Wikipedia is a free-access, free content Internet encyclopedia(百科全書), supported and hosted by the non-profit Wikipedia Foundation. Wikipedia is ranked among the ten most popular websites and is considered the Internet’s largest and most popular general reference book. Now, Wikipedia is becoming Wookiepedia as scientists hope the informative website will help us reach out to intelligent life forms. So aliens can learn about the human race.
Astronomers would like to beam (播送) the entire contents of Wikipedia into space in the hope of contacting aliens. They want to send messages to hundreds of star systems and planets 20 light years away using radio telescopes. The Search for Extraterrestrial Intelligence Institute, in California, wants to use powerful radio telescopes to try to reach Chewbacca and his mates in a galaxy(銀河系)far away.
The plans will be discussed by astronomers at the weekend as some scientists fear the reply from ET might not turn out to be friendly. Institute scientist David Black said, “One question is if there are dangerous creatures we might be drawing their attention to ourselves. Another is if we go ahead, what message should be sent? There could be many civilizations out there,but if they are all listening and no one is broadcasting or responding, then nothing will happen.”
Professor Stephen Hawking, who has warned that intelligent aliens probably exist and we should keep a safe distance from them, is among those. “If aliens visit us, the outcome would be much as when Columbus landed in America which didn’t turn out well for the Native Americans,” he said.
Signals from Earth’s radio and TV broadcasts have been heading out in space for some 60 years reaching around 5,000 stars.
1.What does the underlined word those in the fourth paragraph refer to?
A. aliens from space
B. astronomers sending signals
C. scientists for the plans
D. scientists against the plans
2.What has Prof. Stephen Hawking warned?
A. intelligent aliens would probably land in America.
B. the plans will be in vain and nothing will happen.
C. none of the civilizations would reply.
D. aliens would bring disasters to the human race.
3.Which can be the best title?
A. Wikipedia, the most popular website
B. Wikipedia to be beamed into space
C. Wikipedia, aliens’ best friend
D. Wikipedia to result in a disaster

If you have a bad habit of losing things, a new device that can be connected to any item that you might lose may be the way to solve your problem. The Tile, a small square linked up to your iPhone or iPad via Bluetooth, lets you see how close you are to the missing item, within a 50-to 150-foot range . If the item goes out of your phone’s 150-foot range, it can still be detected (發(fā)現(xiàn)) on other smartphones with the same app.
When you log into the app on your phone, it shows you, with green bars that increase or decrease, how far away you are from the Tile. You can also program it to make a sound when you get close to the Tile. And you can link up your phone with up to ten Tiles. And if your lost item — a dog, for example, or a stolen bike — goes out of your own phone’s 150-foot Bluetooth range, you can set it as a “l(fā)ost item”. If any of the phones with the Tile app comes within the range of your lost item, a message will be sent to your own phone, reminding you of its position. The Tile app also has the function to remember where it last saw your Tile, so that you can easily find where you left it.
Since the Tiles use Bluetooth rather than GPS, they never run out of battery or need to be charged, and they last for one year before needing to be replaced. The app, which will come into the market this winter, works with iPhone 5S, iPhone 6, iPad Mini, iPad 3rd and 4th generation, and iPod 5th generation.
1.The Tile app can help you .
A. find your missing items
B. use your phone more wisely
C. save your phone’s battery power
D. connect something to your phone
2.Which of the following is TRUE according to the passage?
A. The Tile needs to be charged after a year of use.
B. One smartphone can only be linked up to one Tile.
C. The Tile cannot work when linked up to a phone without Bluetooth.
D. A missing item can’t be found if it goes out of the needed range.
3.What does the second paragraph mainly tell us?
A. What the Tile app is.
B. How the Tile app works.
C. The advantages of the Tile app.
D. Why the Tile app was invented.
4.Where does this passage probably come from?
A. A science fiction novel.
B. An advertisement.
C. A personal diary.
D. A news report.

It's reported that many people died of traffic accidents each year. Road safety has aroused the widely attention of the public. Many rules have made to reduce the traffic crashes, especially for the ones involved in the pedestrians. In my opinion, we should make road safety seriously in our daily life. While used the road, we must walk on the pavement and learn to protect us. Besides, car drivers should obey the traffic rules, that is both good for themselves and others.
In the word, obeying the traffic rules are what all of us should pay attention to particularly. After all, life is not a small matter.

Anyone who has worn a cast (石膏) knows that rebuilding muscle strength once the cast is removed can be difficult. Now researchers at the Ohio Musculoskeletal and Neurological Institute (OMNI) at Ohio University have found that the mind is critical in maintaining muscle strength following a long period of not moving and that mental imagination may be key in reducing the associated muscle loss.
Strength is controlled by a number of factors----the most studied by far is skeletal muscle. However, the nervous system is also an important, though not fully understood, determining factor of strength and weakness.
Brian C. Clark and colleagues set out to test how the system functions in strength development. They designed an experiment to measure changes in wrist (腕) muscle strength in three groups of healthy adults. Twenty-nine subjects wore a hard cast that extended from just below the elbow (肘) past the fingers, effectively preventing the hand and wrist from moving, for four weeks. Fifteen subjects who did not wear casts served as the control group.
Of the 29 people wearing a hard cast, half were asked to regularly perform an exercise, imagining they were strongly contracting their wrist for five seconds and then resting for five seconds. This was repeated four times in a row followed by a one-minute break for a total of 13 rounds per session and five sessions per week. The other half performed no imagination exercises.
At the end of the four-week experiment, both groups who wore casts had lost strength in their unmoving limbs (肢體) when compared to the control group. But the group that performed imagination exercises lost 50% less strength than the non-imagination group. The nervous system’s ability to fully make the muscle recover also returned more quickly in the imagination group compared to the non-imagination group.
1.What does the underlined word “critical” mean in the first paragraph?
A. Serious. B. Disapproving.
C. Significant. D. Criticizing.
2.Which of the following statements is NOT true according to the passage?
A. Scientists have partly understood the nervous system.
B. Whoever has worn a cast for long may have difficulty in muscle recovery.
C. Scientists have already spent a lot of time in studying skeletal muscle.
D. The number of the subjects in the experiment was 29 in all.
3.What can we learn from the experiment?
A. The control group lost 50% less strength than the non-imagination group.
B. The imagination group lost more strength than the non-imagination group.
C. The control group wore casts but didn’t perform the imagination exercise.
D. The speed of non-imagination group’s muscle recovery was slower.
4. Where can you most probably find the passage?
A. In a science magazine. B. In a storybook.
C. In a textbook . D. In a book review.

I the book from the floor and opened it, turning the pages, searching for my name, that I would discover dirty and ill speaking of me. However, as I read, the blood ran from my face. It was worse than I . There was a brief description of herself, her goals and her dreams followed by a short portrayal (肖像) of the person who has her most. I started to cry. I was her . She admired me for my personality, my achievements and red-facedly, my .
I stopped reading, struck with the I had done. I had wasted so much energy pushing her away I had missed out on her. Those sincere words she wrote seemed to break an icy around my heart and I longed to know her again.
On that fateful afternoon, as I put aside the laundry and rose to my feet, I decided to go to her—this time to experience to judge, to hug rather than fight. After all, she was my sister.

Tomorrow's World Book Day has inspired a slew of literary events throughout the capital. Xing Yi and Liu Zhihua report.
As World Book Day, April 23, approaches, various reading events are being held by government agencies, libraries and bookstores throughout the capital.
At the launch of the 5th Beijing Reading Season in Great Canal Park in Tongzhou district on Saturday night, 81-year-old Yin Zhiguang, head of Beijing Elocution Troupe, led the audience in reciting a poem.
Activities focusing on different readerships will highlight World Book Day in bookstores throughout Beijing, such as picture book sharing for children in Xidan Book Building, conversations with musicians and authors for young people in Sanlian Bookstore, talks with diplomats for people interested in international affairs in Wangfujing Xinhua bookstore, and a 12-hour late-night reading marathon for night owls at One-Way Space bookstore.
Recently, we conducted a survey about how many extra-curricular books students read per year. On average, each student read 5.34 books, which is definitely not adequate compared with their counterparts from the Western countries. It is upsetting to see the outcome. When asked what students in our school do in their spare time, they claim that they tend to watch TV and surf the Internet, for they can have great fun. Some students even complain that they are forced to attend some extra make-up classes so that they have no time to play, not to mention reading books.
School authority is planning to launch a campaign to encourage students to read more extra-curricular books.
