Read the following article and select the best answer. Article: Perhaps it is hard to imagine that a bad tooth could be deadly. But doctors in the Washington area say a twelveyearold boy died last month of a tooth infection that spread to his brain. They say it might have been prevented if the boy had received the dental care he needed. Experts at the National Institutes of Health say good dental care should start at birth. They say breast milk is the best food for the healthy development of teeth. Breast milk can help slow bacterial growth and acid production in the mouth. When baby's teeth begin to appear,you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies,and use them very gently. The use of fluoride to protect teeth is common in many parts of the world. This natural element is often added to drinking water supplies. The fluoride mixes with enamel ,the hard surface on teeth,to help prevent holes,or cavities from forming. But the American Academy of Pediatric Dentistry points out that young children often swallow toothpaste when they brush their teeth. The group notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully supervised when they brush their teeth. And only a small amount of fluoridated toothpaste,the size of a green pea,should be used. Parents often wonder what effects sucking a thumb or sucking on a pacifier might have on their baby's teeth. Dental experts generally agree that this is fine early in life. The American Academy of Family Physicians says most kids stop sucking their thumbs by the age of four. If it continues,the group advises parents to talk to their child's dentist or doctor. It could influence the correct development of permanent teeth. Question: Which one of the followings is NOT true according to this passage? - Dental care should be given to babies as soon as they are born. - Special toothbrushes should be used for babies. - Breast milk and fluoride are helpful to protect baby teeth. - Dental experts suggest stopping babies sucking their thumbs.

Read the following article and select the best answer. Article: Earthquake is not an unfamiliar word to us as it is frequently covered on the news report. However, I never have the idea that it will take place in my city. But the truth is that it happened. When the building began to shake, I thought it was dizziness caused by long-time nonstop work and colleagues also kept silent till one of them shouted, "The chair is shaking." Then we came to understand it was not personal feelings, and we started to find the reason--the weak foundation of the building, or earthquake (in a joking tone), but we still kept doing what was in hand. It was kind of _ when I looked back, because of our slow reaction and stupid response. It was said that the staff in another building next to us all ran out of the building with their handbags; some of them even drove away. On hearing that, I thought it was a bitexaggeration . Did they really have to do so? It was only 20-second mild shaking. But now, when I totally get to know what happened, I change my mind. It is not over-reacting, but natural self-protection response. Luckily it's only the aftershocks; otherwise I guess I would be frightened to death. The aftershocks make me think what I'm going to do in case of earthquake, which I would never give a second thought before. I don't know what's on their mind for people who are on the spot of the earthquake, be frightened, at a loss, or simply running away, or trying to get contact with friends or... It is hard to imagine the picture and even harder to imagine what's next. For the first time, I have the feeling of insecurity. Humans are so fragile when they face the sudden disasters. Question: Why did the author and his colleagues still keep working when the building began to shake? - Because they thought the earthquake was slight. - Because they thought the earthquake was just aftershocks. - Because they didn't take the shake seriously. - Because there were no signs of earthquake at that time.
Because they didn't take the shake seriously.

Q: Read the following article and select the best answer. Article: Google is testing its newest high-tech device, Google Glass. Most of the technologies for Google Glass are already available on smart phones. Google has taken those same technologies and added them to eyeglass frames . The company describes the glasses as wearable computers that would change the way people view others and the world. "Google Glass is a tiny computer that sits in a lightweight frame, and rests neatly above your eye and it makes exploring and sharing the world around you a lot easier," said Chris Dale, the Senior Manager of Communications for Google Glass. The glasses have a tiny video screen and a camera that connect wirelessly to the Internet through WIFI, a smartphone, or a tablet computer. You can make and receive calls, send and receive texts, take pictures, record video or search the web. You control Google Glass using your voice, and a touchpad on the right arm of the frame. Professor Marcia Dawkins is among a select group of people who have been given a chance to test out Google Glass. "I thought this is something I definitely need for my classroom and hopefully for my personal life too." The Professor's Google Glass looks like a pair bright orange glasses, without the actual glass. But there's a tiny rectangular glass at the top right-hand corner. Through that glass, she has been recording video while biking. She also has been able to talk to her sister in Thailand, and she plans to use the device to teach a public speaking class. But not everyone is excited about Google Glass. Some are concerned about possible risks to privacy. John Simpson is the director of the privacy project at Consumer Watchdog. "It is going to allow people to come in and spy on you and record that, without you knowing what is going on." Filmmaker Chris Barrett showed just how easy it is to record people without them knowing it. His glass captured a man getting arrested after a fight. He shared the video on You Tube. Also some are concerned about the use of facial recognition technology on Google Glass. But Google... Question: While cycling, the Professor has used the Glass to _ . - record video and chat - send emails - teach a class - spy on others
A: record video and chat
