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

Until just a few years ago，we doctors believed that the brain stopped making new neural(神经系统的)connections (meaning that your memory began to get worse)when the body stopped developing，usually in your early 20s. And we knew that，like any other body part，neurons weaken as we age. Loss of brain function due to neural breakdown was assumed to be a normal，unavoidable part of aging.

It turns out that we were wrong. In the past few years，it has been discovered that you can，in fact，make new neurons starting in your 20s and continuing well into old age. You can literally rewire the brain with new parts as the older parts wear out. How？Simple：Keep learning. Just as your body can pack on and condition new muscle，your brain can rebuild used-up neurons.

How strong is the evidence for this？Strong enough that a $200 million industry devoted to brain boosting software (products like Brain Age，MindFit，and Lumosity that supposedly improve your memory function)has sprung up out of nowhere. All“mental fitness”means are keeping your memory intact(everything from phone numbers to how to throw a football)．So what can you do to stay smart?

Keep blood pressure down. People with high blood pressure are more likely to develop cognitive impairment later in life.

Eat more vitamins. Like E(in nuts and sunflower seeds)，B6 and B12(beef，tuna)，and folic acid(leafy greens，citrus，berries)，which help keep your brain’s chemistry in balance.

Exercise your brain. This is the best way to rebuild and strengthen those precious neurons. Learn to play chess or the guitar. When you’re at a stoplight，try to recall the starting lineup of the 1983 Celtics. See a movie that doesn’t feature Ben Stiller. Or read，like，a book.

Dear Dr.Servaas,

I was diagnosed with histoplasrnosis（组织胞浆菌病）30 years ago ．At that time， my doctor told me that it was lung fungus（真菌）that could affect my eyesight.This has happened·Can it affect other organs of the body？

F．Buongiorne

Delta Junction，Arkansas，

Most people have no symptoms resulting from the lung infection，explains histo expert Dr.L.Joseph Wheat，when symptoms do develop，they are usually mild and will disappear without treatment

In some cases，however，histo can spread from the lungs and cause more serious　 problems．

“Histo is more severe in persons with diseases that reduce thcir immunity or who are receiving immunosuppressive（免疫抑制）medications,”says Dr.Wheat，"In such cases，histo can spread from lungs to other parts of the body．Patients with this type of histoplasmosis usually have constant fever，sweats，and weight loss·Excellent tests are available to diagnose this type of histo，and the treatment is highly effective·”

As mentioned by our Arkansas reader，eye problems accompanied by vision loss have been reported long after the first infection．

"Histo is thought by some to be a cause of spots on the back of the eye，called ‘histo spots’，”notes Dr·Wheat．“These injuries cause no problems in some patients， while in others they cause visual loss．There is no proof that histo causes these spots， however，as the organism is not found in the injured parts，and treatment for histo is　 not effective for the eye spots．”

People catch histoplasmosis by breathing extremely small spores（孢子）of the　 histoplasma fungus into their lungs·This fungus is commonly found in areas polluted by　 bird or bat droppings such as caves，chicken cages，barns（谷仓），and under bridges．It will spread through the air during construction or whenever plowing，sweeping，or digging disturbs the soil．

1.What’s the problem with F．Buongiorne？

A.He has recently been diagnosed with his to．

B．He is having difficulty in breathing．

C．He is worried about his health．

D．He has become totally blind．

2.Which of the following is Dr．Wheat’s opinion about“histo"？

A.The disease is equally harmful to all people．

B．The disease will make people put on weight．

C．The disease won’t cause serious problems and no medicine is effective for it·

D．The disease doesn’t，t necessarily have a serious effect on every patient with it·

3.How is“histo" related to“histo spots"？

A."Histo spots" may not be caused by“histo"．

B．Patients with“histo" will have“histo spots"．

C．"Histo spots" will cause visual loss to all patients．

D．“Histo spots" can be cured by the same medicine as cures“histd

4.We can infer from the passage that＿　　　 ．

A.“histo" spreads through water

B．"histo" originates from animals

C．you may have the disease by eating affected chicken

D．workers in a close office are most likely to have“histo"

A few years ago my sister moved from her home in Alabama to Buffalo, New York. Since moving to Buffalo she’s become a big hockey fan and has encouraged me to start watching it. Unfortunately it’s very difficult to find hockey on television here in Alabama. Since hockey games don’t air very much on television I’ve had to look for different ways to watch hockey games.

I often see websites that claim if you go to their website you can watch television on your computer. I try out many of these websites hoping that one of the television stations is a northern station that airs hockey games. Unfortunately, most of them don’t work. Either the site doesn’t really give you what they advertise or their video player doesn’t work properly. But finally I’ve found one website that actually works.

Free Tube is a site that you can go to and watch Television online for free. You don’t have to download any kind of special software or pay money or even sign up for anything. All you have to do is go to Free Tube, choose your channel and start watching.

The different channels to choose from are separated into different categories like news, business, entertainment, music and sports. You’re not going to find channels like NBC or ABC so you can watch the latest episode of Heroes or Grey’s Anatomy but it does include some popular channels like Cartoon Network and ESPN.

There is also a movie section. Each movie channel airs different sorts of films like adventure, classics, comedy or horror and that channel will always air that kind of movies. The movie section also includes my favorite station called Maxx Trailers (预告片). Maxx Trailers airs nothing but movies trailers 24 hours a day. Some of the trailers are for movies coming out and some are for movies that have already been released but already released movies don’t go back farther than a couple of months.

So far I haven’t had any problems with Free Tube’s video player either. Whenever I choose a channel, the video almost always works and usually loads every quickly. The only problem I have with Free Tube is that there is currently a glitch if you’re using Firefox. Once you choose a channel you can’t select another channel to change to, your web browser will freeze up. So if you’re using Firefox, the only way to switch channels is to leave the site and re-enter the site, when choosing what channel you want to go to. However, Free Tube is aware of this glitch and is working with Mozilla to get it fixed right away.

If you’re missing some show everyone is talking about like Grey’s Anatomy or Heroes, this isn’t really a solution for that. But Free Tube is a good way to find channels that you weren’t aware of; there are several good stations to be found.

1.The author mainly ________ in this passage.

A. tells us his experience in using the Web

B. introduces Free Tube to the readers

C. shows us the disadvantages of Free Tube

D. shows us how to enjoy films online

2.The author got interested in watching hockey games ________

A. because he is a sports fan

B. due to his sister’s influence

C. since everyone enjoys the games

D. because he has nothing to do all day long

3.From the passage we can learn that ______________

A. the author is also very fond of movies

B. Maxx Trailers airs to-be-released movies

C. ABC is a very famous TV station in America

D. Firefox is the only software used to watch films online

4. The underlined word “glitch” probably means _________

A. cover                 B. change            C. note                  D. fault
