1 . With the social media freely available, I've realized how easy it is to become a jealous cow. The truth is that however much I remind myself of the many wonderful things I have in my life, there are still moments when I look at those around me and feel bitterly upset by their success.
It's a horrible thing to admit! In an ideal world, I'd never want to be jealous of another person's achievements and I'd want to celebrate the successes of my friends. But sometimes it's hard, even when we want to. But I don't want to live my life as a jealous cow, and I assume you don't either.
It's easier to celebrate other people's wins if you celebrate your own. How often do we take the time to enjoy our success rather than instantly move onto the next thing we want to achieve? Last year, I decided to write a book. It was the only professional goal I set for myself and, while it tired me out, I got there. But as soon as it was done, I started planning my next goal-making the book a success. As I saw other people publishing books, I stopped celebrating and instead began to fear that mine wouldn't compete.
When I told a friend how I was feeling, she reminded me how much easier it is to clap for someone else when we also clap for ourselves. So, I took myself out for lunch, ordered a glass of wine and wrote myself a congratulations card. When I saw all those other books being written on my social media, I felt proud of each and every one of us who had battled to the end of the word count.
The other trick for celebrating other people's success is to realize that there is no limit on success. We can make more, which means that while it might seem as if others have everything and we have nothing, the reality is that life turns quickly and our luck could change at any time. If others have achieved those things, we can too. When we celebrate others, we're acknowledging their achievements but also cheering for ourselves as well as for our hopes and dreams and our belief that we can make them happen. And hopefully, when we do, those people will cheer for us too.

2 . With the world’s attention on vaccines (疫苗), now feels like a good moment to sing the praises of an often forgotten contribution to their development. Three hundred years ago this month, Lady Mary Wortley Montagu got her daughter inoculated (接种) against smallpox, making her child the first person in the West to be protected in this way. Without Montagu’s willingness to adopt a practice she had learned from other cultures, the introduction of vaccines around 80 years later would never have taken place.
Montagu first witnessed inoculation when she accompanied her husband to Turkey in 1717. Inoculation had started in Asia, probably in China, as early as the 10th century AD. Montagu observed how older women in Turkey took a tiny amount of pus (脓) from a person with smallpox. They then used needles to make cuts on people’s wrists and ankles and added the pus to their bloodstream. This helped people gain immunity from future infection.
Like other visitors to the country, Montagu took steps to ensure that her son was inoculated in Turkey. This worked well, but she knew that trying it in England would be far more challenging. Inoculation performed by unlicensed amateurs would threaten doctors’ professional standing and potentially rob them of valuable income. Churchmen also disagree with the practice, as they saw it as going against nature.
Back in England, Montagu observed the increased severity of smallpox infections. Eventually, in April 1721, she decided to use the Turkish practice to have her daughter inoculated, because she believed that the rewards would outweigh the risks. After a safe time had passed following the inoculation, Montagu allowed doctors to examine her daughter.
Doctors in Britain gradually accepted the practice. About so years later, a pioneering physician found smallpox vaccines to destroy smallpox completely. As early as last century, academics argued that Montagu was no more than an enthusiastic amateur. In truth, she made a vital scientific contribution towards finding the cure for smallpox.

In Africa, the honeyguide birds can respond to human calls to lead people to honey—what scientists describe as a mutualistic interaction, or one that benefits both creatures. The birds tweet and fly from tree to tree to guide honey seekers to hidden bee nests, typically inside trees. Then, humans open the trees to find honey, and the birds can dine on beeswax, their favorite food. |  |
Dogs have an excellent sense of smell, which is why the folks at Penn Vet Working Dog Center are training dogs to identify the smell of cancer using tissue and blood samples from people who suffer. The scientists hope to develop a way for dogs to screen samples first, then perform follow-up testing on the samples the dogs flagged—a system for spotting cancer in its early stages. |  |
Having a snake wrapped around your neck isn’t necessarily what you usually expect. But Monty, a 13-year-old snake has been helping customers relax with neck massages(按摩). It’s unlikely he was trained to do the job and is just pulsating like any other snake would when around a person’s neck. Regardless, this special snake books out a few weeks in advance. |  |
The Guide Horse Foundation has been training miniature horses (those standing 34 inches or less) as assistance animals for the visually damaged since 1999. Miniature horses are ideal service animals for people who feel uncomfortable with dogs or who want a guide animal with a longer life span. The horses typically live from 30 to 40 years. |  |

4 . If you've ever watched Planet Earth, you know the ocean is a wild place to live. The water is full of different ecosystems and organisms varying in complexity from an erudite octopus to a sea star. Unexpectedly, it is the sea star, a simple organism characterized by a decentralized (分散的) nervous system, that offers insights into advanced adaptation to hydrodynamic forces — the forces created by water pressure and flow.
Researchers found that sea stars effectively stay attached to surfaces under extreme hydrodynamic loads by altering their shape. Sea stars create a "downforce" due to their shape. This mean that instead of being lifted by the flow forces, the sea stars are pushed downward toward the rock or floor surface they are on.
"Sea stars are incredibly adaptive," said Luhar, assistant professor. “When there is high wave activity and high water forces, sea stars will grow skinnier and take on a lower profile (姿态). When the sea star is transported to a sheltered environment with lower hydrodynamic forces, they pop up a bit and their cross sections get bigger."
Understanding such shape shifting could help design underwater robots that can similarly adapt to extreme hydrodynamic environments, Luhar said.
The researchers tested this understanding of sea star shape and its impact on force in the water with both computational and 3-D printed models. “Right away what we noticed," Luhar said, "is that instead of the sea stars being pulled away from the surfaces they were on, they were being pushed down- simply because of their shape."
Luhar said the researchers saw this downforce effect as key to how the sea star- and in the future, an underwater robot could stay attched to a sea bed or a rock as opposed to being lifted up away from it, even in the most extreme conditions.

6 . Light pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.
Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial light at night — in combination with habitat loss, chemical pollution.invasive (入侵的) species, and climate change — is driving insect declines, " the scientists concluded after assessing more than 150 studies.
Insect population collapses have been reported around the world, and the first global scientific review published in February, said widespread declines threatened to cause a "catastrophic collapse of nature's ecosystems".
There are thought to be millions of insect species, most still unknown to science, and about half are active at night. Those active in the day may also be disturbed by light at night when they are at rest.
The most familiar impact of light pollution is moths (飞蛾) flapping around a bulb, mistaking it for the moon. Some insects use the polarisation of light to find the water they need to breed, as light waves line up after reflecting from a smooth surface. But artificial light can scupper (使泡汤) this. Insects are important prey (猎物) for many species, but light pollution can tip the balance in favour of the predator if it traps insects around lights. Such increases in predation risk were likely to cause the rapid extinction of affected species, the researchers said.
The researchers said most human-caused threats to insects have analogues in nature, such as climate change and invasive species. But light pollution is particularly hard for insects to deal with.
However, unlike other drivers of decline, light pollution is relatively easy to prevent. Simply turning off lights that are not needed is the most obvious action, he said, while making lights motion-activated also cuts light pollution. Shading lights so only the area needed is lit up is important. It is the same with avoiding blue-white lights, which interfere with daily rhythms. LED lights also offer hope as they can be easily tuned to avoid harmful colours and flicker rates.

7 . An 85-year-old primary school constructed in 1935 in Shanghai has been lifted off the ground in its entirety and relocated using new technology called the “walking machine.” The project marks the first time this “walking machine” method has been used in Shanghai to relocate a historical building.
Urbanization（都市化）has continued to significantly threaten architectural heritage. In the capital Beijing, for instance, more than 1,000 acres of its historic hutongs and traditional courtyard homes were destroyed between 1990 and 2010.
In the early 2000s, cities including Nanjing and Bejjing-due to the critics’ protest about the loss of old neighborhoods-drew up long-term plans to preserve what was left of their historic sites, with protections introduced to safeguard buildings and restrict developers.
These conservation efforts have taken different forms. In Beijing, a near-ruined temple was transformed into a restaurant and gallery, while in Nanjing, a cinema from the 1930s was restored to its original form, with some additions providing it for modern use. In 2019, Shanghai welcomed Tank Shanghai, an arts center built in renovated（重修的）oil tanks.
“Relocation is not the first choice, but better than destroying,” said Lan, the Shanghai primary school’s project supervisor. “I’d rather not touch the historical buildings at all.” Building relocations he said however, are “a workable option.” “The central government is putting more emphasis on the protection of historical buildings. I’m happy to see that progress in recent years.”
Shanghai has arguably been China’s most progressive city when it comes to heritage preservation. The survival of a number of 1930s buildings and 19th-century “shikumen” （or “stone gate”） house have offered examples of how to give old buildings new life.
“We have to preserve the historical building no matter what, ” Lan said. “The relocation has challenges, but in general, it is cheaper than destroying and then rebuilding something in a new location.”

8 . Full stops intimidate young people when used in social media communication as they are interpreted as a sign of anger, according to linguistic experts.
Teenagers and those in their early twenties, classified as Generation Z, have grown up with smartphones which they use to send short messages without full stops. Linguistic experts are now investigating why teens interpret a correctly-punctuated text as a signal of annoyance.
The debate became active again after writer Rhiannon Cosslett tweeted: “Older people, do you realise that ending a sentence with a full stop conies across as sort of abrupt and unfriendly to younger people in a message?” Genuinely curious. That caused crime novelist Sophie Hannah to reply: “Just asked 16-year-old son — apparently this is true. If he got a message with full stops at the end of sentences? He’d think the sender was weird, mean or too blunt.”
According to experts, youngsters used to communicating electronically break up their thoughts by sending each one as a separate message, rather than using a full stop, which they use only to signal they are annoyed. Some have said the full stop is unnecessary when used in texting because the message is ended just by sending it.
Linguist Dr Lauren Fonteyn of Leiden University in Holland tweeted: “If you send a text message without a full stop, it’s already obvious that you've concluded the message. So if you add that additional marker for completion, they will read something into it and it tends to be a falling intonation (语调) or negative tone. Make your sentence an open end. and it will make friends online very happy and relaxed. So full stops could be unnecessary in most cases.”
Professor David Crystal? one of the world’s leading language experts, argues that the usage of full stops is being “revised in a really fundamental way”. In his book, Making a Point, he says that the punctuation mark has become an “emotion marker” which warns the recipient (接受者) that the sender is angry or annoyed.
1. What does the underlined word “intimidate” probably mean in paragraph 1?| A．Frighten. | B．Move. | C．Delight. | D．Reward. |
| A．Full stops end the conversation awkwardly. |
| B．Full stops make messages more boring. |
| C．Full stops are punctuation marks without any emotion. |
| D．Full stops are regarded as an indication of the sender's anger. |
| A．Skeptical. | B．Conservative. | C．Negative. | D．Tolerant. |
| A．Will full stops be replaced in messages? |
| B．Does a full stop really conclude a message? |
| C．How do full stops make recipients embarrassed? |
| D．How do we understand punctuation marks in messages? |
9 . Not long ago, Linda Khan was sitting by a hospital bed in Houston, feeling ill at ease. Beside her lay her father who needed a heart surgery. The two of them had engaged in nothing but depressing small talk. Then, her eye fell on a pile of books. She picked up one, and started to read it out loud. "Right away it changed the mood and atmosphere," she says. Reading gave the daughter a way to connect with her father. Listening allowed the father travel on the sound of his daughter's voice into a place where he felt himself again. “From then on," Khan says, “I always read to him."
In a 2010 survey in the United Kingdom, elderly adults who joined weekly read-aloud groups reported better concentration, less anxiety, and an improved ability to socialize. The survey authors owed these improvements in large part to the “rich, varied diet of serious literature" that group members consumed, with fiction encouraging feelings of relaxation and calm, poetry fostering focused concentration, and narratives giving rise to cognitive (认知的) thoughts, feelings, and memories. In truth, almost any kind of reading to another person can be beneficial.
Readers get rewards too. For Neil Bush, the late-life hospitalizations of his famous parents, George H. W. and Barbara Bush, became opportunities to repay a debt of gratitude. “When I was a kid, they would read to me," he said. With his parents in and out of care, “We've been reading books about Dad's foreign policy and, more recently, Mom's autobiography." Bush went on, his voice thick with emotion, “And to read their amazing life to them has been a remarkable blessing to me, personally, as their son."
To many people, reading to parents may seem so far outside the normal range of regular activities, and it may even feel odd and improper. However, there are still a lot many who brave the momentary strangeness of reading to elderly adults and both reader and listeners are, to borrow a phrase from Wordsworth, surprised by the joy of it.

| C．Children should show their gratitude. |
| D．Reading to parents is children's duty |
| A．Improper and odd. | B．Abnormal but worthy. |
| C．Rewarding and joyful. | D．Interesting but unnecessary. |
10 . Ian McKenna was in third grade when he learned that many kids at his Austin school weren't getting enough to eat at home. He wanted to help, but local volunteer organizations turned him away, saying he was too young. So he decided to find his own solution. For years, he had been gardening with his mother, and they often distributed their extra vegetables to the neighbors. “Why not give the produce to a soup kitchen? Then I thought, I'm good at gardening," says McKenna, now 16. “Why not plant a garden at school, so that kids in need could take food home?"
McKenna persuaded his school to set aside space for a garden; then he asked the community for donations of seeds and equipment. Other students donated their time. Within months, McKenna's garden was producing lettuces, tomatoes, cucumbers and squash for students and their families. Now, seven years later, McKenna's Giving Garden project has expanded to five area schools in addition to his own backyard garden, and he has provided organic produce, enough for 25,000 meals, to Austin families.
For most of his gardening activities, McKenna wears the same T-shirt in different colors, with his personal motto on it: BE A GOOD HUMAN. To him, that means helping in any way you can, no matter what your age. "Even a smile might change someone's life," he says. “It lets them know that they are important. It can make their day."
When COVID-19 hit the U.S., McKenna redoubled his efforts, cooking up to 100 meals to distribute to the hungry on the weekends. When social distancing meant that volunteers couldn't work on community garden plots, he started offering online classes and a gardening hotline so families could grow at home. While gardening is his core focus, McKenna says he is always looking for new ways to help the hungry.
