There was once a professor of medicine, who was very strict with his students. Whenever he took the chair on the exam committee, the students would be in fear, because he was seldom pleased with the answers they gave. A student would be lucky enough if he or she could receive a good mark from him. At the end of the term, the students of medicine would take their exam again. Now a student entered the exam room and got seated before the committee. This student was a little nervous as he knew it would not be so easy to get through the exam at all.

The professor began to ask. The student was required to describe a certain illness, his description of which turned out to be OK. Then the professor asked about the cure for the illness, and the student, too, answered just as right. “Good,” said the professor, “and how much will you give the patient?” “A full spoon,” answered the student. “Now you go out and wait for what you can get,” said the professor. At the same time the committee discussed carefully the answers the student had given. Suddenly the student noticed there was something wrong with his last answer. “A full spoon is too much,” he thought to himself. Anxiously he entered the room and cried, “Mr. Professor, I’ve made a mistake! A full spoon is too much for the patient. He can take only five drops. ”

“I’m sorry, sir,” said the professor coldly, “but it’s too late. Your patient has died.”

If you could take a large snapshot (照片) of everyone in the United States today, it would contain six minion more females than males. In this country, women outlive men by about seven years. Throughout the modern world, cultures are different, diets are different, ways of life and causes of death are different, but one thing is the same--- women outlive men.

It starts before birth. At conception, male fetuses(胎儿) outnumber female by about 110 to 100; at birth, the rate has already fallen to about 105 boys to every 100 girls. By the age of 30, there are only enough men left to match the number of women. Then women start taking a lead. Beyond the age of 80, there are nearly twice as many women as men.

“If you look at the top ten or twelve causes of death,” said Deborah Wingard, a disease expert at the University of California at San Diego, “every single one kills more men.” She listed out one sad fate after another – heart disease, lung cancer and so on. Each kills men at roughly twice the rate of that it does women.

More than a century ago American men surpassed and outlived the women. But in the 20th century, women began living longer, primarily because pregnancy（怀孕) and giving birth to children had become less dangerous. The gap grew steadily. In 1946, for the first time ever in the United States, females outnumbered males.

Parts of the reasons are self-made. Men smoke more, drink more and take more life-threatening chances than women. Men are murdered (usually by other men) three times as often as women are. They commit suicide at a higher rate and have more than twice as many fatal car accidents as women do. Men are likely to be involved in alcohol-related deaths.

But behavior doesn’t explain away the longevity gap.

Today, some scientists studying the gender gap believe that the data point to one conclusion Mother Nature may be partial(偏袒) to women.

Every living thing is assembled according to instructions on its chromosomes (染色体), and humans have 23 pairs of them. But in males, one of these is a weak non-matching pair, expressed by “xy”. The agreement pair in females is “xx”, and its genetic “backup” power is sometimes listed as a clue to woman’s superior restoring force. If the male’s single “x” chromosome isn’t perfect, it is possible for a serious genetic disorder to appear. Some blood diseases, for instance, are diseases caused by a shortcoming in a single gene on the “x” chromosome. They are far more common in males than females.

1.What may the underlined word “outlive” in Paragraph1 mean?

A. Become stronger than. B. Live longer than.

C. Be wiser than. D. Be born more earlier than.

2.What can we infer from the second paragraph?

A. Female fetuses are more than male.

B. The female are surpassing the male with age increasing.

D. Over 90, men are more than women in the United States.

3.How many exact diseases are mentioned as examples killing twice men than women?

A. Two. B. Three. C. Ten. D. Five.

4.The best title for this passage is _____

A. Why women live longer than men

Recently, the TV show “Where are we going, Dad?” produced by Hunan SatelliteTelevision is a big hit across nation. Many famous stars brought their children to a strange village alone, and they had to spend 72 hours with their children there. The program fully showed us a modern version of the “how to be a good father”. As the young parents today are too busy to take care of their children, this new form of “Lost on the way” played by nanny Daddy and cute kids triggered（触发）a lot of people’s emotional resonance（共鸣）. Both the kids and their parents will find that their hearts are being drawn closer. But this kind of feeling has just proved that there is a big spiritual barrier between the modern parents and children.

The TV shows like “Children are hard to support!”, “Where are we going, Dad?”, “hot mom” and “cute kids” are becoming more and more popular. All of these show the new parents’ confusion in children’s education and the appeal for the balance between career and family.

In the real life, on the one hand the young parents feel helpless because they are too busy to accompany their children under the pressures of work and life; on the other hand they continue to do so. The data collected by HNTV shows that nearly two-thirds of their audience are female, among whom 36% are aged from 25 to 34.We can imagine such a scene that one evening a young mother is watching the show with her young children, while her husband is still at work or trapped in socializing, or maybe is just playing computer games in the bedroom. The story of a child without the company of father is still going on. In fact, it is sometimes the same to mothers. In a modern family, it is often the old who take the responsibility of raising a child. Theparticipation of mother in the children’s education is also very low.

It is just this kind of confusion where the parents have gone in the modern family education, and where the parents will guide their children to go that “Where are we going, Dad?” shows us. If a child wants to grow up healthily and safely into a modern citizen with independent personality and free spirit, it is very important for him or her to follow the parents who serve as their first teacher. Maybe this is the real reason why such kind of TV programs could get hot. The truth is that children will go where their parents go; and society will go where the children go.

The Internet of Things (IoT) aims to get everything and everyone talking. Attaching sensors to “things”, such as cows, cars and refrigerator, and then assigning them unique IP addresses allow them to “talk” to the Internet. Of course, the IoT will involve much more than a handful of sensors. Networking company Cisco estimates that 50 billion Internet-connected devices and objects will

be sending over data by 2020.

Specific Benefits

The IoT will allow people to track things and processes like never before. Airplane manufacturers will be able to continuously track the condition of airplane parts, allowing them to do preventive maintenance and avoid costly downtime. Consumers could install smart meters in their homes to monitor energy usage and observe energy price changes in real time. That would allow people to adjust their habits and use electrical appliances during lower-priced hours.

Some Fears

Some critics fear that the IoT could end up being a fashion that people lose interest in over time. Having Twitter feeds on refrigerator doors may sound cool at first, but the attraction could fade as quickly as the excitement over last year’s smartphone! Other critics are doubtful that companies making Internet-connected appliances will provide long-term software updates. If that happens, a refrigerator or washing machine that should last 10 years or more could last two or three due to software that’s outdated.

A Positive Example

Early this year, owners of the Tesla Model S electric car received a recall notice alerting them to a charger plug needing to be fixed. Amazingly, owners of the Model S sat back while the company performed an “over the air” wireless update. Customers confirmed the update by tapping on the car’s touchscreen console to see that the Model S was running the latest software version. No trip to the dealer was required!

Perhaps Tesla’s remote fix is a sign of things to come. Someday soon, people’s lives might become a lot more efficient and convenient thanks to the IoT.

1.How do researchers get everything and everyone talking?

A. By establishing the IoT and launching a handful of sensors.

B. By connecting sensors with them and appointing them unique IP addresses.

C. By communicating with them all the time through the IoT.

D. By sending people to track them day and night and collect useful data.

2.According to the article, which of the following is NOT TRUE?

A. IoT can help people do preventive maintenance and save money.

B. IoT can help people monitor energy usage and observe price changes timely.

C. IoT can help people adjust their habits and use electrical appliances more smartly.

D. IoT can help people investigate things and update a lot of important data.

3.What else do critics worry about the IoT besides its probably ending up being a fashion?

A. People will lose interest in it as quickly as the thrill over last year’s smartphone.

B. Refrigerators and washing machines will be replaced by other devices in a few years.

C. Whether related companies will provide long-term software updates or not.

D. The software provided by companies will be outdated easily and quickly.

4.According to the passage, when owners of the Tesla Model S electric received a recall notice, they ______.

A. just waited in the car while the maintenance is being done through wireless update

B. were required to go to the nearest 4s store to make some adjustments or repairs

C. could definitely depend on the IoT to send them the charger plug to be fixed

D. had to confirm the update with the help of the equipment provided by the company
