    "Earworms", some people call them. Songs that get stuck in your head go round and round, sometimes for days, sometimes for months. For no clear reason you cannot help yourself from humming or singing a tune by Lady Gaga.
    To a psychologist, the most interesting thing about earworms is that they show a part of our mind that is clearly outside of our control. Earworms arrive without permission and refuse to leave when we tell them to. They are parasites (寄生虫) living in a part of our minds.
    If you have got an earworm you can suffer an attack of it simply by someone mentioning the tune, without having to hear it. This proves that earworms are a part of long-term memory. Humans have an "inner ear", for remembering phone numbers, for instance. When it gets infected with earworms, rather than review our plans for the day, or lists of things to remember, the inner ear gets stuck on a few short bars of music or a couple of phrases from a song. A part of us that we normally do not have to think about, that should just do what we ask, has been turned against us, upsetting us with a request that we never asked for. The mind is an inner world which we do not have complete knowledge of, or have control over.
    Fortunately psychology can provide some advice on how to deal with an uncontrollable mind. Consider the famous "don’t think of a white bear" problem, which tells you to try not to think about white bears, or to do something else, to avoid both thinking of the white bear and not thinking of the white bear. For earworms, the solution may be the same. Our inner ear has become infected with an earworm. This is a part not under our control, so just sending in instructions to "shut up" is unlikely to be of much help (and has been shown to make it worse). Much better is to employ the inner ear in another task. If your mind is poisoned by Brittany Spears’ Toxic, for instance, then try singing Kylie Minogue’s Can’t Get You out Of My Head. Let me know if it works!
    小题1:According to the passage, earworms are ______.
    A．songs that keep going round in our mind
    B．worms that live in a part of our brain
    C．tunes by pop singers like Lady Gaga
    D．parasites clearly under our control
    小题2:Which of the following statements is TRUE?
    A．Singing songs may get earworms out of your head.
    B．Earworms are used for keeping long-term memory.
    C．Humans do not have complete control over their mind.
    D．You won’t suffer from earworms unless you hear the song.
    小题3:What does “it” in the last paragraph refer to?
    A．The instruction to shut up your mind.
    B．“Don’t think of the white bear” problem.
    C．Kylie Minogue’s Can’t Get You out Of My Head.
    D．Using the earworm-infected inner ear in another task.
    小题4:What is the passage mainly about?
    A．The causes and influences of earworms.
    B．What earworms are and how to deal with them.
    C．How to clear earworms out of your head.
    D．The relation between earworms and popular songs.

    If you want to be a better reader，what should you know about the speed(速度)of reading? Some people read very quickly，when others read very slowly. But which one is better? The quick reader may be a good reader when he reads a story-book for fun. But he may not be able to slow down to read instructions(说明书) carefully. The slow reader may be a good reader. But he may spend too much time reading a story for fun. So the reader who reads everything quickly or the one who reads everything slowly isn’t really a good reader. Here are four things to remember about the speed of reading.
    Knowing why you are reading will help you to know whether(是否) to read quickly or slowly.

    Some things should be read quickly throughout. Examples are stories for enjoyment，letters from friends，and some news from newspapers.
    In some of your reading，you must change your speed from fast to slow and slow to fast. You will need to read some pages quickly and then slow down and do more careful reading when you come to important ideas.

    Do you have a mobile phone? Do you often send text messages（短信） to your friends or family? If you keep sending text messages over and over again, there may be something wrong with your fingers.  小题1: If you don’t, you may get injured one day.

    If you go to a fast food restaurant, you will probably see a lot of teenagers. Today, many teenagers are overweight, and this is because of their bad eating habits. Most teenagers are fond of food with a lot of fat, oil, salt and sugar. People call this kind of food “junk food”.
    But bad eating habits go beyond fast food. We find many teenagers eat unhealthily. Some don’t have breakfast before they go to school. During the day, some don’t have a proper meal for lunch. In a recent survey at one school, scientists found that over two thirds of the students didn’t follow a healthy diet. They didn’t like vegetables, and many of them didn’t like to eat fruits. They preferred to eat food with a lot of salt, sugar, or fat.
    Parents today also worry about their children’s diet. Some doctors give the following advice:
    Teenagers shouldn’t eat too much junk food.
    Teenagers shouldn’t eat food with too much salt. Salt can cause high blood pressure in the future.
    Teenagers should eat food without much fat, oil and sugar.
    Teenagers need to eat some fruits and vegetables every day. Fruits and vegetables are rich in vitamins（维生素）and have little fat.
    Teenagers need to drink more milk. Milk will help their bones grow.
    Teenagers need to eat breakfast every day. It is good for their body and mind.
    小题1:How many pieces of advice are given by the doctors in the passage?
    A．FiveB．EightC．SixD．Seven
    小题2: Which of the following is RIGHT?
    A．Today all teenagers are overweight.
    B．Scientists found two thirds of the students didn’t have a healthy diet.
    C．Parents are worried about their children’s diet today.
    D．Milk, fruits and vegetables are not good for children.
    小题3: It’s right to ___________ according to the passage.
    A．eat junk foodB．eat food with too much salt
    C．drink milk and eat junk food often D．eat vegetables that are rich in vitamins
    小题4:The main purpose of the passage is to tell the children____________.
    A．how to keep a healthy dietB．to eat fruits and vegetables
    C．how to have a proper meal for lunchD．not to eat junk food

    Now I know that we black people are much more likely to have high blood pressure and diabetes (糖尿病) than white people. And they often lead to heart attacks and other untreated diseases. For example, black people are three to four times more likely than white people to have high blood pressure and twice as likely as the white population to die of a stroke (中风).
    New research has found out the surprisingly high levels of salt in many of black people’s favorite meals. I stopped putting extra salt in my food at the table long ago and I try to cut down on the salt. I use in cooking. The suggested daily level of salt for adults is 6 grams. It is easy to see that if you try not to eat too many processed (加工过的) foods and use salt in your cooking within the limit, you won’t reach more than the daily level.
    The research showed how much salt there is in some foods that we buy from restaurants and takeaways. An average salad with rice and peas has 6.2 grams of salt. This is more salt than you are supposed to eat for the whole day.
    A researcher talked about the importance of home cooking rather than take-outs. At home, he pointed out, not only can you hold control of the salt bottle, but also you can create tasty food which is low on salt. The researcher later provided curry goat and rice and peas. They were low on salt, but completely delicious.
    I do not suppose Jamaicans are going to stop buying takeaways soon. But if you suffer from high blood pressure, it is probably better not to buy them often.
    小题1:The underlined word “they” in Paragraph 1 refers to _______.
    A．white peopleB．black people
    C．untreated diseasesD．high blood pressure and diabetes
    小题2:What has the new research found out according to Paragraph 2?
    A．Black people take in too much salt.
    B．Black people’s meals are very special.
    C．Processed foods have too much salt in them.
    D．6 grams of salt per day is enough for an adult.
    小题3:What would the writer probably suggest black people do?
    A．Order no salad in a restaurant.B．Take in no salt for several days.
    C．Stop cooking their favorite meals.D．Eat less takeaways.
    小题4:The researcher provided curry goat and rice and peas in order to _______.
    A．thank those who came to his home for his research
    B．let people know that eating less salt makes one healthier
    C．show that tasty food with less salt can be made at home
    D．prove the less salt the food has the more delicious it is
    小题5:What would be the best title for this passage?
    A．Watch the saltB．Take care, black people
    C．Say no to takeawaysD．Say no to high blood pressure

    How many things can you see in the night sky? A lot! On a clear night you can see the moon, some planets, and thousands of sparking stars.
    You can see even more with a telescope. You might see that many stars look larger than others. You might see that some stars that look white are really red or blue. With bigger and bigger telescopes you can see more and more objects in the sky. And you can see those objects in more and more detail.
    But scientists believe there are some things in the sky that we will never see. We won’t see them with the biggest telescope in the world, on the clearest night of the year.That’s because they’re invisible. They’re the mysterious dead stars called black holes.
    You might find it hard to imagine that stars die. After all, our sun is a star. Year after year we see it up in the sky, burning brightly and giving us heat and light. The Sun certainly doesn’t seem to be getting old or weak. But stars do burn out and die after billions of years.
    As a star’s gases burn, they give off light and heat. But when the gases run out, the star stops burning and begins to die.
    So next time you look up at the night sky, remember: there’s more in the sky than we can see!
    小题1:On a clear night we might see things except______.
    A．the moonB．some planetsC．sparkling starsD．the sun
    小题2:How can we see even more in the sky?
    A．By using a telescope
    B．By using a microscope
    C．By climbing up to the top of a mountain
    D．By going outside on a clear night.
    小题3:What does the underlined word”invisible”mean in Chinese?
    A．看不见的B．听不见的C．摸不着的D．无形的
    小题4:When a star’s gases_______,the star begins to die.
    A．burnB．run outC．give off heatD．get weak
    小题5:Which of the following is NOT TRUE according to the passage?
    A．We might see that many stars look larger than others with a telescope
    B．We might see that some stars that look white are really red and blue with a telescope.
    C．We can see some objects in more and more detail with bigger and bigger telescopes.
    D．The sun certainly seems to be getting old and weak.
