Wikipedia is a free-access, free content Internet encyclopedia(百科全书), 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(银河系)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.
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

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.

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

Thinking is something you choose to do as a fish chooses to live in water. To be human is to think. But thinking may come naturally without your knowing how you do it. Thinking about thinking is the key to critical thinking. When you think critically, you take control of your thinking processes. Otherwise, you might be controlled by the ideas of others. Indeed, critical thinking is at the heart of education.
The word “critical” here has a special meaning. It does not mean taking one view against another view, as when someone criticizes another person for doing something wrong. The nature of critical thinking is thinking beyond the easily seen — beyond the picture on TV, the untrue reports in the newspapers, and the faulty reasoning.
Critical thinking is an attitude as much as an activity. If you are curious about life and desire to dig deeper into it, you are a critical thinker. If you find pleasure in deep thinking about different ideas, characters, and facts, you are a critical thinker.
Activities of the mind and higher-order reasoning are processes of deep and careful thinking. They take time, and do not go hand in hand with the fast speed in today’s world: fast food, instant coffee, and self-developing film. If you are among the people who believe that speed is a measure of intelligence, you may learn something new from a story about Albert Einstein. The first time Banesh Hoffman, a scientist, was to discuss his work with Albert Einstein, he was too nervous to speak. But Einstein immediately put Hoffman at ease by saying, “Please go slowly, I don't understand things quickly.”
69. According to the passage, if we don’t think critically, we ___________.
A. may not be able think naturally
B. will be controlled by ideas of other people
C. can control the ideas of others
D. might be fooled by other people
70. A critical thinker will ___________.
A. think deeply about different ideas B. trust the reports in the newspapers
C. take one view against another view D. criticize other people for their mistakes
71. What would be the best title for the passage?
A. The heart of educationB. Understanding critical thinking
C. Thinking fast D. Thinking and intelligence

Section B
Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.
“My kids really understand solar and earth-heat energy,” says a second-grade teacher in Saugus, California. “Some of them are building solar collectors for their energy course.” These young scientists are part of City Building Educational Program (CBEP), a particular program for kindergarten through twelfth grade that uses the stages of city planning to teach basic reading, writing and math skills, and more.
The children don't just plan any city. They map and analyze the housing, energy, and transportation requirements of their own district and predict its needs in 100 years. With the aid of an architect who visits the classroom once a week, they invent new ways to meet these needs and build models of their creations. “Designing buildings of the future gives children a lot of freedom,” says the teacher who developed this program. “They are able to use their own rich imagination and inventions without fear of blame, because there are no wrong answers in a future context. In fact, as the class enters the final model-building stage of the program, an elected “official” and “planning group” makes all the design decisions for the model city, and the teacher steps back and becomes an adviser.”
CBEP is a set of activities, games and imitations that teach the basic steps necessary for problem-solving: observing, analyzing, working out possible answers, and judging them based on the children's own standards.
65. The Program is designed to __________.
A. direct kids to build solar collectors
B. train young scientists for city planning
C. develop children's problem-solving abilities
D. train kids to be future architects
66. An architect pays a weekly visit to the classroom to ___________.
A. find out kids' creative ideas B. discuss with the teacher
C. give children lectures D. help kids with their program
67. Who is the designer of the program?
A. An official. B. An architect. C. A teacher. D. A scientist.
68. The children feel free in the program because they _____________.
A. can design future buildings themselves B. have new ideas and rich imagination
C. are given enough time to design models D. need not worry about making mistakes

Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone(臭氧)levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.
72. According to the new findings, taking steps to prevent northern forest fires may _______.
A. result in a warming climate
B. cause the forest fires to occur more frequently
C. lead to a longer fire season
D. protect the forests and the environment there
73. Earlier studies about northern forest fires _________.
A. analyze all aspects of how northern fires influence climate
B. indicate that forest fires will pollute the atmosphere
C. suggest that people should take measures to protect environment
D. suggest that the fires will speed up climate warming
74. The underlined phrase “soak up” in the last paragraph most probably means ________.
A. released B. absorbed C. created D. disturbed
75.From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may __________.
A. warm the climate as the supposition goes
B. allow more snow to reflect more sunlight into space and thus cool the climate
C. destroy large areas of forests and pollute the far-off sea ice
D. help to gain more energy rather than release more energy

Section B
Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.
I am a good mother to three children. I have tried never to let my profession stand in the way of being a good parent.
I no longer consider myself the center of universe. I show up. I listen. I try to laugh. I was a good friend to my husband. I have tried to make marriage vows(誓约)mean what they say. I am a good friend to my friends, and they to me. Without them, there would be nothing to say to you today.
So here’s what I wanted to tell you today: Get a life. A real life, not a desire of the next promotion, the bigger paycheck, the larger house.
Get a life in which you are not alone. Find people you love, and who loves you. And remember that love is not leisure, it is work. Pick up the phone. Send an e-mail. Write a letter. And realize that life is the best thing and that you have no business taking for granted.
It is so easy to waste our lives, our days, our hours, and our minutes. It is so easy to exist instead of to live. I learned to live many years ago. Something really, really bad happened to me, something that changed my life in ways that, if I had my choice, it would never have been changed at all. And what I learned from it is what, today, seems to be the hardest lesson of all.
I learned to love the journey, not the destination. I learned to look at all the good in the world and try to give some of it back because I believed in it, completely and totally. And I tried to do that, in part, by telling others what I had learned.
65. How did the writer form her view of life?
