    Are your eyes irritated, dry, watery, blurry, seeing double or sensitive to light, and do your back and neck ache? If so, you are likely one of many people today who suffer from digital eyestrain, also called computer-vision syndrome.

    Eyestrain is often related to the amount of exposure to screens, the distance from eyes to screens and the use of multiple screens simultaneously. However, studies have also shown that the blue light produced by digital devices today reaches further into the eyes than other kinds of light. This light actually assists attention during the day but can result in interrupted sleep patterns at night.

    Scientists have also said that eyestrain is not a necessary evil, even in a modern world that revolves around technology. Changing some simple details about your relative position to screens, such as staying about 60 centimeters away, will help. Also, avoid overhead and other direct sources of light, and use shaded lamps and window blinds while looking at digital devices instead.

    Beyond the way that relates to digital screens, there are also ways to change how you view screens that are helpful in combating eyestrain. To begin with, your computer screen should be high-resolution(高清的), at least 50 centimeters wide diagonally and may require a screen filter to decrease reflections. Also, be aware that "computer glasses", which cut down glare and blue light, are available and those contact lenses can increase the risk of eyestrain.

    Besides, to reduce your risk for computer-vision syndrome and neck, back and shoulder pain, take frequent breaks during your computer workday. Many workers take only two 15-minute breaks from their computer throughout their day. According to a recent study, discomfort and eyestrain are significantly reduced when computer workers take four additional five-minute "mini-breaks" throughout their workday. And these additional breaks don't reduce the workers' productivity.

    Finally, many of us fall into bad habits while using digital screens that only worsen the effects of eyestrain. While viewing digital screens, many people blink one third less often than they usually do. Place a reminder on your computer to "blink" so that your eyes don't dry out. Also, rest your eyes' focusing muscles by using the 20-20-20 rule: Every 20 minutes, focus on something 20 feet away for 20 seconds.

(1)、What is Paragraph 2 mainlyabout?
A、The dangers of eyestrain. B、The causes of eyestrain. C、The symptoms of eyestrain. D、The effects of eyestrain.
(2)、Which of the following ways might not be helpful in relieving eyestrain?

(3)、It can be inferred from the passage that      .
A、overhead lights make the eyes less tired B、taking frequent breaks reduces eyestrain C、people tend to blink more often at a computer D、technology and eyestrain unavoidably go hand in hand
(4)、Which of the following shows the structure of the passage?
A、 B、 C、 D、
举一反三
根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

To be successful people

    Here are some opinions about successful and unsuccessful people.

    Make life plans and set goals

    You can't be successful without knowing where you are going. A life vision board, 10 years' plan and daily goals are useful tools of the successful people. {#blank#}1{#/blank#}

    If a diver surfaces too quickly, he may suffer the bends. Nitrogen (氮) dissolved (溶解) in his blood is suddenly liberated by the reduction of pressure. The consequence, if the bubbles (气泡) accumulate in a joint, is sharp pain and a bent body—thus the name. If the bubbles form in his lungs or his brain, the consequence can be death.

    Other air-breathing animals also suffer this decompression (减压) sickness if they surface too fast: whales, for example. And so, long ago, did ichthyosaurs. That these ancient sea animals got the bends can be seen from their bones. If bubbles of nitrogen form inside the bone they can cut off its blood supply. This kills the cells in the bone, and consequently weakens it, sometimes to the point of collapse. Fossil (化石) bones that have caved in on themselves are thus a sign that the animal once had the bends.

    Bruce Rothschild of the University of Kansas knew all this when he began a study of ichthyosaur bones to find out how widespread the problem was in the past. What he particularly wanted to investigate was how ichthyosaurs adapted to the problem of decompression over the 150 million years. To this end, he and his colleagues traveled the world's natural-history museums, looking at hundreds of ichthyosaurs from the Triassic period and from the later Jurassic and Cretaceous periods.

    When he started, he assumed that signs of the bends would be rarer in younger fossils, reflecting their gradual evolution of measures to deal with decompression. Instead, he was astonished to discover the opposite. More than 15% of Jurassic and Cretaceous ichthyosaurs had suffered the bends before they died, but not a single Triassic specimen (标本) showed evidence of that sort of injury.

    If ichthyosaurs did evolve an anti-decompression means, they clearly did so quickly—and, most strangely, they lost it afterwards. But that is not what Dr Rothschild thinks happened. He suspects it was evolution in other animals that caused the change.

    Whales that suffer the bends often do so because they have surfaced to escape a predator (捕食动物) such as a large shark. One of the features of Jurassic oceans was an abundance of large sharks and crocodiles, both of which were fond of ichthyosaur lunches. Triassic oceans, by contrast, were mercifully shark- and crocodile-free. In the Triassic, then, ichthyosaurs were top of the food chain. In the Jurassic and Cretaceous, they were prey (猎物) as well as predator—and often had to make a speedy exit as a result.

    “Long time no see” is a very interesting sentence. When I first read this sentence from an American friend's email, I laughed. I thought it was a perfect example of Chinglish.

    Obviously, it is a word-by-word literal translation of the Chinese greetings with a ruled English grammar and structure! Later on, my friend told me that it is a standard American greeting. I was too surprised to believe her. Her words could not convince me at all. So I did a research on google.com. To my surprise, there are over 60 thousand web pages containing “Long time no see.” This sentence has been widely used in emails, letters, newspapers, movies, books, or any other possible places. Though it is sort of informal, it is part of the language that Americans use daily. Ironically, if you type this phrase in Microsoft Word, the software will tell you that the grammar needs to be corrected.

    Nobody knows the origin of this Chinglish sentence. Some people believe that it came from Charlie Chan's movies. In the 1930s, Hollywood moviemakers successfully created a world wide famous Chinese detective named “Charlie Chan” on wide screens. Detective Chan likes to teach Americans some Chinese wisdom by quoting Confucius. “Long time no see” was his trademark. Soon after Charlie Chan, “Long time no see” became a popular phrase in the real world with thanks to the popularity of these movies.

    Some scholars refer to America as a huge pot of stew. All kinds of culture are mixed in the stew together, and they change the color and taste of each other. American Chinese, though a minority ethnic(少数民族的成员) group in the United States, is also contributing some changes to the stew! Language is usually the first thing to be influenced in the mixed stew.

    You can have some other examples than adoptions(采用)from Chinese, such as pizza from Italian, susi from Japanese, and déjà vu from French etc. There is a long list! Americans do not just simply borrow something from others. They will modify it and make it their own, so you would not be surprised to find a tofu and peanut butter hamburger in a restaurant, or to buy a bottle of iced Chinese green tea with honey in a grocery store. Since Americans appreciate Chinese culture more and more nowadays, I believe more Chinese words will become American English in the future. In this way the American stew keeps adding richness and flavor.

    Food is extremely important to us human beings and rice is one of the main food in the world. Australian researchers have discovered a way to genetically engineer rice which would provide significant health benefits to more than half the world's population.

    A study undertaken at the University of Tasmania, published in a respected journal of the National Academy of Sciences, discovered a method to increase the resistant starch (抗性淀粉)content in rice, making it more digestible and leading to lower rate of diabetes (糖尿病)and overweight.

    Steven Smith, the lead author of the study and a foreign expert for the Chinese government who has been appointed to work on crop improvement projects by the Chinese Academy of Sciences, said increasing the higher resistant starch content gave this “designer” rice many added health benefits. “We have discovered that we can increase the amount of resistant starch in cooked rice, which could provide health benefits for a large number of people in Asia and beyond,” Smith said in a media release on Friday. “The same approach can be adapted for use in other cereals, including wheat. Not only can it have benefits for diabetes and obesity, but also for disorders of the bowel(肠)including cancer.”

    Rice is the main food for more than half the world's population, providing much of the world with most of their calories. Smith said that as the rate of diabetes and obesity in Asian countries continued to grow, his “designer” rice could provide a way to limit health problems.

    “Not only does resistant starch reduce the possibility of a 'sugar hit' but it also reduces the appetite and promotes the growth of the healthy germs.” Smith said.

Smith divides his time between the University of Tasmania and his research lab in Beijing where he hopes to make significant advance in sustainable (可持续的)living.

    Your next car could have two seats, three wheels—two in front and one in the back and a top speed of more than 100 miles per hour. Elio Motors plans to make such a tiny car named the Elio. Its two seats sit front and back instead of side by side. The driver is positioned in the center with the passenger directly behind.

    The starting price for the car is just $6,800. It has only one door, on the left side, which cuts a few hundred dollars off the manufacturing costs. Having three wheels also makes it cheaper. It has air conditioning, power windows and door locks and an AM/FM radio. More features can be ordered through Elio's long list of suppliers. Elio will also sell the cars directly through its own stores and not through franchised dealers (特约经销商).

    Paul Elio dreamed as a kid that he would one day own a car company called Elio Motors. In 2008, tired of high gas prices, he started working on a car that burns gas in a more effective way. Equally important to him was creating US manufacturing jobs and making the car inexpensive enough to attract buyers who might otherwise be stuck in their old, unreliable cars. "Whatever matters to you, this can move the needle on it, he said.

    Already, more than 27,000 people have reserved one. Paul hopes to make 250,000 cars a year by 2020. So far, reservation holders are those who will use the Elio as a second or third car for work. Paul Elio believes the car will interest college students as well as used-car drivers who want something newer and more reliable, though.
