Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.

Although there are many different types of food, some animals spend their lives eating only one type. The giant panda（大熊猫）eats only one particular type of bamboo（竹子）. Other animals eat only one type of food even when given the choice. A kind of white butterfly（蝴蝶）will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet（多样化饮食）. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.

Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

Many college students have after-school jobs. Students both go to school and have a job at the same time. Every student has his or her own reason for having an after-school job. The most common reason is to help pay for college. In the US, going to a college or university may be very expensive. Not only must students pay for classes, they must also pay for a place to live, food, and other expenses. Buying books for classes can also be very expensive. Students spend as much as five hundred US dollars on books. Many parents do not have enough money to pay all of these expenses, so the students must get an after-school job to help pay for his or her education.?

Other students have after-school jobs not to pay for college, but to make and save a little money. Even after all of the school fees are paid, students often have many other expenses.

Because of this, many students try to find jobs so that they can have fun as well as study.?

Some students get after-school jobs simply to gain more experience. If a student has never worked before, he or she can have the opportunity to have his or her first job.

If a student is interested in working in a library after he or she graduates from college, the student can often find a job at the college library. There are many job opportunities for students who are interested in gaining experience in the area his or her choice.?

Though some people feel that after-school jobs take away from a student's time to do his or her homework, working is a great learning experience that happens outside of the ?classroom, and can provide many new opportunities for the students.

A well-dressed man came into a famous jeweler shop. He explained that he wished to buy a pearl (珍珠) for his wife's birthday and that the price didn't matter since business had been very good for him that year. After examining a number of beautiful and valuable pearls, he chose a nice black one that cost $ 5,000. He paid for the pearl, shook hands with the jeweler and left.

    A few days later the man returned and said his wife had liked the pearl so much that she wanted another one just like it. It had to be exactly the same size and quality(质地) as she wanted a pair of earrings (耳环) made. "Can you give me any advice on how to get such a pearl?" said the man. The jeweler replied,   "I would say it's nearly impossible to find an exact one like that pearl.”

"I inherited(继承) it from my mother, and my mother inherited from hers. But now I really need the money. "

    The jeweler was quick to pay her before she changed her mind. Then he called the rich man’s hotel to tell him the good news. The rich man, however, was nowhere to be found.
