We live in a sweet world. The average American kid consumes more than 20 teaspoons of sugar per day, and adults eat 50% more sugar today than they did in the 1970s. We all know that too much sugar isn’t good for you. But did we know it could be dangerous? A team of researchers at the University of Utah used mice to conduct a study on the negative effects of sugar. They found it could have serious effects on people’s health.
Sugar is found not only in sweets and candies, but also in many household items like pasta and crackers.
During the 58-week-long study, mice were fed a diet containing 25% more sugar. This percentage equals a healthy human diet along with three cans of soda daily. The team found that these mice were twice as likely to die as mice fed a similar diet without the sugar. Though the mice did not show signs of obesity or high blood pressure, male mice were 26% less territorial and produced 25% fewer offspring than the other mice.
Scientists often use mice for research because they have a similar genetic(基因) structure to humans. “Since most substances that are dangerous in mice are also dangerous in people, it’s likely that those physical problems that cause those mice to have increased deaths also work in people,” says study author James Ruff of the University of Utah. Findings from this study reveal negative effects that are not as noticeable as weight gain or heart problems. Sugar can contribute to long-term changes in the body that can change development and even shorten lives.
Cutting sugar out of the American diet altogether may be difficult. But making the effort to control our nation’s sugar desire will provide for a truly sweeter future.
1.The study conducted by researchers aimed at learning about________
A. the advantages and disadvantages of sugar
B. the negative effects of sugar on people’s health
C. the genetic structure of mice
D. American’s diet
2.According to the study, which of the following statements is wrong?
A. Sugar can even shorten lives.
B. Sugar’s negative effects are not noticeable.
C. Mice are more likely to die when fed a diet containing 25% more sugar.
D. Eating much more sugar can make mice put on weight and get high blood pressure.

A. sugar plays a very important role in Americans’ diet
B. kids consume more sugar than adults in America
C. the study on human beings lasted 58 weeks

The Internet has changed the world we live in dramatically, so that in some ways it is unrecognizable from the place we lived in twenty years ago. Communications have been revolutionized. Not only have cell phones found their way into most people’s pockets or purses, but they are also used for next messaging and as cameras. Long distance phone calls have been replaced by e-mail and video conferencing. Communications, person to person or company to company, have turned into a fast-paced exchange with instant response. In fact, it has become more convenient and efficient.
The other kind of communication the Internet provides is information. School children and medical researchers alike will tell you that they could not work without the Internet and its ability to connect them to any number of websites and databases of information. Many people do their banking on-line. Others plan a trip and book a flight for themselves. People do their own stock trading through the Net. Sports fans follow scores and statistics on websites. Political junkies(政治狂) gather campaign statements and debate topics, even between elections. And almost everyone who owns a computer and has Internet access has bought at least one item on-line. No wonder some young people can not imagine what life was like before the Internet.
Some Advantages of the Internet
I. ________1.________ of the Internet communication
●A fast-paced exchange replacing long distance phone calls with ________2.________ like e-mail and vedio conferencing

In today’s consumer world, we’ve never had so much, yet it seems we’ve never been so unsatisfied. The cost of housing has been rising for decades, and the cost to the planet has been huge, too. But there is a way to live a simpler, greener, and more affordable life: buy a TinyDwelling home!
TinyDwelling homes are very small, yet comfortable houses at affordable prices. Each TinyDwelling home has a contemporary design and included a living room, kitchen, bathroom, upstairs sleeping area, and convenient storage space. TinyDwelling homes are cheap to run and ecologically-friendly, too. All you need is a small heater to keep your house warm in cold weather, and solar panels (太阳能电池板) in order to provide light and electricity.
TinyDwelling is part of the small-living movement that began in the late 1990s. Back then, a growing number of people began to live in very small homes. They wanted to reduce their possessions, living space, and energy costs, so as to lead more ecologically-friendly lives. But the small-living movement really took off after the economic crisis of 2008, when many people realized that they couldn’t afford to keep large homes.
Lizzy Morriaon, a small-living enthusiast, started TinyDwelling homes in 2008 to meet the needs of these people. Since then, Lizzy has been designing and building homes nonstop, and TinyDwelling homes have become so popular that thousands of people have bought one. And Lizzy hasn’t only designing and building houses. She has also been teaching people how to build them.

We live in a dangerous world. The figures for crime go up year by year. If you were attacked in the street, would you be able to defend yourself? Not very well probably, especially if someone was pointing a gun at you. We all see a lot of violence of films, but recently some programs on television showed how people can defend themselves without guns. For example, in one film a woman was attacked from behind. She threw the man, who was heavier and stronger than she was, over her head. Then she held him tightly on the ground. How? She knew Judo.
Jiu-jitsu, as judo is sometimes called, means "muscle science" in Japanese. The student of judo needs to learn a lot about the body, its bones and muscles. Judo uses a number of "falls", "holds" and "throws". Someone who does not know judo cannot defend himself against them. If you know judo you can defend yourself against a person who is stronger than you. You had better not practice judo on your friends unless they can fall without hurting themselves! Being strong is one thing, but using the body wisely is another. In judo, you use the other person's body to help you. You "throw" him to the ground and "hold" him there, so that he cannot move. Of course, it takes time and practice, but knowing judo is useful. In a violent world you ought to be able to defend yourself.
1.According to passage, in fact "judo" is ______.
A.the same as "Jiu-jitsu" B.a kind of fighting
C. a kind of muscle science D.is helpful to a strong man
2.Why does the writer say the world is dangerous?
A. The number of violence and crime is increasing every year.
B.Because many people carry guns.
C.Because there too many films.
D.Because people are not able to defend themselves.
3.Which of the following statement is true about the woman in the passage?
A.The woman held the man over her head.
B.The woman was heavier than the man.
C.The woman was able to defend herself.
D.The woman attacked the man from behind.
4.If a man knows judo, he ______.
A.will be good at muscle science.
B.will be able to avoid being attacked from his back.
C.may defeat any strong person.
D.can help himself by using the other person's body
5.What's the best title for this short passage?
A.How to defend oneself B.Violence in films
C.How to practise judo D.Something about judo

Eyesight is the sense that you rely upon the most. Since we live in a world that requires your eyes to routinely stare at the small type and images on cell phones, computer screens, and televisions, it is important for you to improve and protect your eyesight. 1.
Eyes are just like any other part of the body. 2.Similar to other organs, a diet high in fruits and vegetables and low in sugar and fatty foods will go a long way in maintaining healthy eyes.
3.Plan to exercise your eyes when you wake up, before going to bed, or when your eyes are tired. Make sure your hands are clean so that you do not hurt your eyes and your mind is relaxed before starting.
Since you use your eyes every waking moment, give them lots of rest and relaxation by taking breaks throughout the day and getting enough sleep every night to fully rest, repair, and recover your vision. 4. In the short term, it can cause eye strain (疲劳) or dry eyes. In the long term, it can lead to damage to the optic nerve (视觉神经), which can cause pain and damage your vision.
Besides, most jobs nowadays involve some degree of computer usage, meaning almost everyone will be spending time in front of a computer. 5.To avoid this, you’ll have to properly try to limit your screen time by routinely taking breaks and exercising your eyes.
A. They need nutrition to function well.
B. Close your eyes when exercising your eyes.
C. A lack of sleep will weaken your vision health.
D. You can enjoy your vision for the rest of your life.
E. Unfortunately, this can result in eye strain or injury.

Most of us spend our lives seeking the natural world. We go fishing, sit in the garden, have a picnic, live in the suburbs or go to the seaside. The most popular leisure activity in Britain is going for a walk. When joggers jog, they don't run the streets. Every one of them tend to go to the park or the river.
But despite this, our children are growing up naturedeprived(剥夺). I spent my boyhood climbing trees. These days, children are robbed of these ancient freedoms, due to problems like crime, traffic, the loss of the open spaces and strange new ideas about what is best for children, that is to say, things that can be bought, rather than things that can be found.
The truth is to be found elsewhere. A study in the US: families had moved to better housing and the children were assessed for ADHD—attention deficit hyperactivity disorder(多动症). Those whose accommodation had more natural views showed an improvement of 19%; those who had the same improvement in material surroundings but no nice view improved just 4%.
ADHD is one of the great problems of modern childhood. One study after another indicates that contact with nature gives huge benefits to ADHD children. However, we spend money on drugs rather than on green places.
The life of old people is measurably better when they have access to nature. The increasing concern for the growing population of old people is in quality rather than quantity of years. And study after study finds that a garden is the single most important thing in finding that quality. Even problems with crime and aggressive behaviour are reduced when there is contact with the natural world.
We need the wild world. It is essential to our wellbeing, our health and our happiness.
1.According to the author, people enjoy ________ to seek nature.
A.jogging on the street
B.sitting in the garden
C.shopping in the supermarket
D.running in the gym
2.From the second paragraph, we can see that ________.
A.adults deprive the children of their rights to approach nature
B.climbing trees will certainly do good to the children
C.children probably spend less time in nature nowadays
D.children tend to be happier as a result of their material satisfaction
3.In what way do people benefit from their contact with nature?
A.Children with ADHD can be cured.
B.A garden nearby improves the quality of old people's life.
C.Problems with crime and violent behaviour will easily be solved.
D.Children's performance at school is greatly improved.
4.What is the main idea of this passage?
A.Access to nature improves our life.
B.Nature treats children for ADHD.
C.Getting close to nature reduces crime.
D.Man can't live without natural areas.

Nowadays, we live in a strict and judgmental world where people are quick to point out the faults of others yet seem to ignore their own ones. Some misguided souls believe they have a moral duty to help you be a better person telling you what a failure you really are.
If you're the one placing criticism upon others, please stop. Make a conscious decision, rather than focus on the negative aspect of a person's performance or attitudes, and you can offer helpful suggestions. If I'm painting a living room and making a mess in doing so, I'd have my husband say to me, “This is a tough job. Can I offer a suggestion that might make it easier for you?” rather than have him point out what a careless painter I am.
If you're on the receiving end of criticism, the “OK” response is a perfect solution. When someone comments negatively on a task you're doing, the natural response is to defend and attack.
However, this approach is rarely effective as it puts both parties on the defensive. It diffuses (扩散) a potentially explosive situation. It's important to keep calm and listen without feeling, to be an objective observer. There is much that one can learn from a negative review. You can ask yourself: Could I have done better, and been more thoughtful? Did I give 100% of myself to the task at hand? Is there any truth in what the other person says? If so, how can I improve?
In any event, one should remember the saying, “Stop judging and you will not be judged. Stop condemning and you will not be condemned.” One can learn to be “OK” with criticism and not allow it to negatively impact his or her relationship with the other party. Let it go and that will be “OK”.
1.According to the author, today's people .
A.ignore the mistakes of others
B.focus on how to handle mistakes
C.like to point out the mistakes of others
D.have a moral duty to point out others' faults
2.In Paragraph 2, the author uses the example to show .
A.pointing out a fault needs a skill
B.It's hard to avoid making mistakes
C.we ought to accept others' criticism
D.praise is more important than criticism
3.What is the proper response to criticism in the author's opinion?
A.Paying no attention to it.
B.Learning something from it.
C.Making excuses for your mistakes.
D.Defending and attacking sometimes.
4.Why should you ask yourself some questions mentioned in Paragraph 3?
A.To comfort yourself.
B.To find out your potentials.
C.To make yourself become better.
D.To persuade yourself to admit your mistakes.
5.Which would be the best title for this passage?
A.Is criticism really necessary?
B.What can you learn from criticism?
C.What's the best way to voice criticism?
D.How to criticize and reply to criticism?
