    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.

    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

    Walk through the Amazon rainforest today and you will find it steamy, warm, damp and thick. But if you had been there around 15,000 years ago, during the last ice age, would it have been the same? For more than 30 years, scientists have been arguing about how rainforests might have reacted to the cold, dry climate of the ice ages, but till now, no one has reached a satisfying answer.

    Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to solve global warming. Currently the trees in the Amazon take in around 500 million tons of CO2 each year: equal to the total amount of CO2 given off in the UK each year. But how will the Amazon react to the future climate change? If it gets drier, will it survive and continue to draw down CO2? Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past.

    Unfortunately, collecting information is incredibly difficult. To study the past climate, scientists need to look at fossilized pollen（花粉）kept in lake mud, Going back to the last ice age means drilling down into lake sediments（沉淀物）, which requires specialized equipment and heavy machinery. There are very few roads and paths, or places to land helicopters and aeroplanes. Rivers tend to be the easiest way to enter the forest, but this still leaves vast areas between the rivers completely unsampled（未取样）. So far, only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon forest reacts to climate change.

    1.How do scientists study the past climate change?

    A. By predicting the climate change in the future.

    B. By drilling down deep into land sediments.

    C. By analyzing fossilized pollen in lake mud.

    D. By taking samples from rivers in the Amazon.

    2.Why is it difficult to collect information about the past climate change?

    A. Because scientists can't find proper equipment and machinery.

    B. Because it is very difficult to obtain complete samples.

    C. Because helicopters and aeroplanes have no place to land.

    D. Because none of the cores provide any information.

    3.Where is the passage most probably taken from?

    A. A medical journal. B. A news report

    C. A travel brochure. D. A science magazine.

    4.The best title for the text may be .

    A. Secrets of the Rainforest

    B. Climates of the Amazon

    C. The History of the Rainforest

    D. Changes of the Rainforest

    While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted-being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer!

    About a year ago, NASA offered $125,000 to Anjan Contractor, a 3-D technology expert, to build a device（设备）that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens.

    Late last year, the engineer presented a video of his first prototype（原型）that begins by creating a single slice of dough（面团）that is cooked and printed at the same time. Then comes the tomato “sauce” —a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn’t show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds.

    While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That’s because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not.

    Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients（配料）and then they are reduced to the powder form. This, as you can imagine, will not be so easy. But, while the printer may not be ready for space, it certainly looks ready enough for people on earth. Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars!

    1.Why does the author mention the things that astronauts in space cannot do?

    A．To ask us not to take common things for granted.

    B．To show they live a difficult life there.

    C．To show their life is boring in space.

    D．To introduce the topic of the text.

    2.NASA offered $125,000 to Anjan Contractor mainly to __________.

    A．create some new type of 3-D printer

    B．attract more companies to work for NASA

    C．help astronauts in space enjoy fresh pizza one day

    D．produce pizza in large quantities to earn great profits

    3.The biggest challenge that Anjan Contractor is faced with now is probably that __________.

    A．he has no money left to go on with his research

    B．the pizza doesn’t seem appetizing to pizza lovers

    C．he has no way to make pizza that can last for thirty years

    D．he cannot make the food container last for decades

    4.What’s the best title of the passage?

    A．NASA is trying its best to help astronauts eat better

    B．Astronauts may soon be able to enjoy steaming hot pizza

    C．NASA is working on making pizza for common people

    D．A 3-D pizza printer has been used to make pizza
