Q: Article: 1826, a Frenchman named Niepce needed pictures for his business .But he was not a good artist.So he invented a very simple camera .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 1837. That year, Daguerre, another Frenchman, took a picture of his studio. He used a new kind of camera and a different processs. In his pictures, you could see everything very clearly, even the smallest details. This kind of photograph was called a daguerreotype. Soon, other people began to use Daguerre's process. Travellers brought back daguerreotypes from all around the world. People photographed famous buildings, cities and mountains. In about 1840, the process was improved. Now photographers could take pictures of people and moving things. The process was not simple. The photographers had to carry lots of film and processing equipment. But this did not stop the photographers, especially in the United States, where from the 1840s daguerreotype artists were popular in most cities. Mathew Brady was a well-known American photographer. He took many pictures of famous people. The pictures were unusual because they were very life-like and full of personality. Brady was also the first person to take pictures of war. His 1862 Civil War pictures showed dead soldiers and ruined cities. They made the war seem more real and more terrible In the 1880s, new inventions began to change photography. Photographers could buy film readymade in rolls. So they did not have to make the film immediately. They could bring it back to their studios and develop it later, meaning that they did not have to carry lots of equipment. And finally, the invention of the small handheld camera made photography less expensive. With the small camera, anyone could be a photographer. People began to use cameras just for fun. They took pictures of their families, friends and favourite places. They called these pictures "snapshots". Photographs became very popular in newspapers in the 1890s. Soon magazines and books also used documentary photographs. These pictures showed true events and people. They were much more real than drawings. Photography had turned into a form of art by the beginning of the 20th century. Some photographs were not just copies of the real world. They showed ideas and feelings, like other art forms.

Q: Article: A euphemism (from the Greek words eu--well and pheme--speak) is a word or expression that is used when people want to find a polite or less direct way of talking about difficult or embarrassing topics like death or the bodily functions.Most people,for example,would find it very difficult to say in plain language that they have arranged for their sick old dog to be killed.They would soften the pain by saying:We had Ruby put down or We had Ruby put to sleep.Many people prefer to call someone plain than ugly,or cuddly rather than fat. Euphemisms are an important part of every language,but it seems that English has an evergrowing number of them.The nonnative speaker not only has to make sense of the euphemisms he hears,he also has to learn which euphemisms are appropriate in any particular situation.He might be aware that his American friend needs to use the toilet when she asks where the bathroom (or restroom,or comfort station) is,but he is less likely to guess that his English friend has the same need when he says he has to see a man about a dog.He might have learned,for example,that in the family way is a euphemism for pregnant.If,however,he says to his boss,"Congratulations!I hear your wife is in the family way," he would be using an expression that is too familiar for the circumstances. Schools are full of euphemisms.At Frankfurt International School,for example,the special lessons given to students who are having difficulties in their school subjects are called Study Center (in the middle school) and Academic Workshop (in the high school).Teachers rightly do not want to upset students or parents by being too frank or straightforward,and usually choose a softer word or expression to convey the same message.
Question: According to the passage,people use euphemisms in order to _ .
Options: (A) make themselves understood (B) avoid embarrassment (C) to sound straightforward (D) attract attention

A: B

Q: Article: The number of smokers in England is about 8 million. According to the Department of Health, smoking is the biggest cause of early death in the country. Smokers in England have been asked to give up smoking for 28 days this month, in an action backed by Cancer Research UK and the British Heart Foundation. Research shows people who manage not to light up for this length of time are 5 times more likely to kick the habit. Public health experts say campaigns that include a combination of hard-hitting ads and supportive messages work best. Quitting smoking can be difficult. However, people are much more likely to succeed if other people are doing the same than if they try to do it alone and _ . Robert West, Director of Tobacco Studies at University College London, points out how pressure from people around can prevent a smoker going on smoking. "We are social animals," he said. The action has met some doubts among readers of the BBC News Online website. Some compared it to asking people to stop eating as a way of fighting overweight. Others doubt the action's effectiveness. "Its weakness is that it fails to explain why a person smokes, and the reasons are as many as the number of smokers", says someone who signed as BluesBerry. Another reader, Cazz, has decided to give it some credit. He says:" Campaigns like this won't necessarily inspire the majority of smokers to quit, but may encourage those thinking about quitting to set a date and try. Surely it's worth a shot. "
