Dr Chris Idzikowski, 3. (direct) of the Edinburgh Sleep Centre, said the idea could help people get off to sleep. He 4. (explain) that “There’s plenty of scientific evidence to show that sleep starts at the beginning of the night 5. body temperature starts to drop. The drop occurs partly because the blood vessels (血管) 6. the hands, face and feet open up and release heat.” “A warm bed –approximately 20 to 24 degrees Celsuis –is 7. good way to start this process while a cold bed isn’t. It helps people sleep well especially as it’s taking much 8. (long) for them to warm up when they come in from the snow.”

Are you looking for a new pastime that will create a balance between physical activity and relaxation? Then yoga may be the perfect choice for you. Yoga can be practiced by people of all ages and levels of fitness.1. It's a great way to strengthen your muscles and become more flexible.
In the 1930s, Indian Sri Tirumali and K. Pattabhi developed one of the most popular forms of yoga practised worldwide today. They worked together using an ancient Sansknt text called Yoga Korunta to create a set routine of yoga movements and breathing exercises. 2.
Ashtanga is different from other forms of yoga. It is a very powerful form of aerobic (有氧的)exercise which creates deep heat in the body. 3. In other forms of yoga, however, the routine can change each time and the stretching exercises aren't aerobic.
4.As well as making you stronger and more flexible, it can also help you to stay calm. By focusing on your breathing while doing physical exercise, you are able to get a balance between mind and body. In addition, yoga helps to make us healthier so we are less likely to get common illnesses like colds.
Furthermore, yoga encourages you to think about what you're doing. Often you will close your eyes while doing certain movements.5.After a few lessons you'll stop looking at what the others around you are doing. You will stop comparing yourself and start focusing on yourself.
A. It can also be done anywhere at any time.
B. The result of their co-operation was ashtanga yoga.
C. Whatever kind of yoga you choose, there are many long-term benefits.
D. This allows you to concentrate better and it makes you less competitive.
E. Every time someone practices ashtanga, he or she does exactly the same movements.
F. If you're interested in yoga, but can find a class near you, then it might be an excuse to travel.
G. Recently, it has become extremely common for beginners as well as advanced yoga students to go on yoga holidays.
Shark attacks not only disturb beach activities, but can affect associated tourist industries. Shark nets are a common solution to preventing shark attacks on beaches, but they cause dangers to sea ecosystems.
Seeking a cost-effective way to monitor beach safety over large areas, we have developed a system called Shark Spotter. It combines artificial intelligence (AI), computing power, and drone (无人机) technology to identify and warn lifesavers to sharks near swimmers. The project is a cooperation between the University of Technology Sydney and The Ripper Group, which is pioneering the use of drones—called “Westpac Little Ripper Lifesavers”—in the search and rescue movement in Australia.
SharkSpotter can detect sharks and other potential threats using real-time aerial imagery. The system analyses video from a camera attached to a drone to monitor beaches for sharks, send warnings, and conduct rescues. Developed with techniques known as “deep learning”, the Shark Spotter system receives imagery from the drone camera and attempts to identify all objects in the scene. Once certain objects are detected, they are put into one of 16 categories: shark, whale, dolphin, rays, different types of boats, surfers, and swimmers.
If a shark is detected, Shark Spotter provides both a visual sign on the computer screen and an audible warning to the operator. The operator confirms the warning and sends text messages from the Shark Spotter system to the Surf Life Savers for further action. In an emergency, the drone is equipped with a lifesaving flotation pod (漂浮仓) together with an electronic shark repellent (驱逐装置) that can be dropped into the water in cases where swimmers are in severe trouble, trapped in a rip, or if there are sharks close by.
In January 2018, the Westpac Little Ripper Lifesavers was used to rescue two young swimmers caught in a rip at Lennox Head, NSW. The drone flew down the beach some 800 meters from the lifeguard station, and a lifesaving flotation pod was dropped from the drone. The complete rescue operation took 70 seconds.
We believe Shark Spotter is a win-win for both marine life and beachgoers. This unique technology combines dynamic video image processing AI and advanced drone technology to creatively deal with the global challenge of ensuring safe beaches, protecting environments, and promoting tourism.

Most of us have looked up at the stars that fill the night sky and wondered whether we’re alone in the universe. Indeed, the question of whether there’ s life out there has been something humankind ’s been asking itself for countless years. But thanks to China’s Five-hundred-meter Aperture Spherical Telescope (FAST), the answer to this question may come a lot sooner than we expected.
The telescope has a huge round reflector, which measures 500 meters across and has a perimeter（周长）of 1.6 kilometers. Because of its great size, it would have been both difficult and inefficient to get FAST to move like a regular telescope. Instead, FAST’s designers came up with a great solution: its surface is made up of 4450 panels which can be individually adjusted. This clever design feature allows scientists to detect radio signals from any angle with a great degree of accuracy. “Panels can change their positions through connected wires and parallel （关联的） robots. We can control their position with an accuracy of 1 mm,” Zheng Yuanpeng, chief engineer of the telescope’s panel project, told Xinhua News Agency.
FAST’s engineers also had the task of finding a suitable location. As any interference would affect its ability to detect distant radio waves, it needed to be built in a remote area. Luckily, the perfect spot was found in the beautiful mountains of Guizhou Province. “There are three hills about 500 meters away from one another, creating a valley that is perfect to support the telescope," Sun Caihong, chief engineer of FAST’ s construction, told Xinhua.
And although it wasn’t yet fully operated, FAST had already made great discoveries by October 2017. Since 1967, only around 2000 pulsars （脉冲星） have been discovered, yet FAST had detected six more by October 2017. Once FAST is fully up and running, we may finally have the answer to one of the biggest questions in history.
1.What is the purpose of mentioning the question in Paragraph 1?
A.To introduce the new giant telescope.
B.To explain why there is life in universe.
C.To remind readers to think about the life in space.
D.To emphasize the question that should be answered.
2.What can we know from Paragraph 2?
A.The telescope is made up of many panels.
B.The area of FAST is about 800 square kilometers.
C.The engineer can handle FAST’s position accurately.
D.The individual panel helps scientists catch radio signals.
3.Why was FAST built in Guizhou?
A.Because Guizhou is a remote province.
B.Because Guizhou has an ideal valley.
C.Because Guizhou has beautiful mountains.
D.Because Guizhou has the ability to build it.
4.What does the last paragraph mainly talk about?
A.FAST’s timeline. B.FAST’s future.
C.FAST’s operation. D.FAST’s discoveries.
I was in the seventh grade, and we had moved to New Jersey in November. By then, everyone already had had their own friends, and no one wanted to talk to a new girl. To make things worse, they put me in “Section L”. I found out later that everyone called Section L “Loserville”. It was sort of an open secret that it was the section for troublemakers and not-so-smart kids. When I found out, I wanted to scream. I had always been a good student and had amazing friends, and now everyone thought I was a loser!
I did text my friends in Illinois almost every night, especially my best friend, Ana. At first my friends wanted to hear all about it. But then some stopped texting back once I said something about how miserable I was. One night when I was texting with Ana, I complained about another friend who had just done that.
Ana’s texts came really fast for the next few minutes and they surprised me. She said that she was tired of hearing about how bad everything was in New Jersey, too. She said she did not want to hurt my feelings but that I needed to stop feeling so sorry for myself all the time, I had to try to make things better.
The next day, I thought a lot about what Ana had said. She was right!
I wish I could say that everything changed overnight after that, but it didn’t. I was still stuck in “Loserville”, and some people were still mean to me, even though I tried to just stay out of their way.
But what did change was me—I stopped feeling so sorry for myself and did something about making friends. I signed up to make sets for the school play. I met a lot of new people there, and suddenly I had friends to say hi to in the halls!
I still miss Illinois sometimes, but life in New Jersey isn’t so hard anymore. Even though I couldn’t change my situation, I could change my attitude—and that made all the difference.
