1 . It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys’ blood back to the monkeys’ brains. When the brain’s temperature was 10℃, Dr. White stopped the blood to the brain.After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.
1. The brain operation was made possible mainly by ____.| A．taking the blood out of the brain | B．trying the operation on monkeys first |
| C．having the blood go through a machine | D．lowering the brain’s temperature |
| A．can last as long as 30 minutes | B．can keep the brain’s blood warm |
| C．can keep the patient’s brain healthy | D．can help monkeys do different jobs |
a. send the cooled back to the brain b. stop the blood to the brain
c. have the blood cooled down d. operate on the brain

2 . In many countries of the world, people can confidently tell you the meaning of their town or city, but most people who live in Manchester, Oxford or Birmingham would not be able to explain what the name of their city means. The name of every British town and city, however, has a long history.
Two thousand years ago, most people living in Britain were Celts. Even the word “Britain" is Celtic (凯尔特语).Then the Romans arrived and built camps which became cities called “castra". This is why there are so many place names in England which end in "-chester" or “-caster" Manchester, for example.
The Romans never reached Wales or Scotland, and many place names there are Celtic. For example,Welsh place names that begin with “Llan" come from the Celtic word for "church".
After the Romans left Britain, it was attacked by the Anglo-Saxons who were from the area of Europe that is now Germany and Holland. The names of their villages often ended in “-ham" or “-ton". Some got their names from the leader of the village.So Birmingham for example, means "Beormund's village”
The Anglo-Saxons were farmers and the landscape was very important to them, so we have villages called Upton (village on a hill)——a good place to build a village and Moreton (“village by a lake”)where floods could make life hard. Place names that end in “-ford" (a place where you could cross a river) also describe the location of Anglo-Saxon villages.
Finally, in 1066 England became Norman—the Normans gave us the place name "grange", which means farm.
And how about London? Experts cannot agree. The Romans called the city Londinium, but they were not the first inhabitants (居民). People once believed that the United Kingdom’s capital city got its name from the castle of a King called Lud but this is very unlikely. Our best guess today is that the name comes from a Celtic word meaning a fast-flowing river. Like a number of British place names, its history is lost in time.
1. The origin of British place names is unfamiliar to many local people because of| A．the death of local languages |
| B．the long lost history of the names |

| C．Lud | D．Castle |
3 . One advantage of the Internet is shopping conveniently online for clothes; one disadvantage of the Internet is also shopping conveniently online for clothes.
“Nothing fits,” said Lam Yuk Wong, a senior in electrical and computer engineering at Rice University. “Everyone says this. They order clothes and they don’t fit. People get very unhappy.”
Wong and her design partner, Xuaner “Cecilia” Zhang, are Team White Mirror, creators of what they call a “virtual (虚拟) fitting room”. Their goal is simple and consumer-friendly: to let online clothing shoppers have a perfect fit and a perfect look when shopping every time.
Both women are from China, Wong from Hong Kong and Zhang from Beijing. They both order most of their clothing online. They got the idea from their own experience as consumers and from listening to the complaints of friends and relatives. “They say, ‘The color is wrong’ or ‘I got the right size but it still does not fit.’ We want to make it like you’re in the store trying on the clothes,” Zhang said.
Using a Kinect developed by Microsoft for use with its Xbox 360 video game player,
Zhang scans Wong and turns her image into, in effect, a virtual model, keeping Wong’s dimensions (尺寸), and even her skin and hair color. “We put the clothes on the shopper’s 3-D body models and show how they look when they are dressed,” Wong said. So far, Wong and Zhang have adapted the software to show dresses and shirts, and they are now working on shorts.
Asked if she thought men as well as women might be interested in using their virtual fitting room, Wong said, “I think their wives will care about this, so it will also be important to men.”

4 . Xia boyu，70， the first Chinese double amputee （被截肢者） to have reached the top of Mount Qomolangma， the highest mountain in the world， Du Juan reports．
On May 14， 2018， Xia， who is the same age as the People's Republic of china， made his dream come true by reaching the top of Qomolangma （Mount Everest） seven days after leaving Base Camp on the Nepal side of the mountain．
Success didn't come easy． He had failed to reach the 8，844﹣meter peak four times before becoming one of the few double amputees to reach the top of the world．
The first climb by a Chinese team to the peak of Qomolangma was in 1960． Xia， who was born in Chongqing in 1949， was chosen by the Chinese mountaineering team in 1974． In 1975， the second mountaineering team set off． All the teammates finally reached the top， but Xia suffered bad frostbite （W1）in his legs， which had to be amputated at the knees．
"It's beyond imagination how difficult it was to accept the fact that I would suddenly become a disabled person，" Xia recalls． "I could not imagine a future of sitting in a wheelchair， perhaps forever．"
When a doctor told him that with artificial limbs he could live a normal life like anyone else， and he would even be able to do a lot of physical exercise， his hopes rose and he made up his mind to climb Qomolangma again．
To prepare for his fifth attempt（尝试）on Qomolangma， every day he got up at five in the morning and completed 90 minutes of strength training at home． On Mondays， Wednesdays and Fridays he would ride a bike to Fragrant Hills， 30 kilometers from his home， walk to the top and then ride back home． On Tuesdays， Thursdays and Saturdays， he completed 10 km of speed walking．
"Without targets， people lose' direction， "Xia says． So I will keep climbing and contributing more ways to society．"

5 . We are often told to pay attention to what our mothers tell us. Most of us enjoy listening to our mothers speaking. Scientists at Stanford University, US have found that compared to other people’s voices, our brains react strongly to our mother’s voices.
The scientists examined 24 children aged 7 to 12 and asked their mothers as well as two mothers whose children were not studied to record three nonsense words.“In this age period, most children have good language skills. We didn’t want to use words that had meaning because that would have involved(涉及) many different parts in the brain,”said Professor Menon.
The children’s brains were scanned while they listened to the nonsense-word recordings, produced by their own mother and other mothers. Even from very short recordings, less than a second long, the children could make sure of their own mother’s voice with greater than 97 percent accuracy(正确率). Hearing their mother’s voice makes many parts of children’s brains more active, including those about positive emotion and social communication.
Years of study has shown that children prefer their mothers’ voices and it starts even before they’re born. When children are still in the womb (子宫) or have just been born, they hear their mothers talking. This makes babies feel comfortable and safe and teaches them language and social skills, even though they are still very young. Later, when this sound is heard again, more attention is paid to it.
1. How many mothers were invited to enter the study?| A．12. | B．24. | C．26. | D．48. |
①Scientist scanned children’s brains.

6 . Meg. Jo, Amy and Beth live with their mother Mrs. March while their father is fighting in the Civil War. The family doesn’t have much money. They live next door to M. Laurence, who is very wealthy, and his grandson, Laurie. The passage below is about Beth, who loves to play the piano. The March family only has a small, out-of-tune piano. The “Mansion of Bliss” is Mr. Laurence’s house.
But Beth, though dying for the grand piano, could not gather courage to go to the Mansion of Bliss’. She went once with Jo; but Mr. Laurence, not being aware of her weakness, stared at her so hard from under his heavy eyebrows, and said “Hey!” so loud, that he frightened her so much, her feet chattered on the floor, she never told her mother; and she ran away, declaring she would never go there any more, not even for the dear piano. No comfort could overcome her fears, till the fact coming to Mr. Laurence’s ear in some way, he set about mending matters. During one of the brief visits he made, he artfully led the conversation to music, and told such attractive stories that Beth found it impossible to stay in her distant corner, but moved nearer and nearer, as if interested. At the back of his chair she stopped, and stood listening with her great eyes wide open, and her cheeks red with the excitement of this unusual performance. Taking no more notice of her than if she had been a fly, Mr. Laurence talked on about Laurie’s lessons and teachers: and as if the idea had just occurred to him, he said to Mrs. March:
“The boy pays little attention to his music now. But the piano suffers for lack of use. Wouldn’t some of your girls like to run over, and practise on it now and then, just to keep it in tune, you know, madam?”
Beth took a step forward, and pressed her hands tightly together to keep from clapping them and the thought of practising on that splendid instrument quite took her breath away. Before Mrs. March could reply, Mr. Laurence went on: “They needn’t see or speak to anyone, but run in at any time: for I’m shut up in my study at the other end of the house, Laurie is out a great deal, and the servants are never near after nine o'clock.”
Here he rose, as if going. “Please tell the young ladies what I say; and if they don’t care to come, why, never mind.”
“Oh, sir, they do care, very, very much!” Beth finally made up her mind to speak, in her eager yet shy way.
“Are you the musical girl?” he asked, without any frightening “Hey!” as he looked down at her very kindly.
“I’m Beth. I love it dearly, and I’ll come, if you are quite sure nobody will hear me-and be disturbed,” she added, fearing to be rude, and trembling at her own courage as she spoke.
“Not a soul, my dear. The house is empty half the day; so come as much as you like.”
“How kind you are, sir!”
Beth blushed like a rose under the friendly look he wore; but she was not frightened now, and gave the big hand a grateful squeeze, because she had no words to thank him for the precious gift he had given her.

Phew! I'm so glad the day is over. I'm really tired, but my first day at school went well.
First of all, we met outside the school building.I was very nervous because my primary school only had 300 pupils but in the middle school there are about 1,300.What a difference! The older pupils are really big.I felt so small waiting there in front of the school.
The head teacher came out and told us to go into the school hall.Then he called our names out to tell us which class we were in. My class teacher is called Mrs. Black. She took us to our classroom.It's on the 5th floor.We aren't allowed to use the lift! I couldn't believe it.
We spent all morning with Mrs.Black looking at our timetables.Everyone in the school had a different timetable.I'm worried that I'll forget my timetable and go to the wrong room.
Lunchtime was OK. I had salad, fish and fruit, which was quite good, and then I went to play football with some of the other boys. They were all friendly and I don't think it will take me long to make friends.
After lunch we started lessons. I had maths and then history, where we started to learn about ancient Greece.That looked interesting.I have to do some homework tonight to find out how the ancient Greek people lived, so I'm going to do an Internet search and look it up in the library.
So far so good.I am quite looking forward to tomorrow, even though I've got science. I hate science!
Yours,
Jason

8 . An elm tree (榆树) was planted in the first half of the 20th century on a farm in Michigan, US.
In the 1950s, the family that owned the farm kept a bull chained to it. The bull walked around the tree. pulling a heavy iron chain, which made a grove (沟) in the tree about a meter off the ground. The groove deepened over the years, thought for whatever reason, it didn’t kill the tree.
After some years, the family sold the farm and took their bull with them. They cut the chain, leaving most of it hanging down from the tree. Eventually, bark (树皮) slowly covered the old chain.
Then one year later, disaster struck Michigan in the form of Dutch elm disease. It left a path of death across vast areas. All of the elms lining the road leading to the farm were infected and dies. Everyone figured that the old elm tree would be next. There was no way the tree could last, with its age and the chain hanging off its trunk.
The present owners considered pulling the chain out and chopping the tree up into firewood before it dies. But they simply couldn’t bring themselves to do it. It was as if the old tree had become a family friend, so they decided to let nature take its course. Amazingly, the tree didn’t die. Year after year, it grew stronger. Nobody could understand why it was the only elm still standing in the whole area.
Experts from Michigan University came to observe the tree later examining the scar left by the iron chain. The experts decided that it was actually the chain that saved the elm’s life. They reasoned that the tree must have absorbed so much iron from the chain that it became immune to Dutch elm disease.
It’s said that what doesn’t kill you will make you stronger. So if you’re ever in Michigan, look for that beautiful elm tree. Look for the wound made by the chain — it serves as a reminder that even with wounds, we can still have hope. Our wounds can give us the resources we need to cope and survive. They can truly make us strong.

9 . A 1400-year-old Peruvian method of diverting (转向) water could supply up to 100 million cubic meters of water—equal to 40,000 Olympic-size swimming pools' worth of water—to Lima each year, according to a new study published in Nature Sustainability. It's one example of how ancient methods could support existing modern ones in countries without enough water.
More than a billion people across the world face water shortages. Man-made reservoirs store rainwater and water overflow for use during drier times. But reservoirs are costly, require years to plan and can still fail to meet water needs.
Peru's capital, Lima, depends on water from rivers high in the Andes Mountains. It takes only a few days for water to flow down to the city. So when the dry season begins in the mountains, the water supply quickly disappears. The city suffers shortages of 43 million cubic meters during the dry season. It solves this with modern structures such as man-made reservoirs. These reservoirs are not the only solution, however. Over a thousand years ago, indigenous (本地的) people developed another way to solve water problems.
Boris Ochoa-Tocachi is a researcher at Imperial College London and lead writer of the study. He explored one of the last remaining water-harvesting systems in the small mountain community of Huamantanga, Peru. The system was developed even before the ancient Inca civilization.
The 1,400-year-old system is designed to increase the water supply during the dry season by diverting and slowing water as it travels down the mountains. This nature-based method is made of special canals that guide water from its source to a series of water bodies and hillsides. The water goes slowly into the ground, then flows downhill through the soil and reappears in water bodies near the community.
The researchers measured how much the system slowed the flow of water by injecting special dye in the highlands and noting when it reappeared in water bodies. The dyed water started to surface two weeks later and continued flowing for eight months—a huge improvement over the hours or days it would normally take.

10 . When I was about twelve, I headed to a restaurant for dinner with my family. It was a windy winter night. As my mom and I headed towards the restaurant from our car, a girl about my age and her mother came up to us. They asked if we had any spare dollars. My mom immediately asked where they kept their things. They pointed to an old car in the parking across the street. The girl said there were six of them living in that car, the same size as my own family.
My mom said she had something to do after handing the people a few dollars. She sent me inside the restaurant with my dad and my three siblings(兄弟姐妹). But she didn’t come.
Later, I found out she had gone home and emptied our cupboards into a few bags. Then, she brought that food over to the car and handed the bags to the family. I wasn’t there when that part happened, but I could imagine the joy it brought to their faces.
A few days later, when I actually found out about what she had done, I asked her why she helped those people. She told me that they were not lucky. I remember the face of that girl who had asked us for dollars;she was the same age as me, yet our lives were so different.
Here I stood, dressed in almost new clothes, headed to a restaurant and then back home to the bedroom I shared with my younger sister. I remembered thinking that the girl didn’t have any food to eat and that she was heading back to a cold car shared with five other people.
After painting this picture in my mind, I understood my mom. I will never forget what she did that night. And that night I also learned one of the best lessons she taught me.
