Face shape lets Al spot rare disorders
People with genetic syndromes （综合征）sometimes have revealing facial features, but using them to make a quick and cheap diagnosis can be _______given there are hundreds of possible conditions they may have. A new neural (神经系统）network that analyses photographs of faces can help doctors _______ the possibilities.
Yaron Gurovich at biotechnology firm FDNA in Boston and his team built a neural network to look at the overall impression of faces and _______ a list of the 10 genetic syndromes a person is most likely to have.
They _______ the neural network, called Deep Gestalt, on 17,000 images correctly labeled to match more than 200 genetic syndromes. The team then asked Al to _______potential genetic disorders from a further 502 photos of people with such conditions. It included the correct answer among its list of 10 responses 91 per cent of the time.
Gurovich and his team also _______ the neural network's ability to distinguish between the different genetic mutations （父异）that can lead to the same syndrome. They used photographs of people with Noonan syndrome, which can result from mutations in any one of five genes. Deep Gestalt correctly identified the genetic source of the physical appearance 64 per cent of the time. It's clearly not _______, but it's still much better than humans are at trying to do this.
As the system makes its assessments, the facial regions that are most helpful in the determination are _______ and made available for doctors to view. This helps them to understand the relationships between genetic make-up and physical appearance.
The fact that the diagnosis is based on a simple photograph raises questions about_______ . If faces can reveal details about genetics, then employers and insurance providers could, in principle, ________ use such techniques to have a ________ against people who have a high probability of having certain disorders. ________ , Gurovich says the tool will only be ________ for use by clinicians.
This technique could bring significant________ for those who have genetic syndromes. The real value here is that for some of these ultra-rare diseases, the process of diagnosis can be many, many years. This kind of technology can help narrow down the search space and then be confirmed through checking genetic markers. For some diseases, it will cut down the time to diagnosis dramatically. For others, it could perhaps add means of finding other people with the disease and, ________ , help find new treatments or cures.

In the face of tragedy，you must of course let yourself feel: Cry without holding back, shake with fear, yell out in anger, accept and follow your feelings. This is part of the wise approach to tragedy: The Upward Path — the feeling of emotions, the acceptance of them, and the coupling of the emotional mind with wisdom. Along this path, you'll take the experience — no matter how sad or upsetting — as a learning event, just as a11 other points on your journey will prove to be. While tragic, you must recognize this is still a chance for all involved to grow. You should let both sadness and joy, fear and courage, dark and light fill your world, and learn to find your steady, calm center in the midst of the opposing forces. This is the Upward Path. Use the event as a chance to gain balance and discover wisdom — the wisdom of love and of letting go, of non-attachment and non-resistance, and using this experience to eventually help others in need of guidance.
Being able to relate to others who have also experienced tragedy and inspire in them hope — of recovery, and of moving forward — is perhaps the greatest gift you can receive from tragedy. Turn the negative into positive, the pain into connection. After you've taken appropriate time to be sad, to feel your own pain, you should make it your work，your goal, your purpose to connect with others who need help. Show them how you've experienced feelings, achieved
balance，and gained wisdom that you would never have otherwise had the chance to learn.

Scientists have connected the “fat gene” with the “happy gene”. They believed there could be genetic evidence which explains why fat people are often happier than their skinny friends. The breakthrough could be an explanation for why fat characters, such as The Laughing Policeman and Father Christmas are often described as joyful and kind.
FTO is the major genetic contributor to being fat. But it is also connected with an eight percent reduction in the risk of depression. Researchers at McMaster University in Canada had been studying whether there was a connection between being fat and being depressed. They found the opposite was true．
They studied 17,200 DNA from participants in 21 countries. Results showed people with FTO gene — the fat gene — showed less signs of depression. This finding was supported by three additional international studies.
Professor David Meyre said, “We set out from the belief that being depressed and being fat both deal with brain activity. We thought that fat genes may be related to depression. However, we have discovered a molecule (分子) contributing to depression. It is the first evidence that an FTO fat gene is connected with protection against depression.
In a recent interview, actress Lisa Riley said she was more than comfortable with her size. She said she is a “big, really happy” girl who is lucky enough to be confident in her own skin, and added, “Many people want to be thinner. Not me. I love being different and it drives me mad that people don’t believe I’m happy with what I am.”
1.According to the passage, FTO is ________.
A. a molecule connected with happiness B. a kind of DNA from participants
C. a gene that contributes to depression D. a gene which leads to being fat
2.According to what Professor David Meyre said, we can know ________.
A. his former beliefs were right
B. fat genes are connected with depression
C. there was no evidence for the role of an FTO fat gene in the protection against depression before
D. there should be more people involved in the study
3.By mentioning the actress Lisa Riley, the author aims to show that ________.
A. Lisa Riley is unhappy with her size B. it’s not easy to be an actress
C. many people want to be thinner D. fat people are really happier
4.The passage is likely to appear in ________.
A. a health magazine B. a lesson plan
C. an advertisement D. an amusement program

A genetic variant(基因变体) that allows people to feel fully rested with fewer than six hours sleep a night has been found. It is the second such finding in recent months.
Ying-Hui Fu at the University of California, San Francisco, and her colleagues have been seeking out genetic variants responsible for short sleep and genetically engineering these variants into mice to confirm their effect. In August. the team found a variant in a gene called ADRB1, which allows 12 members of a family to sleep 4.5 hours per night without feeling tired.
Now the team has found a variant in a gene called NPSR1 in another family, in which one sleeps averaged 5.5 hours a night and the other just 4.3 hours, feeling fully rested. Another variant in NPSR1 has previously been linked to people requiring 20 minutes less sleep than average, based on studies of tens of thousands of people.
Generally, long-term lack of sleep can contribute to many disorders, including obesity, heart disease, high blood pressure and depression. As far as Fu’s team has been able to tell, however, people who sleep less with one of these gene variants are healthy and don’t appear to suffer any ill effects. However, to be absolutely sure would require long-term studies involving large numbers of people, which is not feasible(可行的).
It might be possible to develop drugs that mimic the effects of these variants. However, as NPSR1 is also involved in processes such as stress, anxiety and fear, there is a risk of serious side effects.
1.What did Fu’s team do to confirm the variants effect?
A.Observed blood pressure change.
B.Tested genetic variants on mice.
C.Sorted the effects of different genes.
D.Studied those sleeping less than average.
2.What can we learn about Fu’s team?
A.They are researching variants controlling sleep.
B.They study NPRS1 in a family of 12 members.
C.They have developed drugs to test normal people.
D.They will discover more variants in a week.
3.What does the word “mimic”in the last paragraph mean?
A.Reproduce. B.Compare. C.Avoid. D.Reduce.
4.Where does the text probably come from?
A.A news report. B.A health magazine.
C.A research paper. D.A biology textbook.

Let’s face it: Teenagers spend hours texting, socializing on Facebook and playing video games.And it’s driving their parents nuts.
Sure, there are real dangers connected with all this screen time—everything from cyberbullying(网络欺凌) to couch-potato obesity.Not to mention driving while texting, and shortened attention spans(持续时间).
Douglas Gentile, who studies the effects of media on children, says texting, Facebook and video games are not naturally bad.Nor are they naturally better or worse than watching TV, although they do lead to different risks, such as cyberbullying.
But research has shown that the more time kids spend in front of screens—whether it’s TV or instant-messaging—the worse their school performances are.“That doesn’t mean it’s true for every kid, but it makes sense, that for every hour a kid is playing video games, it’s an hour that they’re not doing homework or reading or exploring or creating,” he said.If screen time is taking the place of doing their homework, that’s bad.But if their homework is done, well, so what?
The study also found that the more time kids spend with media, the lower their grades and levels of personal satisfaction are.Gentile said the influence of screen time on school work can be reduced by what he calls “protective factors”.Those might include good teachers and a high-performing school, love of reading, coming from a family where education is valued.“If you had all these protective factors, then that one little risk factor, who cares?”
One thing parents should worry about is the way electronic devices encourage multitasking（多任务处理).
“As adults, your response speeds up, you’re quicker to look over your shoulder and notice little noises or lights.However this is not what the kids need when they get to the classroom.Scanning to see when the next message comes may not be good for kids.The more distractions(分心的事物) you have, the worse your performance is.” Getting kids to turn off their phones, iPods in order to let them concentrate（集中) on homework is a fight worth having.
1.What statement may Gentile agree to?
A.Kids get bad marks when using Facebook.
B.TV or texting affects kids equally.
C.Kids prefer video games to books.
D.Watching TV is better than playing video games.
2.By saying “one little risk factor”, Gentile referred to ________
A.love for reading B.valuing education
C.screen time D.good teachers
3. It can be inferred from the last paragraph that________.
A.kids can give quick answer to questions if texting
B.Multitasks aren’t really good for every kid
C.electric devices increase the attention of kids
D.kids perform well if doing many tasks together
4.What might be the most suitable title for the passage?
A.Are kids suffering cyber bullying on Facebook?
B.Are texting and Facebook worse for teens than TV?
C.Are kids willing to turn off their electric devices?
D.Are texting causing kids to lose interest in reading?

Many of us rarely check in with ourselves. We rarely wonder what we really want, what benefits us, what delights us, what hurts us, how we can respect ourselves, what people are actually healthy for us to be around and what the most supportive decision is. Or we may know these things but we don’t act on them.
One reason is that we get caught up in what everyone else is doing and thinking. I have to buy that, too! I need to be on that diet if she’s trying it. They think therapy is a waste of time and money. He suggests that I should lose weight. They completely disagree. Maybe I do, too?
When we get caught up like this, we silence ourselves. Here I don’t mean asking others for feedback(反馈) or advice or helpful insights. I’m referring to times when we ignore ourselves and when we let others’ perspectives set aside our own.
When we get caught up like this, what can help is to refocus. To ask ourselves: OK, but what do I want? What works for me? We can ask ourselves questions to check in with ourselves, our needs, our desires, our intentions, and our hearts. These questions reveal important answers. Asking these questions may lead to a new and deeper understanding or perspective. It puts us back in the driver’s seat.
And as I say many times, asking ourselves all sorts of questions means we are listening to ourselves. We’re admitting that our thoughts and feelings matter. Because they do. And in asking questions, in taking the time to listen to the answers, we are building self-trust. We are caring for ourselves in a powerful way.
1.What do we know about people described in Paragraph 1 and 2?
A.They tend to follow suit. B.They like to learn from others.
C.They are too lazy to think hard. D.They have a strong desire to win.
2.Why do we make ourselves silence?
A.Because we follow our own feelings.
B.Because we feel doubtful about things.
C.Because we don’t think about our own ideas.
D.Because we ask others for feedback or advice.
3.Which of the following questions can help you refocus?
A.Why are they happier than me? B.What do my family need the most?
C.What matters most to me in this world? D.How can I follow the traditional values?
4.How can you be in charge of your life?
A.Having a strong power. B.Ready to start out.
C.Leading the way for others. D.Back in the driver’s seat.

Have you ever noticed that the more you have the more you want? Let’s face it. Thinking our life is good enough doesn’t come naturally to many people. When we have high expectations of everything in life we will run into disappointment. Only when we are aware that needs are different from desires can we live with satisfaction. Here are a few ideas to help you be happier with what you have and who you are.
Focus on what you are thankful for. Most people want things to be better than they are, or when things are going well, we forget to appreciate what we have. Learn to reflect on how much better things are than they could be. Focus on what you are thankful for. Write down 5 things you are grateful for right now.
When we hold onto regrets from decisions we have made, it can really poison our well-being. Many people regret something they can no longer change, which ends up holding them back from moving forward in a more positive manner. What happened in the past is done and gone, so work to stay present and be mindful of the current moment to find more joy and fulfillment.
When we use other people as the measuring stick for our personal success and quality of life we are likely to be less satisfied. Social comparisons can provide useful information when we try to learn from others, but they also hold our perspective in a discontented position. Compare yourself less with others so you can be satisfied more.
When you are focused on your big ambitions and future goals you might elide the daily pleasures that surround you. Learn to slow down and absorb the wonder and beauty around you. Stay present and focus on the task you’re undertaking at the moment. Don’t let the life pass you by because you’re always on the go and distracted by ambition.
Practice looking at life through the lens of contentment and it will become more natural.
1. How can we live with contentment?
A. To change our lifestyle.
B. To have a motivation in life.
C. To give less attention to what we are grateful for.
D. To realize the difference between needs and desires.
2.What’s the main idea of Paragraph 3?
A. Make wise decisions. B. Know the present situation
C. Let go of regrets. D. Remember the past.
3.The underlined word “elide”(in Paragraph 5) probably means “__”.
A. enjoy B. change C. create D. neglect
4.What should you do to put yourself in a good mood?
A. Make time for simple pleasures.
B. Learn from successful people.
C. Focus on your future goals.
D. Create chance to learn more.
