where he was born的含义是"他出生的地点",而wherever he was born的含义是"不管他出生在哪儿"。

　　例5 The pilot asked all the passengers on board to remain __________ as the plane was making a landing.

　　A.seat

　　B.seating

　　C.seated

　　D.to be seating 

　　思路解析：该题考查过去分词的用法。remain为系动词,后面不接动词原形,排除A;seat 为及物动词,意为"使......坐",当表示"坐着"时,不能用seating,排除B和D。

　　答案：C 

　　黑色陷阱：本题有两处陷阱：一是受汉语影响,以为"乘客坐着"为主动意义,而忽略了seat的特点,误选B或D;二是忽视remain为系动词,误选A。

　　绿色通道：要做好此类题,在系动词后面要用过去分词作表语的有seat,locate,dress,lose,devote,hide等,平时加强记忆,解题时遇到这些词要多加注意。

　　A.Freed B.Freeing

　　C.To free D.Having freed

　　思路解析：本题考查现在分词的完成式。the students与free之间存在被动关系,排除A项。

　　黑色陷阱：本题有三处陷阱：一是误以为free与we之间存在被动关系,误选A;二是以为此处为目的状语,误选C;三是对于free与主句的动作先后没有判断出来,误选B。

　　绿色通道：要做对此类题,必须要判断出作状语的动词与主句主语的关系是主动还是被动,还要知道该动词与主句谓语动词的先后关系。如:Having finished the work,we went home.

　　2.Hellen,__________ here-everybody else,stay where you are.

　　思路解析：根据句子结构可判断这是祈使句，所以要用动词原形开头。祈使句表示命令、要求、请求或劝告等。祈使句一般以动词原形开头，无时态及数的变化，句末用句号或感叹号。答案：A 

　　黑色陷阱：本题有两处陷阱：一是忽略破折号"-"的作用,不能判断出前面是一个完成的句子,误选C或D项;二是没注意Hellen后的逗号","以为Hellen是句子的主语,而不是称呼语,误选B。

　　绿色通道：要做对此类题,必须注意破折号"-"和逗号","的作用。如:Tom,don't be late next time.汤姆,下次不要迟到。
