Researchers are finding new ways to save snakebite victims.Experts discussed the latest findings during a recent conference.
Scientists in Australia have shown that a chemical called nitric oxide could increase the chances of surviving a poisonous snakebite.The scientists injected rats with a deadly amount of snake venom.Then they rubbed an ointment(软膏)containing nitric oxide on the skin around the injection site.The study found that the rats lived about one-third longer than if nitric oxide had not been used.But the treatment had to be started very quickly.
Dirk van Helden led the research.He says the nitric oxide ointment also showed promise in humans.The study appeared earlier this year in the journal Nature Medicine.Scientists say the findings could help save many lives.A recent study found that poisonous snakes cause as many as ninety-four thousand deaths worldwide each year.But Ulrich Kuch of the Biodiversity and Climate Research Center in Frankfurt,Germany,says that number appears to be low.
Mr Kuch says many deaths could be prohibited if snakebite victims are treated correctly,but they often go to traditional healers or do not seek any help at all.He said,“Sometimes it’s because there is no treatment available—no antivenom(抗蛇毒血清),which is the specific(特殊的)drug to treat snakebites—or health care staff do not know how to treat snakebites,and sometimes its because transportation to get to a health facility is not available or too expensive.
Here is no single antivenom that can be used to treat all snakebites.The antivenom must be specific to the kind of snake that bit the person.In some countries the treatment is costly,while in others there is no such treatment.What is this passage mainly about?( )

Most students hate their endless homework. The students from Class 2, Senior 2 of the High School Affiliated to Peking University certainly did before they published their own collection of English novels at home.
Their small book contains stories about a holy (神圣的) war, the happy life of a self-taught artist and the story of a laid-off worker who devoted his last breath to playing his beloved accordion (手风琴). The book becomes an instant hit on campus. About 3,000 copies have been sold and the class is already working on the second volume.
"We’re up to our ears in homework. Exercises and exams make us out of breath. But to do something creative and full of imagination is such a great achievement," said Yu Xiaoxiao, 16.
"I took the writing as an ordinary homework at the beginning, but after I finished the first part of my story, I could not help but let it flow," said Wang An, who wrote "Accordion".
Inspired by "Lord of the Rings", Jiang Lu wrote his story about magic wars between angels from the light and the dark side. "The main message of the story was to look at the balance of the world. Both dark and light angels fight with love as their weapons. I want to tell people that selfish love might bring hate," Jiang said.
"I was shocked by their work and felt so proud to be the editor of my students’ book," said Nathaniel Timmermann, the oral English teacher at the school. Liu Xiuqin, an English teacher, started the project by asking students to write whatever was in their mind every week. "They have performed beyond expectation," Liu said. "They wrote interesting stories and their English has improved after they started to express their real minds."
"We never imagined that our homework would be so popular and profitable (盈利的). We sell the novels at five yuan, but many teachers pay more to encourage us," said Yuan Mengyao. After Wang An finished the first part of his story, he _________.
| A．couldn’t go on | B．had to put it aside |

“Life is speeding up. Everyone is getting unwell.”
This may sound like something someone would say today. But in fact, an unknown citizen who lived in Rome in AD 52 wrote it.
We all love new inventions. They are exciting, amazing and can even change our lives. But have all these developments really improve the quality of our lives?
Picture this: You’re rushing to finish your homework on the computer. Your mobile phone rings, a QQ message from your friend appears on the screen, the noise from the television is getting louder and louder. Suddenly the computer goes blank and you lose all your work. Now you have to stay up all night to get it done. How calm and happy do you feel?
Inventions have speeded up our lives so much that they often leave us feeling stressed and tired. Why do you think people who live far away from noisy cities, who have no telephones, no cars, not even any electricity often seem to be happier? Perhaps because they lead simpler lives.
One family in the UK went “back in time” to see what life was like without all the inventions we have today. The grandparents, with their daughter, and grandsons Benjamin, 10, and Tomas, 7, spent nine weeks in a 1940s house. They had no washing machine, microwave, computer or mobile phones.
The grandmother, Lyn, said, “It was hard physically, but not mentally.” She believed life was less materialistic. “The more things you have, the more difficult life becomes,” She said. The boys said they fought less to fight over, such as their computer. Benjamin also noticed that his grandmother had changed from being a “trendy（时髦的）, beer-drinking granny, to one who cooked things.”
Here are some simple ways to beat the stress often caused by our inventions!
Don’t be available all the time. Turn off your mobile phone at certain times of the day. Don’t check your e-mail every day.
Don’t reply to somebody as soon as they leave a text message just because you can. It may be fun at first, but it soon gets annoying.The passage is mainly about _______.
| A．problem with technology |
| B．improvements of our life with technology |

Some people are lucky enough to be born with a good sense of direction and even if they have only visited a place once, they will be able to find it again years later.
I am one of those unfortunate people who have poor sense of direction and I may have visited a place time after time but I still get lost on my way there. When I was young I was so shy that I never dared ask complete strangers the way and so I used to wander round in circles and hope that by some chance I would get to the spot I was heading for.
I am no longer too shy to ask people for direction, but I often receive replies that puzzle me. Often people do not like to admit that they didn’t know their hometown and will insist on telling you the way, even if they do not know it; others, who are anxious to prove that they know their hometown very well, will give you a long list of directions which you can not possibly hope to remember, and still others do not seem to be able to tell between their left and their right and you find in the end that you are going in the opposite direction to that in which you should be going.
If anyone ever asks me the way to somewhere, I always tell them I am a stranger to the town in order to avoid giving them wrong direction but even this can have embarrassing results.
Once I was on my way to work when I was stopped by a man who asked me if I would direct him the way to the Sunlight Building. I gave my usual reply, but I had not walked on a few steps when I realized that he had asked for directions to my office building. However, at this point, I decide it was too late to turn back and search for him out of the crowd behind me as I was going to meet with someone at the office and I did not want to keep him waiting.
Imagine my embarrassment when my secretary showed in the very man who had asked for directions of my office and his astonishment when he recognized me as the person he had asked.What is the writer going to do when someone asks him for direction?
| A．He will direct the right way to the person willingly. |
| B．He will reply to it by the means of being a stranger to the town. |
| C．He will give the very person long list of direction. |
| D．He is going to show the man an opposite direction. |
Why did the writer consider himself to be an unlucky dog?
| A．Because of his poor sense of direction. |
| B．Because he always forget the way to home. |
| C．Because he did not have any friend. |
| D．Because he used to be shy and dared not ask others the way. |
How did the visitor feel when he was showed into the very room?
| A．He felt strange. | B．He felt embarrassed. |
| C．He felt very sad. | D．He felt astonished. |
Who showed the right way to the interviewee according to the passage?
| A．Someone we don’t know. | B．The writer did it for himself. |
| C．The secretary did so. | D．A warm-hearted old lady did such a thing. |
Almost two-thirds of children want their parents to spend more time reading to them before bed, and most prefer Mum’s storytelling to Dad’s, researchers said.
They conducted a study that showed younger children aged 3-4 were most hungry for more stories, with over three-quarters saying they wished their parents read to them more often.
More than half of all children aged 3-8 said story time was their favourite pastime with their parents.
"The results of our research confirm the traditional activity of storytelling continues to be a powerful learning and emotional resource in children’s lives," said child psychologist Richard Woolfson.
Storytelling ranked higher than television or video games among pastimes for kids, and 82 percent said reading a story with their parents helped them sleep better, according the survey of 500 children aged 3-8 in Britain.
The best storytellers were mothers who used funny voices to illustrate different characters or made their own special sound effects to keep the story moving, researchers said.
When mum and dad are not at hand, celebrities will do: over 30 percent of children said they would like to hear a bedtime story from Harry Potter star Daniel Radcliffe, with teen idols Zac Efron, Miley Cyrus and Emma Watson.
"It can be very difficult for parents to find the time to read with their children, but these moments can help build strong bonds and play a vital part in their child’s development," said Woolfson.The underlined word “pastime” in the passage mot probably means.
| A．old time | B．entertainment | C．emotion | D．character |
The author develops the passage mainly by.
| A．pointing out similarities and differences | B．following the natural time order |
| C．comparing opinions from different fields | D．providing examples and statistics |
Reading a story with their parents helped most kids aged 3-8.
| A．grow stronger | B．become more emotional |
| C．sleep better | D．become more powerful |
