In order to make relationships between people strong, sites like Facebook, Twitter and QQ have become a daily "must visit" site. In fact, many people spend all day in front of the computer or are busy with their phones only to spend time on these sites. Social networking sites provide facilities that enable people to communicate with their friends without spending time meeting them in person. In addition, they can play games. But what is quite surprising is that these sites not only give you pleasure, but can also increase risks of diseases in your body. Despite their primary purpose, these sites make people more isolated . "Sending a message through sites can cause side effects that are very big in the body's biological changes," said Dr Aric Sigman, a psychologist, according to DailyMail. Increased isolation may alter the workings of immune response to the feelings of anger and others. People become angry easily. In the journal, Dr. Sigman says that it can increase the risk of cancer, strokes, heart attacks and dementia . Researchers found that the amount of time people used to meet face to face had decreased greatly since the increased use of the electronic media in 1987. To save time, people prefer to meet virtually rather than face to face; Education today even uses an online system that allows school-aged children not to come out of their rooms. Parents spend less time with their children, like the cases in England. The habit of having dinner together decreases, while the number of people who choose to work online at home increases. "The electronic media may also reduce the ability of children and adults in social interaction, as long as they are isolated. Social networking sites should help us improve the quality of life, but what happens is the opposite, they are not a tool to improve, but a tool to replace," said Dr Sigman. Question: Facebook and Twitter are designed to _ . Options: A: help people find their true happiness in life. B: make it easier for people to send messages C: improve the influence of social networking sites D: help people keep in touch with others conveniently

Read the article and select the best answer. Article: When I was a seven-year-old girl, I used to go door-to-door with my mother to ask the residents for donations to the American Lung Association. Some would give a few coins; others, on rare occasions, a whole dollar; but most would silently shake their heads. No matter what the amount was, my mother always thanked the givers, wrote their names and addresses on her large envelope, and placed the money inside. And then we returned to our apartment, and my mother counted the money. The yield didn't match the effort: I don't think she collected more than $10. Still, she sent the collection to the organization. Even as a child, I knew my mother's actions were great, which aroused my pride in her. Asking poor people to give to an organization which aimed to help others wasn't what you did. Other charities gave to these folks; you didn't ask them to give. To them , her efforts likely seemed foolish. But to me, her efforts had an influence on me as I grew up. Although my charitable giving is modest, I faithfully and regularly donate to the organization which is aimed at fighting AIDS; to stop hunger, and homelessness; to support public broadcasting, the arts, and public education; and to heal families. And I volunteer my time to teach little girls and fix our badly broken public schools. I do these things because I believe I've been given much, so much is required of me. I never asked my mother why she collected those donations, and, besides, the lung cancer that killed her twenty-one years ago prevents me from asking now. But had I asked, my mother's response would have been simple:"Because I can."That's what she would have said. But from that look in her eyes and her daily efforts to make life a bit brighter, I know she also acted on hope that tomorrow would be better and that her actions somehow would make a difference. Question: The author believes that his mother collected those donations mainly because . Options: A: she hoped she could spread the spirit of donation B: she hoped she could make others know her kindness C: she hoped she could protect herself from lung cancer D: she hoped her efforts would make a difference to others

D

It wasn't invented in the United States, and it didn't originate in Germany. No, the world's first hamburger comes from China. If you're scratching your head right now, you're not alone. But Chinese hamburgers are very real and they definitely predate the hamburgers we call our own in the U.S. Known as rou jia mo, which translates to "meat burger" or "meat sandwich", they consist of chopped meat inside a pita-like _ , and they've been around since the Qin Dynasty, from about 221 BC to 207 BC. Despite the differences between this Chinese street food and our American-style burgers, the rou jia mo has been called the world's first hamburger. The rou jia mo originated in the Shanxi Province of China, and is now eaten all over the country. It's typically prepared and eaten on the street. The dough for the bun, or mo, consists of a simple mixture of wheat flour, water and maybe yeast. Of course recipes may vary, but this basic equation makes for a chewy and subtle pillow for the delicious filling. While the mo is traditionally baked in a clay oven, today it's often fried in a pan. They may look a little like Chinese steamed buns or baozi, but the dough for those are, of course, steamed, not baked or fried. The meat filling might consist of chopped pork, beef, lamb or chicken that has been stewed with a variety of spices, like ginger, cloves, coriander and star anise. You might also find herbs like cilantro or greens like lettuce garnishing the sandwich. Question: Which of the following is TRUE? Options: A: The mo people eat today is baked in a clay oven. B: The world's first hamburger which was originated in the Shanxi Province of China is popular around the world. C: The rou jia mo has a history of more than 2200 years. D: The rou jia mo and American-style burgers share a similar cooking process.
