Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

    {#blank#}1{#/blank#} Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.

    For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷尔蒙). They speed the heart rate, raise blood pressure, or sugar into the blood, etc. {#blank#}2{#/blank#}

    Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep anger inside may face a greater danger of high blood pressure.

    {#blank#}3{#/blank#} They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “{#blank#}4{#/blank#} Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”

    Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. {#blank#}5{#/blank#}

A. In general the person feels excited and ready to act.

B. They said that laughter is much healthier than anger.

C. Expressing anger violently is more harmful than repressing it.

D. Anger may cause you a cancer.

E. Do not express your anger while angry.

F. Anger is a normal emotion that we all feel from time to time.

G. Doctors say the solution is learning how to deal with anger.

    Today, the world's diversity (多样性) of food crops is quickly decreasing. But scientists around the world are taking action. They are building seed banks. At seed banks, scientists store the seeds of many different crops.

    There are now 1,400 seed banks around the world. However, some banks are in warm countries. If the electricity fails, the seeds will get too hot and die. Other seed banks are in countries troubled by war. Sometimes people damage the seed banks. If this happens, valuable seeds can be lost forever!

    The organization Global Crop Diversity Trust decided they wanted to deal with this problem. So, they decided to build a global seed bank. This seed bank would contain a back-up, or extra copy, of all the world's seeds. Smaller seed banks would still collect and keep local seeds. But they would also send copies of their seeds to the global bank.

    Scientists from the Global Crop Diversity Trust chose the cold, snowy mountains of Svalbard, Norway to build the global seed bank — the Svalbard Global Seed Vault (斯瓦尔巴全球种子库). Organizations, farmers, or local seed banks store their extra seeds there. And the people who place their seeds in the vault are the only people who can take them out. They pay to ship their seeds to Norway, but it does not cost them any money to store their seeds. The Global Crop Diversity Trust pays for this.

    Cary Fowler is a scientist who heads the Global Crop Diversity Trust. He said, “If the Seed Vault simply supplies seed banks with copies of seeds that those banks lost by accident, the Seed Vault will be worth more than it cost.”

    Everyone can benefit a lot from reading books. The following is about various benefits of reading books.

    {#blank#}1{#/blank#} Whenever you read something, you learn information that you wouldn't have known. If you want to learn new words, reading books is a great way to enlargeyour vocabulary.

    {#blank#}2{#/blank#} Similar to solving puzzles, reading books allows your mind to practice its processing skills. Going without books for too long will turn your mind into mess.

    One of the primary benefits of reading books is its ability to develop your thinking skills. {#blank#}3{#/blank#} Wherever you are faced with a similar problem in real life, your mind is able to put its mystery solving skills to a test.

    The information in books can be referred to over and over again. For example, reading a cookbook allows you the chance to review the cooking steps whenever you need to. {#blank#}4{#/blank#} Don't even think about writing the information down because you may lose the paper sooner or later.

    These are just some of the wonderful benefits of reading books. {#blank#}5{#/blank#} If you can't even go outside, you can download free e­books online and read them on your computer. That way, you can see how useful reading can be for yourself.

A. You can improve your memory by reading.

B. Reading keeps your mind in good condition.

C. Reading books can make you become confident.

D. Reading books provides you with new knowledge.

E. Reading mystery novels, for example, trains your mind.

F. Following the steps from a cooking video will be difficult.

G. Why don't you drop into a bookstore and pick a book up?

    Another thing an astronaut has to learn about is eating in space．Food is weightless, just as men are.

    Food for space has to be packed in special ways．Some of it goes into tubes that a man can squeeze into his mouth．Bite-sized cookies are packed in plastic.

    There is a good reason for covering each bite．The plastic keeps pieces of food from traveling in the spaceship．On the earth very small pieces of food would simply fall to the floor．But gravity doesn't pull them to the floor when they are out of the plastic in a spaceship．They move here and there and can get into a man's eyes or into the spaceship's instruments．If any of the instruments is blocked, the astronauts may have trouble getting safely home.

    As astronauts travel on longer space trips, they must take time to sleep．An astronaut can fit himself to his seat with a kind of seat belt. Or, if he wants to, he can sleep in a sleeping bag which is fixed in place under his seat．But be careful he must put his hands under the belt when he goes to sleep．This is because he is really afraid that he might touch one of controls that isn't supposed to be touched until later.

    Houses have been getting progressively "smarter" for decades, but the next generation of smart homes may offer what two Case Western Reserve University scientists are calling an "Internet of Ears."

    Today's smart home features appliances, entertainment systems, security cameras and lighting, heating and cooling systems that are connected to each other and the Internet. They can be accessed and controlled remotely by computer or smartphone apps.

    But a group of electrical engineering and computer science professors in the Case School of Engineering have been experimenting with a new suite of sensors (传感器). This system would read not only the vibrations (震动), sounds and even other movements associated with people and animals in a building, but also any slight changes in the existing electrical field.

    While there still maybe a decade or so away, the home of the future could be a building that adjusts to your activity with only a few small, hidden sensors in the walls and floor with-out the need for monitoring cameras.

    "We are trying to make a building that is able t0 61isten' to the humans inside," said Ming-Chun Huang, an assistant professor in electrical engineering and computer science. "We are using principles similar to those of the human ear, where vibrations are picked up and our algorithms (计算程序) recognize them to determine your specific movements. That's why we call it the 61nternet of Ears'. "

    “There is actually a constant 60 Hz electrical field all around us, and because people are somewhat conductive, they short out the field just a little," Huang said. "So, by measuring the disturbance in that field, we are able to determine their presence, or even their breathing, even when there are no vibrations associated with sound.”

    Huang said they have used as few as four small sensors in the walls and floor of a room.

    As for privacy concerns, the system would not be able to identify individuals, although it could recognize people's different ways of walking.

    NAIROBI­Tin Tin, a Chinese restaurant located in central Nairobi, has been serving local Kenyans for nearly four decades with its delicious dishes and unique cultural background.

   "This is a restaurant definitely worth a try," said Steven, a local resident in his 30s. "It has provided Chinese food since my grandfather's time."

    According to Henry Tin, the restaurant owner, Tin Tin was established in 1978 at the heart of the Nairobi Central Business District, upholding Chinese cuisines while adapting to Kenyan preferences.

    For years, it has become a defining part of the city's landmark­Kenya International Conference Center­attracting lots of office workers nearby and even presidential customers.

   "The former president of Kenya, Moi, was a very good customer for us. He came almost always in cash. Then former president Mwai Kibaki and now president Uhuru. They all like to enjoy our food," Tin said.

    Danis, an office worker of an insurance company near the KICC says he is a frequenter of the restaurant.

   "It is the only Chinese restaurant in the highly competitive downtown area. Besides, its food has been adapted to our taste," Danis said, "My favorite dishes are fried shrimp and fried pork, which you can also find in a Kenyan restaurant."

   "High­quality food consistently served over the decades has helped maintain loyal customers," Enoch Kivunaga said, at Tin Tin.

   "My experience depends on the customers. If I cook good food, they always come back, whether they are presidents or ministers," he said.

    Tin said he speaks Swahili well and perfectly pronounces local names, which shows the Chinese culture and its Kenyan counterpart are quickly combining. "I am a Kenyan Chinese. I love both great countries."
