1. _____ all the inventions have in common is ______ they have succeeded.
A.What; what
B.That; what
C.What; that
D.That; that
答案:C
答案解析
第一空既是主语从句的(谓语have)宾语,又是主句的主语,所以应该填what;第二空用that来引导表语从句。由于they ahve succeeded是完整的一句话,故表语从句,可使用连接词that进行修饰。【译文】 所有发明共有的特点是他们成功了。【译文】 所有发明共有的特点是他们成功了。
2. I’ll give the prize to _______ finishes the work first.
A.whomever B.whoever C.who D.anyone
答案:B
答案解析
试题分析:考查宾语从句。本句中whoever引导宾语从句whoever finishes the work first。Whoever在句中做主语,并引导起该宾语从句。A项只能在句中做宾语,anyone只可以做主语,但是不能引导宾语从句。句意:我会把奖发给最先完成工作的人。Who的语气没有whoever强烈。故A正确。名词性从句中的“救从不救主原则”和“首选原则”。【译文】 我将把奖品给最先完成工作的人。
3. It was five o’clock in the afternoon _____ they climbed up to the top of the mountain.
A.since B.when C.That D.until
答案:B
答案解析
此句为一主从复合句。"when"引导定语从句;若看作强调结构,应在five前加at。【译文】 他们爬上山顶的时候是下午5点钟。
4. Last term our maths teacher set so difficult an examination problem _____ none of us worked out.
A.that B.as C.so that D.which
答案:B
答案解析
as引导定语从句修饰"examination problem",在从句中作宾语,因其先行词前有限定词so。若看作"so…that…"结构,结果状语从句应加宾语,为"worked it out"。【译文】 上学期数学老师考试出题太难,没有一个人能解出来。
5. -My mathematics is very poor. -Don’t worry. I’ll help you ______ I can.
A.as far as B.as soon as C.as quickly as D.as possible as
答案:A
答案解析
as far as:就……;到……程度,表范围。D项应为as…as possible。【译文】 --我的数学很差。 --不要着急。我将尽力帮助你。
