【题目】 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 natural 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
). “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.
【1】Which is not true about the advantage of enzyme?
A.It’s able to make plastics become smaller parts.
B.It can solve the problem of the plastic pollution right now.
C.It’s used to make the plastics disappear in a rapid way.
【2】The underlined phrase “break down” in the passage probably means “________” in Chinese.
A.实验B.生产C.分解
【3】Which isn't the change they made to the natural enzyme?
A.Some amino acids were put in it.
B.The speed of plastic-eating has been improved.
C.The quality of plastic -eating remained the same.
【4】Which of the following is TRUE according to the passage?
A.The scientists are still trying to improve the enzyme.
B.The enzyme will pollute large areas of land and water.
C.The natural enzyme woks better than the improved one.
【5】We can’t infer from the study that________.
A.The team is able to increase the speed of the plastic -eating abilities
B.Efforts are made to increase the number of PET that the enzyme breaks down
C.Few efforts are required to the improvement of this new enzyme

【题目】 Everybody knows how important it is for students to get a good night's sleep every night. You aren't able to do your best and keep up with all of your responsibilities unless you sleep well. I'm sure you already know that you should go to bed at a reasonable hour. Most experts agree that the ideal number of hours is eight, and his has been accepted as common sense for as long as I can remember. However, I was young once and I know that most of you get much less sleep than that—and in some cases it will be affecting your schoolwork.
I read an interesting article in a teachers' magazine recently. they did a study of 848 students in Wales. Worryingly, the results showed that teenagers are facing a new problem. They may go to bed get up at suitable times but a growing number are waking up in the middle of the night, not to use bathroom or have a snack but because of a new phenomenon: FOMO-fear of missing out!
According to the article, schoolchildren are suffering because of a growing trend（趋势）to wake up during the night to check social media. Afraid of missing a comment or opportunity to take part in a chat teenagers are waking at all times of the night, going online and getting involved. All this happens when they should be sound asleep.
Experts are worried about this growing trend and the report gives some worrying results that I'd like to share with you: 23% of 12 to 15-year-olds wake up nearly every night to use social media. Another 15% wake up at night once a week for the same reason. One in three students are often tired and unable to behave energetically in the daytime. Students who use social media during the night are more likely to suffer from depression and anxiety.
So, I'd like to ask you to be responsible when it comes to social media. Be brave! Switch off your devices at night. The world won't end and your social media will be waiting to greet you in the morning! I give you my word that you won't have missed anything important.
