After decades of playing catch-up with the U.S. and Russian space programs, China did something neither nation nor any other had done this December: land a spaceship on the dark side of the moon.
Strictly speaking, of course, the moon has no dark side. But because of the way it orbits Earth, our natural satellite shows us only one side - the other is hidden from our view. No one even saw the far side until 1959, when the Soviet Luna 3 spaceship flew around for a look and sent back photos. No astronaut or spaceship went there until this December, when the China National Space Agency (CNSA) launched a 2,500-pound lander called Chang’e-4 to the southern end of the lunar far side.
Chang’e-4 operated a small rover (探测车) to survey the geography there for the first time ever. By examining the geography of its landing area, Chang’e-4 could solve longstanding puzzles about the moon, including how it formed 4.5 billion years ago. Chang’e-4 also carried a very small ―lunar biosphere (生态圈) ‖ containing silkworm eggs and a tiny greenhouse designed to grow potatoes in order to study the growth of the seeds on the moon.
Besides Chang’e-4, China plans to launch Chang’e-5 in 2019. Its mission will be to gather moon rocks using an orbiter, a lander or collector, an ascent stage (上升器) and a capsule that will separate from the orbiter and return the rocks to the earth. ―With these missions, the Chinese will have shown complete mastery of flight in the space between the earth and the moon,‖ said Paul Spudis, an experienced lunar researcher based in Houston.
CNSA has already outlined ideas for Chinese astronauts to follow the robots to the moon. Pei Zhaoyu, deputy director of CNSA’s Lunar Exploration and Space Program Center, told that China plans a permanent robotic lunar station in about 10 years and suggested a human presence on the moon another decade or so after that. Spudis said China’s ambitious Chang’e-4 and Chang’e-5 missions should send human’s plans for lunar return into rapid development.
1.What do we know about the dark side of the moon from the first two paragraphs?
A. Two western countries have taken its photos.
B. It is hidden from people’s view due to the earth’s orbit.
C. China is the first country to land a spaceship there.
D. It exists because the sun never shines there.
2.Why did Chang’e-4 operate a small rover?
A. To study the geography of the lunar dark side.
B. To grow potatoes on the moon.
C. To examine the growth of eggs and seeds.
D. To survey the lunar biosphere.
3.Which of the following can move apart from the orbiter of Chang’e-5?
A. The lander. B. The collector.
C. The ascent stage. D. The capsule.
4.What is Spudis’s attitude to China’s Chang’e-4 and Chang’e-5 missions?
A. Cautious. B. Disapproving.
C. Ambiguous. D. Favorable.

Over the past five decades mosquito populations in parts of the U.S. have skyrocketed by a factor of 10-a situation with worrying implications for the spread of diseases. And some places are apparently more easily affected than others. A new study in the Journal of Medical Entomology found that in Baltimore, low-income neighborhoods bear the biggest burden: they have not only more mosquitoes but also larger ones, which often survive longer. The problem most likely is rooted in the fact that Baltimore has nearly 17,000 abandoned buildings, which are concentrated in economically disadvantaged areas and serve as convenient mosquito-breeding zones.
Compared with prosperous blocks, low-income blocks have more abandoned buildings and are more heavily littered with thrown-away containers that collect standing water. And water that pools in abandoned buildings is protected by shade-which helps mosquitoes grow larger. Some cities take efforts to plant trees in low-income blocks but may actually worsen the problem: trees and bushes not only shade outdoor breeding(繁殖) pools but also shed leaves into the water and feed the mosquito larvae(幼虫), helping them grow bigger. Worse still, climate change could worsen the disease landscape by broadening habitats and lengthening the time every summer that mosquitoes can breed and survive.
Cities may, then, need to focus more mosquito-control efforts on these areas. Urban health departments typically educate homeowners about the importance of emptying water out of outdoor containers. But nobody empties those in or around abandoned buildings. “It is something that is fairly difficult for a city to address because it’s really expensive to go into private belongings and clean them up,” says Dina Fonseca, a molecular ecologist at Rutgers University. Yet if these belongings become breeding grounds not only for annoying mosquitoes but also for dangerous diseases, officials’ concepts may need to change.
1.What does the phrase “a factor of 10” in Paragraph 1 refer to?
A.A major cause. B.A high rate.
C.A big concern. D.A special situation.
2.Why is the spread of diseases relatively more serious in poor neighborhoods in Baltimore?
A.Because people there lack the awareness of waste sorting.
B.Because people there pay little attention to water protection.
C.Because more thrown-away containers are collected for reuse there.
D.Because more abandoned buildings serve as habitats for mosquitoes there.
3.Which of the following solutions is well-intentioned but may result in opposite effects?
A.Planting more trees. B.Changing officials’ ideas.
C.Emptying water containers. D.Cleaning abandoned buildings.
4.What is the author’s purpose in writing the text?
A.To complain about the poor housing. B.To offer some treatments for diseases.
C.To appeal for mosquito-control efforts. D.To introduce a new species of mosquitoes.

After nearly a decade of being in love with yoga, I made a courageous decision. I decided that I wanted to become a yoga teacher. Meanwhile, I made a list for those who will chase or are chasing a dream.
Remember that it’s meant to challenge you.
1.The only way that growth can occur within you is that you can find something that challenges you, and work through it. You may feel overwhelmed by challenge at some point, but the reward of achieving your dream is a way more fulfilling than never going after what you want to achieve at all.
Be careful who you ask for advice.
While chasing your dream, you will get to a point where you want to give up. You’ll question the cause of your dream and question whether you should continue.2.Find wisdom from those who are encouraging of your dream, and who understand what it means to you.
Believe in yourself.
The only way you’ll be able to follow through with your commitment to your dream is by believing that you can do it.3.However, their opinion only goes so far if you believe that you are capable. In addition, if you believe in yourself, when others doubt you, it isn’t worth being concerned about because you have found faith in yourself, and that’s all that matters.
4.
It takes a lot of courage to give everything that you have to achieve a goal when it might be criticized, judged or rejected. Many see failure as an ending, when it could be a beginning of another journey that leads to your dream.
Starting trying today.
In a year, you’ll wish you’d started today what you hope to achieve. If you don’t try today, how will you feel in a year? Time passes quicker than we can sometimes grasp, and today will eventually lead to the following year.5.
A.Be open to failure and rejection.
B.Yes, your dream needs to be big.
C.Others can tell you that you’re capable.
D.Everything begins in the heart and mind.
E.Don’t just sit around and think about what you want.
F.During this time, be cautious with where you seek advice.
G.Growth doesn’t happen by living in stability, comfort or at ease.

After the U.S. House of Representatives passed a bill aimed at retaliatory(报复的) action against China for its “significantly undervalued” currency, Treasury Secretary Timothy Geithner urged the IMF to pressure China to adopt “more flexible, more market-directed exchange-rate management”. This is a coded message to China: You’re keeping on purpose your currency cheap, and the U.S. economy is paying the price. So cut it out --- or else. The normally dull IMF meeting became the latest battleground for the U.S. to be against a fast developing China.
Our new conventional wisdom is that China’s policy leads to make trade deficits (逆差) greater and the loss of American jobs. Dozens of candidates have run ads attacking a competitor for allowing China to take advantage of us. In the election-year view, China grew 10% annually for the past decade while maintaining low inflation(通涨) only by taking advantage of its artificially low currency. The idea that the U.S. is not responsible for its own economy is a black-is-white view. It argues that China and its currency are causing the lion’s share of harm.
This is an argument born of fear. It covers a fact that the economies of China and the U.S. have become beneficial to each other. Those trillions in reserves that China accumulates: Where do they go? Back to the U.S. in the form of lending money to the federal government. Those made-in-China goods that account for the trade deficit: Whom do they benefit? China, yes, but also American consumers and companies. Without China, American companies could not have maintained their profitability in recent years. Take two brand names, Caterpillar and Nike. Both have their products made in China, but both also view China as a fast-growing market for their products.
George Soros warned recently that a currency war could put the world into disorder more damaging than anything caused by the financial crisis of the 1930s. He’s right. Whether we like it or not, we live in a global system. The zero-sum attitude toward China and its currency is a relic, the remaining of an earlier time when nations defined economic life.
China is far from perfect and seeks its own advantage, but holding it accountable for our domestic problems is beyond outdated. It reflects a dangerous refusal to deal with the world as it is. Retaliating against China over currency will not regain high-end jobs in the U.S., which needs more our own demand. It will not renew construction or retool the American labor force. It will not rebuild rotting bridges or create a next-generation energy network.
1.Which of the following argument can be supported by the writer?
A. China is the winner in the Sino-US trade.
B. China’s rapid development over the past ten years is based on its low inflation.
C. The world’s economy will benefit from China’s policy changes on its currency.
D. The US will get hurt if it tries hard on damaging China’s economy.
2.This passage is in a tone that is ____________.
A. in favor of China
B. in the shoes of US
C. blaming China’s low currency policy
D. helping IMF solve the world’s economic problem
3.The writer makes his point of view clear through the passage by using _____________.
A. reasonable analysis
B. leaders’ quotations
C. figure examples
D. moving stories
4.China’s currency policy ________.
A. will help increase the demand in the US
B. is unable to equip the American labor force with new working skills
C. could guide the world economy for the next decade
D. is to be controlled by the international currency groups
