1 . If you’ve ever had trouble getting your teen up in the morning or you’ve seen your teen fall asleep during the school day, you’re not alone. Many teens have difficulty in waking up early for school, and that’s because they sleep late at night.

The American Academy of Pediatrics’ Adolescent Sleep Working Group reviewed studies about sleep in teens. Researchers studied the harmful effects of not getting enough sleep-anything less than 8.5 to 9 hours of sleep on school nights-could have on young people. They discovered not getting enough sleep may cause poor grades at school. Not getting enough sleep has also been connected to a higher risk of car accidents in teens.

It may seem as though the way to solve the problem would be for teens to just go to sleep earlier. But researchers say that isn’t likely to work. Teens experience physical changes that make falling asleep earlier difficult. Their biological (生物的) clocks just won't allow them to fall asleep at 8 p.m., even when they’re tired.

Studies have shown that just delaying (推迟) school by 30 minutes can have a great effect on a teen's health and performance. So most researchers suggest the school start time be delayed until at least 8:30 a.m. for teenagers.

Some of the benefits could include:

·Teens may be more likely to get the necessary amount of sleep.

·The delayed start time could help teens sleep during their natural sleep.

·Teens may be less likely to depend on coffee to stay awake during the day.

·Enough sleep could help teens study better in class, which could help them do better in exams.

·Sleeping longer could reduce health problems caused by a lack of sleep in the long run.

·Getting home later in the afternoon may reduce the amount of time when some teens are home alone, and could reduce the possibility that tens will take part in unhealthy activities.

But doing that can also cause some problems.

3 . It's likely that you don't think you've invited a spy into your home when setting up a new TV. But new Samsung, LG, and Vizio smart TVs can record and share everything that's viewed, whether it's a broadcast or something streaming from the Internet. And some smart TVs can even track what DVD you're watching.

Your viewing habits are valuable information for marketers who might want to use the information to advertise new shows and products, offer extra content on shows you want to watch. The advertisements are like the ones you see on your computer.

You might not realize that you allowed TVs to collect your viewing habits when you agreed to the long privacy policy during setup. With Samsung, there are 47 screens of text. LG and Vizio also ask you to agree to the privacy policy in thousands of words in fine print.

When Consumer Reports emailed the makers to ask how they are using the technology, representatives for Samsung and Vizio didn't say anything. An LG representative said that the company isn't using any data to send personalized ads and has no plans to do so. But Consumer Reports says that could change at any time.

You might think, “How can I turn those advertisements off?" It's not always so easy. To stop tracking, you have to fight your way through menu settings. On an LG set, go to settings , then options, then Live plus, click off, then close. With Vizio, it's like a long tour through three menus to turn off the advertisements. With Samsung, it's a similar trip to find the box "SyncPlus and Marketing” to disable it.

Consumer Reports says that countermanding the marketing feature may cause you to lose some extra services from makers, but it's more important to protect your privacy.

1. What will the marketers use customers' viewing habits to do?

A．Build a good relationship with customers.	B．Collect some suggestions about shows.
C．Advertise new shows and products.	D．Improve the quality of smart TVs.

2. How does Consumer Reports think of what the LG representative said?

A．Supportive.

B．Doubtful.

C．Reasonable.

D．Believable.

3. What's the main idea of paragraph 5?

A．How we learn to use TVs’ settings.

B．How we can get more shows from TV.

C．How we send personal information to others.

D．How we stop advertisements from appearing on the screen.

4. Which word can replace the underlined word "countermanding" in the last paragraph?

A．cancelling

B．reading

C．researching

D．learning

4 . The word “sport” first meant something that people did in their free time. Later it often meant hunting wild animals and birds. About a hundred years ago the word was first used for organized games. This is the usual meaning of the word today. People spend a lot of time playing football, basketball, tennis and many other sports. Such people play because they leant to. A few people are paid for sport they play. These people are called professional sportsmen. They may be sportsmen for only a few years, but during that time the best ones can earn a lot of money. For example, a professional football player in England earns more than 300,000 dollars a year. The stars earn a lot more. International golf and tennis champions can make more than 500,000 dollars a year. Of course, only a few sportsmen can earn as much as that.

Perhaps the most surprising thing about sportsmen and money is that the stars can earn more money from advertising than from sports. An advertisement for sports equipment does not simply mean, “Buy our things”. It says, “Buy the same shirt and shoes as…” Famous sportsmen can even advertise things like watches and food. They allow the companies to use their names or a photo of them and they are paid for this. Sport is no longer just something for people’s spare time.

1. From the passage we can learn that            .

A．famous people spend too much money and time on sports

B．the development of sports is slower than any other activity

C．most people enjoy sports because they can earn a lot of money

D．now sports is not only an amusement for people

2. In this passage “professional sportsmen” means people “_____________”.

A．who teach others how to make money in sports

B．who take sports as their jobs

C．who are very fond of sports

D．who teach other sportsmen how to play sports

3. Now, the “sport” means                  .

A．what most of the people do in their spare time

B．hunting wild animals and birds in the forests

C．organized games

D．something that people are paid to

4. Which of the following is TRUE?

A．Most people play sports only for money.

B．Those who play sports earn more than those who do not.

C．People play sports for different purposes.

D．Those who play sports want to keep strong and fit.

5 . Football is my favorite sport. I loved to watch it, but I had never played in a football game before I went to college. I lacked self－confidence and I doubted if I could do well in a team, which was why I hardly did sports together with others. I just loved practicing playing football in the backyard of my house.

About one month after I went to college, one day some of my classmates said they'd play a football game with some players of another class. I really looked forward to it but never thought I'd join them to play. That day finally came and I went to watch with my classmates. However, just about ten minutes after the game started, one member of our football team got injured and could no longer play. The other members looked worried. Then one of them came to me and asked, “Can you play?” At first, I shook my head, but then I nodded. “Great! Come and play,” he said. I followed him, having no idea at all what to do. To my joy, he asked me to play in defense (防守). Defense was my favorite because I found it more fun and less complicated (复杂的). Then the game began again. There weren't a lot of big kids on the offensive line (攻击线) of the other team and I suddenly gained some self－confidence. About five minutes later, the ball was kicked toward the guard. I thought it was a good opportunity for me. I quickly ran past the guard and got the ball. When the guard came to the offensive line, I kicked the ball. I scored and all my classmates cheered. You may not believe it, but I scored twice that time. The final score was 6—2 and we won. My teammates thought that I did very well and none of them believed I hadn't played in a game before.

That game really changed me. I am a really confident person now and often play football games with my teammates.

6 . Should you listen to music when you work?

Do you like to listen to music when you work?

Ask this question at a party, and you’ll probably get _________ responses. Some will say they love it, claiming that it improves their performance; others will say they find it distracting (分散注意力的) and cannot work _________ with music playing in the background.

Interestingly enough, our research has found that both of these viewpoints can be true. It just _________ on what sort of work you’re doing.

In a recent study, we brought participants into our lab to perform a variety of tasks. They included a(n) _________ task-searching through word lists and crossing out words containing the letter “a” and a more difficult task—memorizing word pairs and _________ word to its partner. Some participants completed all of the tasks in silence, _________ others completed the tasks with instrumental music that was cither loud or soft, and either simple or complex, the latter meaning music with more instruments being played. Several key findings _________ from our study.

We found that participants who listened to simple music or no music performed about the same on the easy task. However, participants who listened to _________ music performed best on the easy task.

On the contrary, participants performed worse on the more difficult task when they listened to any music, regardless of complexity or volume, compared to those who didn’t listen to any music.

How should we _________ these findings?

We suggest that people have limited mental resources from which both __________ and tasks can draw. We can become __________ and our minds may wander when these resources are not fully used. But we also can become over-excited and __________ when these resources are used up.

Not surprisingly, we typically need to use fewer of our mental resources when we perform easy tasks, whereas demanding tasks require more brainpower. However, because we might be less __________ during easier tasks, there’s a greater risk of drifting off. Music might give us the extra __________ we need to overcome the monotony (单调). However, difficult tasks already demand lot of our resources. Listening to music can become too much.

So best __________ should appear when we strike “sweet spot,” which may depend on the type of music and the type of task.

7 . In 2015, Chennai was destroyed by one of the worst floods in over a century, leaving thousands without food, water and supplies. During the flood, many heroes arose, one of whom was Santosh, a young man who owned a take-out restaurant in Chennai.

When the first flood hit in November, he got a call from a company called Naga Rava. The company asked him to prepare 5,000 packets of food and give them to the flood victims. He, with his partners, took the order, cooked for 14 hours and delivered(递送) them. But that night, as they sat together discussing the event of the day, they actually felt ashamed(羞愧). “Here was a man not even from Chennai and he was going out of his way to help the affected people. We, while living here, had not really done anything ourselves for our own people,” said Santosh later.

He then began the groundwork for a collection to help cook more dishes. Little did he know that the November flood was just the beginning, and the real show was about to begin. The December flood affected them all. His own house got flooded and his family was trapped on the second floor. They lost phone connection and electricity. In spite of this, Santosh went back out into the flood, creating a kitchen and preparing food all by himself for the victims.

He did not sleep for four days, taking a one-hour break every day as he kept on cooking. As word got out about this man’s effort, others stepped out to join him. From children to the elderly, strangers came to help him in cooking, packing and transporting food. Up to 300 volunteers worked together to make it all happen. By the time the fourth day finally came to an end, Santosh and his team had prepared 170,000 food boxes and delivered them to people in need.

9 . Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?

UBC Professor Simard explains how trees are much more complex than most of us ever imagined.

Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition “depending on who needs it”.

Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌) networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.

Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.

“We didn’t take any notice of it,” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

1. What can we learn from Professor Simard’s words in paragraph 3?

A．Trees depend on each other.	B．Trees protect their own wealth.
C．Trees compete for survival.	D．Trees provide support for dying trees.

2. Why are “Mother trees” extremely important?

A．Because they know more about the complex “tree societies”.

B．Because they seem more likely to be cut down by humans.

C．Because they look the largest in size in the forest.

D．Because they pass on nutrition to young trees.

3. What does the underlined word “it” in the last paragraph refer to?

A．How young trees survive.	B．How “tree societies” work.
C．How forestry industry develops.	D．How trees grow old.

4. What would be the best title for the passage?

A．Old Trees Communicate Like Humans.

B．Young Trees Are in Need of Protection.

C．Trees Are More Fantastic Than You Think.

D．Trees Contribute to Our Society.

10 . If Confucius(孔子)were still alive today and could celebrate his September 28 birthday with a big cake, there would be a lot of candles. He'd need a fan or a strong wind to help him put them out.

While many people in China will remember Confucius on his special day, few people in the United States will give him a passing thought. It's nothing personal. Most Americans don't even remember the birthdays of their own national heroes.

But this doesn't mean that Americans don't care about Confucius. In many ways he has become a bridge that foreigners must cross if they want to reach a deeper understanding of China.

In the past two decades, the Chinese studies programs have gained huge popularity in Western universities. More recently, the Chinese government has set up Confucius Institutes in more than 80 countries. These schools teach both Chinese language and culture. The main courses of Chinese culture usually include Chinese art, history and

philosophy(哲学). Some social scientists suggest that Westerners should take advantage of the ancient Chinese wisdom to make up for the drawbacks(缺陷)of Western philosophy. Students in the United States, at the same time, are racing to learn Chinese. So they will be ready for life in a world where China is an equal power with the United States. Businessmen who hope to make money in China are reading books about Confucius to understand their Chinese customers.

So the old thinker's ideas are still alive and well.

Today China attracts the West more than ever, and it will need more teachers to introduce Confucius and Chinese culture to the West.

As for the old thinker, he will not soon be forgotten by people in the West, even if his birthday is.

1. The opening paragraph is mainly intended to______________.

A．provide some key facts about Confucius

A．Forgotten Wisdom in America

B．Huge Fans of the Chinese Language

C．Chinese Culture for Westerners

D．Old Thinker with a Big Future

4. The passage is likely to appear in__________.

A．a personal biography	B．a history paper
