1 . In an effort to stop poaching (偷猎) and protect endangered species, people are using technology previously created to discover stars. Claire Burke, who led the project, says the application of the starhunting tech has so far paid off big for conservation. “Since animals and humans in thermal imagery (热成像) ‘glow’ in the same way as stars in space, we have been able to combine the technical expertise of astronomers with the conservation knowledge of ecologists to develop a system to find the animals or poachers automatically,” she said in a statement.
In addition to species identification, the software can also provide an overview of health. Burke said that diseased or injured animals give off a different thermal imagery than the healthy ones. “The real advantage this gives you is that if you know how many animals you have and where they are and what kind of health they are in, then you can work out a good conservation strategy for looking after them,” she said.
The following is a post written by Burke on Twitter: More animals for the thermal imagery library. Thanks to Chester Zoo Science @ScienceatCZ for letting us observe their fantastic creatures. Images are giraffes, Indian elephants, and fruit bats.— Claire Burke (@CBurkeSci) October 27, 2017.
To train the software on a wide variety of heat signatures from different species, the team of researchers spent time collecting thermal imagery of animals. Their first field trial to detect Riverine rabbits, one of the most endangered mammals in the world (with only 500 living adults left in the wild), was a complete success. “The rabbits are very small, so we flew the drone (无人机) quite low to the ground at a height of 20 meters (65 feet). Although this limited the area we could cover with the drone, we managed to see the rabbit five times,” said Burke. “Given that there have only been about 1,000 times people have seen Riverine rabbits, it was a real success.”

2 . Asking for help is a sign of strength rather than weakness. In American culture, the independent individual is seen as their ideal. As the University of Missouri at St. Louis states on its website under the heading Key American Values, “Americans have been trained since very early in their lives to consider themselves as separate individuals who are responsible for their own situations in life and their own destinies.” The value also makes them think they can do everything themselves, and makes them feel badly about asking for help when they need it.

| A．What key American values are. |
| B．Why Americans refuse to ask for help. |
| C．Asking for help is a sign of strength. |
| D．Americans are responsible for their life. |
3 . The number of trees larger than two feet across has declined by 50 percent on more than 46, 000 square miles of California forests, the new study finds. No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles. In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts of southern California the decline was nearly 75 percent.

| B．The increasing variety of California big trees. |
| C．The distribution of big trees in California forests. |
| D．The influence of farming on big trees in California. |
4 . The creative team behind "Apes" used motion-capture (动作捕捉) technology to create digitalized animals, spending tens of millions of dollars on technology that records an actor’s performance and later processes it with computer graphics to create a final image (图像). In this case, one of a realistic-looking ape.
What does paragraph 2 mainly talk about?
| A．The cost of making "Apes." | B．The creation of digitalized apes. |
| C．The publicity about “Apes." | D．The performance of real apes. |
5 . The connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another, employees were shown to be 15% more productive when their workplaces were decorated with houseplants.
What is the first paragraph mainly about?
| A．A new study of different plants. | B．A big fall in crime rates. |
| C．Employees from various workplaces. | D．Benefits from green plants. |
6 . At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial expressions in humans. "To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions," and this exposure has provided them with many chances to learn to distinguish between them, Muller said.
What is the last paragraph mainly about?
| A．A suggestion for future studies. | B．A possible reason for the study findings. |
| C．A major limitation of the study | D．An explanation of the research method. |
7 . If you ever get the impression that your dog can "tell" whether you look content or annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human faces, according to a new study
Researchers trained a group of 11 dogs to distinguish between images（图像）of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person's face. The researchers then tested the dogs' ability to distinguish between human facial expressions by showing them the other half of the person's face on images totally different from the ones used in training. The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.
The new study focused on whether dogs can_________.
| A．distinguish shapes | B．make sense of human faces |
| C．feel happy or angry | D．communicate with each other |
8 . Popularity is a well-explored subject in social psychology. Mitch Prinstein, a professor of clinical psychology sorts the popular into two categories: the likable and the status seekers. The likables’ plays-well-with-others qualities strengthen schoolyard friendships, jump-start interpersonal skills and, when tapped early, are employed ever after in life and work. Then there’s the kind of popularity that appears in adolescence: status born of power and even dishonorable behavior.
What is the second paragraph mainly about？
| A．The classification of the popular. |
| B．The characteristics of adolescents. |
| C．The importance of interpersonal skills. |
| D．The causes of dishonorable behavior. |
9 . When almost everyone has a mobile phone, why are more than half of Australian homes still paying for a landline（座机）?
These days you’d be hard pressed to find anyone in Australia over the age of 15 who doesn’t own a mobile phone. In fact plenty of younger kids have one in their pocket. Practically everyone can make and receive calls anywhere, anytime.
What does paragraph 2 mainly tell us about mobile phones?
| A．Their target users. | B．Their wide popularity. |
| C．Their major functions. | D．Their complex design. |
10 . Independent living at home is the ideal for every aging person. But a fall or other health-threatening incidents can change everything rapidly.
The wearable “panic buttons” introduced in the late 1980s were a great advance. But they only work if people actually wear them and can reach the button in an emergency. Today there are passive wearables that automatically detect falls, and camera-based systems to monitor elder safety.
Coming from a 40-year career in the semiconductor and wireless communication field, Rafi Zack decided to find a better alternative. “People aren’t devoted to wearing small devices 24/7, and camera-based systems are an invasion（侵犯）of privacy,” he points out, “The most challenging aspect is a fall. How fast we can detect a fall matters because the medical situation worsens quickly. Sometimes people stay on the floor for a long time. We have to find out how to solve that problem.”
Zack is a co-founder, CEO and vice president of R&D at EchoCare Technologies which has developed ECHO (Elderly Care Home Observer), a cloud-connected monitor based on radar technology and machine learning.
Because radar sees through walls, one ECHO unit fixed on the ceiling or wall can monitor one person (or two persons, in a future version) in a standard-sized apartment in a senior living facility. The device detects falls, breathing difficulties, drowning in a bathtub and other dangerous events. It gives out warnings to potential health worsening conditions by continuously monitoring and analyzing the person’s location, posture（姿势）, motion and breath. EchoCare tested the device in the United States, Japan, Australia and Israel. ECHO was certified（认证）in 2019 in Japan with the most aging population in the world.
“Bathrooms were the main testing area where about 17,000 deadly accidents happen annually.” said SMK Director and Executive Vice President Tetsuo Hara. “Bathroom makers, home security service providers and nursing homes are highly interested in EchoCare’s solution.” Zack noted, “As more and more elder people live alone as a result of social distancing, there is an increased need to monitor them without the burden of wearables or privacy-invading cameras.”
