04. It made her happy ____ her son had been chosen to go to the Great Wall.
A. when B. because C. that D. for
参考答案：c
05. The salesman scolded the girl caught ____ and let her off.
A. to have stolen B. to be stealing C. to steal D. stealing
参考答案：d
从整体结构看，steal不是与scold存在时间对比意义而是直接修饰过去分词caught。这一部分句子可理解为The girl was caught when she was stealing. 即在现场被抓。
06. Why ____ you keep on troubling me with such questions while I’m busy?
A. could B. can C. must D. will
参考答案：c
本例中，must表示“偏偏”，常用于以you作主语的疑问句中。
07. ____ no point in refusing.
A. It seems B. There seems C. There seem D. It seemed
参考答案：b
这是there be存在句。point是句子真正主语，为了使句意显得更不确定并让语气委婉些，句中的主动词未用is而用seems。point是“用处、作用、理由”的意思，全句讲“似乎没有理由拒绝”。若用it作主语，这句宜改为It seems that there is no point in refusing.
08. The ____ candle in the room gave ____.
A. lighted, a poor light B. lit, a poor, light C. lighted, poor light D. lit, poor light
参考答案：a
选项中lighted和lit都是动词light的过去式和过去分词，但一般说来，lighted多作形容词修饰名词。若前面有副词修饰就可用lit，如： This is a brightly lit room. 这是一间灯光明亮的房间。 其次名词light作“光线”讲时，属不可数名词。但在其前用形容词修饰，将其具体化，如例句中的表达“为房间里点着的蜡烛光不足”，则应加上不定冠词构成a+adj.+light的形式，再如a strong light
