Ⅳ.阅读理解
Early in the autumn f 1674,Henry Oldenburg,secretary f the Ryal Sciety in Lndn,received an extrardinary letter.Sent by Antni van Leeuwenhek,a draper (布料商) frm Delft in the Netherlands,it cntained an unlikely-sunding claim.
Using a micrscpe f his wn inventin,van Leeuwenhek had seen tiny creatures,invisible t the naked eye,living in lake water.Sme f these “animalcules (微生物)” were s small,and he later estimated that 30 millin f them wuld still be smaller than a grain f sand.
Ryal Sciety fellws culdn’t believe it.Even with his mst pwerful instruments,the celebrated English micrscpist Rbert Hke had never bserved anything like the little creatures.
In fact,the Dutchman had develped far superir lenses t Hke’s,and had discvered bacteria and prtzans (原生动物).By prducing even smaller and mre curved lenses—using a technique that he kept secret—van Leeuwenhek was able t magnify bjects up t 500 times.As well as discvering micr-rganisms,he was the first t see red bld cells.
In 1677,van Leeuwenhek sent the Sciety further animalcule bservatins.Hke eventually imprved his wn micrscpes t the pint where he,t,culd see the tiny creatures.Three years later van Leeuwenhek was made a fellw.
It was nt until 1890,mre than 160 years after van Leeuwenhek’s death,that bacteria were linked with diseases.“Reading van Leeuwenhek’s letters,yu very much get the impressin f smebdy dazzled (眩晕的) by what he was finding,” says Lesley Rbertsn,leader f the archives at Delft University’s schl f micrbilgy.“He thught he’d fund a whle new wrld—but he certainly never picked up n the cnnectin with illness.”
【语篇解读】本文是一篇说明文。文章讲述了布料商出身的van Leeuwenhek发明了显微镜。他的发明使得发现更小、更清晰的事物成为可能,这为把细菌与疾病联系起来奠定了基础。
1.What did Antni van Leeuwenhek see with his wn micrscpe?
A.A letter.
B.Bacteria and prtzans.
C.Small animals in the water.
D.The element f water.
【答案】B
【解析】细节理解题。根据第四段内容可知,荷兰人已经通过改良的镜片发现了细菌和原生动物,Antni van Leeuwenhek通过自己的显微镜看到的tiny creatures就是细菌和原生动物。
2.Frm the passage we can cnclude that .
A.van Leeuwenhek knew the tiny creatures in the water had smething t d with illness
B.van Leeuwenhek was the first t discver bacteria
C.van Leeuwenhek was the first t use the micrscpe
D.van Leeuwenhek was the first t knw hw t bserve bacteria and prtzans
【答案】C
【解析】推理判断题。通读全文可知,尽管荷兰人也看到细菌和原生动物,但是他们使用的是改进后的镜片,而不是显微镜,因此选择C项。
3.What des the underlined wrd “magnify” in the furth paragraph mean?
A.T clear away.
B.T imprve.
C.T cllect.
D.T make smething appear larger.
【答案】D
【解析】词义猜测题。根据句意以及后文的“up t 500 times”可知,他的显微镜能把物体放大500倍,因此得出答案为D项。
Ⅴ.应用文写作
