1 . An earthquake can strike without warning. But many injuries and deaths from this kind of natural disaster can be prevented if people follow these safety tips.

If you’re inside a building, stay there! One of the most dangerous things to do in an earthquake is to try to leave a building.     1     Drop down onto the ground. Get under an object that is not easily damaged. Hold on to it until the shaking stops. You can also get to a corner formed by two walls with your arms over your head. If you’re in bed when the quake hits, stay there and protect your head with a pillow.

    2     Don’t take shelter under trees, streetlights, telegraph poles or tall buildings. If you are driving stop as quickly as possible and stay away from overpasses, buildings, bridges or anything else that might fall or collapse over you.     3    

If you are trapped in the ruins, cover your mouth with a handkerchief or a piece of clothing. Use your cellphone to call for help if possible. Don’t shout.     4     Tap on a pipe or the wall so rescuers can find you.

Be prepared for aftershocks    5     However, sometimes they even happen months later. Therefore, if you are not in a safe position after the first shock, you should move quickly but carefully to a safer place.

A．Don’t move about or kick up dost.

B．If you’re outside, go to an open space.

C．Shouting can cause you to breathe in dust.

D．Don’t park your car under a tree or any tall object.

E．Take a good hold of your cellphone in the building.

F．They can happen in the first hours after the earthquake.

G．Most injuries happen when people inside buildings try to get out.

2 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.

Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.

The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.

As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.

The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

3 . Tips for Green Travel with Kids

Travelling doesn’t mean letting go of all the eco-friendly choices we work so hard to achieve in our daily life. Here are a few tips for green travel with kids.

Booking nonstop flights whenever possible will reduce carbon emissions (碳排放). If the closest local airport doesn’t have nonstop flights to a certain place, check with other local airports to see if nonstop flights are available.     1    

It’s easy when travelling to pull in to fast food restaurants for snacks.     2     My kids love to help plan snacks. I let them create their own snacks for the trip at home.

    3     At the airport, keep your reusable bottles empty until you have passed through the security (机场安检区). Fill them up on the other side of the security checkpoint. Single-use plastic water bottles create unnecessary waste and the plastic can be harmful to your health.

    4     In addition, opening a few windows and turning off the air conditioner (空调) are also good ways to save energy. You should also help your children keep their good, green habits while travelling. Sometimes vacation can mean more than one shower each day-once in the morning and again after getting out of the pool. Pay attention to the number of showers (淋浴) and the length of showers.     5    

A．Walking is good for your health.

B．Try to cut back to save water and energy.

C．But you can pack healthy food from home.

D．Travelling is a great chance to introduce your kids to the world.

E．Reusable water bottles are easy to bring along wherever you travel.

F．Save energy by turning off the hotel room lights when you head out for the day.

G．You might have to drive a bit farther, but saving on carbon emissions makes it worthwhile.

6 . The endangered pandas in the Qinling Mountains might face a new threat: the loss of their food, bamboo, which makes up 99% of their meals.

Adult pandas spend most part of the day eating bamboo and have to take in at least 40 pounds a day to stay healthy. However, a new study published in Nature Climate Change warned that they may soon find their food gone because most of the bamboo in the Qinling Mountains might disappear by the end of the century as a result of rising temperature worldwide.

A team made up of researchers from Michigan State University and the Chinese Academy of Sciences has studied the effects of climate change on the bamboo in the Qinling Mountains. They have found that bamboo is very sensitive to climate changes. “80% to 100% of the bamboo would be gone if the average temperature rises 3.5 degrees worldwide by the end of the century,” said Liu Jianguo, one of the report’s authors.

He added, “This is how much the temperature would rise by 2100 even if all countries will keep their promises in the Paris Agreement. But you know what is happening all around the world.”

In recent years, China has been trying its best to protect the endangered pandas by setting up more and bigger natural reserves.

“But it is far from enough and the endangered pandas need cooperation from the rest of the world, because their future is not just in the hands of the Chinese,” said Shirley Martin from the World Wildlife Fund but not a member of the team.

The Qinling Mountains, in the southwest of China, are home to about 260 pandas. That is about 13% of China’s wild panda population. In addition, about 375 are living in research centers and zoos in China.

8 . Scientists say a huge percentage of bird species are in danger because their habitats, or homelands, are disappearing.

Traditional migration paths take birds through countries that are not protecting the places for birds to stop, rest and feed. The scientists studied the migration or flight paths of almost 1,500 species. They decided that 91 percent of them passed through dangerous areas.

The major danger for migratory birds is development. Buildings and pavements have covered the places where birds stop and feed as they move from one part of the world to another. One of the scientists who worked on the study says “Many of these important places have been lost to land reclamation because of urban, industrial and agricultural land expansion”.

The problem, according to scientists, is that many of these small birds die along their migration paths because they don’t have a safe place to feed and rest. There is no place to restore their energy for the next part of their journey. Countries in North Africa, Central Asia and those along the coasts of East Asia are having the most difficult time in protecting land. The scientists say these countries do not have enough areas that are safe for birds. One species that doesn’t exist now is the Eskimo curlew. “Our world gets poorer every time we lose a species,” one of the scientists says.

The researchers say countries need to work together and come up with safe stopping areas for birds that pass through their boundaries. For example, one country might have preserved safe zones for migrating birds. But a neighbor country might not. A bird might die.

One scientist who is not connected with the report tells Los Angeles Times that while some habitats are changing, more work can be done to make urban areas safe for birds.

He says small changes, like planting more native plants or keeping cats out of the areas birds would be likely to use, could make a big difference.

A．By keeping fewer cats or dogs.

B．By restoring their destroyed habitats.

C．By helping change the birds’ migration paths.

D．By preserving the ecological environments on their migration paths.

4. What is the author’s purpose in writing the passage?

B．To analyze the reasons for disappearing of birds’ habitats.

C．To offer some solutions to the problem of birds’ habitats.

D．To tell us a huge percentage of bird species are in danger.

10 . In a county of Britain, a pair of pig farmers has managed to feed one million bees by turning over half of their land to wildflowers. Four years ago, brothers Mark and Paul Hayward decided to fill 81 acres of their farm land with wildflowers. This week, a study found they were feeding one million bees at any time.

“This was our target when we started, to, grow enough flowers to feed a million bees on a single day.” Mark said. “We are acutely aware that bees are under threat from modern farming methods and that East England is one of the worst places where bees are seriously suffering from lack of wildflower diversity,” he continued.

“Every third bite of food you eat can come from bees and we wanted to create an operation on our farm that did not push nature out but rather hugged it-as a central part of our ecology system and our food cycle,” he said.

The farm uses all kinds of seeds which can produce many different wild plants and of course, the bees can get food from different wildflowers.

“We are taking a very small role in helping society restore a balance and this starts with plant diversity to encourage insects, bees, small mammals(哺乳动物), and birds,” said Paul. “At the end of the day, we see ourselves as caretakers of this land. Between us we have six children and we owe it to them to farm sustainability(持续性)and set an example for the generations to come,” added Paul.

According to the Bee Conservation Trust, many types of bees have seen their populations decline by 70%, and two species have become extinct in the last century.

Gill Perkins, CEO of the Bee Conservation Trust said, “Thanks to Mark and Paul, at least here, a million bees can keep living, which is of great significance for ourselves now and future.”
