1 . A shocking news report has revealed that more than one in five species of maple trees faces extinction, warning that 75% of the threatened species are “geographically restricted” in their native regions.
The trees are experiencing a vast decline in habitat, due to urban development, wood harvesting and agricultural expansion. Time is running out for the world's biodiversity. Every recent survey of plants and animals in the wild points to this. This is happening nearly everywhere rarer maples exist. And because of climate change, the narrow habitats that support species at the edges of dry places and at the tops of mountains are quickly disappearing.
The trees can be found in subtropical and tropical regions, as far south as Indonesia. The only species found in the UK, the field maple is not under threat. Not only are the trees a popular attractive feature in parks and public spaces, but they are a key part of the natural ecosystem in woodlands, as well as being an important wood crop in several countries. Although the sugar maple in North America, which produces maple juice, is not endangered, two of the closest relatives to the species are endangered.
The report notes that conserving at-risk species in their natural habitat is the best conservation tactic. But collections in botanical gardens and seed banks-called "ex situ collections" can act as insurance policies against extinction. There are currently 14 species of maple, including four that are critically endangered, which are absent from these types of collections.
One species in Mexico, the Acer binzayedii, is in “desperate need of conservation"”despite only being discovered in 2017. “It is at risk from climate change in its cloud forest habitat and threatened by logging and forest fires while it is also absent from 'ex situ collections',” the report adds. The report recommends developing conservation plans, monitoring species currently not at risk to ensure populations are maintained, and adding those missing maple species to seed banks.

2 . Twice every month, Miranda Sam, a 66-year-old Ghanaian, visited the China Traditional Herbal Hospital, a private herbal facility at Pokuase, a suburb of the Ghanaian capital, for treatment.
“I was squeezing lemons, and when I finished, I could not get up or even move my legs, so I went to the hospital and did an X-ray examination, but they saw nothing. Meanwhile, I could not walk and was in a wheelchair,” the retired worker said. Hence Miranda decided to visit the herbal facility. “On two occasions, I had to do acupuncture(针灸), and I have found great relief. Now I walk unaided, so I keep coming for treatment,” she said.
As Traditional Chinese Medicine (TCM) is gaining popularity in Ghana, many acupuncture clinics run by Chinese doctors pop up in the country. However, the China Traditional Herbal Hospital was established by 52-year-old Ghanaian business owner Bediako, after his fruitful encounter with the effects of TCM in 2012. With the help of a Chinese lady, Bediako set up a small clinic specializing in TCM. Years on, the facility has subsequently grown into a bigger herbal hospital. The hospital treats patients with a combination of local and Chinese herbal formulas. It supports this with the application of traditional Chinese medical methods.
Strokes(中风) account for 1.3 percent of all hospital admissions in Ghana, and 6.3 percent of all hospital deaths. But Bediako is confident that as more people with these conditions turn to the natural methods of healing, the pain and death rates would subside. “A gentleman was brought here three weeks ago, who could not sit, stand, or walk. He was first taken through acupuncture. I observed him on camera 30 minutes later, squatting(蹲), standing, and walking. You come here with your pain but will leave with a smile. That is our feature,” he said.
The hospital has started a second facility in Ashaiman near the capital, with plans to open other branches across the country to meet the growing demand.

3 . A sleepover (过夜) program, which is designed to make kids believe that their favorite toys enjoy reading, can help encourage children to pick up more books, a new study suggests.
Toys sleepover programs are designed to get children interested in books. Children take their toys to a library for the night. At this point, workers and volunteers take photos of the toys which explore the library and read books. The next day, the children collect their toys and the photos of what the toys did during the night. They are given the books their toys chose to read.
It was found that before the sleepover the children did not spend time looking at the books in their play area at preschool. Immediately after the sleepover, the number of children who read to the toys was higher than the number who did not, but after three days the effect decreased gradually.
The researchers also tested a method for sustaining the effect. They reminded the children of the sleepover a month later, by hiding the toys and showing them the photos again the next day. This simple method brought an increase in the number of children reading to their toys.
The study proves for the first time that children who take part in sleepover programs read picture books to their toys more. “We wanted to know if there really was an effect, and if so, how long it lasts. Surprisingly, not only did the children show interest in the books, but they also began to read to their toys. This means that a new behavior pattern appeared that the children hadn’t had before. We did not expect anything like this,” said one of the researchers.
Reading is important for the development of children’s language skills and imagination. When parents read to their children, it is a passive way of reading for the child. However, when children read to their toys, it is a more active, self-directed way of reading, helping them develop into more active readers, researchers said.

4 . Perhaps you have ever heard the saying: Change is the only constant. Everyone, without doubt, goes through changes in their life, whether it is a physical state of aging or a mental state of emotional maturity. However, some are afraid to make the conscious decision to move or they think it's too late to have a fresh start.
I have a friend named Jack. At the age of 37, he is a Senior Manager at one of the Big Four. He has a great salary, owns his own apartment and enjoys the fine things in life, but not without the heavy burdens that his job brings. On the surface, it looks like he has got life figured out. Yet when I once asked if he was happy with his work, he answered that he some- times wished to quit his job to do something less stressful. But he’d become accustomed to this lifestyle and felt that it would be too late to give it up to achieve a new ambition.
For him, the risks are too high, so whether he can't abide his present job or not, he has to choose to suck it up. You might have come to a similar situation as Jack’s or you might be a Jack. You're now facing a wall. No matter what it is—the stress of your job or the terrible feeling, it’s time that you had to decide whether you'll tear down that wall or continue to let it enclose you. I suggest pushing back the boundaries and breaking the fixed patterns. Why do you feel it's too late to start over? That is simply because you're comparing yourself with others—younger or more successful individuals. In fact, you should compare yourself with the older version of you.
Don't become that person who lets life pass by only to regret it when you are making your way into old age. Don't let your life plateau（停滞不前）and waste away in the daily chores. Don't give up the potential you still have hidden and be locked away by your current state. Now, you’d better bravely start going after the things you want to do, without abandoning your dreams, ambitions and responsibilities.
1. What kind of people does Jack represent according to the author?| A．Those leading a happy life. |
| B．Those having an easeful career. |
| C．Those thinking it's too late to change. |
| D．Those having a high ambition to work. |
| A．Value. | B．Recommend. | C．Understand. | D．Tolerate. |
| A．Let life stand still. |
| B．Enjoy the present job. |
| C．Have a small goal in life. |
| D．Consider ourselves as a failure. |
| A．Everyone Can Meet a Jack |
| B．Don't Try to Control Yourself |
| C．Never Think Change Is Too Late |
| D．You Should Make Alteration Earlier |
5 . Imagine a world where you move around in front of a personal computer in your own sound space. You listen to your favorite songs, play loud computer games or watch a movie — all without other people hearing the sound and without headphones.
That is the possibility presented by “sound beaming”, a new technology from Noveto Systems, an Israeli company. On Friday, the company introduced a desktop device that sends sound directly to a listener without the need for headphones or a special receiver.
Noveto Systems gave The Associated Press (AP) a chance to test its SoundBeamer 1.0 before its introduction. The AP’s Louise Dixon writes that listening to the device is like something from a science fiction movie.The sound seems so close that it feels like it is inside your ears while also in front, above and behind them.
Noveto expects the device will have many uses. Office workers could listen to music or conference calls without others hearing. People could play a game, a movie or music without waking up others in the same room. Because the device does not use headphones, it is possible to hear other sounds in the room clearly.
The device uses a 3-D sensing module that finds and follows the ear position of the listener. It sends ultrasonic waves (超声波) to create sound pockets by the user’s ears. The 3-D method creates sound on all sides of the listener, therefore the listeners feel completely transported into the scene.
By changing a setting, the sound can follow a listener around when he moves his head. It is also possible to move out of the sound beam's path and hear nothing at all.
While the idea of sound beaming is not new, Noveto was the first to launch the technology.
According to the chief executive officer Christophe Ramstein, a “smaller” version of the device will be ready for release to consumers next year.

6 . SHOULD WE FIGHT NEW TECHNOLOGY?
This morning, I saw the shocking headline: “Passenger Dies When Car Crashes in Driverless Mode”.In the article, a lot of people said that the public should oppose the idea of developing driverless cars.They said that some advances in technology were unnecessary and could even be dangerous.Hence, we should cease accepting technology just because it is new.The newspaper reported that the car company had already apologized for the accident, but the families of the deceased said it was not enough.Nevertheless, the company still claimed that most people would be travelling in driverless cars one day soon.
On the one hand, there are many different groups of people around the world who live happily in the absence of new technology.Probably the most well known are the Amish, a group of Christians living in rural America.They do not own or drive cars, watch TV, or use the Internet.They have lived mainly as farmers since the 18th century, and they will probably be living the same way in the distant future.They advocate a simple life with an emphasis on hard work, family, and community.They think that is better than caring about luxuries or following the lives of the rich and famous.It could even be argued that the Amish’s quality of life is better since they live in and appreciate the natural environment rather than living in large, polluted cities.
On the other hand, new technology has provided people everywhere with many benefits over the years.For example, the latest weather-tracking computer programs give people lots of warnings about potential natural disasters, which saves many lives.Moreover, the Internet has made it possible for friends and family to keep in touch easily even if they are on opposite sides of the world.It has also made finding opportunities in life much easier, as it allows people to make larger networks of friends through using social media.
Personally, I have benefited quite a lot from technological advances.I found my career as an AI designer through a social media network.My health monitor, which I wear all the time, has also helped me get into the best shape of my life.Of course, when new technology changes the way we live, it can be a scary prospect.Nevertheless, I will always look on the positive side of change and accept it rather than resist it.

7 . Setting goals is common in our life. We look ahead, predict what may make us happy in the future, and then narrow down the things to something specific. For the most part, having goals is better than not having any, but there are also problems that come with spending an entire life living from goal to goal.
For one thing, we try to predict an unpredictable future. Who is to say that what you want next year is the same thing you want right now? What if what you want right now isn't in the right direction over the long term?
Secondly, and just as importantly, you only confine your expectations of happiness and satisfaction to the goal you have set so that you often forget that other things in your life can also add just as much joy to your experience. This creates a strange problem.
To solve this problem, we have to move towards something more unclear. Going after interestingness. I think, is what we should do.
Interestingness doesn't mean looking for pleasure only. It’s deeper than that. It's doing that random (随机的) project you had no plan to do because you have a feeling that you might just learn something you didn't know about yourself. It's seeing a person you just met not as a possible partner or someone who can do something for you but simply as someone who may open a new, unknown and unique world for you.
Goals incorrectly assume (假设) that we already know what we want. Interestingness is more modest. It makes up its mind as it moves, slowly blowing from one thing to another, until it catches something that lies beyond prediction at last.

| B．To express a new thought on setting goals. |
| C．To point out disadvantages of an aimless life. |
| D．To recommend a new way of achieving success. |
8 . Declining mental function is widely regarded as a problem of old age, but certain aspects of brain function actually begin their decline in young adulthood, a new study suggests.
The study, which followed more than 2,000 healthy adults between the ages of 18 and 60, found that certain mental functions—including measures of abstract reasoning, mental speed and puzzle-solving—started to dull as early as age 27. The dip in memory, meanwhile, generally became apparent around age 37.
On the other hand, indicators of a person’s accumulated knowledge—like performance on tests of vocabulary—kept improving with age, according to the findings.
The results do not mean that young adults need to start worrying about their memories. Most people’s minds function at a high level even in their later years, according to researcher Timothy Salthouse.
“These patterns suggest that some types of mental flexibility decrease relatively early in adulthood, but that the knowledge one has, and the effectiveness of integrating (整合) it with one’s abilities, may increase throughout all of adulthood if there are no diseases,” Salthouse said.
The study included healthy, educated adults who took standard tests of memory and reasoning over a period of seven years. In general, Salthouse and his colleagues found, certain aspects of cognition (认知能力) generally started to decline in the late 20s to 30s.
The findings threw light on normal age-related changes in mental function, which could aid in understanding the process of dementia (痴呆). “By following individuals over time,” Salthouse said, “we gain insight in cognition changes, and may possibly discover ways to slow the rate of decline.”
The researchers are currently analyzing the study participants’ health and lifestyle to see which factors might influence age-related cognitive changes.

9 . A modern phone can put the world at the user’s fingertips. Calls, messaging, photos and information access, all make for a better lifestyle. But sometimes, these phones are of little practical use. Leku Wuniure’s 63-year-old mother communicates in the Yi language, because she can’t read Chinese or speak Mandarin and is even unable to read numbers. As a result, a very simple, taken-for-granted feature of any modern phone like finding someone, can prove to be difficult. Whenever she wants to call her son, she has to ask someone to help her to dial his number.
Leku, 25, a young man of the Yi ethnic (彝族) group, naturally, wanted to help. So he created an app that responds to his mother’s request to “call my son” in the Yi language. Once this is said, the app will automatically dial his number. The app is called Yayou. It turned out to be a fantastic aid for his mother and has also benefited many among the more than 8 million Yi people in China.
“With the app, I wanted to help my mom, as well as the Yi people,” says Leku, a college student at Chongqing University. “Besides my mother’s plight, I’ve also witnessed some villagers, who left to make a living as workers in cities, suffering financial losses or misunderstanding due to the obstacles (障碍) in communication.”
The dream is becoming bigger-after more than two years’ development, Leku and his partner Mise Achang are ready to launch an updated version of their app in May. The 2.0 version of Yayou will have several new functions, providing news and entertainment content, as well as online shopping services, in both the Yi and Chinese languages. What’s more exciting, some users will be able to test the new voice assistant function and interact with their smartphone in the Yi language, before its final release.
With the app, users could listen to more songs, watch videos and read news presented on the app in the Yi language. The app, apart from bringing greater convenience, can also serve as an important cultural tool. It can be used as a database to collect oral and written records of Yi culture and help keep it.
1. What makes it hard for Leku’s Mother to ring him up?| A．New technology. | B．Language difficulty. | C．Her old age. | D．The complex number. |
| A．Understanding. | B．Impression. | C．Trouble. | D．Request. |
| A．App Helps Ring in a Better Life | B．Mother’s Request Is Satisfied |
| C．A Practical App for Cellphone | D．A Clever Son and His Mother |
10 . Regrets are often painful. A study suggests that some people can overcome them, said Jia Wei Zhang, a psychology graduate at the University of California. But this isn’t the case for everyone, he said.
The researchers wondered why some people report feeling improvement from regrets but others don’t. Does it lie in how people approach their regrets?
In the study, the researchers focused on self-compassion (自我同情) as a potential factor in why some people have an easier time leaving their regrets behind them.
400 people attended an experiment. First, they were asked to write about their biggest regret. Half wrote something they did but wish they hadn’t done; the other half wrote something they didn’t do but wish they had. Then, the participants were randomly assigned to one of three groups: self compassion, self-esteem and a control group. The self-esteem group was asked to respond by “talking to yourself about this regret from the aspect of confirming your positive qualities”.
The control group was asked to write about their favorite hobby rather than their regret. Then, they were asked about their feelings of forgiveness, acceptance and personal improvement following the exercise.
They found that the self-compassion group reported greater feelings of acceptance, forgiveness and personal improvement, compared with the control group and the self esteem group. In other words, focusing on your best qualities is not what helps you feel better about a regret. Rather, being compassionate toward yourself is what may make a difference, the researchers found.
It’s possible that people who practice self-compassion are able to confront their regrets and see what went wrong, so they can make a better choice in the future, Zhang told Live Science. Self-compassion pushes people to accept their regret instead of running away from it.
The researchers used an example of this from a previous study on breast cancer patients who were asked to try thinking about their treatment in a positive light before it began. The women who did so reported greater feelings of personal growth later on.
