Question: Article: Just five one-hundredths of an inch thick and light golden in color, the Lay's potato chip seems an unlikely weapon for global control. But its maker, Frito-Lay doesn't think so. "Potato chips are a snack food for the world , "said Salman Amin, the company's head of global marketing. Amin believes there is no corner of the world that can resist the attractions of a Frito-Lay potato chip. Frito-Lay is the biggest snack maker in America owned by Pepsico and accounts for over half of the parent company's $ 3 billion profits every year. But the U.S. snack food market is largely saturated ,and to grow, the company has to look overseas. Its strategy rests on two beliefs: first, a global product offers economies of scale with which local brands cannot compete. And second, consumers in the 21st century are drawn to "global" as a concept. "Global" does not mean products that are consciously regarded as American, but ones that consumers--especially young people--see as part of a modern, innovative world in which people are linked across cultures by shared beliefs and tastes. Potato chips are an American invention, but most Chinese, for example, do not know that Frito-Lay is an American company. Instead, Riskey, the company's research and development head, would hope they associate the brand with the new world of global communications and business. With brand concept a key factor, Riskey ordered a redesign of the Frito-Lay logo . The logo, along with the company's long-held marketing image of its chips, would help make the company's global development very easy. The managers admit that they try to change national eating habits to a food created in America, but they don't think that means economic imperialism . "We're making products in those countries, we're adapting them to the tastes of those countries, building businesses and employing people and changing lives , "said Steve Reinemund, Pepsico's chief manager.
Question: Amin's belief is that _ .
Options: (A) people all over the world enjoy eating their potato chips (B) the light golden color increases the attraction of their potato chips (C) they must find new ways to promote sales in their country (D) potato chips can hardly control the world market

Answer: C

Question: Article: People like to look in the mirror often when they have a young and beautiful face. However, when one grows old, nobody wants to see their wrinkled old face in the mirror any more. So, many old people seldom look at their faces in the mirror. This is completely wrong. According to Wu Zhenyun, a professor from the Psychological Research Institute under the Chinese Academy of Sciences, a person's willingness to look in the mirror can reflect his or her mentality. When people don't care too much about their age, they will try to carry themselves with ease and natural poise . They don't mind looking in the mirror to see their own faces. Some people even love to look in the mirror from time to time to see whether they keep a good appearance. In this way, mirror becomes their best friend that help them to look confident. On the other hand, some people are afraid of being old. They don't want to see the wrinkles on their face and their hair turning grey. So they don't want to look in the mirror. This actually reflects a negative attitude they hold towards life. In the long term, they might suffer from psychological pressure or some sort of depression, which is actually not a wise act. " Everyone can make themselves look charming at every age stage. If one is confident, one will always look beautiful, it shows that they accept themselves." professor Wu said. Mirror cannot only give confidence to one. By looking in the mirror, one can even find the traces of some diseases from one's own face.
Question: Why does the mirror become the best friend for some people?
Options: (A) Because it brings much confidence to them. (B) Because it makes them more beautiful. (C) Because it tells whether they are clean or not. (D) Because it helps them find their own faults.

Answer: A

Question: Article: Beavers are a very unique species in the world of nature and wildlife----they are architects. Their dams are fine examples of engineering. A pair of beavers will build a dam, using branches, mud and stones, across a river. The water held back by the dam flows over the bank on either side of the river, flooding the nearby ground and forming a pond. At some point in the pond the beavers then build their home, which is called a lodge. This consists of a cone-shaped pipe of branches and sticks of two to six feet in length held together with mud and stones, the top of which projects above the waterline. It serves as a shelter from the bad weather, a safety from enemies and a base for food supplies to be drawn upon in winter. From an engineering point of view the lodge could hardly be improved. Not only does it contain a central room just above water level, which is accessible only through underwater tunnels, but it also has "walls", one or more escape tunnels and an air hole at the top, which controls the temperature inside and gives air-conditioning. It is altogether a clever piece of construction, with all modern conveniences. It is, in fact, better protected against the effects of flooding than many human houses. Trees are essential to beavers. They eat the bark on the upper branches. But they must first _ the trees, using their four front teeth. With these sharp tools, it takes only a few minutes to cut down a tree. The engineering skill of beavers is to a large extent a result of their ability to use their front paws as hands. A female will carry her young held under her chin with her front paws, walking on her hind legs. A similar method is used by all beavers when transporting stones or mud, although they also carry such materials on their broad flat trails. The fore-paws are also used for digging and for dragging heavier pieces of wood.

Options: (A) the beaver's lodge (B) the beaver's engineering skills (C) the beaver's dam (D) the beaver's intelligence
