1 . When you think of a map, is north on the top or the bottom? Usually, maps are designed with north on top, though when we think about it, there is no logical reason for this bias (偏见). After all, there is no up or down in space. So what is wrong with south, east or west being on the top of the map? The answer is: nothing at all. In fact, north-up maps only became the norm in the last few hundred years.

Ancient Egyptian maps had south at the top because the Nile River flows downhill from mountains in the south to the Mediterranean Sea in the north. Mecca was to the south of most early Muslim civilizations, and south-up maps were designed so that viewers would look up to see Mecca. Medieval Christian maps had east at the top, as they believed the Garden of Eden was in the east. The only early maps that had north at the top were those of early China because the emperor lived in the north.

North seems to have settled at the top of maps during the 16th century, largely thanks to a Flemish mapmaker, Mercator. Mercator was a great admirer of an early Greek mapmaker, who, for reasons now unknown, put north at the top of maps, so Mercator did, too. When Mercator’s world map became the standard map to navigate the oceans, north up became standard as well.

What is the implication of this north-view of the world? Psychologically, people tend to think of up as good and down as bad. Just think of words and phrases like “upmarket”, “upbeat” and “moving up in the world”, and how they contrast with their opposites. Because north is so consistently put at the top of maps, people now think of north as good, too.

Several attempts have been made in recent years by introducing south-up maps to the market. These maps not only give us a chance to see the world differently, but also give everyone the chance to see themselves on top.

2 . J. K. Rowling frequently shows there is magic every day. Her Harry Potter series has helped people through times of stress and depression and she is always there to deliver wise words of encouragement.

She is one celebrity who is very active on Twitter. So when a single dad named Matt Burke sent her a message thanking her for the series, she noticed. Her series had helped strengthen his relationship with his 9­year­old daughter Bailey.

He included a link to his article titled Being a Broke Parent. He explained how he hadn’t found a level of financial stability that allowed him to pay bills on time and take his daughter on more activities and events. The family also doesn’t have the Internet or TV, which means there’s no “digital babysitter” and he has to rely on his own creative ways to bond with his daughter. Since he received the series, the main thing that has occupied them these days is reading books together.

Burke admits that he thought he was “too cool” for the books when they first came out and he was in his twenties, but he’s loving reading them now. “We switch off chapter by chapter reading them out loud，“Burke explains.” This not only allows her to get more used to reading aloud in front of someone, but it gets me directly involved in something she loves, and it gives me the chance to be very dramatic when I read my chapters and bring myself into the characters in the book, which has proven to be a ton of fun.”

After hearing Burke’s story, Rowling said how honored she was when Harry Potter was a part of his family’s life and offered Burke more books. Besides, people are also offering to send Burke more books as gifts. For Burke, this experience, far more than gifts, will be what he treasures.

1. Why did Burke thank J. K. Rowling according to the text?

A．She guided him how to write a good story.

B．She encouraged him when he was in trouble.

C．He has chosen a better way of reading the series.	D．He hopes to play a role in the drama in the future.

3. Which word can best describe Burke’s experience according to the text?

A．Useless.

B．Normal.

C．Valuable.

D．Boring.

4. What is the main idea of this text?

C．J. K. Rowling has a deep influence on others’ growth.

D．Burke comes to know J. K. Rowling through her series.

3 . Are you happy with your appearance?     1    

“Almost all the girls with single-fold eyelids (单眼皮) in our class have had double eyelid operations,” Zeng, a Senior 2 student from Chengdu, told Xinhua. Zeng had the same surgery done this summer.     2    

From popular photo-editing apps to plastic surgery (整形手术), it seems that large eyes, pale skin and a skinny body are the only standard for beauty these days. But can following this standard really make us feel good about ourselves?

    3     . According to Huxiu News, over six in ten girls choose not to take part in certain daily activities, such as attending school, because they feel bad about their looks. As much as 31 percent of teenagers avoid speaking up in class because they worry that others will notice their looks.

“Many teenagers are upset about their appearance because they believe in unrealistic standards of beauty,” experts say.       4     Seeing all these things can make anyone believe that they’re too dark, too fat, too short, or too tall.

However, trying to live up to strict standards can make us feel anxious. What troubles us is not just our “imperfect” looks, but the fact that we criticize ourselves too much.

    5     Plus-size models are being featured in some fashion shows. All of us should be just as confident as they are.

A．Beauty comes in all shapes and sizes.

B．Body image anxiety is common among teenagers.

C．Guys care just as much as girls do about their body image.

D．Some teenagers might feel negative about their appearance.

E．It’s common for teenagers to feel confident about their appearance.

F．She and many of her classmates believe bigger eyes look more beautiful.

G．Perfect faces and bodies are everywhere in advertising, TV shows and social media.

4 . Smartwatches and fitness trackers (健身追踪器) have gained popularity recently. These tools can record your daily steps, heart rates, etc.     1    . If yes, it might be a sign that you’re addicted to your fitness tracker.

    2    . If you keep setting unrealistic daily goals that involve working out for too long, and if you begin to ignore friends and responsibilities to make time for your workout, then you’re most probably addicted to your fitness tracker.

It’s a struggle to overcome the addiction to fitness trackers.     3    . For example, the number in your smart watch showing how far you’ve come can give you a sense of achievement.

Of course, failing to meet your daily goal can be discouraging. You might focus on your shortcoming rather than your progress. Another problem is that you might find yourself paying too much attention to the step number rather than how your body feels.     4    .

Therefore, if you’re spending too much time looking at your smartwatch, limit your daily step count to a comfortable level.     5    . For example, concentrating on your hobbies or socializing with friends can be a great way to keep your mind on other things.

A．How can you tell whether you’re addicted to your fitness tracker?

B．Actually this addiction to step count can be risky, mentally and physically.

C．Don’t overuse your smartwatch.

D．However, do you find yourself checking your steps and heart rates too often?

E．After all, reaching a daily step count can be so appealing.

F．Besides, you can find other things to do that don’t involve checking your fitness tracker.

G．It doesn’t covey what you’re really feeling.

7 . Is It Worth Buying Organic Food?

Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious (有营养的) and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.

The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. “We did not find strong evidence that organic food is more nutritious or healthier,” says Dr. Crystal Smith-Spangler from Stanford. “So consumers shouldn’t assume that one type of food has a lower risk or is safer.”

For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.

While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.

Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The U.S. Department of Agriculture (USDA) states that “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.

8 . A five-­year-­old dog named Kelsey has been praised as a hero for helping to save the life of her owner who slipped in the snow and broke his neck.

The man, Bob, was alone when he left his farmhouse on New Year’s Eve to collect firewood.Expecting a journey of only several meters, Bob was wearing just long johns (衬裤), a shirt and slippers when he went outside, although the temperature was around －4℃.

After the accident, he was unable to move in the snow. Fortunately, Kelsey came to his assistance.

“I was shouting for help, but my nearest neighbor is about 400 meters away, and it was 10:30 p. m.,” Bob explained. “By the next morning, my voice was gone and I couldn’t yell for help, but Kelsey didn’t stop barking.”

Kelsey’s companion kept him warm by lying on top of him. She licked his face and hands to keep him awake. “Kelsey kept barking but never left my side,” Bob recalled. “I knew I couldn’t give up and that it was my choice to stay alive.”

Bob spent 20 hours in the freezing cold. When he finally lost consciousness, his dog kept barking. Finally, hearing the barking, Bob’s neighbor discovered him at 6:30 p. m. on New Year’s Day and called the emergency services at once. When Bob arrived in hospital, his body temperature was below 21℃. However, doctors were surprised to find that he didn’t have any frostbite (冻疮). They believed it was because of Kelsey’s determination to keep him warm. Dr. Chaim Colen, the doctor who treated Bob, said, “His dog really saved him.He was very fortunate.”

Bob said he was very grateful to both Dr. Colen and his Kelsey. “They saved my life. They are truly heroes!”

9 . 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.

4. Which is the best title for this passage?

A．Driving into a Cleaner Future	B．History of Electric Cars
C．Problems with Petrol and Diesel Cars	D．Best Means of Transportation

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.

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.
