Dear Jim,
How is everything going? Known that you are curious about Peking Opera, I'm more than glad to introduce it to you.
Dating back to late 18th century, Peking Opera becomes fully developed and recognized during the Qing Dynasty. As a combination of music, vocal performance or dance, Peking Opera can offer audience with a feast for the eyes and ears. Performer wear colorful costumes and make-ups, that are in line with the personalities of the roles that they play.
I high recommend you visit the Mei Lanfang Theater to see a Peking Opera show. Hopefully, my introduction has helped you well understand Peking Opera than before. If you have any question, don't hesitate to ask myself.
阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。
Most of us have recently experienced quarantine (隔离) to minimize the risk of meeting somebody who may be carrying the virus. It is certain 1. being under quarantine is no fun. However, with our access to food, 2. (deliver) services and the entertainment 3. (offer) by the internet, we're actually very lucky. Let's take a quick look at the history of quarantines.
The idea of quarantining sick people dates 4. ancient times. Yet the word "quarantine" first came into use in the 14th century Europe during the Black Death. People were dropping like flies from the mysterious disease, and as the death toll climbed into the millions—eventually killing 5. (approximate) half of the European population, cities began to take 6. (measure) to protect their citizens. The port city of Venice, Italy, was an important trading center with ships 7. (come) from all corners of the Earth every day. If a ship 8. (suspect) to be harboring the plague (瘟疫)，it was sent to 9. offshore quarantine and ordered to wait there for 40 days when those abroad either recovered, or 10. (likely), died. The waiting period gave rise to the term quarantinario, from the Italian word for 40.
I was once the guide on a wildlife-photography trip to the North Pole, where wildlife is _____ . After two days of travel, we reached a fjord (峡湾)and ___ several seals resting on the ice. I wished to get a picture of a seal as it came up for breath at a hole. Therefore, I __ my camera and a motion sensor near the edge of a hole.
At two in the morning, a colleague __ us. He had noticed a polar bear approaching in the distance. We ran to the __ of the boat to see what would happen. At first the bear walked toward the boat. Then it turned and __ directly for my camera. The motion sensor __ to its movement, starting the camera to take pictures. The bear ____ the camera, gently sniffing it.
__ the bear knocked the camera into the hole! My camera and all those __ pictures is appeared beneath the ____.
____, a year later, I joined a similar trip to the same spot. I obtained __ to bring a remotely operated vehicle (ROV) and a colleague to __ it. We would try to __ the camera.
When we arrived back and set out our search, we __ technical difficulties almost immediately and had to pull the ROV out of water twice. However, on the third try, the ROV caught hold of the camera. As we eventually got the camera up, we __ loudly. I managed to take the memory card out and later __ all 149 photos.
Regaining that camera is the most satisfying __ of my career. I have never experienced such a __ of excitement when we pulled that camera out of the water.

While marathon study sessions may be unavoidable sometimes, do your best to manage your time effectively.
Reduce your workload by studying more efficiently. Before you start studying, always read your task sheet to make sure you’re focusing on the right topics. 1. This saves you time looking it up. Finally, pick out the most important information, so you can study it first.
2. Make sure you have everything you need, so you won't need to get up every few minutes to get something. Neatly place your textbooks, pens, notebook and other study materials in your study space. This way you can easily get what you need without taking an unplanned break. Plan out your study sessions in advance. Think about the time you'll need for each task, add 10% extra time for insurance, and then schedule blocks for your tasks. 3. Remember to include short breaks every hour or so.
Break up difficult tasks into smaller steps. Tasks such as “Study for History Final” or “Write Term Paper” can seem unapproachable. Instead of getting confused and upset, divide big tasks into small ones If you’re studying for a final of a course, start by looking over past tests and quizzes. 4.Smaller study tasks may also include creating outlines that summarize textbook chapters.
Do your best to space out your study sessions instead of cramming （突击）.Whenever possible, give yourself time to study a little bit at a time. It’s better to study for 3 separate 3-hour sessions instead of 1 marathon 9-hour session. 5.
A.Choose a quiet spot for studying.
B.Prepare your area before you start studying.
C.Schedule your toughest and most important tasks first.
D.Study difficult subjects first to get them out of the way.
E.Then divide the course into its units, and study one unit at a time.
F.Additionally, ask your instructor to explain any topic that confuses you.
G.Multiple shorter sessions will help you remember more information in the long run.
Around 45% of plastic waste is recycled annually in the UK and is on the increase. However, one of the problems with present plastic recycling methods is that you end up with a lower-quality plastic with worse properties （特性）than the original. This means that plastic drink bottles cannot simply be recycled into new drink bottles continuously, but instead are used for other lower-grade products like park benches.
Now, British scientists have developed a new method of chemical recycling. They use lower temperatures and more environmentally-friendly starting chemicals than previous methods to turn plastics back into their constituent chemical molecules （分子）.In this way, they can be used to make new plastics of the same quality as the original.
"Most plastic is now recycled using mechanical methods, where they are transformed into liquids before being made into something new," said a professor named Matthew Jones. "The problem is, melting plastic changes its properties and reduces the quality. Out method of chemical recycling overcomes this problem. Then plastics can be used all over again without losing any properties?"
The researchers are recycling some kinds of plastics, including plant-based PLA, a plastic used for food packaging and PET, which is used for drink bottles. So far, the technology has only been demonstrated on a small range. However, scientists are now working to produce larger quantities of starting chemicals.
"There is no single solution to the problem of plastic waste — the approach has to be a combination of reducing, reusing and recycling. Our method of chemical recycling could allow carbon to be recycled endlessly rather than digging more up from the ground in the form of fossil fuels, or letting it into the atmosphere as a greenhouse gas," said Dr. Paul McKeown from the University of Bath.
1.What is the problem with the present plastic recycling?
A.The quality of recycled plastics declines.
B.Plastic drink bottles cannot be recycled.
C.The amount of plastic waste is increasing.
D.Recycled lower-grade products sell badly.
2.How do scientists recycle plastic waste with the new method?
A.By transforming it into fuels.
B.By heating it into liquid state.
C.By keeping its original properties.
D.By changing its molecule structure.
3.What can we learn from what Dr. Paul McKeown said?
A.Fossil fuels are endless resources.
B.The plastic waste problem has no solution.
C.Recycled carbon leads to greenhouse gases.
D.The chemical recycling is environment-friendly.
4.In which part of the website can we find the text?
A.Business. B.Tech & Science.
C.Lifestyle. D.Arts & Culture
