Earth Day was funded in 1970 as a day f educatin abut envirnmental issues, and Earth Day 2020 ccurs n Wednesday, April 22—the hliday's 50th anniversary. The hliday is nw a glbal celebratin that's smetimes extended int Earth Week, a full seven days f events fcused n green living.
By the early 1960s, Americans were becming aware f the effects f pllutin n the envirnment. Rachel Carsn's 1962 bestseller Silent Spring pinted ut the dangerus effects f pesticides(杀虫剂) n the American cuntryside. Later in the decade, a 1969 fire n Cleveland's Cuyahga River shed light n the prblem f chemical waste dispsal. Until that time, prtecting the planet's natural resurces was nt part f the natinal plitical plan. Only a small prtin f the American ppulatin was familiar with envirnmental issues—let alne practiced recycling.
Elected t the U.S. Senate in 1962, Senatr(参议员) Gaylrd Nelsn was determined t cnvince the federal gvernment that the planet was at risk. In the fall f 1969, Nelsn, cnsidered ne f the leaders f the mdern envirnmental mvements, annunced the Earth Day cncept at a cnference in Seattle and invited the entire natin t get invlved. He later recalled: "The respnse was electric(高度刺激的). Telegrams, letters and telephne inquiries pured in frm all acrss the cuntry. The American peple finally had an pprtunity t express their cncern abut what was happening t the land, rivers, lakes and air."
Public pinin plls(民意调查) indicated that in May 1971, 25 percent f the U.S public declared prtecting the envirnment t be an imprtant gal, a 2,500 percent increase ver 1969.
Earth Day kicked ff the envirnmental decade with a bang, as Senatr Nelsn later put it. During the 1970s, a number f imprtant envirnmental laws were passed, such as the Clean Air Act, the Water Quality Imprvement Act and the Endangered Species Act. Anther key develpment was the establishment f the Envirnmental Prtectin Agency(EPA) in December 1970, which was tasked with prtecting human health and safeguarding the natural envirnment—air, water and land.
8.What d we learn abut the circumstances in America befre Earth Day was funded?
A.The veruse f pesticides had little impact n the American cuntryside.
B.The fire n Cuyahga River was caused by imprper chemical waste dispsal.
C.The gvernment highly valued the prtectin f the natural resurces.
D.Only a few Americans were familiar with envirnmental issues and practiced recycling.
9.What can be inferred frm the third paragraph?
A.Nelsn cnvinced the federal gvernment that the planet was at risk.
B.Nelsn rganized the mdem envirnmental mvements all by himself.
C.The Earth Day successfully arused the public's interest in envirnmental issues.
D.The electric pwer supply had been cut ff because numerus telephne inquiries pured in.
10.Why was the Envirnmental Prtectin Agency set up?
A.T cllect public pinins.B.T kick ff the envirnmental decade.
C.T change public attitudes.D.T prtect human beings and nature.
11.What d yu think the authr will discuss later?
A.Earth Day celebratins have grwn and spread arund the glbe.
B.EPA prtects human health and ur natural envirnment.
C.The envirnmental laws cme int effect.
D.Senatr Nelsn's achievements are remarkable.

Tday we knw Antarctica as an extreme envirnment cntaining ice and snw. But new research prvides evidence that the area had a rainfrest in the past.
The researchers cllected a piece f Earth sediment(沉淀物) frm under the seaflr ff the cast f Antarctica. In the sediment, they discvered frest material that was estimated t be abut 90 millin years ld. This wuld have been in the Cretaceus Perid, when dinsaurs were the main land animals. The sediment was remved by scientists n the research icebreaker RV Plarstern in the Amundsen Sea near Pine Island Glacier.
Jhann Klages is a gelgist with the Alfred Wegener Institute, Helmhltz Center fr Plar and Marine Research in Germany. He was the lead writer f a study n the findings, published in the jurnal Nature. He said the sediment was cllected frm a depth f abut 30 meters belw the cean flr. Klages said an examinatin shwed that the material didn't frm in the cean.
The researchers estimate that the area—abut 900 kilmeters frm the Suth Ple—had average yearly temperatures f abut 12 t 13 degrees Celsius. During the warmest summer mnths, average temperatures likely reached between 20 and 25 degrees Celsius. The sil included fine dirt particles(颗粒) and hard clay, as well as substances linked t at least 65 different kinds f plants, the study fund. Klages added that the plants included trees, ferns and flwering plants. While n animal remains were fund, Klages said there were likely dinsaurs, flying reptiles(爬行动物) and many insects in the envirnment.
The research represents new evidence f the majr climate changes Earth has experienced in the past — and is currently underging tday. The sil in the sediment dates back t the planet's warmest perid f the past 140 millin years, with sea level abut 170 meters higher than tday. The researchers said that the rainfrest envirnment in Antarctica was especially surprising because each year, the area experiences a fur-mnth plar night when there is n sunlight t fuel plant life. Klages said n ice sheets were present during the time, but seasnal snwfall was likely.
12. Hw did the researchers cme t their findings?
A. By cllecting data n climate.
B. By researching special plants.
C. By explring ice in Antarctica.
D. By analyzing the Earth sediment.
13. What did the researchers say abut the sediment?
A. Its material develped in the cean.
B. Its material frmed n the land.
C. It dates back t cld times in Antarctica.
D. It cntained different animal remains.
14. What des the authr indicate in the last paragraph?
A. There were ice sheets 140 millin years ag.
B. Seasnal snwfall made the frest disappear.
C. Antarctica's natural envirnment has changed greatly.
D. Plar nights in Antarctica are getting shrter than befre.
15. What is the main idea f the text?
A. Antarctica is getting warmer like befre.
B. Varius wildlife nce existed in Antarctica.
C. Antarctica had a different histry f climate.

第二节
答案：36 times ; 37 lwer; 38 with; 39 a; 40 analyzing ; 41 seen; 42 dramatic ;43 respnded ; 44 sftly; 45 which
解析：36考查名词单复数。句意为:研究发现,之前白冠麻雀城市繁殖地区的噪声等级是乡下繁殖地区的三倍。time在句中表倍数,为可数名词。空前有数词there ,故设空处填复数形式times。
37考查形容词的比较等级。句意为:但是在疫情期间,研究人员注意到,城区的噪声等级大大降低。根据句意可知,此处是和正常状态下相比。故用比较级lwer。
38考查介词。句意为:事实上,疾病大流行期间城市的噪声等级和20世纪50年代中期的交通噪声等级持平。be cnsistent with意为"和……保持一致",故填with。
39考查冠词。句意为:研究人员指出:"换句话说,新冠肺炎疫情封锁给旧金山湾带来了一个安静的春天"。这里泛指一个春天,应用不定冠词,且silent的发音以辅音音素开头,故用冠词a。
40考查非谓语动词。句意为:通过分析金门大桥的车流量数据……介词后的动词应用-ing形式,故填analyzing。
41考查非谓语动词。句意为: ……2020年四月至五月的车流量回落到了1954年以来的最低水平。分析句子结构可知, nt _______ since 1954在句中作后置定语,修饰levels ,levels和动词see之间为逻辑上的被动关系,故填seen。
42考查词性转换。句意为这表明人类行为的短时间剧变有效地消除了持续半个多世纪的城区噪声污染。change在此处为名词,应用形容词修饰,故填dramatic。
43考查动词的时态。句意为:鸟类对此的反应是用更低的振幅(音量)唱出更优美的歌声,最大限度地增加交流距离和显著性。分析句子成分可知,设空处在句中作谓语,此处是对过去事实的描述,应用一般过去时,故用动词的过去式respnded。
44考查词性转换。句意为:研究人员在研究中讲道:"我们发现,当噪声水平降低时,鸟儿的叫声史柔和。" sang为动词,应用副词修饰,故填sftly。
45考查定语从句。句意为:研究人员说,"此外,信号噪声比的加倍有助于解释媒体关于鸟叫声在封锁期间听起来更嘹亮的报道"。分析句子结构可知,此处为非限制性定语从句,先行词为前面整句话,设空处在从句中作主语,故填which。
