There is a popular saying in the English language: “Sticks and stones may break my bones, but words will never hurt me.” Well, that is not true. Unlike words, name-calling or even the so-called “the silent treatment” can hurt children as much as being physically hit, sometimes even more so.
A recent study of middle school children showed that verbal (言语的) abuse by other children can harm development in the brain. The study was a project of researchers at Harvard Medical School in Massachusetts. Researcher Martin Teicher and his team studied young adults, aged 18 to 25. These young men and women had not ever been treated in a cruel or violent way by their parents. The researchers asked the young people to rate their childhood exposure to verbal abuse from both parents and other children. Then the researchers performed imaging tests on the brains of the subjects (实验对象).
The images showed that the people who reported suffering verbal abuse from peers (同龄人) in middle school had underdeveloped connections between the left and right side of the brain. The two sides of the brain are connected by connecting fibers (纤维) called the corpus callosum (胼胝体). This was the area that was underdeveloped.
The middle school years are a time when these brain connections are developing. So, unkind, hurtful comments from children or adults during this period have the greatest effect. The researchers tested the mental and emotional condition of all the young people in the study. The tests showed that this same group of people had higher levels of fear, depression, anger and drug abuse than others in the study.
The researchers published their findings online on the American Journal of Psychiatry’s website.
Parents cannot control what other people say to their children, but they can prepare their children.

【推荐1】Don’t drive your kids to school. Let them ride a bike to school.
In England 8.3 million children travel to school every day. It is reported that only a small number of pupils cycle to school (under 2%), although one in three children would actually like to.
Experts say that to stay healthy, children need at least one hour of moderate (适度的) exercise every day. But only six out of ten boys and four out of ten girls get that. One of the reasons is that parents have developed a habit of driving their children to school when they could just walk or ride a bike to school.
Teachers often say that children who walk or ride a bike to school are more ready to listen to their classes, ask and answer questions in class than those driven by car, and the school journey is a good chance for children to learn about road safety and other life skills. Also, for many children, riding a bike is more fun than going to school by car.
Most parents know the benefits (好处). Then what’s stopping them from letting their kids ride a bike? Safety is the number one worry for them. But actually riding a bike is not as dangerous as parents think it is.
1. This passage is mainly written for _______.| A．teachers whose students have asked their parents to drive them to school |

【推荐2】Mandy and Joe have been married for five years and they both love travelling to new countries. But while this hobby brings them together, it is also a source of contention. “I do all the planning and book.” says Mandy. Don’t get me wrong. I enjoy it, but if Joe paid a bit more attention, he wouldn’t have turned up for a flight to Grenada packed for a winter city break. ‘Jumpers and boots?!’I cried.’ You’re supposed to have packed shorts and T-s—it’s 30℃ in the Caribbean!!Then I realized he thought we were going to Granada, in Spain.”
How Joe and Mandy each approach their travel plans is just one example of the many ways in which men and women differ. Yet, is what goes on inside our minds and bodies really so different? Furthermore, are we born that way?
On this issue, scientists are divided. The majority of scientists believed that patterns of behavior thought to be: male or female are learnt firstly from our parents, then from our peers(同伴)and, ultimately, from the societies in which we live. As Simone de Beauvoir famously said, “One is not born, but rather becomes, a woman.”
On the other side of the fence sat those who believed that male and female brains are actually wired (与生俱来的) differently. In one study in which 34 monkeys were required to interact with different types of toys, the males showed s strong preference for toys with wheels rather than soft toys, whereas the females were noticeably drawn to soft toys. These preferences were clearly not the result of parental influence.
Whatever the truth behind the differences between men and women, we can safely conclude that although the social impact on how we think and behave is undoubted, there exists a biological contribution. The question that now needs answering is to what degree biology affects the choices we make and the way other people treat us.
1. What does the underlined word “contention” in Paragraph 1 probably mean?| A．Satisfaction. | B．Disagreement | C．Influence. | D．Information |
| A．Whether men and women are different | B．Why minds and bodies are so different. |

【推荐3】Hardware in general, and smartphones in particular, have become a huge environmental and health problem in the Global South’s landfill sites (垃圾填埋场).
Electronic waste (e-waste) currently takes up 5 percent of all global waste, and it is set to increase rapidly as more of us own more than one smartphone, laptop and power bank. They end up in places like Agbogbloshie on the outskirts (郊区) of Ghana’s capital, Accra. It is the biggest e-waste dump in the world, where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process. They risk their health searching for the precious metals that are found in abandoned smartphones.
But Agbogbloshie legally should not exist. The Basel Convention, a 1989 treaty, aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries. The e-waste industry, however, circumvents regulation by exporting e-waste labelled as “secondhand goods” to poor countries like Ghana, knowing full well that it is heading for a landfill site.
A recent report found Agbogbloshie contained some of the most dangerous chemicals. This is not surprising: smart phones contain chemicals like mercury, lead and even arsenic. Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certain chemical which can cause cancer and damage the immune system at a level that’s about 220 times greater than a limit set by the European Food Safety Authority (EFSA). Most worryingly, these poisonous chemicals are free to pollute the broader soil and water system. This should concern us all, since some of Ghana’s top exports are cocoa and nuts.
Some governments have started to take responsibility for their consumers’ waste. For example Germany has started a project that includes a sustainable recycling system at Agbogbloshie, along with a health clinic for workers. However, governments cannot solve the problem alone, as there is an almost limitless consumer demand for hardware, especially when governments’ green policies are focused on issues like climate change.
Only the manufacturers can fix this. A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable, or at least cost-neutral.
1. What can we infer from Paragraph 2?| A．Electronic waste requires more landfill sites. |
| B．Electronic waste is too complex to get fully recycled. |

【推荐1】Imagine you are in your final days of study in Budapest. So, on your last weekend, you plan a train trip from Budapest to Prague. You only have a couple of days to make the trip.
You buy a ticket leaving on a Friday night. But after your last class, your professor offers a dinner to congratulate you with a celebration. You have to agree, but your eye is always on the clock.
Dinner takes longer than you thought it would and finally you thank him and say you have a train to catch. But he insists you stay for a quick dessert and offers to drive you to the station. You figure that if he drives you, you will have just enough time to catch your train. But after the dessert, he remembers, “Oh, I didn’t drive. How silly of me!” leaving you to hurry to the station.
Unfortunately, the train—your train—is pulling away. And there won’t be another one until the next night. You have missed your train. And that brings us to our expression for today: That train has left the station.
If you like expressions about boats, you can also say “That ship has sailed” or that someone has “missed the boat”. They are all used the same way.
Besides missing an opportunity, all of these expressions could be used in another situation: When events have been put into place and there is no stopping them.
For example, let’s say your mother wants to fix you up with the nice child of her boss. She arranges the date without talking to you first. You don’t want to go, but she has already told her boss you would. She can say “Sorry, but the train has already left the station. You must go on that date.”

【推荐2】Many kids, if not most, have their own cellphones. According to a survey, 12 is the magic number. It is the most common age for kids to get their first cellphone.
People who are for kids’ using cellphones, including many parents, notice that cellphones help kids keep in touch with their friends and families. They believe that cellphones are an important tool in a dangerous situation. Kids can reach their parents at all times. And some people say having a cellphone helps teach kids to be responsible. Some cellphones designed for kids can be set to only work when parents approve. What’s the harm in that?
But other people are worried about the health and safety effects of kids using cellphones. They believe that kids with cellphones will spend less time playing outside with friends, and that chatting on the phone while doing homework makes it difficult for kids to concentrate. They say that kids are spending too much time chatting on the phone instead of talking face to face. “Our brains developed to communicate face to face.” says Gary Small, a teacher in California. “A lot of this is lost with chatting on the phone.”
Another worry is cyber bullying (网络欺凌). It is on the rise as more kids use Wechat to communicate. And some experts are also worried about possible health risks. They worry that energy waves produced by cellphones could be harmful to young people. To be safe, parents should not let kids use their phones too long.

【推荐3】Imagine a school where students are taught by the best teachers in every subject, regardless of location. Imagine a school where students could go on safe field trips to the Amazon rainforest or Everest base camp. Well, such schools are already being built: in virtual(虚拟的)reality.
Last year, Optima Academy Online, an all-virtual school, delivered courses that aim to improve the hearts and train the minds of young people. These courses are of different levels, attracting 170 full-time students from all over Florida. In the progress of home-schooling, students use headsets for about three hours a day for formal lessons and then do course work independently with digital check-ins.
Future versions(版本)of VR will doubtless be widely used in education, but the only questions are: for what purpose and at what speed? There are enough reasons to doubt whether VR schools represent the future of education. Sticking a child in their bedroom with a heavy VR headset fastened to their face and no physical social interaction with other kids will fill many of them and their parents with horror.
A recent report concluded that digital education could significantly improve the quality and equality of schooling systems. But if managed poorly, it could have the opposite effect, turning a digital divide into an educational one. There is growing evidence to suggest that is happening. In Mexico, only 24 percent of 15-year-old students in poor schools have access(使用)to a home computer for schoolwork compared with 87 percent in rich ones.
Used properly, technology can be great for enabling self-motivated students to access learning resources and connect with fellow students and teachers all over the world, says Beeban Kidron, a member of the UK’s Digital Futures Commission. The trouble is that Edtech is too often seen as a shiny new toy that will solve all problems and save money rather than being viewed as a different way to learn, she adds.

【推荐1】More than half the world’s population live in cities, and by 2050 the UN expects that proportion to reach 68%. This means more homes, roads and other infrastructure. In India alone, a city the size of Chicago will have to be developed every year to meet demand for housing. Such a construction increase is a bad sign for dealing with climate change, because making steel and concrete, two of the most common building materials, generates around 8% of the world’s CO2 emissions (排放). If cities are to expand and become greener at the same time, they will have to be made from something else.
Wood is one of the most promising sustainable (可持续的) alternatives to steel and concrete. It is not, however, everyday wood that is attracting the interest of architects.
Rather, it is a material called engineered timber. This is a combination of different layers, each designed to meet the requirements of specific parts such as floors, panels and beams (横梁). Designers can use it to provide levels of strength like steel, in a product that is up to 80% lighter. In addition, engineered timber is usually made into large sections in a factory for future use, which reduces the number of deliveries to a construction site.
According to Michael Ramage of the University of Cambridge, a wooden building produces 75% less CO2 than a steel and concrete one of the same size. However, if building with wood takes off, it does raise concern about there being enough trees to go round. But with sustainably managed forests that should not be a problem, says Dr Ramage. A family-sized apartment requires about 30 cubic metres of timber, and he estimates Europe’s sustainable forests alone grow that amount every seven seconds. Nor is fire a risk, for engineered timber does not burn easily. Besides, fireproofing layers can be added to the timber. All in all, then, it looks as if wood as a building material may get a new lease of life.

Spence’s hair was now grey all over. He had not shrunk much in girth（围长）, though. He stopped watering and looked at the visitor at the gate. Hercule Poirot stood there without moving.
“God bless my soul,” said Spence. “It must be. It can’t be but it is. Yes, it must be Hercule Poirot!”
“Aha,” said Poirot, “you remember me. I’m grateful.”
Spence abandoned the watering can and came down to the gate.
“What brings you down here?”
“What has brought me to many places in my time,” said Poirot, “and what once a good many years ago brought you to see me. Murder, Spence.”
“I’m done with murder since I retired,” said Spence, “except in the case of weeds. Killing weeds is never easy as you think, something’s always wrong. How did you know where to find me?” he asked as he opened the gate and Poirot passed through.
“You sent me a Christmas card. It had your new address on it.”
“Ah yes, so I did. I’m old-fashioned, you know, I like to send round cards at Christmas time to a few old friends. I’m an old man now.”
“We both are.”
“Not much grey in your hair,” said Spence.
“I take care of my hair with a bottle,” said Poirot. “There is no need to appear in public with grey hair unless you wish to do so. By the way, why have you come to live in Woodleigh Common?”
“As a matter of fact, I came here to join forces with a sister of mine. She lost her husband, her children are married and living abroad. So I moved in here. Pensions（退休金）don’t go far nowadays, but we do comfortably living together.”

【推荐3】Reducing, reusing and recycling is a way of life in Sweden. Recycling is required by law and garbage is sorted at home before it goes to a recycling center. Recyclables are sorted into seven categories and recycling stations are within just 300 meters of all residential areas. “Recycling almost everything is a must in Sweden now. It actually feels very uncomfortable when you visit another country and can't find easy ways to recycle,” said Owen Gaffney, an expert at Stockholm Resilience Centre and Future Earth.
But not all of its garbage is recycled. Sweden uses alternatives that include burning garbage to make electricity instead of using fossil fuels to heat 1.2 million homes. About half of household garbage is sent to one of the 33 waste-to-heat plants. Sweden is importing garbage from other countries to keep these plants running. Sweden is also a world leader in turning food waste into eco-friendly biogas. It has made food waste collection compulsory beginning in 2021. There is a food waste biogas plant, which allows biogas to be used to run public buses and to heat apartment buildings.
Sweden now wants to deal with those remaining items that cannot be recycled by using a circular(循环论证的)economy approach. It means that products can be reused and only recycled when absolutely necessary. The Swedish government formed an advisory group to find a new way of making this part of its environmental policy.
This will not work effectively unless people are taught to change their behavior. Now the government is reforming its tax code so that people could get cheaper repairs or buy used things. The large Swedish clothing retailer(零售商)H&M operates a recycling program that gives customers discounts when they bring back old clothing.
Sweden is fighting climate change by doing all the right stuff. Waste recycling and the plans to switch to a circular economy will go a long way in reducing its carbon footprint and will help stop global warming.

【推荐1】When I was four years old，I got stung(螫) by a bee－twice in one week！After that，I had a fear of bees.That's when my parents suggested that I learn about bees instead of being frightened. I read picture books and watched videos about bees，and I learned that bees help make the food we eat because of their pollination(授粉). Take pizza，for example. If we didn't have bees to pollinate tomato plants，we wouldn't have tomatoes for sauce. And we wouldn't have cheese without pollination，either.
The bad news is that bees are struggling to survive. Many are dying. Some scientists think it might be because of chemicals that are used to kill other insects. What would happen if there were no more bees? I wanted to help. I thought, “What if I make lemonade，sell it，and raise money to help bees?” I talked to my grandmother Helen. She gave me her recipe(调制法) for lemonade. It came from a cookbook from 1940.
I added honey to her old recipe. That way，I could sell the lemonade and donate some of the money to groups that are helping to save bees. I could also support local beekeepers by using their honey in my product. And I would be educating others on the importance of bees and helping to save them.
My dad showed me how to work out what supplies I needed to buy. At first，I sold lemonade at a stand at a kids' business event. But I wanted to help bees all year round. We talked to a pizza place near where I live. They said they wanted to sell it. Now more than 30 stores sell it，too. This year we sold about 140,000 bottles. I love helping to save bees. It's the sweetest feeling ever.

【推荐2】An amateur fossil hunter has unearthed a new type of prehistoric “sea dragon” on the beach of the UK's Dorset Coast. The new 2m-long ichthyosaur is named “Etches sea dragon”,after fossil collector Dr. Steve Etches, who found it buried head-first. Ichthyosaurs are called sea dragons for their usually very large teeth and eyes. He thought its teeth were unusual,so he passed it on to experts at the University of Portsmouth to identify(鉴定).There,a Masters student, Megan Jacobs, who has spent several years working on ichthyosaurs, identified it as a new species, which lived 150 million years ago.
The find is the UK's fifth known ichthyosaur from the Late Jurassic periods,and by far the smallest so far.
The fossil was found near Kimmeridge Bay—part of the Jurassic Coast World Heritage Site. When it died, the seafloor would have been very soft mud, allowing the front half of the animal to sink into the mud, before other animals came along and ate the tail end.Being buried in a bed of soft mud meant it was preserved in exceptional condition and even some of its soft tissues were preserved.
Megan said, “Fossils of Late Jurassic ichthyosaurs in the UK are extremely rare. I did some research,comparing it with those known from other Late Jurassic fossils found around the world. It was very exciting that I didn’t find a match. Steve's extraordinary collection contains many new and exciting animals, and it was a real honor to have the chance to describe this ichthyosaur.”
Professor David Martill,who leads the palaeontology(古生物学)research,said, “Steve is an exceptional fossil collector and although he is sometimes referred to as an amateur collector, he has done so much for palaeontology that he has been awarded an MBE, Member of the British Empire, and is truly a professional.”He added, “If it were not for collectors like Steve,scientists would have very few specimens(样本)to work on. ’’

【推荐3】In the long dispute over whether dogs are smarter than cats, a recent study published in the journal Learning & Behavior suggests that dogs are no more exceptional than other animals when it comes to smartness and intelligence.
The news is sure to cause the debate among dog owners and scientists who study dog behaviors. The authors reviewed existing studies and data on animal cognition (认知) and found that while dogs are smart and trainable, they are not “super smart”, despite what most dog owners will tell you. Dog research was quite popular in the 1990s and continues to be so. When it came to other animals, though, scientific studies on intelligence were barely involved in, despite evidence to suggest that horses, chimpanzees ( 黑猩猩 ) and cats had tricks of their own. Almost everything a dog claimed to do, other animals could do too.
Researchers set out to test the supposition (假设，猜想). They compared dog cognition with members of three similar groups: meat-eating animals, social hunters and farm animals. Among the animals they studied were wolves, cats, chimpanzees, dolphins, horses and pigeons. What they found was that “dog cognition does not look exceptional”. Dogs can not use tools, unlike dolphins, New Caledonian crows and chimpanzees, which have been observed using plant stems to hunt for termites (白蚁). Homing pigeons are trained to fly home, sometimes crossing hundreds of miles of unfamiliar area. At the same time, farm animals share similar characters with their dog partners. Horses, like dogs, perform complex tasks. And cats? They have more in common with dogs than one might think. Still it is much easier to show intelligence in dogs because they like to be trained. Dogs are not smarter than they are supposed to be, given what they are.
