Every minute, people around the world purchase 1 million plastic bottles,1.adds up to roughly 526 billion bottles every year. Much of the plastic2.(end) up in landfills (填埋场), rivers or oceans, often with destructive effects on wildlife. Many people are now trying to cut down on plastic use, while also turning the single-use plastic into something3.(use) — like auto parts.
Recycles plastic is ideal for automotive parts due to its light4.(weigh) that offers additional benefits such as5.(improve) a vehicle’s aerodynamics (空气动力) and reducing cabin noise.
The use of plastic in vehicle parts has grown a lot since the last decade, especially in underbody shields (车底护板).6.is assumed that around 1.2 billion recycled plastic bottles are used every year — that’s about 250 bottles per vehicle7.average.
How exactly does your plastic water bottle turn into an aerodynamic auto part? After you put the bottle into the recycling bin, it’s8.(eventual) combined with thousands of others and cut into tiny pieces. Then, these pieces9.(sell) to a supplier, who turns them into a fiber by melting them. This fibers mixed with other elements (元素) in a special process, and then were used 10.(create) a sheet of material that can be formed into vehicle parts.

Whether you’d like to loosen tight muscles, become more flexible, or just keep yourself tom getting injured when you exercise or play sports, stretching is important. With just a few minutes of gentle stretching, you can reduce the pain that comes from tight muscles, improve your posture, and increase your range of motion.1.With all these benefits, why not give stretching a try?
1. Hamstring (脚筋) (or Back-of-the-leg) Stretch
The hamstring muscle runs down the back of your upper leg. Tightness in this muscle can lead to serious back pain, so its an important one to stretch.2.Working one leg at a time, lift your leg and rest the heel on the wall with your leg slightly bent. Gently straighten your leg until you feel a nice stretch. Pause there and wait. Then switch legs.
2. 3.
Tight shoulder muscles can lead to neck and back pain as well as other problems. It’s important to keep these muscles flexible. You can raise straight overhead, then bend the elbow so that your right hand falls behind your head. Using your left hand, gently pull your right elbow toward the centerline of your body. Ideally, you want your right forearm to be straight up and town. Be sure to keep your head and neck straight, and don't let your right arm force the head down or forward in any way.4.
3. Neck Stretch
This is very important for drivers! Stretch your neck one side at a time, beginning with the right. Tip your hear to the left.5.Do not pull hard. The neck is fragile, so you must be gentle with this stretch. Repeat on the opposite side.
A.Arm Stretch.
B.Shoulder Stretch
C.Switch arms and repeat.
D.Stand about an arm’s length away form a table.
E.Stretching also improves your balance and coordination.
F.For a gentle stretch, lie on the for near a doorway or wall comer.
G.And use your left hand to very gently pull your head toward the front of your left shoulder.
Nail biting and hair pulling are two forms of body language. Both nail biting and hair pulling can be either conscious or subconscious body language gestures, each showing some interesting aspects of the character, emotion and inner working of the individual.
Nail biting is a non-verbal gesture. In adults it’s often a habit adopted and carried through from childhood and can become apparent in stressful situations throughout adulthood. To most people, nail biting is associated with nervousness and shyness and is an involuntary response to certain social situations. In many cases, it’s an adaptor behaviour that channels nervous energy, inactivity or boredom and doesn’t disturb normal functioning. In severe cases nail biting can become a repetitive behaviour that is intentionally performed. It can result in great physical damage.
So when we look deeper, in both adults and children, it has been suggested that severe nail biting is often referred to as a method of “self-heating”. This indicates that nail biting is a subconscious behaviour indicating increased anxiety and low self-confidence.
Hair pulling can indicate a number of emotions and behaviors. For example, children who bite their nails or frequently pull their hair may be nervous or have low self-confidence. Hair pulling may be a comforting action for a child who is tense and anxious, and may become habitual later in life in stressful situations. Routine and severe hair pulling can be a compulsive disorder that may be linked to genetics, anxiety and depression. It’s most commonly thought to be a stress-related condition.
However, hair puling is also another non-verbal body language that can signify different things in different situations. For example, in some situations, it can mean interest and desire. However, in other situations, it can suggest anxiety, incompetence, uncertainty or shyness.

Scientists at the University of Oxford have developed new artificial intelligence (AI) software to recognize and follow up the faces of individual chimpanzees (黑猩猩) in the wild. The new software will allow researcher and wildlife conservationists to greatly cut back on time spent analyzing videos, according to the new paper published today in Science Advances.
“For species like chimpanzees, which have complex social lives and live for many years, getting photos of their behavior from short-term field research can only tell us so much.” says Dan Sehofield, researcher and DPhil student at Oxford University’s Primate Models Lab, School of Anthropology. “By taking advantage of the power of machine learning to unlock large video files, it makes it possible to measure behavior over the long term.”
The computers model was trained using over 10 million images (影像) from Kyoto University’s Primate Research Institute (PRI) video files of wild chimpanzees in Guinea, West Africa. The new software is the first to continuously track and recognize individuals in a wide range of posed, performing with high accuracy in difficult conditions such as low lighting and poor image quality.
“Access to this large video file has allowed us to use the newest deep neural networks to train models at a scale that was previously not possible,” says Arsha Nagrani, co-author of the study and DPhil student at the Department of Engineering Science, University of Oxford. “Additionally, our new software differs from previous primate face recognition software in that it can be applied to raw videos with limited manual intervention (人工干预) or pre-processing, saving hours of time.”
The technology has potential for many uses, such as monitoring species for conservation. Although the present application focused on chimpanzees, the software provided could be applied to other species, and help drive the adoption of AI systems to solve a range of problems in the wildlife sciences.
1.What’s the purpose of developing the new software?
A.To save wildlife researchers’ time spent in the wild.
B.To keep track of wildlife conservationists’ behavior.
C.To protect chimpanzees and help them to live longer.
D.To recognize and track the faces of wild chimpanzees.
2.What does the underlined word “it” in paragraph 2 refer to?
A.Getting photos. B.Analyzing videos.
C.The new AI software. D.A powerful machine.
3.What does paragraph 4 mainly talk about?
A.The unique advantages of the new software.
B.Some limitations of using the new software.
C.The working principles of the new software.
D.Controversial attitudes to the new software.
4.What can be inferred from the last paragraph?
A.The new software has a quite bright future.
B.The application of the technology can be tough.
C.Technology is the final goal of scientific research.
D.AI systems are widely used in the wildlife sciences.
It’s not every day that you see pigeons(鸽子)with cowboy hats on their tiny heads walking or flying around, unless you live in Las Vegas, where cowboy-hat-wearing pigeons are actually a thing people have been constantly taking about these days.
It all started on December 5, when a Las Vegas citizen named Bobby Lee noticed two funny-looking birds walking near a dustbin. The pigeons drew his attention because they were wearing tiny cowboy hats — one red and one grey — so he took out his smartphone and started filming them. Later, he uploaded the video online, where is quickly spread. The next day, everyone was talking about Las Vegas’ cowboy-hat-wearing pigeons, and Lee was getting phone calls from agencies trying to license his video.
It was only a matter of time before news outlets picked up the story and reported on the mysterious pigeon cowboys spotted around Las Vegas. The only link anyone could think of was the Wrangler National Rodeo Finals that were taking place in town at the time, but the Professional Rodeo Cowboys Association, which organized the event, denied any involvement.
While some netizens just found the idea cute and jumped at the opportunity to catch the pigeons on camera if they spotted them around Vegas, others expressed concern about the birds’ well-being. They even mentioned animal cruelty.
Hillman, the founder of local pigeon rescue Lofty Hopes, said that her organization was trying to track down the birds and remove their hats, but trapping them with food has proven very difficult so far. That’s because the two known cowboy-hat-wearing pigeons have become very popular around Las Vegas, and people are constantly throwing them much food.
“When you see them today, you could see some loose feathers in the glue around the hat, and it’s surely a concern,” Hillman said, adding that she believed the hats had been glued on with a strong adhesive (粘合剂).
1.What has been a hot topic in Las Vegas recently?
A.The return of cowboy hats. B.Pigeons approaching people.
C.Pigeons wearing cowboy hats. D.The hobby of watching pigeons.
2.What made Bobby Lee film the two pigeons with his smartphone?
A.Their unusual decorations. B.Their unique feather colors.
C.Their great popularity online. D.Their strange way of walking.
3.What was netizens’ attitude towards the pigeon cowboys?
A.They went too far about them. B.They thought nothing of them.
C.They showed little interest in them. D.They had a mixed response to them.
4.Why is it hard to trap the two pigeons with food?
A.Because they are rather particular about food.
B.Because they always have abundant food to eat.
C.Because they are smart enough not to be tricked.
D.Because they are well protected by pigeon watchers.
