Have you thanked your grandma today? You might want to consider it. A recent study found that kids live longer when a grandmother takes part in their daily lives.
Most animals die soon after their childbearing years are over. Women, however, often live for many years after they stop having kids.
To try to understand why, researchers from Finland looked at birth and death records of two communities from the 18th and 19th centuries, one in Finland and one in Canada. In these communities, 537 Finnish women and 3,290 Canadian women were grandmothers who had lived past the age of 50.
For every decade they lived beyond 50, the researchers found that the women ended up with an average of two extra grandkids. It didn’t matter what the differences in health or living conditions were between the two communities or from family to family.
Grandchildren were also more likely to live into adulthood if their grandmothers were alive when they were born. If their grandmothers were younger than 60 at the time, that was even better. The study also found that women had children 2 to 3 years earlier if their own mothers were still alive at that time than those whose mothers had died.
The researchers suggested that grandmothers have provided important assistance in raising their grandchildren for at least the past 200,000 years. As a result, they helped extend everyone’s lifespan.
So, don’t take your grandma for granted!How many women in the survey in the two communities were grandmothers who had lived past the age of 50?

Liz had been bleeding for a long time! She was my closest professional colleague and good friend at the time when we worked in an IT company. It was her first day back at work after an operation and I thought she should have taken a few more days to recover.
Realizing that we couldn’t stop the bleeding, we headed to the emergency room and spent hours there waiting to be seen. After the treatment, I drove her to my apartment. I had to leave her in my apartment while I dashed off to take a final exam for a very important course I was taking. Upon my return, we decided Liz was in a good enough condition to sustain a trip back from my Northern Virginia apartment to her home in Maryland.
Although it was nearly midnight and we were both exhausted, we still decided to set off. Unfortunately, in a not particularly safe part of town, we heard my car make a strange noise, and then ti was shaking violently as we drove along. Quickly, I stopped the car in the road and found a tire had blown out. Not knowing how to change a tire and feeling scared, I was trying out to figure out what to do next. Liz, weak from losing all that blood all day and weighing only about eighty pounds to begin with, came out and tried to help me. I had to scream at her to get back in the car and relax.
Within seconds, a taxi pulled up behind us. A huge man appeared and began walking toward us. I felt that the blood drained out of my face and I nearly fainted in fear.
“Got a flat tire, girls?” he asked.
“Yes,” I answered in a trembling voice.
In no time at all, the man changed the tire for us and rushed off back to his taxi. He refused any payment and did not even tell me his name.

Hilary Smith belonged to a good family. But by the age of twenty, he had spent all the money the good old family had. He then had some trouble with the bank and was put in prison. He escaped from the prison and ran to Australia without delay.
Hilary did not like Australia and Australia did not like Hilary. What he could do seemed to be one of two things: die or work. Then he remembered that he was not alone in the world. He had an aunt.
She was his father's only sister, but his father used to say she brought no glory to the family. Hilary, of course, tried to discover what she had done. It seemed that she had failed to marry a nobleman. Instead, she had chosen a husband who was connected with "trade". Of course as soon as she became "Mrs. Parks", her brother considered her dead. Later on, Mr. Parks died and left her a lot of money; but that did not bring her back to life in her brother's opinion.
Hilary discovered his aunt's address. Fortunately she remained faithful and honest to him even after she fell ill. So Hilary's star shone again, and soon he moved into her house and lived as comfortably as a sailor who had just reached harbor. He had only about a sixpence in his pocket.
One thing was soon clear: his aunt was seriously ill, and nothing could cure her illness. Hilary was very worried. Fate had found a home for him, and was now going to throw him out of it. There was only one thing that could save him: her will.
"Will?" she said, "yes, I have made one. That was when I was a girl and had not much money. I left all my money to some religious people."
"Didn't you make another will when you were married?" Hilary asked.
His aunt shook her head. "No," she said in a low voice, "There was no need. When I finally had a lot of money I found 1 had no relations."
On the next day he went to the public library and examined a book of law. It told him what he already believed. When a woman is married, an earlier will loses its value. A new will must be made. If no new will is made, the money goes to the nearest relation. Hilary knew that he was his aunt's only relation. His future was safe.
After a few months had passed, Hilary's problems became serious. He badly needed money. He had expensive tastes, and owed a lot of money to shopkeepers. They trusted him because his aunt was rich; but the debt was terrible.
Unfortunately his aunt did not want to discuss money matters at all. In the end they had a quarrel about the small amount of ten pounds. Hilary was not very angry. He began to wonder about a new problem. Was it kind to want his aunt to live any longer? Was it not better for her to die now? While he was considering what to do, his aunt told him that she was going to send for her lawyer. So she was going to make a new will, Hilary thought. She might leave all her money to someone else. Soon he reached a clear decision. He must do a great kindness to the poor old woman.
One night when the old servant who had been nursing his aunt went off, he doubled the amount of some medicine. The total amount was too great and it could just put her to sleep forever.
"Thank you," his aunt took the glass from his hand with a grateful look." I want, more than anything, to sleep, and never to wake up again. Is that what you wish, Hilary? Don't blame me if I have some doubts about what you intended to do. Sick people get these ideas, you know. One thing I ought to explain to you. Mr. Parks never married me. He already had a wife and couldn't marry again. That made your foolish father very angry with me...Well, if I am alive tomorrow I shall make another will in your favor. If I die tonight, you'll get nothing...No, Hilary, don't try to take the glass away. If you do that, I shall know; and I don't want to know. Good night, Hilary."
Then, very carefully, she raised the glass to her mouth and drank.From the story ,we learn that Hilary's aunt was ______.

You never see him, but they're with you every time you fly. They record where you are going,how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book.They're known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.
In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device（装置） was completely redesigned and moved to the rear of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.
Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations,and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated ( 隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.In Paragraph 1，the author wants to say the black box_________.
| A．is an necessary device on an airplane |
| B．comes from a comic book |
| C．can prevent disasters |
| D．can control the function of an airplane |
From the black box on the Yemeni airliner_________could be found.
| A．the scene of the crash and the degree of the damage |
| B．the total number of passengers on board |
| C．data for analyzing the cause of the crash |

Why was the black box redesigned in 1965?
| A．New materials became available by that time. |
| B．The early models often got damaged in the crash. |
| C．Too much space was needed for its device. |
| D．The early models didn't provide the needed data. |
The black boxes were painted orange or yellow to_________.
| A．distinguish them from the colour of the plane. |
| B．warn people to handle them with care |
| C．make them easily identified. |
| D．obey the international standards. |

| D．They were destroyed somewhere near Brazil. |
(RAMALLAH, West Bank) — Israel（以色列） freed 26 Palestinian（巴勒斯坦） prisoners early Wednesday, the second of four groups to be released as part of an agreement that started the current Israeli-Palestinian peace talks, which had broken down since 2008. In all, 104 prisoners are to be released in four rounds over the coming months.
In the West Bank and Gaza（加沙）, the mood was overexcited as hundreds of Palestinians welcomed the prisoners back home, after many had spent more than 20 years behind bars.
Crowds of people rushed toward the 5 prisoners released to Gaza, raising them on their shoulders, waving Palestinian flags and dancing to music. Relatives held signs that read “we will never forget our heroes.” More than 2,000 people welcomed the 21 prisoners released to the West Bank, who were greeted at a ceremony by Palestinian President Mahmoud Abbas in Ramallah.
Hazem Shubair, thrown into prison in 1994 for the death of an Israeli according to the Israeli Prison Service, was over delighted upon his return to Gaza. “I am speechless,” he said. “Thanks to God. God is greater than the aggressors (meaning Israel)”.
Abbas said a final peace agreement with Israel was possible on the release of the prisoners. “There will be no final agreement without the release of all the prisoners,” he told the violent crowd.
Israel’s Supreme Court (最高法院) earlier refused an appeal that intended to cancel the prisoner release. An organization of bereaved (失去亲人的) families behind the appeal has said it fears the prisoners, all in connection to the deaths of Israelis, will return to violence once freed.Why did Israel free 26 Palestinian prisoners early Wednesday?
| A．Because they would take part in the Israeli-Palestinian peace talks. |
| B．Because that was part of an agreement between Israel and Palestinians. |
| C．Because the current Israeli-Palestinian peace talks failed. |
| D．Because the peace talks had broken down since 2008. |
How many Palestinian prisoners had been released by Wednesday?
| A．21 | B．26. | C．Over 26. | D．104. |
Which of the following is true according to the passage?
| A．Wednesday’s release was the whole part of the Israeli-Palestinian peace talks. |
| B．The other 104 Palestinian prisoners will be freed in the coming months. |
| C．All the Palestinian prisoners were greeted by Palestinian President Mahmoud Abbas. |
| D．All the Palestinian prisoners were welcomed warmly. |

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. |
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. |
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. |
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. |
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 |
