21、 Deciduous forests(落叶林) are home to many wild animals. The development and expansion of human presence in the forests has caused many of their native species to become endangered.
Giant Panda
The giant panda, one of the most recognizable endangered species, is a large, docile species of bear native to the deciduous forest of eastern China, Myanmar and Vietnam. Because of its lim-ited diet— the panda’ s main source of food is bamboo— the species is limited in its habitat to areas where bamboo is available. Now the species only can be found today in 20 small patches of forest at the western edge of its historic range.
Gray and Red Wolves
The gray wolf, which once ranged from the East Coast of America to the West, and south to Mexico, now has a population of only 5, 000 in the lower 48 states, mostly in the Rocky Mountains. The smaller red wolf, native to the southeastern United States, was declared extinct in the wild in 1980, though conservation efforts have reintroduced small captive populations to the wild in California.
Red-Crowned Crane
The red-crowned crane is native to Japan, Korea and eastern China. Agricultural expansion and deforestation (森林砍伐) in these areas have removed a great deal of the marshes and forests that are the crane’ s primary habitats. For a time, the crane was thought to have completely disappeared from Japan, but the recent discovery of cranes in Japanese marshlands has restarted conservation efforts. Today, around 2, 500 cranes live in the wild, including 1,000 in Japan.
European Mink
Native to Europe, the European mink ranges from France in the west to Finland in the north, Russia in the east and the Balkans in the south. Destruction of the mink’ s aquatic (水的) habitat and use of the species for fur have caused dramatic drops in the species’ population, which has been reduced by 85 percent since the mid-19th century.
【1】What has caused the wild animals to become endangered?
A.Global warming. B.International trade.
C.Environmental pollution. D.The invasion of mankind.
【2】Which species is native to North America?

【3】Which is mentioned as the reason for the decline of European minks?
A.The loss of their natural food. B.The hunting of human beings.
C.Drought and forest fires. D.Excessive deforestation.
【4】What is the purpose of the text?
A.To call for more efforts to protect forests.
B.To study the living habits of wild animals.
C.To introduce some endangered species.
D.To find ways to protect wild animals.
22、Ways to Worry Less
Do you want to worry less? Of course you do. That's like asking if I can send you free bacon . Worry is like black mold----it appears in damp conditions and spreads uncontrollably. And very often we don't realize it's there until it's killing us. We must get rid of worry before it destroys us. But how should we do it? 【1】
Do what you need to do.
【2】You ought not to avoid tough projects or hard conversations. If you don't do what you should be doing, you will end up spending the rest of the time worrying about the must-do things. Believe it or not, the anxiety that comes from the worry is much worse than the task we're worried about.
【3】
I think many of us act like we're puppets (木偶)in a play and we're waiting for something or someone to put us in the right place. We just react to whatever is going on.【4】We need to live purposefully . Nothing can cause more worry than purposelessness.
Make plans.
You can't succeed without making plans. Making plans will enable you to achieve your aims more smoothly. However, your plans aren't set in stone. You can adjust your plans flexibly. Accept changes.【5】
There are other ways to lessen worry. As long as you are determined to take action, you will live a worry-free life.
A. Get more purposeful.
B. Worry ruins creativity.
C. Do what you should be doing.
D. We need to stop letting life just happen.
E. Make new plans and then move forward.
F. Here are some effective ways to deal with it.
G. You do the same things as the people around you do.
23、Ford is turning McDonald’s coffee waste into headlights
Ford is recently including coffee chaff (谷壳) that comes off during the roasting process—into the plastic headlights housing (大灯外壳) used in some cars. It has asked McDonald’s, which doesn’t roast its own coffee, to connect it with suppliers.
In recent years, as consumers feel more concern for plastic pollution and carbon emissions, companies have made full commitments to reduce their influences on the environment. They’ve also been developing new, sustainable materials to build consumer products.
Traditionally, Ford uses plastic and talc(滑石粉) to make its headlights housing. The coffee version is more sustainable because it’s lighter and doesn’t use the talc which, as a mineral, isn’t renewable. Coffee chaff, on the other hand, is widely available, and much of it goes to waste. Eventually, Ford hopes to use the material for more parts.
Ford decided to work with coffee chaff a few years ago. But it’s been experimenting with organic materials for over a decade. The auto company has been using soy-based foam(泡沫) in its cushions since 2011. It also uses waste from wheat, coconut, tomato and other plants in its cars in order to help meet some of its sustainability goals, which include using more renewable materials. Once the Ford team figured out how coffee chaff could be used to build car parts, it reached out to McDonald’s because of the restaurant chain ‘s scale and its sustainability goals. Like Ford, McDonald’s also wants to bring renewable and recycled materials into its products. The partnership between Ford and McDonald’s is an example of how brands with different projects can work together.
“We’ve conventionally thought of cooperation as within the food industry,” said Lan Olson, senior director of Global Sustainability at McDonald’s. “The Ford partnership can help McDonald’s see what kind of larger impacts are possible when it works with a company in another field. This is just scratching(划开) the surface of trying to understand what’s possible,” Olson said.
【1】Why is Ford applying coffee chaff to headlights housing?
A.To work with McDonald’s.
B.To do experiments in the lab.
C.To save resources and money.
D.To reduce environmental pollution.
【2】What makes Ford choose McDonald’s as its partner?
A.Coffee of McDonald’s is so popular and has great potential.
B.Ford wants to cooperate with one in the food industry.
C.They have the same sustainability goals.
D.Different brands with different projects can work together.
【3】What can we learn from Olson’s words?
A.Cooperation between the two brands just begins.
B.The cooperation is only on the surface.
C.Ford has a large influence on McDonald’s.
D.Only cooperation within the food industry is welcomed.
【4】In which section of a newspaper may this text appear?
A.News.
B.Business.
C.Science.
D.Entertainment.
24、 How does an ecosystem work? What makes the population of different species the way they are? Why are there so many flies and so few wolves? To find an answer, scientists have built mathematical models of food webs, noting who eats whom and how much each one eats.
With such models, scientists have found out some key principles operating in food webs. Most food webs, for instance, consist of many weak links rather than a few strong ones. When a predator always eats huge numbers of a single prey, the two species are strongly linked; when a predator lives on various species, they are weakly linked. Food webs may be dominated by many weak links because that arrangement is more stable over the long term. If a predator can eat several species, it can survive the extinction of one of them. And if a predator can move on to another species that is easier to find when a prey species becomes rare, the switch allows the original prey to recover. The weak links may thus keep species from driving one another to extinction.
Mathematical models have also revealed that food webs maybe unstable, where small changes of top predators can lead to big effects throughout entire ecosystems. In the 1960s, scientists proposed that predators at the top of a food web had a surprising amount of control over the size of populations of other species—including species they did not directly attack.
And unplanned human activities have proved the idea of top-down control by top predators to be true. In the ocean, we fished for top predators such as cod on an industrial scale, while on land, we killed off large predators such as wolves. These actions have greatly affected the ecological balance.
Scientists have built an early-warning system based on mathematical models. Ideally, the system would tell us when to breakdown or would even allow us to pull an ecosystem back from the borderline. Prevention is key, scientists say, because once ecosystems pass their tipping point, it is remarkably difficult for them to return.
【1】What have scientists discovered with the help of mathematical models of food webs?
A.The living habits of species in food webs.
B.The rules governing food webs of the ecosystems.
C.The approaches to studying the species in the ecosystems.
D.The differences between weak and strong links in food webs.
【2】A strong link is found between two species when a predator ________.
A.has a wide fond choice
B.can easily find new prey
C.sticks to one prey species
D.can quickly move to another place
【3】What will happen if the populations of top predators in a food web greatly decline?
A.The prey species they directly attack will die out.
B.The species they indirectly attack will turn into top predators.
C.The living environment of other species will remain unchanged.
D.The populations of other species will experience unexpected changes.
【4】What conclusion can be drawn from the examples in Paragraph 4?
A.Uncontrolled human activities greatly upset ecosystems.
B.Rapid economic development threatens animal habitats.
C.Species of commercial value dominate other species.
D.Industrial activities help keep food webs stable.
