Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.
Any owner will tall you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people - half of them pet owners –while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did
It best .Those tested with their animal friends had smaller change in blood pressure and returned
Most quickly to baseline heart rates .With pets in the room ,people also made fewer math mistakes
Than when doing in front of other companions. It seems people feel more released (放松)around
Pets, says Allen, who thinks it may be because pets don’t judge.
A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwesterm Memorial Hospital spent a
Year studying 36 fat people and were put on a diet-and-exercise programs; a separate group of
56 fat people without pets were put on a diet program. On average，people lost about 11 pounds，
Or 5% of their body weight .Their dogs did even better，losing an average of 12 pounds，more then
15%of their body weight .Dog owners didn’t lose any more weight than those without dogs but ,say

Running like the wind, roaring (咆哮) like thunder, tigers have long been feared and respected as a king of the animal world. But last week a report said that there are no more than 30 wild tigers left in south China.
This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund.
The South China tiger, also known as the Chinese tiger, is native to southern China. In the 1950's, there were over 4000 tigers found in mountain forests in the country. But due to the destruction of their natural habitat and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species.
Sixtysix of the big cats can be found in the cages of a dozen zoos around China. But they are nothing like their wild cousins. They have lost their natural skills such as hunting and killing. If they were set free they could not look after themselves.
“Breeding has damaged the quality of the species”, said Pei Enle, deputy director of the Shanghai Zoo.
To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa. Four of them have already arrived. Progress has been made as two elder tigers have recovered some of their instincts(本能) and can hunt wild animals by themselves at the African base.
“South Africans are very experienced in reintroducing big animals to the wild. The country has very good natural conditions for the tigers to learn in”, said Lu Jun, office director of the National Wildlife Research and Development Center. “We tried in Fujian Province, but it was not successful as there was not a complete ecochain(生物链) and there was a lack of space.”
The tigers should return to China in 2007 when the reservations in Fujian are ready.What is the main reason for the South China tiger becoming one of the world's top ten most endangered species?
| A．Because it has lost its natural instincts. |
| B．Because there is not a complete ecochain. |
| C．Because there is no space for it. |
| D．Because uncontrolled hunting has destroyed its natural living conditions. |
How is the programme of sending several tigers to South Africa getting on?
| A．Its effect still remains to be seen. |
| B．Two tigers can already compete with their wild cousins. |
| C．Some of the tigers are already on the road to recovering their natural skills. |
| D．The tigers should be able to recover their instincts completely by 2007. |
By saying “but they are nothing like their wild cousins”, the writer means that________.
| A．they are no longer feared by other wild animals |
| B．they don't know how to hunt or kill |
| C．a complete change has resulted in the species because of breeding |
| D．to reintroduce them into the wild has become an urgent task |
What is the purpose of sending young tigers to South Africa?
| A．To help the tigers recover their ability to live in the wild. |
| B．To provide them with a better environment. |
| C．To get the tigers to go on a tour. |
| D．To find a complete ecochain for them. |
My name is Clara.I still remember that chilly December day,sitting in science class.I’d finished a worksheet early and picked up a TIME for Kids magazine. A piece of news caught my eye:NASA was holding an essay contest to name its Mars rover(火星探测器).Before I even knew anything else about it,a single word flooded my 11-year-old mind,Curiosity.
I couldn’t want for the bell to ring so I could get started on my essay.That afternoon,I raced home,sat down at the computer,and typed until my fingers ached. “Curiosity is an everlasting flame that burns in everyone’s mind...”
Five months later, my mon received a phone call,and immediately, a wide smile spread across her face.
On August 5,2012,at 10:31 p.m,the rover named Curiosity touched down safely on the surface of Mars,and I was honored to have a front-row seat in NASA.
Curiosity is such an important part of who I am.I have always been fascinated by the stars,the planets,the sky and the universe. I remember as a little girl,my grandmother and I would sit together in the backyard for hours.She’d tell me stories and point out the stars,Grandma lived in China,thousands of miles away from my home in Kansas,but the stars kept us together even when we were apart.They were always there, yet there was so much I didn’t know about them.That’s what I love so much about space.
People often ask me why we go to faraway places like Mares.My answer is simple because we’re curious.We human beings do not just hole up in one place.We are constantly wondering and trying to find out what’s over the hill and beyond the horizon.How did Clara get the new about the essay contest?( no more than 10 words)
Why did Clara have a front-row seat in NASA?( no more than 10 words)
What does Clara remember about the time spent with Grandma?( no more than 15 words)
What does the underlined phrase “hole up”mean?(1 word)

Here is an astonishing and significant fact: Mental work alone can’t make us tire. It sounds absurd. But a years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we would find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.
So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?
Some scientists declare that most of our fatigue comes from our mental and emotional(情绪的) attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”
What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.What surprised the scientists a few years ago?
| A．Fatigue toxins could hardly be found in a laborer’s blood. |
| B．Albert Einstein didn’t feel worn after a day’s work. |
| C．The brain could work for many hours without fatigue. |
| D．A mental worker’s blood was filled with fatigue toxins. |
According to the author, which of the following can make sitting workers tired?
| A．Challenging mental work. | B．Unpleasant emotions. |
| C．Endless tasks. | D．Physical labor. |
What’s the author’s attitude towards the scientists’ idea?
| A．He agrees with them. | B．He doubts them. |
| C．He argues against them. | D．He hesitates to accept them. |
We can infer from the passage that in order to stay energetic, sitting workers need to ___________.
| A．have some good food. | B．enjoy their work |
| C．exercise regularly | D．discover fatigue toxins |
I heard many parents complaining that their teenage children are rebelling(叛逆). I wish it were so. At your age you ought to be growing away from your parents. You should be learning to stand on your own feet. But take a good look at the present rebellion. It seems that teenagers are taking the same way of showing that they disagree with their parents. Instead of striking out boldly on their own, most of them are clutching(紧握)at one another’s hands for reassurance(安慰).
They claim they want to dress as they please. But they all wear the same clothes. Then set off in new directions in music. But somehow they all end up with listening to the same record together. Their reason for thinking or acting in thus-and-such a way is that many people are doing it. They have come out of their cocoon(茧)into a larger cocoon.
It has become harder and harder for a teenager to stand up against the popularity wave and go his or her own way. Industry has firmly carved out a teenage market. These days every teenager can learn from the advertisements what a teenager should have and be.
And many of today’s parents have come to award high marks for the popularity of their children. All this adds to a great barrier(障碍)for the teenager who wants to find his or her own path.
But the barrier is worth climbing over. The path is worth following. You may want to listen to classical music instead of going to a party. You may want to collect rocks when everyone else is collecting records. You may have some thoughts that you don’t care to share with your classmates at once, well, go to it. Find yourself. Popularity will come with the people who respect you for who you are. That is the only kind of popularity that really counts. In this passage, the author wants to tell .
| A．teenagers how to learn to decide things for themselves |
| B．readers how to be popular with people around |
| C．parents how to control and guide their children |
| D．people how to understand and respect each other |
According to the author, many teenagers think they are brave enough to act on their own, but in fact, most of them .
| A．have much difficulty understanding each other |
| B．lack confidence |
| C．dare not cope with problems single-handed |
| D．are much afraid of getting lost |
What does the author think of advertisements?
| A．Convincing. | B．Influential. |
| C．Instructive. | D．Authoritative(权威的). |
During the teenage years, one should learn to .
| A．differ from others in as many ways as possible |
| B．get into the right reason and become popular |
| C．find one’s real self |
| D．rebel against parents and the popularity wave |
China’s new buzzword, tuhao, may be in nextyear’s Oxford English Dictionary. 
“If its influence continues, it is very likely to appear on our updated list of words, ”said Julie Kleeman, project manager with the editing team.
In Chinese, tu means uncouth and hao means rich. It has traditionally been referred to rich people who throw their weight around in China’s rural areas. In recent years, people borrowed the term to describe those who spend money in an irrational(没道理的)manner. The word gained credence in September with the launch of Apple’s new gold-colored iPhone, an item loved by China’s rich people. The color became known as “tuhao gold. ”The word is now often used by the online community to refer topeople who have the cash but lack the class to go with it.
Kleeman also mentioned two other Chinese words—dama and hukou—which may also be taken in the dictionary. Hukou means household registration in Chinese and has been widely used.
Dama, meaning middle-aged women, was first used in the Western media by the Wall Street Journal in May when thousands of Chinese women were buying up record number of gold. They were the driving force in the global gold market between April and June when the gold prices had slumped(下跌).
“We have nearly 120 Chinese-linked words now in Oxford English Dictionary, ”she said. Some of them are: Guanxi, literally meaning“connection”, is the system of social networks and influential relationships which facilitate business and other dealings. Taikonaut is a mix of taikong, meaning outer space, and astronaut.
The new words will be first uploaded on the official website before the dictionaries arrive. The online version is also renewed every three months. “It at least broke our old rules. It used to take 10 years to include a new word but now we keep the pace with the era, ”according to John Simpson. What does “Tuhao” mean now?
| A．The rich who like iPhone made of gold. |
| B．The people who have power in the countryside. |
| C．The people who spend money reasonably. |
| D．The rich who find no class to belong to. |
Why is the word “Dama” popular now?
| A．They bought gold in the global market. |
| B．They are wealthy middle-aged women. |
| C．They brought the gold prices down. |
| D．They worked on the Wall Street. |
Which word has already been in the Oxford English Dictionary?
| A．Tuhao. | B．Taikonaut. | C．Dama. | D．Hukou. |
According to John, the Oxford English Dictionary .
| A．updates its new version every three months |
| B．takes 10 years to include a new word now |
| C．speeds up its acceptance of new words |
| D．has its online version to collect new words |
