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, 000 stars, all within 100
light 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 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 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 (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 20
billion 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. |

When Babbage was working at Cambridge, a new idea occurred to him. He wanted to construct a
calculating machine to work out the solutions (解法) to maths problems not only with correctness but
also with a speed beyond the power of any human mind. His machine could solve problems involving
(涉及) long rows of figures in one continuous operation (运算).
In 1822 Babbage exhibited his invention and won a prize from the government. After that, he
immediately started to work on a larger machine designed to solve more difficult problems. Although he
received some money left by his father, the money was not enough to support his design. He wrote to
the government about his plan and was given ￡2500 to start with, a sum worth much more in those days
than it is now.
Babbage continued his work in London for four years. Then his health broke down, and he had to take
a long holiday abroad. When he returned to London in 1828, he was at the end of his resources. Many bills
remained unpaid. His chief assistant and co-workers quarreled with him and left with many expensive tools.
For one year no work was done. During this period, Babbage, whose mind was always active, suddenly
thought of a completely new idea for the machine. He rushed to meet the government officials to explain his
new idea. But this time, they were unwilling to help him. For eight years, they refused to say whether they
wanted the machine or not, and their final answer was "No."
From 1828 to 1839, Babbage held the position of professor at Cambridge very successfully. But his
greatest work was the unfinished calculating machine which stood covered in dust in his house. It was the
beginning of the modern computer. |
|
| 1. The machine Babbage designed would solve difficult maths problems ______. |
A. in one operation with few mistakes
B. in more than one operation without any mistakes
C. in more than one operation with slight mistakes
D. in one operation without any mistakes |
| 2. Babbage failed to continue his research work in 1828 mainly because _______. |
A. he was in poor health
B. he almost ran out of money
C. his co-workers argued with him
D. he spent all his money on his bills |
| 3. Babage explained his new idea to the government officials, expecting that _______. |
A. they would agree to his plan
B. they would pay for his new idea
C. they would support him with money
D. they would exhibit his new design |
| 4. From the passage, we can infer that _______. |
A. Babbage failed to be a famous scientist at Cambridge
B. Babbage always had new ideas but gave them up easily
C. Babbage always needed support from the government officials
D. Babbage was the first designer of the modern computer |

You"re sitting on the train home and the person opposite you yawns (打哈欠). Suddenly, you"re yawning
with him, though you"re not tired.
This phenomenon confused scientists for years until a recent study found that people tend to sympathize
with fellow humans. Supporting this claim was the discovery that those children who were unable to form
normal emotional ties with others did not experience contagions (有感染力的) yawning, which showed that
humans communicate regularly without words.
Hogo Critchley, a neuroscientist, has conducted an experiment recently, which will prove that happiness
and sadness can spread like the common cold. According to Critchley, our mind and body are in constant
exchange about how we"re feeling. "Emotions are closely linked with states of internal (内部的) responses,"
he explained. "There are also more visible changes in our gesture and facial expressions. When we"re in a
group, these signals can spread to another person. For example, there"re the obvious tendency to smile when
smiled at and there are less obvious changes that reflect emotions of surprise, anger or sadness such as a
change in our heart rate and blood pressure."
Hugo Critchley further explained, "Our bodies synchronise and when we like the other Person, we even
copy his behaviour. Next time you chat with a friend, take note of how you"re sitting-it"s pretty likely that
you will be the same. Scientists believe it"s our way of telling each other that you"re parents. Through body
language, humans give each other very subtle (微妙的) but clear signals that show emotions."
So, what lessons can we learn from this? "spend time with happy people-otherwise your health could
suffer," said Critchley. "When we"re sad, our body goes into fight or flight mode. But when we"re happy, our
body works normally and we feel relaxed and positive. So we look bright, our skin glows, we feel healthy and
it affects everyone around us." |
| 1. According to Hugo Critchley, _____. |
A. emotions are as visible as facial expressions
B. we yawn more frequently when we have a cold
C. emotions are connected with states of internal responses
D. the change of blood pressure is not linked with the change of emotions |
| 2. The underlined word "synchronise" in paragraph 4 means "_____". |
|
A. move slowly
B. change rapidly
C. relax temporarily
D. respond accordingly |
| 3. From the passage we can learn _____. |
A. sadness is as contagious as happiness
B. anger is less contagious than friendliness
C. surprise is more contagious than smile
D. surprise is the most contagious among emotions |
| 4. Which of the following statements is true according to the passage? |
A. Emotions have delicate influence on fellow humans.
B. Children like copying the actions of the fellow humans.
C. Scientists are still confused about contagious yawning.
D. People tend to communicate more with body language. |

A good study environment is as important as the studying itself. Here are a few suggestions that will help
you in making a good study environment for yourself. Take care of these, and you will find that you are doing
better by the day.
1. ( )
Pick a suitably quiet place, not necessarily where you can hear a pin drop, but not where you have people
screaming all around you, either. At the same time, if too much quietness makes you feel lonely, then you may
try playing some soft music in the background.
2.( )
Think of all the related materials that you may require, and gather them beforehand. It"s OK if you end up
not using a few of the books. Get a fruit or some snacks that will keep you comfortably full, without being too
heavy on your tummy. (胃)
Lighting is very important.
You must have a reasonable amount of lighting that will let you read properly, without putting stress on
your eyes, or making them burn and water after a while. 3. ( ) And at night, make sure that you have a light
that shines brightly on the book that you are reading.
Know your limits.
Don"t compare yourself with your friend. Seriously, this is not a competition to see who studies more in a
day. You are you, and you are not your friend. 4. ( ) Stop asking your friend constantly how much he has
finished, or telling him how much you have done.
Study smartly instead of studying hard.
5. ( ) Read important points, and highlight important sentences. Use techniques like mind mapping, logical
linking of points, or short forms to remember long lists. This will increase the speed of your studying, and help
you in getting more done in less time. |
A. Select a quiet place.
B. The effect will be the same.
C. He has his limits, and you have yours.
D. Get all your stuff together before you start.
E. Get a nice and comfortable chair for yourself.
F. Try picking a place by the window during the daytime.
G. Reading through the entire text like it"s a novel is pointless. |

Here are a few tips we"ve put together to help you learn English well.
Speak, speak, speak!
Practise speaking as often as you can-even speaking to yourself is good practice. Try recording yourself
whenever you can. Compare your pronunciation with the master version, see how you can do better and have
another try. If you do this several times, you will find that each version is better than the last.
Why not learn with someone else?
It helps if you can learn with someone else. If you can persuade a friend or family member to study with
you, it will make you keep working. Arrange times to meet and set goals for the week, and test each other
regularly.
Don"t get stuck (卡住) by a word you don"t know Practise improvising (即兴的) ways of getting your
meaning across while speaking spontaneously (本能), even if you don"t know the exact words or phrases.
Think of things you might want to say whenever you have spare time. A basic example is the use of tenses.
If you don"t know the past tense but want to talk about yesterday, use the verb in the present tense and use
the word for"yesterday". Use facial expressions, hand movements, anything to get your meaning across.
Language learning is also about intuition (直觉) Guesswork is important in learning a new language. When
listening to recorded material, you aren"t expected to understand everything first time round. If you play the
same piece several times, you will most probably understand something new each time. Learn to make
maximum use of all the clues you can pick up. For example, what do the speakers sound like? Happy? Angry?
Calm? Etc.
Build up your vocabulary A wide vocabulary is the key to successful language learning but don"t try to
learn too much at once. It"s best to study frequently, for short periods of time. Take a maximum of six or
seven items of vocabulary and learn them. Put them into sentences to fix them in your mind, then come back
to them later. Much of the vocabulary in the course is presented by topic. And above all, have fun! |
| 1. Why should one have himself recorded when practicing speaking? |
A. To encourage others to start.
B. To record his own progress.
C. To improve his speaking.
D. To compare himself with others. |
| 2. Which of the following is the most important in learning English? |
A. Speaking.
B. Pleasure. C. Intuition.
D. Vocabulary. |
| 3. It is important in Tip 3 that _____ is helpful when you are learning English. |
A. body language
B. a good memory
C. a good friend
D. a proper dictionary |
| 4. Which of the following seems NOT to be true in learning a language? |
A. Practice makes perfect.
B. A good beginning is half done.
C. Rome is not built in a day.
D. Don"t run before you can walk. |

What would you think if you went back to school on Monday and there were no desks or chairs in your
classroom?
That"s what some fourth-and-fifth-graders at a school in Minnesota discovered earlier this year when they
took part in a research project to see if changing their classrooms would make them more active.
Researchers from the Mayo Clinic were concerned about reports that as many as half of American kids
could be seriously overweight-or obese-by the year 2010. So they set up a different kind of classroom, which
you might see in the future.
Instead of desks, the Elton Hills Elementary students had adjustable work stations where they could stand,
kneel on mats or sit on big exercise balls. Students were given laptops and iPods that allowed them to move
and learn at the same time.
Sensors (传感器) were attached to the kids" legs to calculate how many calories students burned in their
new set-up.
Their typical school day was probably not anything like yours. One group of students downloaded an
audio file (有声文件) of their teacher reading a book; they listened to it while walking for exercise. Another
group took a spelling test by listening to their iPods.
Some students liked the freedom, but others missed the traditional classroom.
"I don"t like standing up," Mariah Matrious said."My legs get tired, and I like sitting down." So, did the
experiment work? Researchers still are studying the data, but early results indicate that the kids did move
around more in the new classroom.
"It showed us that, given the opportunity to move, kids will move," said researcher Lorraine
Lanningham-Foster.
That"s important because studies have shown that even simple movement-climbing stairs instead of taking
an elevator (电梯), for example, or washing dishes by hand instead of loading the dishwasher-can be as
important as formal exercise when it comes to controlling one"s weight. |
| 1. The school in Minnesota carried out the research _____. |
A. to punish the badly performed students
B. to prevent children from being too fat
C. to spare a lot of money for the state
D. to meet the needs of different children |
| 2. The newly designed classrooms are different from the traditional ones EXCEPT that _____. |
A. there were no desks and chairs
B. the students can move and learn at the same time
C. students in different groups are given different tasks
D. teachers don"t necessarily instruct the students |
| 3. According to Lorraine Lanningham-Foster, _____. |
A. the research got some expected results
B. the experiment needs further changes
C. not everyone liked the freedom of this new style
D. The students should be taught without classrooms |
| 4. What would be the best title for the text? |
A. No Desks or Chairs in the Classroom
B. New Classrooms in the Future
C. School Takes a Stand Against Obesity
D. Washing dishes by hand in the Classroom |
