使用定语从句,将下列两个句子合并成一句

1。She lost an English book whose cover is dark blue。
2。He has a penfriend whom he has never seen。
3。This is the way of life which she is looking forward to。
1。去掉it,这句话是定语从句,完整的应该是She moved to an old house which/that her parents left to her。定语从句中当关系代词在从句中作宾语时,可以省略。
2。help变为helps。定语从句中who指代的是the girl,所以从句中的谓语动词应该用单三。
3。变what为that,或者将all去掉。all that就等于what。
可以保证百分之百的正确率~
