1 . The Internet plays a big part in human life. We use it for work and pleasure. We use it to learn a new language. We find advice on it. We use it to connect with family and friends. We use it to stay in touch with events we care about.The list goes on and on.

As far as the Internet being a part of our lives, well, that train has left the station. There is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected to high blood pressure in a young group: teenagers.

The study results show that teens who spend at least 14 hours a week only online may cause high blood pressure, which makes their hearts and blood vessels(血管) work too hard. Over time, this extra pressure increases the risk of a heart attack. High blood pressure can also cause heart and other diseases.

The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people, from 14 to 17 years old, took part in it. 134 of the teens were described as “heavy Internet users”. And researchers found that out of these 134 teens, 26 had high blood pressure. The researchers said the study was the first to connect heavy Web use with high blood pressure.

The lead researcher is Andrea Cassidy-Bushrow. She says, “Using the Internet is part of our daily life, but it shouldn’t ruin(毁坏) us.” Ms. Cassidy-Bushrow adds that it is important for teens to stop to have a rest regular from their computers or smartphones and do some kind of physical activity. She also suggests that parents shouldn’t let their children use the Internet for more than two hours a day, five days a week.

2 . Kids and science seem to be made for each other!

The basic science is a combination of thought and experiment called the scientific method. It’s where you start with an idea, create a way to prove or disprove your idea, and show what you learned based on facts. Learning to follow this process helps you think logically and carefully. These important thinking skills can be used in many areas of study. To give a child practice with these thinking skills is like giving vitamins to a developing mind.

One of the greatest things we can teach our children is to love learning. Learning science is a great way to do so. Children are easy to be interested in science. Because much of science is hands-on, it attracts most children. Nothing makes a child sit up and take notice like the “WOW!” of a great science showing.

Science opens doors to many subjects at school. Building love for science can be helpful in other areas of study. For example, one cannot love science for very long without becoming good at its language-math! So science encourages children to study math. An interest in science is an interest in how things were once understood compared to how they are understood now. Thus studying science lends itself easily to studying history. And after you do an experiment, you need to write a lab report. Therefore, writing becomes an important part of science.

Science is the basic thing for much of our life. The science of farming shows how our food is produced; biomedical science keeps us healthy; even our beds these days are designed according to scientific facts. We almost eat, sleep and breathe with the help of science! When we prepare the next generation of voters, creators and policy makers, it is important to make sure they are not only comfortable but also good at science.

3 . Many children first learn the value of money by receiving an allowance. The purpose is to let children learn from experience at an age when financial mistakes are not very costly.

The amount of money that parents give to their children to spend as they wish differs from family to family. Timing is another consideration. Some children get a weekly allowance. Others get a monthly allowance.

In any case, parents should make clear what, if anything, the child is expected to pay for with the money.

At first, young children may spend all of their allowance soon after they receive it. If they do this, they will learn the hard way that spending must be done within a budget. Parents are usually advised not to offer more money until the next allowance.

The object is to show young people that a budget demands choices between spending and saving. Older children may be responsible enough to save money for larger costs, like clothing or electronics.

Many people who have written on the subject of allowances say it is not a good idea to pay your child for work around the home. These jobs are a normal part of family life.

Paying children to do extra work around the house, however, can be useful. It can even provide an understanding of how a business works.

Allowances give children a chance to experience the three things they can do with money. They can share it in the form of gifts or giving it to a good cause. They can spend it by buying things they want. Or they can save it.

1. What is special about children learning financial management by experience?

A．They learn more quickly.

B．They are not as likely to make mistakes.

C．Their mistakes won't matter so much.

D．They have plans made by their parents.

2. When the writer says some young children "will learn the hard way that..." in Para. 4, he means ________ .

D．their parents will teach them a hard lesson

3. Judging from the article, it is all right if a couple give their son an allowance ________ .

A．regularly twice every month

B．whenever he has run out of money

4. The writer would agree to encourage the kids to ________ to deal with a tight budget.

A．borrow money from others	B．ask their parents for more money
C．get paid for their household routines	D．earn money by extra work

4 . Music died here last spring，or rather，it was killed by members of the school committee who ignored the importance of music and drama as part of the high school curriculum.

The committee decide that teaching students how to take a standardized test is more important than a curriculum in which students can explore their interests in the arts.Because the school system is running out of funding，it needs to make sure that students pass the test or even more money will be lost.If students fail the state standardized test，it is not the fault of drama and music classes.They are failing because the“academic”classes are in deficiency in a way.

It is painful to think of how many students will be discouraged from singing，acting，and playing instruments because school programs are no longer offered.Many families cannot afford private music lessons，and many potential musicians and artists may not find their callings if they are not exposed to the arts in school.The fact that the school committee thinks the arts are not worth the investment will certainly make some students believe the arts are not worth their time or support and the cycle will continue.

Teaching for a test does not shape students into well rounded people.It blocks the natural sense to create and express feelings through the arts—there is more to life than the analytical thinking that math and English provide.What happens after a test？Sure，a student might graduate，but they will have limited knowledge—certainly not a good preparation for the real world.

1. Music and drama are removed from the high school curriculum in that________.

A．some students fail the state standardized test

B．fewer and fewer students love to attend them

5 .    “All work and no play make Jack a dull boy.” But now scientists have given us an other warning: too much play with smart phones or computers makes you dull too.

“Many focus on the benefits of digital devices（设备）in education but ignore the costs”, said Patricia Greenfield from the University of California, “losing the ability to understand the emotions of other people is one of the costs.” Greenfield and her research team did an experiment. They worked with 105 children who spend about 4.5 hours in front of screens on a school day. The students were asked to describe the emotions towards the pictures of people who were happy, sad, angry or scared. Then, half of them attended a five-day nature and science camp. There they had no smart phones, TV, or computers. The other half stayed in school and spent the five days as usual. Five days later, all the children took the test again.

Students who had been to the camp got about 5 percent more answers correct than they had done before the camp. But the other group of students didn't show much improvement. The study is not perfect in some ways, said the researchers. But scientists say that the study is still a warning for us.

“Emotional skills develop in practice and the brain develops through real interaction.” said Professor Taylor, a professor at the University of San Francisco.

Researchers talked to 2,000 parents of children aged 2-16 in the UK about what activities their children could do confidently. The results were surprising: Their children could use a tablet(平板电脑)(59%)and work a mobile phone(57%)more confidently than they could tie their shoe laces(鞋带)(53%)! So, spend more time away from mobile phones and computers if you want to be an understanding friend, and not a member of what the Daily Mail called “Generation Helpless”.

6 . 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.

1. What does Paragraph 1 show?

A．Today’s teens have poor grades at school.

B．Teens should get at least 8.5 hours of sleep daily.

C．Today’s teens are in danger because of car accidents.

D．Teens can be negatively influenced by not getting enough sleep.

3. Why can’t teens fall asleep earlier?

A．Because their homework is too much,

B．Because they love staying up late at night.

C．Because their physical changes make it hard.

D．Because they have unbalanced biological clocks.

4. What would the text most probably talk about next?

A．The disadvantages of starting school later.

B．The benefits of getting enough sleep for students.

C．The methods of helping students get enough sleep.

D．The advantages of putting off the school start time.

7 . “Do not tell anyone”. We often hear these words when someone tells us a secret. But keeping a secret is hard. We’re often tempted（引诱）to “spill the beans”, even if we regret it later.

According to the professor, Asim Shah, keeping a secret may well “become a burden”. This is because people often have an “eager and anxious urge（冲动）to share it with someone”. An earlier study, led by Anita, a scientist at the University of Notre Dame, US, suggested that keeping a secret could cause stress. People entrusted（托付）with secrets can suffer from depression, anxiety, and body aches, reported the Daily Mail.

Secrets are so often getting out. Why do people share them at all? Shah explained that people often feel that it will help them keep a person as a friend. Another reason people share secrets is guilt over keeping it from someone close to them. A sense of distrust can develop when people who are close do not share it with each other. “Keeping or sharing secrets often puts people in a position of either gaining or losing the trust of someone, ”according to Shah.

He added that talkative people could let secrets slip out. But this doesn’t mean that it is a good idea only to share secrets with quiet people. A quiet person may be someone who keeps everything inside. To tell such a person a secret may cause them stress, and make them talk about the secret.

Shah said that to judge whether to tell someone a secret, you’d better put yourself in their position, Think about how you would feel to be told that you mustn’t give the information away. Shah also recommended that if you accidentally give up someone’s secret you should come clean about it. Let the person know that their secret isn’t so secret anymore.

1. Why does the author say keeping a secret may “become a burden”?

A．Because people are born not to be able to keep secrets.

B．Because when people have secrets, their bodies ache.

C．Because keeping secrets is certain to cause depression.

D．Because keeping secrets could probably be harmful to health.

A．To fall by accident.	B．To let out secrets on purpose.
C．To spread secrets to everyone around.	D．To give away secrets unintentionally.

4. What can we learn from the passage?

A．Quiet people are more likely to keep the secrets to themselves.

B．Sharing secrets helps establish friendship or get over the, sense of guilt.

C．Putting yourself in others’ shoes helps realize the importance of keeping secrets.

D．A person who is asked to keep a secret will suffer from psychological problems only.

8 . It has always been thought that when it comes to tornadoes, the most peaceful place is the centre: the eye of the storm. But a photo taken this week in the small Canadian town of Three Hills, Alberta, suggests that there is perhaps no place more peaceful than inside the calm mind of Theunis Wessels.

It all started when Mr Wessels’ wife, Cecilia, was warned by their nine-year-old daughter that he was cutting grass in their yard when a violent tornado appeared in the distance. When her husband refused to come inside, saying it was moving away from them, Mrs Wessels took a photo to show her parents the storm. The photo, which has been shared widely on social media, is a masterclass in calmness.

In it, the sockless Mr Wessels, dressed casually in summer shorts and sunglasses, is seen never being upset by the disastrous column of cloud. “I took the picture just to show my mum and dad in South Africa, ‘Look, there’s a tornado,’ and now everyone is like, Why is your husband cutting the grass?” Cecilia told the Times Colonist.

When asked later about the tornado’s approach to him, Mr Wessels responded, “I was keeping an eye on it,” seeming as cool as his gardening style and attracting more than a little respect. “Alberta, Canada,” wrote one admiring Twitter user, “where men face the elements and do what needs to be done.” A writer for Esquire magazine struck a pensive note: “I can understand Theunis,” Peter Wade admitted, “sometimes when the world is raging outside, the only thing you can do is keep your small area of it.”

1. How is Paragraph one developed?

A．By listing theories.	B．By giving examples.
C．By analyzing causes.	D．By making comparisons.

2. Why did Cecilia take the photo?

A．To post it on social media.	B．To record her husband’s heroic act.
C．To inform her parents of the tornado.	D．To prove what is the most peaceful place.

3. Which may make Mr. Wessels respected?

A．His way of gardening.	B．His calmness in the face of a tornado.
C．His bravery in fighting the tornado.	D．His rich knowledge about tornado.

4. What is the main idea of the passage?

A．A man ignored a tornado in Canada.	B．There are some features of tornado in Canada.
C．A man survived surprisingly from a tornado.	D．A picture caused heated discussions.

9 . In 2014，AIA（American Institute of Architects）launched a large-scale awareness-building effort to educate the public about architects' impact on society. Five years later，the Blueprint for Better campaign has become an institute-wide program     1     seeks to connect architects with the public. Through innovative partnerships with the Architecture and Design Film Festival，Wired magazine，and Chicago Ideas Week，AIA has engaged plenty of individuals，ranging     2     working architects to government leaders to school children，encouraging them to design a Blueprint for Better together. The AIA Film chrallenge now in its     3    （five）year，is a good example of success，     4     （yield）   more than 240 documentary short films and hundreds of thousands of people's choice votes. Each summer，filmmakers and architects     5    （invite）to tell stories about the important design work happening in their communities. Winning films in recent challenges have explored affordable housing     6     （solve） in cities like Philadelphia and Los Angeles. Others have shed light on the need to save important     7    （culture）spaces and practices from Cleveland to Hawaii. Films     8    （submit） from around the world have shown how design can overcome challenges related to public health，homelessness，climate change and equity（公平）.

But what about these films really speak to viewers? As     9     audiovisual medium，film is     10    （probable）the only one that comes close to conveying the experience of the built environment. When pictures of the spaces we live in is layered with stories，the power of architecture can be understood in a new way.
