4.Among all the fast growing science and technology,the research of human genes,or biological engineering as people call it,is drawing more and more attention now.Sometimes it is a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with,such as cancer and heart disease.Every year,millions of people are murdered by these two killers.And to date,doctors have not found an effective way to cure them.But if the gene technology is applied,not only these two diseases can be cured completely,bringing happiness and more living days to the patients,but also the great amount of money people spend on curing their diseases can be saved,therefore it benefits the economy as well.In addition,human life span(寿命) can be prolonged.
Gene technology can help people to give birth to healthy and clever children.Some families,with the English imperial family being a good example,have hereditary(遗传的) diseases.This means their children will for sure have the family disease,which is a great trouble for these families.In the past,doctors could do nothing about hereditary diseases.But gene technology can solve this problem perfectly.The scientist just need to find the wrong gene and correct it,and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture human beings in large quantities.In the past few years,scientists have succeeded in cloning a sheep,therefore these people predict that human babies would soon be cloned.But I believe cloned babies will not come out in large quantities,for most couples in the world can have babies in very normal way.Of course,the government must take care to control gene technology.

66.What does"these two killers"in the second paragraph refer to?C
A.Gene technology and another treatment of the two diseases.
B.The two murderers who killed the cloned baby.
C.The two diseases of cancer and heart disease.
D.Hereditary diseases and cancer.
67.What's the main idea of the third paragraph?A
A.How gene technology can be applied in the field of treating hereditary diseases.
B.Gene technology can be used to clone human babies.
C.Gene technology can help people to give birth to a baby.
D.Gene technology can help the English imperial family out.
68.In what way gene technology can help to treat hereditary diseases?B
A.Using gene technology,people with hereditary diseases can have more living days.
B.Using gene technology,the scientist finds the wrong gene and corrects it.
C.Using gene technology,human babies can be cloned.
D.Doctors can cure cancer and heart disease with the help of gene technology.
69.What is the main purpose of writing this passage?A
A.Expressing the writer's idea that gene technology will benefit people.
B.Telling people the disadvantages of gene technology.
C.Telling the readers that gene technology will not benefit people.
D.Explaining that gene technology will also do harm to the humanity.

2.Escape from FoMO
Here's a test you might enjoy:rate these situations on a number scale,ranging from 1for mild discomfort to 7 for unbearable distress.
Situation 1:you're visiting New York City and realize there's no way you'll be able to get to all the exhibits,see all the recommended plays or take in even part of the"musts".How do you feel now?Something like 5?
Situation 2:you,re at dinner with friends,and you've all agreed to make it a strictly phone-free evening.But your smartphone won't stop beeping Twitter and text alerts.Something is obviously up in your social network,but you can't check.Even 7wouldn't match the stress you're feeling now.
Welcome to FoMO (Fear of Missing Out),the latest mental disorder caused by social media connections sharing updates that leaves individuals feeling that they are missing out on something more exciting,important,or interesting going on somewhere else.It is an outcome of technological advancement and booming social information.According to a recent study,56per cent of those who use social networks suffer this.
It is not uncommon that at night when you've sworn again to put the phone aside or turn off the computer,you cast one last glance at the screen on your way to bed in case you miss some titbit (趣闻)supplied by mere acquaintances or even strangers'requesting your"friendship".
We all know the studies showing that end-of-life regrets centre on what we didn't do,rather than on what we did.If so,constantly watching others doing things that we are not is rich ground for a future of looking back in sorrow.Attractive online images-so charming from afar-make FoMO more destructive.Technology has become the major construct through which we define intimacy (亲密).You may look on in wonder as someone taps out an endless text message instead of actually talking to the person they're with.Being connected to everyone,all the time,is a new human experience; we,re just not equipped to cope with it yet.
Researchers say our dependence on technology can be reduced if we manage to separate ourselves,even for short periods of time,from our gadgets.However,the problem can only be settled when we grasp that our brains and our humanity-not our technologies-enable this addiction.We cannot seek solutions without honestly asking ourselves why we are so afraid of missing out.Researchers find FoMO occurs mostly in people with unfulfilled psychological needs in fields such as love,respect and security.FoMO levels are highest in young people,in particular young men.
What,then,can we do about something so damaging to our quality of life?The best way to cope with FoMO is to recognize that,at our fast-paced life,we are sometimes bound to miss out.Instead of trying to maximize our benefits,we seek a merely"good enough"result.If you still doubt that"good enough"is the best cure for FoMO,the words of the American essayist and poet Ralph Waldo Emerson might strike the right chord,"For everything you have missed,you have gained something else,and for everything you gain,you lose something else."

7.An accident in a bicycle race in the United States eight years ago alerted James Chang to the importance of sports medicine.One of his riding companions(25)was injured(injure) severely in the accident.
From then on,Chang,45,a Chinese-American who was born in Anhui province,began to launch business relating to physical safety and medical assistance,particularly in sport.So(26)whenhe took up marathon running two years ago he was shocked to see frequent injuries,many of them avoidable.
"I always heard people talking about people in marathons in China dying suddenly,"he says,adding that one reason why many of these deaths happen is(27)thatthere is a lot of ignorance in China about what marathon running involves.
Many amateur runners in China who are highly competitive get carried away and run at a pace that is far in excess of(28)whatthey can expect their body to take,and even ignore clear signals such as pain,Chang says.
As Chinese have placed more emphasis on leading healthy life-styles in recent years,marathon and other long-distance running(29)have become(become) a highly popular sport across the country quickly.
More than 50 China Athletic Association-sanctioned urban marathons were held in the country last year,and 39 races involving more than 750,000 runners were held the year before.However,long-distance running is a serious business that can exact a heavy physical toll on runners.
"Marathon carries(30)higher(high) risks of injury than other forms of sport,"Hou says,adding that the key to avoiding injury is to strengthen the body through regular exercise and to be aware of one's own physical condition.
Although some chronic injuries are hard(31)to avoid(avoid),even for highly experienced runners,cramp,fainting and shock can easily be prevent(32)ifrunners better understand the sport,he says.
9.The World Health Organization says there has been a sharp increase in the number of over-weight children in developing countries.In African countries,the WHO says the number of over-weight or obese children is twice as high as it was 20 years ago.Around the world,about 43 million children under the age of five were overweight in 2013.
    Overweight and obese children are more likely to become overweight and obese adults.The
condition can generate serious health problems like heart diseases.
     Francesco Branca is the director of the WHO Department of Nutrition for Health and Development.He says urban lifestyle makes people eat processed food more often,which has a high sugar,fat and salt content.He also says people are gaining weight because of their lack of activities.They travel in cars or other vehicles more than on foot.
     The WHO experts say to lower obesity rates is especially complex in countries that also deal with high rates of infectious(感染性的) diseases.
     The WHO has some basic solutions for individuals and countries.The organization says you should lower your intake of fat,sugar,salt and processed food and eat more fruits,'vegetables and increase physical activity.The WHO says these actions are especially important for children.
     And WHO expert Branca says mothers should breastfeed their babies for at least the first six months of life,if possible.More importantly,governments should consider providing vitamins for children and educational campaigns about problems linked to obesity would also help.In his view,government policies should deal with how food is marketed to children and food producers must balance quality and taste with the dangers of sugar,fat and salt."Reducing the number of overweight children will not be easy.The goal is difficult to meet even in wealthy countries."he adds.
51.What is the main idea of Paragraph l?B
A.Children in developing countries generally weigh too much.

54.According to WHO,which of the following is true?C
A.Poor nutrition is often related to children obesity.
B.To lower infectious disease rates is more complex than to lower obesity rates.
C.Eating less sugar and more vegetables helps lower obesity rates.
D.Increasing  physical activity is most effective to lower obesity rates.
55.What can we learn from the last Paragraph?B
A.Babies breastfed aren't likely to become overweight.
B.Governments should play a necessary role in fighting obesity.
C.Food producers should be stopped from marketing,food to children.
D.The number of overweight children decreases easily in wealthy countries.
5.Why do men die earlier than women?The latest research makes it known that the reason could be that men's hearts go into rapid decline when they reach middle age.
The largest study of the effects of ageing on the heart has found that women's longevity may be linked to the fact that their hearts hardly lose their pumping power with age.
"We have found that the power of the male heart falls by 20-25percent between 18and 70years of age."said the head of the study,David Goldspink of Liverpool John Moores University in the UK."Within the heart there are millions of cells that enable it to beat.Between the age of 20and 70.one-third of those cells die and are not replaced in men,"said Goldspink."This is part of the ageing process."
What surprises scientists is that the female heart sees very little loss of these cells.A healthy 70-year-old woman's heart could perform almost as well as a 20-year-old one's.
"This gender(性别)difference might just explain why women live longer than men,"said Goldspink.
They studied more than 250healthy men and women between the ages of 18and 80,focusing on heahhy persons to remove the confusing influence of disease.
The team has yet to find why ageing takes a greater loss on the male heart,said Goldspink.
The good news is that men can improve the health of their heart with regular exercise.Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

68.The underlined word"longevity"in the second paragraph probably refers toB.
A.health      
B.long life      
C.ageing          
D.effect
69.The text mainly talks aboutD.
A.men's heart cells                 
B.women's ageing process
C.the gender difference              
D.hearts and long life
70.According to the text,the UK scientists have known thatC.
A.women have more cells than men when they are born
B.women can replace the cells that enable the heart to beat
C.the female heart loses few of the cells with age
D.women never lose their pumping power with age
71.We can know from the passage thatA.
A.scientists are on the way to finding out why the male heart loses more of the cells
B.the reason why ageing takes a greater loss on the male heart has been found out
C.the team has done something to prevent the male from suffering the greater loss
D.wome over 70could lose more heart cells than those at the age of 20.
