Article: Many of us enjoy doing it: you turn on the camera on your mobile phone and hold it at a high angle--- making your eyes look bigger and your cheekbones more defined. You turn to your best side and click. There it is - your selfie. Over the past year, "selfie" has become a well-known term across the globe. This August the Oxford dictionary added the word to their online dictionary and define it as: "A photograph that one has taken of oneself, typically with a smartphone or webcam and uploaded to a social media website." Today it's not difficult to find social networking pages full of photos people have taken of themselves and their friends. And selfie culture has become especially relevant for young people. As many as 91 percent of teenagers have posted photos of themselves online, according to a recent survey by the US Pew Research Center. So what are the reasons for the rise of selfie culture? "The craziness about the selfie celebrates regular people," Pamela Rutledge, a professor at the Massachusetts School of Professional Psychology, told Vogue magazine. "There are many more photographs available now of real people than models." Posting selfies also allows you to control your image online. "I like having the power to choose how I look, even if I'm making a funny face:' Samantha Barks, 19, a high school student in the US, told Vogue. In addition to self-expression and documentation , selfies "allow for a close friendship for long-distance friends, because you can see each other's faces every day", wrote Casey Miller at The Huffington Post. But US psychologist Jill Weber is concerned that selfies might lead to social problems. "There's a danger that your self-esteem may start to be tied to the comments and '1ikes' you get when you post a selfie, and they aren't based on who you are - they're based on what you look like," Weber told Vogue. "When you get nothing or a negative response, your confidence can decrease." Question: Many people post photos of themselves online to _ . Options: A: make fun of themselves B: become powerful C: beautify themselves D: choose how they look

Q: Read the article and select the best answer. Article: As rain begins to fall from the clouds, it is very pure. However, as it falls through the air it dissolves some of the gases in the air. It also collects bits of dust and microbes that are floating in the air. When the rain reaches the ground it begins to pick up more dust and dirt. Many kinds of mineral substances dissolve in the water. Sand and mud cannot dissolve in water. Since water is so important to us, it is very important that the water we use should be clean. Otherwise, we might get some of the diseases that are carried by water. Many microbes are harmful. They are so small that we cannot see them. These microbes must be removed or killed before the water is suitable for drinking. For example, microbes of diseases like cholera live well in water. If the water supply is not clean, people who drink this water may get these diseases. Thus, to provide people with clean water, the government purifies the water. Purification is a long process and includes three stages: storing, purifying and distributing . The first stage is storing. Man-made lakes are used for this purpose. Water from the rains, other lakes, streams and rivers is collected in the lakes. This water is usually dirty and muddy. In the second stage, water from the man-made lakes is filtered in a special pond. Stones, sand and other unwanted tiny things are caught in it. After that, tiny microbes are still present in the water. These microbes are removed by "airing" the water and by adding a chemical substance called chlorine to the water. This kills all the microbes in the water. After this, the water can be safely used for drinking. The third stage is the distribution of the purified water to homes, hospitals, offices, factories and other places. This is done through a network of pipes of various sizes. These pipes must be made of a suitable material. Question: What can we know about man-made lakes? Options: A: It is used through the whole process of purification. B: Only rain water can be collected and stored in it. C: Water collected can be stored and filtered in it. D: Water from it contains a lot of impure substances.
