1.A.四个词里只有far可以修饰比较级.
2.D.一般同时出现could和was/were able to的时候,答案总是选后者.could表示过去的能力,而后者更强调过去成功的做成了某事.注意,be able to只有过去时时候能这样用,如果是其他时态,都可以和can互换.
3.C.when引导的时间状语从句,主句过去进行时,从句一般过去时.
4.B.按照比例增加减少,介词用by.
5.D.因为这句话中已经有enter这个谓语动词了,所以B和C都首先排除（took也是谓语动词）,instead of是代替的意思.
6.A.表示一盏灯被挂在哪里.B意思是绞死.C缺少谓语动词,D主动被动错.
7.D.动词不定式往往用来做表语.
8.A.used to do sth,意思是过去常常做什么事情.be used to sth.习惯了什么事情.
