Nowadays, there’s a lot of debate about single sex education since it has begun to regain its popularity recently. According to long term studies of children from around the world, students achieve more and learn better in single sex schools.
An Australian study of 270,000 students found that both boys and girls performed much higher on standardized(標(biāo)準(zhǔn)化) tests when they attended separate schools. During an experiment in Virginia in 1995, 100 eighth graders were separated just for math and science courses. Almost immediately, the girls began to achieve more, become more confident and take part more often in class activities.
In 2001, a British study concluded that nearly every girl regardless of (不論) her ability or socio-economic status performed better in single sex classrooms than co-ed ones. The study of 2,954 high schools and 979 primary schools showed that while boys at the lowest levels in study improved the most in single sex schools, single sex education was particularly beneficial (有益的) to girls. Every one of the top 50 private elementary schools and top 20 private high schools in Britain are single sex schools.
Girls became more confident in themselves as students and earned higher scores on their College Board and Advanced Placement examinations. A quarter of the female members of the US Congress and one-third of all female members of Fortune 100 boards graduated from all-women’s colleges.
While the statistics are not as dramatic for boys, however, boys tend to soften their competitive edge and become more cooperative in a single sex setting. They can just be boys and not worry about what the girls might think.
Single sex education has a pleasant way of encouraging children to be fearless, to be curious, to be enthusiastic --- in short, to just be themselves. Children are subjected (屈從于) to pressures from every quarter to become adults before they are ready to do so. They grow up too quickly. Why not let them be children for a few more years? Single sex education with its gentler, more controlled social atmosphere is just the right answer for many children.

Driving home from work one evening in the heavy rain, I found a very wet, injured cat on the side of the road. He looked up at me, meowing pitifully. A car must have hit it so it wasn’t able to move. I stopped my car and carried the cat in and went on driving.
At the nearest vet clinic, the vet gently examined it. "He's about eight months old and has two broken legs, but I would need X-rays to know how serious the damage is," he told me. "As he's not your cat, I don't know if you want to go ahead with this. It could be rather expensive."
I knew it would cost me hundreds of dollars, but I agreed with his advice. The following morning the vet rang to say the X-rays confirmed two bad breaks in his legs. "I'll operate on his legs and put metal pins in them to keep them fixed." he told me.
That afternoon I went to pick up my little friend. There I could hardly recognize him. His previously dirty fur was now a beautiful silver grey. His front legs were in two casts and he lay there looking at me, purring(發(fā)咕嚕聲) happily.
I thanked the doctor and went out to pay the bill. "I think you've given me the wrong account," I said to the clerk. "This is only $85. He's had X-rays and an operation on his legs." "No, that's right," she replied. "The vet has only charged you for the medication. There's a message on the bottom."
Written under the total were the words "SPECIAL RATE FOR ADOPTIONS." I was speechless at his kind and generous gesture. I paid the account and under his message I wrote "WITH GRATEFUL THANKS, CAT AND MUM."

  1. 1.

    Why didn’t the vet give the cat X-rays immediately?

    1. A.
      The damage was not serious at all.
    2. B.
      The cat was too young to be X-rayed.
    3. C.
      The doctor wasn’t sure whether the author would like to cover the expenses.
    4. D.
      The examination was too expensive for the author to afford.
  2. 2.

    What do we know about the author?

    1. A.
      The author was a caring and generous lady.
    2. B.
      The author often adopted animals.
    3. C.
      The author’s workplace was far from home.
    4. D.
      The author only worked at night.
  3. 3.

    Which of the following is true of the cat?

    1. A.
      He was deserted by his owner and nearly starved to death.
    2. B.
      He was saved on a dark and stormy night.
    3. C.
      He was a lively creature with beautiful brown fur.
    4. D.
      His back legs were broken and had to have an operation.

Howling is a behavior commonly observed among a wolf nark. An animals, wolves work together to hunt and rely on howling was an important means of communication each other. There are different explants of a wolf’s howl and it appears that there may be more to discover.      One theory is that wolves howl to bend better together. It’s almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together . But this theory may be wrong, explains Fred H. Harington, a professor who studies wolf behavior.     Indeed, there have been tines when wolves have been seen one moment howling in a exhorts, and the next, quarreling anions each other. It appears that usually the lowest-tanking menthes of the pack may actually be “punished” for
Joining in the churs at times. So is howling a way to strcagthen a social boad or just a way to reconfirm status among its members? ——Why do welves howl for sure?
What is cleat, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that woloves may separate from one another at times. When this happens, howling appcars to be an ercellent means of gathering.
Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occat in the morning, as if wolves were doing some sotr of “roll rall”where wolves all howl togeter to howl, very likely others will follow.

It was a village in India. The people were poor. However, they were not unhappy. After all, their forefathers had lived in the same way for centuries.
Then one day. Some visitors from the city arrived. They told the villagers there were some people elsewhere who liked to eat frog’s legs. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other places.
This seemed like money for nothing. There were millions of frogs in the fields around, and they were no use to the villagers. All they had to do was catch them. Agreement was reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. For the first time, the people were able to dream of a better future. But the dream didn’t last long.    
The change was hardly noticed at first, but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often, and, there seemed to be more insects around lately.
The villagers decided that they couldn’t just wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides(殺蟲(chóng)劑) and medicines. Soon there was no money left.
Then the people realized what was happening. It was the frog. They hadn’t been useless. They had been doing an important job---eating insects. Now with so many frogs killed, the insects were increasing more rapidly. They were damaging the crops and spreading diseases.
Now, the people are still poor. But in the evenings they sit in the village square and listen to the sounds of insects and frogs. These sounds of the night now have a much deeper meaning

The kids at Shute Country Primary School in Devon are surprisingly quiet when it’s time to go home in the afternoon, instead of the usual shouting and running you can hear them asking each other, “ Are the lights all off?”, “Shall we check the taps in case they are dripping （滴水）?”, “How many paper towels did we use today?”
But it’s not unusual here.The kids have declared a war on waste.
“We’ve never made the children do anything,” explains Liz Templar, the school’s head teacher, “they came up with all ideas themselves.They’re doing this because they want to.”
If you take a look around the school you won’t see anything thrown away unnecessarily.Everything is collected and reused, or sent to be recycled.
Shute School started its green_revolution_two years ago.They looked carefully at every party of school life-from the teaching to the cleaning.They looked at the way stationery（文具） was used-especially photocopying, the way cleaning was carried out, and how food was used and wasted!
Even parents were looked at: how many children came in each car? Did they use unleaded petrol? Could they bring more children in fewer cars?
High on the list was the waste of paper.Next came unfriendly cleaning products.Paper towels were replaced with recycled paper.But the hardest thing for the kids was when they found out how much rubbish was created by the chocolate, crisps and other snacks（小吃） eaten at lunch time.Of their own accord（自愿地）, the children gave them up.Now they bring apples and home-made snacks.
The school has its own garden where they grow vegetables and flowers so that they can learn about the environment.They also use this area for their recycling store-large containers to collect aluminum, bottles, plate and fabric（織物）.
Even the school’s play area is made from recycled things.
Since the children started, the school’s heating and lighting bills have fallen obviously and the number of rubbish bags has gone down from seven a week to two or three.
Everywhere in Shute School there are bright posters asking everyone to take their rubbish home, to save energy and paper and to keep the green flag flying.

    Which of the following best describes the writer’s idea?

After battling hard times and danger for over nine months, British teenager Mike Perham made history last month as the youngest person to sail solo around the world.
The 17-year-old made the record after he cleared the Panama Canal and then sailed through the Caribbean and got home across the Atlantic.
Mike is only three months younger than Zac Sunderland, the 17-year-old American boy who had taken the crown as the youngest solo around-the-world sailor in July.
The two youngsters met in Cape Town in South Africa as they crossed the globe in different directions. Mike insisted they were not rivals(競(jìng)爭(zhēng)對(duì)手). “No. It's two teenagers going out there, living their dream and having the adventure of a lifetime,” he said.
Mike may be young, but he is no stranger to sailing adventures. He picked up the hobby at the age of 6 when his father took him out in a small boat on a local lake. Father and son sailed separate boats across the Atlantic when Mike was 14, making him the youngest person to cross that ocean solo. That record gave him the taste for this even greater challenge.
On the recent journey, the scariest moment for Mike came when his sailboat was hit by storms in the southern Indian Ocean.
“We were picked up by what felt like a 60-foot wave and threw down on our side at 90 degrees,” he said.
“It felt like I was going right over. Stuff was flying around and I just thought ‘Oh no’.”
At other times, he had to dive into the Pacific and fix problems. He tied himself to the boat, jumped into the water and went to work with a knife in 30-second dives underneath the boat to cut a rope away.
Mike said he felt proud that he made his dream come true. “You've got to have confidence in yourself that you will make it,” he said.

With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species(物種). That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.
Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2, 000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”

Mr. Ma, a famous mental doctor from Beijing once said at an important meeting, “Now many young students can have many problems with their minds. Some students become worried because they have to study very hard. Others have trouble getting on well with people around them like their parents and classmates. Parents and teachers should care more about this problem.”
Then Mr. Ma gave some examples. One patient, a middle school student from Xi’an was doing badly in his lessons. He thought his teachers and friends often laughed at him, and he became so nervous and worried that one night he left his home without telling parents. Another student, a 14-year-old schoolgirl from Shanghai, was very afraid of exams. While she was reading the exam paper, she couldn’t think of anything to write.
