He put it in a window of his house and took a picture of his garden. That was the first photo. The next important date in the history of photography was in 1837. That year, Daguerre, another Frenchman, took a picture of his reading room. He used a new kind of camera in a different way. In his picture you could see everything very clearly, even the smallest thing. This kind of photo was called a Daguerreotype. Soon, other people began to use Daguerre's way. Travelers brought back wonderful photos from all around the world. People took pictures of famous buildings, cities and mountains. In about 1840, photography was developed. Then photographers could take pictures of people and moving things. That was not simple. The photographers had to carry a lot of films and other machines. But this did not stop them, for example, some in the United States worked so hard. Mathew Brady was a famous American photographer. He took many pictures of great people. The pictures were unusual because they were very lifelike. Photography also became one kind of art by the end of the 19thcentury. Some photos were not just copies of the real world. They showed our feelings, like other kinds of art. Question: This passage tells us _ . Options: A: how photography was developed B: how to show you ideas and feelings in pictures C: how to take pictures in the world D: how to use different cameras

Article: Researchers at Sweden's KTH Royal Institute of Technology say they have found further proof that the wolf ancestors of today's dogs can be from southern East Asia -- findings that are contrary to theories placing the birth place in the Middle East. Dr Peter Savolainen, KTH researcher in evolutionary genetics, says a new study released Nov. 23 confirms that an Asian region south of the Yangtze River was the principal and probably the only region where wolves were domesticated by humans. Research data show clearly that dogs are descended from wolves, but there's never been scientific agreement on where in the world the domestication process began. "Our analysis of Y-chromosomal DNA now confirms that wolves were first domesticated in Asia south of Yangtze River -- we call it the ASY region -- in southern China or Southeast Asia," Savolainen says. The Y data supports previous evidence from mitochondrial DNA. "Taken together, the two studies provide very strong evidence that dogs appeared first in the ASY region," Savolainen says. Archaeological data and a genetic study recently published in Nature suggest that dogs originate from the Middle East. But Savolainen rejects that view. "Because none of these studies included samples from the ASY region, evidence from ASY has been overlooked," he says. Peter Savolainen and PhD student Mattias Oskarsson worked with Chinese colleagues to analyse DNA from male dogs around the world. Their study was published in the scientific journal Heredity. Approximately half of the gene pool was universally shared everywhere in the world, while only the ASY region had the entire range of genetic diversity. "This shows that gene pools in all other regions of the world most probably originate from the ASY region," Savolainen says. "Our results confirm that Asia south of the Yangtze River was the most important -- and probably the only -- region for wolf domestication, and that a large number of wolves were domesticated," says Savolainen. In separate research published recently in Ecology... Question: What is special about mitochondrial DNA? Options: A: It is only used in studying evolutionary relationships. B: It alone can provide hard evidence for Savolainen's research. C: It is the most useful in finding out the birth place of dogs. D: It comes from the mother of most animals and plants.

Article: Sarah Williams went to a boarding school.Here is one of the letters she wrote to her parents from the school: Wentworth Girls' school Beachside July 20th Dearest Mom and Dad, I'm afraid I have some very surprising news for you.I have been very naughty and the school headmaster is very angry with me.She is going to write to you.You must come and take me away from here.She does not want me in the school any longer.

As I was smoking, I heard footsteps coming towards the room.I did not want a teacher to catch me smoking, so I threw the cigarette away. Unfortunately, the cigarette fell into the waste-paper basket, which caught fire. There was a curtain near the waste-paper basket which caught fire, too.Soon the whole room was burning. The headmaster phoned the fire department.The school is a long way from the town and by the time the fire department arrived, the whole school was on fire.Many of the girls are in hospital. The headmaster says that the fire was all my fault and you must pay for the damage.She will send you a bill for about a million dollars. I'm very sorry about this. Much love, Sarah P.S.None of the above is true, but I have failed my exams.I just want you to know how bad things could have been. Question: Why did Sarah tell her parents the story about the fire? Options: A: She wanted to worry them B: She wanted to make them laugh C: She wanted to make them less angry at the real news D: She wanted to warn them about what the headmaster was going to do

Read the article and select the best answer. Article: Without proper planning,tourism can cause problems.For example,too many tourists can crowd public places that are also enjoyed by the inhabitants of the country.If tourists create too much traffic,the inhabitants become annoyed and unhappy.They begin to dislike tourists and to treat them impolitely.They forget how much tourism can help the country's economy.It is important to think about the people of a destination country and how tourism affects them.Tourism should help a country keep the customs and beauty that attract tourists.Tourism should also advance the wealth and happiness of local . Too much tourism can be a problem.If tourism grows too quickly,people must leave other jobs to work in the tourism industry.This means that other parts of the country's economy can suffer. On the other hand,if there is not enough tourism,people can lose jobs.Businesses can also lose money.It costs a great deal of money to build large hotels.Airports,first-class roads,and other support facilities needed by tourist attractions.For example,a major international class tourism hotel can cost as much as 50 thousand dollars per room to build.If this room is not used most of the time,the owners of the hotel will lose money. Building a hotel is just a beginning.There must be many other support facilities as well,including roads to get to the hotel,electricity,sewers to handle waste,and water.All of these support facilities cost money.If they are not used because there are not enough tourists,jobs and money are lost. Question: Too much tourism can cause all these problems EXCEPT _ . Options: A: a bad effect on other industries B: a change of tourists' customs C: over-crowdedness of places of interest D: pressure on traffic
