单项填空
31.C【解析】本题考查近义词辨析。sb.buy sth.for some money;sb.spend some money on sth.;sth.cost sb.some money，注意这三种固定搭配形式。
32.A【解析】本题考查情态动词的用法。need作情态动词用时，是need do sth./needn’t do sth.;need作实意动词用时，是need to do sth./not need to do sth.
33.A【解析】本题考查近义词辨析。anybody意为“任何人”;somebody意为“某人”;everybody意为“每个人，大家”。
34.C【解析】本题考查动词用法。keep sb.doing sth.意为“让某人一直做某事”。
35.C【解析】本题考查代词用法。its是形容词性物主代词，后面要有一个名词。上文提到“鸟”，下文表示“它的”，要用its。it指“它”，his指“他的”。
36.A【解析】本题考查主谓一致和固定搭配。twins是复数，be动词要用复数形式。表示“同样的”，要用the same，the不可少。
37.C【解析】本题考查and前后的动词时态一致。broke是过去式，所以fall也要用过去式fell。
38.B【解析】本题考查主从句时态一致。when引导的时问状语从句是一般过去时，若主句动词是短暂性动词，那么该动词也要用一般过去时。
39.A【解析】本题考查固定短语。make sb.do sth.意为“让某人做某事”，注意d0要用动词原形，前面不带to。
40.C【解析】本题考查动词时态。there was是过去式，so表示结果，所以空白处要用过去完成时，表示“过去的过去”。

42.B 【解析】本题考查介词。Can’t live without…意为“没有…不能活”。
43.B【解析】本题考查句子的部分倒装结构。当not…until置于句首时，句子要使用部分倒装，即将谓语的一部分如助动词或情态动词放在主语之前。如果句中的谓语没有助动词或情态动词，则需添加助动词d0，does或did，并将其置于主语之前。本句正常语序为：I didn’t realize how much time I had wasted until I began to work.
44.C【解析】本题考查过去时的被动语态。yesterday要求用过去式，被动语态的过去式是“was/were+过去分词”。
45.A【解析l本题考查连词。上半句“我妹妹只有五岁”，下半句“她游泳游得很好”，上下半句间是转折关系，所以用but。
