五、短文填空
阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。
Only about 2.5 per cent of the earth’s water is freshwater. Of that, nearly 70 per cent is frozen in huge and 65 (peace) glaciers and ice caps (冰川和冰冠). About 30 per cent is groundwater, which is important for human 66 (develop) and daily life. It hides under mountains, plains and even deserts, and is called aquifers (含水层).
Groundwater is 67 important part of earth’s water cycle. Some groundwater naturally rises and 68 (pour) out onto earth’s surface through springs (泉). In fact, we use 200 times more groundwater than oil.
As human-caused climate change dries out parts of the planet, the need for groundwater will rise, 69 the same time, climate change may make storms much 70 (strong). Heavier rains are more likely to rush 71 (direct) into lakes and rivers than flow into soil. So there may be less groundwater.
Meanwhile, human activities have 72 (pollute) groundwater in many places. Chemicals from farming or mining (采矿) flow into these aquifers.
What can be 73 (do)? Reduce pollution and find ways to purify (净化) groundwater. 74 we act now, we will hardly get clean water in the future.
参考答案
一、
1.more strongly
【解析】句意:风比之前刮得更猛烈了,所以我们应该关上所有的窗户。“than before”为比较级的标志词,提示此处应用副词的比较级形式修饰动词。strong是形容词,其副词形式是strongly,strongly是多音节副词,其比较级是在前面加more,故填more strongly。
2.noisy

25.earthquake
【解析】句意:2023年这场可怕的地震之后,许多人无家可归。括号内汉语提示为地震,terrible是形容词,后面修饰名词,the表示特指这一场地震,因此使用名词单数earthquake。
26.systems
【解析】句意:许多现代家庭使用智能系统来控制灯光和温度,从而节省能源和金钱。“系统”对应的英文单词是system,为可数名词。根据句意,此处指多个家庭使用多个系统,且空前无冠词a/an,故应用复数形式systems。
27.topic’s
【解析】句意:该话题的目标是在下个月之前为乡村图书馆收集500本旧书。括号中给出中文“话题”,对应英文单词为“topic”。句中“goal”为名词,前面需要用所有格形式表示“话题的(目标)”,因此使用topic的所有格形式“topic’s”。

33.led
【解析】句意:太多的工作和太少的休息导致了疾病,所以他看起来不健康。根据对句子结构的分析可知,前面一个并列分句没有谓语动词,所以此处需填入表“导致”的动词。又根据“so he looked unhealthy.”可知,前面并列分句的时态也为一般过去时。lead“导致”,为动词,其过去式为led。故填led。
34.flood
【解析】句意:洪水来临的时候,人们迅速转移到了地势更高的地方。本句为时间状语从句,空格前有定冠词the,后面可接单数名词特指这场洪水;flood作名词意为“洪水”,符合语境。
三
35.B
【解析】句意:我们明天要谈论关于“我最喜爱的食物”这个话题。
考查介词辨析和名词辨析。to到;about关于;word单词;topic话题。第一空,“talk about”意为“谈论某事”,后接谈论的内容,“talk to”意为“和某人说话”,后接人,所以排除A项和D项;第二空,“My favourite food”是要谈论的话题,而非单词,排除C项。故选B。
36.A
【解析】句意:将来,更多的东西会连接到互联网,所以生活将继续改变。
考查连词及句子逻辑关系。so life will continue to change因此生活将继续发生变化,so表因果,引出结果;although this will really be possible尽管这确实是可能的,although表让步,引导让步状语从句; but doctors can provide better treatment但是医生能提供更好的治疗,but表转折;because this could lead to serious problems因为这可能会导致严重的问题,because表因果,引出原因。根据句子逻辑,“更多东西连接互联网”是原因,后续应接由此产生的结果。so用于引出因果关系中的结果,符合“联网范围扩大→生活继续变化”的逻辑链条。故选A。
37.A
【解析】句意:鲍勃很高,但他不能打篮球。考查连词辨析。although尽管,表让步;but但是,表转折;此二者不可混用。because因为,表原因(前果后因);so所以,表结果(前因后果);此二者也不可混用。本句前后是转折关系,需用but连接;根据句意结构和语境,可知选A。
38.A
【解析】句意:这场大暴风雨切断了电力供应,所以我们晚上不得不使用蜡烛。
cut off切断;took off起飞;put off推迟;turned off关掉。根据“so we had to use candles at night”可知停电了,暴风雨导致供电中断应用cut off。turned off通常指人为关闭,不符合语境。
39.B
【解析】句意:听!雷声太大了,以至于我听不见你在说什么。
wind风;thunder雷声;snow雪;rain雨。根据“so loud that I can’t hear what you are saying”可知,此处强调声音巨大影响听力,snow是无声的,wind和rain虽有声音,但thunder是最符合“音量极大、会干扰人正常对话”的自然声响,故填thunder。
40.A
【解析】句意:大雨过后河水上涨了,许多田地都被水淹没了。
rose (rise 的过去式) 上升,上涨;raised (raise 的过去式) 举起,提高;grew (grow 的过去式) 生长,变得;fell (fall 的过去式) 落下,下降。根据“after the heavy rain”和“many fields were under water”可知,大雨导致河水水位上升,且主语The river后无宾语,需用不及物动词,rose符合语境。
41.A
【解析】句意:湿地里所有的生物都需要水来维持生命。
living活着的;alive活着的;lively生动的,活泼的。第一空修饰名词things,作定语,指“活着的”,应用living;第二空在keep后作表语,指保持“活着的”状态,应用alive。应填living;alive。
42.B
【解析】句意:他们没有把火扑灭就离开了公园里野餐的地方,所以它导致了上周末的一场大火。幸运的是,没人受伤。
happened to碰巧;led to导致;connect with与……联系;depended on依赖。根据“They left the picnic place in the park without putting out the fire”可知,没灭火离开会引发后果。结合语境及last weekend可知需用过去式,且表示因果关系,led to符合题意。
43.D
【解析】句意:他感到有点累,然后很快就睡着了。
a bit和a little可修饰形容词,a bit of后接名词;fall asleep意为“入睡”,sleepy意为“困倦的”。根据第一空后为形容词tired,排除B;根据第二空固定搭配fall asleep,排除A和C,应选D。
44.C
【解析】句意:我们想和你一起去购物,但是我们作业太忙了。
or或者;and和;but但是;so所以。根据“We’d like to go shopping with you...we are too busy with homework.”可知,前句提到想要去购物,后句说太忙了,前后句意存在转折关系,用but连接。
45.B
【解析】句意:你能大声一点说话吗?我听不清你说的话。
slowly缓慢地;clearly清晰地;quietly安静地;closely密切地。前文请求对方大声说话,说明听不清晰,应填clearly。
46.D
【解析】句意:我们听到一只小猫在灌木丛里哭。
分析句子成分可知,We作主语(S),heard作谓语(V),a little cat作宾语(O),crying作宾语补足语(OC),补充说明宾语的动作状态,符合S + V + O + OC结构。
47.A
【解析】句意:我们应该种植更多树木来保护土壤不被雨水冲走。
protect; from构成固定搭配protect...from...“保护……免受……”;keep; off意思是“使……不靠近”;prevent正确搭配为prevent...from...;stop正确搭配为stop...from...。结合句子语境,此处选用protect; from。
48.A
【解析】句意:当地震开始时,老师告诉学生们要冷静下来并躲在桌子下面。
calm down冷静下来;put down放下;sit down坐下;fall down摔倒。根据“When the earthquake started”及“hide under the desks”可知,遇到地震紧急情况时,首先要保持镇定,才能安全躲避,所以这里应填calm down。
49.C
【解析】句意:——我们今天必须完成关于自然保护区的报告吗?——不,你不必。你可以明天交。
mustn’t禁止;can’t不能;needn’t不必;shouldn’t不应该。对“Must”开头的疑问句作否定回答,应用“needn’t”,表示“不必”。故选C。
四、
50. is getting warmer friendly
【解析】根据句意可知,第一空到第三空表示“正在变暖”,“变得”用“get”,结合语境可知,句子时态是现在进行时,其结构为“be+动词的现在分词”,主语“The ocean”是第三人称单数,be动词用“is”,“get”的现在分词是“getting”,“更暖和的”用“warmer”;第四空表示“适宜的”,用形容词“friendly”作定语修饰名词“environment”。故填is;getting;warmer;friendly。
51. makes very comfortable
【解析】根据中英文对照可知,此处缺少“让”和“很舒服”。make“让,使”,句子描述的是一般事实,时态为一般现在时,主语是The warm sunshine,所以谓语用动词三单形式makes;very“很”,是副词;comfortable“舒服的”,是形容词。故填makes;very;comfortable。
52. told us an interesting story
【解析】tell sb an interesting story“给某人讲一个有趣的故事”。时态为一般过去时,陈述过去发生的事,谓语动词用过去式told;us“我们”,宾格,作宾语。故填told;us;an;interesting;story。
53. to use eco-friendly products
【解析】原句中“使用环保产品”是关键词。encourage sb. to do sth.是固定搭配,意为“鼓励某人做某事”,故第①空填不定式符号to,第②空填动词原形use表示“使用”。“环保”用形容词eco-friendly表示,修饰名词“产品”,故第③空填eco-friendly。“产品”用product,本句的“环保产品”是泛指市面上所有环保类商品,不是单独一件,故第④空填products复数。
54. set up
【解析】原句中“建立”是关键词,“建立”在英语中对应固定动词短语set up;时间状语Last year表明句子时态为一般过去时,动词set的过去式为不规则变化,仍为set,故填set up。
55. keep forests safe
【解析】根据中英文对照可知,此处缺少“保持森林安全”,应用“keep+宾语+形容词”结构;森林:forest,可数名词,此处应用复数表泛指;安全的:safe。help (to) do sth.“帮助做某事”,keep用原形。故填keep;forests;safe。
56. lead to
【解析】对照中英文,lead to“导致”符合题意,为动词短语,will接动词原形。故填lead;to。
57. provides us with offers us space
【解析】根据中英文对照可知,此处缺少“为我们提供”以及“为我们提供空间”。“为我们提供”可译为“provides us with”,主语“It”是第三人称单数,时态是一般现在时,谓语动词用第三人称单数形式;“为我们提供空间”对应“offers us space”,and并列结构此处用动词三单形式。故填provides;us;with;offers;us;space。
58. in order to
【解析】根据句意可知,此处表示“以便,为了”,用短语“in order to” ,该短语在句中连接前后两个句子成分,表示目的。故填in;order;to 。
59. in the daytime
【解析】根据句意可知,此处表示“在白天”,用介词短语“in the daytime”,且此短语在句中作时间状语。故填in;the;daytime。
60. all year round
【解析】根据中英文对照可知,此处缺少“一整年”。“一整年”译为“all year round”。故填all;year;round。
61. how to
【解析】how to do sth“如何做某事”。故填how;to。
62. quite a few
【解析】根据中英文对照可知,空格处为“相当多”quite a few。故填quite;a;few。
63. are facing
【解析】结合中英文,此处时态为现在进行时,表示每天都正在面对问题,主语是you,需用现在进行时结构are+动词现在分词形式,face“面对”。故填are;facing。
64. went on and on
【解析】根据中英文对照可知,空处缺“下了没完没了”的英文。“go on and on” 是固定搭配,表示“持续不停、没完没了”,根据“had”可知,本句时态为一般过去时,谓语动词需用过去式。故填went;on;and;on。
五、
65.peaceful 66.development 67.an 68.pours 69.at 70.stronger 71.directly 72.polluted 73.done 74.Unless
【解析】本文是一篇说明文。主要介绍了地下水资源的重要性,指出其正受气候变化与人类活动的威胁,呼吁尽早行动保护地下水。
65.句意:其中近70%冻结在广袤静谧的冰川和冰冠之中。and连接两个并列的成分,huge为形容词,意为“巨大的”,peace为名词,形容词形式为peaceful。
66.句意:约30%的淡水是地下水,它对人类发展和日常生活至关重要。for是介词,介词后需要接名词性成分作宾语。develop“发展”,动词,名词形式为development。
67.句意:地下水是地球水循环的一个重要组成部分。“important”以元音音素/ɪ/开头,此处表示“一个重要组成部分”,用不定冠词an。
68.句意:部分地下水会自然抬升,经由泉涌流到地球表面。and连接并列谓语,和rises一致,用一般现在时的第三人称单数形式,pour第三人称单数形式为pours。
69.句意:人类活动引发的气候变化导致地球部分地区不断干旱,人类对地下水的需求会随之上升;与此同时,气候变化也会让风暴变得更强。空格前提出“人为导致的气候变化让地球部分区域变得干旱人类对地下水的需求会上升”,空格后要讲气候变化带来的另一个同步发生的负面影响,at the same time意为“与此同时”,固定搭配,承接了上文“需求上升”的变化,又引出了下文同时发生的负面情况。
70.句意:人类活动引发的气候变化导致地球部分地区不断干旱,人类对地下水的需求会随之上升;与此同时,气候变化也会让风暴变得更强。much后接形容词比较级,此处指“气候变化会让风暴更强”,strong的比较级stronger。
71.句意:强降雨更可能直接地涌入河湖,而非渗入土壤。此处需要副词修饰动词rush,direct“直接的”,形容词,副词形式directly表示“直接地”,符合语义。
72.句意:与此同时,人类活动已经在很多区域污染了地下水。由助动词“have”可知,句子的时态为现在完成时,其结构为:have/has+过去分词,表示过去发生的动作,对现在造成的结果,本文这里说人类活动污染地下水,是从过去到现在已经发生的情况,对现在的结果就是“如今很多区域地下水已经被污染”,pollute“污染”,动词,过去分词为polluted。
73.句意:我们能做些什么呢?主语What和动词do之间是被动关系,本句是情态动词的被动语态,其结构为:情态动词+be+ 过去分词,do的过去分词done。
74.句意:除非我们现在就行动,否则未来我们几乎不可能获得干净的水资源。根据“…we act now, we will hardly get clean water in the future.”可知,后半句“未来我们几乎不会获得干净的水”是结果,前半句“我们现在就行动”是条件,因此用unless引导条件状语从句,句子首字母大写。

Only about 2.5 per cent of the earth’s water is freshwater. Of that, nearly 70 per cent is frozen in huge and 65 (peace) glaciers and ice caps (冰川和冰冠). About 30 per cent is groundwater, which is important for human 66 (develop) and daily life. It hides under mountains, plains and even deserts, and is called aquifers (含水层).
Groundwater is 67 important part of earth’s water cycle. Some groundwater naturally rises and 68 (pour) out onto earth’s surface through springs (泉). In fact, we use 200 times more groundwater than oil.
As human-caused climate change dries out parts of the planet, the need for groundwater will rise, 69 the same time, climate change may make storms much 70 (strong). Heavier rains are more likely to rush 71 (direct) into lakes and rivers than flow into soil. So there may be less groundwater.
Meanwhile, human activities have 72 (pollute) groundwater in many places. Chemicals from farming or mining (采矿) flow into these aquifers.
What can be 73 (do)? Reduce pollution and find ways to purify (净化) groundwater. 74 we act now, we will hardly get clean water in the future.
