1 . Otters, are cute, this no one can deny. They have big eyes, short and flat noses and claws (爪子) like tiny hands. They look even cuter when they wear hats and throw food balls into their mouths as if they were bar snacks, like Takechiyo, a pet otter in Japan. Documenting Takechiyo’s funny behavior has earned his owner nearly 230,000 followers on Instagram, a photo-sharing app.
Takechiyo’s fame reflects a craze across east and South-East Asia for keeping the cute creatures as pets. Enthusiasts in Japan visit cafés where they pay to hug them; Indonesian owners parade their pets around on leads or go swimming with them, then share their pictures online. But these enjoyable photos mask a trade that is doing a lot of damage. Even before they became fashionable companions for humans, Asia’s wild otters faced plenty of threats. Their habitats are disappearing. They have long been hunted for their coats, or killed by farmers who wish to prevent them consuming fishes. The pet trade, which began picking up in the early 2000s but appeared to speed up a few years ago, has made things worse. The numbers of wild Asian small-clawed otters and smooth-coated otters, two species that are in highest demand, have declined by at least 30% in the three decades to 2019.
The international agreement that governs trade in wildlife, known as CITES, now prohibits cross-border trade in these species. But laws banning ownership are often poorly implemented, as in Thailand, or full of holes, as in Indonesia. And the otter-keeping craze has been dramatically improved by the internet, says Vincent Nijman of Oxford Brookes University. In 2017 TRAFFIC, a British charity that monitors the wildlife trade, spent nearly five months looking at Facebook and other social-media sites in five South-East Asian countries. During that time, it found around 1,000 otters advertised for sale online.
In any case, otters do not even make particularly good pets. Every year the Jakarta Animal Aid Network, a charity in Indonesia’s capital, receives some ten otters from people who have struggled to look after them. Faizul Duha, the founder of an Indonesian otter-owners’ group, admits that his two animals emit a “very specific” (read: fishy) smell. They bite humans and chew on furniture. Their scream can be heard blocks away. And their cages need cleaning every two-to-three hours. That is how often they empty their bowels (肠道).

2 . The Silk Road is arguably the most famous long-distance trade route of the ancient world. This passage connected Europe in the West with China in the East, and allowed the exchange of goods, technology, and ideas between the two civilizations. Although merchants could make huge profits travelling the road, it was not without risk.
The main Silk Road started in Chang’an (known today as Xi’an), the early Han capital. Travelers commencing their journey from this city could take a northern route that would take them across China’s northwestern provinces. After this, they would face the Gobi Desert, arguably the greatest danger of the Silk Road.
The Gobi Desert, the largest desert in Asia, consists mainly of rocky, hard earth. This feature made it easier for traders to travel across, compared to sandy deserts like the neighboring Taklamakan Desert. Like other deserts, the Gobi Desert is dry and hot, and therefore the biggest challenge travelers faced was obtaining enough water for themselves as well as for their camels.
So, rest stops were created along the route, allowing travelers to rest, eat and drink. These places also promoted the exchange of goods, and even ideas, amongst the travelers who stopped there. Usually, the rest stops were placed within a day’s journey of each other. In this way, travelers could avoid spending too much time in the desert, which would make them targets for robbers, another danger of the Silk Road.
Once through the Gobi Desert, travelers would continue their journey into Iran, Turkey, and finally Europe. While this part of the journey may have been less dangerous, it is not entirely without its perils (风险).

3 . Plants cannot run or hide, so they need other strategies to avoid being eaten. Some curl up their leaves, others produce chemicals to make themselves taste bad if they sense animals drooling on them, chewing them up or laying eggs on them—all signals of an attack. New research now shows some flora can feel a plant-eating animal well before it launches an attack, letting a plant prepare a preemptive（先发制人的）defense that even works against other pest species.
When ecologist John Orrock of the University of Wisconsin-Madison sprayed snail slime—a liquid the animals release as they slide along—onto soil, nearby tomato plants appeared to notice. They increased their levels of an enzyme（酶）, which is known to prevent plant-eating animals. “None of the plants were ever actually attacked,” Orrock says. “We just gave them cues that suggested an attack was coming, and that was enough to cause big changes in their chemistry.”
Initially Orrock found this defense worked against snails; in the latest study, his team measured the slimy warning’s impact on another potential threat. The investigators found that hungry caterpillars（毛虫）, which usually eat tomato leaves greedily, had no appetite for them after the plants were exposed to snail slime and activated their chemical resistance. This nonspecific defense may be a strategy that benefits the plants by further improving their overall possibilities of survival, says Orrock, who reported the results with his colleagues in March in Oecologia.
The finding that a snail’s approach can cause a plant response that affects a different animal made Richard Karban curious, a plant communications expert, who was not involved in the study. “It is significant that the plants are responding before being damaged and that these cues are having such far-ranging effects, ” Karban says. The research was comprehensive, he adds, but he wonders how the tomato plants felt chemicals in snail slime that never actually touched them.
“That’s the million-dollar question,” Orrock says. He hopes future research will make out the mechanisms that enable plants to sense these relatively distant cues.

4 . Physical education, or PE, isn’t required for all high school students. In some schools, it isn’t offered for some different reasons. But should high school students have physical education? The answer is certainly “yes”.
Today many people don’t do sports. But as is known to all. doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult.
High school isn’t that easy. Many students are under a lot of stress. Stress can be harmful to a student’s studies and life. Doing sports can help them deal with stress better, helping them live a happier life at school.
The American Heart Association says that 10 million kids and teens suffer from obesity (肥胖). Teens should get 60 minutes of physical activity per day to control their weight and to help their bones get stronger. The increase in activities that don’t get teens to move around, such as computer games, means many teens don’t get their required exercise. PE classes act as a public health measure (措施) to encourage physical activities and help teens have healthy weights.
Not doing sports increases teens’ hazard of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 percent of health-care spending goes toward treating medical conditions that can be prevented by lifestyle changes, according to the American College of Sports Medicine.
According to the President’s Council on Fitness, Sports and Nutrition (PCFSN), students who performed five hours of physical activities each week improved their academic (学业的) performance. Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.
1. According to Paragraph 2, what does physical education in high school mean?| A．Making teens attach importance to ęxercise later. |
| B．Removing the stress faced by teens at school. |
| C．Getting teens to encourage adults to exercise. |

| A．means making students choose between sports and studies |
| B．helps students make good use of all their time |
| C．means students adjust to their studies better |
| D．helps students do better in their studies |
| A．Why high school students should receive physical education. |
| B．Why some schools consider physical education important. |
| C．How schools can help students love doing sports. |

6 . Experts believe that the best time to teach kids language skills is when they are babies. Most of the time the task is easily accomplished with parents reading or talking to their babies. However, in some cases that is not possible due to busy work schedules or when kids are born deaf. Now, an adorable blue-eyed robot, a human avatar, and some high-tech neuroscience may be able to assist parents with this important developmental task.
The Robot AVatar thermal-Enhanced system, or RAVE, is the brainchild of a team of researchers led by Laura-Ann Petitto, an educational neuroscientist, at Washington, DC's Gallaudet University. The learning process begins when the robot's camera, which is focused on the baby's face, detects tiny changes in his/her body temperature. This, combined with the baby's facial expression, causes the robot to turn its head and guide the baby's attention to a computer screen, on which a human avatar starts to communicate with the baby, much like what a parent would do. For example, if the baby points towards the screen, the avatar might respond, "Are you pointing to me?" and follow that up with a nursery rhyme, fairy tale, or some essential social communication, all in American Sign Language（ASL）. The "conversation" continues until the kid loses interest.
The researchers, who have been testing the system for three years, found that babies as young as 6 to 8 months old began to move their hands in a rhythm similar to ASL after interacting with RAVE for just a few minutes. Petitto says natural language, whether communicated through speech or sign, activates the same parts of the brain and believes the rhythmic motions prove that the babies are learning the essential elements of communication.
What sets this technique apart from other methods, such as showing educational videos or television shows, is its interactive nature and real-time response to the baby's actions. The researchers say that while it is too early to determine the system's long-term influence on baby communication, the initial response has been very encouraging. Next, they plan to introduce an avatar that can both sign and speak to babies.

7 . In America, when the eighth graders leave the middle school, they are often worried about moving to the high school. It is a hard time for them, but it can be an exciting one as well. To make it easier, students need to get familiar with their school.
Even though they’ve done this already in the middle school, it’s still important to find where their classrooms are. Most schools take students to the high school for a visit at the end of their eighth-grade year. And, most schools also have a freshman speech for parents and students before the first year begins. Sometimes the main office will give away a map of the school. This can help students and parents to find different places in the school.
One way to know your high school more and make new friends is to join a club or play a sport. Schools often offer chances to join different clubs and sports. Fall activities begin in August before the first day of school. If you are not interested in sports, there are clubs for any interest, such as drama, dance, chess, photography, community service, etc. These clubs allow students from different grades. By joining an activity, students can find new friendships, not to mention improving their chances in future college applications (申请). The school office will have a list of activities offered at the school and information on how to join them.
What’s more, to have a great start to a high school year, students can write down some of their worries, and ask for help from teachers and school workers.

10 . Being a teenager can be hard, for you have to face a lot of difficult problems, but a new program called Nfusion is working hard to help teens with mental(精神的)health needs. Nfusion gives teenagers classes where they study or discuss some troubling subjects. Drugs and bullying(欺凌)are just a few of the topics discussed during the class on Saturday.
"I had a bad attitude, " said 17-year-old Titeana Davis. Davis went through the Nfusion Program last year. The teen, who once had trouble with her attitude towards others, says the program has changed her life. "They taught me a bad attitude is not going to get you anywhere, "said Davis.
Nfusion is a new program that meets teens mental health needs and provides help for their families. The program is designed to help teens aged 14—21 live through a difficult period.
"They're still growing, still developing and still there are a lot of things they don't know how to address. So this is a good program for them to be a part of, " said Lakicha Jemigan, who worked for the Nfusion Program.
Teens like Davis are just a few who have come through the program successfully. Now thanks to Nfusion, Davis says she's looking forward to a bright future. "After I graduate from college, I want to work at a primary school and I want to be a second grade teacher, " added Davis.
