The search for life in the universe took a step forward last month with the opening of the Allen Telescope Array(艾倫望遠(yuǎn)鏡陣列) in Hat Creek, California. The telescopes were partly made possible by a gift of twenty-five million dollars from Paul Allen. The total cost of the project is already fifty million dollars.
At present, there are 42 radio telescopes working at the Hat Creek observatory. The signals they receive are combined to create what is equal to a single, very large telescope. The telescope will be used to observe objects like exploding stars, black holes and other objects that are predicted but have not yet been observed. Seth Shostak of the SETI Institute says this is the first telescope whose main purpose is to search for signals from intelligent life in space. The SETI Institute is based in Mountain View, California. The organization supports the search for other life forms in the universe.
What makes the Allen Telescope Array unusual is that it can collect and study information from a wide area of the sky. In addition, the 42 telescopes can study information about several projects at the same time. That means studies of large areas of the sky can be made faster than ever before.
Some officials think the Allen Telescope Array will be completed in three more years. 350 individual radio telescopes are planned. The new abilities of the Allen Telescope Array will make searching for stars similar to the sun much faster.
An earlier search by SETI, Project Phoenix, studied about 800 stars to a distance of 240 light years. The project ended in 2004. With the Allen Telescope Array, astronomers hope to gather thousands of times more information in the search for life beyond our planet.

More than 200 scientists have completed a two­year study to identify the most natural and undeveloped areas on Earth. Their findings are reported in a new book called Wilderness:Earth’s Last Wild Places. The book describes 37 wilderness areas around the world. Each has an area greater than 10,000 square kilometers. The study considered only areas where at least 70% of all plants are native.
North and South America are home to the largest number of wilderness areas. There are 16 such areas, from southern Argentina to Alaska and northern Canada. Africa has 8 wilderness areas, including the thick forests and the grasslands. Australia and New Guinea (幾內(nèi)亞) share 6 areas. Europe has 3 areas and Asia has 2.The Arabian Desert and Antarctica also are considered wilderness areas.
The largest wilderness area is the Boreal Forest (北方森林).It extends for 16­million square kilometers south of the Arctic Circle. The Boreal Forest extends across Alaska, Canada, northern Europe and Russia. The smallest of the 37 wilderness areas is the Sundarbans. It is the world’s largest tidal mangrove forest (紅樹林).It covers 10,000 square kilometers of land at the mouth of the Ganges River in India and Bangladesh (孟加拉國).
The study found that wilderness areas cover about 46% of the Earth’s land surface. However, they are home to less than 2.5% of the world’s population. Nineteen of the wilderness areas have only about one person for each square kilometer. Native people usually live in these areas.
Wilderness areas help to influence the world’s weather systems and rainfall. They are also home to many plants and animals. Population growth and the spread of agriculture and mining operations threaten wilderness areas. But just 7% of all such areas have some form of official protection.
小題1:What does the author think of the wilderness areas around the world in the book?
A.Unwanted.B.Long-lasting.C.ValuableD.Perfect.
小題2:The writer describes the wilderness areas to show that they ________.
A.a(chǎn)re worth the public supportB.can attract readers’ attention

Boys' schools are the perfect place to teach young men to express their emotions and involve them in activities such as art, dance and music.
Far from the traditional image of a culture of aggressive masculinity (陽剛), the absence of girls gives boys the chance to develop without pressure to obey a stereotype(陳規(guī)舊俗),a US study says.
Boys at single-sex schools were said to be more likely to get involved in cultural and artistic activities that helped develop their emotional expressiveness, rather than feeling they had to obey the "boy code" of hiding their emotions to be a "real man".
The findings of the study go against received wisdom that boys do better when taught alongside girls.
Tony Little, headmaster of Eton, warned that boys were being failed by the British education system because it had become too focused on girls. He criticized teachers for failing to recognize that boys are actually more emotional than girls.
The research argued that boys often perform badly in mixed schools because they become discouraged when their female peers do better earlier in speaking and reading skills.
But in single-sex schools teachers can tailor lessons to boys' learning style, letting them move around the classroom and getting them to compete in teams to prevent boredom, wrote the study's author, Abigail James, of the University of Virginia.
Teachers could encourage boys to enjoy reading and writing with "boy-focused" approaches such as themes and characters that appeal to them. Because boys generally have more acute vision learn best through touch, and are physically more active, they need to be given "hands-on" lessons where they are allowed to walk around. "Boys in mixed schools view classical music as feminine (女性的) and prefer the modern type in which violence and sexism are major themes, "James wrote.
Single-sex education also made it less likely that boys would feel they had to obey a stereotype that men should be "masterful and in charge" in relationships. "In mixed schools boys feel forced to act like men before they understand themselves well enough to know what that means," the study reported.
小題1:The author believes that a single-sex school would ______.
A.force boys to hide their emotions to be "real men"
B.encourage boys to express their emotions more freely
C.help to cultivate masculine aggressiveness in boys
D.naturally reinforce in boys the traditional image of a man
小題2:It is commonly believed that in a mixed school boys ______.
A.perform relatively betterB.grow up more healthily
C.behave more responsiblyD.receive a better education
小題3:What does Tony Little say about the British education system?
A.It fails more boys than girls academically.
B.It focuses more on mixed school education.
C.It fails to give boys the attention they need.
D.It places more pressure on boys than on girls.
小題4:According to Abigail James, one of the advantages of single-sex schools is ______.
A.teaching can be tailored to suit the characteristics of boys
B.boys can focus on their lessons without being distracted
C.boys can choose to learn whatever they are interested in
D.teaching can be designed to promote boys' team spirit
小題5:Which of the following is characteristic of boys according to Abigail James' report?
A.They enjoy being in charge. B.They obey stereotypes.
C.They are violent and sexist.D.They have sharper vision.

How do apology languages work? Have you ever tried to apologize, only to be refused? It may be that you were offering a partial apology in a “l(fā)anguage”, that was foreign to your listener. The five languages of apology include:
Apology Language 1: “I am sorry.”
List the hurtful effects of your action. Not “I am sorry if …”, but “I am sorry that…”. You might ask if they want to add any points that you have not recognized.
Apology Language 2:“I was wrong.”
Name your mistake and accept fault. Note that it is easier to say “You are right” than “ I am wrong”, but the latter carries more weight.
Apology Language 3: “What can I do to make it right?”
How are you now? How shall I make amends(彌補(bǔ)) to you? How can I restore your confidence that I love you— even though I was so hurtful to you?
Apology Language 4: “I’ll try not to do that again.”
Engage in problem-solving. Don’t make excuses for yourself such as, “Well, my day was just so…” Instead, offer what you will change to prevent yourself from putting them in the same bad situation again.
Apology Language 5: “Will you please forgive me?”
Be patient in seeking forgiveness. They may need some time or greater clarification(澄清) of your input from Apology Languages 1-4.
Finally, your apology may not be accepted, but at least you know that you have been faithful in offering a sincere olive branch(橄欖枝) of peace.
小題1:The passage mainly talks about___________
A.5 tips for apologies that workB.5 ways of refusing apologies
C.the function of apology languagesD.the importance of apology languages
小題2:According to Paragraph 1, your apology may be refused mainly because________
A.your listeners can’t understand your dialect.
B.your listeners can’t hear what you said clearly.
C.your apology is not sincere.
D.your apology is not expressed well enough.
小題3:When offering an apology, which of the following does the author prefer?
A.“You are right”B.“I am sorry if …”
C.“I was wrong.”D.“Well, my day was just so…”
小題4:In the last paragraph, the author tells us even if your apology may not be accepted, at least ___________.
A.It’s your fault any moreB.your mind will be at peace
C.your friend will make peace with you.D.your apology is true to your heart

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate, you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo(竹子) . Other animals eat only one type of food even when given the choice. A kind of white butterfly(蝴蝶) will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied(多樣化) diet . The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.
小題1:We can infer from the text that humans and animals _________.
A.depend on one sense in choosing food
B.a(chǎn)re not satisfied with their food
C.choose food in similar ways
D.eat entirely different food
小題2:Which of the following eats only one type of food?
A.The white butterfly.B.The small bird.
C.The bear. D.The fox.
小題3:Certain animals change their choice of food when ___________.
A.the season changes
B.the food color changes
C.they move to different places
D.they are attracted by different smells

in order to know a foreign language thoroughly(完全地), four things are necessary. Firstly, we must understand the language when we hear it spoken. secondly, we must be able to speak it ourselves, with confidence(自信) and without hesitation(猶豫). Thirdly, we must do much reading. Finally, we must be able to write it. We must be able to make sentences that are correct in grammar.
There are no shortcuts to succeed in language learning. A good memory is a great help, but it is not enough only to memorize the rules from a grammar book. it is not much learning by heart long lists ( 一覽表 ) of words and their meanings, studying the dictionary and so on. We must learn by using the language. If we are pleased with a few rules we have memorized, we are not really learning the language. We must "learn through use". Practice is important. We must practice speaking and writing the language whenever we can.
小題1: the most import things to learn a foreign language are
A.understanding and speaking
