A
Many of Earth’s creatures die because of humans’ choices.These choices have nothing to do with food or shelter or anything else that helps humans survive.What kills millions of animals all over the world is that humans want to make money by doing so.
People use parts of animals for everything from hats to handbags,from jewelry to ashtrays and to make powders that supposedly improve a person’s life.Deciding that a species is endangered and protecting it by law are not always enough.People who kill wildlife illegally rarely get caught.
During the late 1980s,saving elephants became a popular cause.Wildlife protection groups made sure everyone saw pictures or films of elephants with their faces cut off for their ivory.These groups also proved that certain populations of elephants were decreasing.As a result,most people stopped buying objects made of ivory.Laws against poaching(偷猎) were made stronger.Many countries made importing ivory illegal.Killing elephants for their ivory became more risky and less profitable(有利可图的).
However,concern for certain species will become weak after a while.In the late 1970s,people protested (抗议) against the killing of seal babies.Everyone was shocked to see young seals being killed in their icy habitat.The cruel activity stopped.But ten years later,the number of seal babies killed was higher than ever.
Other animal protection movements have come and gone,such as saving the whales and protecting dolphins.The whale population appears to have increased for now.And the laws are finally changed in America to protect the dolphins that swim with tuna fish in parts of the Pacific Ocean.
In the years to come,people’s attention will probably turn to some other endangered species.Plenty of them urgently need attention.During this time,will the elephants be forgotten
1.What leads to the disappearance of millions of wild animals
A.The growing human population.
B.Humans’ hope for making a fortune.
C.Humans’ too much need for wild food.
D.Not having enough laws on wildlife protection.
2.What can we infer from the text about what happened in the late 1980s
A.Wildlife protection groups did make great efforts.
B.Importing ivory in all countries is illegal.
C.Those who killed elephants all got caught.
D.Hunting was completely not allowed.
3.Why are seal babies mentioned in paragraph 4
A.To show the effort to protect seal babies.
B.To show an increasing number of seal babies.
C.To show the decrease of worry about certain species.
D.To show people’s protest against the killing of seal babies.
4.What does the author mean by using the underlined sentence
A.Humans should choose some rare animals to protect.
B.Attention must be paid to saving some endangered wildlife.
C.Success has been achieved in quite a few cases of wildlife protection.
D.Concern and movements for animal protection should be always kept.
B
Nature has created many ways to protect creatures’ eyes.The most common protection is the eyelid—a fold of skin that closes over the eye,protecting it from damage.Eyelashes are useful for keeping out dust and other things,and tears wash away any small pieces that get through the other defenses.
Some creatures,including most birds,have three eyelids.The upper and lower lids act like human lids and keep out little tree branches,dirt,and sand.The third eyelid,however,is a semitransparent tissue(半透明组织) that crosses over the eye from the inside corner to the outside corner.Because of this protective membrane(隔膜),birds seldom have to blink.They close their eyes only when they go to sleep.For ducks,this third eyelid serves as an underwater diving mask that helps the ducks find food.
Most fish and snakes have no eyelids at all.Instead,a hard glassy covering protects their eyes.For fish,water constantly sweeps away dirt from the covering.And a snake’s eyesight is usually so bad that a little dirt obscuring its vision does not disturb it greatly.
Eyelashes defend(保护) the eye by shading it from strong light.They also act like mini brushes to remove dust.Camels have eyelashes that are four inches long to protect their eyes from wind-blown sand in the desert.
5.Why don’t birds blink often
A.They don’t need to sleep a lot.
B.Their upper and lower lids can keep away little branches,dirt and sand.
C.Eyelashes act like mini brushes to remove dust.
D.They have a kind of tissue to cover the eyes.
6.Which of the following statements is TRUE according to this passage
A.Ducks don’t close their eyes even when they go to sleep.
B.A little dirt doesn’t disturb a snake’s eyesight badly because its eyesight is very good.
C.Eyelashes help to keep away small pieces that get through the other two defenses.
D.Some creatures have a hard covering to protect their eyes instead of eyelids.
7.What can be concluded from the passage
A.Eyelids are more important in protecting creatures’ eyes than other devices.
B.Creatures develop different modes of eye protection in different environments.
C.Birds often close their eyes in the daytime.
D.A fish’s eyelid is a hard glassy covering.

Be a Green Guest
When people take a vacation,they often take a vacation from responsibility,too.Our behavior at hotels is one of the biggest problems.We have our linen(亚麻织品) washed daily for us,and are provided with an endless stream of hot water.But all of this luxury equals serious consequences for the environment. 1 .They offer programs and facilities that save water and energy.That’s a good start,but there is a lot more you can do to cut down the amount of waste produced.
2 .
In America alone,there are about 50,000 hotels.Now think if hotel management puts two small bottles for each hotel room every day,that’s a huge amount of little plastic bottles that may not even get recycled.And what about all of that shampoo when you don’t finish the bottle A better way is to bring your own shampoo from home.
Turn off the lights.
You do it when you’re at home,right Do it at the hotel,too.Studies have shown that,in hotels,the majority of energy spent through lighting comes from the bathroom light being left on for more than one hour! 3 ,remember to hit the switch!
Don’t have your sheets or towels washed every day.
Sure,it’s luxury to have linen and towels cleaned every day,but that’s all it is.Washing a set of bed sheets and a pair of bathroom towels requires about 12-16 gallons of water.See if there is a policy for requesting that your towels and linen get washed weekly.In some hotels,it’s as simple as hanging towels back up on a hook. 4 .
These tips are also useful for trips to a friend’s or relative’s house. 5 .They will also save your hosts a lot of money.
A.Think about bathroom facilities
B.Just say “no” to hotel shampoo
C.When you’re using the bathroom
D.After you’re done with your business
E.They will save plastic,water,and electricity
F.More and more hotels are becoming eco-friendly
G.In others,you may ask the front desk for a personal request
Ⅶ.完形填空
For many years,I was so wrapped up in my kids and my family that I ignored how I looked.The words “ 1 maintenance” described my approach to beauty perfectly.
It wasn’t until recently,when I had my picture taken for a work ID,that I 2 the “Youth Train” had left the station,and I was no longer on it.The woman in the ID picture looked 3 and definitely middle-aged.
For a few days,I was a little 4 by the fact that I was no longer the sweet,young thing I thought I was.For those few days,I tried a little harder to 5 younger,brighter and tighter.I even 6 my hair and added extra eyeliner.
I thought I was 7 in my seeking for a youthful glow until one of my new co-workers 8 asked me a question that told me I was 9 only myself.“I don’t suppose you know what beauty is,do you ” she asked.
That simple question opened my weary eyes once and for all.My family 10 me not for my no-longer-shiny hair but because the 11 I’m playing,that is my husband’s wife and my kids’ mom.
Someone once said that 12 is the first gift given and the first one taken away.I agree but only when it comes to 13 beauty.When it comes to staying young,a mind-lift 14 a face-lift any day.The 15 beauty,the stuff inside that all of us have,lasts a lifetime.

Ⅴ.【语篇解读】本文是一篇说明文。作者呼吁对动物保护的关注和行动应该持续下去。
1.B 细节理解题。根据第一段最后一句“What kills millions of animals all over the world is that humans want to make money by doing so.”可知,人类的贪欲导致数百万野生动物的消失。故选B项。
2.A 推理判断题。根据第三段可知,在20世纪80年代末,野生动物保护组织确实为保护大象做出了巨大努力。故选A项。
3.C 细节理解题。根据第四段第一句“However,concern for certain species will become weak after a while.”可知,第四段提到了海豹宝宝,目的是表明对某些物种担忧的减少。故选C项。
4.D 句意理解题。根据倒数第二段中的“Other animal protection movements have come and gone...”和最后一段第一句“In the years to come,people’s attention will probably turn to some other endangered species.”可以推断,作者说这句话的意思是,对动物保护的关注和行动应该持续下去。故选D项。
【语篇解读】本文是一篇说明文。大自然创造了许多方法来保护动物的眼睛。
5.D 细节理解题。根据第二段中的“The third eyelid,however,is a semitransparent tissue that crosses over the eye from the inside corner to the outside corner.Because of this protective membrane,birds seldom have to blink.”可知,鸟类不常眨眼是因为它们有一种覆盖眼睛的组织。故选D项。
6.D 细节理解题。由第三段第一、二句可知,大多数鱼和蛇没有眼睑,取而代之的是一层坚硬的玻璃状的覆盖物,用以保护它们的眼睛,这与D项相符合。
7.B 推理判断题。由文中的“Some creatures,including most birds,have three eyelids.”,“Most fish and snakes have no eyelids at all.Instead,a hard glassy covering protects their eyes.”以及“Camels have eyelashes that are four inches long to protect their eyes from wind-blown sand in the desert.”可知,有些生物,包括大多数鸟类,有三个眼睑。大多数鱼和蛇根本没有眼睑,取而代之的是一层坚硬的玻璃状的覆盖物,用以保护它们的眼睛。骆驼的睫毛有四英寸长,可以保护眼睛免受沙漠中风沙的侵袭。由此推断出生物在不同的环境中进化出不同的护眼模式。
Ⅵ.【语篇解读】本文是一篇说明文。文章主要讲述了人们在外出住酒店时可以通过很多方式减少污染、节约能源、保护环境。
1.F 根据空后一句“They offer programs and facilities that save water and energy.”可知,they指代的应该是hotels,再结合空前一句中的“all of this luxury equals serious consequences for the environment”可知,空处应该会讲到酒店已经意识到环境问题并开始行动,故F项符合语境。

A
A new study has found that North American migratory(迁徙的) birds have been getting smaller over the past 40 years.Researchers say the finding suggests a warming climate(气候) could be affecting bird growth in North America—and across the world.
The study was recently published in Ecology Letters.Researchers measured(测量) the size of 80,000 birds killed from 1978 to 2016 during the spring and fall migrations in the city of Chicago,Illinois.Over the 40-year period,body size decreased in all 52 species.The average body weight fell by 2.6 percent.Leg bone length dropped by 2.4 percent.The one area of growth was the wingspan,which increased by 1.3 percent.
The researchers said the wing growth likely happened to allow the birds to continue making long migrations with smaller bodies.The study considered a principle known as Bergmann’s rule,in which individuals within a species grow smaller in warmer areas and grow larger in colder ones.
Brian Weeks,a biologist at the University of Michigan’s School for Environment and Sustainability,helped lead the research.He said that he believes the results show a clear connection between a warming climate and the growth of the birds.“In other words,climate change seems to be changing both the size and shape of these species,” he said.
The study found a direct connection between the average summer temperature and the body size of the birds.Dave Willard works with Chicago’s Field Museum,which was in charge of measuring all the birds.He said nearly “everyone agrees that the climate is warming,but examples of just how that is affecting the natural world are only now coming to light.”
“We had good reason to expect that increasing temperatures would lead to reductions in body size,based on earlier studies,” Weeks said.“I was incredibly surprised that all of these species are responding in such similar ways.”
The researchers plan to continue studying the Field Museum data in an effort to find additional evidence to support their findings.They will also further examine the idea that an individual’s physical development can change to fit changing environmental conditions.
1.Which of the following didn’t go down to a lower level
A.The body size. B.The body weight.
C.The leg bone length. D.The wingspan.
2.Which of the following took responsibility for measuring the birds
A.Ecology Letters. B.Brian Weeks.
C.The Field Museum. D.Dave Willard.
3.What do the underlined words “coming to light” in paragraph 5 mean
A.Known. B.Similar.
C.Intelligent. D.Distant.
4.The main idea of the passage is that .
A.fifty-two species of birds became smaller
B.the warming climate could affect bird growth
C.the warming climate makes the birds grow larger
D.the researchers have proved their findings
B
In the past 50 years,the amount of water in the open ocean with zero oxygen has gone up more than fourfold.In coastal water bodies,including river mouths and seas,low-oxygen sites have increased more than tenfold since 1950.Scientists expect oxygen to continue dropping even outside these zones as Earth warms.
“Oxygen is fundamental to life in the Oceans,” said Denise Breitburg,a marine ecologist with the Smithsonian Environmental Research Centre.“The decline in ocean oxygen ranks among the most serious effects of human activities on the Earth’s environment.Actually,it’s a great loss to all the support services that rely on recreation and tourism,including hotels and restaurants and taxi drivers and everything else.The reverberations(严重影响) of unhealthy ecosystems in the ocean can be extensive.”
In areas traditionally called “dead zones”,like those in Chesapeake Bay and the Gulf of Mexico,oxygen plummets(大幅下跌) to so low levels that many animals die.As fish avoid these zones,their habitats become smaller and they’re easier to be attacked or caught.But the problem goes far beyond “dead zones”.Even smaller oxygen decline can prevent growth in animals,hinder reproduction and lead to disease or even death.It can also cause the release of dangerous chemicals such as nitrous oxide,a greenhouse gas up to 300 times more powerful than carbon dioxide.While some animals can boom in “dead zones”,overall biodiversity falls.
Climate change is the key criminal in the open ocean.Warming surface waters make it harder for oxygen to reach the inside of the ocean.Furthermore,as the ocean as a whole gets warmer,it holds less oxygen.In coastal waters,too much nutrient pollution from land creates algal blooms,which use up oxygen as they die and break down.
People’s livelihoods are also on the line,the scientists reported,especially in developing nations.Smaller fisheries(渔场) may be unable to relocate when low oxygen destroys their harvests or forces fish to move elsewhere.So we humans have to carry on a war now and win the war.
5.What does the first paragraph mainly talk about
A.The ocean has been losing its oxygen.
B.The amount of sea water is increasing.
C.The coastal water bodies are dangerous.
D.Earth becomes warmer and warmer.
6.What can we infer from Denise Breitburg’s words
A.Different oceans have different levels of oxygen.
B.The decline in ocean oxygen has great influences.
C.The future of tourism relies on the levels of ocean oxygen.
D.The decrease in ocean oxygen is the most serious environmental problem.
7.How does the “dead zone” affect sea animals
A.It offers more food.
B.It forms dangerous gas.
C.It reduces their living areas.
D.It produces more carbon dioxide.
8.How can we win the war according to the text
A.By closing smaller fisheries.
B.By controlling humans’ bad activities.
C.By improving people’s living standards.
D.By stopping nutrients entering the ocean.
Ⅵ.七选五
All living things in the ocean are endangered by human’s 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 material,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(腮) 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 buildup 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 runoff 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.

3.A 词义猜测题。根据第六段中的“We had good reason to expect that increasing temperatures would lead to reductions in body size,based on earlier studies”可知,画线短语所在句指的是每个人都同意气候正在变暖,但关于气候变暖如何影响自然界的例子直到现在才为人所知。画线部分的意思是“(被)知道”。故选A项。
4.B 主旨大意题。根据第一段中的“Researchers say the finding suggests a warming climate could be affecting bird growth in North America—and across the world.” 可知,研究人员表示,这一发现表明气候变暖可能会影响北美乃至全球的鸟类生长,由此可知本文的主要观点是气候变暖会影响鸟类的生长。故选B项。
【语篇解读】本文是一篇说明文。人类活动导致全球变暖,气候变化影响海洋生物的生存,这些会相应地影响人类的生存,人类必须采取措施应对此问题。
5.A 段落大意题。通过第一段可知海洋面临的现状,在过去的50年里,海洋中零氧水域的水量增加了四倍多,低氧地区自1950年以来增加了十倍多。科学家预计,随着地球变暖,即使在这些区域之外,氧气含量也会继续下降。故选A项。

Swimming in the water of Hawaii’s Big Island is a fun experience.But it can be more exciting if there are dolphins swimming around and jumping out of the sea too.For many people,it would be a wonderful dream to swim with these lovely animals!However,this may not be good for dolphins.They may get hurt because of human interaction(互动).
Dolphins are active and usually look for food at night.In the day,they like to rest in shallow bays(浅湾).Many people think the dolphins are awake during the day as they swim.But when they sleep they rest half of their brain and keep the other half awake to breathe,so they may be sleeping even when they’re swimming in the water.
From 2010 to 2013,spinner dolphins(飞旋海豚) of Hawaii’s Big Island were exposed to human activities more than 82 percent of the time,according to Julian Tyne,a researcher at Australia’s Murdoch University.
The National Oceanic and Atmospheric Administration (NOAA) says disturbing the animals in their near-shore habitat could force them to swim to less favourable places,putting them at risk of being attacked by sharks and other animals.
Besides,when people are around,dolphins become more active.Thus,they can’t get enough sleep.“Disturbing their resting behaviours can actually affect their long-term health and the health of the dolphin population,” Ann Garrett of NOAA’s National Marine Fisheries Service told the Associated Press.
As a result,the NOAA wants to make rules to help protect the dolphins.For example,the agency(机构) may ban swimming with the Hawaii spinner dolphins.Or they may stop people from swimming in shallow bays when the dolphins are resting.Tour operators must also be taught to watch for signs to know when the dolphins are in their resting state.
1.Which of the following about dolphins is NOT true
A.They spend most of their time sleeping at night.
B.They like to stay in shallow bays during the day.
C.They keep half of their brain awake while sleeping.
D.They may be sleeping even when they’re swimming.
2.What would they do when dolphins are disturbed in their near-shore habitat
A.Swim to a crowded place.
B.Move closer to sharks.
C.Become less active.
D.Likely sleep longer.
3.Which activity is against the rules
A.Swimming with the Hawaii spinner dolphins.
B.Swimming in bays where the dolphins live.
C.Making signs that show the dolphins’ resting state.
D.Making signs that show where the dolphins are.
4.What does the article mainly talk about
A.What habits dolphins have.
B.What spinner dolphins are.
C.How the animals live in the sea.
D.How to protect dolphins near the shore.

When you were trying to figure out what to buy for the environmentalist on your holiday list,fur probably didn’t cross your mind.But some ecologists and fashion(时装) enthusiasts are trying to bring back the market for fur made from nutria(海狸鼠).
Unusual fashion shows in New Orleans and Brooklyn have showcased nutria fur made into clothes in different styles.“It sounds crazy to talk about guilt-free fur—unless you understand that the nutria are destroying vast wetlands every year,”says Cree McCree,project director of Righteous Fur.
Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail.Some of the fur ends up in the fashion shows like the one in Brooklyn last month.
Nutria were brought there from Argentina by fur farmers and let go into the wild.“The ecosystem down there can’t handle this non-native species(物种).It’s destroying the environment.It’s them or us,”says Michael Massimi,an expert in this field.
The fur trade kept nutria in check for decades,but when the market for nutria collapsed in the late 1980s,the cat-sized animals multiplied like crazy.
Biologist Edmond Mouton runs the nutria control program for Louisiana.He says it’s not easy to convince people that nutria fur is green,but he has no doubt about it.Hunters bring in more than 300,000 nutria tails a year,so part of Mouton’s job these days is trying to promote fur.
Then there’s Righteous Fur and its unusual fashions.Model Paige Morgan says,“To give people a guilt-free option that they can wear without someone throwing paint on them—I think that’s going to be a massive thing,at least here in New York.”Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable.She’s trying to come up with a label to attach to nutria fashions to show it is eco-friendly.
5.What is the purpose of the fashion shows in New Orleans and Brooklyn
A.To promote guilt-free fur.
B.To expand the fashion market.
C.To introduce a new brand.
D.To celebrate a winter holiday.
6.Why are scientists concerned about nutria
A.Nutria damage the ecosystem seriously.
B.Nutria are an endangered species.
C.Nutria hurt local cat-sized animals.
D.Nutria are illegally hunted.
7.What does the underlined word “collapsed” in paragraph 5 probably mean
A.Boomed. B.Became mature.
C.Remained stable. D.Crashed.
8.What can we infer about wearing fur in New York according to Morgan
A.It’s formal. B.It’s risky.
C.It’s harmful. D.It’s traditional.
Ⅵ.七选五
Imagine mountains enveloped in silver water,shining in the spring sun.Summer sees the mountains turn green.During autumn,these mountains are gold,and in winter they are covered with white snow. 1
These terraces (梯田) were built by the local Zhuang and Yao people.Starting in the Yuan Dynasty,work on the terraces took hundreds of years. 2 Reaching as far as the eyes can see,these terraces cover tall mountains,often from the bottom to the very top.
3 Firstly,there are few large flat areas of land in the region.Building the terraces could increase the areas to grow rice.Secondly,although the region has plenty of rain,the mountains are steep(陡峭) and the soil is shallow.The fat terraces help catch the rainwater and prevent the soil from being washed away.
But perhaps the most important is the way people have worked in peace with nature.The terraces are cleverly designed,with hundreds of waterways connecting with each other.During the rainy season,rainwater moves down the mountains and into the terraces along these waterways.The sun heats the water and turns it into vapour (水蒸气). 4 These terraces also provide a perfect environment for birds and fish,some of which feed on insects harmful to crops.
Although modern technology helps produce more crops,these terraces still mean a lot to the local people for whom traditions hold much value. 5 Thus,new generations continue to use ancient methods of agriculture to maintain the terraces.Today,the Longji Terraces attract thousands of visitors to admire this great wonder created by people and nature working together.
A.Terraces were built to collect the rain.
B.These are the colours of the Longji Terraces.
C.This knowledge is passed down through families.
D.It wasn’t completed until the early Qing Dynasty.
E.So how did people change the entire mountains into terraces
F.This forms clouds from which rain falls down onto the terraces again.
G.So why did these people take trouble turning the entire mountains into terraces

2.B 细节理解题。根据文章第四段中的“disturbing the animals in their near-shore habitat could force them to swim to less favourable places,putting them at risk of being attacked by sharks and other animals.” 可知,妨碍海豚在近岸栖息可能迫使它们游向不合适的地方,可能会遭受鲨鱼和其他动物的袭击,故选B项。
3.A 细节理解题。根据最后一段中的“the agency may ban swimming with the Hawaii spinner dolphins.”可知,与夏威夷飞旋海豚一起游泳是被禁止的,故选A项。
4.D 主旨大意题。本文前面部分介绍了海豚,后面主要是号召人们保护海豚,以及如何保护的问题,故选D项。
【语篇解读】本文是一篇说明文。海狸鼠对生态系统造成了严重的破坏,因此科学家们鼓励人们捕猎海狸鼠,并把它们的毛皮制成时装。
5.A 推理判断题。根据第二段内容可知,在这两个城市举办的时装展不同寻常,如果了解了背后的原因,人们就不必因为穿着用动物毛皮制作的衣服而感到内疚。由此推断出,时装展的目的是宣传推广用海狸鼠的毛皮制成的时装。故选A项。
6.A 细节理解题。根据第四段内容可知,科学家们之所以关心海狸鼠,是因为它们严重破坏了当地的生态系统。故选A项。
7.D 词义猜测题。根据画线词所在句的句意,尤其是but前面出现的短语keep sth in check“将……控制住”可推断出,该画线词意为“崩溃;暴跌;倒闭”。故选D项。
8.B 推理判断题。根据最后一段中Morgan所说的话可以推断出,在纽约,穿皮草是一件很冒险的事情,因为可能会有人往你身上泼油漆。故选B项。
Ⅵ.【语篇解读】本文是一篇说明文。文章主要介绍了龙脊梯田的建造历史、作用和现状。
1.B 根据上文“Summer sees the mountains turn green.During autumn,these mountains are gold,and in winter they are covered with white snow.”可知,上文介绍了山峦在不同季节呈现出的不同颜色。B项“这些是龙脊梯田的颜色。”能够承接上文;上文提到的“绿色”和“金色”等,是龙脊梯田在不同季节呈现出的颜色。最后一段中的“the Longji Terraces”也是提示。故选B项。
2.D 根据上文“Starting in the Yuan Dynasty,work on the terraces took hundreds of years.”可知,上文介绍了龙脊梯田的建造时间。D项承接上文,说明龙脊梯田从元朝开始建造,耗时数百年,直到清初才建成。故选D项。
3.G 根据下文“Firstly,there are few large flat areas of land in the region.Building the terraces could increase the areas to grow rice.”可知,下文介绍了建造龙脊梯田的原因——可以增加水稻种植面积。G项“那么为什么这些人要费力把整座山变成梯田呢 ”提出的问题正好对应下文给出的原因。故选G项。
4.F 根据上文“During the rainy season,rainwater moves down the mountains and into the terraces along these waterways.The sun heats the water and turns it into vapour.”可知,上文介绍了龙脊梯田是如何利用雨水的。F项“这就形成了云层,雨水从云层中再次降落到梯田上。”承接上文,进一步解释了龙脊梯田是如何利用雨水的。雨水沿着水道进入梯田,太阳加热水,使其变成水蒸气,水蒸气形成了云层,雨水从云层中再次降落到梯田上,形成了循环利用的模式。故选F项。
5.C 根据上文“Although modern technology helps produce more crops,these terraces still mean a lot to the local people for whom traditions hold much value.”可知,上文说明了龙脊梯田对当地人来说很有价值。C项“这种知识是通过家庭流传下来的。”承接上文,正因为龙脊梯田对当地人来说很有价值,所以种植梯田的知识才会通过家庭流传下来;同时,C项也引起下文,因为种植梯田的知识通过家庭流传下来了,所以,新一代人继续使用古老的农业方法来维护梯田。故选C项。
