1 . In spring, chickens start laying again, bringing a welcome source of protein at winter’s end. So it’s no surprise that cultures around the world celebrate spring by honoring the egg.
Some traditions are simple, like the red eggs that get baked into Greek Easter breads. Others elevate the egg into a fancy art, like the heavily jewel-covered “eggs” that were favored by the Russians starting in the 19th century.
One ancient form of egg art comes to us from Ukraine. For centuries, Ukrainians have been drawing complicated patterns on eggs. Contemporary artists have followed this tradition to create eggs that speak to the anxieties of our age: Life is precious, and delicate. Eggs are, too.
“There’s something about their delicate nature that appeals to me,” says New Yorker cartoonist Roz Chast. Several years ago, she became interested in eggs and learned the traditional Ukrainian technique to draw her very modern characters. “I’ve broken eggs at every stage of the process — from the very beginning to the very, very end.”
But there’s an appeal in that vulnerability(易损性). “There’s part of this sickening horror of knowing you’re walking on the edge with this, that I kind of like, knowing that it could all fall apart at any second.” Chast’s designs, such as a worried man alone in a tiny rowboat, reflect that delicateness.
Traditional Ukrainian decorated eggs also spoke to those fears. The elaborate patterns were believed to offer protection against evil.
“There’s an ancient legend that as long as these eggs are made, evil will not exist in the world.” says Joan Brander, a Canadian egg-painter who has been painting eggs for over 60 years, having learned the art from her Ukrainian relatives.

2 . The way Jason Momoa describes Hawaii’s beloved inactive volcano, Mauna Kea, makes you understand why it’s considered sacred(神圣的).
"It’s kind of the umbilical cord(脐带) to earth," the actor tells CNN. "You know, if you think about the Hawaiian islands, that’s the biggest mountain in the world, right? All the way up. So Mauna Kea is the most sacred. We call it the belly button, too. That’s like our birthplace. That’s how our islands were formed. So how can that not be sacred?"
He would know. Jason, a native of Hawaii, has had a near-constant presence there when he’s not working, fighting with local protestors to stop the construction of the Thirty Meter Telescope, or TMT, which would drill directly into the mountain and invade its precious water supply. So far, protestors have successfully blocked the only road crews seeking to go up the mountain in order to build the billion-dollar observatory.
"It started in 2015. What’s happening over there was just not right," Jason says. "And I went over there to meet with everyone to bring the point to the world." Jason joins the protests when he can. He cared so deeply about the preservation of the land that when he had spare time to lend his support, he was there. "You also have to remember, that’s our water source. So having an 18-story building built on top of the tallest mountain from the sea level on our water level is terrible."
The Game of Thrones star says he feels the movement is working and describing his part in it as a calling to do what he feels right in his soul. "There’s massive progress that’s bringing our people together," he says, adding, "I think there are a lot of problems in Hawaii. There are a lot of things that have happened in our history, a lot of injustice, and so we’re shining a light on it. People like myself or Dwayne Johnson, Bruno Mars are trying to spread the concern all around the world. For my soul I need to be there."

3 . Feeling achy and feverish? Your misery has plenty of company. By the end of December, the tally (计数器) of flu-like illnesses in the state exceeded the peaks in the two previous seasons, when the biggest number of cases occurred in February and March. This time, the flu virus seems to be hitting even harder.
Flu is unique among human diseases. It circulates constantly in cool and dry areas. Because it spreads from person to person and can be picked up easily, nearly everyone is exposed. While it’s unclear whether the annual flu epidemic (流行病) will worsen this year, or just arrived earlier, fears have been increased by the severity of flu in Australia during its most recent season and the fact that the vaccine may protect against the predominant (盛行的) kind of the flu only 30 percent of the time.
Despite the worries, doctors and public health officials say there is no evidence that people are getting sicker than usual. Flu cases in Massachusetts started rising around Thanksgiving and increased steadily, with an especially steep climb in the last week of the year. “This is a bad flu season but not a horrible one,” said Dr. Andrew G. Villanueva, a lung specialist and chief quality officer at the Lahey Hospital & Medieal Centre in Burlington.
The flu season, while clearly in full swing, doesn’t “feel different” from previous years, Villanueva said. “We’re not seeing a lot of people being hospitalized because of flu,” he said. “Most people with the flu recover on their own without medical care.”
1. What’s the function of the first paragraph?| A．A lead-in. | B．A comment. | C．A summary. | D．A background. |

4 . Did you ever have to say “no” to somebody? Such as a classmate who asks to go to lunch with you? New research suggests that, at least socially, a rejection (拒绝) should not include an apology. In other words, saying you are sorry does not make the person being rejected feel any better. In fact, it might make the rejected person feel worse. That is surprising. Many people consider it to be good manners to say they are sorry when they turn down a request.
Gili Freedman is doing some related research at Dartmouth College. For her research, she asked over 1,000 people to respond to different examples of social rejection. In one example, the researchers asked people for their reaction (反应）after a person named Taylor asked to join a co-worker who went out to lunch every Friday. And Taylor was told “no”. But in some cases, the person rejecting Taylor offered an apology. In other cases, the people doing the rejection did not say they were sorry. People were asked how they would feel if they were being turned down, just as Taylor was. Most said they would be more hurt by a rejection with an apology than a rejection without an apology.
Freedman said the reason is that apologies make people feel like they need to say that the rejection was okay— even when they felt like it was not okay. Rejection without an apology lets them express their feelings of disappointment, hurt or anger more easily. Freedman also said that an apology often makes the person doing the rejection feel better—even as it makes the person being rejected feel worse.
Her research deals only with social communication. A business situation might be very different. “If a manager rejects a job interviewee or a boss must tell an employee that he or she is being fired from a job,” Freedman said, “reactions to apologies may be different.”

5 . A robot created by Washington State University (WSU) scientists could help elderly people with dementia (痴呆) and other limitations live independently in their own homes.
The Robot Activity Support System, or RAS, uses sensors installed in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities. It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owner to objects like their medication or a snack in the kitchen.
“RAS combines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected,” said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.
Currently, an estimated 50 percent of adults over the age of 85 need assistance with every day activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial strain on the healthcare system by making it easier for older adults to live alone.
RAS is the first robot researchers have tried to incorporate into their smart home environment. They recently published a study in the journal Cognitive Systems Research that demonstrates how RAS could make life easier for older adults struggling to live independently.
“While we are still in an early stage of development, our initial results with RAS have been promising,” Minor said. “The next step in the research will be to test RAS’ performance with a group of older adults to get a better idea of what prompts, video reminders and other preferences they have regarding the robot.”

6 . In a major medical breakthrough, Tel Aviv University researchers have “printed” the world's first 3D vascularized (有血管的）engineered heart using a patient’s own cells and biological materials. Their findings were published on April IS in a study in Advanced Science.
“This is the first time anyone anywhere has successfully engineered and printed an entire heart,” says Prof. Tal Dvir of Department of Materials Science and Engineering, who led the research for the study. “This heart is made from human cells and patient-specific biological materials. In our process, these materials serve as the bioinks, something made of sugars and proteins that can be used for 3D printing of complex tissue models，” Prof, Dvir says. “People managed to 3D print the structure of a heart in the past, but not with cells or with blood vessels (血管).Our results demonstrate the potential of our approach for engineering personalized tissue and organ replacement in the future.”
According to Prof. Dvir，the use of “ native ” patient-specific materials is important to successfully engineering tissues and organs.
The researchers are now planning on culturing the printed hearts in the lab and “ teaching them to behave” like hearts, Prof. Dvir says. They then plan to transplant the 3D-printed heart in animal models.
“We need to develop the printed heart further，” he concludes. “The cells need to form a pumping ability ； they can currently contract (收缩），but we need them to work together. Our hope is that we will succeed and prove our method’s efficacy (功效)and usefulness. “Maybe, in ten years, there will be organ printers in the finest hospitals around the world，and these procedures will be conducted routinely. ”

7 . Babies made from three people approved in UK
Babies made from two women and one man have been approved by the UK’s fertility regulator. The historic and controversial move is to prevent children from being born with deadly genetic diseases.
Doctors in Newcastle — who developed the advanced form of In Vitro Fertilization or IVF (人工授精) — are expected to be the first to offer the procedure and have already appealed for donor eggs. The first such child could be born, at the earliest, by the end of 2017.
Some families have lost multiple children to incurable mitochondrial (线粒体的) diseases, which can leave people with insufficient energy to keep their heart beating.
The diseases are passed down from only the mother, so a technique using a donor egg as well as the mother’s egg and father’s sperm has been developed.
The resulting child has a tiny amount of their DNA from the donor, but the procedure is legal and reviews say it is ethical (伦理的) and scientifically ready.
“It is a decision of historic importance,” said Sally Cheshire, chairwoman of the Human Fertilisation and Embryology Authority (HFEA). “I’m sure patients will be really pleased by what we’ve decided today.”
But some scientists have questioned the ethics of the technique, saying it could open the door to genetically-modified(转基因) ‘designer’ babies.
The HFEA must approve every clinic and every patient before the procedure can take place. Three-person babies have been allowed only in cases where the risk of a child developing mitochondrial disease is very high.
Prof Mary Herbert, from the Newcastle Fertility Centre, said, “It is enormously pleasing that our many years of research in this area can finally be applied to help families affected by these devastating diseases”.
“Now that we are moving forward towards clinical treatments, we will also need donors to donate eggs for use in treatment to prevent affected women transmitting disease to their children.”
Prof Sir Doug Turnbull, the director of the Welcome Centre for Mitochondrial Research at Newcastle University, said, “We are delighted by today’s decision. We will also provide long-term follow up of any children born.”
NHS England has agreed to fund the treatment costs of the first trial of three-person IVF for those women who meet the HFEA criteria, as long as they agree to long-term follow up of their children after they are born.
1. Why is it historically important to approve babies made from three people?| A．It helps couples who lose the ability to give birth to a baby. |
| B．It marks a foundation stone to change babies’ appearances before birth. |
| C．It stops deadly genetic diseases passing down to newly-born babies. |

| A．They pass down on to babies from their parents. |
| B．They prevent people’s heart from functioning normally. |
| C．Some children infected can be cured with proper treatment. |
| D．Babies can be infected with them through a donor’s egg. |
| A．Only when the baby to be born needs it to survive. |
| B．Only when the patient gets financially prepared. |
| C．Only when the clinic gets scientifically ready. |
| D．Only when the technique is ethnically accepted. |
| A．Supportive | B．Indifferent | C．Worried | D．Objective |
8 . In 2015, a man named Nigel Richards memorized 386, 000 words in the entire French Scrabble Dictionary in just nine weeks. However, he does not speak French. Richards’ impressive feat is a useful example to show how artificial intelligence works — real AI. Both of Richard and AI take in massive amounts of data to achieve goals with unlimited memory and superman accuracy in a certain field.
The potential applications for AI are extremely exciting. Because AI can outperform humans at routine tasks — provided the task is in one field with a lot of data — it is technically capable of replacing hundreds of millions of white and blue collar jobs in the next 15 years or so.
But not every job will be replaced by AI. In fact, four types of jobs are not at risk at all. First, there are creative jobs. AI needs to be given a goal to optimize. It cannot invent, like scientists, novelists and artists can. Second, the complex, strategic jobs — executives, diplomats, economists — go well beyond the AI limitation of single-field and Big Data. Then there are the as-yet-unknown jobs that will be created by AI.
Are you worried that these three types of jobs won’t employ as many people as AI will replace? Not to worry, as the fourth type is much larger: jobs where emotions are needed, such as teachers, nannies and doctors. These jobs require compassion, trust and sympathy — which AI does not have. And even if AI tried to fake it, nobody would want a robot telling them they have cancer, or a robot to babysit their children.
So there will still be jobs in the age of AI. The key then must be retraining the workforce so people can do them. This must be the responsibility not just of the government, which can provide funds, but also of corporations and those who benefit most.

9 . More than loo genes are related with increased risk of developing schizophrenia (精神分裂症), bipolar disorder (躁郁症) and alcoholism (酗酒), confirms a large study published in the recent issue of the British scientific journal Nature.
The world’s largest study into the genetic basis of mental illnesses was led by researchers from British universities, including University College London (UCL), Cardiff University and King's College London (KCL).
Researchers believe that they are now much closer than before to understanding the complex biological causes, which make some people being at high risk of developing mental illnesses. They also believe that these findings could lead to new treatments.
The researchers analyzed the DNA of about 37,000 patients with schizophrenia, bipolar disorder or alcoholism, and compared the smallest genetic changes to those found in about 113,000 healthy people. They then identified about 128 independent genetic variants (变体) at 108 locations on the human chromosomes (染色体) that contribute significantly to developing schizophrenia — 83 of these sites have never before been linked to the illness, according to scientists.
For example, people with the variant of the GRM3 gene, thought to be important in brain signaling, are around 2 to 3 times more likely to develop schizophrenia or alcohol dependence. The variant, which is found in approximately one in every 200 people, is also associated with a three times risk of developing bipolar disorder.
“We could be looking at the next big drug target for treating mental illness,” Professor David Curtis from UCL, co-author of the paper, said. “The work opens up new ways to prevent and treat mental illnesses by revealing the mechanisms involved in their development.”

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 lime 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.
