参考答案及试题解析
1.Does have
【解析】句意:她必须吃些药。原句是一般现在时,主语she是第三人称单数,改为一般疑问句时,需在句首添加助动词Does,并将has还原为原形have。
2.Did watch Yes she did
【解析】句意:她昨天看了一部动画片。原句是一般过去时,谓语动词watched是实义动词,改为一般疑问句时,需要在句首添加助动词Did,并将实义动词变回原形watch。肯定回答格式为:Yes, 主语+did,此句主语是she,所以回答是Yes, she did。
3.needn’t wear
【解析】句意:你在公共场合必须戴口罩。原句中“must”是关键词,表示“必须”,改为否定句时为“needn’t”,表示“不必”,后直接接动词原形“wear”,表示“不必戴”。
4.Avoid doing
【解析】句意:我们应该避免危险的事物。原句中“should avoid”表明句子表达的是一种建议或应该做的事情,改为祈使句时,祈使句通常以动词原形开头,直接表达命令、请求或建议等语气,所以去掉“should”,直接用动词原形“avoid”,同时“avoid”后面接动词时要用动名词形式,所以“avoid”后面跟“doing”,句首注意首字母大写。
5.will meet
【解析】句意:志愿者们经常在中心集合。用tomorrow改写句子,时态要变为一般将来时,结构为will+动词原形,meet意为“遇见,集合”。
6.doesn’t have
【解析】句意:他喉咙痛。has为实义动词,主语He是第三人称单数,改否定句需借助助动词doesn’t,且助动词后动词要还原为原形have。
7.is/isn’t nothing/anything
【解析】句意:我的洗衣机出故障了。将其改为否定句时,既可以使用“is nothing”,表示否定意义的单词是nothing。也可以使用其等价结构“isn’t anything”。anything用于否定句。两者在句中均表示“没有什么故障”。
8.Will help
【解析】句意:他们这周末会帮助老人。原句为一般将来时的陈述句,改为一般疑问句时,将助动词Will提到句首且大写,后接主语they和动词原形help。
9.listens to himself his
【解析】句意:我们在空闲时间听音乐来放松自己。原句是一般现在时,主语He是第三人称单数,listen to变三单形式listens to;反身代词ourselves(我们自己)要对应改成he的反身代词himself(他自己);物主代词our(我们的)对应改成he的形容词性物主代词his(他的)。
10.shouldn’t
【解析】句意:你应该少花点时间在电脑游戏上。改为否定句,应该把“should”改为“shouldn’t”。故填shouldn’t。
11.Does join does
【解析】句意:琳达每周五都会参加国际象棋俱乐部的活动。原句含有实义动词joins且是一般现在时,改为一般疑问句,需借助助动词does,接动词原形join;肯定回答要和疑问句的助动词保持一致,所以用does。故填Does;join;does。
12.doesn’t practice
【解析】句意:她每天练习吉他一小时。根据“practices”可知,该句为一般现在时,practice为实义动词,改为否定句时,主语为She,助动词应用does,后加not,缩写成doesn’t,后加动词原形。故填doesn’t;practice。
13.didn’t ride
【解析】句意:男孩们昨天沿着河边骑自行车。原句为一般过去时,实义动词为rode,变否定句需借助助动词did的否定形式didn’t,rode变回原形ride。故填didn’t;ride。
14.is relaxing
【解析】句意:他通过看电影来放松自己。现在进行时的结构是“be + 动词-ing形式”,主语是He,对应的 be动词用is。原句谓语动词是relaxes,它的现在分词形式是relaxing。
15.can’t play
【解析】句意:放学后他们可以在公园里打篮球。原句含有情态动词can,改为否定句需在can后加not,构成can’t,接动词原形play。
16.should not
【解析】句意:我们应该在学习和玩耍之间保持平衡。改为否定句,直接在情态动词should后加not,即should not。
17.It’s to
【解析】句意:我发现听音乐很容易放松。find it+形容词+to do sth.=It’s+形容词+for sb.+to do sth.表示“做某事对某人来说是……的”。固定句型开头必须用It作形式主语,句子是一般现在时,所以用It’s=It is,后面真正的主语要用to do形式,故填It’s;to。
18.goes traveling
【解析】句意:他们周末去旅行。原句是一般现在时,句子结构为“主语+动词短语 (go traveling)+时间状语 (on weekends)”。当把主语由第三人称复数“they”改为第三人称单数“he”时,根据一般现在时中,当主语是第三人称单数时,谓语动词要用第三人称单数形式这一语法规则,动词go要变为goes;而go traveling是固定短语,表示“去旅行”,此处用“goes traveling”,空格处用“goes”和“traveling”。
19.Do like
【解析】句意:我喜欢放学后和我的朋友们聊天。原句是一般现在时,谓语是实义动词like,原主语是第一人称I,改疑问句后主语变为第二人称you,需要在句首加对应助动词Do,注意首字母大写;助动词后谓语动词必须用原形,所以用原形like。

25.How strong
【解析】句意:原句意为“他腿上的疼痛很强烈”,改为感叹句时,需用“How+形容词”的结构来强调“strong(强烈的)”这一特征,符合感叹句的句式要求。故填①How;②strong。

【解析】句意:保持健康的生活方式很重要。important“重要的”,形容词,是中心词,用how引导感叹句,结构为“How+形容词+主语+谓语!”。
27.make it
【解析】句意:她帮助我。我能完成这项工作。根据句子结构可知,合并为一句后,句子结构为“主语+谓语+宾语+宾语补足语”,使用“make it+形容词+to do sth.”结构,表示“使做某事……”,it是形式宾语,动词不定式是真正的宾语,形容词作宾语补足语。故填make;it。
28.didn’t give
【解析】句意:他们赠送了一些书。原句中gave是动词give的一般过去式,改为否定句时,需借助助动词did的否定形式didn’t,且助动词后要跟动词原形give;同时肯定句中的some,在否定句中要变为any。
29.Would

【解析】句意:我们昨天在课堂上讨论了自然奇观。原句中“discussed”意为“讨论”,其同义短语为“talk over”;句子时态为一般过去时,所以“talk”要变为过去式“talked”。
67.the largest
【解析】句意:上海是中国一座很大的城市。题目要求将原句改为最高级,large的最高级是largest,形容词最高级前要加定冠词the。故填the;largest。
68.is not
【解析】句意:在我看来,大堡礁值得一游。改为否定句,句中有be动词is,直接在is后加not构成否定形式。
69.People said the mountain was too high for birds to reach it.
【解析】原句“so...that...”表示“如此……以至于……”,“too...to...”表示“太……而不能……”,二者可以相互转换。原句中“even birds could not reach it”表示“甚至鸟儿都不能到达它”,改写时用“too...to...”结构,即“the mountain was too high for birds to reach it”,其中“for birds”表示“对于鸟儿来说” 。故填People said the mountain was too high for birds to reach it.
70.Pack your bags and pay a visit with your family if you are free!/If you are free, pack your bags and pay a visit with your family!
【解析】句意:如果你有空,你可以收拾行李和家人一起去参观。改为祈使句时,去掉情态动词can,将动词原形pack置于句首,首字母大写,其余部分保持不变,句末可用感叹号或句号。if条件状语从句可置于句首或句末。故填Pack your bags and pay a visit with your family if you are free!或If you are free, pack your bags and pay a visit with your family!
71.waterfalls they’re
【解析】句意:我喜欢瀑布,因为它非常有气势。要将句子改为复数形式,需要将单数名词a waterfall变为复数waterfalls,同时将指代它的代词it和系动词is相应地变为they和are,此处需用缩写形式they’re。故填waterfalls;they’re。
72.Does cover
【解析】句意:海洋覆盖了地球表面的大部分。原句为肯定句,谓语动词是covers(第三人称单数形式),改为一般疑问句时,需借助助动词does,并将其放在句首,同时原句中的谓语动词covers要还原为原形cover,其他部分保持不变。故填Does;cover。
73.Are they are
【解析】句意:这些蔬菜非常新鲜。原句是主系表结构的陈述句。改为一般疑问句时,需将be动词“are”提前至句首,首字母大写,其余部分保持不变。作肯定回答时,用“Yes, 主语+be动词”的结构,原句主语“the vegetables”为复数,用代词“they”代替,be动词仍用“are”,故填Are;they;are。
74.is known
【解析】句意:这条瀑布以其强大的水流而闻名。改为被动语态,应用短语“be known for”替换“be famous for”,意为“因……而闻名”;句子时态为一般现在时,主语是The waterfall,be动词应用is。故填is;known。
75.the most outgoing
【解析】句意:她的弟弟非常外向。原句是一般现在时的陈述句,需要用in his class改写为含最高级的句子。形容词outgoing是多音节词,其最高级形式为the most outgoing,用来表示“在他的班里最外向”。故填the;most;outgoing。
76.she had her
【解析】句意:她说:“我已经完成了对亚马逊雨林的研究。”变为间接引语时,从句时态要与主句保持一致,需将原句子的现在完成时变为过去完成时,其结构为“had+过去分词”,主语为she;第二空修饰名词research,用形容词性物主代词her“她的”。故填she;had;her。
77.Had learned
【解析】句意:汤姆在旅行之前就已经了解过大堡礁了。句子为过去完成时,改为一般疑问句,需要把助动词had提到句首,并且首字母需要大写,动词过去分词learned保持不变。故填Had;learned。
78.what should
【解析】句意:我不知道。我们应该采取什么措施来减少台风造成的损害?要将它们合并为宾语从句,需将第二个句子“What measures should we take to reduce the damage caused by typhoons ”作为第一个句子“I don’t know”的宾语。在宾语从句中,语序要使用陈述句语序,即将特殊疑问句中的疑问语序“should we”调整为陈述语序“we should”,其他部分保持不变。故填what;should。
79.would take
【解析】句意:他说:“明年我会参加自然奇观国际会议。”改为间接引语时,原句的一般将来时“will participate”要随主句的过去时“said”变为过去将来时“would take”,“participate in”对应同义短语“take part in”。故填would;take。
80.what leads
【解析】句意:你知道吗?是什么导致了该地区独特石柱的形成?原句“What leads to the formation of the unique stone pillars in this area ”是特殊疑问句,疑问词what在从句中作主语,语序本身就是“主语+谓语”的陈述语序,故直接放在know后面作宾语。从句主语是what,谓语动词用第三人称单数形式leads。故填what;leads。
