Although the northern right whale (Eubalaena glacialis) has remained the most endangered of the world's whale species，we removed it from our Top 10 Endangered Species List a few years back．Because of effective conservation regulations，the number of right whales that travel the Atlantic coasts of Canada and the US had rebounded (回升) from an all-time low of 350 to at least 450 by the middle of the 21st century's second decade．
However，the tide of good news for the species now seems to have been reversed，due，apparently，to global climate change．Warming ocean waters，particularly in the Gulf of Marine where the whales often feed，have caused kill—the tiny creatures right whales feed on—to decrease and become more difficult for the whales to find．As a result，right whale reproduction has fallen to an alarmingly low level，deaths due to all causes have increased，with 16 of the huge cetaceans (鲸) found dead in 2017 alone．Researchers are finding evidence of increased levels of stress on the animals．So alarming is the situation that we've decided to put the northern right whale right back at the top of our list．
The right whale got its name because 19th century whalers considered it “right” whale to kill，as it was not only full of valuable whale oil，but it also floated after it was dead，which made it easy to handle and process．As a result，it was driven to near extinction．Though now protected by law，right whales continue to suffer losses due to commercial fishing—and now，increasingly，as a result of global climate change，due to the lack of the tiny crustaceans (甲壳动物) on which they feed．
4．Why was the northern right whale taken off the Top 10 Endangered Species List for a time
A．Only a few people focused on it．
B．Its population was on the rise again．
C．It wasn't considered as endangered．
D．Many of them settled along Atlantic coasts．
5．What does the underlined word “reversed” in paragraph 2 probably mean
A．Protected．　　　　　　 B．Similar．
C．Opposite． D．Accepted．
6．Why does the author mention 16 dead cetaceans in paragraph 2
A．To stress cetaceans need to be taken seriously．
B．To show oceans got seriously polluted in 2017．
C．To suggest taking measures to protect cetaceans．
D．To warn that cetaceans are on the way to dying out．
7．What can we infer from the last paragraph
A．The tiny crustaceans do harm to the right whales．
B．Commercial fishing has been forbidden for years．
C．The decrease of right whales is related to humans．
D．Climate change results from the number of whales．
Ⅳ．阅读七选五(共5小题；每小题2.5分，满分12.5分)
All living things in the ocean are endangered by humans polluting the water．
1 One way is the dumping (倾倒) of certain waste materials，such as garbage and used water，into the ocean．The harmful bacteria that feed on the garbage use up much of the oxygen in the surrounding water，so other creatures in the area often don't get enough．
Other substances (物质)，such as radioactive waste materials，can also cause pollution． 2 But after years of being exposed to the ocean water，the containers may begin to leak (漏)．
3 Oil is spilled into the ocean when oil ships sink or when oil wells in the ocean cannot be capped．The oil covers the gills (鳃) of fish and prevents them from breathing．Diving birds get the oil on their wings and are unable to fly．When they clean themselves，they are often poisoned by the oil．
Rivers also can contribute to the pollution of oceans． 4 Fertilizers used on the farmlands may be carried to the ocean，where they cause a great increase in the amount of certain plants．Too much of some plants can actually be poisonous to fish．
Worse yet are the pesticides (杀虫剂) carried to the ocean．These chemicals slowly build up in fish and other small animals． 5 The build-up of these chemicals in the animals can make them ill or cause their babies to be born dead or sick．
A．Fish and turtles suffer the most．
B．Pollution occurs in several ways．
C．Oil is another major source of concern．
D．Many rivers receive the run-off water from farmlands．
E．Farmers use these artificial fertilizers to increase crop harvest．
F．These materials are often placed in the water in safely sealed containers．
G．These animals then pass the pesticides on to the larger animals that feed on them．

Ⅲ．【语篇解读】　本文是一篇应用文。文章主要介绍了一些关于种植的活动情况。
1．B　[细节理解题。根据Making Your Own Fertiliser部分中“Duration：2.5 hours”；Plant Care and Growth部分中“Duration：3 hours”；Kids' Garden Adventure部分中“Duration：1.5 hours”；Starting Seeds Workshop部分中“Duration：2 hours”可知，Plant Care and Growth时间最久。故选B。]
2．C　[细节理解题。根据Starting Seeds Workshop中“For those new．．．own food．(对于那些刚接触园艺的人，有一个由经验丰富的园丁布朗夫人主持的讲习班，将介绍基本知识。参与者将学习如何开始播种、照料幼苗，并了解种植自己食物的乐趣。)”可知，布朗夫人在课堂上将教如何种植种子和照料幼苗。故选C。]
3．B　[推理判断题。根据第一段“一年一度的社区花园日是一项珍贵的活动，该活动邀请居民拥抱大自然的美丽。今年，花园将在一个阳光明媚的周六早上开放，提供各种适合所有年龄的活动和园艺技能。”并结合文章主要介绍了一些关于种植的活动情况可知，文章是一则活动指南。故选B。]
【语篇解读】　本文是一篇说明文。文章主要介绍因为气候变暖，曾被移出十大濒危物种名单中首位的露脊鲸现状堪忧。
4．B　[细节理解题。根据第一段第二句“Because of effective conservation regulations．．．by the middle of the 21st century's second decade．” 可知，北露脊鲸被移出十大濒危物种名单的原因是它的数量再次上升。故选B项。]
5．C　[词义猜测题。根据第一段第二句“Because of effective conservation regulations．．．by the middle of the 21st century's second decade．”和画线单词所在句子中的“However，the tide of good news for the species now seems”可知，原本的好消息现在已经不是好消息了，再结合第二段第三句“As a result．．．with 16 of the huge cetaceans found dead in 2017 alone．”可知，露脊鲸的数量在减少，因此好消息已经逆转(与以前相反)了。由此猜测画线词意为“相反的”，与opposite同义。故选C项。]
6．A　[推理判断题。根据第二段最后一句“So alarming is the situation that we've decided to put the northern right whale right back at the top of our list．” 可推知，作者在第二段提到16条死鲸是为了说明鲸类动物需要被严肃对待。故选A项。]
7．C　[推理判断题。根据最后一段前两句“The right whale got its name．．．it was driven to near extinction．”可推知，露脊鲸的减少与人类有关。故选C项。]
Ⅳ．【语篇解读】　本文是一篇说明文。文章主要介绍了海洋面临着人类倾倒的废物，放射性物质，泄漏的石油和河流的污染，海洋中所有生物都会因水被污染而濒临灭绝。
1．B　[设空句下一句“One way．．．”及第二段首句“Other substances．．．”，提示设空句是总领句，总领污染的各种来源、方式，选项B “污染以多种方式发生”是总领句，切题，故选B。]
2．F　[设空句下一句的But，提示设空句是和exposed to相反的情况，选项F中的sealed，是其反义词，符合上下文语境，切题，故选F。]
3．C　[设空句为段首句，本段多次出现了oil这一词汇，根据词汇复现，选项C 切题，故选C。]
4．D　[设空句所在的段落中讲农田里使用的化肥通过河流流入了海洋，其中的farmlands是关键词，选项D中同样有这个关键词，且根据上下文语境，选项D切题，故选D。]
5．G　[设空句前一句有词组small animals，选项G中的larger animals与此对应，讲了杀虫剂污染海洋的过程，选项G切题，故选G。]
