1.I type as fast as (she),but not as accurately as (she).
在as...as...中,第一个as为副词,第二个as为连词.在as后连接人称代词,口语上通常用宾格me,him,her,us等.所以当人称代词后没有宾语时,主格,宾格均正确.
如：1).His brother is as handsome as he(him).
2).I play basketball as well as him(he does).
2.(Who is to blame) for the traffic accident that happened yesterday?
be to blame是一个固定短语,意思是“该受到责备”或“该负责任”.主动语态表被动.
3.（She is determined） not to let her parents down at all costs.
be determined to do something,意思是“下决心做某事”,
determined是一个形容词.
4.drop in 是一个动词词组,（口语）顺便到（某处）一下；偶然访问.
常用于：drop in on sb.或drop in at sp.
如：she droped in on me(at my house).
5.It was generous of him to lend his bicycle to me.
句中of表示性质,特征.译为拥有……的性质或特征.
It is +adj +of n +to do意思是“做……是……的”of后的名词为逻辑主语.
如：It"s very kind of you to help me.
It is + adj +for +n + to do意思是：“对……而言做某事是……的”
for 的宾语是to do 意义上的主语.
如：It is important for you to attend the meeting.
因为这个句子是对发生过的事情“借自行车”进行的陈述,所以用过去时.
