The Intel Science Talent Search is the top science competition for high school students in the US. The 40 finalists were honored in Washington last week. They met with scientists and politicians. President Obama welcomed them to the White House.
These 40 students were selected from almost 2,000 contestants nationwide. They had to present original research to be judged by professional scientists. The students showed their research projects on large posters. The winners were announced on March 15th, 2011.
Wendy Hawkins is executive director of the Intel Foundation, who says the 40 finalists represented excellence across many areas of science.
Selena Li is from Fair Oaks, California. She wanted to find a more effective treatment for liver cancer. She began her research four years ago. A scientist at the University of California, Davis, taught her how to design and do experimental work in the laboratory. Ms. Li placed 5th in the Intel Science Talent Search and was awarded 30,000 dollars.
Scott Boisvert lives near Phoenix, Arizona. He began using a laboratory at the University of Arizona at the age of 14. Over four years, he completed a project studying a fungus(真菌) linked to the decrease in amphibians（两栖动物）around the world. He was trying to find out if different chemicals and substances in the water could kill the fungus. He collected and tested water samples across Arizona. He says, “My results were able to identify a list of chemicals that were significant in the growth and in the movement of the fungus.” He placed10th in the Intel competition and was awarded 20,000 dollars.
Evan O’Dorney of Danville, California, won the top award of 100,000 dollars in this year’s Intel Science Talent Search. For his mathematical project, he compared two ways to estimate the square root of an integer (整数) , a number with no fractional parts.

“If you want to see a thing well, reach out and touch it!”
That may seem a strange thing to say. But touching things can help you to see them better.
Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass is. When you feel all these about the ball, you really see it. With your skin, you can feel better. For example, your fingers can tell the difference between two coins in your pocket. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music.
All children soon learn what “Don't touch!”means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things we might buy: food, clothes. To see something well, we have to touch it. The bottoms of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a hard floor. All feel different under your feet.
There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them!
Most museums are just for looking. But today some museums have some things to touch. Their signs say, “Do touch!” There you can feel everything on show.

| A．you will have a strange feeling |
| B．you will learn how to reach out your hand |
| C．you can learn more about them |

Which of the following can be the best title of the story?
| A．Touching by Feeling | B．To See or to Feel |
| C．To See Better—Feel | D．Ways of Feeling |

Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time; if corrected too much, he will stop talking. He notices a thousand times a day the difference between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people’s. In the same way, children learn to do all the other things without being taught to walk, run, climb, whistle, ride a bicycle…They compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes and correct them for himself. We do it all for him. We act as if we thought that he would never notice a mistake. If it is a matter in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time in such routine(日常的) work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer. Let the children learn what all educated persons must some day learn, how to measure their own understanding, how to know what he does not know.According to the passage, the best way for children to learn things is by_____.
| A．listening to skilled people’s advice. |
| B．asking older people many questions |

There have been big changes in the attitudes of most parents over the last few years. Physical punishment is banned in schools in most countries ,and in many countries, there are moves to ban all physical punishment of children even at home. However, many parents still believe that they have the right to use some physical punishments to deal with certain misbehavior at certain ages.
It ‘s easy to find reasons to allow some physical punishments. One issue is that many parents find it very difficult to abandon physical punishment completely. Parents argue that this was the way they were brought up and that it didn’t do any harm to them. They believe that for the child’s sake they have the right to discipline the child in any way they consider fit ，including using some physical punishments. The other one is that physical punishment can be quick and effective. There is not much point reasoning with a screaming child in the supermarket.
However, there are several reasons why we should stop using physical punishment. One point is that most parents are not trained to deal with misbehaving children. They don’t have enough resources or choices to handle the situation. As a result, they immediately react by hitting the child even if there are other solutions to the problem. Another point is that unless people are challenged or forced to change their belief, they may keep following negative habits. An example is seat belt use ——now most people wear seat belts without thinking, while years ago the idea of using seat belts was strange to most people. In the same way, banning physical punishment will force people to change their habits.
In conclusion, parents have to change some of their belief and ideas about how children should be raised. It is possible to avoid the use of physical force,and doing so will help us move closer to the dream of removing violence from our society.According to the first paragraph, many parents think that _____
| A． they are free to use physical punishment on their children |

Many parents won’t give up physical punishment because _____.
| A． they are disappointed with their children |
| B． they were brought up just in the same way |
| C． they don’t want to hurt their children badly |
| D． they don’t know what to do with their children |

| A． most people are used to wearing seat belts |
| B． it’s not difficult to change some negative habits |
| C． seat belts are really very necessary and useful |
| D． people won’t change their old habits unless forced |

“ Dining out”, or “ eating out ”,is a phrase people use in Britain when they eat in a restaurant or a pub. Eating out is more popular in Britain today than ever before.
However, eating out can be expensive. Restaurants are normally more expensive than pubs, though many pubs serve very good ，simple food. As British people don’t dine out every night of the week ,eating in a restaurant is often seen as a special occasion. When going for the first date， or if celebrating an anniversary or a birthday, many people like to go to a restaurant. People often eat in a restaurant before going to the cinema or the theatre.
As in all cultures, there are many rules of etiquette (礼节)surrounding food and eating, and nowhere is this more pronounced than when eating in a smart restaurant. People are almost always expected to eat with a knife and fork and these should be held in the correct hand and used in the correct way. It is also impolite to have your elbows on the dining table when you are eating.
There’re many such “unspoken” rules — they are normally only important when eating in a very elegant and expensive restaurant, and vary slightly from restaurant to restaurant and place to place. A recent nationwide survey showed that there was a divide in manners between the north and south of Britain ---the “worst” manners were in Scotland and the northeast, and the “best” in Wales and the southeast! However, this survey was almost certainly conducted by someone in the southeast, so it may not be entirely fair.
Naturally, restaurants vary greatly in quality and price. However, almost all British cities have a vast range of food and cooking styles to choose from as well as traditional British food, from the very cheap to the very expensive — French, Italian, Indian, Greek, Thai, Japanese and many more. In fact, when asked what their favorite food is, many British people say an Indian curry (咖喱菜)rather than any other dish!
As well as dining in a restaurant ，when people are too tired to cook after work they often get a “takeaway”. This means they order from a takeaway or takeout restaurant by phone, then go to collect it and take it home to eat. Many takeout restaurants also deliver to your house. While you can normally find a takeout restaurant for almost any cuisine, the most popular are Italian, Indian and Chinese — and all you have to do is to open the door, pay and eat! What can be concluded from the first two paragraphs?
| A． The British spend more eating out than cooking at home. |
| B． The British pay great attention to eating in a restaurant. |
| C． The British often dine out when celebrating festivals. |
| D． People tend to eat in a restaurant after watching a movie. |
The underlined word “pronounced" in Paragraph 3 probably means “_____
| A． polite | B．expensive | C．strange | D．obvious |
According to the passage, which of the following statements is true?
| A． There exist great differences of rules in different restaurants. |
| B． People from Wales and southeast Britain are the most polite. |
| C． Your order in a takeout restaurant can be sent to your home. |
| D． Traditional British food is seldom served in British restaurants. |
What does the passage mainly talk about?
| A．Restaurant culture in Britain. |
| B．Table manners in Britain. |
| C．Different restaurants in Britain. |
| D．Traditional and foreign foods in Britain. |
Back those photos up
The images were striking. Homes on the East Coast were washed away by Super storm Sandy. People were in tears, picking up faded photographs, among their only remaining possessions.
If that doesn’t move you to get serious about safekeeping your lifetime of memories, what will? The digital age offers tools never imaginable before—including one-click access to a lifetime of family photos.
Here is a brochure on how to back up (存) your photos and save them online, where they can live forever and be accessible in good times and bad.
Scanning
The first step for those old photos is to scan them and save them to a digital format. Most printers come with scanners these days, so that’s an easy but extremely time-consuming step.
Storing the photos
With your scans in place, import the photos into your computer, and back them up.
You could make multiple copies of the disks and spread them to loved ones. Or you could choose external(外接的) hard drives or USB thumb drive, and add your photo and video collection from your computer.
Online backup
If you need lots of space, look at a pure online backup service, Caronite.
Caronite backs up 300 million files daily. Once you sign up, it starts to pick up everything you have on your hard drive. But photo collection on your computer’s main hard drive charges for $59 a year.
Cloud Storage
For folks who don’t need automatic backup, but instead want to take a more active approach, Dropbox, Google Drive and Microsoft’s Sky Drive let you store files online by yourself, share and instantly access them. All offer free options—2GB of free storage for Dropbox, 5GB for Google and 7GB for Sky Drive. But if you want more, you need to pay.
Bottom Line
The hard drive or flash drive is the cheapest and easiest. But drives can fail. Online services are more expensive, but more secure. With more of us switching back and forth between our computers, such services are the best way to get access to our data from wherever we are. Why does the author mention Super storm Sandy?
| A．To tell the background of the scanning photos. |
| B．To describe a severe natural disaster. |
| C．To attract the readers’ interest in the backups. |
| D．To win the readers’ sympathy. |
What can we know from the passage?
| A．Scanning photos take little time but costs a lot. |
| B．Caronite charges for backing up photos from hard drive. |
| C．Google Drive offers unlimited free photo storage on line. |
| D．The hard drive or flash drive is the cheapest and safest. |
Which of the following allows storing files automatically?
| A．Dropbox. | B．SkyDrive. | C．Caronite. | D．Flash drive. |
The main purpose of the passage is to _____.
| A．introduce some of the storage services |
| B．tell real stories about storage services |
| C．describe the functions of storage services |
| D．argue about the advantage of storage services |
