单选题 A. please
B. pleased
C. pleasing
D. to please
【正确答案】 B
【答案解析】中级问题 very在这里属于修饰成分，可以把它去掉。空格前有be动词，be动词不是接现在分 词，就是接过去分词。please作为动词使用的时候是及物动词，当它后面没有宾语的时候就应使 用被动语态。be pleased to do意为“很乐意做某事”。
单选题 A. In addition
B. As well as
C. Unless
D. Given
【正确答案】 A
【答案解析】中级问题 句子的开头就是空格，而后面有逗号，那么这里应当填入副词。B选项是连词，unless 是引导状语从句的连词；given有可能是形容词、介词、连词。正确答案只能是A选项。“介词+ 名词”可以有副词的作用。in addition是“另外”的意思。
单选题 A. considering
B. consideration
C. considerate
D. consider
【正确答案】 D
【答案解析】高级问题必须知道这里的I beg后面省略了that。连词that在引导名词从句的时候经常被省略。 怎么才能知道这里省略了that呢?如果从语法上一点点地解释的话，恐怕书就会变得太厚，就 得花大家更多的钱了。呵呵!与此相比，记住I beg(that)这个句式不是更方便吗?连词that的 后面应使用“主语+谓语动词”。
