   The population of the Earth is growing faster. It is important that we look after the Earth. We need it! The Earth gives us a lot of things. We also give the Earth a lot, but some of the things are not good.

   In nature, when something dies, other animals and plants get food from it. Every animal or plant gives food for other animals or plants. However, animals can't get food from many of the things that we "give"the Earth. Animals and plants can't eat metal, plastic and glass. These things will stay in the ground for many, many years.
   Some rubbish is very dangerous for plants and animals. In some places, many animals live together. One animal makes food for many more animals. If we put rubbish and chemicals in the water, the plankton(浮游生物) can die. If there isn't any plankton, many animals have nothing to eat.
   So what can we do? Don't leave any rubbish in the countryside! Don't make so much rubbish!

（1）、The Earth gives us ___________.

A、food B、rubbish C、chemicals D、pollution

You want to know about my staying in America, right? Well, to tell you the truth, it is really an eye-opening experience to study here.
In China, I had English classes five times a week since fifth grade. However, I didn't know how different textbook English could be from everyday English until I came to Hotchkiss School, Connecticut.
When I first studied English, I was told to say,” I am fine” when people say “How are you?” But in the US, I found that people say, “I am good” or “I'm tired”.
One day, someone greeted me with “What's up?” It made me confused . I thought for a moment and then smiled because I didn't know what to say.
Since then, I have discovered more and more differences between Chinese and US cultures.
To my surprise, US girls spend a lot of time in the burning sun to get a tan(晒黑). However, in China, girls try every possible way to get their skin paler, or “whiter”.
I was also surprised by how hardworking US students are. In China, schoolwork is almost everything, so we study hard and that's it. But here, a “good” student gets good grades, does a lot for the public and plays sports or music.
The kids here are so talented, I am starting to be sorry that I gave up playing the piano at an early age and that I have never thought about sports.

    What do you want to be when you grow up? A teacher? A doctor? How about an ice-cream taster?
    Yes, there really is a job where you can get paid to taste ice cream. Just ask John Harrison, an “Official Taste Tester” for the past 2l years. Harrison's job has been responsible for approving（批准）large numbers of the sweet ice cream – as well as for developing over 15 flavors（味道）.
    Some people think that it would be easy to do this job; after all, you just have to like ice cream, right? No – there's more to the job than that, says Harrison, who has a degree in chemistry. He points out that a dairy or food-science degree would be very useful to someone wanting a job in this “cool field”.
    In a typical morning on the job, Harrison tastes and grades 60 ice-cream samples. He lets the ice cream warm up to about 12^oF. Harrison explains, “You get more flavor from warmer ice cream, which is why some kids like to stir it, creating ice-cream soup.”
    While the ice cream warms up, Harrison looks over the samples and grades each one on its appearance. “Tasting begins with the eyes,” he explains. He checks to see if the ice cream is attractive and asks himself, “Does the product have the colour expected from that flavor?” Next it's time to taste!
    Continuing to think up new ideas, try out new flavors and test samples from so many kinds of ice cream each day keeps Harrison busy but happy – working at one cool job.

      Hip hop or rap (说唱） music as it is also called, started on the street and in the clubs of the New York City in the 1970s . But today many countries have their own kind of hip hop music . This kind of music comes from reggae, disco and funk music . Rapping means speaking to the rhythm of the music, and it is an important part of the music . People rap to express how they feel about their lives and problems .
Rapping in class.
       Would you like to rap in class? Well actually, hip pop music is played in more than 10,000 schools in the USA .Why ? There is a new school program called “ Flocabulary ”in which teachers use texts and hip hop CDs to help teach different school subjects . The words of the songs are just what students are studying . This makes learning easy and fun . Students and teachers are excited about the positive results it has had on exam marks . One teacher said, “ I've used hip hop songs in class, and I have never seen my students so crazy about history ! You can't imagine how well they imagine how well they remember what I teach ! We even try to write our own songs . ”
Whose idea was Flocabulary?
     Blake Harrison, a high school student, was the first person to come up with the idea of Flocabulary . The word “ Flocabulary ” comes from the word “ flow ” and “ vocabulary ” . “ Flow ” is a rap word for “ style ”,or the way a rapper says the words of a song . “ Vocabulary ” means the words you have to learn in a language . How did he get the idea ? Well, he realized he could remember the words of a hip hop song very easily . So,why not make lessons into songs ? Today together with Alex Rappaport, a song writer, Blake produces hip hop songs for maths, science and literature (文学）. They are now used in schools with great success .

      If you do not use your arms or your legs for some time, they will become weak, when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way.
     When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong.
      If a friend says that his arms and legs are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents may be blamed(责备), and few of us know that it is just his own fault. Have you ever found that some people can't read or write but usually they have better memories ? This is because they cannot read or write and they have to remember things, they cannot write them down in a small notebook. They have to remember days, names, songs and stories, so their memory is the whole time being exercised.
So if you want to have a good memory, learn from the people: practise remembering things in a way as other people do.
