懂高中英语的人进
1 They always give the available seats to ______comes first.After all,the early bird catches the worm.A whom B who C whomever D whoever
2 I go to the supermarket _____three or four days .A each B all C every D both
3 Why are you still working on this project It's 4 o'clock in the afternoon and you're supposed it by noon.
A to finish B to be finishing C to have finished D To have been finishing
4 ___________not wait for him.We would rather we ____there without him.A better;went B Do;will go C Had better; went D Better ;should go
C C C A 请解释一下这样选的原因,
1.只要是来得早的人,他们就会提供可用座位,毕竟早起的鸟儿有虫吃.首先,前面有介词to,因此,排除B.D,再来看AC,whomever比whom的语气较强,根据语境,这里应该是说,无论是谁,只要来得早,他们就会提供座位,而且后面用了after all,看才出来语气较强烈,所以选C.
2.我每三四天去次超市,在表示频率时,只能用every.
3.为什么你还在做这个,都下午4点了,你应该在中午以前完成.be supposed to固定搭配,后面是by noon,是在中午以前完成,所以中午前就应该已经完成了,所以用完成时态.
4..最好不要等他了,我宁愿不和他一起要去那.do语气不对,had better单独是不对的,除非是we had better.后半句是would rather引导的虚拟语气,所以用过去式went.
