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.
3.From the passage we can infer_______
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
D. the genetic structure of mice is totally different from that of people
4.What’s the best title of the passage?
A. Living a sweet life
B. Kids consume much more sugar
C. Genetic structure of humans
D. Danger of sugar

This could be the perfect gift for the partner, who embarrasses you on the dance floor. Smart socks, which can teach to dance, may be the answer for anyone with two left feet.
The socks have been developed as a running tool to help runners improve their skills. Thanks to the socks, users can accurately（精确地） record not only know far and fast they run but also how well. It means the user maximizes(最大化)their performance, and reduces damage to body and prevents hurt. The hi-tech socks are made of special fibers(纤维) that watch the movements of your feet. They look, feel and can be washed like normal clothes.
Sensors record each movement and send it by an ankle transmitter (脚踝发射器) to a smart phone. Then a “virtual coach” application shows the information and can tell the user what they are doing wrong, and help to improve skill in any task with feet.
The socks should be useful to athletes and weekend joggers. “People think running is so easy and of course everybody can do it but not necessarily safely and well,” Dr Davide Vigano said. A recent study showed that between 60 and 80 percent of runners got hurt per year. This is pretty much more than any other human activity. Researchers say the technology can also be developed to teach people how to dance, play sports such golf, or even to help to teach women to walk better in high heels.
Mr. Vigano said, “People could all benefit from the idea. We have had interest from all sorts of sports, like skiing, football, cycling and golf. Anything where you have to use your feet can use it. It could even be put in high heels to help women walk in them safely.”
Socks are just the start, and the technology could be used in gloves, hats and boots. The socks, anklet and software package, are expected to be sold for around ￡120, which will go on sale in March.
1.What does the underlined part “anyone with two left feet” refer to?
A. People who are disabled.
B. People who invented the socks.
C. People who are not good at dancing.
D. People who are interested in dancing.
2.What’s special about fibers that the socks are made of ?
A. They can monitor the movement of feet.
B. They feel much softer than normal clothes.
C. They are expensive to produce.
D. They act as a smart phone for users.
3.According to Dr Vigano, _____
A. 60 to 80 percent of runners would like to buy the smart socks.
B. users can run as fast as they like with the socks.
C. everyone can make good use of the smart socks.
D. no runners will get hurt, thanks to the socks.

Before the law sits a gatekeeper. To this gatekeeper comes a man from the country who asks to gain entry into the law. But the gatekeeper says that he cannot grant him entry at the moment. The man thinks about it and then asks if he will be allowed to come in sometime later on. "It is possible," says the gatekeeper, "but not now." The gate to the law stands open, as always, and the gatekeeper walks to the side, so the man bends over in order to see through the gate into the inside. When the gatekeeper notices that, he laughs and says: "If it tempts you so much, try going inside in spite of my prohibition. But take note. I am powerful. And I am only the most lowly gatekeeper. But from room to room stand gatekeepers, each more powerful than the other. I cannot endure even one glimpse of the third."
The man from the country has not expected such difficulties: the law should always be accessible for everyone, he thinks, but as he now looks more closely at the gatekeeper in his fur coat, at his large pointed nose and his long, thin, black Tartar's beard, he decides that it would be better to wait until he gets permission to go inside. The gatekeeper gives him a stool and allows him to sit down at the side in front of the gate. There he sits for days and years. He makes many attempts to be let in, and he wears the gatekeeper out with his requests. The gatekeeper often interrogates him briefly, questioning him about his homeland and many other things, but they are indifferent questions, the kind great men put, and at the end he always tells him once more that he cannot let him inside yet. The man, who has equipped himself with many things for his journey, spends everything, no matter how valuable, to win over the gatekeeper. The latter takes it all but, as he does so, says, "I am taking this only so that you do not think you have failed to do anything."
During the many years the man observes the gatekeeper almost continuously. He forgets the other gatekeepers, and this first one seems to him the only barrier for entry into the law. He curses the unlucky circumstance, in the first years thoughtlessly and out loud; later, as he grows old, he only mumbles to himself. He becomes childish and, since in the long years studying the gatekeeper he has also come to know the fléas ( PZ) in his fur collar, he even asks the fleas to help him persuade the gatekeeper. Finally his eyesight grows weak, and he does not know whether things are really darker around him or whether his eyes are merely deceiving him. But he recognizes now in the darkness a ray of light which breaks out of the gateway to the law. Now he no longer has much time to live.
Before his death he gathers in his head all his experiences of the entire time up into one question which he has not yet put to the gatekeeper. He waves to him, since he can no longer lift up his stiffening body. The gatekeeper has to bend way down to him, for the great difference has changed things considerably to the disadvantage of the man. 
"You are insatiable (不知足的)."t "Everyone strives after the law," says the man, "so how is it that in these many years no one except me has requested entry?" The gatekeeper sees that the man is already dying and, in order to reach his diminishing sense of hearing, he shouts at him, "Here no one else can gain entry, since this entrance was assigned only to you. I'm going now to close it. " 
1.Which can best describe the man from the country?
A.Brave but innocent. B. Loyal but ridiculous.
C. Tolerant but stubborn. D. Trustworthy but childish.
2.hat is the implied meaning of the underlined sentences?
A. Anyone who breaks the law will get severe punishment.
B. It's next to impossible for people to gain entry into the law.
C. The gatekeepers are powerful enough to defend the law.
D. All the gatekeepers take full responsibility for obeying the law.
3.The sentence "What do you still want to know now?" asks the gatekeeper. can be put in
A．① B. ② C. ③ D④
4.Which of the following is TRUE?
A.The gatekeeper is actually the symbol of responsibility.
B. All efforts made by the man from the country are in vain.
C. The man from the country finally gains access into the law.
D. A close relationship is formed between the gatekeeper and the man.
5.Why is the man from the country eager to have access to the law continuously?
A.Because he is anxious to explore the nature of law. .
B.Because no one can gain entry into the law except him.
C. Because the gatekeeper promises him entry into the law.
D. Because he knows how to take advantage of the gatekeeper.
6.What may be the title of the novel?
A. Before the law B. Above the law
C. A countryman's life D. A gatekeeper's duty

Your smart phone may have hurt you before you realize it. Don't be addicted to it. Put your phone away, OK?
1.Cyber Sickness
Also called “digital motion sickness”, symptoms that range from headaches to woozy feelings can occur when you quickly scroll on your smart phone or watch action packed video on your screen. 1.. Your sense of balance is different from other senses in that it has lots of inputs. When those inputs don’t agree, that’s when you feel dizziness and sickness.
2. Text Claw
It is the unofficial term for soreness and muscle contraction felt in the finger, wrist and forearm after heavy smart phone use. 2.. So if you’re always on your phone, it makes sense to feel discomfort in your hands and forearms.
3. Eye Strain
Do you stare at a screen for hours on end? If you’re reading this, you very well might. 3.. Staring at your digital devices for a long time can lead to dry eyes, headaches and tiredness, which can decrease your productivity. Experts suggest taking screen breaks every 20 minutes.
4. Text Neck
Similar to the claw, text neck---discomfort in the neck and spine happens when you spend a long time looking down at your smart phone. 4.. Being mindful of how far your neck bends when you’re on your phone---- and bending it back to an upright position can help reduce the risk of text neck.
5. Pedestrian safety
Pedestrian deaths are on the rise because too many smart phone users engage in distracted walking. While focused on the cyber world, many of us can lose reality of the physical one. Elemental pedestrian safety knowledge is compromised by technology, and the risks are scary. 5..
A. We should taking breaks for a while.
B. The sensation results from a mismatch between sensory inputs.
C. Remember that pedestrian safety is more important than smart phone.
D. The habit may lead to people requiring medical spine care at a younger age.
E. To avoid injury or worse, put your phone away until you’ve reached a safe spot.
F. Any specific motor activity can cause pain in the tendons (筋) and muscles when done repeatedly.
G. Any activity that requires active use of your eyes---driving and reading included---can cause eye tiredness.
