1 . Who're happier, men or women?Research shows it's a complex question and that asking whether males or females are happier isn't really that helpful, because basically, happiness is different for women and men.
Women's happiness has been declining for the past 30 years, according to recent statistics.And research shows that women are twice as likely to experience depression compared with men.Gender（性别） differences in depression are well confirmed and studies have found that biological, psychological and social factors contribute to the difference.
Early studies on gender and happiness found men and women were socialized to express different feelings.Women are more likely to express happiness, warmth and fear, which help with social bonding and appear more consistent with the traditional role as a primary caregiver, while men display more anger, pride and disrespect, which are more consistent with a protector and provider role.
Recent research suggests that these differences are not just socially, but also genetically related.Studies have looked into these findings further and discovered that females use more areas of the brain containing mirror neurons（镜像神经元）than males when they process feelings.Mirror neurons allow us to experience the world from other people's view, to understand their actions and intentions.This may explain why women can experience deeper sadness.Women tend to experience more negative feelings, such as more guilt, shame and to a lesser degree, embarrassment.
Psychologically it seems men and women differ in the way they process and express feelings.With the exception of anger, women experience feelings more strongly and share their feelings more openly with others.Studies have found in particular that women express more appreciation﹣which has been linked to greater happiness.This supports the theory that women's happiness is more dependent on relationships than men's.

2 . If all goes well, a balloonwill soon rise from Esrange Space Center in Kiruna, Sweden. It will float highinto the upper atmosphere and then return to Earth. However, environmentalists have arrived to stop this from happening.
The campaigners are against the balloon because of what occurs in flight. The balloon will shoot dust into the Earths upper atmosphere, causing more sunlight to reflect back into space. The dust, known as stratospheric aerosolinjection(SAI), is part of a solar geoengineering (地球工程) program named SCoPex which is being conducted by Harvard University. The aim of the program is to purposely change the Earth's atmosphere to fight climate change.
Those who oppose worry about two things. Firstly, the moral risk-if solar geoengineering works, talks on reducing greenhouse gases will be challenged. The second concern is the amount of SAI in the atmosphere. To keep temperatures low, the need of the reflective dust tobel released high above Earth will be endless, and a sudden stop could result in rapid warming. Raymond Pierrehumbert, a physicist at Oxford University, says solar geoengineering is even tool risky to research beyond computer models.
Not all environmentalists are opposed to it. Since the world is unlikely to achieve the 1. 5 ℃ global warming target set in the Paris Agreement, some green organizations favour small-sized geoengineering research.
Regardless of the criticism, the research continues. Geoengineering is increasingly gaining international attention. A recent report about climate change suggested that SAI could help keep warming below 1. 5℃. The National Academy of Sciences, Engineering and Medicine in the USA has developed a research plan for solar geoengineering and received governmental funding totaling $9 million. Both China and India have also launched research programmes of their own. Activists may oppose the experiments, but balloons will likely fly anyway.
1. What is the function of SAI?| A．To attract dust. | B．To throw sunlight back. |

3 . When he was two years old, Ben stopped seeing out of his left eye. His mother took him to the doctor and soon discovered he had cancer in both eyes. After possible treatments failed, doctors removed both his eyes. For Ben, vision was gone forever.
But by the time he was seven years old, he had developed a technique for feeling the world around him: he clicked with his mouth and listened for the returning echoes. This method enabled Ben to determine the locations of open doorways, people, parked cars, garbage cans, and so on. He was echolocating: bouncing his sound waves off objects in the environment and catching the reflections to build a mental model of his surroundings.
Echolocation may sound like an improbable feat for a human, but thousands of blind people have perfected this skill, just like Ben did. The event has been written about since at least the 1940s, when the word ''echolocation" was first invented in a science article titled “Echolocation by Blind Men , Bats, and Radar.”
How could blindness give rise to the amazing ability to understand the surroundings with one's ears? The answer lies in a gift on the brain; huge adaptability.
Mother Nature filled our brains with flexibility to adapt to circumstances. Just as sharp teeth and fast legs are useful for survival, so is the brain's ability to reset, which allows for learning, memory, and die ability to develop new skills.
In Ben's case, his brain's flexible wiring repurposed his visual cortex for processing sound. As a result, Ben had more neurons available to deal with listening information, and this increased processing power allowed Ben to interpret soundwaves in shocking detail. Ben's super-hearing proves a more general rule: the more brain area a particular sense has, the better it performs.
1. How did Ben “see” after he had his eyes removed?| A．By using a walking stick. | B．By asking others for help. |
| C．By inventing a new system. | D．By echolocating surroundings. |
| A．Skill. | B．Task. | C．Sense. | D．Invention. |
| A．He laughs best who laughs last. | B．Actions speak louder than words. |
| C．God shuts one door but he opens another. | D．Man becomes learned by asking questions. |
| A．Culture Shock. | B．Human Biology. |
| C．Scientific Technology. | D．Environmental Protection. |
4 . An international group of electronic music composers is taking beats from the dance club to jungles and forests and back, all to help save nature's greatest singers. A Guide to the Birdsong of Mexico, Central America and the Caribbean is a new album that includes the sounds of endangered birds. The album will come out next month, whose proceeds will go directly towards efforts to save birds.
The whole project was born out of this idea of trying to combine birdsong, electronic music and conservation. A Guide to the Birdsong of Mexico, Central America and the Caribbean was organized by activist, music producer, Robin Perkins. He invited artists from each of the endangered birds 'homelands to build their own songs around the birds’ songs. There are contributions from ten artists in eight different countries.
First single Black Catbird was created by The Garifuna Collective, from Belize. Al Obando, guitarist and producer of the group, always took in national parks and viewed birds when on the road with the band. “There are no trails, and there are no signs there to tell you about what you reseeing,” Obando says. “So we're trying to do something for the birds and nature tourism.”
Another musician who responded to Robin's call is Tamara Montenegro, an artist from Nicaragua. She was shocked to hear of the serious situation of the Guardabarranco after being approached: “This beautiful creature I grew up adoring also faced the influence of the systematic human activities”. In response, she created a song inspired by this bird and the challenges it faces to live naturally.
The new album is the second edition, following on from A Guide to the Birdsong of South America, produced by Robin in 2015. That first album has raised, to date, over $15,000 benefitting conservation projects in South America. As with the first album, all of the money from the sales of the new album will support specific organizations, including Birds Caribbean.

5 . 
Video calls are a common occurrence, but have you imagined being able to touch the person on the other end of the line? Scientists are making this a reality.
Researchers at the University of new South Wales, Australia have invented a soft skin stretch device(SSD). A haptic device that can recreate the sense of touch. Haptic technology mimics the experience of touch by stimulating localized areas of the skin in ways that are similar to what is felt in the real world, through force, vibration or motion.
Vibration is the most common haptic technology today and has been built into many electronic devices such as one attached to the back of the trackpad(触摸板) in laptops, which simulates a button clicking. However, haptic feedback with vibration becomes less sensitive when used continuously. The existing technology also has great difficulty recreating the sense of touch with objects in virtual environments or located remotely. According to Mai Thanh Thai, lead author of the study.
The new technology overcomes issues with existing haptic devices. The research team introduced a novel method to recreate the sense of touch through a soft artificial “muscles”.
“Our three-way directional skin stretch device, built into the fingertips of the wearable glove we also created is like wearing a second skin-- its soft stretchable and mimics the sense of touch-- and will enable new forms of haptic communication to enhance everyday activities”said Thanh Nho Do, senior author of the study.
Imagine you are at home and you call your friend who is in Australia. You wear a haptic glove with the SSDs, and your friends also wears a glove with integrated 3D force sensors. If your friend picks up an object, it will physically press against your friend’s fingers. And their glove with 3D force sensors will measure with interactions. The force signals can be sent to your glove so your device will generate the same 3D forces. Making you experience the same sense of touch as your friend.
The haptic devices could be applied in various situations, allowing users to feel objects inside a virtual world or at a distance. It could also be used in medical practices. Doctors can feel a patient's organ tissues. With surgical tools without touching them.

6 . Andrew Orkin was taking a break from his evening jog to sit by Prospect Park Lake when he was frightened to see a mass of snakes. They turned out to be swamp eels(黄鳝) that had escaped from one of two large plastic bags that split open as a man dragged them to the shoreline. After dumping the eels in the lake, the man walked away, explaining to bystanders that “I just want to save lives.”
The illegal release became a curiosity on social media, but the dumping of exotic(外来的) animals in urban parks isn’t new. New Yorkers free thousands of non-native animals every year. “People like animals and they sometimes think they’re doing a good thing by letting them go,” said Jason Munshi-South, an urban ecologist at Fordham University. “Most will die. Some will become a problem, and then there’s no going back.”
New York state and city officials say it’s too soon to know how the eels in Prospect Park might affect local species. The eels eat almost anything including plants, insects, frogs, turtles and other fish. And they could prey(捕食) upon or compete with the park’s native species for however long they survive.
There are no plans to eradicate the eels. Since they’re active at night and spend most of their time in the mud of lakes and rivers, spotting and removing them from the lake could be impossible. Officials say they will look for swamp eels during the agency’s next survey in the spring, but don’t expect them to make it through the winter. However, University of Toronto freshwater ecologist Nicholas Mandrak said, “Even if they don’t survive, they could have negative short-term effects.”

7 . They say everything is bigger in Texas. While that may be true, some of the best things in Texas are quite small. Case in point: tiny Mount Vernon, a town of just under 3,000 people. But if you do come across Mount Vernon, you might just get an intention to stay. That happens a lot around here, and it’s worth noting how remarkable that is.
Tom Wilkinson was born in Mount Vernon 87 years ago and moved back after he retired from his career as a college English professor in Dallas. Like many of his neighbors, Wilkinson can track his ancestors back to the pioneers who settled here in the 1870s. And like many, he values the simple life you can’t easily find in big cities. “People are still polite. They hold the door open for you.” he says, “We grow strong roots here!”
Preserving and honoring the past has been key to helping Mount Vernon survive. The residents have restored and reopened some of the empty stores, including the old barbershop, built more than 100 years ago. An old general store was turned into a combination space. Wander in on any given day and you might find a book club discussion, a Coffee Ladies meet-up, or a work session for the local genealogy(家谱) group among the tables of people chatting over cups of coffee and plates of food.
Mount Vernon has the kind of big hearts you tend to find in a small town. For instance, when a local policeman was diagnosed with cancer last year, ten-year-old Lola McKellar set up a lemonade stand to raise money for his treatments. In 2015, when a 350-year flood sent water rushing into local homes, an army of volunteers showed up to get a wheelchair-bound neighbor and his wife to higher ground, and then came back to help rebuild.

8 . Like most couples, my husband and I dreamed of becoming homeowners. Sure, apartment living comes with its own set of advantages—less housework, shared comfort, less to clean up and care for, and usually cheaper rent. As a result, we decided to downgrade from our neat five-bedroom, 2,700-square-foot house on the water to a three-bedroom, 1,369-square-foot apartment, with two kids.
Once we arrived in our new apartment, we were surprised to find that things flowed relatively smoothly. There was so much less to keep up with—fewer floors to mop, fewer windows to clean, fewer walls to wipe, etc. Now I think of our home as our little playhouse, since it's much smaller and everything is closer together. That also makes it so much easier for me to keep up with as a mom. I collect laundry all on one floor comparing with having to climb stairs to the house's second floor!
In our new home, we use lots of shoe organizers inside of every closet door for more than just shoes—baby items, office items, and medicines. We also have a functional room that serves as an office and gym. Since both my husband and I work from home, we require at least one room to share as an office with fitness equipment fitted into a corner.
While many people choose to downsize for financial reasons, that actually wasn't a factor in our decision. We wanted to be in a lively area with like-minded young families. That was our first priority. Though we may still buy another house in this area at some point down the line, for now, we're thrilled with the concept of renting an apartment. Let me put it this way: We’re not really the “handy” types, so being able to call maintenance(维修)for any repairs is worth every rent coin!
1. What can we learn from Paragraph 1?| A．Our old house was upgraded. | B．Living in a house has advantages. |
| C．Our new apartment was downsized. | D．Smaller size means more housework. |
| A．Confused. | B．Amazed. | C．Tired. | D．Challenged. |
| A．To build up their body. | B．To create a home office. |
| C．To enlarge all the rooms. | D．To make full use of space. |
| A．Transportation. | B．Neighbourhood. |
| C．Repair work. | D．Money. |
9 . Social media is taking over our lives: Facebook, Instagram, Twitter and now, TikTok. These social media platforms have transformed from a way to stay connected to an industry where even kids can make money off their posts. While this may seem like another opportunistic innovation, it’s really full of hidden false realities.
The median income (中位收入) recorded in the United States of America was about $63,000 in 2018. TikTokers can make anywhere from $50,000 to $150,000 for a TikTok brand partnership, and TikTokers with over a million followers can make up to $30,000 a month — $360,000 a year. They are making more than the average person trying to feed their family and keep a roof over their heads, simply by posting a 15-second video.
This is mad in more ways than one. Not only is it an overpaid “job”, it promotes undeserved admiration from viewers and a false sense of reality. Many of these famous TikTokers are still teens, and the effects of fame at such an early stage in life might cause issues later in life, such as mental illness. Teens between the ages of 13 and 17 make up 27% of TikTok viewers, who can be easily influenced by what they are watching. They can put a false sense of self-value into who they look up to and what they represent: money, fame, being considered conventionally attractive.
While TikTok has become a great tool for marketing, it’s important to understand how this content affects young viewers. If we’re constantly consuming content that hsows us all we need to do to be successful is be conventionally attractive and post a 15-second video featuring a new dance, it will challenge our knowledge of what really makes someone successful and will in turn affect our individual work ethics (伦理). What about the people who miss birthdays and family holidays due to their jobs and aren’t getting paid nearly as much as these TikTokers?
Richard Colyer, president and creator of Metaphor, Inc., had his own view on this issue.
“It sounds great that kids can make money for doing the latest dance moves in a 15-second video, but we should feed the minds of kids and not just their bank accounts. TikTok can be great if used properly. Money alone is not good, technology alone is not good and connectedness can be bad if it’s only online.”
Again, as a fellow consumer of TikTok, I do enjoy the app when I have some time to kill and need a good laugh. I’m not against someone making a living on entertainment, but what does getting famous of a 15-second video teach young people?
