(agent) don’t just record everyday goings-on – they capture the relatable emotional connections shared between animals, first-hand. The documentary also won plaudits among critics.

Going to university is a hugely exciting time: you’ll meet new and interesting people, live independently, and no doubt have experiences that will stay with you for the rest of your life. But making such a big move can also be stressful. 1.
It is helpful to know about the town, city or area you re going to live in before you arrive. Work out where the center of town is in relation to your accommodation and the university campus. 2. If not, it’s a good idea to explore the local public transport so you know what to expect head of arriving.
Technology is your friend here. 3. You can join social media groups, chat to other students, find out who is in your halls, and prepare for your course before you’ve even finished packing.
And if you can, keep active. Regular exercise can improve your confidence and help you concentrate, sleep better and feel better. Exercise keeps the brain and other vital organs healthy. 4.
Exercise doesn’t have to be running miles and miles on a treadmill (跑步机). Street dance, rock and roll class, self-defense and playing a competitive sport can keep you in shape.
5. Both of them can have a long lasting effect on physical and mental health. A healthy diet should include different types of fruit and vegetables, wholegrain breads, nuts and seeds, oily fish and plenty of water.
A. Is it within walking distance?
B. Eating and drinking well are also of great importance.
C. In addition, it is a significant benefit to your mental health.
D. Spend time building networks and meeting like-minded people.
E. University should be a time of growth, both mentally and academically.
F. Social media is also a great way for students to stay connected with their parents.
G. Fortunately, there are a few easy steps you can take to prepare yourself for your new life.
The second little pig was unlucky. He built his house from sticks, which was blown away by a wolf. His brother, by contrast, built a wolf-proof house from bricks. The fairy tale could have been written by an agent for the construction industry, strongly favoring brick, concrete and steel. However, in the real world it would help reduce pollution and slow global warming if more builders copied the wood-loving second pig.
No other building material has environmental credentials (认证信息) as exciting and overlooked as wood. The energy required to produce a laminated wooden beam (层压木梁) is one-sixth of that required for a steel one of comparable strength. As trees take carbon out of the atmosphere when growing, wooden buildings contribute to negative emissions by storing the stuff. And for refitting older buildings to be more energy efficient, wood is a good insulator (绝缘体). A softwood window frame provides nearly 400 times as much insulation as a plain steel one of the same thickness and over a thousand times as much as an aluminium (铝) equivalent.
But such bigger stories are still uncommon. Governments can help push the industry to use more wood, particularly in the public sector — the construction industry’s biggest client. That would help wood-building specialists achieve greater scale and lower costs. Zero-carbon building regulations should be altered to take account of the emissions that are presented in materials.
Construction codes could be regulated to make building with wood easier. Here the direction of travel is wrong. Britain, for instance, is banning the use of timber on the outside of tall buildings after 72 people died in a tower fire in London in 2017. That is a nonsense. Grenfell Tower was covered in aluminium and plastic, not wood. Modern cross-laminated timber (交叉层叠木板) panels perform better in fire tests than steel ones do.
Carpentry alone will not bring the environmental cost of the world’s buildings into line. But using wood can do much more than is appreciated. The second little pig was not wrong, just before his time.

Why elephants rarely get cancer is a mystery that has confused scientists for decades. A study led by researchers at Huntsman Cancer Institute (HCI), at the University of Utah and Arizona State University may have found the answer.
According to the results, elephants have 38 additional modified copies of a gene that encodes p53, a definite tumor suppressor, as compared to humans, who have only two. Further, elephants may have a more powerful mechanism for killing damaged cells that are at risk for becoming cancerous. In isolated elephant cells, this activity is doubled compared to healthy human cells, and five times that of cells from patients with Li-Fraumeni Syndrome, who have only one working copy of p53 and more than a 90 percent lifetime cancer risk in children and adults. The results suggest extra p53 could explain elephants’ increased resistance to cancer.
“Nature has already figured out how to prevent cancer. It’s up to us to learn how different animals overcome the problem so we can adapt those strategies to prevent cancer in people,” says co-senior author Joshua Schiffman, M.D., pediatric oncologist (儿科肿瘤医生) at Huntsman Cancer Institute, University of Utah School of Medicine.
But Prof Mel Greaves, from the Institute of Cancer Research in London, says we should focus on why humans have such high levels of cancer. He pointed to the rise of unhealthy, cancer-causing behaviors, such as obesity and sunbathing. “You’ve never seen an elephant smoke!” he added.
According to Schiffman, elephants have long been considered a walking problem. Because they have 100 times as many cells as people, they should be 100 times more likely to have a cell slip into a cancerous state and cause the disease over their long life span of 50 to 70 years. And yet analysis of a large database of elephant deaths estimates a cancer death rate of less than 5 percent compared to 11 to 25 percent in people.
1.Why are elephants less likely to get cancer than humans?
A.Elephants are bigger than humans.
B.Elephants have more p53 genes and mechanism killing damaged cells.
C.Elephants are not as clever as humans in walking.
D.Elephants eat more than humans.
2.Which of the following can be the equivalent of the underlined word “suppressor”?
A.multiplier B.complex C.restrainer D.coordinator
3.What’s Prof Mel Greaves’ attitude towards the discovery?
A.Doubtful. B.Neutral. C.Critical. D.Favorable.
4.What can we infer from the last paragraph?
A.Elephants have longer life than people.
B.There is no chance that elephants die from cancer.
C.The rate of elephants dying from cancer is increasing.
D.It was thought theoretically that elephants could get cancer more easily.
When I was a child growing up in Ohio, the butterflies would sometimes pass through on their way to Mexico. And it was awesome to see football fields full of them — and I wanted to revisit that on a larger scale. I knew I had to go to see the migration in Mexico.
But I was on a budget. I didn’t want to rent a car in Mexico or take a bus to Valle de Bravo, the starting point for most butterfly adventures, so I called the guys at the Muddy Boot, travel experts in Mexico who can make almost anything happen at a reasonable rate.
And so, on January 2, I found myself in the Muddy Boot van (货车), being driven two hours from Mexico City to Valle de Bravo, a lovely town on a volcanic lake which is a central point for the butterfly journeys. I booked a two-night stay at the Hotel Rodavento, an all eco-friendly hotel with individual wooden houses spread throughout the forest and around a lake.
The first sanctuary (保护区) I visited was Piedra Herrada, a popular destination, as it is only 40 minutes away from Valle de Bravo. The climb up is tiring. It is advisable to hire a horse. But the horse cannot take you all the way, and there is some hiking in thin air, so you must be patient, drink a lot of water, and be in reasonably good shape.
The walk is more than worth it, though. As I struggled to catch my breath, I looked up and lost my breath again. At first glance, the trees had turned into different shapes, but on closer inspection, every inch of them was covered with butterflies.
A few flew through the air (Most of them were not warm enough). As the sun rose, they began to come alive. Soon the air was filled with flying butterflies, transforming the forest into something magical and straight out of a fairy tale.

A.She couldn’t afford to rent a car.

D.She hoped to reach the destination earlier.
2.What can we learn about Piedra Herrada?
A.It is at a high altitude. B.It is far from Valle de Bravo.
C.It is full of wild animals. D.It is only accessible by riding a horse.
3.What made the author’s hiking worthwhile?
A.Becoming healthier. B.Breathing in fresh air.
C.Finding trees of different shapes. D.Seeing the butterfly migration.
4.What type of writing is the text?
A.A news report. B.A scientific paper. C.A travel diary. D.A commercial ad.
