Though it was a bit expensive, I think it was reasonable. st选C(用PAY不可以吗) 3.----I ’d like to buy a good camera. ----Well, we have several models ______. pickup选B(不是有I HAVE MUCH HOMEWORK TO DO 的结构吗) 4.21. The colors of that coat and hat don’t _______. ch选A 5.22. ----Can you tell me how to learn English well? ----Do more reading, _______you’ll be good at spoken English. dD.until选C(THEN怎么不行?)
1.是have sb do sth形式，意思是让某人做某事，而不是现在完成时。 2.如果是pay的话应该是pay 500 yuan for the bike 3.其实是choose a good camera from several modals。所以介词不能省略。 tch有匹配般配的意思，fit 是只大小的不合适。 5.这是固定搭配，前面是一个祈使句+and/or引导的从句，表示那么/否则
