Language learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners. Most children will "obey" spoken instructions some time before they can speak, though the word"obey"is hardly exact as a description of the eager and delighted co- operation usually shown by the child. Before they can speak, many children will also ask questions by gestures and by making questioning noises. Any attempt to study the development from the noises babies make to their first spoken words leads to considerable difficulties. It's agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves out as particular expression like delight, pain, friendliness and so on. But since these can't be said to show the baby's intention to communicate, they can hardly be regarded as early forms of language. It is agreed too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new words to their store. This self - imitation leads out to deliberate imitation of sounds made or words spoken to them by other people. The problem then arises to the point at which one can say that these imitations can be considered as speech. It is a problem we need to get our teeth into. The meaning of a word depends on what a particular person means by it in a particular situation and it is clear that what a child means by a word will. change as he gains more experience of the world. Thus the use, at seven months, of" mama" as a greeting for his mother cannot be dismissed as a meaningless sound simply because he also uses it at another time for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself. I doubt, however , whether anything is gained when parents take advantage of his ability in an attempt to teach new words. The speaker implies that _ . A) even after they have learnt to speak, children still enjoy imitation B) children who are good at imitating learn new words more quickly C) children no longer imitate people after they begin to speak D) patents can never hope to teach their children new sounds

Climate change could affect food supplies, water resources, human health and homes. If greenhouse gas emissions keep increasing at the current rate, global temperature is expected to rise between 2degC and 6degC by 2100. This doesn't sound much, but a 5degC change is the difference between the current warm period and an ice age. Global warming leads to other changes in the climate: melting ice, more evaporation , changes in geographical patterns of rainfall, heavier downpours separated by longer dry spells, more frequent heat waves, more intense hurricanes, and sea level rise. These changes could affect crop growth as drought, increased evaporation and shrinking glaciers disrupt water supply. Some crops could suffer heat stress. While there may be benefits in some regions, overall climate change is likely to have a negative impact on global food supplies. The impacts of climate change on agriculture will vary widely around the world. A global temperature rise of 1-2 degC is expected to increase food production in some regions, particularly mid-latitude areas. But in tropical regions even a small amount of warming could reduce crop yields. A temperature rise of 3 degC or more could threaten global food resources, as all regions are likely to experience negative impacts overall. Freshwater resources could also diminish, especially in tropical regions, as rain patterns change and evaporation speeds up. Some communities could lose essential melt water as glaciers disappear, while more intense rainfall and hurricanes could cause more flooding, leading to water pollution and bacterial diseases such as cholera becoming more widespread. Climate change could lead to a variety of health impacts - both positive and negative. On the negative side, scientists anticipate more cases of malnutrition, heatstroke and waterborne diseases such as cholera. Although some populations will benefit from a reduced risk of cold-related illnesses such as _ , overall a warming world is likely to have negative effects on human... According to the passage, climate change has both positive and negative effects on _ . A) food supplies and buildings B) freshwater resources and homes C) human health and food supplies D) human health and homes

According to the Small Business Association, more than 50 percent of all small businesses fail within the first five years. This is not the case for Apiary Fund CEO, Shawn Lucas. Shawn has grown a very successful business focusing on teaching people how to trade foreign currencies. The Apiary Fund not only gives their traders some of the best Forex education possible but also gives their traders money to trade with. The Apiary Fund had a slow start but has now become a company that recently hit $1 billion in trader volume . The Apiary Fund's success has come from the great business concept, and work ethic . * Business Concept The Apiary Fund has a very special but effective business concept, which Shawn Lucas discovered many years ago. You are probably wondering, where did this business concept come from? Shawn, while working as a Financial Advisor, received a phone call one day from a man he hadn't ever spoken to before. The man asked Shawn to go with him to China to do an analysis of a Chinese company's trading systems. The company at the time was under investigation for a possible violation of intellectual property rights. He agreed to go and before he knew it he was on a plane to China. During the analysis of this Chinese company Shawn noticed the company had a very effective business method. He noticed that the risk manager had created a system that protected the company from rarely posting a losing day. The risk manager made this all possible by putting restrictions on the amount a trader could lose. If one of the traders lost even a small amount the risk manager would then be notified . Shawn left China with a business concept that would later consume much of his life. After returning home, Shawn was devoted to creating a similar risk management system as the Chinese company had created. That risk management system turned into a successful business called the Apiary Fund. * Work Ethic The business concept alone didn't magically make the Apiary Fund into a booming business. The Apiary Fund became... What's the main idea of the passage? A) How to make a small business successful. B) The analysis of a Chinese company. C) Shawn Lucas, an Apiary Fund CEO. D) Successful businesses are hard to start.
