在find it worthwhile to prepare …中，find之后是一个复合结构，其中it是形式宾语，真正的宾语是to prepare, worthwhile （值得花时间的）是宾语补足语。

4． C)【句意】在短道上，四分之一英里赛马比其它品种的马起动要快，转弯要急，跑得也更快。

【难点】than other breeds can 是一个比较状语从句，与前边的more quickly， more sharply， faster 等相呼应。A)，D)本身是错的，B)无比较意思。

5． B)【句意】多数保险代理人宁愿你在他们调查了情况之后才提出申诉。

【难点】would rather 后跟的从句用动词过去时，表示“宁愿别人…”，而C)和D)无实义动词，故B)是正确的。
