People who eat at home most of the time have better nutrition than those who go out to eat , a recent study shows. Cornell University professors Lana Hall and Karen Bunch interviewed(,) 3900 people in the survey. "People who eat less than 30 percent of their food away from home eat the most nutritiously," they said. "In general, Americans don't have nutrient, except for iron and calcium," they reported. They have the opposite problem----over--consumption , especially of fat. The food at many fast food restaurants is often low in vitamins. "People who eat more than 30 percent of total calories away from home eat foods that are generally low in nutrients per calorie," the professors said. More calories and enough nutrient intake are required to achieve. One of the major health risks is eating too much fat. The professor found than fat consumption became greater as income went up. It also went up in houses where the female worked. This is probably because these people eat more highly processed foods. The passage is about _ . A) Eating and Health B) The Life Style in Modern Society C) Fast food in the USA D) Dining out Lowers Nutrient Intake

The more we learn about the octopus , the more intelligent we discover they are. Octopuses possess not one but nine "brains", one in each of their legs and a central brain behind the eyes. Octopuses can solve problems, can be trained to learn behavior and are extremely good at figuring out how to get out of an aquarium and get into food. We can learn a lot from an octopus. An octopus doesn't have a backbone, which doesn't mean that they lack nerve. On the contrary, their nervous system, which goes all the way down each leg, is very complex. They are able to take in a lot of information about their world and seem to be able to remember, learn and adapt to new situations. The suckers on their long legs can not only feel, but also taste. Each sucker works individually, so an octopus can just focus on one leg or one sucker. Their eyesight is sharp. Although their brains are quite small in comparison to ours, they still have very large brains for invertebrates . They have many physical characteristics of a human brain. Perhaps you've seen the video of an octopus in a German aquarium that learned to open a jar to get its food. Octopuses have also been taught to go through mazes and to pick out different shapes of patterns. Their short term and long term memory seems to be excellent. It is thought that octopuses are as intelligent as dogs in their capacity to learn certain behavior, solve problems, and make use of objects. In the movie "Octopus Intelligence: Deep Sea Aliens," some species of octopuses are letting young octopuses watch the adults in order to train them. If this keeps up, in a hundred thousand generations the octopus may rule the seas. Clearly, there is more to an octopus than just a lot of legs. Which of the following statements about the suckers of the octopus is true? A) Each one can work by itself. B) They can taste but can't feel. C) Each leg has only one sucker. D) Each one has an eye,

Ques: Some people were eating and drinking in a coffee house. A young woman was sitting alone at a table. She was wearing a beautiful diamond necklace. There was an ugly man at a table not far from her. He was looking at her necklace all the time. Suddenly the lights went out. The coffee house was in darkness. The woman started to shout. She was very frightened. A few minutes later the lights came on again. The woman was crying. Her necklace was missing. The manager quickly closed all the doors. He telephoned the police. No one could get out of the coffee house. The policemen soon came. The police inspector told his men to search everyone. The necklace was not on anyone. They then searched the whole coffee house. The necklace couldn't be found. The police inspector then looked at the faces of all the people in the coffee house. He saw the ugly man and looked at the man carefully. He went up to the man and picked up the bowl of soup that was on his table. He then poured the soup into a glass. The necklace fell out. The policemen caught hold of the man and took him away. The young woman was happy to get back her necklace. The necklace was stolen by _ . A) a beautiful girl B) an old woman C) a young student D) an ugly man
Ans: D
Wind turbines are efficient sources of cheap energy but also a source of concern as their huge spinning blades frequently kill birds and bats. A new type of wind generator developed in Spain offers a creative solution to that problem. In 2002, Spanish inventor David Yanez saw a short film about the Tacoma Narrows Bridge in the U.S., collapsing in strong wind. It was a vivid example of the powerful vibrations wind can create when it blows past a long pole, such as a car antenna or even a stick of bamboo. It gave him the idea for a new type of wind-energy generator. "The initial philosophy or spirit was to create a generator of dreams that had all the qualities one would want: It should be as cheap as possible, need as little maintenance as possible, the setup as simple as possible," he said. Yanez and his friend Raoul Martin took the idea to an engineering firm, where they were told it would never work. Undiscouraged, they started experimenting on their own in a small wind tunnel they built. Good initial results were repeated by a larger working model called Vortex installed in a nearby field. "What we have is a mast , which is the top piece and acts as a blade," Yanez said. "It's constructed from the same material as a conventional generator, and what it does is it oscillates , transmitting the oscillation to a conventional alternator, which by its own oscillation converts the wind's energy into electric energy." Yanez said the output of the 6-meter-tall generator, and even that of smaller models, was better than expected. The Vortex creates about 30 percent less energy than a comparable bladed wind turbine, but it is lighter and cheaper to build and maintain. It is made mostly of reinforced plastic and has very few moving parts. Also, it does not create noise and--even more important for many environmentalists--it does not present a threat to passing birds. The current prototype works at wind speeds ranging from 1.5 to 7 meters per second. The inventors say the next step is building a 12.5-meter tall... The author mentions a short film about the Tacoma Narrows Bridge to show _ . A) what the initial philosophy or spirit was B) what inspired Yanez to create the generator C) how the bridge was destroyed in strong wind D) how wind creates powerful vibrations
