D. orbiting

解析：答案选D.本题考查现在分词做状语。动词orbit和主语the satellite是主动关系，主动关系的话要选现在分词做状语，所以排除B和C;然后看A和D,A

是完成式，只有在主句是过去时的时候，状语中的非谓语动词才要用分词的完成式。

D. wanting not

解析：and 前后连接的两个句子结构平行，所以realize 应该和want 一样使

用现在分词形式。而且分词的否定是在前面+not 所以选C。

A. throwing

B. being thrown

C. having thrown

解析：考察的是see sb doing吉构以及被动语态a rope ladder是被认出来的所以排除AC。因为绳梯被认出来与三个男人在攀爬时间几乎一致，因此选

B。

A. being delivered

B. was delivered

C. be delivered

D. having been delivered 解析：考察独立主格，演讲先吉束，

9. Agriculture is the country s chief source of wealth, wheat ____ b y far the biggest cereal crop.

A. is

B. been

C. be

D. Being

解析：因为前半句Agriculture is the country s chief source of wealth已经是个完整的句子，而后面又没有连词，所以不可能再出现动词，排除A和C,而B没有这种用法，正确的独立主格表示完成时的结构应该是having been 所以B错。

的，所以用表示主动关系的ING 形式，不用表示过去、完成的made。
