Scientists in Britain and the United States have made a new kind of enzyme(酵素) that eats plastics(塑 料). With its help, plastics can be turned into smaller parts and go away quickly. Scientists believe that, in the future, it could solve the problem of plastic pollution.
The enzyme is able to break down PET, a form of plastic. PET was first made in the 1940s and is now widely used to make plastic bottles. It can remain in the environment for many years and pollute large areas of land and water. So it has always been a headache to deal with the waste from PET and other plastics.
The researchers made the discovery(发 现) while examining the structure of a natural enzyme in Japan. They found that the natural enzyme was helping to break down PET plastics. So, they decided to make small changes to the enzyme by adding some amino acids(氨 基 酸). It made the natural enzyme’s plastic-eating abilities work faster and better.
John McGeehan, one of the lead researchers, said, “We’ve made an improved enzyme. It’s better than the naturl one. And we are trying to make more improvements to it.” He went on, “The enzyme is not harmful to humans or animals,and it is friendly to the environment. So we are considering putting it into wider use.”
The team is now trying to make the enzyme break down PET in large quantities(大量的).
B．Advantages of Gardening D．Relationships with Neighbors
C．Healthy Eating Habits
“We’ll see that the plastic pollution may be stopped with this technology. However,there is still a long way to go,”John McGeehan added.

A cup of coffee is a good way for many people to start their day. It can also pass on kindness. Manyang Kher used to be a Sudanese child refugee(难民). When he was three years old, his village was burnt in the war. He was separated from his parents and never saw them again. He became one of the 20,000 young Sudanese who had to leave their home for Ethiopia’s Gambella area. He lived there as a refugee for 13 years.
When he was 16, Kher went to the United States. While he was in college, he started a program to help the refugees. Now, he owns a coffee company(公 司) called 734, which is a part of his program.The company has helped more than 200, 000 refugees living in the Gambella area till now. Kher said, “I know the difficulties and pains they face every day. You see kids die from hunger. You see kids dying of illnesses. You see kids running away from the refugee camp to find a place to be home, but die on the way.”
Eighty percent of the money made by the coffee company is used to send more of the children to school. And, as Kher explains, the money helps refugees to belp themselves. For example,a cup of 734 coffee can also buy one fishing net(网)for a refugee. They can fish for themselves.
Kher sells the coffee online and to coffee stores. Megan Murphy owns a coffee store in Washington, D.C. She serves 734 coffee in her store and people love it. The coffee tastes delicious, so it’
s a win-win on both sides.

A group of students from the US have been in China for a week. Here is part of their chat history (聊天记录) on WeChat. 20:45
Hi, everybody! Anything to share today?
20:49
Yes. I went to a restaurant to have dinner with some friends this evening.
When we finished the meal, the waiter brought us the bill. It was 270 yuan. We gave him 300 yuan and left 30 as a tip(小费) for his service(职务). To our surprise, he returned us the change!
Really? How kind he is!
20:53
@Sunny It’s different form that of the US. I worked in a restaurant in my free time.
I accepted tips. Well, something interesting happened to me this morning… 20:55
I couldn’t find the bus stop. I came up to a man who was walking near me and
showed him the bus number. He nodded and asked me to follow. We walked for about 10 minutes and finally got to the bus stop. I wanted to give him a hug (拥抱) to show thanks, but he just said goodbye and walked away. I couldn’t believe that he had taken so much trouble for a stranger(陌生人)!
It seems that Chinese people don’t usually hug.
I guess so. It’s really unforgettable!

And helpful. Well will enjoy the rest of our trip for sure. 66． How much was Sunny’s bill?
