To extinguish （熄灭）different kinds of fires, several types of fire extinguishers have been invented. They must be ready for immediate use when fire breaks out. Most portable （手提式的）kinds operate for less than a minute, so they are useful only on small fires. The law requires ships, trains, buses and planes to carry extinguishers.
Since fuel（燃料）, oxygen and heat must be present in order for fire to exist, one or more of these things must be removed or reduced to extinguish a fire. If the heat is reduced by cooling the material below a certain temperature, the fire goes out. The cooling method is the most common way to put out a fire. Water is the best cooling material because it is low in cost and easy to get.
Another method of extinguishing fire is by cutting off the oxygen. This is usually done by covering the fire with sand, steam or some other things. A blanket may be used do cover a small fire.
A third method is called separation, which includes removing the fuel, or material easy to burn, from a fire, so that it can find no fuel.
The method that is used to put out a fire depends on the type of fire. Fires have been grouped in three classes（级别）. Fires in wood, paper, cloth and the like are called Class A fires. These materials usually help keep the fire on. Such fires can be stopped most readily by cooling with water.
1.If a fire breaks out on a bus, which of the following should be ready there for you to use?
A. Sand B. An extinguisher C. A blanket. D. Water
2.To cover a small piece of burning wood with a basin in order to stop the fire is an example of _______.
A. separating the fire B. cutting off the oxygen
C. removing the fuel D. reducing the heat
3.In choosing how to put out a fire, we should first be clear about_______.
A. when it breaks out B. how it comes about
C. what kind it is D. where it takes place
4.What would the author probably discuss in the paragraph that follows?
A. Another class of fires B. Another type of extinguishers
C. How fires break out. D. How fires can be prevented.

People like different kinds of vacations. Some go camping. They swim, fish, cook over a fire and sleep outside. Others like to stay at a hotel in an exciting city. They go shopping all day and go dancing all night. Or maybe they go sightseeing to places such as Disneyland, the Tai Mahal or the Louvre.
Some people are bored with sightseeing trips. They don’t want to be “tourists”. They want to have an adventure— a surprising and exciting trip. They want to learn something and maybe help people too. How can they do this ? Some travel companies and environmental groups are planning special adventures. Sometimes these trips are difficult and full of the world. Some volunteers spend two weeks and study the environment. Others work with animals. Others learn about people of the past.
Would you like an adventure in the Far North ? A team of volunteers is leaving from Murmansk, Russia. The leader of this trip is a professor from Alaska. He’s worried about chemicals from factories. He and the volunteers will study this pollution in the environment. If you like exercise and cold weather, this is a good trip for you. Volunteers need ski sixteen kilometers every day.
Do you enjoy ocean animals ? You can spend two to four weeks in Hawaii. There, you can teach language to dolphins. Dolphins can follow orders such as “Bring me the large ball”. They also understand opposites. How much more can they understand ? It will be exciting to learn about these intelligent animals. Another study trip goes to Washington State and follows orcas. We call orcas “Killer Whale” , but they’ re really dolphins—the largest kind of dolphin. These beautiful animals travel together in family groups. They move through the ocean with their mothers, grandmothers and great-grandmothers. Ocean pollution is chasing their lives. Earthwatch is studying how this happens.
Are you interested in history ? Then Greece is the place for your adventure. Thirty-five hundred years ago a volcano exploded there, on Santorini. This explosion was more terrible than Krakatoa or Mount Saint Helens. But today we know a lot about the way of life of the people from that time. There are houses, kitchens, and paintings as interesting as those in Pompei. Today teams of volunteers are learning more about people from the past.
Do you want a very different vacation ? Do you want to travel far, work hard and learn a lot? Then an Earthwatch vacation is for you.
1.According to the passage, on an adventure trip, people ______________.
A. may not spend much time on sightseeing
B. won’ t meet some difficulties or hardships
C. can’t enjoy themselves .
D. can’t learn anything
2.If you want to learn something about people of the past, you can ___________
A. join the team to Hawaii
B. join the team to the Far North
C. join the team to Washington
D. join the team to Greece
3.The word “intelligent” in paragraph 4 means __________________.
A. exciting B. beautiful C. large D. clever
4.Which of the following is false ?
A. Some people find sightseeing trips boring.
B. Earthwatch is planning various special adventures
C. The life of orcas is under threat.
D. Many volcano explosions broke out 3, 500 years ago in Greece.

Scientists may have found a way to reduce shortage of type O blood. Type O is the kind of blood that hospitals most often need. What the researchers are testing is an easier way to make type O blood out of other kinds of blood.
There are four main kinds of blood. Most people born with one of these four: Type A,Type B, Type AB or Type O. Type O can be safely given to anyone. So it is commonly used when a person is injured or sick and has to have blood.
The differences among blood types are linked to whether or not red blood cells contain certain kinds of sugar molecules(分子). These molecules are found on the surface of the cells.They are known as antigens (抗原). These antigens are found with type A, B and AB blood but not with type O.
More than twenty-five years ago, scientists found that the antigens could be removed to create what they called universal-type cells. They could be removed with chemicals called enzymes(酶). But large amounts of enzymes were required to make the change.
Doctor Henrik Clausen of the University of Copenhagen in Denmark led the study. The next step, he says, is to complete safety tests. The team is working with the American company ZymeQuest to test the new method. If it meets safety requirements(*k)and is not too costly,it could become a widely used life-saving tool to increase the supply of universal blood.
1.How do scientists deal with the problem of lacking type O blood?
A.Hope more people to donate type O blood.
B.Make the most of the present type O blood.
C.Develop new ways of using type O blood.
D.Make type O blood out of other kinds of blood.
2.What make people have different kinds of blood?
A.Sugar molecules in red blood cells.
B.People's different living conditions.
C.Peoples various immune systems.
D.The variety of peoples cells and genes.
3.What can we infer from the text?
A.Type O blood can be safely given to anyone
B.Antigens could easily be removed to create universal blood.
C.A Danish company wanted to involve itself in studying blood.
D.The new method is not safe enough to be put into use in hospitals now.
4.What is the best title for the text?
A.Four different kinds of blood
B.A new way to make type O blood
C.The latest research on blood type
D.Find the proper type of blood

Brisbane, the capital of Queensland, is a lively city that is home to many different types of tourist attractions. In its early stages, the city grew as the agricultural and mining(采矿) industries grew, until it developed into the cultural city that it is today. It is also the third largest city in Australia.
Brisbane is a river city, although close to the coast, with the Brisbane River running through it. It is surrounded by hills and full of bridges. It is also very easy to get to a number of attractions such as the Gold Coast and the Sunshine Coast from Brisbane.
Brisbane has a number of theatres including the Lyric Theatre, Cremorne Theatre and the Playhouse Theatre which are part of the Queensland Performing Arts Centre in South Bank.
The area of South Bank is popular with visitors and locals especially for its relaxed parkland and manmade beach area which is popular with all ages. During the evening this area is very popular for romantic walks and the many shows.
Another place that is very popular with visitors especially young people is the suburb(郊区) of Fortitude Valley. It is home to the amazing Chinatown, great restaurants, popular nightclubs and bars and so on. It's not a suburb for those who like peace and quiet.
Brisbane is a great place to cycle, with wonderful cycle tracks(自行车道) near and along the river. If you get tired along the way, you can always get on a bus or the City Cat (central area transport service). You can take a bus with your bike. But you'd better avoid the time of day when most people are traveling to or from work, because you won't be allowed on with a bike at that time.
Brisbane offers plenty of things to do with activities and tours such as hot air ballooning, rock climbing, and even climbing the Brisbane Story Bridge. For more information about Brisbane tours, please click here.
