    English is very important in the modern world. Many people want to learn it well. Here are some things that I want to say about learning it.
    To learn English well, you need two things－passion and good learning methods (方法). Passion is the more important one. Why? Because passion makes you want to learn English. Learning methods only tell you how to learn it better and faster.
    If you love learning English, you will learn it regularly (有规律地) and spend much time on it.

    First, imagine that you can talk to native speakers just as you talk in your mother language. Imagine yourself to be a manager in a foreign company. Imagine you’re living in an English-speaking country.
    Second, use English as much as possible. This is very important. The more you use English, the better you’ll learn it. English is very popular, so you can use it everywhere. You can watch American cartoons, write English diaries, and read interesting books written in English.

    It was a village in India. The people were poor but they were happy. After all, their forefathers had lived in the same way for centuries.
    Then one day, some visitors from the city arrived. They told the villagers there were some people elsewhere who liked to eat frog. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other places.
    This seemed like money for nothing. There were millions of frogs in the fields around, and they were useless to the villagers. What they had to do was to catch them. Agreement was reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. The villagers were able to dream of a better future. But the dream didn’t last long.
    The change was hardly noticed at first, but it seemed as if the crops weren’t doing so well. More worry was that the children fell ill more often, and there were more insects around lately. The villagers decided that they couldn’t just wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides (杀剂) and medicine. Soon there was no money left.
    The people realized what was happening. It was the frog. They hadn’t been useless. They had been doing an important job--- eating insects. Now with so many frogs killed, the insects were increasing more rapidly. They were damaging the crops and spreading diseases.
    Now, the people are still poor. But in the evenings they sit in the village square and listen to sounds of insects and frogs. These sounds of the night now have a much deeper meaning.
    小题1:From Paragraph l, we learn that the villagers_______.
    A．worked very hard for centuries
    B．dreamed of having a better life
    C．were poor but somewhat happy
    D．lived a different life from their forefathers
    小题2:Why did the villagers agree to sell frogs?
    A．The frogs were easy money.
    B．They needed money to buy medicine.
    C．They wanted to please the visitors.
    D．The frogs made too much noise.
    小题3: What might be the cause of the children’s sickness?
    A．The crops didn’t do well.B．There were too many insects.
    C．The visitors brought in diseases.D．The pesticides were overused.
    小题4:What is meaning of the last sentence of the article?
    A．Happiness comes from peaceful life in the country.
    B．Money is important.
    C．The harmony between man and nature is important.
    D．Good old days will never be forgotten.

    It's very early in the morning and I'm sitting outside. It's also very cold and dark. With me is Jim Nightingale, and he is the reason I'm up so early. He passes me a hot cup of coffee. "Not long to wait now," he says. I hope he's right.
    After a few minutes there is a very weak light in the east, and then I hear a bird singing. It sings very loud and very clear. "That's the robin(知更鸟)," says Jim. A few more birds start singing with the robin and Jim knows the names of them too. Half an hour later, there are more and more birds singing, and it's very loud! Suddenly, all around us the air is full of the sound of birdsong. This is the dawn chorus(晨鸣), and it's beautiful.
    "Wow, this is amazing!" I tell Jim, who is smiling. "Is there a dawn chorus every morning?"
    "Birds can sing any time of the year but the best time is the end of winter and during the spring. This is when the birds sing most."
    "Really? So, why do they sing?" I ask.
    "Well, there are two reasons," explains Jim. "Most of the songbirds who sing are males. They want to find a female(雌性)so they sing to show how strong they are. The females listen and choose the best singer! The birds also sing to tell other males to go away. They need their own area; they don't like sharing with another male."
    I listen to the birds; the songs seem too much to me. "Do the birds sing a special song in the morning?"
    "That's a good question," replied Jim. "The successful birds have many kinds of calls and songs. Sometimes they copy the songs of other birds. This makes it sound like there are many birds in that place already and other males stay away. Also the female likes songs with different notes. Some birds, for example the European wren, have songs that contain over 700 different notes per minute!"
    So, how does Jim know so much about birds? Well, he works as a volunteer for the Royal Society for the Protection of Birds. He is trying to help the birds live in the modern world. "More and more of the birds' habitat disappears every year. The sparrow, for example, was a very common bird in the UK, now it's in danger."
    By now the sun is up and the birds are quiet. It's light so they can start looking for food, they need a big breakfast after all that singing.
    小题1:Why does the writer get up early in the morning?
    A．To visit her friend.B．To drink hot coffee.
    C．To see different birds.D．To hear birds sing.
    小题2:A bird sings early in the morning mainly_______.
    A．to call a female's attentionB．to fight with other males
    C．to find a place to live inD．to start looking for food
    小题3: According to the text, which of the following statements is true?
    A．At first the writer is happy to be up so early in the morning.
    B．Male birds have their own ways of fooling other birds.
    C．It's easier for the birds to find food early in the morning.
    D．Jim has a job with the Royal Society for the Proteciton of Birds.
    小题4:The text is mainly about_______.
    A．the robin's songsB．the birds' habitat
    C．why birds singD．how to protect birds

    Good health is very important. Everyone should do all he can to stay healthy. Being in good health means having both body and mind in good order, free from illness and pain.
    Good food, plenty of water, cleanness and plenty of rest all help in keeping our machines running as they should. Food does many things for our bodies. It gives what we need for keeping good health. It gives us energy for work and play. No food gives everything we need. We should eat foods of different kinds. Having enough to eat is not the same as having the right food.
    The water we drink helps wash away wastes formed inside our bodies. It also puts back the water we lose when we perspire(流汗). Our bodies are actually more than half water. We must drink enough to replace what we lose.
    We feel better and look better when we are clean. A bath every one or two days is a good rule for most of us. Brushing our teeth is important part of keeping clean.
    Sleep is the best kind of rest. Growing children need more sleep than grown-ups. Children's bodies not only have to be repaired; they also have to grow, No one's body can grow bigger properly while he is working and playing and wearing it out (疲劳).
    It has been useful to work for good health. Millions of years ago, people live only 20 years. Now people can live about 70 years. It has gone up 20 years just since the beginning of the present century.
    小题1:You should have foods of different kinds because _________.
    A．some foods are not good
    B．no food can give everything you need
    C．different foods taste different
    D．different people like different foods

When a restaurant plays classical music, people spend more money on food and drinks. When the restaurant plays modern music, people spend less money. Without music, people spend less.
