What makes it rain? Rain falls from clouds for the same reason anything falls to Earth. The Earth's gravity pulls it. But every cloud is made of water droplets or ice crystal(冰晶). Why doesn't rain or snow fall constantly from all clouds? The droplets or ice crystals in clouds are extremely small. The effect of gravity on them is slight. Air currents move and lift droplets so that the net downward amount of water is zero, even though the droplets are moving constantly.
It can be seen that droplets and ice crystals behave somewhat like dust in the air in a beam of sunlight. To the casual observer, dust seems to act in a totally random fashion, moving about
without fixed direction. But in fact dust particles（分子） are much larger than water droplets and they finally fall. The average size of a cloud droplet is only 0.0004 inch in diameter（直径）. It is so small that it would take sixteen hours to fall half a mile in perfectly still air, and 
it
doesn't fall out of moving air at all. Only when the droplet grows to a diameter of 0.008 inch or larger can it fall from the cloud. The average raindrop contains a million times as much water as a tiny cloud droplet. The growth of a cloud droplet to a size larger eno
ugh to fall out is the cause of rain and other forms of precipitation. This important growth process is called "coalescence". Ice crystals do NOT immediately fall to Earth because .
| A．they are kept up by air currents |
| B．most of them change into steam |
| C．they combine with other chemicals in the atmosphere |
| D．their electrical charges draw them away from the earth |
The underlined word "random" in line 10 most probably means .
| A．unpredictable | B．strict | C．independent | D．abnormal |
What can be inferred about drops of water larger than 0.008 inch in diameter?
| A．They never occur. |
| B．They are not affected by the force of gravity. |
| C．In moving air they would fall to earth. |
| D．In still air they fall a speed of thirty-two miles per hour. |
How much bigger is the rain drop than a loud droplet?
| A．200 times bigger |
| B．1,000 times bigger |
| C．100,000 times bigger |
| D．1,000,000 times bigger |
Rome had the Forum. London has Speaker' s Corner. Now always-on-the-go New Yorkers have Liz and Bill.
Liz and Bill, two college graduates in their early 2Os, have spent a whole year trying to have thousands of people talk to them in subway stations and on busy street corners. Just talk.
Using a 2-foot-tall sign that says, "Talk to Me," they attract conversationalists, who one evening included a mental patient, and men in business suits.
They don't collect money. They don't push religion (宗教). So what's the point?
"To see what happens," said Liz. "We simply enjoy life with open communication(交流)."
Shortly after the September 11, 2001 attacks, they decided to walk from New York City to Washington, a 270-mile trip. They found they loved talking to people along the way and wanted to continue talking with strangers after their return.
"It started as a crazy idea," Liz said. "We were so curious about all the strangers walking by with their life stories. People will talk to us about anything: their jobs, their clothes, their childhood experiences, anything."
Denise wanted to talk about an exam she was about to take. She had stopped by for the second time in two days, to let the two listeners know how it went.
Marcia had lost her husband to a serious disease. "That was very heavy on my mind,” Marcia said. "To be able to talk about it to total strangers was very good," she explained.
To celebrate a year of talking, the two held a get-together in a city park for all the people they had met over the past year. A few hundred people showed up, as well as some television cameramen and reporters.
They may plan more parties or try to attract more people to join their informal talks. Some publishers have expressed interest in a book, something they say they'll consider.What did Liz and Bill start doing after September 2001?
| A．Chatting with people. |
| B．Setting up street signs. |
| C．Telling stories to strangers. |

| A．They knew Liz and Bill very well. |
| B．They happened to meet the writer of the text. |
| C．They organized the get-together in the city park. |
| D．They are examples of those who talked to Liz and Bill. |
What will Liz and Bill do in the future?
| A．Go in for publishing. | B．Do more television programs. |
| C．Continue what they am doing. | D．Spend more time reading books. |
How do they like the idea of writing a book?

Some people bring out the best in you in a way that you might never have fully realized on your own. My mom was one of those people.
My father died when I was nine months old, making my mom a single mother at the age of eighteen. While I was growing up, we lived a very hard life.
We had little money, but my mom gave me a lot of love. Each night, she sat me on her lap and spoke the words that would change my life, “Kemmons, you are certain to be a great man and you can do anything in life if you work hard enough to get it.”
At fourteen, I was hit by a car and the doctors said I would never walk again. Every day,my mother spoke to me in her gentle,loving voice, telling me that no matter what those doctors said, I would walk again if I want to badly enough. She drove that message so deep into my heart that I finally believed her.A year I returned to school—walking on my own !
When the Great Depression(大萧条)hit, my mom lost her job. Then I left school to support the both of us. At that moment, I was determined never to be poor again.
Over the years, I experienced various levels of business success. But the real turning point occurred on a vacation I took with my wife and five kids in1951. I was dissatisfied with the second-class hotels available for families and was angry that they charged an extra $2 for each child. That was too expensive for the average American family. I told my wife that I was going to open a motel(汽车旅馆)for families that would never charge extra for children. There were plenty of doubters at that time.
Not surprisingly, Mom was one of my strongest supporters. She worked behind the desk and even designed the room style. As in any business,we experienced a lot of challenges. But with my mother’s words deeply rooted in my soul, I never doubted we would succeed.Fifteen years later,we had the largest hotel system in the world—Holiday Inn. In 1979 my company had 1759 inns in more than fifty countries with an income of $1billion a year.
You may not have started out life in the best situations. But if you can find a task in life worth working for and believe in yourself, nothing can stop you.What Kemmons’mom often told him during his childhood was______

As any homemaker who has tried to keep order at the dinner table knows, there is far more to a family meal than food. Sociologist Michael Lewis has been studying 50 families to find out just how much more.
Lewis and his co-workers carried out their study by videotaping(录像) the families while they ate ordinary meals in their own homes. They found that parents with small families talk actively with each other and their children. But as the number of children gets larger, conversation gives way to the parents’ efforts to control the loud noise they make. That can have an important effect on the children. “In general the more question-asking the parents do, the higher the children’s IQ scores,” Lewis says. “And the more children there are, the less question-asking there is.”
The study also provides an explanation for why middle children often seem to have a harder time in life than their siblings(兄弟姐妹). Lewis found that in families with three or four children, dinner conversation is likely to center on the oldest child, who has the most to talk about, and the youngest, who needs the most attention. “Middle children are invisible,” says Lewis. “When you see someone get up from the table and walk around during dinner, chances are it’s the middle child.” There is, however, one thing that stops all conversation and prevents anyone from having attention: “When the TV is on,” Lewis says, “dinner is a non-event.”The writer’s purpose in writing the text is to _________.
| A．show the relationship between parents and children |

TOKYO, Japan (AP) – Japan is very serious about robotics (机器人技术). If the androids are going to fit in, they probably need to learn the Japanese custom of serving tea. Fortunately, researchers at the University of Tokyo are exploring just that. In a show this week, an android（有人特点的）with camera eyes made by Kawada Industries Inc. poured tea from a bottle into a cup. Then another robot on wheels delivered the cup of tea in an experimental room that has sensors(感应器)embedded in the floor and sofa as well as cameras on the ceiling, to simulate（模仿）life with robot technology.
“A human being may be faster, but you’d have to say ‘Thank you,’” said University of Tokyo professor Tomomasa Sato. “That’s the best part about a robot. You don’t have to feel bad about asking it to do things.”
Sato believes Japan, a rapidly aging society where more than a fifth of the population is 65 or older, will lead the world in designing robots to care for the elderly, sick and bedridden（卧床不起的）. Already, monitoring technologies, such as sensors that automatically turn on lights when people enter a room, are becoming widespread in Japan.
The walking, child–size Asimo from Honda Motor Co. greets people at showrooms. NEC Corp. has developed a smaller companion robot on wheels called Papero. A robot available since 2004 can entertain the elderly and others in need of companionship.
Sato says his experimental room is raising awareness about privacy questions that may arise when electronic devices（设备）monitor a person’s movements down to the smallest detail.
On the bright side, the tea – pouring humanoid has been programmed to do the dishes.What is the best title of this passage?
| A．“Thank You” Will Never Be Needed in Japan |
| B．Monitoring Technologies Are Widespread in Japan |
| C．Robot Is Designed to Care for the Elderly. |
| D．Robot technologies are widespread in Japanese daily life. |
The underlined word “embedded” in the first paragraph probably means.
| A．fixed | B．established | C．settled | D．rooted |
According to Professor Sato,.
| A．the robot serves tea much faster than a human being |
| B．the robot does anything like human beings |
| C．tea – serving robot helps to form laziness of the aging society |
| D．tea – serving robot doesn’t need any reward for the service |
Which of the following statements is NOT true?
| A．A robot can imitate people to complete complicated tasks. |
| B．A robot has been programmed to clean the dishes. |
| C．All the problems in the aging society can be solved by robots. |
| D．The number of aging people is increasing rapidly in Japan. |
We can infer from the passage that .
| A．people are afraid of being monitored by robots. |
| B．the technology of robots has been highlighted（强调） in Japan. |
| C．robots can completely take the place of human beings. |
| D．people’s privacy should be strictly protected |
"Beating is a sign of affection, cursing (骂）is a sign of love."
Many may not expect to hear the words of the old Chinese saying in these modern times—with parents wealthier and better educated than they have ever been—but experts say they still ring true.
Today, it seems, Chinese parents are more likely to send their children to pre-college military academies in the United States in the hope that some tough love will pave the way tosuccess.
"Good education doesn't mean letting your child enjoy privileges, especially our boys," said Song Wenming, an entrepreneur(企业家）in Jinhua, East China's Zhejiang province." They should be raised in tough conditions to know what to fight for in the future."
In August, Song sent his 17-year-old son to Valley Forge Military Academy (VFMA) in Pennsylvania. And he is far from alone, even though it takes a lot of money - around $48,000 per year —to send a child to a strict military school.
Statistics shows that an increasing number of Chinese students have been registering with such academies.
A few years ago, there were no Chinese students at Valley Forge. Today, there are 28."All of the Chinese students at Valley Forge came from wealthy families, some of them were spoiled," said Jennifer Myers, director of marketing and communications at the school.
Song's only son, Song Siyu, had a rocky start during his first six weeks at the school. The teenager said he went to the school voluntarily but did not expect it to be as difficult.
Now, three months later, he has perfected the art of taking a bath in 35 seconds, finishing a meal without looking at his food, and making his bed with precision. He can even take criticism, no matter how unreasonable.
"The training is hard but I know it is good for self-development of individuals," said Song Siyu.'The endless training and scolding are just ways to build up our character, they are not personal."
But his enthusiasm is not universal. Ten of the 13 Chinese students who joined the academy this year have transferred to other schools.
But for those who stick with it, there is a reward for all the hard work.From the second paragraph, we can know the old Chinese saying _____.
| A．is out of date in modern times. |
| B．is disagreed by rich parents. |
| C．is still worth trusting. |
| D．is deeply believed by better educated parent. |
The underlined sentence means that _____
| A．Song sent his only son to military school, so he feels lonely. |
| B．Song is the only one who sends his child t to military school. |
| C．There are other people sending their children to military school besides Song. |
| D．The fee of the military school is so high that only Song can afford it. |
Song Siyu got some achievements in the military school except _____.
| A．taking a bath in a short time | B．having his meal with his eyes closed |
| C．taking unreasonable criticism | D．improving his character |
How many Chinese students are there at Valley Forge before this year?
| A．10 | B．13 | C．15 | D．25 |
Which of the following can be inferred from the passage?
A. It's likely that more and more Chinese students will attend VFMA.
B. Most Chinese parents approve of educating their children by beating and cursing nowadays.
C. Song Siyu had no difficulty in adjusting to the life at VFMA.
D. Most Chinese students support the way of education at VFMA.
