1 . You may see some unusual fruit and vegetables when you visit a large supermarket, such as square watermelons, blue potatoes and purple cauliflower (菜花). So, why are they so unusual?
Some plants are unusual because they are grown in special ways. For example, square watermelons grow inside square glass cases. The square watermelon result is a specially shaped melon that is easy to cut and store in the fridge. People also grow heart-shaped tomatoes in the similar way. You can do this as well with your own backyard watermelons and tomatoes!
Some plants are designed when they are seeds (种子). Hybrids (杂交) are new plants created by scientists. They are a combination (结合) of different “parent” plants that form a whole new kind of plant. For example, a fruit called the pluot is a cross between a plum and an apricot. It looks like a plum, but it is sweeter than most plums. Crossbreeding (杂交繁育) is when two plants of the same kind are combined to create a better plant. A farmer might crossbreed a small, sweet tomato and a large but tasteless tomato in order to create a large, sweet tomato. It will provide delicious slices that fit better on sandwiches. Farmers must choose the plants with qualities that people want and then grow more of these plants.
The next time you go to the supermarket and see a square watermelon or pluot, remember how much work went into producing it.

2 . Nowadays, there are more and more TV talent shows. They are very popular all over China. These talent shows give everyone a chance to show off their talents. For some lucky people, these shows may make them famous, and can even make them rich. However, there are also many bad sides. First, some young people just imitate(模仿)the people they love. They may forget about their own style. Second, young people spend too much time on such TV shows. They always dream of being a star, so they spend less time on their studies.
I think TV talent shows are social activities. Young people can join in these activities to get social experience. But they should know that the chance of being famous is very small for most people and they should know that their schoolwork is much more important. In a word, you can do what you like, but you should know what is important and what is not.

Levi Strauss was born in Germany in the mid 1800’s and immigrated(移居) to the United States as a young man. He lived in New York City and learned the dry-goods business for several years. In 1853 he took his knowledge and his dreams to San Francisco (California, USA). His dream to succeed came true over the next 20 years as he became a very successful businessman.
Many of Levi Strauss’ customers were cowboys and miners. They needed clothing that was strong and lasting. Strauss found a special cloth from France that was comfortable and lasted a long time. It was called “serge and mines” which was later shortened to the word “denim(粗棉布)”.
Another man named Jacob Davis bought large amounts of the denim cloth from Levi Strauss. He was a tailor who made pants for hard-working men. One of his customers was continually tearing the pockets off his pants. So Jacob Davis decided to put rivets(铆钉)on certain parts of the pants to make them stronger. The customer loved the new pants so much that he told all his friends, and soon Jacob Davis was busy making lots of pants with rivets.
Jacob Davis soon realized that using rivets was a great business idea, and he didn’t want anybody to steal that idea. He decided that he would need to get a patent. But being a poor tailor, he didn’t have money to pay for the patent. After thinking it over, he went to the businessman Levi Strauss and told him his idea. He said, “If you agree to pay for the patent, we will share the profits from the riveted pants.” Levi Strauss did agree, and the new riveted pant business was called Levi Strauss and Company. Today Levi’s jeans are more popular than ever, and Levi’s name continues to live in.
