 阅读下列短文, 从每题所给的四个选项(A、B、C、D)中, 选出最佳选项。

As far as we know batteries are playing an important role in our life. We couldn't live without batteries. Why so? Batteries provide power for anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri (MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.

" To provide enough power, we need certain methods with high energy density (密度)", said Jae Kwon, assistant professor of electrical and computer engineering at MU." The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries."

Kwo n and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro/ nanoelectromechanreal systems(M/NEMS). Although nuclear batteries can cause concerns, Kwon said, they are safe.

" People bear the word‘ nuclear' and think of something very dangerous," he said," However, nuclear power sources have already been safely powering a variety of devices, such as pace- makers, space satellites and underwater systems."

His new idea is not only in the battery's size, but also in its semiconductor(半导体). Kwon's battery uses a liquid semiconductor rather than a solid semiconductor.

" The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor, Kwo n said," By using a liquid semiconductor, we believe we can minimize that problem."

Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwo n is working to build and test the battery. In the future, they hope to increase the battery's power, shrink its size and try with various other materials. Kwo n said that battery could be thinner than the thickness of human hair.

(1)、According to paragraph 1 and 2, we can learn that ____.
A、batteries can only power small sensors B、the larger batteries are, the more power they can provide C、Jae Kwo n is working hard to improve chemical batteries D、certain methods with high energy density can provide power abundantly
(2)、Jae Kwo n gave examples in Paragraph 4____.
A、to introduce various energy sources B、to describe a nuclear- powered system C、to introduce nuclear batteries can be safely used D、to show chemical batteries are widely applied
(3)、Liquid semiconductor is used to ____.
A、get rid of the radioactive waste B、decline the damage to lattice structure C、test the power of nuclear batteries D、decrease the size of nuclear batteries
(4)、According to Jae Kwon, his nuclear battery ____.
A、could be extremely thin B、will soon replace the present ones has. C、uses a solid semiconductor D、passed the final test

    For centuries, elephants have played a big role in the world's economies, culture and religion. The African elephant used to be found all over Africa and the Asian elephant moved from Syria to China to Indonesia. Nowadays, elephants are found in small groups in the south of the Sahara Desert and scarcely in Southeast Asia, Sri Lanka and India.

    In the early twentieth century, there were close to ten million elephants, and now the elephant number is as low as 252,000 and expected to drop down to 160,000 by 2025. Between 2007 and 2014, the elephant population fell by at least 30%, or 144,000 elephants. As researchers have traveled over the African plains, they only spotted one herd of 36 elephants in an area like the size of Mexico. It is clear that these gentle mammals are disappearing right before our eyes.

    There are many reasons why the elephant population has been decreasing, one of which is their habitat. Humans are competing with elephants for living space, and as more and more humans clear the land that is being used by elephants, the elephants have less space. Elephant hunting or "poaching" has been a major factor for the disappearance of this species, and they are killed only for their valuable ivory tusks. Although the trade of tusks is illegal, it is still a common practice in many places.

    Often, all the local people living among elephants would be farmers, and found that they could make more money by selling the tusks of one elephant, than doing manual labor for twelve years. That alone makes it really hard to prevent them from killing the elephants.

    Some places such as Botswana, have put in extra effort to protect their wildlife from poachers by founding their Botswana Defense Force, which is made up of around 700 specially-trained soldiers that are stationed in 40 different areas. You may feel worried about the present situations elephants are in, but there are ways to help. To find out how you can help elephant conservation, adopt an elephant, or donate, click here.

    The death of the plastic credit card could be a step closer as high street names including McDonald's and the Co-op prepare to test a breakthrough finger-scanning payment technology.

    FingoPay, developed by British start-up Sthaler, uses a biometric reader to scan the veins of a shopper's finger, building up a “map” that is unique to each individual.

    By connecting this pattern with a credit card or bank account, the company plans to let shoppers pay simply by placing their finger in a pocket-sized scanner, doing away with cash and credit cards.

    Sthaler, founded by former music industry executive Nick Dryden, will begin testing the technology next month in Proud, a London nightclub. Mr. Dryden said McDonald's is experimenting with a pilot of the technology, and that Sthaler is also planning a project with Co-op's food stores.

    It comes amid growing interest in using biometric identification in payments, which backers believe are more secure and efficient than passwords and PINs. Apple Pay, which uses the iPhone's fingerprint technology, launched in the UK in 2015 and was followed by the Android equivalent in May 2016.

    Hendrik Kleinsmiede, the director of Visa Europe's innovation arm Collab, which is backing Sthaler, said the Fingopay technology was less immune to problems such as wet and dusty fingers or fraud. “People are ready to accept biometrics as a secure authentication mechanism,” he said.

    Sthaler says the chance that two people have the same vein structure is 3.4bn-to-one, making it virtually impossible to crack. The vein scanner, developed by Hitachi, is already being used by Barclays to identify business customers as well as in cash machines in Japan, but Sthaler has the unique rights to license it to retailers.

    In the trial at Proud set to begin in September, the technology will be used to speed up waiting times at the bar both by cutting down on cards and by being able to suggest drinks based on what a patron has previously ordered.

    Two of the saddest words in the English language are "if only". I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.

    My father is famous in our family for saying, "Take the extra minute to do it right." I always try to live by the "extra minute" rule. When my children were young and likely to cause accidents, I always thought about what I could do to avoid an "if only" moment, whether it was something minor like moving a cup full of hot coffee away from the edge of a counter, or something that required a little more work such as taping padding (衬垫) onto the sharp corners of a glass coffee table.

    I don't only avoid those "if only" moments when it comes to safety. It's equally important to avoid "if only" in our personal relationships. We all know people who lost a loved one and regretted that they had foregone an opportunity to say "I love you" or "I forgive you." When my father announced he was going to the eye doctor across from my office on Good Friday, I told him that it was a holiday for my company and I wouldn't be here. But then I thought about the fact that he's 84 years old and I realized that I shouldn't give up an opportunity to see him. I called him and told him I had decided to go to work on my day off after all.

    I know there will still be occasions when I have to say "if only" about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality. And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I'm doing the right thing. I'm buying myself peace of mind and that's the best kind of insurance for my emotional well-being.

Choose the one that fits best according to the information given in the passage you have just read.

    After some blood tests, Dr Stubs stood before me, a tall man, but short on personality and sporting a cold expression. You have systemic lupus, he said matter-of-factly. "Lupus," he continued, "is an auto-immune disease and …." I remember certain details but mostly I remember him talking about children. "Children are no harm. But childbirth would jumpstart additional symptoms that could be life threatening. You already have two kids anyway."

    As I got up to leave, shaken and drained, he said his parting words, "I would discourage any further research. There is no cure and nothing can prevent its progression."

    Still, I did research lupus and its symptoms tiredness and joint pain-were both consistent with what I was experiencing. And eventually some major organs could be affected, causing shutdown and possibly death.

    I studied and found out that echinacea had a record in making immune system stronger. I decided that along with the plant I would strengthen my mindset by immersing myself in my family with my one-year-old son and three-year-old daughter.

    After another visit, I decided never to go back to Dr. Stubs. How could one endure repeatedly hear desperately words coming from an emotionless mouth even though they were truth? The years passed. When I would feel tired and achy I pulled support from my children and their laughter.

    Finally, after eight years, I went to Dr. Kirstein who was recommended by a friend. She stood there holding my hand and looking into my eyes warmly.

    "So let's talk a little

    Instantly my defenses were down. Before I knew it, she had me running on and on about my children, my husband, my life and dreams. I told her about all the meaningful activities I was involved in, those things I might have never done without the disease.

    After several follow-up tests, and greater research into my family history, Dr. Kirsteincame to conclusive answer. I did not have systemic lupus. There must be something wrong with the initial tests 8 years before.

    I didn't know whether I should jump for joy or scream because I had been living the last eight years in fear of a fatal disease. But then I realized that I had been living every day, not so much in fear, but happiness Even day was a gift and I knew it.

    Antarctica has become one of the world's most popular tourist destinations. Since 1969, the average number of visitors to the continent has increased from several hundred to over 34,000 today. All activities in Antarctica are heavily supervised by the Antarctic treaty for environmental protection purposes and the industry is largely managed by the International Association of Antarctica Tour Operators (IAATO).

    The first expedition (探险) to Antarctica with travelers was in 1966, led by Swedish explorer Lars Eric Lindblad. He wanted to give tourists first-hand experience of the ecological sensitivity of the Antarctic environment, in order to educate them and promote a greater understanding of the continent's role in the world. In 1969, Lindblad built the world's first expedition ship, the MS Lindblad Explorer, which was specifically designed to transport tourists to Antarctica.

    In 1977, both Australia and New Zealand started to offer scenic flights to Antarctica through Qantas and Air New Zealand. The flights often flew to the continent without landing and returned to the departure airport. The experience was an average 12 to 14 hours with up to 4 hours of flying directly over the continent. The flights from Australia and New Zealand stopped in 1980. It was largely due to the Air New Zealand Flight 901 accident on November 28, 1979. In 1994, flights to Antarctica continued again.

    Despite the potential dangers and risks, trips to Antarctica continued to grow. According to IAATO, 34,354 travelers visited the continent between 2012 and 2013. Americans contributed to the largest share with 10,677 visitors, or 31.1%, followed by Germans 11.1%, Australians 10.7%, and the British 10.2%. The rest of the visitors were from China, Canada, Switzerland, France and elsewhere.

    The cost of a trip to Antarctica can range from as little as $3,000-$4,000 to over $40,000, depending on the scope of transportation, housing, and activity needs. The higher end packages typically involve air transport, on-site camping, and a visit to the South Pole.
