Half of the world’s population is affected by Asian monsoons（季风）, but monsoons are difficult to predict. American researchers have put together a 700-year record of the rainy seasons, which is expected to provide guidance for experts making weather predictions.
Every year, moist （潮湿的）air masses，known as monsoon，produce large amounts of rainfall in India, East Asia, Northern Australia and East Africa. All this wet air is pulled in by a high pressure area over the Indian Ocean and a low pressure area to the south.
According to Edward Cook , a weather expert at Columbia University in New York., the complex nature of the climate systems across Asia makes monsoons hard to predict. In addition, climate records for the area are too recent and not detailed enough to be of much use. Therefore, he and a team of researchers spent more than fifteen years traveling across Asia, looking for trees old enough to provide long-term records. They measured the rings, or circles, inside thousands of ancient trees in more than 300 places.
Rainfall has a direct link to the growth and width of rings on some kinds of trees. The researchers developed a document they are calling a Monsoon Asia Drought Atlas. It shows the effect of monsoons over seven centuries, beginning in the 1300s.
Professor Cook says the tree-ring records show periods of wet and dry weather. “If the monsoon basically fails or is a very weak one, the trees affected by monsoons at that location might put on a very narrow ring. But if the monsoon is very strong, the trees affected by that monsoon might put on a wide ring for that year. So, the wide and narrow ring widths of the chronology that we developed in Asia provide us with a measure of monsoon variability.” With all this information, researchers say they can begin to improve computer climate models for predicting the behavior of monsoons.
“There has been widespread famine and starvation and human dying in the past in large droughts. And on the other hand, if the monsoon is particularly heavy, it can cause extensive flooding.” said Eugene Wahl, a scientist with America’s National Oceanic and Atmospheric Administration. “So, to get a sense of what the regional moisture patterns have been, dryness and wetness over such a long period of time in great detail, I would call it a kind of victory for climate science.”What’sthe passage mainly about？

One of my China Dialogue colleagues in Beijing recently bought a Philips energy-saving light bulb to replace a standard one．He was happy with his choice．It may have cost 30 yuan （just under US$4．50） - ten times the price of a filament （灯丝） bulb - but he wanted to save energy as part of his low-carbon lifestyle．And according to the shopkeeper, he would save, in the long run, much more than the 30 yuan he was spending．
Yet only one month later, his expensive light bulb blew up, before he had saved even a small part of the purchase price．Will he stick to his high-cost, low-carbon lifestyle?
China's environmental organizations have started to advocate low-carbon lifestyles and the decrease of carbon footprints to help fight against climate change．But they have overlooked one fact: in China, low-carbon living comes at a high cost．It means buying energy-saving bulbs and appliances, and environmentally friendly building materials and daily goods．Cost can no longer be the only standard for purchases．An energy-saving and environmentally friendly product is more expensive than a standard alternative - whether it's a simple light bulb or the house it shines．For average consumers, even buying an ordinary bulb is a huge burden．How can we persuade ordinary people to choose an energy-saving residence? This is not a trend they can afford to follow; perhaps this fashion is only for the rich．
Most consumers today do not cause huge carbon dioxide （CO2） emissions．Their responsibility lies not in choosing a low-carbon lifestyle today, but in avoiding a high-carbon life in the future．The principle of "common but differentiated responsibility" - a basis of sustainable development - can be applied here as well．
In China, low-carbon living still is resisted by a lack of social infrastructure（基础设施）. Even if your salary allows you to make that choice, nobody is there to help you accomplish it．
Consider energy-saving homes. You need to find out whether or not the developer has used natural materials wherever possible; how effective the insulation（绝缘物、隔热物） is; and what the green credentials of installed equipment are．You can read up a little, but you'll still be lucky to avoid being puzzled by the developers' marketing．Many so-called energy-saving buildings are nothing of the sort, and some are even more energy-hungry than the average home - as Li Taige warned in his article "Energy-efficient buildings? Not always", on China Dialogue last August．What may probably be the best title of this passage?
| A．To purchase a cheap bulb - your wise alternative． |
| B．To choose an energy-saving residence - a must of your life |
| C．To learn a low-carbon lifestyle - each citizen's responsibility |
| D．To learn a low-carbon lifestyle - a promising but difficult purpose |
Why does the writer say this fashion is only for the rich in the fourth paragraph?
| A．Because the cost is a very important standard for purchases. |
| B．Because buying an ordinary bulb is very expensive. |
| C．Because energy-saving products are more expensive than the common alternatives. |
| D．Because rich people like to follow this trend. |
What does the writer think of energy-saving homes?
| A．Most of them are environmentally friendly. |
| B．They are musts of low-carbon lifestyle of Chinese. |
| C．They are huge burdens for Chinese people. |
| D．Many of them are more in name than in reality. |
We can infer from the passage that ____．
| A．Using energy-saving bulbs and appliances is a fashion． |
| B．It's easy for most Chinese to try to learn a low-carbon lifestyle． |
| C．All citizens in China don’t have the same responsibility in living a low-carbon lifestyle． |
| D．Most Chinese families cannot afford to purchase an energy-saving residence. |
What is the writer's attitude towards the low-carbon lifestyle?
| A．informative and entertaining | B．supportive but cautious |
| C．negative but wise | D．positive and active |
Chinese and Nigerian media should pay more attention to their own growing roles and strive to present a reliable image of China to African audiences and vice versa(反之亦然). Agreement on this important step in ongoing cooperation between the two sides was reached by media representatives attending a media forum on September 19 in Abuja, Nigeria.
The agreement comes in the wake of increasing attention being paid by the international community on Africa's deepening relationship with China. "This presents an important opportunity for media in China, Nigeria and other African countries. We should seize the moment to expand cooperation between Chinese and Nigeria media, increase our say, and contribute to cooperation between China, Nigeria and Africa as a whole," said Li Wufeng, Vice Minister of the State Council Information Office at the China-Nigeria Media meeting.
The media meeting was jointly held by the State Council Information Office, the Chinese Embassy in Nigeria, and the Federal Ministry of Education, Nigeria. It formed part of the "Experience China" program, which aims to increase cultural exchanges and mutual understanding between China and other parts of the world.
In the past, due to poor communication facilities, China and African countries could only learn about each other through third parties, in particular Western media, which may have given rise to and perpetuated misunderstandings.
"China is still not a constant feature or subject on the front page and prime time in the news media in Nigeria unless there are disasters and alleged human rights abuses to be reported," said Martins Oloja, Editor of The Guardian.
Major Western media continue to promote a Cold War mentality and view Sino-African ties through the lens of geopolitics, framing everything as competition between East and West, Chinese and Nigerian media professionals said at the forum. Some Western media outlets accuse China of ignoring mutually beneficial solutions or sustainable development of African people, while robbing the continent of its natural resources.
"Nigerians cannot expect Aljazeera or BBC to report on Africa, and indeed Nigeria and China relations, the way we want," said Oloja.
Mutually objective coverage will generate more cooperation and better understanding between China and Nigeria, said Li Xiaohua, a representative from China. org.cn, a leading multi-language website in China.What is the purpose of this media forum on September 19 in Abuja?
| A．More international community should pay attention to Africa’s deepening relationship with China. |
| B．People should seize the moment to expand cooperation between China and African countries. |

It’s common for parents to feel emotional when the moment comes for their child to leave home and go to university. Even parents who don’t speak about the event are likely to feel a sense of sadness because it’s the end of an era where you and your family were at the centre of your child’s world. As a parent you’ll probably continue to support your child in different ways, but the main job of raising your child is over. It’s a huge change for everyone involved.
There are a few things that you can do to make the transition easier. Plan carefully for your child’s departure and think about how you can help. Many parents take their child to university for the first time. If you decide to do that, be ready to feel a real wrench when the time comes to say goodbye. Your child will probably be as nervous as you are about the moment when you finally say goodbye – but that might not show!
Be positive and cheerful about the choice your child has made to continue studying, and plan to leave once you’ve unpacked the car and looked around your child’s new living accommodations. If you can, save your tears for the car – you’ll make things easier on your child and yourself.
The more you’ve invested in being a parent, the more you’ll feel a sense of loss, so the sadness you feel now is a sign that you’ve been a good mom or dad. Remind yourself that parenting is all about raising an independent and confident child who functions well without you. If your child quickly settles and starts enjoying himself, you should congratulate yourself.
It’s also only fair to allow yourself some time to grieve. Don’t expect to pick yourself up and move on straight away. But you may decide to find a hobby or sport to fill your extra time. Perhaps you’ve always wanted to learn a new language, go to yoga classes or take up swimming. You may decide to spend more time with family and close friends, who are likely to be feeling the absence of your child as well.
Agree on the best approach to staying in touch before your child leaves, and stick to your agreement. Try not to panic if your child doesn’t respond immediately – remember, they’re starting a new and busy life.The underlined word “wrench” in Paragraph 2 means a feeling of ________.
| A．sorrow | B．regret | C．anger | D．love |
What does good parenting consist of?
| A．Supporting your child in different ways all the time. |
| B．Congratulating yourself when your child goes to college. |
| C．Preparing your child to stand on their own feet in the future. |
| D．Investing as much as possible in the growth of your child. |
What’s NOT advised as the way to recover from your child’s departure?
| A．Developing a new hobby or sport |
| B．Learning a new language. |
| C．Spending more time with close friends |
| D．Staying in touch with your child. |
What would be an appropriate title for the whole passage?
| A．Staying in Touch with Your Child |
| B．Preparing to Say Goodbye to Your Child |
| C．Dealing with Your Child Leaving Home for University |
| D．Life after Your Child Has Left Home for University |
Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises, according to scientists. They say that socializing and meeting with friends help increase levels of brown fat in the body which burns calories to produce heat.
Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult, normally requiring long-term stay in cold conditions or exciting part of the body's nervous system.
However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.
Study author, Dr Matthew During, whose team’s findings appear in the journal Cell Metabolism, said, “I'm still amazed at the degree of fat loss that occurs.” explaining how new technology had threatened face-to-face socializing, he added, “It's not just a sedentary(久坐的) lifestyle and high calorie foods, but an increasing lack of social activities.” Co-author Dr Lei Cao said，“Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital.”What information can we get from the first two paragraphs?
| A．Brown fat stores calories and makes us fatter. |
| B．It doesn’t take long to turn white fat into brown. |
| C．Social excitement helps gain more weight. |
| D．Brown fat can burn energy to produce heat. |

| A．Levels of brown fat can be increased by socializing. |
| B．The mice lacking social life lose more weight. |
| C．The research findings haven’t been published so far. |
| D．Dr Matthew During wasn’t convinced of the result. |
We can conclude from the text that_______.
| A．the fat in mice’s belly was reduced because of the relaxing environment |
| B．a sedentary lifestyle and high calories foods influence people’s social life |
| C．surfing the Internet may influence people’s face-to-face communication |
| D．cancer and death are mainly caused for lack of social life |
What’s the main idea of the text?
| A．Brown fat is beneficial to people’s health. |
| B．Socializing is unnecessarily important in people’s daily life. |
| C．White fat can be changed into brown fat. |
| D．Socializing contributes to people’s losing weight. |
As a senior, my future is always on my mind. To be exact, thoughts of the future have kept me up countless nights and made me worry enough to do poorly on more than one test. Because of this, words of wisdom are a source of comfort. Steve Jobs gave a speech to Stanford’s graduating class in 2005 and his words resound repeatedly in my mind whenever I think about my future.
It wasn’t always like that, though. It started when I became a junior, when college came into view. It’s the first big step to making your life your own. So when Jobs discussed his life as a student, some fears were eased. He, too, felt the need to attend college to make something of himself. He faced what many are extremely afraid of: uncertainty. His lack of understanding caused him to stop attending college and focus on what he felt was important. His story had a happy ending, of course, since he certainly turned out well.
This doesn’t mean that students shouldn’t attend college, but rather that they shouldn’t worry so much. You’ll get where you need to go, even if your path is a bit more winding than you’d like.
Jobs talked about the hardships in his work. His love of his work helped him carry on and he got where he was meant to be, which restates the point: don’t panic.
One particular part of his speech stayed with me. Steve Jobs quoted the saying “Stay hungry, stay foolish” and it has become my motto. Staying foolish is realizing that you are still a fool, no matter how much you’ve learned or experienced. There is always more to explore. Staying hungry is wanting to find those things about which you are still uneducated.
Steve Jobs’s level of success is attainable, and I aim to prove that. With the will power to go into the world living every day like it’s my last and allowing the future to take care of itself, I will do great things. In the last moments of my life, I’ll be proud of what I have done and hope to have all the wisdom a person could wish for.The author felt worried when _________.
| A．he had to take tests at school | B．he thought about his future |
| C．he had lots of sleepless nights | D．he searched for words of wisdom |
What did the author gain from Jobs’s speech?
| A．Courage to drop out of school. | B．Confidence in defeating Jobs. |
| C．Interest in computer industry. | D．Bravery to face uncertainties. |
What did NOT Steve Jobs encourage students to do in his speech?
| A．Have the desire to learn more. | B．Be content with what they know. |
| C．Stay calm in the face of hardships. | D．Be modest so as to learn more. |
