It’s easy when travelling to pull in to fast food restaurants for snacks.
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. |

4 . 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.
1. How many wild pandas are there in China?A.About 260. | B.About 635. |
C.About 2,635. | D.About 2,000. |
A.China needs more help from the World Wildlife Fund. |

C.Bamboo is sensitive to the changes of temperature. |
D.China is making great efforts to protect the pandas. |
A.The Qinling Mountains can provide enough bamboo for the pandas. |
B.Pandas in the Qinling Mountains are only threatened by the loss of food. |
C.Lots of the bamboo in the Qinling Mountains will probably disappear. |

5 . 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.

9 . 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.”

10 . Priscilla Ouchida’s “energy efficient” house turned out to be a horrible dream. When she and her engineer husband married a few years ago, they built a $100,000 three-bedroom home in California. Tightly sealed to prevent air leaks, the house was equipped with small double-paned windows and several other energy-saving features. Problems began as soon as the couple moved in, however. Priscilla’s eyes burned. Her throat was constantly dry. She suffered from headaches and could hardly sleep. It was as though she had suddenly developed a strange illness.
Experts finally traced the cause of her illness. The level of formaldehyde gas in her kitchen was twice the maximum allowed by federal standards for chemical workers. The source of the gas? Her new kitchen cabinets and wall-to-wall carpeting.
The Ouchidas are victims of indoor air pollution, which is not given sufficient attention partly because of the nation’s drive to save energy. The problem itself isn’t new. “The indoor environment was dirty long before energy conservation came along,” says Moschandreas, a pollution scientist at Geomet Technologies in Maryland. “Energy conservation has tended to accentuate the situation in some cases.”
The problem appears to be more troublesome in newly constructed homes rather than old ones. Back in the days when energy was cheap, home builders didn’t worry much about unsealed cracks. Because of such leaks, the air in an average home was replaced by fresh outdoor air about once an hour. As a result, the pollutants generated in most households seldom built up to dangerous levels.
1. It can be learned from the passage that the Ouchidas’ house ________.A.is well worth the money spent on its construction |
B.is almost faultless from the point of energy conservation |
C.failed to meet energy conservation standards |
D.was designed and constructed in a scientific way |
