    A cellphone is one of the few things that we hold close to our faces all the time, and yet it could possibly explode - this is what made the recent Samsung's Galaxy Note 7 smart-phone accidents so shocking.

   According to technology news website The Verge, flawed(有瑕疵的)phone batteries might be to blame.

    Even if you are not a science student, you probably know that it is common sense that the anode (the negative(负的)end of the battery) and the cathode (the positive end) should never touch. If they do, the battery will short-circuit(短路), causing a powerful electrical reaction that can destroy the battery and cause a fire.

    This is why all lithium-ion(锂离子)batteries - the kind that can be found in many of our devices like tablets and cameras - have a separator layer inside to stop the two ends from touching one another.

    But somehow, the separators in some of the Samsung phones broke, causing explosions.

    Overcharging is another problem that can make batteries heat up quickly. Fortunately, most batteries are designed to be able to automatically stop charging once they are fully charged. But again, this somehow failed to happen in some of the Samsung phones.

    The two “somehows” may sound random(随机的)and hard to explain. But they actually both come from the fact that phone producers have been pushing the limits of batteries to meet customers' demand for a longer battery life.

    According to Lynden Archer, a materials scientist at Cornell University, US, we have already achieved 90 percent of the battery life possible from a lithium-ion battery. Customers' demand that their devices get thinner has also given producers little choice but to try to put more power into thinner batteries.

     “The more energy you put into a box, the more dangerous it's going to be,” Billy Wu, a lecturer at Imperial College London, told The Guardian.

    A thinner battery also means producers have to use thinner material for separators, and thinner material has more chance of breaking.

(1)、A separator layer is put in lithium-ion batteries in order to ___________.
A、ensure a longer battery life B、prevent a battery from short circuiting C、connect the anode and the cathode D、reduce a certain electrical reaction
(2)、What are the direct reasons for the Samsung phone explosions?
A、Short circuiting and overheating B、Pushing the limits of batteries C、Overcharging and thinner batteries D、Automatic charging and broken separators
(3)、Lynden Archer's comments indicate that ___________.
A、demands for thinner cellphones are unreasonable B、lithium-ion batteries can't hold much more power than that they do now C、producers can use 10 percent of a lithium-ion battery D、new material for batteries is needed to meet consumers' demands
(4)、What is the writer's main purpose of writing the article?
A、To describe problems facing cellphone producers B、To explain the reasons for the Samsung phone explosions C、To teach us common sense when it comes to batteries D、To warn us about the dangers of lithium-ion batteries

    Whether rich or poor, parents who have books in the home increase the level of education their children will attain, according to a 20-year study led by Mariah Evans.

    For years, educators have thought the strongest predictor of attaining high levels of education was having parents who were highly educated. But, the study showed that the difference between being raised in a bookless home compared to being raised in a home with a 500-book library has as great an effect on the level of education a child will attain as the difference between having parents who are barely literate (有文化的) and having parents who have a university education.

    Being a sociologist, Evans was particularly interested to find that children of lesser-educated parents benefit the most from having books in the home. What kinds of investments should we make to help these kids get ahead? The results of this study indicate that getting some books into their homes is an inexpensive way that we can help these children succeed. Evans said, "Even a little bit goes a long way. Having as few as 20 books in the home still has a significant impact on motivating a child to a higher level of education, and the more books you add, the greater benefit the children get.”

    The researchers were struck by the strong effect having books in the home had on children's educational attainment even above and beyond such factors as education level of the parents, the father's occupation or the economic level of the country.

    Having books in the home is twice as important as the father's education level, and more important than whether a child was brought up in a developing country or a developed country. Surprisingly, the difference in educational attainment for children born in developed country and children born in developing country was just 2 years, less than two-thirds of the effect that having 500 or more books in the home had on children.

    Computer technology is still developing rapidly. The computer of the future will continue to increase in value and performance while decreasing in cost. It will become smaller, but faster and more powerful.

    It is possible to make some guesses about what the future of the computer will look like, based upon the types of technologies that are being developed now. A lot of progress has already been made in some of these new technologies, but some are still in their earliest stages and may not be ready for use for years. Two of the most interesting areas of computing that are currently being developed are quantum computing (量子计算) and nanotechnology (纳米技术).

    Quantum computing is one possibility for the future of the computer that could make computers run far faster than even the quickest computers do today. Quantum computers could be able to do what modern supercomputers are unable to do by using transistors that are able to take on many states at the same time.

    Nanotechnology could also change the face of computing, by creating computers that could be very powerful, though they are tiny in size. These computers could be incorporated (并入) into everyday objects, including electrical appliances (电器), clothes and even the human body. We will be able to use computers in new and unimaginable ways. They will become a part of our lives rather than simply being a box that is used only for specific purposes, such as work.

    Quantum computing and nanotechnology will be able to play new roles, which will make us live greener lives, as well as enjoy better health and happier lives.

    Four days after Dad's 67th birthday, he had a heart attack. Luckily, he survived. But something inside him had died. His enthusiasm for life was gone. He refused to follow doctor's orders, and his sour attitude made everyone upset when they visit him. Dad was left alone.

    So I asked Dad to come to live with me on my small farm, hoping the fresh air would help him adjust. Within a week after he moved in, I regretted the invitation. He criticized everything I did. I became frustrated. Something had to be done.

    One day I read an article which said when given dogs, depressed patients would be better off. So I drove to the animal shelter that afternoon. As soon as I got there, a pointer's eyes caught my attention. They watched me calmly.

    A staff member said: “He got here two weeks ago and we've heard nothing. His time is up tomorrow.”

    I turned to the man in horror. “You mean you're going to kill him?”

    “Ma'am,” he said gently. “We don't have room for every unclaimed dog.”

    The staff member's calm brown eyes awaited my decision. “I'll take him,” I said.

    I drove home with the dog on the front seat beside me. I was helping it out of the car when Dad walked onto the front porch. “Look what I got you!” I said excitedly.

    Dad wrinkled his face. “I don't want it,” he muttered, turning back towards the house. Then, suddenly, the dog pulled free from my grasp. He sat down in front of my Dad.

    Dad's anger melted, and soon he was hugging the dog.

    This was the beginning of a warm friendship. Dad named the dog Cheyenne. Together they spent long hours walking down dusty lanes and relaxing on the banks of streams.

    Dad's bitterness faded, and he and Cheyenne went on to make many friends. Then, late one night two years later, I felt Cheyenne's cold nose burrowing(搜寻) through my bed covers. He had never before come into my bedroom at night. I ran into my father's room and found that he had passed away.

    Two days later, my shock and grief deepened when I discovered Cheyenne lying dead beside Dad's bed. As I buried him near their favorite stream, I silently thanked the dog for restoring Dad's peace of mind.

    The conclusion of the Paris Agreement in 2015, in which almost every nation committed to reduce their carbon emissions(排放), was supposed to be a turning point in the fight against climate change. But many countries have already fallen behind their goals. Meanwhile emissions worldwide continue to rise.

    The only way to catch up is to aggressively pursue an approach that takes advantage of every possible strategy to reduce emissions. Wind and solar energy are usually part of this effort, but it must also include investing heavily in carbon capture(碳捕捉), utilization(应用)and storage(CCUS)—a range of technologies that pull carbon dioxide from the air, and transform it into useful materials or store it underground. Although CCUS has been opposed as too expensive and unproved, recent gains have made it far more effective. Improvements such as chemical compounds could drive the cost down from $1 00 per ton of captured carbon in 20 16 to $ 20 per ton by 2025, according to a 2016 article in Science.

    Three primary CCUS paths lead to the reduction of carbon emissions: retrofitting(改装)existing power plants; reducing emissions in industries that cannot run on renewable energy; and directly removing carbon from the air. Cutting emissions from existing electric power stations with CCUS could be made more appealing in a future with a circular carbon economy, in which captured carbon could be resold and recycled for other uses——for instance, serving as a raw material for making concrete or plastics.

    The basic idea of carbon capture has faced a lot of opposition. Skepticism has come from climate change deniers, who see it as a waste of money, and from passionate supporters of climate action, who fear that it would be used to justify continued reliance on fossil fuels. Both groups are ignoring the recent advances and the opportunity they present. By limiting investment in decarbonization, the world will miss a major avenue for reducing emissions in a variety of industries. CCUS can also create jobs and profits from what was previously only a waste material by creating a larger economy around carbon.

    The transition to clean energy has become necessary. But that transition's ability to achieve deep decarbonization will become less effective without this wide range of solutions, which must include CCUS.

    Last year, on report card day, my son and a bunch of his 13-year-old friends piled into the back seat of my car, ready for the last-day-of-school party at McDonald's. "Jack got a laptop for getting straight A's, and Laurie got a cell phone," one boy said. "Oh, yeah, and Sarah got an iPod Nano, and she's only in third grade," said another. "And how about Brian? He got $10 for each A."

    I suddenly became concerned. These payoffs might get parents through grammar school, but what about high school and beyond? What would be left after the electric guitar, the cell phone, and the portable laptop?

    I saw the road ahead: As the homework load increased, my income would decrease. I saw my comfortable lifestyle vanish before my eyes — no more of those $5 bags of already-peeled organic carrots. No more organic anything!

    I started to feel surprised and nervous. Would every goal attained by my two children fetch a reward? A high grade point average? A good class ranking? Would sports achievements be included in this reward system: soccer goals, touchdowns(橄榄球触地得分(, runs-batted-in(棒球打点得分(? What about orchestra(管弦乐团(? Would first chair pay more than second? I'd be penniless by eighth-grade graduation.

"We never paid anything for good grades," said my neighbor across the street, whose son was recently accepted at MIT. "He just did it on his own. Maybe once in a while we went out for pizza, but that's about it."

    Don't you just hate that? We're all running around looking for the latest electronic products, and she's spending a few dollars on pizza. She gets motivation; we get negotiation.
