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: Why does the writer mention the fact that "selfie" was added to an online dictionary? Options: A: To inform readers where to find the meaning of the word. B: To recommend the dictionary to readers. C: To show that the online dictionary is widely used. D: To indicate that the word has become very popular.

Read the article and select the best answer. Article: The Swiss army knife is a popular device that is recognized all over the world. In Switzerland, there is a saying that every good Swiss citizen has one in his or her pocket. But the knife had poor beginnings. In the late nineteenth century, the Swiss army issued its soldiers a gun that required a special screwdriver to take it apart and clean it. At the same time, canned food was becoming common in the army. Swiss generals decided to issue each soldier a standard knife to serve both as a screwdriver and a can opener. _ was a lifesaver for Swiss knife makers, who were struggling to compete with cheaper German imports. In 1884, Carl Elsener, head of the Swiss knife manufacturer(maker) Victorinox, seized that opportunity with both hands, and designed a soldier's knife that the army loved. It was a simple knife with one big blade , a can opener, and a screwdriver. A few years after the soldier's knife was issued, the "Schweizer Offizier Messer," or Swiss Officer's Knife, came on the market. Interestingly, the Officer's Knife was never given to those serving in the army. The Swiss army purchasers considered the new model with a corkscrew for opening wine not "essential for survival," so officers had to buy this new model by themselves. But its special multi-functional design later launched the knife as a global brand. After the Second World War, a great number of American soldiers were stationed in Europe. And as they could buy the Swiss army knife at shops on army bases, they bought huge quantities of them. However, it seems that "Schweizer Offizier Messer" was too difficult for them to say, so they just called it the Swiss army knife, and that is the name it is now known by all over the world. Question: Who gave the name "the Swiss army knife" to the knife discussed in the passage? Options: A: Carl Elsener. B: Swiss generals. C: American soldiers. D: German businessmen.

Q: Read the article and select the best answer. Article: Do you always forget where you placed your keys or your purse? What was the name of the movie you saw last week? The major cause of your forgetfulness may be linked to what you store in your body, not in your short-term memory bank. Tests continue to show that people with enough Vitamin B-2 do well in memory exams. The "B" could stand for "brain", if you're one of many with limited instant recall. And the number one source of that vitamin is sunflower seeds. Even when you're sleeping or relaxing, your brain is still at work. Although it makes up just two percent of your total body weight, it uses up to 30 % of the calories you take in each day. For it to work properly, it must be fed. Even if you're not a breakfast eater, that meal is the best way to prepare your brain for the day. A quick and easy English _ with peanut and butter in it, a glass of milk, and an orange, might be what your brain may be asking you the first thing in the morning when you feel your head is in a fog. Having sunflower seeds and fruit between meals adds more muscle to that hungry, demanding organ. Vitamin B-1 also helps the memory, and that is found in eggs, meats and nuts. In Chinese culture, walnuts are known as the fruit for a long life because it is believed that they feed both the kidneys and the brain. And according to Chinese culture, if you keep those two important organs in good working order, you'll live longer. However forgetful you are, just keep in mind the letter "B", which will help you to "bear in mind almost everything" even on those days when life's challenges are sending you in a billion directions. Question: What can we conclude from the passage? Options: A: Two percent of our brain is still active when we are sleeping or relaxing. B: What we eat seems more important than what we learn in terms of memory. C: It doesn't make much difference to our brain whether we have breakfast or not. D: Life's challenges have no effect on our memory, if dealt with in a proper way.
