高一英语1)When we were having maths class,the door opened and in
1.选B.in came a stranger是倒装句,原句应是a stranger came in.倒装是为了强调.这句话应该怎么理解呢?当我们上数学课的时候,门开了,进来一位陌生人,他搅了我们的课.interrupting 表示伴随,指陌生人在进来的同时,搅了我们的课.
2.选D.这句话的意思是:你知道他为了在学校照顾四个孩子孩子所面对的困难吗?
to keep表目的.这句话主要的成分为:Do you know his difficulity
he had 作difficulty的定语,to keep… 是非谓语,作目的状语.
3.选D.动名词短语作主语,排除A、B.what to do 固定的.
