A woman in the US is able to speak for the first time in 11 years after a pioneering voice box transplant.

Brenda Jensen said the operation was a great success which had saved her life. Thirteen days after the surgery she said her first words： “Good morning, I want to go ” home. ”It is the first time a voice box and windpipe have been transplanted at the same time and only the second time a voice box has ever been transplanted.

Ms. Jensen，52，had been unable to speak on her own since her voice box was damaged during surgery (手术) in 1999. Since then，she has been unable to taste or smell food，could breathe only through a hole in her windpipe and could talk only with the help of an electronic voice box.

In October，doctors at the University of California Davis Medical Centre removed the voice box and 6cm of the windpipe from a donor body. In an 18一hour surgery，this was transplanted into Ms. Jensen's throat and the team connected it to her blood supply and nerves(神经).

Professor Martin Birchall from University College London，who was part of the surgery team，said：”We've learned that we can repair nerves to make even very complex organs function again. It'll open the door to better facial transplants and will be extremely important as tissue (组织) engineering develops. ”

A voice box transplant might be life changing，but it is not life saving. Everyone who receives a transplant must take drugs to control the immune system (免疫系统) for the rest of their lives. These drugs can reduce life expectancy，so they are normally set aside for life saving procedures.

One of the reasons Ms. Jensen was a suitable person for this transplant was that she was already taking immune controlling drugs after a kidney-pancreas transplant four years ago. Professor Peter Belafsky，part of the surgical team，said：“Brenda was an exceptional candidate for the transplant because she was highly motivated. Anyone who's met Brenda knows that she is a strong and determined person with a great attitude towards life in spite of the many physical challenges she's faced over her lifetime. ”

1.The voice transplant surgery is of great importance because it proves that _______.

A. facial transplants are now easier to perform

B. new medical technology is always possible to discover

C. nerve repairing is a breakthrough in tissue engineering

D. the drugs taken after the surgery help the patient live longer

2.Ms. Jensen was a suitable person for this transplant because she was ________.

A. strong—willed and prepared　　 B. experienced and brave

C. seriously ill and motivated　　 D. determined and realistic

3.Which of the following is the fight time order of the event?

a. Ms. Jensen received a voice box transplant operation.

b. Ms. Jensen began to take immune controlling drugs.

c. Doctors removed the voice box from a donor body.

d. Ms. Jensen had a kidney—pancreas transplant surgery.

A. acdb　　 B. dbca

C. bdca　　 D. cabd

4.Which is the best title for the passage?

A. First Words from New Voice Box

B. Transplant Saves A Woman’s Life

C. Courageous Woman Defeating Fears

D. Overcoming Obstacles to Speak Again

WASHINGTON　　 The head of the World Bank says for the first time in human history, it is possible to end poverty around the world. Jim Yong Kim told a Washington audience Tuesday, he wants to make ending world poverty by 2030 a top goal for the bank and governments around the world.

World Bank President Jim Yong Kim says that the problems of poverty, hunger and inequality are wide, urgent and a matter of survival of millions.

“We know that despite the great successes of the last decade, there are still about 1.3 billion people living in extreme poverty, 870 million who go hungry every day, and 6.9 million children under five dying every year,” he said.

But Kim told a Washington audience that the previous successful efforts to cut the number of people living in extreme poverty by half give them hope.

“We are at an auspicious moment in history, when the successes of past decades and an increasingly favourable economic outlook combine to give developing countries a chance－for the first time ever－to end extreme poverty within a generation,” he said in a speech at Georgetown University. “Our duty now must be to ensure that these favourable circumstances are matched with deliberate decisions to realize this historic opportunity.”

Kim says success will require increasing the speed of economic growth, particularly in South Africa and South Asia.

But he warned that civil unrest could happen if economic growth does not help people at all income levels, and also include women and youth．

Kim says that the World Bank and other development agencies will have more resources to get this job done right. “Meeting this 2030 goal will take extraordinary effort,” he said.

However, Kim warned that all the progress in fighting poverty could be destroyed by climate disasters unless the nations of the world do more to prevent climate change.

1.In the opinion of Jim Yong Kim, world poverty _____．

A. is difficult but hopeful to end by 2030

B. exists only in Africa and Asia

C. is not quite hard to end by 2030

D. will be sure to disappear by 2030

2.Which of the following gives Jim Yong Kim the hope to end world poverty?

A.Economic growth is increasing in developing countries．

B.Great successes have been achieved in science and technology．

C.A decreasing number of people are living in poverty．

D.All countries have started to fight poverty．

3.The underlined word "auspicious" in Paragraph 5 most probably means "_____"．

A. unforgettable　　　　　　　　　　　　     B. lucky

C. disappearing　　　　　　　　　　　　     D. important

4.What’s the passage mainly about?

A.The key of ending world poverty is preventing climate change.

B.A top goal－ending world poverty will possibly be achieved by 2030.

C.The success of ending poverty－economic growth.

D.The progress in fighting poverty.

“Nomophobia”, NO Mobile Phone phobia(恐惧) is a 21st-century term for the fear of not being able to use your smartphone. Smartphone addiction is on the rise, surveys show, and a new study released adds to a growing body of evidence that smartphone addiction is harming our minds literally.

Smartphone addiction affects many people from all across the globe. Over 1.8 billion people own smartphones and the average owners check their screens 150 times a day. Considering those numbers, it shouldn’t come as a surprise when 44% of people (compared with 20% in 2011) admit feeling anxious when they can’t have access to their phones.

Researchers from Harvard University used brain imaging to study the brains of 19 teenage boys who were diagnosed with smartphone addiction. Compared with 19 teenagers who were not addicted, the brains of the addicted boys had significantly higher levels of GABA, which decelerates neurons (神经元)， than levels of glutamate-glutamine, which energizes brain signals. That results in poorer attention and control, which you don’t want to have, because you want to stay focused. So that means you are easier to get distracted.

“Addicted teenagers in the study also had significantly higher scores in anxiety, depression and levels of impulsiveness (冲动) ,” said Dr. Leslie Perlow, who led the study.

If you seem to have the symptoms of smart device addiction, experts have some suggestions in addition to mindfulness training. First, turn off your phone at certain times of the day, such as in meetings, when having dinner, playing with your kids, and of course, driving. Remove social media apps, like Facebook and Twitter from your phone, and only check-in from your laptop. Try to stop yourself to 15-minute intervals at set times of the day when it won’t affect work or family life. Don’t bring your cellphone and its harmful blue light to bed, and use an old-fashioned alarm to wake you. And last, try to replace your smart device time with healthier activities such as meditating or actually interacting with real people.

1.What is the conclusion of the research?

A.Smartphone addiction leads to distraction.

B.Smartphone addiction easily causes anger.

C.Smartphone addiction is harmful to the mind.

D.Smartphone addiction brings about anxiety and depression.

2.Where can you find the data that best supports smartphone addiction is on the rise?

A.In Paragraph 2. B.In Paragraph 3.

C.In Paragraph 4. D.In Paragraph 5.

3.Which of the following can replace the underlined word “decelerates” in Paragraph 3?

A.Speeds up. B.Slows down.

C.Adds to. D.Cuts down.

4.Which of the suggestions is encouraged according to the text?

A.To use an old-fashion cellphone. B.To participate in more social activities.

C.To stop fifteen-minute intervals. D.To turn off the blue light on bed.

Tu Youyou has become the first Chinese woman to win a Nobel Prize, for her work in helping to create an anti-malaria(疟疾) medicine. The 84-year-old’s route to the honour has been anything but traditional. In China, she is being called the "three nos" winner: no medical degree, no doctorate, and she’s never worked overseas.

In 1967, malaria, a then deadly disease, spread by mosquitoes was decimating Chinese soldiers fighting Americans in the jungles of northern Vietnam. A secret research unit “Mission 523 “was formed to find a cure for the illness. Two years later, Tu Youyou was instructed to become the new head of “Mission 523”.

“Mission523” read ancient books carefully for a long time to find historical methods of fighting malaria. When she started her search for an anti-malarial drug, more than 240,000 compounds(化合物) around　 the　 world　 had　 already been　 tested,　 without any success.　 Finally,　 the　 team found　 a　 brief reference to one substance, sweet wormwood(青蒿), which had been used to treat malaria in China around 400 AD. The team took out one active compound in wormwood, and then tested it. But nothingwas effective until Tu Youyou returned to the original ancient text. After another careful reading, she changed the drug recipe one final time, heating the compound without allowing it to reach boiling point.

After the drug showed promising results in mice and monkeys, Tu Youyou volunteered to be the first human recipient of the new drug. “In any case, Tu Youyou is consistently praised for her drive and passion. One former colleague, Lianda Li, says Ms Tu is “unsociable and quite straightforward”, adding that “if she disagrees with something, she will say it.”

Another colleague, Fuming　 Liao, who has worked with Tu Youyou for　 more　 than 40　 years, describes her as a “tough and stubborn woman”. Stubborn enough to spend decades piecing together ancient texts, she applies them to modern scientific practices. The result has saved millions of lives.

1.According to Para. I, we can learn that　　　　　　　　　 .

A. Tu is the first woman to win a Nobel Prize

B. Tu has a medical degree

C. Tu’s road to success is not traditional

D. Tu discovered a cure for malaria

2.The underlined word “decimating” in Paragraph 2 can be replaced by　　　　　　　　　 .

A. encouraging　　 B. killing　　 C. annoying　　 D. benefiting

3.Which of the following statements is true?

A. Tu first invented the idea of using sweet wormwood as a cure.

B. Tu was inspired by medical textbooks published in northern Vietnam.

C. The compound needs to be heated to the boiling point to be effective.

D. Over 240,000 compounds were proved ineffective before Tu’s search.

4.Tu Youyou can be best described as a 　　　　　　　　　 person.

A. devoted and stubborn　　 B. straightforward and mean

C. considerate and tough　　 D. sociable and generous
