Article: Speech--the act of uttering sounds to convey meaning--is a kind of human action. Like any other constantly repeated action, speaking has to be learned, but once it is learned, it becomes a generally unconscious and apparently automatic process. As far as we can determine, human beings do not need to be forced to speak; most babies seem to possess a sort of instinctive drive to produce speech like noises. How to speak and what to say are another matter altogetner. There actions are learned from the particular society into which the baby is born; so that, like all conduct that is learned from a society--from the people around us--speech is a patterned activity. The meandering babble and chatter of a young child are eventually channeled by imitation into a few orderly grooves that represent the pattern accepted as meaningful by the people around him. Similarly, a child's indiscriminate practice of putting things into his mouth becomes limited to putting food into his mouth in a certain way. The sounds that a child can make are more varied and numerous than the sounds that any particular language uses. However, a child born into a society with a pattem of language is encouraged to make a small selection of sounds and to make these few sounds over and over until it is natural for him to make these sounds and not others. Question: We may say that a child has learned to speak if he_. Yes or no, is the answer "makes only certain sounds naturally"?
(A).
No

Article: Most American schools have boys and girls in the same classroom. But a public high school in the small, rural town of Boonsboro, Maryland, offers a special program called the Academy. Top students in the ninth and tenth grades can attend single-sex classes for math, science, English and social studies. The aim is to help teenagers keep their mind on their work by keeping males and females apart. What they really want to do is take that top group of kids and take them to the very highest level they can achieve there, so that they're prepared for college. Students are invited to enter this program after they finish middle school, and placement in the Academy is voluntary. However, they need high marks and test scores and strong teacher recommendations. They also need to be involved in activities. Almost 350 students have taken part in the Academy. It began as an experiment in 2010. Michael Bair has been at Boonsboro High for twenty years and directs the Academy. His ninth-grade English class for boys centers on books that he believes boys find interesting. He says that the novels the students are reading now are very manly novels. These novels deal with the arrogance of man and the pride of man which finally leads to man's downfall. One of those books, for example, is The Call of the Wild by Jack London. This classic story tells of a dog stolen from his home and sold to work as a sled dog in Canada's Klondike Gold Rush. Morgan Fleet, a senior at Boonsboro High, likes being in the Academy. She says boys and girls act differently when they are together in a classroom. She believes this difference seems to prevent her from developing herself because she's more focused on thoughts like "Oh, I wish they would shut up. Oh, what do they think of me?'' instead of focusing on "What's the homework? What's going on in this class? What's the lesson?". There is one activity that girls and boys in the Academy do together. At the end of the day, many of them stay and help tutor students who are having trouble in school. Question: What is the purpose of the Academy program? Yes or no, is the answer "To help students concentrate on study."?
(A).

Article: The sun is setting on a summer night.At the entrance of a deep,dark cave,a few bats fly out.Within a few minutes,millions and millions of bats are pouring out of the cave. Sounds like a scary horror movie? Believe it or not,this scene takes place all summer long,at Bracken Cave in Texas,where 20 million bats come out to feed on insects every night."It is magical,"says Jim Kennedy of Bat Conservation International in Texas."It is one of the most impressive animal movements on the planet." Every March or April,Mexican free-tailed bats migrate up to 1,600 kilometers from their winter home in Mexico to their American home in Texas,where they raise their young. Soon after they arrive,each mother gives birth to one baby.As many as 500,baby bats crowd into 30 cubic centimeters of space.and all those bodies create nice warm tem- peratures to keep them cozy and comfortable. If you have ever lost sight of your parents in a crowded playground,you may be won- dering how mother bats recorgnize their children.They use their sense of smell to tell which baby is theirs when it is time for the babies to have milk. When twenty million bats fly out of one cave opening,they make a column so thick that they show up on the radar at the nearby airport.It can take three hours for all of them to get out from the cave."You can feel the breeze from their wings,and see the plats wa- ving,"says Kennedy."The movement of all those wings makes a very relaxing soft sound.I've always thought it would make a great relaxation music to help you go to sleep. So much for bats being scary!" Question: What makes the scene so"impressive"? Yes or no, is the answer "The huge number of bats flying together."?
(A).
No
