As long as you have broadband(宽带) service in your home, you can turn on your desktop computer and connect to the Internet. If you have a wireless router(路由器), a device that spreads the broadband connection to other devices, you can set up a Wi-Fi network, which enables your cellphones and tablets go online too. And when you are outdoors where is no Wi-Fi, such as in the park or at the beach, having 3G service allows you to stay connected.
It seems that lots of us have Internet coverage everywhere we go. So why have mobile companies around the world lately been so enthusiastic about a new term, “4G”? First, you need to know that the letter :G” stands for “generation”. Even if you have no idea what 4G is, at least you can figure out that it is a step up from 3G since it’s the latest generation of mobile internet service.
Unlike broadband, mobile Internet uses the same signal towers that provide voice service to your cellphone, which means wherever you can make phone calls with your cellphone you also have an Internet connection.
But mobile connections have their defects: they don’t carry as much information as broadband does, making opening websites and downloading music slower than they are on a Wi-Fi connection. This is why mobile connections have been constantly upgraded since the first generation was launched back in the 1980s.
According to BBC, 4G is five to seven times faster than current 3G network speeds, almost as fast as home broadband. Because of this, 4G is widely suited for services like video downloading, mapping, online shopping and even video conferencing.
To achieve the high speeds, network companies have to spend a lot of money on building new signal towers, which will eventually lead to a higher phone bill if you switch to 4G, and you will also have to get a new phone with 4G capacity. What is paragraph 1 mainly about?
| A．The development of Wi-Fi |
| B．The convenience of using cellphones. |
| C．The influences of the Internet on our life. |
| D．Various ways to get access to the Internet. |
The underlined word “defects” in Paragraph4 probably means_______.
| A．disadvantages | B．functions |
| C．qualities | D．benefits |
What is the weakness of 3G compared with 4G?
| A．Its voice is not as clear as 4G |
| B．It can’t satisfy the users’ basic needs. |
| C．Its network speeds are much slower. |
| D．It has much less popularity than 4G. |
Mobile technology has constantly been improved to_______.
| A．replace broadband | B．increase the network speed. |
| C．download videos | D．connect more cellphones |
What does the author think of 4G service?
| A．Its service is worth the price. |
| B．There is no need to develop it. |
| C．It takes time to be widely used. |
| D．It provides good service at a higher price. |
People turn to magic(魔力)chiefly as a form of insurance--that is, they use it along with actions that actually bring results. For example, hunters may use a hunting charm(咒语). But they also use their hunting skills and knowledge of animals. The charm may give hunters the extra confidence they need to hunt even more successfully than they would without it. If they shoot a lot of game(猎物), they credit the charm for their success. Many events happen naturally without magic. Crops grow without it, and sick people get well without it. But if people use magic to bring a good harvest or to cure a patient, they may believe the magic was responsible.
People also tend to forget magic's failures and to be impressed by its surface successes. They may consider magic successful if it appears to work only 10 per cent of the time. Even when magic fails, people often explain the failure without doubting the power of the magic. They may say that the magician made a mistake in reciting the spell or that another magician cast a more powerful spell against the magician.
Many anthropologists(人类学家) believe that people have faith in magic because they feel a need to believe in it. People may turn to magic to reduce their fear and uncertainty if they feel they have no control over the outcome of a situation. For example, farmers use knowledge and skill when they plant their fields. But they know that weather, insects, or diseases might ruin the crops. So farmers in some societies may also plant a charm or perform a magic rite to ensure a good harvest.From the passage, we can learn that the writer of the passage may be _______.
| A．a hunter | B．a farmer | C．a magician | D．an anthropologist |
Which of the following can best serve as the title of the passage?

In 2001, 11-year-old Kevin Stephan was a bat boy for his younger brother's Little League team in Lancaster, New York. It was an early evening in late July. Kevin was standing on the grass away from the plate, where another youngster was warming up for the next game. Swinging his bat back and forth, giving it all the power an elementary school kid could give. The boy brought the bat back hard and hit Kevin in the chest. His heart stopped.
When Kevin fell to the ground, the mother of one of the players rushed out of the stands to his aid. Penny Brown hadn't planned to be there that day, but at the last minute, her shift(换班)at the hospital had been changed to see her son’s performance. She was given the night off. Penny bent over the senseless boy, his face already starting to turn blue, and giving CPR, breathing into his mouth and giving chest compressions. And he revived in the end.

As computers become all the more popular in China, Chinese people are increasingly relying on computer keyboards to input Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes（笔画）of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.
Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school.And computer dependence is more wide-spread among university students. Almost all their assignments and essays are typed on a computer.
All the students interviewed say they usually use a computer.
It's faster and easier to correct if using a computer. And that's why computers are being applied more and more often to modern education. But when people are taking stock in computers increasingly, problems appear.
"When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I’m familiar with it."
"I'm not in the mood to write when faced with a pen and paper."
Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?
Many educators think differently. Shi Liwei , the headmaster of a famous primary school in the capital said "Chinese characters enjoy both practical and aesthetic(审美的) value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them"
To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory(必修的)and in universities, some professors are asking students to turn in their homework and essays written by hand.Which of the following can best serve as the title of the passage?

Jeremy Wirick, 9, has been back in school for less than two months, but he has already had several asthma(哮喘)attacks. A recent attack happened on October 2, after he pushed himself too hard in gym class. Running, power walking, jogging and push-ups took their toll. When Jeremy got home an hour or two later, he was out of breath. He needed to use a nebulizer, a machine that helps send medicine quickly to the lungs, to get his breathing back to normal.
Asthma attacks like Jeremy increase in September and October. More than six times as many asthma sufferers who are elementary-school age need hospital treatment in the fall as in the summer.
Experts believe many factors can contribute to back-to-school asthma. Kids get together in close spaces, they start passing viruses around. A viral infection can cause an asthma attack. There are also certain fall allergies(过敏症)that can cause attacks. Exercise is another common cause of an attack. Besides, the stress of school can make asthma worse.
Parents can play a big role in helping kids with asthma start the school year right. Dawne Gee’s10-year-old son, Alexander, has had asthma since he was a baby. Before the school year starts, she tells school workers in writing about her son’s asthma.
The Gees live in Kentucky, which has passed laws allowing students to carry their asthma medication(药物治疗)with them at school. Alexander’s mom makes sure he has his inhaler(人工呼吸器)with him when he goes to school and that he keeps it on hand at all times. In Delaware, where Jeremy lives, kids are allowed to carry their inhalers at school.
The American Lung Association says that about 6.2 million American children suffer from asthma. Asthma is the chronic (慢性) illness that causes students to miss the most days of school.

Camping wild is a wonderful way to experience the natural world and ,at its best, it makes little environmental influence. But with increasing numbers of people wanting to escape into the wilderness, it is becoming more and more important to camp unobtrusively（不引人注目地）and leave no mark.
Wild camping is not permitted in many places, particularly in crowded lowland Britain. Wherever you are, find out about organizations responsible for managing wild spaces, and contact them to find out their policy on camping and shelter building. For example, it is fine to camp wild in remote parts of Scotland, but in England you must ask the landowner’s permission, except in national parks.
Camping is about having relaxation, sleeping outdoors, experiencing bad weather, and making do without modern conveniences. A busy, fully-equipped campsite（野营地）seems to go against this, so seek out smaller, more remote places with easy access to open spaces and perhaps beaches. Better still, find a campsite with no road access: walking in makes a real adventure.
Finding the right spot to camp is the first step to guaranteeing a good night’s sleep. Choose a campsite with privacy and minimum influence on others and the environment. Try to use an area where people have obviously camped before rather than creating a new spot. When camping in woodland, avoid standing dead trees, which may fall on a windy night. Avoid animal runs and caves, and possible homes of biting insects. Make sure you have most protection on the windward side. If you make a fire, do so downwind of your shelter. Always consider what influence you might have on the natural world. Avoid damaging plants. A good campsite is found, not made—changing it should be unnecessary.You needn’t ask for permission when camping in.
| A．national parks in England | B．most parts of Scotland |
| C．crowded lowland Britain | D．most parts of England |
The author thinks that a good campsite is one.
A. with easy accessB. used previously
C with modern conveniences D. far away from beachesThe last paragraph mainly deals with
A. protecting animals B. building a campfire
C camping in woodlandD. finding a campsite with privacyThe passage is mainly about
| A．the protection of campsites | B．the importance of wild camping |
| C．the human influence on campsites | D．the dos and don’ts of wild camping |
