    In the most southern part of our planet, there's a place that's covered with snow and ice all year round. But it has the clearest and cleanest air. Amazingly, in this place, the sun sometimes hangs even in the midnight sky. This place is Antarctica (南极洲): the coldest, windiest and harshest (恶劣的) place on the Earth.
    As the world's least-known place, Antarctica is of great interest to scientists around the world. In 1983, China joined the Antarctic Treaty (《南极条约》). The treaty made Antarctica a peaceful place for member countries to do scientific research. During 30 years, China has sent many scientists to Antarctica. They mostly look at the resources under the icy land and do research about climate change and marine (海洋的) biology.
    Antarctica is a place with fantastic views. However, life there is very hard. Food is one of the biggest problems. Frozen (速冻) food which can be heated easily is people's daily food. Fresh vegetables are hard to grow in the cold weather. Therefore, scientists often eat dried or canned vegetables.
    Sleep is also troublesome. In Antarctica, summer lasts from November to March. During this period, Antarctica points to the sun and receives sunlight 24 hours a day. In order to get some sleep, scientists cover the windows with black plastic cloth to create “night”.
Working in Antarctica is dangerous, especially when meeting gale-force (七级以上的) winds. Sometimes the wind is even stronger than a typhoon. It can easily blow people away. So there are ropes that connect buildings of some research stations. People can hold these ropes to keep their balance in forceful winds.
    What's more, communicating with others is difficult. Without cables and Internet in some research stations, two-way radios are the only tools to communicate. If people want to say hello to friends and relatives, they can use satellite phones.
    Although it is challenging to work in Antarctica, scientists' passion to learn about this mysterious land will never end. It is hopeful that one day they will step every corner of this icy land.

(1)、From Paragraph 1, we learn that the Antarctica ______.

A、is covered with snow and ice B、rains heavily from time to time C、has little wind most of the time D、has sunshine during every night
(2)、Scientists from China go to Antarctica to _____.

A、find out ways to control water pollution B、research climate change and marine biology C、grow plants and vegetables in special condition D、stop the hunters from killing the marine biology
(3)、In order to sleep well in Antarctica, the scientists have to _____.

A、wear more clothes to keep warm B、cover the windows with black cloth C、connect research stations with ropes D、eat more fried and canned vegetables
(4)、We can replace (替换) the underlined word passion in the last paragraph with       .

A、strong love B、full preparation C、pleasant introduction D、amazing imagination
(5)、The passage is mainly about       .

A、view of the Antarctica B、exploring the Antarctica C、how to survive in the Antarctica D、climate changes of the Antarctica

Buying clothes in a busy shop can be a bad thing. But shopping online can be a bit hit-and-miss. Sometimes you can't find what you like. So shopping online is not an easy thing. This has led to a number of companies' owners to come up with a new idea—interactive mirrors (互动试衣镜) in shops that let you try on different clothes with different colors and patterns (样式) without putting on or taking off by yourself.

Now the scientists have made the latest interactive mirrors in the USA. The interactive mirror uses a new kind of technique (技术) to show how clothes will fit. It was founded by a person named Salvador Nissi Vilcovsky who was from California. There is a little device (装置) like a computer behind the mirror. First, we should store kinds of clothes including colors and patterns in the mirror. Then, when the customers stand in front of the mirror, the shop assistant only uses hand gestures. Through the gestures, there will be different kinds of pictures in the mirror. The pictures show the right customer in different clothes without any changing. The shop assistant can change different colors, patterns and sizes, and the smart mirror will remember top two best choices, so the customer can compare and contrast. It also lets people see clothes from different angles (角度) without straining (用力拉) their neck or using a wall of mirrors. In 2014, the technology was introduced into Neiman Marcus stores in San Francisco, and later, Texas. It was widely welcomed by the shop owners and the customers. Maybe, we can see one of these interactive mirrors in a shop in China in the near future.

Last year, some locals in Shenzhen suggested cancelling the city's ban(禁令)on fireworks. However, the local government said the city was not ready to allow fireworks.

The government said it was mostly because of the growing power of modern fireworks. Nowadays, in order to improve light effects, firework makers would put more gunpowder in their products. Sometimes, some of these fireworks may go off like small bombs(炸弹), causing damage and hurting people.

During the last forty years, Shenzhen has developed into a huge city, and most of its population lives in urban(城市的)areas. Now, nearly 20 million people live in an area of just 2,000 square kilometers. In addition, there are at least 1,500 urban villages and 1,000 high-rise buildings.

Other major cities, like Beijing and Shanghai, allow people to set off fireworks at special areas during the Spring Festival this year. Shenzhen, however, has difficulty doing that because there is hardly enough public space, especially in urban villages. There, you will see plenty of "handshake" buildings. These buildings are usually several inches—the distance of a few handshakes—away from each other. If people set off fireworks through their windows, it may cause fire. Therefore, the locals and the government are working together to keep them clean and well-organized. As a result, people can enjoy a happy and safe new year.

Shenzhen made a rule in 2013 to ban fireworks. Once the rule was made, it caught a lot of attention from the public. After much explanation, people started to take it. No major fire has been caused by fireworks since then.

①Why do we do the things we do? What drives our behavior? Researchers have suggested different ways of thinking about motivation (动机), including looking at whether motivation comes from outside or inside a person.

②Extrinsic (外来的) motivation is when you decide to do something because you want to get a reward or avoid punishment. Intrinsic (内在的) motivation is when you do something because you find it enjoyable. The behavior itself is its own reward.

③There are many advantages of intrinsic motivation. Firstly, it's lasting. It makes people willing to face challenges and work hard to achieve their goals. Besides, people with intrinsic motivation have a greater sense of satisfaction.

④Most people think intrinsic motivation is best, but it is not always possible in every situation. Sometimes a person has an unpleasant task and he may not have internal (内部的) wish to complete it. That's when we need extrinsic motivation. But studies have shown that offering too-many external (外部的) rewards can reduce (减少) intrinsic motivation. For example, in a study, children were playing with the toys they liked. When they were externally rewarded for their behavior, they became less interested in the toys.

⑤Both extrinsic and intrinsic motivation play a key role in learning. Experts have argued that traditional education pays too much attention to external rewards, such as grades. This undermines the intrinsic motivation that students might already have. However, others have suggested that extrinsic motivation can help students feel more knowledgeable in class. It helps to build up their intrinsic motivation.

⑥Understanding how each type of motivation works and when it is likely to be useful can help people complete tasks and improve their learning.

①In most places in the world today, it is easy to find healthy food. With supermarkets, buying healthy food like fresh fruits, vegetables, fish, and meat is easy and convenient(便利的). However, it is also easy to find unhealthy food today. Supermarkets and other stores sell good food, but they also sell frozen foods and junk food like chips, candy, and cookies. A lot of food today has chemicals(化学药品). Research has shown that many of these chemicals are bad for our health. So did people in the past eat healthier than we do today?

②A century ago, people didn't eat junk food or frozen food. Instead, they ate natural foods without chemicals. On the other hand, their natural foods were not always as good as food today. In the past, meat often came from sick animals. It's not healthy to eat meat from a sick animal. In most places today, laws make sure that food is safe.

③In most countries today, we can buy a variety(各种)of foods. We can buy oranges in the winter and apples in the summer. Healthy fruits and vegetables are available(可获得的)at any time of year. These foods come from all over the world. In the past, this kind of variety was not possible. People could eat certain foods only in certain seasons.

④We also eat much more meat, sugar, fattening foods, and chemicals today than people did a century ago. Studies show that these things can cause(引起)heart disease(疾病)and a variety of other health problems. However, people live much longer now. Today, the average(平均)person lives for 70 to 80 years. However,100 years ago, the average person lived for only about 50 years. People live longer because we have better medicine now. But people also have longer lives because healthy food is usually available.

⑤So ____? Yes and no. People in the past did eat more natural food than we do now. But, in some ways, we also eat better today. We can eat healthier today than people did in the past. We just have to choose to eat good foods.

 阅读下列短文, 从每题所给的四个选项(A、B、C和D)中选出最佳选项。

 Have you noticed that people speak differently to babies compared to adults? Caregivers, especially mothers, change their speech when talking to young children. How? Their speech includes higher pitch (音高) and a wider pitch range (范围). They use shorter sentences and repeat words more often. You can think of it as baby talk. Researchers have recently discovered that dolphins also use baby talk with their babies.

The research team recorded sounds of 19 mother dolphins living in the Sarasota Bay area. The sounds of the same female dolphins were compared when they were with and without their babies. Chart 1 shows the sound of a female dolphin without her baby. The researchers found that when dolphins were with their babies, dolphin mothers had a wider range of frequencies (频率) of the sound-the maximum (最高 ) frequencies were higher and the lowest frequencies were lower.

The findings mirror the way that humans change the speech when speaking to babies. Dolphin baby talk may have a similar purpose to human"baby talk" it may help babies learn how to phonate. We humans don't only use baby talk with little babies, but with the children who are still learning to speak. As a result, our children are able to talk. That's exactly what happens to dolphins. The changes in speech don't just happen when dolphin mothers stay with very young babies, but also between mothers and babies that are closer to"toddler (学步的幼儿)" age. Another possible reason for using specific pitch is to catch the children's attention. It's really important for a young dolphin to know"Oh, Mom is talking to me now."

 The research about baby talk in dolphins reminds us how important it is in humans. Whenever we speak with a young child, how we say things could be as important as what we say.
