1 . In habitats across the planet, animals periodically drop everything to walk, fly or swim to a new place. Some animals such as whales and geese learn migration paths by following their parents. Others, including small songbirds, gain the distance and direction of their migration within their genetic code. And some animals use a combination of genetics and culture to guide their migration.

Another group of migrators does not quite fit either model, and researchers have only recently started to figure out how they find their way. The Cory’s shearwater is an oceangoing seabird that migrates over the Atlantic every year. The young do not migrate with their parents, so culture cannot explain their journeys. And the exact paths vary wildly from individual to individual, making genetics equally unlikely.

Cory’s shearwaters are long-lived, rarely producing young successfully before age nine. This leaves an opening for learning and practice to develop their migration patterns. Researchers call this the “exploration-refinement”, and until now it has been hypothetical (假设的) because of difficulties in tracking migratory animals’ movements.

But a team of researchers has done that by attaching small geolocators to more than 150 of the birds aged four to nine. They found that younger birds traveled longer distances, for longer periods, and had more diverse paths than older birds. “We finally have evidence of the ‘exploration-refinement’ for migratory birds,” says Letizia Campioni, who led the study. Younger Cory’s shearwaters are able to fly just as fast as the adults——but they do not, suggesting that the young do more exploring, which gradually fades as they mature and settle into a preferred course.

“Although it may seem less efficient than other strategies, exploration refinement could be beneficial to birds and other organisms in a rapidly changing world due to unpredictable man-made changes,” says Barbara Frei. “It might be safer to repeat a behavior that was recently successful than to rely on patterns that were perfected long ago but might no longer be safe.”

2 . Friends always ask why I, a middle-aged woman with no athletic (运动) talent (天赋), travel to perilous places — the jungles (丛林) of Thailand or Borneo, for example, where the water is often unsafe and the food risky; places with infectious diseases, poisonous snakes and the wildest animals.

I never know how to answer. Nine years ago I suffered a stroke (中风). To prevent another stroke, my doctors told me, I’d have to take dangerously high levels of blood thinner (血液稀释剂) for the rest of my life and any travel would be risky (冒险的).

I had to think about what was important to me: family, of course, and friends. But then what? No matter how many times I thought about it, I could not be happy without travel. Then I had to decide how I might manage the risk.

The first real test of my travel courage came nine months after my stroke when I joined my husband, Jack, on a business trip to China. After we’d toured the remains of a Tang dynasty temple on a high mountain, Jack wanted to ride down on a toboggan (长雪橇).

Before the stroke it would’ve seemed like fun. But now? I hesitated. My mental klaxon (高音喇叭) screamed warnings about the consequences of a cut, a fall, and a crash. Then, gaining confidence from who knew where, I lowered myself carefully into the toboggan, which marked my adventure (冒险) travel come back.

In the years since then, I’ve traveled about twenty-five percent of the time. Through it all, my lucks held out — no deadly falls, no car accidents or serious infections. For me, adventure travel is a risk worth taking. Travel broadens my world and keeps me connected to nature. What’s more, saying “yes” to travel keeps me connected to myself.

3 . Foreign visitors to the UK might be disappointed when they learn that not everyone there speaks like Harry Potter and his friends. Usually, there’s an assumption by many non-Brits that everyone in Britain speaks with what’s known as a Received Pronunciation (RP，标准发音) accent, also called “the Queen’s English”. However, while many people do talk this way, most Britons speak in their own regional accents (口音).

Scouse, Glaswegian and Black Country — from Liverpool, Glasgow and the West Midlands — are just three of the countless non-RP accents that British people speak with. There are even differences in accents between towns or cities just 30 kilometers apart. What is even more disappointing is that not speaking in a RP accent may mean a British person is judged and even treated differently in their everyday life.

In a 2015 study by The University of South Wales, videos of people reading a passage in three different UK accents were shown to a second group of people. The group then rated how intelligent they thought the readers sounded. The lowestrated accent was Brummie, native to people from Birmingham, a city whose accent is considered working class.

However, there is no need to be disappointed though you are not speaking in a RP accent. In fact, doing the opposite may even give you strength.

Kong Seongjae, 25, is an Internet celebrity from Seoul. After studying in the UK, he picked up several regional accents. He’s now famous for his online videos, where he shows off the various accents he’s learned. “British people usually get really excited when I use some of their local dialect words, and they become much friendlier. I think it makes a bit of bond between local people and foreigners to speak in their local accent,” he said.

So if you’re working on perfecting your British accent, try to speak like someone from Liverpool, Glasgow or Birmingham. You may not sound like Harry Potter, but you are likely to make more friends.

1. What can we infer from Paragraph 1?

A．Non-Brits usually hold that all Britons speak in a RP accent.

3. What does the underlined phrase “doing the opposite” in Paragraph 4 refer to?

A．Speaking in a RP accent.	B．Speaking in regional accents.
C．Speaking the Brummie accent.	D．Speaking like Harry Potter.

4. What is the passage mainly about?

A．A study about the most intelligent accent in Britain.

B．A comparison between different British accents.

4 . What a day! I started my new school this morning and had the best time. I made lots of new friends and really liked my teachers. I was nervous the night before, but I had no reason to be. Everyone was so friendly and polite. They made me feel at ease. It was like I’d been at the school for a hundred years!

The day started very early at 7:00 am. I had my breakfast downstairs with my mom. She could tell that I was very nervous. Mom kept asking me what was wrong. She told me I had nothing to worry about and that everyone was going to love me. If they didn’t love me, mom said to have a good talk with them. I couldn’t stop laughing.

My mom dropped me off at the school gate about five minutes before the bell rang. A little blonde girl got dropped off at the same time and started waving (招手) at me. She ran over and told me her name was Abigail. She was very nice and we became close straight away. We spent all morning together and began to talk to another girl called Stacey. The three of us sat together in class all day and we even made our way home together! It went so quickly. Our teacher told us that tomorrow we would really start learning and developing new skills.

I cannot wait until tomorrow and feel as though I am really going to enjoy my time at my new school. I only hope that my new friends feel the same way, too.

5 . Vehicles on our roads are now mostly petrol and diesel (柴油) cars, but their days cannot continue for much longer. A recent university study found that current electric cars could be used for 87 percent of daily car journeys in the US. That figure could rise to 98 percent by 2020.

One hurdle to the widespread adoption of electric cars has been “range anxiety” — drivers concerns about running out of electricity on a journey. While petrol stations are conveniently located across national road systems, the necessary network of electric charging stations is still being developed. That said, charging points are becoming increasingly common throughout the USA.

Attitudes towards electric vehicles have changed greatly over the last few years. Not that long ago, electric cars were met with distrust, and their high prices drove customers away. Thanks to improvements in battery capacity, recharging times, performance and price, the current generation of electric cars are starting to persuade picky consumers. Plug-in cars will soon give internal combustion engine (内燃机) models a run for their money.

As well as development on the road, electric vehicles are taking to the seas and skies. Electric boats are among the oldest methods of electric travel, having enjoyed several decades of popularity from the late 19th to the early 20th century before petrol-powered outboard motors took over. Now, the global drive for renewable energy sources is bringing electric boats back. Steps towards electric air travel are also being made, with Airbus and NASA among the organizations developing and testing battery-powered planes. The experiments could soon make commercial electric flight a reality.

Electric vehicles do not produce any emissions (排放). If the US could replace 87 percent of its cars with electric vehicles, it would reduce the national demand for petrol by 61 percent. However, because of the production processes and the generation of electricity required to charge these vehicles, they cannot claim (声称) to be completely emission-free. That said, as many countries continue to increase their use of renewable energy sources, electric vehicles will become even cleaner.

8 . There are many weird sports that are present around the world. From each region of the world, along with the very popular common sports, there are also those really popular but very weird kinds of sports.

The Ultimate Test Between Man and Horses

This is indeed a very strange kind of sport that tests your stamina (耐力). You will learn how to be agile (灵活的) while competing against a horse. This game originated in the Welsh town of Llanwrtyd Wells. This sport really has to do with strength. You will require great agility and strength in order to take part in this. Marathon human contestants are put to compete against those mounted people. This is how the marathon testing takes place.

Love Locked Races

This is a sports event that was first introduced in Finland. This is all about a male competitor racing with a female in a certain way. There would be many obstructions and blocks on the way which would definitely bring you challenges. The person to win would have to finish the race without losing his female partner in the course of overcoming the obstacles even for once. This race takes place really fast and the obstacles are set that way.

The Toe Sport

This is yet another weird sport that welcomes you to use your toes. This is quite the same kind of sport that you used to play as a child which involved toe wrestling. This has now been turned into a major sport that even has a World Toe Wrestling Competition. It first originated in a pub of Derbyshire.

The locals took this sport with great enjoyment and then made this so popular that it soon had its own championship. The individuals who participate have only got to use their feet and then this is tougher than it may sound.

The Mud Pit Belly Flop

This is a kind of game where even the spectators (观众) get splashed with mud but in fact that is quite the fun. The very annual Summer Redneck Games in East Dublin bring about this game and bring about some of the greatest hubcap-discus throws with it. This is also a great sport to show the strength and dexterity of your feet.

9 . Most people agree that eating healthy food is important. But sometimes making good food choices can be difficult. Now there are apps that can help people learn about the food they eat to improve their health and their dining out experience.

Open Table app

Open Table app helps people choose restaurants when they want to go out to eat. It is a free service that shows users restaurant available based on where and when they want to dine. It gives users points when they make reservations, which can add up to discounts (折扣) on restaurant visits.

Max McCalman’s Cheese &Wine Pairing app

Wine and cheese can be a great combination. But which wines go best with which cheeses? Max McCalman’s Cheese & Wine Pairing app can help. It provides information about hundreds of different cheeses and suggests wines to pair with each. Max McCalman’s Cheese & Wine Pairing app is free.

Happy Cow app

Vegetarians do not eat animal meat. Vegans do not eat any animal products. The Happy Cow app is made for both groups. Users can search for vegetarian-vegan restaurants and stores around the world.

Local Eats app

Restaurant chains, like McDonalds, can be found almost anywhere a person might travel. But sometimes travelers want to eat like locals. The Local Eats app is designed for that. It can help you find local restaurants in major cities in the US and in other countries. It costs about a dollar.

Where Chefs Eat app

“Where Chefs Eat” is a 975-page book. Most people would not want to carry that around. But there is a much lighter app version of the same name for just $15. Six hundred chefs provide information on 3,000 restaurants around the world on the Where Chefs Eat app.

10 . Losing your ability to think and remember is pretty frightening. We know the risk of dementia (痴呆症) increases with age. But if you have memory slips, you probably needn’t worry. There are pretty clear differences between signs of dementia and age-­related memory loss.

After age 50, it’s quite common to have trouble remembering the names of people, places and things quickly, says Dr. Kirk Daffner of Brigham and Women’s Hospital in Boston.

The brain ages just like the rest of the body. Certain parts become smaller, especially areas in the brain that are important to learning, memory and planning. Changes in brain cells can affect communication between different regions of the brain. And blood flow can be reduced as blood vessels narrow.

Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about. But if you forget the plot of the movie or don’t remember even seeing it, that’s far more concerning, Daffner says.

When you forget entire experiences, he says, that’s “a red flag that something more serious may be involved”. Forgetting how to operate a familiar object like a microwave oven, or forgetting how to drive to the house of a friend you’ve visited many times before can also be signs of something going wrong.

But even then, Daffner says, people shouldn’t panic. There are many things that can cause confusion and memory loss, including health problems like temporary stoppage of breathing during sleep, high blood pressure, or depression, as well as medications (药物) like antidepressants.

You don’t have to figure this out on your own. Daffner suggests going to your doctor to check on medications, health problems and other issues that could be affecting memory. And the best defense against memory loss is to try to prevent it by building up your brain’s cognitive (认知的) reserve, Daffner says.

“Read books, go to movies, take on new hobbies or activities that force one to think in novel ways.” he says. In other words, keep your brain busy and working. And also get physically active, because exercise is a widely known to boost the brain.

1. Which memory-related symptom should people take seriously?

A．Totally forgetting how to do one’s daily routines.

B．Inability to recall details of one’s life experiences.

C．Failure to remember the names of movies or actors.

D．Occasionally confusing the addresses of one’s friends.

2. What should people do when signs of serious memory loss show up?

A．Check the brain’s cognitive reserve.

B．Stop medications affecting memory.

C．Turn to a professional for assistance.

D．Exercise to improve their well­being.

3. What is Dr. Daffner’s advice for fight against memory loss?

A．Having regular physical and mental checkups.

B．Taking medicine that helps boost one’s brain.

C．Engaging in known memory repair activities.

D．Staying active both physically and mentally.

4. Which of the following is closest in meaning to the underlined word “boost” in the last paragraph?

A．Reduce.

B．Benefit.

C．Increase.

D．Depress.
