There are many kinds of change, and many different things than cause change. People need to realize the changes, to learn to see them, and to learn what causes change.
Human beings must solve many problems so that they can continue to live successfully. War is one of these problems. Disease and natural disaster are problems. Having enough food and energy for the growing number of people in the world is a problem. Most problems can be solved, but some are impossible to solve. The way in which people solve problems affects how long and how well they can live.
As people solve their problems, they change things, and changes often cause new problems for people and for other living things on the earth. Sometimes the new problems seem even worse than the old ones. Human beings will probably never stop having problems to solve. Can you use your imagination to describe a world that has no problems at all ?

举一反三
Earth Day activities can include learning something about technology like cars that are more environmentally friendly and special houses that save energy and water．An organization called the Earth Day Network encourages people to use clean energy which doesn’t pollute the environment．Most of our energy comes from fossil fuels (化石燃料) that are found underground． Coal， oil and natural gas are examples of fossil fuels．Fossil fuels come from plants and animals that lived millions of years ago． Burning fossil fuels to create energy pollutes the air and water． Many scientists think that burning fossil fuels also increases the temperature of the earth． To reduce the use of fossil fuels． scientists are experimenting with hydrogen-powered (氢化发动的) cars． These cars don’t pollute the air like gas-powered cars．
Some scientists guess that by 2025, fossil fuels will run out．When people can no longer use gasoline， they may use fuel cells instead． Fuel cells use hydrogen to create energy． People do not need to worry about hydrogen running out， because it is renewable and replaceable．
In Washington， D.C.， a few people drive cars that run on fuel cells． When these cars need more energy, drivers can go to a hydrogen pump．The first hydrogen pump for the public opened in November 2004， marking an important step toward a cleaner environment．
小题1:what can we learn from the passage?
A．Fossil fuels don’t pollute the air．
B．Hydrogen-powered cars make less pollution．
C．Many drivers are driving hydrogen-powered cars．
D．We can find many hydrogen pumps in the USA．
小题2:How long may people still be able to use fossil fuels?
| A．Twenty years． | B．Over thirty-eight years． |
| C．More than ten years． | D．About seventeen years． |
| A．Scientists are producing more hydrogen-powered cars． |
| B．Some people drive fuel-cell cars in Washington． |
| C．Fossil fuels come from plants and animals． |
| D．We can learn about environmentally friendly technology from Earth Day activities． |
| A．When we use them to create gasoline． |
| B．When people get them from the underground． |
| C．After being burned to get energy． |
| D．After getting them from a hydrogen pump． |
| A．it will be used up | B．it can be used for creating energy |
| C．it will pollute the environment | D．it will be cleaner |
1．Water．
A person need at least 1/2 gallon of water daily just for drinking． Store at least 1 gallon of water per person per day and be prepared for a 72-hour period．It is suggested that you buy bottled water． Keep bottled water in its original container and do not open it until you need to use it． Also， do check the “use by” date．
2．Food．
It’s always a practical idea to keep a supply of nonperishable （不易腐烂的）food on hand． Have an enough supply of canned food， powdered milk， dried fruits, nonsalted nuts and canned juices for at least 72 hours．
3．Flashlights （手电筒） and spare batteries．
Keep a flashlight beside your bed, at your place of work, and in your car． Do not use matches or candles after an earthquake until you are sure that no gas leaks．
Prepare a battery-powered radio and spare batteries． Most telephones will be out of order, so radios will be your best source of information．
4．Clothes．
If you live in a cold place， you must think about warmth． You might not have heat after an earthquake． Think about your clothing and bedding supplies．
小题1:Why should people prepare themselves for an earthquake?
| A．Because earthquakes can be known before they happen． |
| B．Because earthquakes take place without warning． |
| C．Because earthquakes usually take place in the neighborhood． |
| D．Because it’s people’s daily work to prepare the earthquakes． |
| A．A person should prepare 0.5 gallon of water for one day． |
| B．You’d better use your own containers to keep water． |
| C．You’d better open the bottled water when you buy it． |
| D．You shouldn’t open the bottled water until you need it． |
| A．powdered milk | B．fresh vegetables | C．dried fruits | D．canned juices |
| A．we need to prepare some supplies only at home． |
| B．a telephone is the most important prepared thing． |
| C．flashlights but not matches are first used after earthquakes． |
| D．clothes are used to protect your head． |
| A．some warm clothes and bedding supplies | B．some hot water |
| C．some batteries | D．some flashlights |
An African tigerfish(老虎鱼) was seen jumping out of the air and catching a flying bird. The African tigerfish has bright red fins and very sharp teeth. There have been rumors(传闻) this kind of fish preys on(捕食) birds since the 1940s, but no one was able to catch one.
"The whole action of jumping and catching happens so quickly that after we saw it, it took all of us a moment to really understand what we had just seen," said Nico Smit from Environmental Sciences and Management at North-West University.
Smit and his research team saw it at a lake in the Mapungubwe National Park in South Africa during summer. They found about 20 fish feeding on birds in the morning. Those birds may be out early to look for food, but we will never know for sure!

| A．Nobody has heard of the rumors about the tigerfish before. |
| B．It took Smit a moment to understand what he had seen about the fish. |
| C．The interesting findings happened in a lake in the afternoon. |
| D．The birds were caught by the tigerfish because they were out too early for food. |
| A．In a poster. | B．In a tour guide. | C．In a newspaper. | D．In a story book. |
| A．The early fish gets the bird. |

Why do airplanes take longer to fly west than east?
It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon (大气现象) known as the jet stream (气流). The jet stream is a very high altitude (=" above" sea level) wind which always blows from the west to the east across the Atlantic. So the planes moving at a constant air speed go faster from the west to the east when they are moving with the wind than in the opposite.
What would happen if the gravity on Earth was suddenly turned off?
Supposing we could magically turn off gravity. Would buildings and other buildings float away? What happened would depend on (依靠) how strongly the things were attached (吸附) to the earth. The earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string, it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Turning off’ gravity would be like letting go of the string. Things not attached to the earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling (=" top" surface of a room). Most things outside would fly off into space.
小题1:What information can we get from the first passage?
| A．It is the jet stream that affects how fast airplanes fly. |
| B．Planes go slower when they are moving with the wind. |
| C．It takes more time to fly from NY to London than from London to NY. |
| D．The jet stream always blows from the east to the west across the Atlantic. |
| A．send for | B．move quickly | C．come out | D．grow quickly |
| A．buildings and other structures would float away |
| B．trees and buildings would not so easily fly off |
| C．something around your head would not float away |
| D．everything outside buildings would fly off into space |
| A．It takes seven hours to travel from London to New York. |
| B．The earth is moving at a high speed. |
| C．Things on the earth will float away if there’s no gravity. |
| D．Things not attached to the earth would fly off in a straight line. |
| A．In a research paper. | B．In a short story. |
| C．In a travel magazine. | D．In a student’s book |
Every day, Mr Xie goes to Dongzhimen Bus Stop, and gives help to at least 1,200 people asking for directions. During holidays, the number may be even 3,500. There are more than 50 roads and streets meeting at Dongzhimen, and at least 100 thousand people pass by there daily.
The reporter of Beijing Youth Daily had an interview with Xie. At that time, he arrived at the bus stop and placed his little table with maps and guidebooks written by himself on it.
"Is it really free to ask you for the way?" said a person from southeast China
"Of course," answered Xie with a smile. "Quite a number of people have asked me the same question. I am a volunteer."
The reporter found that at least 5 people came to ask him for the way in a minute, and Xie told them the way patiently and gave every one of them a note with his words on it.Xie has a husky voice. People think that it"s because of the result of the things he is doing.
