For hundreds of years humans have dreamed of finding life on distant planets.Now the hope of discovering real evidence of life has greatly increased.
NASA's Mars detector(探测器),Opportunity,succeeded in finding signs that water once existed on the planet.Opportunity landed on Mars in January.Scientists now believe that the planet could once have supported life.
This discovery was chosen by Science,one of the world's leading magazines,as the most important scientific achievement of 2004 last Friday.
“This little,wheeled,one-armed box went around another planet and has done something no human has ever managed,” according to Science.“It has discovered another place in the universe where life could once have existed.
“Although we still can't say that life could have existed in this environment,it is now certain that there was water on Mars,”said Steve Squyres,one of the scientists working on the Mars mission.The evidence comes from pictures and chemical readings taken by Opportunity.It includes marks on rocks like those caused by following water on Earth and salty chemicals like those found in dried-out sea-beds.Scientists said the new evidence proved beyond doubt that water has existed on Mars.But it is still unknown whether the water was like an ocean or just ice.
While Opportunity has not found any signs of life,the presence of water means life is possible.“In everything we know about life on Earth,there is no example without liquid water,” Squyres said.“So water is important for the search for life on Mars.”
Researchers agree that a future mission(任务) should bring back physical samples(样品).But some scientists worry about the risk that this could introduce dangerous foreign creatures to Earth.“The problem here is how to get the samples back,”Squyres replied.“I think it is our responsibility to limit any risk.”
What proved that water existed on Mars?

A.The physical samples with salty chemicals.
B.The marks on rocks and salty chemicals.
C.Scientific achievements of 2004.
D.Creatures from Mars.

Which of the following is true according to the text?

A.It is now certain that there was water on Mars.
B.The water on Mars was like an ocean.
C.Evidence of life on Mars has been found.
D.Search for life on Mars is a great risk to humans.

How did scientists draw the conclusion that there was water on Mars?

A.The world's leading magazine has announced the fact.
B.Scientists have taken many pictures and chemical readings on the Mars.
C.Astronauts have got some rocks from Mars.
D.Scientists have made a study of the pictures and readings sent back by Mars detector.

It can be inferred that,if the creatures from Mars came to earth,_________.

A.they would be kind to humans
B.they would be cruel to humans
C.they would be a great danger to Earth
D.it would be hard to say whether it would be good news or bad news

In a country that defines itself by ideals, not by shared blood, who should be allowed to come to work and live here? In the wake of the Sept.11 attacks these questions have never seemed more pressing.
On Dec.11, 2001, as part of the effort to increase homeland security, federal and local authorities in 14 states staged “Operation Safe Travel”---raids on airports to arrest employees with false identification.In Salt Lake City there were 69 arrests.But those captures were anything but terrorists, most of them illegal immigrants from Central or South America.Authorities said the undocumented workers’ illegal status made them open to blackmail(讹诈)by terrorists.
Many immigrants in Salt Lake City were angered by the arrests and said they felt as if they were being treated like disposable goods.Mayor Anderson said those feelings were justified to a certain extent.“We’re saying we want you to work in these places, we’re going to look the other way in terms of what our laws are, and then when it’s convenient for us, or when we can try to make a point in terms of national security, especially after Sept.11, then you’re disposable.They are whole families being uprooted for all of the wrong reasons,” Anderson said.
If Sept.11 had never happened, the airport workers would not have been arrested and could have gone on quietly living in America, probably indefinitely.Ana Castro, a manager at a Ben & Jerry’s ice cream shop at the airport had been working 10 years with the same false Social Security card when she was arrested in the December airport raid.Now she and her family are living under the threat of deportation(驱逐出境).Castro’s case is currently waiting to be settled.While she awaits the outcome, the government has granted her permission to work here and she has returned to her job at Ben & Jerry’s.
How did the immigrants in Salt Lake City feel about “Operation Safe Travel”?

A.Guilty B.Offended C.Disappointed D.Discouraged

Undocumented workers became the target of “Operation Safe Travel” because ____.

A.evidence was found that they were potential terrorists
B.most of them worked at airports under threat of terrorists
C.terrorists might take advantage of their illegal status
D.they were reportedly helping hide terrorists around the airport

By saying “…we’re going to look the other way in terms of what our laws are”, Mayor Anderson means “______”.

A.there are other ways of enforcing the law
B.we will examine the laws in a different way
C.we will turn a blind eye to your illegal status
D.the existing laws must not be ignored

Communications technologies are far from equal when it comes to conveying the truth.The first study to compare honesty across a range of communication media has found that people are twice as likely to tell lies in phone conversations as they are in emails.The fact that emails are automatically recorded—and can come back to puzzle you---appears to be the key to the finding.
Jeff Hancock of Cornell University in Ithaca, New York, asked 30 students to keep a communications diary for a week.In it they noted the number of conversations or email exchanges they had lasting more than 10 minutes, and confessed to how many lies they told.Hancock then worked out the number of lies per conversation for each medium.He found that lies made up 14 per cent of emails, 21 percent of instant messages, 27 per cent of face-to-face interactions and an astonishing 37 percent of phone calls.
His results to be presented at the conference on human-computer interaction in Vienna, Austria, in April, have surprised psychologists.Some expected emailers to be the biggest liars, reasoning that because deception makes people uncomfortable, the indirect contact of emailing would make it easier to lie.Others expected people to lie more in face-to-face exchanges because we are most practiced at that form of communication.
But Hancock says it is also crucial whether a conversation is being recorded and could be reread, and whether it occurs in real time.People appear to be afraid to lie when they know the communication could later be used to hold them to account, he says.This is why fewer lies appear in email than on the phone.
People are also more likely to lie in real time---in an instant message or phone call, say---than if they have time to think of a response, says Hancock.He found many lies are spontaneous(脱口而出) responses to an unexpected demand, such as: “Do you like my dress?”
Hancock hopes his research will help companies work out the best ways for their employees to communicate.For instance, the phone might be the best medium for sales where employees are encouraged to stretch the truth.But, given his result, work assessment where honesty is a priority, might be best done using email.
Hancock’s study focuses on _______.

A.the consequences of lying in various communications media
B.the success of communications technologies in conveying ideas
C.people are less likely to lie in instant messages
D.people’s honesty levels across a range of communications media

A.They are afraid of leaving behind traces of their lies
B.They believe that honesty is the best policy
C.They tend to be relaxed wh en using those media
D.They are most practised at those forms of communication

It can be inferred from the passage that ________.

A.honesty should be encouraged in interpersonal communications
B.suitable media should be chosen for different communication purposes

D.email is now the dominant medium of communication within a company

Greeks play a special game at Easter and it’s good fun! The rules of the game are as follows: 1.Everyone picks out a hard-boiled Waster Egg.2.Each player finds a partner.One person will be a “holder”, and the other will be a “tapper”.Holders should hold the egg with either the pointy end or the round end facing up.Tappers should hold the egg with that same end facing down.Tapping must be done pointy-end-to-pointy-end or round-end-to-round-end.3.With one good tap, the tapper tries to crack the holder’s egg.One player will end up with a cracked egg.4.Each player finds another partner and repeats steps 2 and 3.(After one end of the egg is cracked, players may continue to play using the uncracked end).5.A player loses when both ends of his egg have been cracked.The winner is the person who still has an uncracked egg.6.Enjoy eating the eggs!
Dye your Easter eggs.With an adult’s help, dye hard-boiled eggs red using food coloring or egg dye.For a nice sheen, use a paper towel to rub some oil on each egg.But don’t use too much oil---you wouldn’t want your egg to slide out of your hand when you play the egg-cracking game!
Why dye eggs red? Eggs represent new life and the red dye symbolizes the pain and suffering in the past.

With the rapid social development, the Internet now provides social networks that include online movies and videos.The major television networks have much less control over your mind and their broadcasts for entertainment and, more importantly, advertising.It has long been known that television’s audience will spend more time on the Internet than watching TV.People have found another means of entertainment by going to websites which seem to satisfy their specific interests more completely.This isn’t very good news for the television networks.
The influence of people using DVRs (Digital Video Recorder) also has led to fewer and fewer viewers watching television commercials.Market research indicates the effectiveness of TV ads is getting weaker as a result.Many DVR owners are fast forwarding and skipping television commercials.With viewers now spending an average of four times longer on the Internet and more viewers avoiding commercials, this trend isn’t good for television’s advertising revenues(收益).
Major TV advertisers know full well that their advertising dollars on TV aren’t as an effective investment as they once were.The major players in advertising have been moving towards the Internet as a serious alternative means of advertising.
For thousands of people involved in Internet marketing, it’s history-making to share the revenue that previously all went to major television networks.There’s already a group of Internet marketers being paid a larger amount of advertising revenue.These are everyday people that work usually from home on their own.Advertisers can direct their advertising to websites where viewer types are more likely to be interested in their product or service.
The development of the Internet and its role and change in our lives cannot be compared to any other form of media created throughout the history of mankind.
People are going to websites for entertainment because _______.

A.they’d like to follow the last trend
B.there are fewer commercials
C.there are more movies and videos
D.they can choose what meets their particular needs

“To be or not to be”.Outside the Bible, these six words are the most famous in all the literature of the world.They were spoken by Hamlet when he was thinking aloud, and they are the most famous words in Shakespeare because Hamlet was speaking not only for himself but for every thinking man and woman.To be or not to be----to live or not to live, to live richly and abundantly and eagerly, or to live dully and meanly and scarcely.A philosopher(哲学家) once wanted to know whether he was alive or not, which is a good question for everyone to put to himself occasionally.He answered it by saying, “I think, therefore I am.”
But the best definition of existence I ever saw was one written by another philosopher who said, “To be is to be in relations.” If this is true, then the more relations a living thing has, the more it is alive.To live abundantly means simply to increase the range and intensity (强度)of our relations.Unfortunately, we are so constituted (自作决定的)that we get to love our routine.But other than our regular occupation, how much are we alive? If you are interested only in your regular occupation, you are alive only to that extent.So far as other things are concerned----poetry and prose, music, pictures, sports unselfish friendships, politics, international affairs----you are dead.
On the contrary, it is true that every time you acquire a new interest----even more, a new accomplishment----you increase your power of life.No one who is deeply interested in different kinds of subjects can remain unhappy.The real pessimist is the person who has lost interest.
Bacon said that a man dies as often as he loses a friend.But we gain new life by contacts with new friends, and new ideas and thoughts, too.Where your thoughts are, there will be your life also.If your thoughts are limited only to your business, only to your physical welfare, only to your narrow circle of the town in which you live, then you live in a narrow restricted (有限的) life.But if you are interested in the characters of a good novel, then you are living with those highly interested people; if you listen intently to fine music, you are always away from immediate surroundings and living in a world of passion and imagination.
To be or not to be ---- to live intensely and richly, or merely to exist, that depends on ourselves.Let us widen and intensify our relations.While we live, let us live.
What does the author mainly want to do by this passage?

A.Argue against an idea. B.Put forward an idea.
C.Introduce some famous sayings. D.Explain some famous sayings.

What does the underlined word “pessimist” most probably mean?

A.Somebody who always expects the worst to happen.
B.Somebody who is always interested in making new friends.
C.Somebody who always lives in a world of passion and imagination.
D.Somebody who likes to live a rich and abundant life.

Which of the following behaviors is most probably NOT encouraged by the author?

A.Thinking more than your own business.
B.Caring only about your physical welfare.
C.Reading good novels.
D.Listening to fine music.

What is the main idea of the passage?

A.To be or not to be, that is a question. B.I think, therefore I am.
C.To be is to be in relations. D.A man dies as often as he loses a friend.
