1 . 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 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(水银), lead and even arsenic(砷). 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.

2 . The brain has a powerful ability to remember and connect events separated in time. And now, in that new study in mice published in Neuron, scientists at Columbia’s Zuckerman Institute have cast light on how the brain can form lasting links.

The hippocampus-a small, seahorse-shaped region buried deep in the brain-is an important headquarters for learning and memory. Previous experiments in mice showed that disruption (中断) to the hippocampus leaves the animals with trouble learning to associate two events separated by tens of seconds.

“The traditional view has been that cells in the hippocampus keep up a level of continuous activity to associate such events,” said Dr. Ahmed, co-first author of the study. “Turning these cells off would thus disrupt learning.”

To test this view, the researchers imaged parts of the hippocampus of mice as the animals were exposed to two different stimuli (刺激物): a neutral (神经的) sound followed by a small but unpleasant puff of air. A fifteen-second delay separated the two events. The scientists repeated this experiment across several trials. Over time, the mice learned to associate the sound with the soon-to-follow puff of air. Using advanced microscopy, they recorded the activity of thousands of neurons (神经元) , a type of brain cell, in the animals’ hippocampus over the course of each trial for many days.

“We expected to see continuous neural activity that lasted during the fifteen-second gap, an indication of the hippocampus at work linking the auditory sound and the air puff,” said computational neuroscientist Stefano Fusi, PhD. “But when we began to analyze the data, we saw no such activity.” Instead, the neural activity recorded during the fifteen-second time gap was sparse (稀少的). Only a small number of neurons worked, and they did so seemingly at random.

To understand activity, they had to shift the way they analyzed data and use tools designed to make sense of random processes. Finally, the researchers discovered a complex pattern in the randomness: a style of mental computing that seems to be a remarkably efficient way that neurons store information.

“We were happy to see that the brain doesn’t maintain ongoing activity over all these seconds because that’s not the most efficient way to store information,” said Dr. Ahmed. “The brain seems to have a more efficient way to build this bridge.”

In addition to helping to map the circuitry involved in associative learning, these findings also provide a starting point to more deeply explore disorders, such as panic and post-traumatic stress disorder.

1. What can we learn about the hippocampus?

A．inspire deeper explorations of disorders

B．provide evidence for language learning

C．build a bridge between different parts of the brain

D．help map some aspects of a person’s experiences

3 . Mathew White, an environmental psychologist, is on a mission to give Mother Nature the respect he thinks she deserves when it comes to human health. For decades, scientists and health-care professionals have recognized that exposure to green spaces, such as public parks or forests, is linked with lower risks of all sorts of illnesses common in the world. Experimental work has demonstrated various physiological responses that occur when people spend time in natural environments: blood pressure drops, heart rate decreases, immune function improves, and the nervous system directs the body to rest and digest.

As humans increasingly populate urbanized areas, they are spending less and less time in natural environments. But before doctors can start advising their patients to head to the nearest park, there is an important outstanding question, says White: How much time in nature do you need to generate these apparent benefits? Most of the research that has linked health outcomes with exposure to the natural world didn’t use frequency or duration of park visits, but rather the amount of green space within a certain distance of a person’s home, White says. But “it’s not so much where you live; it’s whether you use it or not.”

So he collected data to estimate what dose（剂量） of nature was needed to show benefits to a person’s health. White’s group found the answer he was after: Spending at least two hours in nature per week was strongly correlated with self-reports of being in good health or having high wellbeing. “I was very surprised, to be honest,” says White, who had been expecting a much longer time. “We had no idea that such a clear threshold of time per week would emerge from the data.”

He was further surprised to learn that it didn’t seem to matter how many trips to a park people took, so long as they got in their two hours per week. It could be a long visit one day, a couple of hour-long trips, three visits of 40 minutes, or four half-hour excursions. He and his colleagues speculate that, if nature’s apparent health benefits are a result of being able to de-stress, then whatever pattern of green space exposure fits one’s schedule is probably the best way to achieve that goal.

Health-care recommendations for people to spend time in nature are probably years away, but the movement has begun. Several organizations around the world are working to promote awareness of nature’s contribution to health. Some researchers have used the term “a dose of nature” to evaluate the amount of exposure needed to gain benefits. “That was kind of the deliberate medicalization of the language around nature and health,” says White.

D．has adopted the term for his research result

4. What’s the best title for the passage?

A．Respect for Nature	B．Nature as Medicine

5 . The expression, "everybody's doing it," is very much at the center of the concept of peer pressure. It is a social influence applied on an individual in order to get that person to act or believe in a(n) ___ way as a larger group. This influence can be negative or positive, and can exist in both large and small groups.

People are social creatures by nature, and so it is hardly ___that some part of their self-respect comes from the approval of others. This instinct explains why the approval of peers, and the fear of ____, is such a powerful force in many people's lives. This instinct drives people to dress one way at home and another way at work, or to answer a simple “fine" when a stranger asks "how are you?" even if it is not necessarily true. There is a(n) _____aspect to this: it helps society to function efficiently, and encourages a general level of self-discipline that ___day-to-day interaction between people.

For certain individuals, seeking social acceptance is so important that it becomes a(n) ___: in order to satisfy the desire, they may go so far as to ___their sense of right and wrong. Teens and young adults may feel forced to use drugs, or join gangs that ____criminal behavior. Mature adults may sometimes feel ___ to cover up illegal activity at the company where they work, or end up in debt because they are unable to hold back the desire to buy a house or car that they can't afford in an effort to ___ the peers.

However, peer pressure is not always negative. A student whose friends are good at ___may be urged to work harder and get good grades. Players on a sports team may feel driven to play harder in order to help the team win. This type of ___can also get a friend off drugs, or to help an adult take up a good habit or drop a bad one.

Although peer pressure is sometimes quite obvious, it can also be so ___that a person may not even notice that it is affecting his or her behavior. For this reason, when making important decisions, simply going with a(n) ___is risky. Instead, people should seriously consider why they feel drawn to taking a particular action, and whether the real ____ is simply that everyone else is doing the same thing.

6 . What makes a human being? Is it our thoughts? Our emotions? Our behavior?

All of these things make us who we are, but at the center of the matter is the genome(基因组) the genes inside our bodies that may determine everything from our hair color to our intelligence. But if we could change our genome, what would it mean to us?

In an online video posted on Nov. 26, He Jiankui, a biological researcher from Southern University of Science and Technology in China, said that he had helped to make the world’s first genetically edited babies.

These are twin girls, born in November, with genes edited in an attempt to help them resist possible future infection with the AIDS virus.

He said that he chose to do this because HIV infections are a big problem in China. “I feel such a strong responsibility that it’s not just to make a first, but also to set an example,” He told the Associated Press(AP).

The announcement has caused an international storm.

Some believe that success will benefit the families of HIV patients. Given that HIV is “a major and growing public health threat,” attempted gene editing for HIV is “justifiable(无可非议的),” Harvard Medical School genetics professor George Church told AP.

However, others think that since gene editing technology is still premature, it is unsafe to attempt it.

“Gene editing itself is experimental and is still associated with unexpected mutations(突变), capable of causing genetic problems early and later in life, including the development of cancer.” Julian Savulescu, a specialist in ethics(伦理学) at the University of Oxford, told BBC News.

Others fear that this could open the door to using gene editing technology to make designer babies. It might give the parents the options to choose everything from their baby’s eye color to intelligence.

“You could find wealthy parents buying the latest ‘upgrades’(升级) for their children, leading to even greater inequality than we already live with,” Marcy Darnovsky, director of the San Francisco Center for Genetics, told BBC News.

However, Merlin Crossley, a biologist at the University of New South Wales, Australia, believes that’s a long way off . According to him, many genes produce qualities like height and intelligence—not to mention environmental influences.

And he believes the technology will be better controlled in the future.

“It’s hard to get genies(妖怪) back into bottles... but I’m optimistic that this technology, which I think of as ‘genetic surgery’, could be regulated quite effectively in the future,” Crossley told BBC News.

1. According to the passage, which of the four statements is correct?

A．The twin girls with genes edited will not be infected with AIDS.

B．He Jiankui found a way to cure people of AIDS.

C．The genetically edited babies have aroused a heated debate.

D．It makes no sense to edit genes.

2. Who shares the same idea with Julian Savulescu?

A．He Jiankui.	B．George Church.
C．Merlin Crossley.	D．Marcy Darnovsky.

3. What can we infer from the underlined sentence “that’s a long way off”?

A．People will finally accept gene editing, but it takes time.

B．In the future gene editing will surely benefit people.

C．It will take a long time before gene editing succeeds.

D．There is much research to do on gene editing.

4. Which is the most suitable title for the passage？

A．Gene Editing: A Trend for the Future

B．Is Gene Editing the Way we should Go？

C．Can Gene Editing Free People of Future Diseases？

D．Gene Editing: Genies out of Bottles

7 . Though people have discussed the relationship between science and nature for many years, there is no consensual(统一的) explanation. While some view science as a powerful tool in ______ nature’s source of power, others view it as a danger. One example is Barry Commoner’s article, Unraveling(解开) the DNA Myth, which explains the recent developments in DNA technology and expresses ______. Another example is Nathaniel Hawthorne’s short story, The Birthmark. It is a tale about a famous scientist, Aylmer, who seems to be unraveling nature’s deepest secrets one by one. Despite all of his ______ and vast understanding of science, Aylmer is unable to direct that knowledge into ______ free from nature’s grasp. He was unable to rid his wife of her birthmark and, in the end, killed her.

Despite the different presentations of the concepts, though time separated the two men, both pieces express a similar view on the relationship between science and nature. Both pieces suggest that nature is ______ and holds wonders, secrets, and powers that many scientists constantly dream about discovering. Although there is a gap of one hundred and sixty years, Commoner still shares and gives evidence to Hawthorne’s beliefs that there is a unique ______ in nature that cannot be discovered or understood through science and that the ______ to uncover nature’s secrets are ______ and can lead to disaster. According to Commoner, nature’s universal power continues to prevent and control their discoveries. Commoner criticizes and ______ doubt on the true power of science.

As Commoner’s article suggests, nature only allows science to have limited power and success. Both men believe that complete trust in science is ______, however wonderful and groundbreaking some scientific discoveries are. Commoner believes that people only seem to focus on the few achievements, while avoiding and ignoring all of the laws. For example, “most clones exhibit developmental failure before or soon after birth”. By stressing all of the ______ and shortcomings of science, he conveys the notion that nature’s secrets are well kept and far from being understood and ______ by man. The government and private companies have invested billions of dollars in mapping the human genome, but we still have no ______ for it. Such a discovery is useless, however interesting it might be.

Commoner’s article clearly represents science as weak and useless, but more importantly, dangerous. It gives evidence to support the suggested dangers ______ with science’s attempts to discover nature’s power. If the result is not ______ dangerous, it can still have harmful side effects.

8 . We love letters. Just as John Donne, a poet, _________ it, “Letters, to me and my friends mean _________ greetings; they get souls together. Thanks to letters, friends who are _________ speak.” He wrote these words nearly 400 years ago. Today, in the age of instant text message, social media, and email, they _________ ring truer than ever, because writing or receiving a letter has become such a _________ event.

A UK-wide survey undertaken by Sunday Times suggests that one in four of us has not _________ a letter for at least 10 years. That’s ten years without the bitter-sweet _________ of pacing the floor waiting for the _________; ten years without recognizing the handwriting on the envelope and eagerly _________ the letter to read its content.

We ____________ not get them any more, but we still love handwritten letters. In the same survey, one third of ____________ people interviewed say that they ____________ the content of sentimental (充满情感的) letters. Shouldn’t we make ____________ to give our friends and families what they will treasure forever? Ann Bickley went online in 2013 and offered to handwrite a letter to anyone who ____________ her. Her website received 50,000 ____________ in its first three months. Five years later, she is still the main ____________ behind one-million-lovely-letter.com and has personally written 4,000 letters offering hope and ____________ to strangers.

The thought behind a letter ____________ as much as its contents. “I never tell anyone that ____________ is going to be OK,” Ann Bickley says, “I am letting someone know that there is someone in the world who ____________ them.”

One damp afternoon in 2014, a baby red squirrel _______ from his apartment building and landed in the middle of his garden, _______ and bleeding. Although concerned, Andersen _______ the squirrel alone and went inside, _______ that the mother would come and _______ him. But when that didn’t happen, he _______ what he had to do.

_______ picking up the four-week-old baby from the _______ grass, he took him inside, where he was _______ comforted by Andersen’s cat, Coco, who washed him with her ________ and warmed him up. Later, after a veterinarian(兽医) had dressed the squirrel’s wounds, Andersen made his ________ housemate some tiny sweaters and socks to prevent him from ________ his wounds.

10 . Several years ago I started riding a bike. At first, I thought it was only a ______ ride. But as I built up strength, my friends encouraged me to try some longer ______. The first one to come along was a 150-mile journey, an event held every year that ______ money to fight cancer.

When I signed my name, the ______ seemed great — to support a worthy cause while going for the ______ — and I trained with great excitement. But as the time for the ride approached, my ______ gained ground over my endurance(耐力). I didn't really want to ______ all those miles for two days straight.

The ride began on a Sunday morning in the Georgia countryside, ______ for the first few hours I felt wonderful. This was just the ______ I had imagined, and my spirits were ______. But by the end of the day, I felt tired. I was sure I'd have to ______.

As I topped the hill, the nice sunset ______ me going for a few minutes more. Then in the distance, I ______ a lone rider riding very slowly. I ______ that the person looked different in some way, but I couldn't tell why. I managed to ______.
