Recycling is a way to take trash and turn it into new products. There are a number of different recycling processes that allow materials to be used more than once.

All kinds of materials can be recycled. Some of the most common processes in use today involve(牵涉) recycling plastic, glass, metals , paper, electronics and so on. Items made of these materials include soda cans, plastic boxes, newspapers, old computers, and cardboard boxes.

There are many steps in recycling. It isn’t actually a simple process and is different for each type of material. For example, paper starts its recycling process by being mixed with water and other chemicals to break it down. This process finally turns the paper into a pulp(纸浆). Then remove the plastics and other useless materials from the pulp. After that, it gets cleaned. Now the pulp is ready to be made into new paper.

However, computers and batteries(电池) are usually recycled in order to remove harmful chemicals as well as to find again some valuable materials such as gold.

In general, we should follow different steps in the recycling process. These steps are:

•Collecting recyclable materials, like cans and plastic bottles.

•Processing(加工) the old materials and making new items.

•Buying items made from recycled materials.

The 2015 Nobel Prizes have been announced. Sweden's Nobel Prize committee said the Nobel Prize for medicine will go to scientists from Ireland, Japan and China. William Campbell from Ireland and Satoshi Omura from Japan share the prize for their discovery of the drug avcrmectin(除虫菌素).The prize for medicine is also going to Tu Youyou. She discovered artemisinin(青蒿素). Artemisinin is a drug that has greatly lowered the number of people who die from malaria(疟疾). The committee said her greatest achievement is that discovery of artemisinin has given the world new ways to fight against two serious diseases. That's why Ms. Tu got the prize. It is said those diseases influence millions of people every year.

Ms. Tu is the chief professor at the China Academy of Traditional Medicine. She is also the first Chinese citizen to be awarded the Nobel Prize in medicine. It took her great and painful effort to make the great discovery. She always tested the medicine by herself and her liver(肝) got badly hurt. From 1972 to 2012, Ms. Tu went through about 40 failures before she succeeded. But she never gave up and always fought on.

A member of the Nobel committee said that the award for Tu Youyou is the result of a great change in the way that Chinese do scientific research. He says China has spent a lot of money on this kind of research. This member also said that the work of the three scientists could help end the health risk of diseases affecting 3.4 billion people.

1.Is Ms. Tu the first Chinese citizen to win the Nobel prize for medicine?

2.How long did it take her to make the discovery?

3.What is her greatest achievement?
