Everyone likes to have friends who are 1.(rely). When what we say matches what we do, we earn trust and friendship. Therefore, the2. (important) of keeping one's promise cannot be stressed too much.
There was a story of someone3. （break）his promise to his friend. Two men 4. were travelling through a forest together promised to help each other whatever danger threatened them. They had not gone far when a bear rushed at them from some bushes. One man was a good climber, and quickly climbed a nearby tree, but the other, seeing that he had no chance alone against the bear, fell flat 5.his back and pretended to be dead.
The Bear came up to him and sniffed at him. The Bear thought the man was dead, so he went off into the wood again without hurting him. When he had gone, the other traveler came down from his tree, and smilingly asked his companion what the Bear 6.(say) to him.“My 7.(good) friend, ” he said, “I saw the Bear put his mouth close to your ear. ” “He told me to tell you, ” replied the other8. (calm), “that you were 9.great coward, and that in future I should not trust those who make fine promises, but will not stand by their friends in danger. ”Don't trust fine promises 10. you are sure of the person who makes them.
As long as we have been on earth, we have used the sea around us. We take from the ocean, and we give to it.
We take fishes from the ocean — millions of kilograms of fish, every year, to feed millions of people. 1. We take minerals from the ocean. One way to get salt is to place seawater in a shallow basin and leave it until it evaporates(蒸发). 2. Much gold and silver drift dissolved in the waters of the sea, too. But the sea does not give them up by simple evaporation. Other gifts from the sea are pearls, sponges and seaweed. Pearls become jewelry. 3. Seaweed becomes food of many kinds— even candy, and ice cream — as well as medicine. Believe it or not, fresh water is another gift from the sea. We cannot drink ocean water. 4. But ocean water becomes fresh water when the salts are removed. In the future，we will find ourselves depending more and more on fresh water from the sea.
The sea gives us food, fertilizer, minerals, water, and other gifts. What do we give the sea? Garbage. 5. Huge as it is, the ocean cannot hold all the water that we pour into it. Dumping garbage into the ocean is killing off sea life2. Yet as the world population grows, we may need the sea and its gifts more than ever.
We are finally learning that if we destroy our seas, we might also destroy ourselves. Hopefully, it is not too late.
A. Natural sponges become cleaning aids.
B. We pollute the ocean when we use it as a garbage dump.
C. The area of the sea is becoming smaller and smaller.
D. Along with salt, other minerals are left after evaporation.
E. We even use their bones for fertilizer.
F. Some of its contents may cause illness.
G. We take a lot from the ocean and give little to the sea.
Coal burning deep underground in China，India and Indonesia is threatening the environment and human life, scientists have warned. These large-scale underground fires cause the ground temperature to heat up and kill surrounding vegetation, produce greenhouse gases and can even bring about forest fires, a panel（专门小组）of scientists told the annual meeting of the American Association for the Advancement of Science in Denver. They warned the resulting release of poisonous elements like arsenic （砷）and mercury（汞）can also pollute local water sources and soils “Coal fires are a global disaster,” said Associate Professor Glenn Stracher of East Georgia College in Swainsboro, U.S.A. But surprisingly few people know about them.
Coal can heat up on its own, and eventually catch fire and burn, if there is a continuous oxygen supply. The heat produced is not caused to disappear and under the right combinations of sunlight and oxygen, can trigger spontaneous（自然产生的）catching fire and burning. This can occur underground in coal stockpiles（煤堆）, abandoned mines or even as coal is transported. Such fires in China destroy up to 200 million tons of coal per year, delegates were told. In comparison, the U. S. economy consumes about one billion tons of coal annually, said Stracher, whose analysis of the likely effect of coal fires has been accepted for publication in the International journal of Coal Ecology. Once underway, coal fires can burn for decades, even centuries. In the process, they release large volumes of greenhouse gases, poisonous fumes and black particles into the atmosphere.
The members of the panel discussed the effect these fires may be having on global and regional climate change, and agreed that the underground nature of the fires makes them difficult to detect(发现). One of the members of the panel, Assistant Professor Paul Van Dijk of the International Institute for Geo-Information Science and Earth Observation in the Netherlands, has been working with the Chinese government to detect and monitor fires in the northern regions of the country.
The remote sensing and other techniques will allow scientists to estimate how much carbon dioxide these fires are emitting. One suggested method of controlling the fires was presented by Gary Colaizzi, of the engineering firm Goodson, which has developed a beat-resistant grout designed to be pumped into the coal fire to cut off the oxygen supply.

A.Coal heats up on its own and catches fire and burns.
B.The underground oxygen will be used up.
C.Poisonous fumes and greenhouse gases will be accumulated underground.
D.There will be an increase of abandoned mines.
2.What did Stracher analyze in his article published in the International Journal of Coal Ecology? ________.
A.Annual consumption of coal in US.
B.Annual consumption of coal in China.
C.How long coal fires have lasted in the northern region of China.
D.Coal fires may have an effect on the environment.
3.Which of the following statements about Paul Van Dijk is NOT true? ________.
A.He was one of the scientists who have warned against the threats of underground fires.
B.He has detected and monitored underground fires in the Netherlands.
C.He has worked with the Chinese government on the underground fires issue.
D.He works for a research institute in the Netherlands.
4.What is the suggested method to control underground fires in the passage? ________.
A.Using remote sensing technique.
B.Controlling the release of carbon dioxide.
C.Cutting off the oxygen supply.
D.Making the soil heat resistant.
On the 70th anniversary of the founding of the People's Republic of China, Chinese scientist Tu Youyou, winner of the 2015 Nobel Prize for the discovery of artemisinin, has been awarded China's Medal of the Republic. The medal is the country's highest honor for outstanding figures that have made great contributions to the construction and the development of the P.R.C.
Tu Youyou, born in 1930, has become the first Chinese woman to win a Nobel Prize, for her work in helping to create an anti-malaria medicine. The 84-year-old’s route to the honor has been anything but traditional. In China, she is being called the “three nos” winner: no medical degree, no doctorate, and she’s never worked overseas. In 1967, malaria, a then deadly disease, spread by mosquitoes was decimating Chinese soldiers fighting Americans in the jungles of northern Vietnam. A secret research unit “Mission 523” was formed to find a cure for the illness. Two years later, Tu Youyou was instructed to become the new head of “Mission 523”.
“Mission 523” read ancient books carefully for a long time to find historical methods of fighting malaria. When she started her search for an anti-malaria drug, more than 240,000 compounds(化合物)around the world had already been tested, without any success. Finally, the team found a brief reference to one substance, sweet wormwood(青蒿), which had been used to treat malaria in China around 400 A.D. The team took out one active compound in wormwood, and then tested it. But nothing was effective until Tu Youyou returned to the original ancient text. After another careful reading, she changed the drug recipe one final time, heating the compound without allowing it to reach boiling point.
After the drug showed promising results in mice and monkeys, Tu Youyou volunteered to be the first human recipient of the new drug. “In any case, Tu Youyou is consistently praised for her drive and passion”. One former colleague, Lianda Li, says Ms. Tu is “unsociable and quite straightforward”, adding that “if she disagrees with something, she will say it.”
Another colleague, Fuming Liao, who has worked with Tu Youyou for more than 40 years, describes her as a “tough and stubborn woman”. Stubborn enough to spend decades piecing together ancient texts, she applies them to modern scientific practices. The result has saved millions of lives.

3.Which of the following statements is true?
A.Tu first invented the idea of using sweet wormwood as a cure.
B.Tu was inspired by medical textbooks published in northern Vietnam.
C.The compound needs to be heated to the boiling point to be effective.
D.Over 240,000 compounds were proved ineffective before Tu’s search.
4.Tu Youyou can be best described as a person.
A.devoted and stubborn B.straightforward and mean
C.considerate and tough D.sociable and generous
Betty and Harold have been married for years .But one thing still puzzles (困扰) old Harold .How is it that he can leave Betty and her friend Joan sitting on the sofa ,talking ,go out to a ballgame ,come back three and a half hours later ,and they’re still sitting on the sofa ? Talking ?
What in the world ,Harold wonders ,do they have to talk about ?
Betty shrugs .Talk ? We’re friends .
Researching this matter called friendship ,psychologist Lillian Rubin spent two years interviewing more than two hundred women and men .No matter what their age ,their job ,their sex ,the results were completely clear :women have more friendships than men ,and the difference in the content and the quality of those friendships is “marked and unmistakable .”
More than two –thirds of the single men Rubin interviewed could not name a best friend. Those who could were likely to name a woman .Yet three-quarters of the single women had no problem naming a best friend ,and almost always it was a woman .More married men than women named their wife/husband as a best friend ,most trusted person ,or the one they would turn to in time of emotional distress （感情危机）.“Most women ,”says Rubin ,“identified （认定） at least one ,usually more ,trusted friends to whom they could turn in a troubled moment ,and they spoke openly about the importance of these relationships in their lives .”
“In general,”writes Rubin in her new book ,“women’s friendships with each other rest on shared emotions and support ,but men’s relationships are marked by shared activities.” For the most part ,Rubin says ,interactions （交往）between men are emotionally controlled –a good fit with the social requirements of “manly behavior .”
“Even when a man is said to be a best friend ,”Rubin writes ,“the two share little about their innermost feelings .Whereas a woman’s closest female friend might be the first to tell her to leave a failing marriage ,it wasn’t unusual to hear a man say he didn’t know his friend’s marriage was in serious trouble until he appeared one night asking if he could sleep on the sofa .”
