A few years ago, a doctor gave a wrong prescription to a 9-year-old boy because he had accidentally clicked the next medicine listed in the drop-down menu. Unfortunately, the boy died.

Dr. Gidi Stein heard the story and felt forced to do something. “It was like killing someone with a spelling error. He just clicked on the wrong button…Stein said. “One would have thought there’d be some kind of spell-checker to prevent these terrible things from happening. But apparently this is not the case.”

Several things were immediately obvious to the 54-year-old Stein, who had previously studied computer science. “If you look at this problem from a bird’s eye view, there were so many places down the line where this decision could have been stopped-from the physician to the pharmacy (药房) even to the mother. All of them had all the relevant information to have the judgment that this was just the wrong drug for the wrong patient. For Stein, it represented a systematic failure.

Stein compared this with credit cards. “If you use your credit card in the daily routine over time, a pattern emerges of how we use our cards : the grocery store, the gas station in our local town. If your credit card would appear tomorrow in Zimbabwe, it would be unusual. The credit card company would call you and say, “‘Hey, was that you?’”

But nothing like that existed in the field of prescription drugs. So Stein set up a company called MedAware. He came up with a machine learning outliner detection system. In other words, he trained the computers to realize if a doctor accidentally prescribed the wrong medicine.

The system is already used in hospitals and doctor5 s offices. To date, MedAware has used their technology to help nearly six million patients in the United States and Israel.

1. What caused the boy’s death?
A.The doctor’s carelessness.B.The doctor’s poor medical skill.
C.The failure of the computer.D.The incomplete health care system.
2. How did Dr. Gidi Stein react to the boy’s death?
A.He was annoyed and put the blame on the doctor only.
B.He was regretful and tried to prevent similar accidents happening.
C.He was embarrassed and mistook it as a systematic failure.
D.He was confused and detected the mistakes in prescriptions himself.
3. What does Stein want to tell us by mentioning credit cards?
A.Credit cards are available for doctors’ prescriptions.
B.Instructions in using credit cards are offered to users.
C.The boy might have been saved with the technology like credit cards.
D.MedAware’s technology will benefit the patients in Zimbabwe.
4. It can be concluded from the text that ________.
A.MedAware’s technology helps doctors choose right medicine
B.MedAware’s technology checks the prescriptions doctors make out
C.Medical industry worldwide has enjoyed MedAware’s technology
D.The boy? s mother was not to blame for his death during the accident

文章大意:本文是一篇说明文。文章主要介绍一些研究人员发现大脑并不是身体中保护最严密的部分,它和身体的其它部分产生的疾病是有联系的。

【推荐1】For decades, scientists thought of the brain as the most valuable and consequently most closely guarded part of the body. Locked safely behind the blood-brain barrier, it was broadly free of the harm of viruses and the battles started by the immune system (免疫系统). Then, about 20 years ago, some researchers began to wonder: is the brain really so separated from the body? The answer, according to a growing body of evidence, is no.

The list of brain conditions that have been associated with changes elsewhere in the body is long and growing. Changes in the makeup of the microorganisms in the digestive system have been linked to disorders such as Parkinson’s disease. There is also a theory that infection during pregnancy could lead to brain diseases in babies.

The effect is two-way. There is a lengthening list of symptoms not typically viewed as disorders of the nervous system, but the brain plays a large part in them. For example, the development of a fever is influenced by a population of nerve cells that control body temperature and appetite. Evidence is mounting that cancers use nerves to grow and spread.

The interconnection between the brain and body has promising implications for our ability to both understand and treat illnesses. If some brain disorders start outside the brain, then perhaps treatments for them could also reach in from outside. Treatments that take effect through the digestive system, the heart or other organs, would be much easier and less risky than those that must cross the blood-brain barrier.

It also works in the opposite direction. Study shows mice have healthier hearts after receiving stimulation to a brain area involved in positive emotion and motivation. Activation of the brain reward centre — called the ventral tegmental area (VTA) — seems to cause immune changes that contribute to it. Working out how this happens could help to destroy cancers, enhance responses to vaccines and even re-evaluate physical diseases that, for centuries, have not been considered as being psychologically driven.

1. What do the researchers focus on about the brain?
A.Its protecting system.B.Its exposure to diseases.
C.Its controlling function.D.Its connection to the body.
2. How does the author support his idea in paragraph 2?
A.By explaining a theory.B.By providing examples.
C.By making comparisons.D.By presenting cause and effect.
3. Which best describes treatments that do not cross the blood-brain barrier?
A.Cheaper.B.More specific.
C.Safer.D.More direct.
4. What does the study suggest in the last paragraph?
A.Brain health depends on immune changes.
B.Brain stimulation leads to negative emotions.
C.The brain can help enhance psychological health.
D.The brain may be key to treating physical diseases.

文章大意:这是一篇说明文。文章介绍了对巧克力中theobromine(可可碱)独特的治疗咳嗽的功效的对比研究,证明theobromine(可可碱)是未来有效的治疗咳嗽的良药。

【推荐2】Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers.

Their study found that theobromine, found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present.

The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. “While coughing is not necessarily harmful (有害的) it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem,” said Professor Peter Barnes.

Ten healthy volunteers (志愿者) were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicine are stopping coughs.

The team found that, when the volunteers were given theobromine, the capsaicin needed to produce a cough was around a third higher than in the placebo group. When they were given codeine they needed only slightly higher levels of capsaicin to cause a cough compared with the placebo.

The researchers said that theobromine worked by keeping down a nerve activity (神经活动), which causes coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness.

1. According to Professor Barnes, theobromine ______.
A.cannot be as effective as codeine
B.can be harmful to people’s health
C.cannot be separated from chocolate
D.can be a more effective cure for coughs
2. What was used in the experiment to cause coughing?
A.Theobromine.B.Codeine.
C.Capsaicin.D.Placebo.
3. We learn from the text that volunteers in the experiment _______.
A.were patients with bad coughsB.were divided into the three groups
C.received standard treatmentsD.suffered little side effects
4. Which of the following would be the best title for the text?
A.Codeine: A New MedicineB.Chocolate May Cure Coughs
C.Cough Treatment: A Hard CaseD.Theobromine Can Cause Coughs

【推荐3】阅读下面短文,并根据题目要求用英语回答问题。

Diana Rae of Tenino, Washington, demonstrates Virtua/(虚拟的)Urgent Care with Dr. Ben Green in Seattle, who consults with her via Skype.

Telemedicine is the name for when doctors give advice to patients by telephone or the Internet, or when health care providers in rural areas connect with specialists in big cities.

Telemedicine has existed for a long time, but the rise of smartphone, tablets and webcam-equipped computers is raising telemedicine to new levels. Some health care systems in the United States now offer Virtual Urgent Care, patients see a doctor by video chat without having to leave home.

Diana Rae recently demonstrated how Virtual Urgent Care works. She used an iPad tablet and Skype—-the video chat service.

Doctor Green first has the patient describe her symptoms. Then the doctor performs a physical exam by demonstrating what he wants her to do. Doctor Green decides that the problem is an infection and gives her some penicillin for medicine. He says about 3 out of 4 patients who have health problems can be treated like this—through Virtual Urgent Care, which means a video chat could substitute a visit to the doctor’s office.

Franciscan charges $35 for this kind of virtual house call, that is much less than the cost of going to an emergency room, a doctor’s office or an urgent care clinic. After trying the video conference, Diana Rae says she would be happy to pay the 35 dollars, when she was recently home with a bad cold. "I would have paid twice that for the convenience of getting taken care of without having to sit in a waiting room, wait, and get exposed to everyone else’s germs." Rae said.

But a company official says state rules have not kept progress with development in telemedicine. The workers who provide Virtual Urgent Care must be licensed separately in each state where the company does business. For now, that means Franciscan doctors can treat patients in Washington state and California, for example, but not in neighboring Oregon or Idaho.

1. What is helping telemedicine to rise to new stages?(No more than 8 words)
2. What does the underlined word "substitute" mean?(1 word)
3. Why would Diana Rae be happy to pay Virtual Urgent Care even more?(No more than 10 words)
4. Why can’t Virtual Urgent Care develop fast now?(No more than 10 words)
5. What do you think of Virtual Urgent Care’s future? Why?(No more than 20 words)
