Death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases --- clinical or temporary death and biological death．Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage．The organism can still be revived(复活)．Biological death occurs when changes in the organism lead to the “breaking up” of vital cells and tissues．Death is then unchangeable and final．
Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs．The best method developed so far involves cooling of the organism, combined with narcotic sleep．By slowing down the body’s metabolism(新陈代谢), cooling delays the processes leading to biological death．
To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta． The scientist put Keta to sleep with a narcotic． Then they surrounded her body with ice-bags and began checking her body temperature．When it had dropped to 28 degrees the scientists began draining blood from an artery．The monkey’s blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in．For twenty minutes Keta remained in this state．Her temperature dropped to 22 degrees．At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing．After two minutes Keta’s heart became active once more．After fifteen minutes, spontaneous(自发的)breathing began, and after four hours Keta opened her eyes and lifted her head． After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room．Her behavior differed little from that of a healthy animal．For a person who suffers from the clinical death, _________．
| A．his most important organs are damaged． |
| B．he still has the possibility of getting back to life． |
| C．he can not avoid final death． |
| D．he is still very much alive |
Scientists try to make the time of clinical death longer in order to __________．
| A．slow down the body’s metabolism． |
| B．bring vital cells and tissues back to active life． |
| C．cool the organism． |
| D．delay the coming of biological death． |
How did the scientists put Keta into clinical death?
A． By putting her to sleep, lowering her temperature and draining her blooD．
B． By surrounding her body with ice-bags and draining her blood．
C． By lowing her blood pressure and stopping her heart from beating．
D． By draining her blood, lowering her blood pressure and stopping her breathing． All of the following indicate that the monkey has almost restored to her original physical state except the fact that__________．
| A．her heart beat again． |
| B．she regained her normal breath． |
| C．she rejected a penicillin injection． |
| D．she acted as lively as a healthy monkey． |
Mr Brown was going away for a week. Before he left, he said to his son, "if anyone asks for me, you can tell him that your father has been out for doing something, and will be back in a week, then be sure to ask him to sit down for a cup of tea.""OK, Dad," said his son.

In England, people often talk about the weather because they can experience (经历) several seasons in one day. In the morning the weather is warm just like in spring. An hour later black clouds come and then it rains hard. The weather gets a little cold. In the late afternoon the sky will be sunny, the sun will begin to shine, and it will be summer at this time of a day.
In England, people can also have summer in winter, or have winter in summer. So in winter they can swim sometimes, and in summer sometimes they should take warm clothes.

Technology and the present generation of kids go hand in hand. Taking advantage of this factor, Lim Hojoon, the designer from South Korea, has come up with an educational gadget (小装置) especially for children.
Kidget, as the name suggests, is a combination of two words – kid and gadget. This kid-friendly gadget has various uses. When your child is in a mood to read, it takes the form of a storybook. When the mood is to draw and color this wonder gadget turns into a perfect canvas (画布). Your child can freely give color to all his/her imaginations. Should he or she wish to have some fun, see this device change into a musical instrument. You too would enjoy doing activities with your loved one using this gadget. This touch screen device will definitely prove to be an ideal friend.
As many parents agree, in this age of technological advancements it is much easier to introduce children to new gadgets than adults. While many adults refrain (克制) from trying out something new, kids are more than prepared to take the leap. Keeping this fact in mind, Kidget is the perfect gift for the child of the 21st century. You will be surprised to see how fast your little one gets acquainted with the device. You might even find yourself lagging (落后) behind at times.
Kidget has another hidden advantage. It helps take the load off young shoulders. With three things rolled into one, a child has much less books, stationary items and related goods to carry. It comes with a promise to make life simpler for kids. Not only is it simple to use but also easy to carry along. The stylish protective case comes with a belt attached to it. Children up to 14 years of age, the targeted audience, enjoy the freedom that comes with it.The Kidget probably can’t serve as a ______.
| A．storybook | B．perfect canvas |

Visit any junior high or high school and you will experience the power of influence. Clothing, hairstyles, attitudes and even the language are all gained by some amount of influence, whether it is from commercials, fashion, trends, celebrities or music. Teens and preteen children are influenced by these various factors. However, a child’s friends are the No. 1 influence.
Before you think your children’s friends could never lead one another astray (误入歧途的), think again. A child may experience an event that has caused overwhelming stress or may have problems at home or school, which causes negative behavior. Negative influences of a child’s friends can come without warning.
“Parents who ask their children where they are going, who they are going with and request a meeting with their children’s friends and the friends’ parents have already taken the first step,” says Mara Berkley, family therapist and professor at Bristol University in Rhode Island.
Lynn Rexroat of Chillicothe, Illinois, uses this method to keep tabs on her children. “My oldest son knows that in order for him to go anywhere with a friend, especially one I haven’t met before, I have to speak with that friend’s parent to make sure the arrangements are agreeable with us both,” she says. “I don’t interrogate (质问) them by asking about their private life. I just want to know that the parents of the other child know what the boys are planning to do. I feel that by my wanting to know I am protecting my son.”
When a parent suspects that their child is hanging out with “the wrong crowd”, the last thing on their mind should be discipline. Instead, Berkley says a parent should be more interested in finding out the reasons behind the behaviors and the child’s choice to keep company with these types of friends.We can infer from the second paragraph that .
| A．two children usually go astray together |
| B．a child can be negatively influenced only when he meets problems |
| C．a child can easily go astray under the influence of a friend |
| D．parents know exactly when a child is negatively influenced |
Mara Berkley probably agrees that you when your child is going out with his friends.
| A．should track him secretly | B．should not ask him |
| C．can stop him going out | D．do something to interfere |
How does Lynn Rexroat protect her son according to the text?
| A．She questions his son directly. |
| B．She meets his son’s friends herself. |
| C．She makes arrangements with the parents of his son’s friends. |
| D．She communicates with the parents of his son’s friends. |
The underlined part “keep tabs on” in the fourth paragraph probably means “ ”.
| A．watch over | B．win over | C．bring back | D．take control of |
Smart home applications can share all kinds of helpful information with homeowners. There appears a new housing platform which can detect the stress on electricity — and the stress on the heart.
“There is a growing population of elderly people, and there are statistics to show that more and more of them are going to live alone in the home,” said Johann Siau, a senior lecturer at the University of Hertfordshire in the U.K., who was leading the InterHome project.
The system was originally designed to provide remote access (远程访问) to a house so owners could be more energy-efficient. In a small type of the system, set-in controller devices connect securely to the Internet. The owner can then monitor them with a cell phone or computer. User feedback helps the system adapt to routines, saving on electricity.
While thinking about responding to user behavior and an increasingly elderly population, the researchers decided to add wristband (手腕带) technology that senses important organs of the body such as body temperature and pulse, Siau said. “If someone were to fall, it would detect the fall and it would immediately start the monitor of the pulse to see if the person has gone into shock (休克),” he said.
The wristband communicates with the home system wirelessly. Data from the band can be securely transmitted to the home network and accessed by authorized users. “We’re working on trying to reduce it to a level where it could potentially be a wrist-sized product,” Siau said.
But he warned that the technology presented new challenges. “When you start using that on a larger scale, you have issues of privacy or security,” he said. Siau said the InterHome home system isn’t intended to invade privacy. “We’re thinking about the elderly people who are living alone with no one looking after them,” he said. “Hopefully this will be able to decrease some concerns and possibly save a few lives.”The system was first designed for a house owner to .
| A．keep watch on his house |
| B．keep his house safe |
| C．monitor the elderly people inside |
| D．save electricity |
The wristband technology is used in the system to .
| A．sense important organs of a person |
| B．keep an old man from falling |
| C．get the medical information of a sick person |
| D．record a person’s daily activities |
The researchers are now trying to make the wristband .
| A．more sensitive |
| B．be connected with the Internet |
| C．available for common people |
| D．suitable to wear on the wrist |
What challenges will the new technology bring according to Siau?
| A．The wristband can be large and expensive. |
| B．The wristband will get false information of a person. |
| C．It will not be used in the proper way. |
| D．It will bring inconvenience to the old people. |
