展开阅读下列材料,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。
If plastic had been invented when the Pilgrims sailed frm Plymuth, England, t Nrth America—and their Mayflwer had been stcked with bttled water and plasticwrapped snacks, their plastic waste wuld likely still be arund fur centuries later. Atlantic waves and sunlight wuld have wrn all that plastic int tiny bits. And thse bits might still be flating arund the wrld's ceans tday, waiting t be eaten by sme fish r yster, and finally perhaps by ne f us.
Because plastic wasn't invented until the late 19th century, and its prductin nly really tk ff arund 1950, we have a mere 9.2 billin tns f the stuff t deal with. Of that, mre than 6.9 billin tns have becme waste. And f that waste, a surprising 6.3 billin tns never made it t a recycling bin—the figure that shcked the scientists wh published the numbers in 2017.
N ne knws hw much unrecycled plastic waste ends up in the cean, the earth's last sink. In 2015, Jenna Jambeck, a University f Gergia engineering prfessr, caught everyne's attentin with a rugh estimate: between 5.3 millin and 14 millin tns f plastic waste each year just cme frm castal regins.
Meanwhile, cean plastic is estimated t kill millins f marine (海洋的) animals every year. Nearly 700 species, including endangered nes, are knwn t have been affected by it. Sme are harmed visibly, stuck by abandned things made f plastic. Many mre are prbably harmed invisibly. Marine species f all sizes, frm zplanktn t whales, nw eat micrplastics, the bits smaller than nefifth f an inch acrss.
“This isn't a prblem where we dn't knw what the slutin is,” says Ted Siegler, a Vermnt resurce ecnmist wh has spent mre than 25 years wrking with develping natins n garbage. “We knw hw t pick up garbage. Anyne can d it. We knw hw t deal with it. We knw hw t recycle.” It's a matter f building the necessary institutins and systems, he says, ideally befre the cean turns int a thin sup f plastic.
1.Why des the authr mentin the Pilgrims in Paragraph 1?
A.T prve plastic was difficult t invent.
B.T intrduce what marine animals like eating.
C.T tell the Pilgrims cntributed a lt t the marine prtectin.
D.T shw plastic waste has a lasting effect n the cean.
2.What's the main truble marine animals face accrding t the text?
A.Lacking prtectin.
B.Being stuck by plastics.
C.Being caught by humans.
D.Treating plastics as fd.
3.What des Ted Siegler want t tell us in the last paragraph?
A.Sme peple dn't knw the slutin f plastics waste.
B.Plastics will turn the cean int a sup f plastic.
C.It's time t take measures t deal with plastic waste.
D.Peple shuld avid using plastics t prtect the cean.
4.Frm which is the text prbably taken?
A.A bilgy textbk.

课时作业(四) Cmprehensive Test fr Unit 1
Ⅰ.阅读理解
【语篇解读】 本文是一篇说明文。如今塑料垃圾已经严重污染了我们的环境,尤其是海洋环境,人类应该采取措施改变这一现状。
1.答案与解析:D 判断推理题。作者在第一段提到假如最初的移民者向北美大陆进发时就携有塑料的话,那么这些塑料垃圾有可能被遗留到今天,这说明塑料垃圾对海洋有着深远持久的影响。
2.答案与解析:D 细节理解题。根据第四段最后两句话内容可知,很多海洋生物把塑料垃圾当成了食物。
3.答案与解析:C 判断推理题。根据最后一段Ted Siegler提到的内容,虽然我们都知道怎么去应对海洋垃圾问题,但是我们要付出实际行动,例如,我们要建立必要的制度和体系等。
4.答案与解析:C 文章出处题。本篇文章是关于海洋垃圾和海洋生物保护的,最有可能出现在环境报告中,故选C。
Ⅱ.阅读七选五
【语篇解读】 本文是一篇说明文。流感危害极大,最好的办法就是接种疫苗。本文介绍了关于流感疫苗的一些小知识。
1.答案与解析:D 根据下文unless yu are allergic t eggs r any ingredient in the vaccine可知其意为:除非你对鸡蛋或疫苗的成分过敏。其言外之意就是建议人们进行接种防疫。故选D项。
2.答案与解析:A 根据下文The flu vaccines are amng the safest medical prducts in use, and the risk f a flu sht ding yu any harm is extremely small可知,流感疫苗是非常安全的,副作用极小。A选项能够概括本段的主要内容。
3.答案与解析:B 根据前文The nasal spray ptin frm previus years wn't be an ptin fr the 20172018 flu seasns可知,鼻腔喷剂将在20172018年度弃用,这与B选项能够构成因果关系。
4.答案与解析:F 下文中的higher levels f antibdies与F选项中的measured the amunt f flu antibdies信息呼应。
5.答案与解析:G 根据前文Prtecting neself is an altruistic act可知,接种疫苗也是一种利他行为,这与G选项构成同义转述。
Ⅲ.完形填空
【语篇解读】 本文是一篇记叙文。松鼠贝拉被鲁比·哈里森带回家后得到了很好的照顾。鲁比不仅给了贝拉一个家,还和其他三只被收养的松鼠住在一起。几只松鼠最终被放养之后,贝拉几乎每天都会来看望鲁比和她的家人。
1.答案与解析:B 考查动词。根据空后的内容“badly wunded her”可知,前面应该是表示“一只猫头鹰袭击/攻击了她”。结合常识可知此处表示因果关系。apprach靠近;attack攻击;fllw跟随,听懂;advance前进。
2.答案与解析:C 考查名词。stand n chance f意为“没有.的机会”。这里表示“贝拉在野外受了伤,根本不可能活下来。”
3.答案与解析:D 考查副词。不过幸运的是,鲁比把她带回了家。结合下文内容的描述可知,是鲁比救了贝拉,那肯定是“幸运的事情”。
4.答案与解析:A 考查名词。句意:鲁比不仅给了贝拉一个居所,而且还给了她一个由另外三只收养的松鼠组成的家庭。series系列;hspital医院;lcatin位置,均不符合语境内容。
5.答案与解析:B 考查名词。结合上下文的表述可知,这里指的是他们长得很快,不过鲁比并没有驯养它们。她说,“它们是野生动物的一部分,而不是宠物”。结合句意可知wild符合题意。
6.答案与解析:D 考查动词。根据上一句“It was time t say gdbye”可知,这里是在描述鲁比把几只松鼠放归大自然的事。disappear意为“消失”,与上一句话内容相符。
7.答案与解析:A 考查动词。句意:鲁比看到它们消失在树林里,从没想过会经常见到他们。然后,一开始,其他三个回来吃了一次食,不再来了,但贝拉是不同的。treat请客;款待;pity遗憾;praise表扬;rest休息。结合句意可知A项正确。
8.答案与解析:C 考查形容词。结合下文内容可知,几乎贝拉每天都要来到鲁比住所,由此可知,贝拉是与其它三只松鼠有所不同的(different)。
9.答案与解析:B 考查名词。正是因为贝拉与鲁比之间有着很浓厚/强烈的感情(a strng cnnectin),所以贝拉才经常回来看望鲁比。据此可知B项正确。
10.答案与解析:C 考查名词。句意:在过去的十年里,不仅仅是鲁比自己得到了贝拉的陪伴。“贝拉就坐在前门引起他人的注意。”鲁比描述道,“我丈夫从门口冲出来迎接她,然后高兴地跑回屋里给她拿一大碗坚果。”sight视力;景象;眼界;reach范围;延伸;cmpany陪伴;bservatin观察。结合句意可知C项正确。
11.答案与解析:A 考查名词。句意见上一题。attentin注意(力);permissin许可;respect尊敬;interest兴趣爱好。结合句意及下文对鲁比丈夫的描述可知A项正确。
12.答案与解析:B 考查动词。find发现;greet迎接,欢迎;pass穿过,通过;lift提起,提高。此处表示“丈夫被欢迎/迎接”之意。
13.答案与解析:A 考查名词。结合下一句“Bella came rund again with her ________ family.”可知,更加令人感到惊喜的是,贝拉这个春天来的时候带着她的大家庭。
14.答案与解析:D 考查形容词。extended family意为“大家庭/数代同堂的大家庭”,结合空后的内容“with her three babies...”可知答案。
15.答案与解析:C 考查动词(短语)辨析。afraid f害怕;frce逼迫;wait fr等待;apply fr申请。句意:贝拉带着她的大家庭又来了,她的三个孩子正等着有人来注意/关注。结合句意可知C项正确。
Ⅳ.语法填空
【语篇解读】 本文是一篇说明文。文章主要介绍了在英国翻译小说销量上升,对中国小说需求增大。
1.答案与解析:rse 考查时态。根据空后的“last year”可知,此处描述的是发生在过去的事情,应用一般过去时,故填rse。
2.答案与解析:saying 考查非谓语动词。分析句子结构可知,此处作伴随状语,say和句子主语为逻辑上的主谓关系,故填现在分词形式saying。
3.答案与解析:cpies 考查名词的数。cpy此处意为“一册”,为可数名词,根据空前的“mre than 2.6 millin”可知,此处需填其复数形式,故填cpies。
4.答案与解析:were sld 考查动词的时态、语态和主谓一致。分析句子可知,主语为复数形式,谓语动词也应用复数形式,又因为时间是2018年,且谓语动词sell与主语是被动关系,故此处需用一般过去时的被动语态。故填were sld。
5.答案与解析:urselves 考查代词。阅读小说是我们所拥有的最好的换位思考的方式之一。put neself in ther peple's shes“设身处地,处于某人的境地”是固定用法,又由句中的“we”和语境可知,此处应填urselves。
6.答案与解析:hw 考查副词。hungry是形容词,应用副词修饰,又根据语境可知,此处表示被翻译的小说销量的增长表明如此多的英国读者对来自其他国家的优秀文学作品是多么渴望。故填hw。
7.答案与解析:the 考查冠词。对Anna Hlmwd来说,这则消息是“新时代到来”的标志。根据语境可知,这则消息就是上文所讲的中国小说在英国销量好的情况,表示特指。故填the。
8.答案与解析:fr 考查介词。根据语境并分析句子结构可知,此处表示这对于走向国外的中国小说来说,是一个重要的时机。故填fr。
9.答案与解析:translatr 考查名词。根据本句中的“wrked as a literary agent and”可知,空处词性应与agent相同,应填名词形式,又根据语境可知,此处表示Hlmwd作为一名作品经纪人兼译员已经工作9年了。故填translatr。
10.答案与解析:particularly 考查词形转换。修饰介词短语需用副词,故填particular的副词形式particularly。
Ⅴ.书面表达
