Have you ever stayed in a hotel? Most Chinese hotels often provide guests with things like disposable(一次性) toothbrushes, toothpaste, shampoo and slippers. Many guests like the idea because they don't have to bring their own. But, if you travel to Beijing, remember to bring your own things. Starting from June, some hotels in Beijing will no longer provide guests with these disposable things. They want to ask people to use less disposable things.

    Many disposable things are made of plastic. People throw them away after only using them once. It is a waste of natural resources(资源) and is very bad for the environment. Do you know, one Chinese makes as much as 400kg of waste a year! Most of that waste comes from disposable things. In Beijing, people throw away about 19, 000 tons of plastic bags and 1, 320 tons of plastic lunch bowls every year! Plastic can take between 100 and 400 years to break down. So the less plastic we throw out, the better. So, wherever you travel, bring your own things and use them again and again.

    Back at home and at school, you can also do something, you can also do something to make our world a better place. Try to do these things in your daily life: Use cloth shopping bags, not plastic ones. After using a plastic bag, wash it out and let it dry. Then you can use it over and over again. Do not use paper cups. At your school canteen(食堂), use your own bowl and chopsticks instead of disposable ones.

    To protect our environment and our home, it is very necessary and important for us to save natural resources(资源).

What are fossils?

    Fossils are the remains of plants or animals. For such remains to be considered fossils, scientists have decided they have to be over 10,000 years old. The word fossil comes from the Latin word “fossilis”, which means, “dig up”.  Fossils can be divided into “body fossils” and “trace(痕迹) fossils”. Body fossils are the remains of a plant or animal's body. Trace fossils are the remains of the activity of an animal, such as footprints, egg shells, and nests.

How are fossils formed?

    Some animals were quickly covered after their death by sediment(沉淀物) like earth, mud or sand. Over time, the parts of the animals that didn't rot (usually the harder parts like bones and teeth) were covered in the newly formed sediment. Then, a lot of chemical changes happened to the animals bodies. Water with minerals(矿物质) went into the bone and took the place of the chemicals in the bone with rock-like minerals. In the end we get a heavy, rock-like copy of the original object - a fossil. There weren't any changes in size and shape when an object changed into a fossil, but the fossil of a bone doesn't have any bone in it! It is chemically more like a rock! According to scientists, fossils have been found on every continent(大陆) on Earth.

Ten years ago, I took up studying luck. I wanted to know why some people are always in the right place at the right time, while others always experience ill luck. Many people volunteered for my research. Over the years I interviewed them, watched their lives and had them take part in my experiments(实验).

I carried out a simple experiment to discover why there were differences in their ability to find lucky chances. I gave both lucky and unlucky people a newspaper and asked them to look through it and tell me how many photographs were inside. I had secretly placed a large message halfway through the newspaper saying, "Tell the researcher you have seen this and win $50." This message took up half of the page and was more than two inches(英尺) high. It was looking at everyone straight in the face, but unlucky people tended to(倾向于) miss it and lucky people tended to notice it.

Unlucky people are just more nervous than lucky people. They are busy looking only for what they need and this stops them from noticing the unexpected. As a result, they miss out on chances. Lucky people tend to be more relaxed and open. They can see everything that is in front of them, rather than just what they are looking for.

My research shows that lucky people live by several principles(原则). Here are some of these principles:

* Listen to your gut instincts(直觉) — they are often right.

* Be open to new experiences and break your normal thought patterns.

* Spend a few moments each day remembering things that went well.

* See yourself being lucky before an important meeting or phone call.

Should children do housework? Different people have different ideas. Some parents will say that their children are too busy for housework. Other parents will ask their children to do housework，but the housework doesn't get done. That's a problem. 

Doing housework is good for children. Doing housework helps them develop an awareness of the needs of others. One small study，done over a period of 25 years，found that young adults will succeed in their mid﹣20s depend on whether they took part in housework tasks at the age of 3 or 4. Those who early shouldered responsibilities developed a sense of responsibility in other areas of their lives. 

But few kids are doing much around the house at all. In a survey of 1，000 American parents，75 percent said they believed doing housework made kids" more responsible". Yet only 36 percent of those said they required their children to do housework. 

Sports and homework are not the housework﹣free reasons. The goal，after all，is to raise a kind of adults who can balance a caring role in their families and communities. Housework teaches that balance. 

What should you do when getting children to do housework? Never accept their excuses. Don't worry if you must repeat yourself again and again. If you're spending more time getting the child to do housework than it would take to do it yourself，then you're doing it right. Can a payment help?I don't think so. If you're trying to teach kids to shoulder the responsibility of a home，paying them for housework is not the right choice.
