What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate(调查),how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations. Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.What makes a scientist according to the passage?

There’s a guy like me in every state and federal prison in America, I guess — I’m the guy who can get these for you: cigarettes, a bag of cigar, if you want that, a bottle of wine to celebrate yourson or daughter’s high school graduation, or almost anything else. . . within reason, that is. It wasn’t always that way.
I came to Shawshank when I was just twenty, and I am one of the few people in the prison who is willing to admit what he did. I committed murder(谋杀). I put a large insurance policy(保险单) on my wife, who was three years older than I was, and then I fixed the brakes of the car her father had given us as a wedding present. It worked out exactly as I had planned, except I hadn’t planned on her stopping to pick up the neighbor woman and the woman’s son on the way down Castle Hill and into town. The brakes let go and the car crashed through the bushes, gathering speed. Bystanders said it must have been doing fifty or better when it hit the base of the Civil War statue in the town arid burst into flames.
I also hadn’t planned on getting caught, but I was caught. I got a pass into this place. My state has no death penalty(死刑), but I was tried(审判) for all three deaths and given three life sentences, to run one after the other. That fixed up any chance of parole(假释) I might have, for a long, long time. The judge called what I had done ‘an extremely evil(邪恶的) crime’, and it was, but it is also in the past now.
Have I transformed myself, you ask? I don’t know what that word means, at least as far as prisons and corrections go. I think it’s a politician’s word. It may have some other meaning, and it may be that I will have a chance to find out, but that is the future. . .
I was young, good-looking, and from the poor side of town. I met a pretty, headstrong girl who lived in one of the fine old houses on Carbine Street. She got pregnant(怀孕的) later. Her father was agreeable to the marriage if I would take a job in the company he owned and ‘work my way up’. I found out that what he really had in mind was keeping me in his house and under his thumb, like a disagreeable pet that has not quite been housebroken and which may bite. Enough hate eventually piled up to cause me to do what I did.
Given a second chance I would not do it again, but I’m not sure whether that means I am transformed.What do we know about the man from the passage?

Bigger-brained birds survive better than their feathered friends with smaller brains, according to a study published on Tuesday.
Scientists have suspected that birds with large brains in relation to their body size lived longer because they were able to adapt their behavior to environmental challenges.
Now they have provided evidence that it does.
“We have tested the hypothesis(假设) that the brain can buffer(缓冲) animals against the environment and help them to survive when they face environmental challenges,” said Daniel Sol of the Centre for Ecological Research and Forestry Applications in Barcelona, Spain.
After comparing death rates, brain size and body mass of 236 species of birds from different regions of the world, Sol and scientists in Britain, Hungary and Canada discovered that the bigger the brain the better. Crows and parrots have the largest brains, while pheasants (野鸡) have a relatively small brain.
Earlier studies have shown there is a relationship between the size of the brain and an animal’s capacity to create new behavior and adapt more easily.
“The idea is that if you have a big brain, you are more capable of adjusting behavior and responding to environmental changes. This can help you to survive,” said Sol, who reported the finding in the journal Proceedings of the Royal Society B: Biological Sciences.
Tamas Szekely of the University of Bath in England and a co-author of the report, said birds were ideal to test the hypothesis because they are the only species in which brain size and behavioral response to environmental challenges such as climate and habitat destruction is understood.The finding of bird’s brains recently refers to ________.
| A．the smaller brain the birds have, the longer they live |
| B．the smaller brain the birds have, the cleverer they are |
| C．the bigger brain the birds have, the larger their bodies are |
| D．the bigger brain the birds have, the abler they are to deal with environment |
Scientists from ________ countries have made the discovery.
| A．two | B．three | C．four | D．five |
According to the text we can know that the report of the finding was written by________.
| A．Daniel Sol |
| B．Tamas Szekely |
| C．Daniel Sol and Tamas Szekely |
| D．someone whose name was not mentioned |
Which of the following statements is true?
| A．Pheasants have the smallest brains of all birds. |
| B．Crows and parrots have the largest brains in all animals. |
| C．A pig’s brain is bigger than a cock, so it must be cleverer than the cock. |
| D．The discovery is now only certain about and mainly limited to birds. |
Micro bloggers: don’t be too excited if you have more fans than your friends on your Sina Weibo or Tencent micro blog—some of them might be “zombie fans”, or fake(假的) followers.
That’s what Chen Chuanliang, creator of Leijian Network, found when he bet against his friend several months ago. Chen, who used to do data mining for Microsoft Asia Research Institute, discovered that there were far more invalid(无效的)micro blog accounts than he had imagined.
Later Chen picked 10 users on Sina Weibo and analyzed their statistics. Kai-Fu Lee, the former CEO of Google China, who’s on Chen’s list of research, posted a message on his micro blog after he found out that he had more than 1 million fake fans(out of about 5 million), joking “I have 1 million zombie fans? If united, we can finally defeat those plants.”
According to a report by S Weekly in March, zombie fans on micro blogs are defined as invalid accounts signed up by network companies for the purpose of increasing the number of fans for certain users and getting them more attention.
And this kind of fake followers are also very much alive on Western social networks such as Twitter and Facebook.
The Financial Times reported in August，that Newt Gingrich，a Republican candidate in the US presidential election, bought about 80 percent of his 1.3 million Twitter followers and tried to use them as help in his campaign.
Now there are also business deals through which users can get hundreds of thousands of fans for their micro blog accounts, by paying a small amount of money.
“We have been working to find ways to block or delete those invalid accounts,” Mao Taotao, a spokesperson for Sina Weibo told S Weekly.
“But as the fake accounts grow so fast, they’re going to be here for a while.”
Which of the following might be the best title for the passage?
| A．Micro Bloggers | B．Blog Accounts |
| C．Zombie Fans | D．Micro Blog Fans |
Users get zombie fans for their micro blog accounts by________.
| A．making friends with people |
| B．paying a little money |
| C．helping their weibo followers |
| D．doing search on the Internet |
It can be learnt from the passage that________.
| A．there are more fake fans in America than in China |
| B．invalid accounts for micro blogs will be deleted in no time |
| C．there exist many fake fans on western social networks as well |
| D．Newt Gingrich had 1.3 million followers in his presidential election |
The underlined word “their” in the passage refers to ________.
| A．deals’ | B．fans’ |
| C．campaigns’ | D．users’ |
You will enjoy a wonderful summer vacation with these easy tips.
1. Fly into Alternate Airports
Most major destinations are served by more than one airport. Flying into a less popular one can result in cheaper tickets. Another added perk of quieter airports? Shorter check-in and security lines, and less waiting around.
2. Use Public Transportation for City Travel to Save Time and Money
When possible, take public transportation from the airport to your hotel. For example, the London-Heathrow express train takes just 15 minutes to get from airport to city and costs under 20 pounds. By contrast, “A taxi costs about 70 pounds and takes 40 minutes,” reports DiScala.
3. Eat Smart, Explore…and Save
Look for ways to take your order in pricey restaurants and you can avoid “Are we about to run out of money?” “Don’t order an appetizer. Don’t drink a lot of booze,” says DiScala.
Also, cover more ground by spreading out your snack places. “Have dessert at a café or ice cream stand, instead of at the dinner restaurant,” suggests DiScala. You’ll see more of the city and decisions about where to go for dinner will be less worrying.
4. Hit the Market
Much like reading the local newspaper, visiting a market gives context to a foreign country. Even the smallest villages tend to have a weekly open-air market(often on Saturday mornings), while in larger towns and cities, expect additional market days, as well as big supermarkets.
Markets also sell amazing, wallet-friendly souvenirs. Think about sea salt, local spices or sauces, and regional oils and vinegars. Eatable gifts are almost always appreciated, saving you the stress of finding the “perfect” gift for each person on your list.The passage aims to tell the readers how to________.
| A．take a plane without waiting for long |
| B．spend your holidays abroad economically |
| C．eat in a pricey restaurant at the smallest expense |
| D．save money to buy eatable gifts in a foreign market |
What does the underlined word “perk” in Line 4 mean?
| A．Special benefit. | B．Strict standard. |
| C．Common scene. | D．Extra trouble. |
Which of the following will best help you save time and money?
| A．Choosing a bigger airport. |
| B．Visiting local markets. |
| C．Having dinner at the hotel. |
| D．Taking an express train. |
What can be inferred from the passage?
| A．Having coffee at a cafe will cost more money. |
| B．Souvenirs bought at local markets are expensive. |
| C．You will run out of your money if you eat out. |
| D．Markets help you understand your tourist destination. |
As an American artist and writer of children’s books, Tasha Tudor’s art and nineteenth-century lifestyle have fascinated adults and children for decades. She received many awards and honors for her contributions to children’s literature. When people talk about her creativity in artwork, she said, “I do it to support my dogs and my four children.” Her great publishing record, the number of magazine stories that have been written about her over the years, and her admirers have no effects on her at all.
Much of Tasha’s artwork and her reading are done in the wintertime. “I love winter. It’s delightful,” she says. “I don’t have to go anywhere because I work at home. If I’m snowed in, I can stay this way for months.” She hopes for early, deep snow to protect her garden from the hardship of the New England winter, and when it comes she puts on snowshoes when she needs to get down the mile-long dirt path that leads to the road.
Given her enjoyment of winter and her fantasy(梦幻)way of life, it’s not surprising that Tasha’s Christmas is a storybook holiday. She hangs flowers over the front door. Her tree comes from the woods, and it goes up on Christmas Eve, lit by homemade candles and decorated with her great- grandmother’s collection that dates from 1850. In a place of honor on the tree are large cookies cut into the shapes of her animals.
The grandchildren and friends get presents from Tasha’s old dolls; so do the animals and they have their own Christmas tree. “Of course, it’s a known fact that all the animals talk on Christmas Eve,” she has written. Small, handmade gifts fill a big wooden box.
At the end of each year, Tasha can look back and know that her life is perfect, that she has again ignored the twentieth century, and that the magic continues. And for the rest of us，here’s a bit of advice, Tasha style: “Nowadays, people are so restless. If they took some tea anti spent more time rocking on the porch(门廊) in the evening listening to light music, they might enjoy life more.”
