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 answer such messages.
Scientists are using powerful radio telescopes to listen to signals from about 1, 000 stars, all within
100 light years of the 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 that stands out from the background noise.
Of the 200 billion stars in the Milky Way galaxy(银河星系), scientists find that 5% are like our sun.
Perhaps half of them have a planet like the earth. Such a planet would be a reasonable distance from the
star for temperatures to be right for the evolution(进化) of life. Based on the inhabitable(适于居住的)
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. If we hope to find intelligent life, these scientists believe that we have to keep
looking.

would admit that their spoken English is poor.Whenever I speak to Chinese students they always
say,"My spoken English is poor."However,their spoken English does not have to remain "poor".
I would like to suggest that there may be some reasons for their problems with spoken English.
First,they fail to find suitable words to express themselves due to a limited vocabulary.
Obviously the better ?answer? is to expand their vocabulary.However,you can speak with a
limited vocabulary,if your attitude is positive.Others will follow you as long as you use the words
that you know.
Second,they are afraid of making mistakes.Sometimes they make mistakes when they are
speaking because they are shy and nervous.Yet students should remember that their goal should
be FLUENTLY NOT ACCURACY.Your aim in writing is to be accurate following therules for
grammar and using the rules to get your message across,to talk to someone in English,as quickly
and well as you can,even though sometimes you may use a wrong word or tense,but it doesn"t
matter because the person you are speaking to will understand you and make allowances for any
mistakes he hears.
The third reason is that not enough attention is paid to listening.You have one mouth but two
ears! All that hearing is necessary for you to start speaking.
Fourth,most Chinese students are reactive rather than proactive language learners.Instead of
actively seeking out opportunities to improve their spoken English they passively wait for speaking
opportunities to come to them and wonder why their English always remains poor.If you have
this proactive outlook,then,you will see English opportunities wherever you go.
If you do not use your English beyond the classroom you will forget that English you know.
Remember:USE IT OR LOSE IT! You can learn how to speak English better by speaking
English more.
Title:Problems with spoken English
generally viewed personal growth as an external(外在的)result or a product that can easily be identified
and measured. The worker who gets a rise, the student whose grades improve, the foreigner who learns
a new language-all these examples of people who have measurable results to show for their efforts.
By contrast(对照), the process of personal growth is much more difficult to determine, since it is a
journey and not the specific signposts or landmarks along the way. The process is not the road itself, but
the attitudes, feelings people have, and their caution or courage, as they meet with new experiences and
unexpected difficulties. In this process, the journey never really ends;there are always new ways to
experience the world, new ideas to try, new challenges to accept.
In order to grow, to travel new roads, people need to have a willingness to take risks, to face the
unknown, and to accept the possibility that they may "fail" at first. How we see ourselves as we try a
new way of being is necessary for our ability togrow. Do we see ourselves as quick and curious? If so,
we tend to take more chances and be more open to unfamiliar experiences. Do we think we"re shy and
indecisive? Then our sense of fear can cause us to hesitate, to move slowly, and we think we are slow to
adapt?(适应)change or that we"re not smart enough to deal with a new challenge. Then we are likely to
take a more passive role or not try at all.
These feelings of insecurity(不安全)and self?doubt are both unavoidable and necessary if we are to
change and grow. If we protect ourselves too much, then we stop growing. We become trapped inside a
shell of our own making.
possessed a slightly above average language ability.It wouldn"t have to be a big talent,just enough so that
she might gain some sense of distinction.Then you would want her to meet,say,a novelist,who
coincidentally shared some similar qualities.Maybe the writer was from the same town,had the same family background,or,shared the same birthday.
This contact would give the girl a vision of her future self.It would give her some idea of a fascinating
circle she might someday join.It would also help if one of her parents died when she was 12,giving her a
strong sense of insecurity and fuelling a desperate need for success.Armed with this ambition,she would
read novels and life stories of writers without end.This would give her a primary knowledge of her field.
She"d be able to see new writing in deeper ways and quickly understand its inner workings.
Then she would practice writing.Her practice would be slow,painstaking and error focused.By
practicing in this way,she delays the automatizing process.Her mind wants to turn conscious,newly learned skills into unconscious,automatically performed skills.By practicing slowly,by breaking skills down into tiny parts and repeating,she forces the brain to internalize a better pattern of performance.Then she would find an adviser who would provide a constant stream of feedback,viewing her performance from the outside,
correcting the smallest errors,pushing her to take on tougher challenges.By now she is redoing
problems-how do I get characters into a room-dozens and dozens of times.She is establishing habits of
thought she can call upon in order to understand or solve future problems.
The primary quality our young writer possesses is not some mysterious genius.It"s the ability to develop a purposeful,laborious and boring practice routine.The latest research takes some of the magic out of great achievement.But it underlines a fact that is often neglected.Public discussion is affected by genetics and
what we"re "hard-wired" to do.And it"s true that genes play a role in our capabilities.But the brain is also
very plastic.We construct ourselves through behaviour.
B. the relationship between genius and success
C. the decisive factor in making a genius
D. the way of gaining some sense of distinction
B. join a fascinating circle of writers someday
C. share with a novelist her likes and dislikes
D. learn from the living examples to establish a sense of security
B. her writing turns into an automatic pattern of performance
C. she acquires the magic of some great achievements
D. she comes to realize she is "hard-wired" to write
B. A responsible adviser is more important than the knowledge of writing.
C. As to the growth of a genius,IQ doesn"t matter,but just his/her efforts.
D. What really matters is what you do rather than who you are.
Chinese parents are being urged to pay more attention to their children"s nutrition, after a study
revealed that unscientific ways of feeding babies and a lack of trace elements are the two biggest threats
to youngsters"health. Experts drew these conclusions from a two year study into the nutrition and health
situation of children under six in ten cities including Beijing, Shanghai and Guangzhou.
Started in 2003 by the China National Children"s Center, the survey includes 8043 children, equally
divided between the sexes. It shows 37 percent of surveyed children have baby food earlier than the
recommended age of four to six months old, with another 35percent taking it later, which in return brings
about a nutrition difference as these children grow up. "Our children above four to six months old fall
behind foreign children in terms of their physical well?being," said Zhao Shunyi, head of the center. She
called on Chinese parents to pay more attention to their children"s nutrition after they stop breast feeding
at six months old.
Trace elements
The survey also shows more than half of the children above six months old are deficient in five trace
elements which are crucial to their physical development-magnesium, copper, calcium, iron and zinc.
"Lack of zinc will lead to low level of intelligence," said Dou Xiaowei, vice director of the National Center
for Child Nutrition Quality Supervision and Testing. "Parents had better choose baby food with plentiful
trace elements, especially calcium, iron and zinc."
Zhao said, "The center is urging the government to strengthen child food production management by
revising related laws. Child food producers should be advised to market products with rich trace
elements."
warn doodling students, sure that they must be daydreaming.
However, according to a recent study, doodling while listening to a boring lecture helps concentrate
(集中)the attention:
Andrade, a psychology professor in England asked participants to listen to a boring lecture. Half the
participants were told to color in squares and circles freely on a piece of paper while listening to the
lecture. The other half weren"t given a task. After it was over, the participants were asked to retell the
lecture.
Those given the doodling task (color in squares and circles) remembered 29 percent more information
than the non-doodlers.Andrade said.
"If someone is doing a boring task, like listening to a dull conversation, they may start daydream,"
said Professor Andrade.
"Daydreaming distracts(使分心)them from the task, resulting in poorer performance. A simple task,
like doodling, can stop them from daydreaming without affecting their performance at the task," he said.
So the next time you"re doodling during a class, and you hear "pay attention", you can tell the teacher
with confidence that you"ve been paying attention to every word.
