1,不必
she asked:"Do you have some apples?"
变为
she asked me if i have some apples.
2.
先行词是my home 还原回去是we could take good care of him in my home.
定语从句先行词作地点状语
目的状语从句也可以,但是选项中没有so that或in order that
3
experiments这里表示抽象的地点还原回去是scientists develop and test new medicines in these expriments
类似表示抽象地点的还有situstion,stage,point等
4.
这个是强调句型中又包含一个定语从句
It was in the very house ( )was built of stone( )he spent his childhood.
第一个空是定语从句,先行词前有the very那么只能用that
第二个空是it is..that强调句型
5.
could常用于问句表示委婉
但是回答是必须是can而不能使could
6.
B.might are killed 表示对现在的推测,而且是被动形式
D.may have killed是对过去的推测,是主动形式
b不可能对情态动词后必须是动词原形,怎么可能是are,be还差不多
好辛苦
