Wouldn't it be great if you could just look up at the sky and read the weather forecast right away?
Well, you CAN. The forecast is written in clouds. If you can read that writing, you can tell something about the atmosphere. With some practice, you can become a pretty good weather forecaster. Who knows, you might even do as well as meteorologists (气象学家).
Meteorologists use much more information than just the appearance of the clouds to make their forecast. They collect data from all over the world. Then they put it into powerful, high-speed computers.
This does give meteorologists an advantage, because they can track weather patterns as they move from west to east across the country.
But you have an advantage, too. You have your brains. You can look at the sky and get your data directly. A meteorologist uses a computer forecast that’s several hours old to make a local forecast.
What are you seeing when you look at a cloud? “A picture of what moisture (水气) is doing in the atmosphere,”says meteorologist Peter Leavit. There’s moisture throughout the atmosphere. Most of the time you don't see it, because it's in the form of an invisible gas called water vapor.
Sometimes, the temperature of the air gets cold enough to cause the water vapor to change to liquid water. That’s called condensation, and we see it happen all the time, for example, when humid air from the shower hits the cold glass of a mirror. When enough water vapor condenses, droplets form in the air. These droplets scatter light. A cloud is seen.
Watching clouds over a day or two tells you a lot more than a single cloud about the weather to come. Changes in clouds show changes in the atmosphere.
You should begin to notice patterns. Certain clouds, fol1owing each other in order, can signal an approaching storm. But don’t take our word for it; see for yourself.

Because of the stress and strains of modern life folks today would rather watch television than get together with neighbors. Their behavior doesn't mirror TV soaps like Coronation Street and East Enders.
The Street's Ashley Peacock and Toyah Battersby know all their neighbors. But the Royal Mail survey shows that real-life under35s wouldn't dream of popping next door for a chat or to borrow a cup of sugar.
Three out of ten say they wouldn't know their neighbors if they saw them in the street. The same proportion would only offer to help neighbors if absolutely necessary, while thirty-onepercent don't want to get to know them better. Twenty-six percent rarely or never speak to the person next door. Thirty-five percent only talk to neighbors occasionally, and six percent actively dislike them. The older generation are still sociable, with seventy percent of over55s taking time to chat to people next door. The report says: “In the past, the British tradition of village green gossip（闲聊）between neighbors was celebrated worldwide. But there's been a clear shift away from local links by the young generation.” Londoners are least likely to be neighbors, with a third rarely or never chatting over the garden fence. People in the Midlands—where 65 percent often speak to their neighbors are most friendly.
Sociologist Jane Blakeman said: “People are working longer hours than ever before, and are traveling further to work. It leaves them far less time at home.”Almost a third of young people_______.
| A．know their neighbours quite well |
| B．have no idea who lives next door to them |
| C．talk to their neighbours when they want to borrow something |
| D．spend time chatting with neighbours like their parents |
It can be inferred that Ashley Peacock and Toyah Battersby are both_______.
| A．important roles in a popular TV series |
| B．famous stars in TV programmes |
| C．old soap operas |
| D．members of royal family |
Gossip among neighbours is still common among_______.
| A．people under35s | B．people between 35 and 55 |
| C．people over55s | D．people of different ages |
There is a difference between London and the rest of Britain mainly in that non-Londoners
_______.
| A．would help their neighbours only when necessary |
| B．are less likely to have good relations with their neighbours |
| C．wouldn't travel far and find more time to chat with neighbours |
| D．are more likely to keep up the old British tradition of having a chat over garden fence |
Dear Flowermouse,
Thank you for your comments on how Americans and Chinese view each other. This is an important subject. Modern technology has given many nations the chance of destroying other nations. This is a cruel picture but it is a realistic one. It means that every nation should make sure that these weapons of great destruction are never used. This requires greater acceptance of differences among people and nations in all parts of the planet.
Your letter asks specially about Chinese-American relationships but I want to let you know my feelings on a global scale. Because China and America are the most powerful nations and I believe they have a special responsibility for promoting better understanding and for leading the way toward peaceful solutions to the world's problems.
You ask how Chinese and American people view each other. This is an important question. Because I know so little about China that I am not able to judge how Chinese view Americans. I am sure that the view differs according to individual experiences that persons might have. And it is not easy to describe America to foreigners. America is a vast mass of people and cultures. These people came from all parts of the world, from Asia, Africa, Latin America, Europe and Australia. Each brought a different culture and a different set of values within a single nation.
I believe that the vast majority of Americans like the vast majority of Chinese want peace and friendship between our two nations. Both China and America have suffered through generations from war and violence in our history. And I believe that it is the special responsibility of all Chinese and all Americans to impress this need for mutual understanding on our neighbors in other.
So my friend, this is my response. Please know that I write to you as a private person living in America. I do feel strongly that people everywhere have more in common than they have in differences. We all share the same basic needs for existence and we all depend upon the same need for the survival of this beautiful planet earth. Maybe we can begin to encourage better communication and better understanding through my columns. I hope so.From the passage we can know that Flowermouse_______.
| A．loves Americans |
| B．has read about the writer's articles |
| C．is an American |
| D．knows little about Americans |
It is likely that the writer_______.
| A．disagrees with Flowermouse |
| B．thinks it possible for nations to be destroyed due to modern technology |
| C．thinks American government share the same opinions with its people |
| D．believes the weapons of great destruction are never used |
The letter that Flowermouse wrote to the writer, maybe have referred to .
| A．American culture |
| B．American society |
| C．Chinese-American relationships |
| D．Chinese society |
The writer's purpose to write the passage is to_______.
| A．introduce Americans to us |
| B．make friends with Flowermouse |
| C．speak for the government of America |
| D．call on nations to understand each other |
A peer is a person who is about the same age as you. Peers affect your life, whether you know it or not, just by spending time with you.
Peers can have a good effect on each other. Maybe another student in your science class taught you an easy way to remember the planets in solar system. Maybe you got others excited about your new favorite book, and now everyone's reading it.
However, sometimes peers affect each other in another way. For example, one kid in school might try to get another to cut class with him, your soccer friend might try to persuade you to be mean to another player and never pass him the ball, or a kid in the neighborhood might want you to shoplift with him.
Some kids give in to peer pressure because they want to be liked, to fit in, or because they worry that other kids may make fun of them if they don't go along with the group.Others may go along because they are curious to try something new that others are doing. The idea that “everyone's doing it ” may influence some kids to leave their better judgments, or their common senses behind.
Peer pressure can be extremely strong and hard to get rid of. Experiments have shown how peer pressure can influence someone to change mind from what she knows for sure is a correct answer to the incorrect answer—just because everyone else gives the incorrect answer!That holds true for people of any age in peer pressure situations.
It can be hard to walk away from peer pressure, but it can be done. Pay attention to your own feelings and beliefs about what is right and wrong can help you know the right thing to do. Inner strength and self-confidence can help you stand firm, walk away, and resist doing something when you know better.What is the main idea of the passage?
| A．Peers have a good effect. |
| B．Children give in to peer pressure. |
| C．Peer pressure is hard to stop. |
| D．Peer pressure. |
The underlined word “shoplift” probably means to_______.
| A．do shopping | B．carry goods for shops |
| C．steal in the shop | D．take the lift upstairs in the shop |
The writer will NOT agree that_______.
| A．only children change their correct answers to incorrect ones because of peer pressure |
| B．peers have an effect on each other |
| C．peer pressure can be got rid of |
| D．peers will believe in themselves if there are other peers who agree with them |
The writer intends to _______ by writing the passage.
| A．warn peers to separate from each other |
| B．tell peers to follow others |
| C．show it is hard to walk away from peer pressure |
| D．persuade peers to do what they think is the right thing |
IS THERE LIFE ON EARTH
There was great excitement on the planet of Venus(金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.
The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20 000 light years ago).Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility(可行性) of a manned flying saucer(飞碟) landing on Earth.A press conference was held at the Venus Institute of Technology.
“We have come to the conclusion,based on last week's satellite landing,” Pro. Zog said,“that there is no life on the Earth.”
“How do you know this?” the science reporter of the Venus Evening Star asked.
“For one thing, Earth's surface in the area of Manhattan is composed of solid concrete(混凝土)and nothing can grow there. For another, the atmosphere is filled with carbon monoxide(一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.”
“What does this mean as far as our flying saucer program is concerned?”
“We shall have to take our own oxygen with us, which means a much heavier flying saucer than we originally planned. ”
“Are there any other hazards that you discovered in your studies?”
“Take a look at this photo. You see this dark cloud floating over the surface of Earth? We call this the Consolidated Edison Belt. We don't know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there.”
“If what you say is true, won't this set back the flying saucer program several years?”
“Yes, but we shall proceed as soon as the Grubstart gives us the added funds.”
“Prof. Zog, why are we spending billions and billions of zilches to land a flying saucer on Earth when there is no life there?”
“Because if we Venusians can learn to breathe in an Earth atmosphere, then we can live anywhere.”During the week of great excitement the Venusian scientists succeeded in getting important information on whether they can_______.
| A．land a satellite with Venus astronauts on Earth |
| B．make a firstrate flying saucer |
| C．get a Earth Being to Venus |
| D．direct a flying saucer into Manhattan |
According to Prof.Zog,the Venusians will have to take their own oxygen with them when they carry out their flying saucer program because_______.
| A．they need it on their way to the planet of Earth |
| B．the Earth's atmosphere is filled with deadly gases |
| C．oxygen is far from enough in the area of Manhattan where the saucer is to land |
| D．there is no air on the planet of Earth |
The “dark black cloud” on the photograph refers to_______.
| A．the polluted air floating over the surface of Earth |
| B．the mass of tiny drops of water floating above Earth |
| C．the things that are unknown to everybody |
| D．the dark clouds gathering before a storm breaks |
The author wishes to call our attention to the fact_______.
| A．that modern man has polluted his environment to such an extent that he might destroy himself if he went on like this |
| B．that there is no point in spending billions and billions of zilches to land a flying saucer on Earth |
| C．that pollution has become so serious a problem on Earth that even Venusians find life there unbearable |
| D．that it is difficult, if not altogether impossible, to land a manned flying saucer on Earth |
After an extra day in space,the crew of Discovery returned to Earth,landing at Edwards Air Force Base in California early on Tuesday morning.The shuttle and its crew spent two weeks in space,most of it aboard the International Space Station.It was the first flight of NASA's spaceshuttle fleet since February 2003,when the shuttle Columbia came apart while reentering Earth's atmosphere.
NASA officials delayed Discovery's return for one day because of cloudy weather in Florida,where the shuttle was supposed to lanD. On Tuesday morning,mission controllers directed Discovery to a landing site in California,where the skies were clear.The crew members will have to wait until Wednesday to see their families when they all meet together in Houston at the Johnson Space Center.
Discovery had a very busy mission in space,compared to past missions.The space shuttle docked with the International Space Station most of the journey,delivering badly needed supplies and repairing damaged parts.The crew spent a lot of time testing new repair techniques on their own shuttle,conducting three different spacewalks(where astronauts exit the space shuttle to do work outside).On the third spacewalk,astronaut Steve Robinson went underneath the shuttle to remove material sticking out from between the spacecraft's protective tiles.
There were concerns in the last remaining days of Discovery's mission that a torn heat blanket—another shield against overheating in the space shuttle—may pose a problem to crew members. NASA officials and technicians worked on ways that the crew could fix the problem, but later decided it was not a risk.
With the shuttle and its crew safely back on firm ground, NASA is hailing this mission, labeled STS114,as a huge success. “I hope this shows people that we're coming back,” NASA spaceflight chief Bill Readdy said after Discovery's successful landing. “We've got some more work to do. We know what we need to do and we'll do it.Which of the following isn't included in the jobs of the shuttle Discovery?
| A．Delivering supplies to the International Space Station. |
| B．Conducting different spacewalks. |
| C．Testing new repair techniques. |
| D．Finding the cause why the shuttle Columbia came apart. |
But for the cloudy weather, the shuttle Discovery would have landed_______.
| A．in Florida a day earlier | B．in Florida a day later |
| C．in California a day earlier | D．in California a day later |
Which is the most probable period of time that Discovery was aboard the International Space Station?
| A．Six days. | B．Two weeks. |
| C．Nine days. | D．Two weeks and an extra day. |
What's the best title for the passage?
| A．Another Huge Success of Discovery |
| B．Welcome Back, Discovery |
| C．Discovery and International Space Station |
| D．Discovery Survives a Risk |
