user: Read the following article and answer the question. Article: I have always known my kids use digital communications equipment a lot. But my cellphone bill last month really grabbed my attention. My son had come up to nearly 2,000 incoming text messages, and had sent nearly as many. Of course, he was out of school for the summer and communicating more with friends from a distance. Nevertheless, he found time to keep a summer job and complete a college course in between all that typing with thumb. I was even more surprised to learn that my son is normal. "Teenagers with cellphones each send and receive 2,272 text messages a month on average, " Nielsen Mobile said. Some experts regret  that all  that  keyboard jabber  is making our  kids stupid, unable to read non-verbal cues such as facial expressions, gestures, posture and other silent signals of mood and attitude. Unlike phones, text messaging doesn't even allow transmission of tone of voice or pauses, says Mark Bauerlein, author called The Dumbest Generation: How the Digital Age Stupefies Young Americans and Jeopardizes Our Future. Beyond that,  though,  I'm not sure I see as much harm as critics of this trend.  I' ve posted before on how I initially tried to control my kids' texting. But over time, I have seen my son suffer no apparent ill effects, and he gains a big benefit, continuing contact with others. I don't think texting make kids stupid. It may make them annoying, when they try to text and talk to you at the same time. And it may make them _ when buzzing text message interrupt efforts to noodle out a math problem or finish reading for school. But I don't see texting harming teens' ability to communicate. My son is as accustomed to nonverbal cues as any older members of our family. I have found him more engaged and easier to communicate with from a great distance. because he is constantly available by means of text  message and responds with faithfulness and speed. Question: What would be the best title for this passage? Answer:
For Teens, Texting Instead of Talking

It is everybody's second language. It is easy to understand, although you can't hear it. It is sign  language. When you wave to a friend who is across the street, you are using sign language. When you smile at someone, you are saying, "I want to be friendly", but you are not using speech. You are using body language. When you raise your hand in class, you are saying, "Please ask me. I think I know the correct answer." Babies who can't talk can point at things. They are using sign language. A policeman who wants to stop traffic holds up his hands. He is using sign language. Many years ago, a French priest, Charles Michel de Epee, became interested in education for deaf people. He invented a finger alphabet  . It is still in use. People can make the sign  for letters and spell words with their hands, and deaf people can read and understand them. Soon there were schools for the deaf in many countries. The only university for the deaf is Gallaudet College in Washington, D.C. Today, in the United States, there are special TV news programs for deaf people. The newsreader tells the news in sign language. At the same time, the words appear on the TV screen. The actors in the Theatre of Deaf don't spell every word. Sometimes they use hand signs. When they put two hands together, it means sandwich. They can make a roof with their hands when they want to show a house. One finger in front of an actor's mouth can mean quiet. You can talk to people who are behind windows that are closed. And when you go swimming with your friends, you can have conversations under water. How many hand signs do you use every day?

Read the following article and answer the question. Article: A study found that young people have a stronger and more unpleasant scent   than the elderly,while elderly people's smell was the most distinctive,less intense and unpleasant. Researchers said the change in our smell is driven by the chemicals we release through our glands   and the bacteria on our skin. To test whether or not it really exists,scientists collected a series of samples from three groups of 12 to 16 donors,aged 20 to 30,45 to 55 and 75 to 95.Volunteers wore special T-shirts fitted with underarm pads   as they slept for five nights,after which the pads were cut up and put in glass jars. A separate group of 41 people aged 20 to 30 was then asked to smell two jars at a time and asked which group of the donors was older,as well as rating how strong and unpleasant each smell was. When asked to specify whether a particular sample was from a young,middle aged or old person,they were much more successful at identifying older people. Despite being the most distinctive,the older people's smell was also rated as being obviously less intense and less unpleasant than those from the other groups. Researchers said their findings appeared to contradict people's negative ideas about the old person's smell but admitted other factors,like smelly breath or skin,could be to blame for its bad reputation. "Similar to other animals,humans can give off body scents that allow us to identify biological age,avoid sick individuals and pick a suitable partner. Elderly people have a distinctive scent that younger people consider to be not very unpleasant. This was surprising given the popular conception of old age scent as smelly. However,it's possible that other sources of body scents,such as skin or breath,may have different qualities," said Dr Johan Lundstrom,who led the study. Question: Which of the following ages of people have the chance to participate in the study? Answer:
77

Read the following article and answer the question. Article: Baby sign language is a growing movement. Pointing to a color1ful flower, Campbell lifts her baby's soft hand, and rapidly moves it from one side of his nose to the other as she sniffs  ."Flower!" she says loudly. Gregory smiles and looks carefully. It could be a year before Gregory, 4 months old, can speak, but now his mother hopes to communicate with her baby through sign language. Like others around the world, Campbell is part of a growing movement of parents teaching hearing babies simple signs to communicate before they can talk. The baby sign language has been more popular in recent years. The movie,"Meet the Fockers",where the main character teaches his young grandson to sign, makes it well developed. Babies generally begin to talk between 12 and 15 months, but babies can use sign language to communicate before they learn how to speak. "We know they are learning language faster than they are able to show you with their speech production because that system takes a long time to develop." says McRoberts, director of developmental research at the Haskins Laboratories. "They are understanding words before they are able to say them. From around 16 to 18 months, they might say 50 words but understand 200.They understand short sentences well." says McRoberts. Studies have shown deaf children learn to use sign language earlier than hearing children learn to speak meaningfully. As to whether hearing babies can communicate earlier with sign language, McRoberts says,"I think that's still unknown. It may not. I'm very interested in that very question." Question: Many parents teach their babies sign language mainly to   _  . Answer:


assistant: communicate with their babies
