    Cooking Kills Four Million People a Year

    Polluted airborne particles(大气悬浮颗粒)kill 7 million people a year, reports the World Health Organization.

    That news may not come as a surprise to anyone who has seen images of chimneys in Beijing, Delhi or Mexico. But those factories—or even the jammed roadways of modern cities—are not the biggest killer. Each year, some 4.3 million people die earlier than they should because of polluted air inside their homes, says the WHO.

    What’s causing the air inside people’s homes to be so poisonous that it kills around 11,000 people a day? Stoves. “Having an open fire in your kitchen is like burning 400 cigarettes an hour.” says Kirk Smith, a professor at the University of California at Berkeley, whose research suggests that household air pollution from cooking killed between 3.5 million and 4 million people in 2013.

    Not all stoves cause this kind of harm. The ones Smith’s talking about are those that the 3 billion people in the developing world use for heat and cooking, which burn solid fuels such as wood, coal, or crop waste instead of gas. The smoke from those fires produces harmful fine particles and carbon monoxide into homes. Poor ventilation then prevents that smoke from escaping, raising fine particle levels 100 times higher than the limits that the WHO considers acceptable.

    Breathing this air day in day out finally causes a lot of diseases: more than a third of the 4.3 million die of a stroke, while a quarter die of heart disease. And around one-third of annual lung disease deaths worldwide are due to waste from coal stoves.

    Exposure tends to be extremely harmful for the people who spend the most time around the fire—usually women and young children. In fact, the WHO reports that household air pollution almost doubles the risk for childhood lung disease.

    1. According to Kirk Smith’s research, ________.

    A. factories are the biggest killer worldwide nowadays

    B. burning 400 cigarettes an hour is extremely dangerous

    C. household air pollution from cooking is surprisingly harmful

    D. some 4.3 million people die earlier each year than they should

    2. What should be the deadly killer in a household kitchen?

    A. Solid fuels.       B. Coal stoves.         C. Poor gas.         D. Cooking smoke.

    3. The underlined word “ventilation” in Paragraph 4 probably means ________.

    A. airing           B. cooking             C. burning            D. cooling

    4. The author intends to tell people ________.

    A. how to avoid polluted air in their homes

    B. to stop cooking in the household kitchen

    C. to guard against household pollution from cooking

    D. how to prevent childhood lung diseases in household

       How much sleep is enough?

       To stay in good health, some expert in the US say, adults should get seven to eight hours of sleep. Teenager need nine to ten hours. And pre-school children need more than 10 hours of sleep a night.

       Experts say the quality(质量)of our sleep becomes poor as we grow older. This happens because the brain unit that controls sleep begins to weaken slowly as we age.

    Many people want to know how to help kids be fitter. There are some steps only parents can take, but kids can take charge, too. If you, a kid, want to be fit, the following may be useful.

    1. Eat a variety of foods, especially fruits and vegetables. You may have a favorite food, but the best choice is to eat a variety. In that case, you're more likely to get the nutrients your body needs. Shoot for at least five servings of fruits and vegetables a daytwo fruits and three vegetables.

    2. Drink water and milk most often. When you're really thirsty, cold water is the No. 1 thirst­quencher (饮料). And there's a reason your school cafeteria offers cartons of milk. Kids need calcium to grow strong bones, and milk is a great source of this mineral. Aim for 3 cups of milk per day, or its equivalent.

    3. Listen to your body. What does it feel like to be full? When eating, notice how your body feels and when your stomach feels comfortably full. Eating too much can make you feel uncomfortable and, over a period of time, can lead to unhealthy weight gain.

    4. Limit screen time. Screen time is the amount of time you spend watching TV or DVDs, playing video games, and using the computer. The longer you spend on these sitting­down activities, the less time available for active stuff, like basketball, and swimming. Try to spend no more than 2 hours a day on screen time.

    5. Be active. One job is to figure out which activities you like best. Not everyone loves baseball or soccer. Maybe your passion is kickball, or dancing. Ask your parents to help you do your favorite activities regularly. Find ways to be active every day.

    1Eating too much for some time will________.

    A. help you grow much taller

    B. make you feel energetic all the time

    C. make you put on much more weight

    D. make your bones grow strong

    2Which of the following is most probably taken charge of only by parents?

    A. Serving a balanced diet.

    B. Limiting screen time.

    C. Keeping an active life.

    D. Eating a variety of foods.

    3Which of the following is NOT true according to the text?

    A. If you don't eat a variety of foods, you may lack nutrients.

    B. Water and milk can help kids grow strong bones.

    C. Spending less than 2 hours a day before screen may not be harmful.

    D. All kids don't love baseball or soccer.

    4The text is mainly written for________.

    A. parents                                  B. teachers

    C. doctors                                  D. children

    阅读下列短文,从每题所给的四个选项(ABCD)中,选出最佳选项。

    According to Chinese medicine, the body is like a tree that lives through the seasons of nature, and it needs regular energy to stay healthy and prevent illness. The four important bodily organs need special energy in each season. We should eat special food and vegetables to protect them.

    The liver, which enriches the blood with energy and cleans the bad things in the body, is replenished in spring time. We'd better eat onions, carrots and some vegetable leaves.

    The heart seeks comfort and coolness from the heat in summer. Melons, pumpkins, cucumbers, tomatoes, and many fresh high­water vegetables have a cooling effect and should be eaten.

    The lungs often make people suffer from colds, coughs, and sore throats in the dry fall season. They need to be replenished with food such as spinach, bananas, pears, potatoes.

    The kidneys are the lowest organs in the body like the roots of a tree. They need protection in winter specially. Replenish the kidneys with vegetables like broccoli, green chard and some other green vegetables.

    We spend about one-third of our lives asleep. This may sound like a lot of timebut it is not wasted. Our bodies need sleep to stay healthy. Not getting enough sleep can make us sick.

    Sleep and our immune(免疫)system

    The immune system protects the body from diseases and infections(传染). Not getting enough sleep hurts this protective system.

    The Mayo Clinic is a research hospital in the United States. Its website explains that when we sleep our bodies produce proteins(蛋白质) that support sleep and help us fight infections. They add that infection-fighting antibodies(抗体) are reduced during periods when you don’t get enough sleep.

    A new study from the University of Washington in the U.S. seems to confirm this. Dr. Nathaniel Watson was the lead writer of the study. Watson says his study shows that the immune system works best when the body gets enough sleep. For the studyWatson and his team studied 11 pairs of twins. This is an important difference from other sleep studies. Other research did not study twins. Researchers found that the twin who slept less had a weaker immune system.

    Watson says his study showed for the first time that a long-term lack(缺乏) of sleep shuts down parts of the immune system. He says parts that move white blood cells around the body are influenced. White blood cells fight infections in the body.

    Watson’s study provides more evidence(证据) that sleep is important tooverall health. And sleep is especially important to immune health.

    The researchers published their findings in the magazine Sleep.

    How much sleep is enough?

    To stay in good healthexperts at the Mayo Clinic say that adults should get 7 to 8 hours of sleep. Teenagers need 9 to 10 hours. And school-aged children may need more than 10 hours of sleep a night.

    Experts say our sleep becomes poor in our 30s. By the time we reach our 50sthe average person has lost 50 percent of their ability to have a restful sleep. These people also have trouble falling asleep and staying asleep through the night. From middle age onthey say these problems only get worseand they can influence our health.

    Signs you may not be getting enough sleep

    You’re always hungry or you’ve gained weight.

    You have trouble making decisions.

    You have trouble remembering things.

    Your skin doesn’t look good.

    You are having trouble seeing.

    1. From the first three paragraphs we know that        .

    A. it is a waste to spend about one-third of our lives asleep

    B. we’ll become seriously ill if we don’t have enough sleep

    C. enough sleep does good to infection-fighting antibodies

    D. immune system is protected when people begin to sleep

    2. From Watson’s studywe know        .

    A. enough sleep helps the immune system work well

    B. the study of twins is a kind of common sleep study

    C. twins need less sleep but have stronger immune system

    D. sleeping for a long time is important to immune health

    3. Which of the following is right according to the passage?

    About ten men in every hundred have the trouble of color blindness in some way. Women are luckier, only about one in two hundred is affected(感染) in this matter. Perhaps, after all, it is safer to be driven by a woman.

    There are different kinds of color blindness. For example, a man cannot see deep red. He may think that red, orange and yellow are all shades(阴影) of green. Sometimes a person can’t tell the difference between blue and green. Only a few unlucky men may see everything in shades of green—a strange world indeed.

    Color blindness in human beings is a difficult thing to explain. In only one eye there are millions of very small things called “cones(圆锥体)”. These help us to see in the bright light and to tell differences between colors. There are also millions of “rods(柱状体)”, but these are used for seeing when it is nearly dark. They show us shapes but not colors.

    Some insects have favorite colors. Mosquitoes(蚊子) like blue but do not like yellow. A red light will not attract insects, but a blue light will. Human beings also have favorite colors. Yet we are lucky. With the help of the cones in our eyes, we can see many beautiful colors by day, and with the help of the rods we can see shapes at night.

    1. “Color blindness” means “_________” in Chinese.

        A. 盲目    B. 无色        C. 色盲      D.讨厌颜色

    2. Some people say it’s safer to be driven by women because _______.

      A. women drive more carefully                B. women are better at driving than men

        C. women can see things more clearly      D. there are fewer color-blind women

    3. With the help of the “cones”, we can __________.

        A. tell different shapes       B. kill insects

        C. see in the dark           D. tell orange from yellow

    4. ________ show us shape at night.

        A. rods     B. insects       C. cones      D. mosquitoes

    阅读下列短文,并做每篇后面的题目,从各题ABCD中选出能回答所提问题或完成所给句子的最佳答案

     “Life is speeding up. Everyone is becoming unwell.” This may sound like something someone would say today. But in fact, an unwell person who lived in Rome in AD 53 wrote it.

      We all love new inventions. They are exciting, amazing and can even change our lives.

      But have all these developments really improved the quality of our lives?

      Picture this: You’re rushing to finish your homework on the computer. Your mobile phone rings, a QQ message from your friend appears on the screen, the noise from the telephone is getting louder and louder. Suddenly the computer goes blank and you lose all your work. Now you have to stay up all night to get it done.

      Inventions have speeded up our lives so much that they often leave us feeling stressed and tired. Why do you think people who live far away from noisy cities, who have no telephones, no cars, not even any electricity often seem to be happier? Perhaps that is because they live simpler lives.

      One family in the UK went “back in time” to see what life was like without all the inventions we have today. The grandparents, with their daughter, and grandsons, Benjamin, 10, and Thomas, 7, spent nine weeks in a 1940s house. They had no washing machine, microwave, computer or mobile phone.

      The grandmother, Lyn, said, “The more things you have, the more difficult life becomes.” The boys said they fought less. Probably, they said, because there was less to fight over, such as their computer. Benjamin also noticed that his grandmother had changed from being a trendy, been-drinking granny, to one who cooked things.

    1. The writer uses the quote(引语) at the beginning of the story to____________.

    A. tell us the truth about life

    B. tell us what life was like a long time ago

    C. point out what causes such a thing to happen

    D. point out that you experience some big problems and they may be the same

    A. have stopped our lives

    B. have improved the quality of our lives

    C. may make people feel very happy

    D. may bring some people trouble

    3. The family chose to spend some time in a 1940s house because______________.

    A. they loved to live simple lives

    B. they wanted to know how people lived without modern inventions

    C. they were troubled by modern inventions

    D. living in a different time would be a lot of fun for them

    4. The passage is mainly about ____________.

    A. problems with technology

    B. improvements in our lives caused by technology

    C. changes happening to technology

    D. the importance of technology

    Seeing is believing(相信),but if our eyes don’t work, how can we see to believe?

    Today more and more kids wear glasses before going to middle school. Because they spend too much time watching TV or playing computer games without a rest. But we must do something to protect(保护)our eyes because they are important for us to see the world.

    Love your eyes. Every day , when we open our eyes, we can see the lovely friends and parents, beautiful flowers and green trees. Without them, there is only darkness. It is like a house without any light. How important our eyes are!

    Remember to rest your eyes. When you use the computer for an hour or two, it is time to stop to have a 30-minute rest. At school, you need to do eye exercises. Closing your eyes for resting is helpful, as well as looking at green trees or grass. In these ways, your eyes will feel relaxed.

    Have good habits. When writing homework and reading, it is important to keep a distance of 30 cm between your eyes and books. We should never rub(摩擦)our eyes with dirty fingers. Before and after swimming, use eye drops. Eat something healthy for eyes, such as carrots, fish and eggs.

    Aseeing is believing            BWe have to wear glasses
