Reporting the news through photos is called photojournalism. At times photojournalists tell their stories through a single picture. At other times, they use a group of pictures to tell a story. Each picture is like a chapter in a book, which can do more than record the facts. 72 .
Jacob Riis was among the first photojournalists, 73 Riis believed that poverty caused crime and he used photos to help him prove his point. A few years later , the photos of small children working in factories by Lewis Hine shocked the public .Hine’s pictures helped bring about laws to protect such children.
74 It takes science to have the photo come out clearly and art to make a photo that has a good design and expresses feeling. Photojournalists make an actual record of what they see. A photo, however , can be both a work of art and an actual record. It can record an important event as a beautiful or exciting picture.
As historical and artistic documents(文献), photos can become more important over time . Today photojournalists still have their pictures appear in newspapers and magazines.75.
A. Hundreds of pictures may have to be taken in order to get one or two really good photos. B. You are welcome to take a photo. C. It can also be a strong force for social change. D. They also publish them in books and on the Internet AB. It can repeat the facts, too. AC. He took pictures of parts of New York City where the poor lived. BC. Photos record the beauties of nature. |
Imagine living on the edge of a vast desert, which is moving quietly closer to your village every day and covering your fields. The desert is on the move. This is called desertification.
Desertification occurs in regions close to an already existing desert. 71 The first is over-use of water in the area. There is not enough water in any case, and if it is not carefully used, disaster can follow. As time goes on, water shortages make farming more and more difficult. In some places, locals can remember local lakes and marshes which were once the homes for all kinds of fish and birds. 72 Farmers leave the land, and fields are replaced by deserts.
The second cause is misuse or over-use of the land. 73 Ploughing(耕) large fields and removing bushes and trees means that the wind will blow away the soil. Once the soil is lost, it is hard to replace, and if there is rain, it has nowhere to go, and brings no benefit.
74 Every spring, the skies over some of eastern cities, thousands of kilometers away from the deserts, can be darkened by sandstorms. Dust from deserts can have a great effect on weather systems. While desertification is perhaps being partly caused by global warming, these sandstorms can make global warming worse by adding to what is known as the greenhouse effect.
What can be done to slow down or stop the process of desertification? A great deal of work is already under way. Obviously first steps are to find new water sources. 75 Some types of grass also hold the soil together, and stop the wind taking it. Without these efforts, it will be harder and harder to stop the world’s deserts in their tracks, and more and more farmers will give up and head for cities. The lesson to be learnt lies beneath the sand.
A.It generally arises from two related causes. |
B.It is not only the farmers and villagers who suffer. |
C.They have been completely buried by the sand now. |
D.Scientists are doing the research on the cause of desertification. |
F. Tree planting can help, by providing barriers between desert and rich field.
G. This means that the wrong crops are planted, and need more water than is available.
To extinguish (熄灭) different kinds of fires, several types of fire extinguishers have been invented.__71__ 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, oxygen (氧气) 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.__72__ 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.
__73__ 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.__74__
The method that is used to put out a fire depends upon the type of fire. Fires have been grouped in three classes.__75__ These materials usually help keep the fire on. Such fires can be stopped most readily by cooling with water.
A.Fire extinguishers should be available everywhere in our life. |
B.They must be ready for immediate use when fire breaks out. |
C.Where a fire breaks out, there will surely be unavoidable damage. |
D.Fires in wood, paper, cloth and the like are called Class A fires. |
F.If the heat is reduced by cooling the material below a certain temperature, the fire goes out.
G.It includes removing the fuel, or material easy to burn, from a fire, so that it can find no fuel.
