Have you ever stayed in a hotel? Most Chinese hotels often provide guests with things like disposable (一次性的) 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 disposables. They want to ask people to use less disposable things.
Many disposable things are made of plastic(塑料). People throw them away after only using them once. It is a waste of natural resources and is very bad for the environment. Do you know, one Chinese person 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 school, 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.

Invention is a creative process. An open and curious mind enables one to see beyond what is known. Seeing a new possibility, a new connection or relationship can spark(引发) an invention. Inventive thinking frequently involves combining concepts or elements from different fields that would not normally be put together. Sometimes inventors skip over the boundaries between separate fields. Ways of thinking, materials, processes or tools from one field are used as no one else has imagined in a different field.
Play can lead to invention. Childhood curiosity like playing in a sand box, imagination can develop one’s play nature—an inner need according to Carl Jung. Inventors feel the need to play with things that interest them, and to explore, and this internal drive brings about interesting creations.
Inventing can also be an obsession(痴迷). Inventors often imagine a new idea, seeing it in their mind’s eye. New ideas can arise when the conscious mind turns away from the subject or problem; or when the focus is on something else; or even while relaxing or sleeping. An unusual idea may come all of a sudden! For example, after years of working to figure out the general theory of relativity, the solution came to Einstein suddenly in a dream “like a giant die making an unforgettable impress, a huge map of the universe summarized itself in one clear vision”.
Invention can also be accidental. Insight(洞察力) is also an important element of invention. It may begin with questions or doubt. It may begin by recognizing something unusual. It may be useful and it could open a new way for exploration. For example, the odd metallic color of plastic made by accidentally adding too much catalyst(催化剂) led scientists to explore its metal-like properties(性能). They then invented electrically conductive plastic and light emitting(散发) plastic—an invention that won the Nobel Prize in 2000 and has led to new kind of lighting, display screens, wallpaper and much more.
