(改为否定句) You drink water. 【答案】 shouldn’t any 【详解】句意：你应该喝一些水。原句中should是情态动词，改为否定句时，直接在should后加not，缩写为shouldn’t；同时否定句中some要改为any。故填shouldn’t；any。 42．你英语不太擅长，应该多花些时间来读英语。 You’re not good at English, you English. 【答案】should spend more time reading 【详解】应该should，用于提建议，后接原形动词；多花些时间做某事spend more time doing sth.；读英语read English。故填should spend more time reading。 43．Peter should give up his bad living habits. （改为一般疑问句）       Peter up his bad living habits? 【答案】 Should give 【详解】句意：彼得应该改掉他的不良生活习惯。原句含有情态动词，疑问句把情态动词提到主语前，后接动词原形，故填Should；give。 44．——你明天能来参加我的聚会吗？ ——可以，我很乐意。 — to my party tomorrow? —Yes, I’d love to. 【答案】 Could you please come 【详解】根据中英文对照可知，情态动词could“能”表示委婉的请求；you“你”；please“请”，礼貌用语；come to“来到”。故填Could；you；please；come。 45．你把房间打扫一下好吗？ you the room? 【答案】 Could please clean 【详解】此处表示委婉的请求，用句型Could you please do sth?“你能做……好吗”；clean“打扫”。故填Could；please；clean。 46．Please feel free to eat some fruit, children. （改为同义句） Please help some fruit, children. 【答案】 yourselves to 【详解】句意：孩子们，请随意吃些水果。要改为同义句，feel free to do sth.“随意做某事”可转换为短语help oneself to sth.“随便吃/用某物”，结合宾语children（复数），反身代词用yourselves。故填yourselves；to。 47．你必须相信自己，才能克服这个困难。 You have to in to overcome this difficulty. 【答案】 believe yourself 【详解】根据中英文对照可知，此处缺少“相信自己”。believe in oneself“相信自己”，主语You对应的反身代词是yourself“你自己”，have to后接动词原形。故填believe；yourself。 48．不要总是将你自己与他人相比。 Don’t always others. 【答案】 compare yourself with 【详解】compare ... with“把……和……相比”，Don’t后跟动词原形；yourself“你自己”。故填compare；yourself；with。 49．令他们惊讶的是，他们不能清晰地表达他们自己。 , they can’t . 【答案】 To their surprise express themselves clearly 【详解】根据中英文对照可知，第一空意为“令他们惊讶的是”，短语“to one’s surprise”表示“令某人惊讶的是”，这里“他们”对应的形容词性物主代词是“their”，且位于句首，首字母大写，所以第一空填To their surprise；第二空意为“清晰地表达他们自己”，“表达”用动词“express”（“can’t”后接动词原形），“他们自己”是反身代词“themselves”，“清晰地”是副词“clearly”（置于句尾，修饰动词“express”），所以第二空填express themselves clearly。故填To their surprise；express themselves clearly。 50．They had a good time in Beijing. (改为同义句) They in Beijing. 【答案】 enjoyed themselves 【详解】根据句意可知，原句表示“他们在北京玩得很开心”，需要改写的部分是“had a good time”，其含义为“玩得开心”。在英语中，“玩得开心”还可以用“enjoy oneself”这一短语来表达。由于主语是“They”，所以反身代词应该用“themselves”。又因为原句时态为一般过去时，所以改写后的句子时态也应保持一致，即“enjoy”应变为过去式“enjoyed”。故填enjoyed；themselves。 试卷第1页，共3页 试卷第1页，共3页 学科网（北京）股份有限公司 $
