Ring, ring, ring, the alarm bell sounds. It’s school time again! After a long holiday, are you ready for the new term? You may feel excited to see your classmates, or a little nervous about the coming schoolwork. Heading back to school is a time of transition(过渡). How can we fit in the new term? Here are some ways to make the transition from holiday to school a little easier.
It’s very normal to feel nervous on the first day of school. Getting back to the school routines(常规) and fitting in new school work take some time after a long break. So how can we deal with(处理) our worries? Just think about your first day in the past years. Everything will go well once you get used to it. Just relax and wait.
People say “a good beginning is half done” A good plan is surely needed before the new term. Think about what you can do better this term than the last. Make a plan and try to go for it!
If you went to bed and got up late during the holiday, you will have to change your body clock back to normal. Go to bed earlier the week before classes start. This way, you won’t be tired after the first few days of school. Also, having some warm-ups is helpful. Doing exercise and practicing morning reading every day are some other good ideas to get ready for the new school-year schedule.
It makes you feel good if you are prepared and have all the things you need. Check all the homework you need to do a week earlier. And it’s better to pack your schoolbag the night before school starts.
What about wearing something you like? Maybe you got a new schoolbag during the holiday, or new sports shoes that can put a spring in your step. If you wear a school uniform, you can wear your favorite watch or a new hair band to show your personal style.

【推荐3】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). “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.

【推荐1】What are you holding in your hand while you are taking the examination?
Right. A pen.
Though it is small, the pen has changed the history, improved the trade of countries, recorded events, carried news, and done far more work for human beings than all other tools. Without it, progress (社会的进步) would have been almost impossible. The invention of the wheel, the introduction of the steam engine (蒸汽机), the use of electricity, all these have changed the lives of millions of people, but the pen has done more. It has taken away mountains, and it has prepared the way for all progress and development of society.
In the past the pen did all the work if you wanted to keep any writing for some time. The lawyers (律师) took up their pens and wrote the law of the country from the days when papyrus (纸莎草纸) was first used. The most famous letters in the world were written with a pen. It was with a pen that the greatest thinkers of all time wrote down their thoughts.
The pen is very utilitarian. We cannot sign a bill or write a letter or buy a house without our pen. An agreement is worthless till our name is written with a pen. The writers encourage the world with it. The students take their examinations with it as well.
Our coming into the world is recorded with a pen. Before we have been at school, our name is written on the name list with a pen. We cannot be married until we have signed. A pen records the important events in our life.
Let’s remember that we hold in our hand the most powerful instrument which man owns. The pen is a magic tool. Whenever you use it, enjoy it.

【推荐2】We all know plastic pollution has become a serious problem. One million plastic drinking bottles are thrown away every minute. What if we could use plastic waste to build roads? This is exactly what Toby Mc Cartney has done.
In 2019, McCartney’s UK-based company, MacRebur, built a plastic road in Elgin town, Scotland. The plastic waste was made into grains (颗粒) and then mixed with bitumen (沥青). The road looks just like any other road. But it has improved strength and is more stretchy (有弹性的) thanks to the plastic.
“Our technology can not only help solve the problem of plastic waste but also produce roads that deal better with changes in the weather,” McCartney said.
McCartney’s idea came from a trip to India. “I saw people in India would put plastic waste into potholes (路面的坑洼) and burn it. The plastic would melt down (融化) and fill the holes,” said McCartney.
“I knew that there must be some correspondences between plastic and bitumen, which both come from oil. That’s how I started to think about mixing them,” he said.
After lots of testing, McCartney found the perfect method. And now his company has built many plastic roads around the world. A one-kilometer stretch of road uses about 684,000 plastic bottles or 1.8 million plastic bags. The road itself can be recycled and the materials can be reused to build new roads.
“We’re just a small part of ending the plastic problems, but it’s nice to be part of it,” McCartney said. “I just don’t want my daughters to live in a world where there are more plastics in the ocean than fish.”

【推荐3】French doctors and American scientists have reported doing an operation(手术)in which the doctor was outside the operating room. This kind of operation is known as robotic operation. Doctor Marescaux did the operation in an office in New York City last month, while a sixty-eight-year-old woman patient was in a hospital in Strasbourg, France.
A doctor in Strasbourg got the patient ready. He placed medical tools and a small video camera in her stomach area. Doctor Marescaux in New York watched the patient on a video screen. Then he used the computer to send messages to the robot machine. The robot moved the tools that cut the woman's gallbladder(胆囊)away. The woman got well soon after the operation and left the hospital two days later.
Experts(专家)say such a robotic operation is based on high- speed telecommunications(远程通讯) between the doctor and the robot. Technology must be able to send a doctor's order to a robot to move the tools quickly.
Experts also say a successful robotic operation will improve an operation. For example, the robot can make much smaller movements(动作)than a person can. A robot machine can turn tools in ways that a doctor's hand cannot.
Doctors say such a robotic operation will make safer and better operations in the future. They say it will improve doctor training. It will also mean that doctors could do an operation on people in dangerous places far away. And it could mean that people could have operations done by top doctors without having to travel to the city where doctors work.
