【推荐1】Chemicals are part of our daily life. All living and nonliving matter is made up of chemicals and virtually every man - made product includes the use of chemicals. Many chemicals can, when properly used, significantly contribute to the improvement of our quality of life, health and well-being. But other chemicals are highly hazardous and can negatively affect our health and environment when improperly managed.
Chemical safety is becoming an increasingly important topic around the world. I covers the handling and use of chemicals in a way that is safe for humans and the environment. It includes risk assessment and education in best and safe practices. It brings attention to potential danger and discusses safety in industrial, teaching and academic settings.
Chemical safety has many scientific and technical components. Among these are toxicology(毒物学)，ecotoxicology and the process of chemical risk assessment which requires a detailed knowledge of exposure and of biological effects.
The International Programme on Chemical Safety(IPCS) works to set up the scientific basis for the sound management of chemicals, and to strengthen national abilities for chemical safety.
Chemical Safety is achieved by undertaking all activities related to chemicals. It covers all chemicals, and the full range of exposure situations from the natural presence of chemicals in the environment to their extraction (提炼), industrial production, transport, use and handling.
The Chemical Safety programme helps to address proper use, handling, and storage of these materials. These activities are extremely vital to a safe working environment.
The production and use of chemicals continue to grow worldwide, particularly in developing countries. This is likely to result in greater negative effects on health if sound chemicals management is not ensured. Multisectoral(多部门的) action is urgently needed to protect human health from the harmful effects of improperly managed chemicals.

【推荐3】Although his 1-year-old smart-phone still works perfectly, Li Jijia already feels the need to replace it.
“There are many better ones available now. It's time to upgrade(更新）my phone.”
Li’s impatience is shared by many. Shortly after the season when new products are released（发布，发售）, many consumers feel the urge to upgrade their electronic equipment, even though the ones they have still work just fine.
As consumers’ minds are occupied by Apple’s newly released products and debate whether the Google tablet is better than the new Amazon Kindle, it might be time to take a step back and ask: “Do we really need the latest upgrades?”
According to Donald Norman, an American author, “planned obsolescence (淘汰）” is the trick behind the upgrading culture of today’s consumer electronics industry.
Electronics producers strategically release new upgrades periodically, both for hardware and software, so that customers on every level feel the need to buy the newest version.
“This is an old-time trick---they’re not inventing anything new,” Norman said. “This is a wasteful system through which companies--many of them producing personal electronics-- release poor-quality products simply because they know that, in six months or a year, they’ll put out a new one.”
But the new psychology of consumers is part of this system, as Norman admitted, “We now want something new, something pretty, the next shiny thing.” In its most recent year, Apple's profit margin(利润) was more than 21 percent. At Hewlett-Packard, the world’s biggest PC maker, it was only 7 percent.
Apple’s annual upgrades of its products create sales of millions of units as owners of one year’s MacBook or iPhone line up to buy the newest version, even when the changes are slight.
As to Li Jijia, the need for upgrading his smart-phone comes mainly from friends and classmates. When they are switching to the latest equipment, he worries about feeling left out.
“Some games require better hardware to run,” said Li. “If you don't join in, you lose part of the connection to your friends.”

【推荐1】Diseases spread in many ways. An infected person can cough or sneeze on someone nearby, or they can spread germs through a handshake. But sometimes we pick up germs indirectly. A sick person might leave behind bacteria or viruses when they touch a door handle, for example. But what if those surfaces could clean themselves?
Two teenagers from Hong Kong asked themselves the same question. Now they’ve developed a door handle that can kill germs on contact. The idea is simple. Every time the door is opened, the movement creates power that starts a germ-killing reaction on the handle. In lab tests, their system killed about 99.8 percent of the germs that they spread onto lab dishes covered with their material.
Research by others has shown that door handles in public areas are often home to lots of bacteria and viruses, notes 17-year-old Sum Ming (Simon) Wong. He and schoolmate Kin Pong (Michael) Li, 18, wanted to design a covering for door handles that would kill germs. After doing some research, they learned that a mineral called titanium dioxide (二氧化钛) is known to kill bacteria. It’s already used in many products, from paints to desserts. To make their covering, the teenagers made the mineral into a very fine powder.
Titanium dioxide kills bacteria best when lit by ultraviolet (紫外线的) light, says Simon. UV light is found in sunlight. But UV light does not naturally shine on indoor handles or any used at night, so the teenagers light their door handle from within. To make sure the light reaches the coated surface, the teenagers made their door handle out of clear glass. Each end fits into a bracket (托架). Inside one of the brackets is a strong light-emitting diode (LED). From it comes UV light. And here’s the interesting and praisable part: The power that makes the UV light shine comes from opening and closing the door. The power from the door is then carried by wire to the LED inside the door handle.
The door handle system, Michael and Simon say, might cost no more than about $13 (about 81 yuan) to build.

【推荐2】The idea that you can use humour, laughter, and play to make you healthier probably seems too simple to be true. However, it is really true and simple. The sense of humour, laughter and play plays an important part in keeping you healthy.
Treat the blues with a sense of humour, which is closely tied to laughter. Laughter is infectious. Have you ever heard a big laugh of a young child and been able to keep yourself from smiling? When laughter is shared between people, it makes them closer to each other and increases their happiness. Smiling is the beginning of laughter and a smile is also just as infectious as laughter is. You can experience something by smiling at everyone around you,and you will feel happier just by sharing a smile,even with a stranger.
Play is an important part of making sure that we stay healthy. We are often encouraged to make sure our children play,and are told of the benefits of being out playing. However, what we often forget is that it is just as important for old people to make play be part of their life as it’s for children. Physical play is important for the old and it certainly helps prevent illness. While the studies are still in the early stages, the studies that have been done have shown that physical play certainly plays a part in preventing cognitive (认知的) falling.
Anyway, adding humour, laughter, and play to our life will influence us mentally, physically and socially and bring us many advantages. So we should make full use of humour, laughter and play to make our life more active, more interesting and happier.

Sticking to a sleep routine
Reducing tech use before sleep
When we look at phone or tablet screens, the light from then activates our brains encourages brain activities and keeps us alert. This of course is the last thing that you need when you are going to sleep.
Even natural light will wake the brain up and this is also why you should do all that you can to ensure maximum levels of darkness in your bedroom. Even if you are able to fall asleep with the light on, your brain won’t allow you to fall into a deep sleep because the light which it recognizes will keep it alert.
Watching your diet
