Ⅰ.阅读理解
(2021 河北石家庄二中月考)
The history of microbiology begins with a Dutch cloth maker named Antoni van Leeuwenhoek, a man of no formal scientific education. In the late 1600s, Leeuwenhoek, inspired by the magnifying lenses( 放大的镜
片 ) he used to examine cloth, built some of the first microscopes. He developed a technique to improve the quality of tiny, rounded lenses, some of which could magnify an object up to 270 times. After removing some plaque(牙斑) from between his teeth and examining it under a lens, Leeuwenhoek found tiny twisting creatures, which he called “animalcules” .
His observations, which he reported to the Royal Society of London, are among the first descriptions of microbes. Leeuwenhoek discovered an entire universe invisible to the human eye. He found different microbes in samples of pond water, rain water, and human blood. He gave the first description of red blood cells, observed plant tissue, examined muscle, and investigated the life cycle of insects.
Nearly two hundred years later, Leeuwenhoek’s discovery of microbes helped French chemist and biologist Louis Pasteur to develop his “theory of disease”. This concept suggested that disease originates from germs attacking and weakening the body. Pasteur’s theory later helped doctors to fight infectious diseases including anthrax, diphtheria,
polio, smallpox, tetanus, and typhoid. All these breakthroughs were the result of Leeuwenhoek’s original work. Leeuwenhoek did not foresee this legacy.
In a 1716 letter, Leeuwenhoek described his contribution to science this way:“My work, which I’ve done for a long time, was not pursued in order to gain the praise I now enjoy. It was chiefly from a strong desire for knowledge, which I notice resides in me more than in most other men. And therefore, whenever I found out anything remarkable, I have thought it my duty to put down my discovery on paper, so that the scientific community might be informed thereof.”
1.Which of the following best describes Leeuwenhoek
A.A trained researcher with an interest in microbiology.
B.A curious amateur(业余爱好者) who made pioneer studies of microbes.
C.A talented scientist interested in finding a cure for disease.
D.A bored cloth maker who accidentally made a major discovery.
2.What does the underlined phrase “this legacy” in Paragraph 3 refer to A.The discovery of microbes.
B.Pasteur’s theory of disease.
C.Leeuwenhoek’s contribution.
D.The origin of the tiny organism.
3.What does the quote from Leeuwenhoek’s letter suggest
A.He admitted that many of his discoveries happened by chance.
B.He considered his work to be central to later medical breakthroughs.
C.He was greatly concerned with improving people’s living conditions. D.He believed the sharing of knowledge was a key to scientific progress.
4.What is the correct order of the following events
a.Magnifying lenses were built.
b.The “theory of disease” was put forward.
c.Microbes were discovered in samples of waters.
d.Leeuwenhoek’s first microscopes were successfully developed. e.Leeuwenhoek explained his thoughts upon his own contribution.
A.a-d-c-e-b. B.d-a-c-e-b.
C.a-d-c-b-e. D.d-a-e-b-c.

解”。
2.finding 考查名词。由设空处前的 a German scientist(主语)和 made(谓语)可知设空处作宾
语, 由前面的不定冠词 a 可知应填名词 finding,意为“发现”。
3.Initially 考查副词。设空处置于句首,在句中作状语,修饰整个句子,应用副词 Initially,意为
“最初”。
4.by 考查介词。此处指某些城市的房价在过去几年里下降了 10%,表示“ 下降了 ……”,用
decrease by... 。故填 by。
5.for 考查介词。blame sb. for sth.意为“把某事归咎于某人”。故填介词 for。此处指你不应
该把你的失败归咎于其他人。
Ⅱ.1.同意 2.定期订购 3.名词;牢房 4.形容词;可靠的 形容词;确实的,具体的 名词;嫌疑

Ⅲ.1.what my father has taught me 是表语从句,设空处在从句中作 taught 的直接宾语, 且此处表示“父亲教我的道理”,故填 what。
2.when 句意:对这个足球明星来说,最好的时刻是他踢进决胜球的时刻。 he scored the
winning goal 是表语从句,结合句意可知设空处在从句中作时间状语,故填 when。

3.you should study hard
Ⅰ.本文是一篇记叙文。文章主要讲述了安东尼 ·列文虎克制作显微镜的过程以及他对微生物学
做出的贡献和他本人对自己的贡献的看法。
1.B 细 节 理 解 题 。 根 据 第 一 段 中 的 “a Dutch cloth maker”“a man of no formal scientific education”和第二段中的“His observations...are among the first descriptions of microbes.”可知,列
文虎克是一个求知欲强的业余爱好者,他对微生物进行了开创性的研究。故选 B。
易错归因
本题容易误选 D 项,需要注意的是 D 项中的 bored 是一个带有感彩的形容词,但在文
章中无从体现。
2.C 词义猜测题。 this legacy 前面说到 Louis Pasteur 的“theory of disease”和这个理论帮助 医生们战胜感染性疾病的突破,所有的这些都源自列文虎克的贡献,但是他并没有预见到这些,
由此推知,画线词指的是“列文虎克的贡献” 。故选 C。
3.D 推理判断题。根据最后一段中的“whenever I found out...be informed thereof”可知,每当列 文虎克发现任何值得注意的事情时,他都认为他有责任把他的发现写在纸上, 以便让科学界知 道。由此可推知, 引用的列文虎克的信中的话表明他相信分享知识是科学进步的关键。故选 D。
4.A 推理判断题。根据文章内容可知,事件的正确顺序是 a-d-c-e-b。
易错归因
本题容易误选 C 项,混淆的关键点在于 b 和 e 谁先出现的,需要注意的是虽然文章是在第 三段讲到“theory of disease”,在第四段说到列文虎克解释了他对自己贡献的想法,但是要注意 这两者发生的时间,“theory of disease”是在近两百年之后提出来的,这远远要比 1716 年列文虎
克解释他对自己贡献的想法靠后。

Ⅲ.本文是一篇新闻报道。Alaina 发明了一个系统,赢得了博通大师赛的冠军。文章对她的获
奖项目以及她获奖后想做的事情做了介绍。
1.were announced 考查动词的时态、语态及主谓一致。“获奖者” 与“ 宣布”之间为被动关系, 应用被动语态;根据句中的时间状语 last month 可知应用一般过去时;主语为 The winners,谓语

6.images 考查名词复数。此处指展示支柱另一侧影像的设备,image 意为“影像”,由语境可知
此处表示复数含义。故填 images。
7.in 考查介词。此处指然后司机就可以看到什么在盲区里。in the blind spot 表示“在盲区
里”,故填 in。
8.surprised 考查形容词。由设空处前的 she(主语)和 was(系动词)可知此处应用形容词作表
语,且主语为人(she 指 Alaina),故用 surprised,表示“(人)感到吃惊的”。
9.invention 考查名词。由设空处前的形容词性物主代词 her 可知此处应填名词 invention 。 10.making 考查现在分词。该句中,said 后面的宾语从句中已有谓语,故此处应用非谓语动词; 此处表示她想改善画面,使它在任何天气或一天中的任何时间都容易看清楚,make 与其逻辑
主语 she 之间为主动关系,此处应用现在分词作状语。故填 making。
【高频词汇】
