19．

Uncivilized behavior by passengers unacceptable
For the first time，airline passengers have been blacklisted for uncivilized behavior．Their names will remain on the blacklist for one or two years，according to an announcement by the China Air Transport Association on Saturday．The blacklisting means they will not be able to travel by air until their names are removed from the list．
Blacklisting passengers who disobey the rules for travelling by air and so place their own interests before everything else，including safety，has long been overdue （迟到的，延迟的）．
There have been frequent reports of passengers making a scene when their flight was delayed or when they believed that they were not treated as they should be on a flight．
Yet it is natural for some flights to be delayed because of reasons such as bad weather or mechanical problems that need to be solved．However，some passengers seem to take it for granted that their flight must take off at the time stated on their ticket，and they even assume that the members of the cabin crew are simply there to do their bidding（吩咐）．
They forget that they should behave themselves in the first place and that respect is reciprocal （互相给与的）．There is no reason for them to be respected when they do not show enough respect for others．
Observing  rules can never be over-emphasized when it comes to flight safety．No one has the right to disregard the rules for any reason．Of course，airlines should provide quality services to meet the needs of passengers．Yet，even if passengers are not satisfied with the service provided，there is still no reason for them to flout the rules that are designed for the safety of all．
The blacklisting of these three passengers should serve for others to know they have to toe the line （顺从集体）．

21．Which of the following statements is TRUE？A
A．Never before have airline passengers been blacklisted．
B．At no time should flights be delayed，whatever the reasons．
C．Members of the cabin crew should be at the passengers'service at any moment．
D．If an airline passenger is blacklisted，he or she will never be allowed to travel by air．

6．For more than twenty years scientists have been searching for signs of life on other planets．Most of these searches have been done over the radio．The hope is that someone in outer space may be trying to get in touch with us．Scientists also have sent radio and television messages on spaceships traveling through space，on the chance that someone may be receptive to such messages．
Scientists are using powerful radio telescopes to listen to signals from about 1，000stars，all within 100light years of earth．In addition，they will scan the entire sky to"listen"for radio messages from more distant stars．Using a computer，they will be able to monitor more than eight channels at one time．Scientists are looking for any signal they stands out from the background noise．
Of the 200billion stars in the Milky Way galaxy，scientists find that five percent are like our sun．Perhaps half of them have a planet like earth．Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution of life．Based on the inhabitable（that can be lived in）planets in our galaxy，most scientists agree that chances are likely that one or more of these planets support some life．
However，many scientists wonder whether intelligent life exists on other planets．Some believe that twenty years of searching without any intelligible messages shows that no one is out there．They say that the evolution of intelligence comparable to ours is unlikely．
Other scientists believe that our search hasn't been long enough to rule out the possibility that intelligent life exists in our galaxy．Although our sun family is only about five billion years old，our galaxy is about 20billion years old．In that time，some scientists think it is likely that civilization much more advanced than ours have developed．Perhaps these civilizations send us no signals； perhaps we have not recognized the signals they have sent us．If we hope to find intelligent life，these scientists believe that we have to keep looking．
28．According to the passage，how many planets in our galaxy might be inhabitable？A
A.5billion．　　　　　　　　　　 B.10billion． C.15billion．D.200billion
29．The first paragraph in this passage is mainly aboutA．
A．how scientists are looking for signs of life on other planets
B．why scientists are looking for signs of life on other planets
C．where scientists are looking for signs of life on other planets
D．when scientists are looking for signs of life on other planets
30．The underlined word"monitor"in the passage means"C"．
A．find　　　　　　　　　　　　　B．imitate
C．check　　　　　　　　　　　　 D．form
31．Which of these statements is true based on the information in the passage？C
A．The earth is one of the oldest planets in our galaxy．
B．Most scientists believe that there is intelligent life on other planets．
C．Scientists are trying different ways to find signs of life on other planets．
D．Scientists don't believe that there might be life on other planets．

20．Are you a team player？
We hear a lot about team building these days．Team-building gurus are hired by some corporations to lecture us on how to work more effectively with each other．And they organize awaydays（息工日）-a time employees spend together away from their usual workplace．
Here in the UK，employees can take part in activities such as Zombie boot camps where military instructors train you how to fight walking'dead people'．For the brainier office workers amongst us there are crime investigations modelled on popular TV dramas like Sherlock Holmes and CSI．
Stressed-out city workers might have ukulele lessons made available to them．Why is that a good team-building exercise？Ukulele teacher Lorraine Bow says："The fact that they can play a musical instrument within an hour is quite a fulfilling thing，really．It's not competitive-it's quite easy to do and a bit less intimidating than a guitar…"
Actually，a horse might be a bit more intimidating than an instrument．The animals are used by a company in Abu Dhabi which teaches leadership through horse training．Basically，you have to go in a yard with a horse and persuade it that you're the boss by using body language．
Kelly Eide，co-founder of True Leadership，says："The horses don't care if your hair is purple，if you're a man or a woman，if you're old or young…It transcends all of those cultural boundaries-age，gender，religion，tradition etc．-so that's a perfect fit．And in an organization where you really need groups of people to gel，who come from backgrounds which have no common norms，you can teach that most efficiently with a horse．"
And the horse feels instinctively whether or not you are a natural leader．So if after you've done a good presentation your boss offers you a carrot，you'll know where he might have learnt it from．
24．What are awaydays for？B
A．To gather employees to join a meeting on how to work more effectively with each other．
