请从以下四个选项里挑出最符合题意的一个选项：
_____ the door when a gust of wind blew the candle out.
A. He had no sooner opened
B. Hardly had he opened
C. Scarcely did he opened
D. No sooner did he open
参考答案：B. Hardly had he opened
解析：这一题的考点是一个表示瞬间时的搭配。如选项中hardly/scarcely…when或no sooner…than的搭配，这些则为固定搭配，意思是“一…就…”。含有此结构的句子，表示从句中的动作一发生，主句中的动作随即发生。当hardly/scarcely或no sooner置于句首时，从句的主语和谓语必须倒装。在这一个句子结构中，主句一般用过去完成时，从句一般用一般过去时。由此可知正确答案为B. Hardly had he opened。
请从以下四个选项中选出最符合题意的一个选项：
Despite the fact that the area had been hit by the severest drought in twenty years, a(n)____ harvest was gathered in.
A. desirable
B. wishful
C. bumper
D. ideal
参考答案：C.bumper
解析：从结构上来看，这一题是一个让步从句+主句。因此，the severest drought所意指的结果要与空格里的词是反义的——xx harvest。也就是说，该地经历了最为严重的干旱，可是仍然“丰收”了。从四个选项里来看，表示“丰收”的词也只有bumper了。英文解释是A bumper crop or harvest is one that is larger than usual.
请从以下四个选项里挑出最符合题意的一个选项：
The factory has turned out ________.
A. twice TV sets this year more than last year.
B. TV sets this year as many as last year.
C. twice as many TV sets this year as last year.
D. TV sets twice more this year than last year.
参考答案：C. twice as many TV sets this year as last year.
解析：这一下考点似乎是有关于twice的用法，实则是有关于倍数的句型。我们先来看看twice的意思。Twice在这一个句子里，是为作为副词来使用的，其意思是“两倍; 强(或好、难)得多”，即If one thing is, for example, twice as big or old as another, the first thing is two times as big or old as the second. People sometimes say that one thing is twice as good or hard as another when they want to emphasize that the first thing is much better or harder than the second. 也就是说，两个事物比较的话，前者是后者的“两倍”，但后接的不是than，而是as +adj.+as。例如：The figure of seventy-million pounds was twice as big as expected. /7,000 万英镑的金额是预期的两倍。这是一种表示倍数的方式，而另外两种方式是：倍数 + 形容词比较级 + than ...和倍数 + the + size/length等名词 + of ..。
