In 1977, a dead author of detective stories saved the life of a 19-month-old baby in a most unusual way. The author was Agatha Christie, one of the most successful writers of detective stories in the world.
In June 1977, a baby girl became seriously ill in Qatar, near Saudi Arabia. Doctors were unable to find out the cause of her illness with confidence, so she was sent to Hammersmith Hospital in London. She was then only semi-conscious and on the "Dangerously Ill" list. A team of doctors hurried to examine the baby only to discover that they, too, were confused by the very unusual symptoms (症状). While they were discussing the baby's case, a nurse asked to speak to them. "Excuse me," said Nurse Marsha Maitlan, "but I think the baby is suffering from thallium (铊) poisoning."
"What makes you think that?" Dr. Brown asked. "Thallium poisoning is extremely rare."
"A few days ago, I was reading a novel called A Pale Horse by Agatha Christie," Nurse Maitlan explained. "In the book, somebody uses thallium poison, and all the symptoms are described. They're exactly the same as the baby's."
"You're very thoughtful and you may be right," another doctor said. "We'll carry out some tests and find out whether it's thallium or not."
Tests showed that the baby had indeed been poisoned by thallium, a rare metallic substance used in making special glass. Once they knew the cause of the illness, the doctors were able to give the baby the correct treatment. She soon recovered and was sent back to Qatar. Later it was reported that the poison might have come from an insecticide (杀虫剂) used in Qatar. The one who first suggested the correct cause of the baby's illness was _____.
| A．a doctor in Qatar | B．Dr. Brown |
| C．Nurse Maitlan | D．Agatha Christie |
As far as we can tell from the passage, Agatha Christie _____.
| A．had spent a long time studying the baby's case |
| B．visited the baby in the hospital at Hammersmith |
| C．had never met this baby |
| D．gave Nurse Maitlan some advice on the phone |
It seems likely from the passage that the baby's illness had something to do with _____.
| A．a harmful substance used to kill insects |
| B．a dangerous pair of glasses |
| C．the water in Qatar |
| D．a dead writer |
Recently I paid a visit to Harvard University, where there are top class scientists and professors and the best academic system in the world.
I was pretty shocked when I first stepped onto the campus. Well, it’s not ever really a campus. It’s a more like district in a small town.
Harvard's main buildings are from the 18th century. They look very old and simple. You might even say they're a little shabby (破旧的). They don’t fit the modern idea of university at all. The buildings are surrounded by grass and trees, so I felt as if I had walked into a medieval castle. But when I looked across the street, busy shops and in-fashion students made me feel like I was in the 21st century again. It creates a strong contrast (对比) and brings a special atmosphere (氛围) to the school.
Our tour guide Gary took us around and told us: “You see this grass field in the center of the school? Here is where they host their graduation ceremony. They just set up tents and benches and have a very simple ceremony. Unbelievable! Who would think the most talented students just graduate on the lawn?”
I saw some students put a blanket on the grass and lie down to read a book. When I listened to the soft sound of pages turning, along with chirping of the birds, I felt very calm. There was no competitive feeling at all.
Harvard has the world’s first computer in its science center and there are hundreds of high-end computers too. Its religion and the literature departments are also among the best. It is the perfect mix of tradition and new technology. It makes Harvard a very attractive place to study in.
I hope one day I’ll attend my dream school—Harvard.According to the article the author was most impressed by ____.
| A．Harvard’s mix of tradition and new technology |
| B．the classes held on beautiful lawns at Harvard |
| C．Harvard students not taking their graduation ceremony seriously |
| D．the feeling of not living in modern society on the campus |
What can we conclude from the article?
| A．Harvard campus is actually a district of a big city. |
| B．There are no competitions at Harvard University. |
| C．Graduation ceremonies are not complex at Harvard. |
| D．All Harvard buildings date back to the 18th century. |
Which word can be used to describe the Harvard campus?
| A．Modern | B．Competitive | C．Peaceful | D．Splendid |
Chinese scientists have found a new way to use cells found in human urine （尿液）that could aid in the treatment of a range of nerve disorders.That is a new technique for reprogramming cells in human urine into nerve progenitor cells that can grow into multi-functional nerve and brain cells.
The technique is expected to be used in the study and treatment of nerve disorders such as Parkinson's disease, Alzheimer's disease and other nerve disorders.
Pei Duanqing, a professor at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, said his research team has combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram kidney epithelial(肾表皮) cells in urine into NPCs.
These NPCs, normally only found in the human brain, were later proven to be transgene-free and self-renewing, he said.
"These nerve and brain cells can survive for up to one month when transplanted into the brain of a newborn rat," said Pei. "My team is working hard to understand why our experimental condition allowed the urine cells to become NPCs, because we want to improve the technique and make it more efficient".
Scientists have long searched to treat and study neural disorders by obtaining and transplanting neural stem cells. However, the previous method of getting and using cells from either fetal (胎儿)or adult human tissue remains challenging due to ethical concerns and immune system rejections, he said.
Pei hopes the discovery will be used to generate NPCs from patients with nerve disorders such as Parkinson's disease. "These NPCs from patients may help us discover new drugs for these diseases."
"It is a remarkable advance in the stem cell field. The results and methods obtained from this study will be of great value and significance to the field, " said Fred Gage,a professor with the Salk Institute for Biological Studies.What is the passage mainly about?
| A．NPCs are beneficial in treating human diseases. |
| B．Chinese scientists succeeded in making NPCs from human urine. |
| C．Chinese scientists have found cures for all diseases. |
| D．A new technique was used to study the use of human urine |
Pei and his tean try their best to work hard in order to .
| A．make more contributions to medical study |
| B．discover another new technique |
| C．make the technique more perfect |
| D．treat more patients suffering from bad diseases |
What is the challenge of making NPCs in the previous method?
| A．The ethical comcerns and immune system refusal |
| B．The difificulties in getting cells from human. |
| C．The under-developed techniques in medical science. |
| D．The lack of financial support from the government. |
From the last paragraph we can infer .
| A．the new technique will be developed in science |
| B．the results and methods will be applied to treating cancers |
| C．the study will give a major push to the stem cell field |
| D．the mew technique will bring great profis |
After a week-long vacation, U.S. President Barack Obama will focus on proposals to strengthen the still-recovering American economy. The agenda includes the reform of the nation’s health care system.
The Affordable Care Act, or Obamacare as some call it, expands federal health care programs for the needy and encourages Americans of all income groups to purchase private health care insurance.
“If you do not have insurance, beginning on October 1st, private plans will actually compete for your business. You can comparison--shop in an online marketplace, just like you would for cell phone plans or plane tickets. You may be eligible for new tax credits to help you afford the plan that’s right for you. And if you are in the up to half of all Americans who have been sick or have a preexisting condition, this law means that beginning January 1st, insurance companies have to cover you," Obama said.
Health-care spending accounts for one-seventh of U.S. economic activity, and is projected to increase to one-fifth in coming years. The cost has a direct bearing on America’s economic and financial well--being. Drawn up in 2010, the Affordable Care Act aims to control costs and expand access to health care. The effort is a big failure, according to Republican law makers like Tim Griffin and Todd Young.
“Republicans will continue to do everything we can to protect all Americans from the president's top-down, one-size-fits-all, Washington-knows-best approach to health care that is driving up costs and hurting our economy," said Griffin. “The sooner we can delay, oppose and cancel the president's health-care law, the sooner we can get people back to work and focus on expanding opportunity for everyone.”
The president accuses Republicans of putting partisanship(党派偏见) ahead of Americans’ health-care needs. “A lot of Republicans seem to believe that if they can gum up the works and make this law fail, they will somehow be sticking it to me. But they would just be sticking it to you. Your health insurance is not something to play politics with. Our economy is not something to play politics with," he said.
As a matter of fact，the success or failure of Obamacare could shape the president’s legacy long after he leaves office.It is implied in Obama’s words in Paragraph 3 that .
| A．health care insurance will be of great benefit to Americans |
| B．health care insurance will help recover American economy |
| C．insurance companies don’t expect him to carry out the law |
| D．insurance companies will cover Americans in all aspects |
According to Tim Griffin，Obama’s health-care law .
| A．will be strongly opposed to by the Republicans |
| B．will cause fewer economic problems in America |
| C．will be cancelled sooner or later by the government |
| D．will never work without the help of the Republicans. |
What does Obama accuse Republicans of according to the passage?
| A．They don’t know what Americans are in need of. |
| B．They tend to put their own benefit ahead of Americans’. |
| C．They know nothing about health insurance and economy. |
| D．They like to play politics with economy and health insurance |

It’s really true what people say about English politeness: it’s everywhere. When squeezing past someone in a narrow passage, people say “sorry”. When getting off a bus, English passengers say “thank you” rather than the driver. In Germany, people would never dream of doing these things. After all, squeezing past others is sometimes unavoidable, and the bus driver is only doing his job. I used to think the same way, without questioning it, until I started traveling to the British Isles, and here are some more polite ways of interacting with people in UK.
People thank each other everywhere in England, all the time. When people buy something in a shop, customer and shop assistant in most cases thank each other twice or more. In Germany, it would be exceptional to hear more than one thank you in such a conversation. British students thank their lecturers when leaving the room. English employers thank their employees for doing their jobs, as opposite to Germans, who would normally think that paying their workers money is already enough.
Another thing I observed during my stay was that English people rarely criticize others. Even when I was working and mistakes were pointed out to me, my employers emphasized several times but none of their explanations were intended as criticism. It has been my impression that by avoiding criticism, English people are making an effort to make others feel comfortable. This also is showed in other ways. British men still open doors for women, and British men are more likely to treat women to a meal than German men. However, I do need to point out here that this applies to English men a bit more than it would to Scottish men! Yes, the latter are a bit tightfisted.What is the author’s attitude towards English politeness?
| A．He thinks it is unnecessary. | B．He thinks little of it. |
| C．He appreciates it very much. | D．He thinks it goes too far. |
What can be inferred from the passage?
| A．German men never treat a woman to dinner. |
| B．The author think it’s unnecessary to say “thank you” to the bus driver. |
| C．In Germany, employers often say “thank you” to employees for their job. |
| D．Germans think it is unnecessary to thank workers because payment is enough. |
We can learn from the last paragraph that Scottish men ______.
| A．like to fight with each other |
| B．treat women in a polite way |
| C．are as generous as English men |
| D．are unwilling to spend money for women |
The author develops the text through the method of ______.
| A．making comparisons | B．telling stories | C．giving reasons | D．giving examples |
