1.C
句意:——那是一个不同寻常的一天。我们去郊游了,玩得很开心。——是的,我们期待下一次旅行。
a 一个(用于辅音音素前);the 这/那(特指);an 一个(用于元音音素前)。根据空后单词“unusual”是以元音音素开头,且表示泛指,应选 an。
2.C
句意:露西太喜欢把自己的生活和别人的作比较,以至于她总是情绪低落。
on在……上面;at在某处/时间;in在……里面/处于某种状态;with和……一起。根据固定搭配“in low spirits”意为“情绪低落、没精神”,应填in。
3.B
句意:我们注意到维苏威火山上空有一片很黑的云。很快那片云向下移动,覆盖了海面。
考查冠词用法。a一,泛指,用于辅音音素开头的单词前;an一,泛指,用于元音音素开头的单词前;the特指。第一空表示“一片很黑的云”,是首次提到且“cloud”以辅音音素开头,用不定冠词“a”;第二空再次提到前文已出现的“那片云”,用定冠词“the”。故选B。
4.B
句意:写作比赛很重要。你应该尽可能仔细地写。
考查as...as possible结构的用法和副词辨析。quickly快速地;carefully仔细地;more quickly更快地;more carefully更仔细地。as...as possible结构要求使用副词原级;根据句意“The writing competition is important”,可知强调写作质量而非速度,应选“仔细地”。故选B。
5.D
句意:没有人教这位老妇人怎样使用微信。她全都是自学的。
考查代词辨析。she她,人称代词主格;her她的/她,物主代词/人称代词宾格;hers她的,名词性物主代词;herself她自己,反身代词。根据“Nobody taught the old lady how to use WeChat”可知,没有人教她,所以是自己学习的。learn sth. by oneself“自学”符合语境。故选D。
6.D
句意:——为了改善当地居民的生活,政府在这里建立了一个体育中心和一个青年中心。——太棒了!人们有更多的地方可以玩了。
考查非谓语动词。根据“local people’s life, the government has built a sports centre and a youth centre here.”可知,政府建立体育中心和青年中心的目的是改善当地居民的生活,应用动词不定式作目的状语。故选D。
7.A
句意:你最好不要吃太多垃圾食品。它对健康有害。
考查情态动词后加动词原形。had better是情态动词,后接动词原形,其否定形式为had better not do sth表示“最好不要做某事”。故选A。
8.C
句意:男孩们有个好消息!下个月将有一场篮球赛。
考查there be句型的一般将来时。there be句型表示“某地有某物”,其一般将来时结构为“there is/are going to be”或“there will be”,不能用there have/has这种形式,主语“a basketball game”为单数,be动词用is。故选C。
9.B
句意:尽管他很累,他还是继续工作直到午夜来完成这个项目。
after在……之后;until直到……为止;unless除非;in在……里面。根据“continued working... midnight”可知,此处表示动作持续到某个具体时间点,until(直到……为止)符合语境。unless后接句子,in不与midnight搭配,after语义不符。
10.D
句意:她独自一人住在这所房子里,但她一点也不感到孤独。
考查形容词及副词的用法。lonely孤独的(形容词);alone单独(副词/形容词)。根据“lives”可知,第一空应该填副词alone修饰动词,表示独自一人住;根据“feel”可知,第二空填形容词lonely作表语,表示不感到孤独,故选D。
11.B
句意:我建议她每天早上不要花太多时间挑选穿什么衣服。
考查动词不定式的否定形式。advise sb. not to do sth.是固定搭配,表示“建议某人不要做某事”。动词不定式的否定形式是在to前加not,即not to do。故选B。
12.B
句意:你做得很好!我们为你感到骄傲。
be kind to对……友好;be proud of为……感到骄傲;be angry with对……生气。根据前句“You did a great job!”可知是表扬,应选用表示“为……感到骄傲”的短语;主语是“We”,be动词应用are。
13.A
句意:——你多久打扫一次你的房间?——一周一次。我认为保持整洁很重要。
考查副词短语。Once a week一周一次;In a week一周后;For a week持续一周;A week ago一周前。问句中的How often是对动作发生频率进行提问,此处需要回答打扫房间的频率,“Once a week”表示“一周一次”,直接回答频率。故选A。
14.B
句意:冰箱里没有苹果了。我们去买一些吧。
考查不定代词辨析。some一些,通常用于肯定句;any任何,一些,通常用于否定句和疑问句;much许多,修饰不可数名词;few几乎没有,修饰可数名词复数。根据“There aren’t...apples in the fridge.”可知,此句为否定句,且“apples”为可数名词复数,因此应用any来修饰。故选B。
15.D
句意:——你为什么还在生莉莉的气?——她故意打碎了我的眼镜。所以她的道歉对我来说毫无意义。
by accident偶然地;in the future未来;from time to time不时;on purpose故意;根据“Why are you still so angry with Lily?”可知说话人仍在生气,结合“So her apology counted for nothing to me.”可知道歉无效,说明对方打碎眼镜的行为是有意为之,而非意外。此处需要填入表示“故意地”含义的短语,on purpose符合语境。
16.C
句意:——鲍勃,一点阳光对我们有好处,还能让我们开心。我们出去散步吧。——我很想去,但我今天有点累。明天怎么样?
考查形容词短语和副词短语。a bit of后接不可数名词,sunshine是不可数名词,第一空用a bit of;a bit后接形容词或副词,tired是形容词,第二空用a bit。故选C。
17.A
句意:游泳池的深度是2米,所以孩子在这里游泳很危险。
depth深度;height高度;length长度。根据“2 meters”及“dangerous for kids”可知,2米对于孩子来说太深了,因此危险,此处指水的深度,故选A。
18.B
句意:——你最近看起来精力充沛。——我每天坚持锻炼以保持良好的状态。
description描述;condition状况,状态;preparation准备。根据“You look energetic”和“keep exercising”可知,锻炼是为了保持良好的身体状况,固定搭配in good condition意为“状态良好”。
19.C
句意:——我想知道这所新学校是否漂亮。——你可以问问你的兄长。他和你上同一所学校。
believe相信;know知道;wonder想知道。根据回答“You may ask your elder brother.”可知,说话人目前不确定新学校的情况,需要去询问,wonder表示“想知道”,符合语境。
20.A
句意:开车几个小时后,他们发现自己身处一片广阔、寂静的沙漠之中,周围没有生命迹象。
desert沙漠;earth地球;ocean海洋。根据“driving”可知是在陆地上行驶,排除ocean;再结合“vast, silent”和“no sign of life around”可知周围荒无人烟,符合沙漠的特征。
21.C
句意:哈尔滨是如此美丽的一座城市,以至于每年都有成千上万的人去参观它。
such如此(修饰名词);so如此(修饰形容词/副词);thousand千;thousands of成千上万的。根据“a beautiful city”可知第一空应用such。thousand前有具体数字时用单数,与of连用表示概数时用复数形式thousands of。根据句意表示不确定数目“成千上万”,第二空应用thousands of。
22.C
句意:——我认为在大考前感到有点紧张是正常的。我们只需要保持冷静,尽最大努力。——你说得对。面对恐惧是变得更强的一部分。
difficult困难的;strange奇怪的;natural自然的。根据语境可知,大考前感到紧张是一种普遍的心理反应,结合后文建议保持冷静及答语“面对恐惧是成长的一部分”可知,此处指这是自然且正常的现象,无需过度担忧。应填natural。
23.C
句意:——爸爸,我今晚可以单独去见我的网友吗?——不行。这对你的安全来说是一个很大的风险。
chance机会;treat款待;risk风险。根据网络安全常识,单独见网友存在安全隐患,risk符合语境。
24.B
句意:——你怎么读数字40,391?——它读作forty thousand, three hundred and ninety-one (四万零三百九十一)。
英语中hundred, thousand等词前有具体数字修饰时不用复数形式,排除A;百位与十位之间用and连接,千位与百位之间通常不用and,排除C。故选B。
25.B
句意:太阳岛位于松花江畔的松北区。
location位置(名词);is located位于;located位于(过去分词/形容词)。句子缺少谓语,location是名词,located是过去分词,均不能单独作谓语。“be located in”是固定搭配,意为“位于”,主语The Sun Island是第三人称单数,故用is located。
26.A
句意:——我长大后想成为一名科学家。我计划研究保护环境的新方法。——太棒了!每一个小发现都能对我们的世界产生重大影响。
research研究;imagine想象;report报告。根据“I want to be a scientist”及答语中“Every small discovery”可知,科学家的工作是通过“研究”来寻找新方法,符合语境。故选A。
27.B
句意:受到父母的压力,并意识到自己浪费了太多时间,这个男孩下定决心停止玩电子游戏。
controlled控制;determined决心的;managed管理。根据“realizing that he has wasted too much time”可知,男孩意识到错误后应该是“下定决心”改正,固定搭配be determined to do sth. 意为“下定决心做某事”,controlled和managed语义不通,应填determined。
28.B
句意:这个自然奇观可能是由风雨形成的,但我不确定。
must一定;may可能;should应该。根据“but I’m not sure”可知,说话者不确定,表示可能性推测应用may。
29.B
句意:在湖面下方游泳的鱼很小但很可爱。
under在……正下方,指被某物体覆盖或在垂直下方;below在……下方;on在……上面。根据“the surface of the lake”以及选项可知,此处指“湖面以下”,表示处于某水平线以下时常用介词below。
30.B
句意:——你曾经见过一个吸引许多游客的自然奇观吗?——是的,我见过。它非常美丽。
分析句子结构可知,that引导定语从句修饰先行词“a natural wonder”,先行词为单数名词,且描述客观事实,从句谓语动词应用第三人称单数形式,故填attracts。
31.
If we are not careful
we can hurt ourselves easily
根据所给单词和标点符号可知,本句为含if引导的条件状语从句的复合句。“If”引导条件状语从句,放在句首首字母需大写;“we”是从句的主语;“are”是从句的系动词;“not careful”意为“不小心”,作从句的表语;“we”是主句的主语;“can”是主句的情态动词;“hurt”是主句的谓语动词;“ourselves”意为“我们自己”,是反身代词,作hurt的宾语;“easily”意为“容易地”,是副词,修饰动词hurt。故填If we are not careful, we can hurt ourselves easily. “如果我们不小心,我们很容易伤到自己”。
32.I study hard so that I can pass the English exam.
分析所给词及标点,本句是so that引导的目的状语从句,I study hard为主句;so that I can pass the English exam为从句,其中I作主语,can pass作谓语,the English exam作宾语。
33.Try to look on the bright side.
try to do sth.:尽力 / 试着做某事; look on the bright side是固定短语,意为“往好处想、乐观看待事情”。根据所给词以及语意可知,句子是祈使句,动词原形开头。其结构为:结构:Try to + 动词原形look + 介词短语on the bright side。故填Try to look on the bright side。(尽量往好处想乐观的看待事情。)
34.If you take good care of yourself, you’ll get better soon.
分析所给词及标点,本句是含条件状语从句的复合句,you作条件状语从句的主语,take good care of是固定短语作从句谓语,yourself作介词of的宾语;you’ll get better soon是主句,其中you’ll(you will)作主语+助动词,get better作谓语,soon作时间状语。
35.We should learn to relax ourselves.
根据标点和单词提示可知,句子为陈述句且含有情态动词“should”;“learn to do sth.”意为“学会做某事”,其中“to relax ourselves”为不定式短语作宾语,“ourselves”为反身代词作“relax”的宾语。
36.Be more careful next time
根据所给标点可知应用祈使句的形式。分析所给单词,be是动词原形,在祈使句中作谓语,意为“是;成为”;more careful是形容词的比较级形式,作表语,意为“更小心的”;next time是时间状语,意为“下次”。将这些单词按照祈使句的结构组合起来,即“Be+形容词比较级+时间状语”,就得到了句子“Be more careful next time”,意思是“下次要更小心”。
37.It is the biggest desert in the world.
根据所给单词可知,本句可组合为“It is the biggest desert in the world.”,其中“It”意为“它”,作主语,位于句首,首字母大写;“is”意为“是”,作系动词;“the biggest desert”意为“最大的沙漠”,作表语;“in the world”意为“在世界上”,作地点状语。
38.What should we do to help protect it?
分析所给词及标点,本句是特殊疑问句,询问“我们应该做些什么来保护它”。疑问词What位于句首且大写,后接一般疑问句语序,情态动词should后接主语we,实义动词do作谓语核心,to help protect it是目的状语,表示“来保护它”。
39.The Nile is very important in Egypt’s history.
根据所给单词可知,句子为陈述句肯定句。The Nile is very important in Egypt’s history.“尼罗河在埃及历史上非常重要。”其中句子中含有专有名词“The Nile”,可在句子中充当主语;“important”为形容词,可与“is”连接,形成系表结构;“very”为副词,可放在“important”前,故为“is very important”;句子中含有介词和名词所有格,需组合成“in Egypt’s history”,在句子中作时间状语。
40.There are many endangered animals in the rainforest
根据所给词可知,该句为陈述句。结构为:There be + 主语 + 地点状语。There are(有)是存在句的谓语部分,animals(动物)作主语,many(许多)作定语修饰animals,endangered(濒危的)作定语也修饰animals,in the rainforest(在雨林里)作地点状语。故填There are many endangered animals in the rainforest.“雨林里有许多濒危动物。”
41.It is important to protect nature.
句型“It is+形容词+to do sth.”意为“做某事是……的”,It作形式主语接系动词is,形容词important作表语,真正主语是不定式短语to protect nature“保护自然”。
42.The Amazon River is the second longest river in the world.
The Amazon River“亚马逊河”作主语,位于句首,后接系动词is,“the+序数词+最高级”结构the second longest river“第二长的河”作表语,in the world“世界上”作后置定语。
43. didn’t use to
句意:我过去害怕在公共场合讲话。改写时,原句为一般过去时的陈述句,需在主语后添加助动词的否定形式didn’t,并将原句中的used还原为动词原形use,保留to,其余部分保持不变。
44. brave enough
句意:他非常勇敢。他可以独自面对困难。 可合并为 “足够勇敢去做某事”,be + 形容词 + enough to do sth. 意为 “足够……能够做某事”,此处形容词为brave,故填brave enough。
45. Why does feel
句意:她感到很沮丧,因为她没有朋友可以交谈。划线部分“because she has no friends to talk with”表示原因,对原因提问需用疑问词Why;原句谓语动词feels是实义动词,时态为一般现在时,主语she是第三人称单数。变疑问句时需借助助动词does放在主语前;谓语动词feels需恢复原形feel。故填Why;does;feel。
46. Should learn
句意:我们应该学会控制自己的情绪。本题考查含有情态动词的陈述句变为一般疑问句。原句中的情态动词是should,变一般疑问句时,直接将情态动词should提至句首,首字母大写,后接主语we,情态动词 should后面必须接动词原形,即learn。因此第一空填Should,第二空填learn。
47. It’s to
句意:成长并不总是容易的。“It’s + adj. + to do sth.”是固定句型,表示“做某事是……的”,与原句同义。
48. higher than
句意:珠穆朗玛峰是世界上最高的山峰。原句用最高级“the highest mountain”来表达最高的山峰,同义句可转换为“比较级+ than any other +单数名词”结构,表示“比任何其他……都……”,从而表达最高级含义,high的比较级为higher。故填higher;than。
49. How long
句意:这条河长500公里。划线部分为“500 kilometres long”,在英语中,对长度提问,固定使用特殊疑问词组how long。注意句首单词首字母需大写。
50. the most beautiful
句意:这瀑布是所有瀑布中最美的。原句中的形容词是beautiful,这是一个多音节形容词。多音节形容词变最高级时,需在词前加the most。故填the;most;beautiful。
51. don’t think is
句意:我认为这个自然公园不美妙。原句为一般现在时的肯定句,改为否定句时,因主句谓语为think“认为”,英语习惯上否定主句的think而非从句,在think前加don’t,保留从句中的is不变。故①填don’t;②填think;③填is。
52. such that
句意:景色如此迷人,以至于所有游客都喜欢它。so/such…that…表示“如此……以至于……”,其中an amazing view是名词短语,应用such…that…结构。
