Read the following article and select the best answer. Article: "How far is the next village?" the American asks a man standing by the edge of the road. In some countries, because the man realizes that the traveler is tired and eager to reach his destination , he will politely say "Just down the road." He thinks this is more encouraging, gentler, and therefore the wanted answer. So the American drives through the night, getting more and more angry, feeling "being tricked". He thinks the man on purpose lied to him, for obviously he must have known the distance quite well. Had conditions been reversed , the American would have felt he was "cheating" the driver if he had said the next town was not too far, and if he would be sorry to the weary driver, he would say "You have a good way to go yet, it is at least fifteen miles." The driver might be disappointed, but he would know what to expect. Whether to be accurate or polite leads to many misunderstandings between people of different cultures. If you know the situation in advance, it is sometimes easier to recognize the problem. Question: The man at the roadside tells the American it is not far from the next village because he _ . - wants to encourage him to go further - doesn't know the exact distance at all - wants to help the man to decide whether to stop and have a rest - tries to play a trick on him
wants to encourage him to go further

Read the following article and select the best answer. Article: Thick dust rose and a large building collapsed. This was the scene in Zhu Zhou,Hunan Province on May 17. Nine people were killed and 16 injured. Things were similar in the Sichuan earthquake. Thousands of people were buried in the ruins and lost their lives. What if we could have warned them? People are always _ to find a way of preventing buildings' collapse. Better materials and technology help,but they are not a solution. Just like humans,a building has its own life cycle from "birth" to "death".If we know when a building is going to collapse,we can repair it in advance or get out of it before it falls. Now,scientists at the University of Illinois have developed a material that turns red before it breaks. The invention could be used in things like climbing ropes or bridge supports. The research was led by Nancy Sottos,a professor at the university's Beckman Institute,and Douglas Davis,a graduate research assistant. The secret behind the color--changing material is a type of molecule .A molecule is a group of atoms held together by chemical bonds. Imagine you and your friends standing in a circle,holding hands. Each person stands for one atom,your hands represent the bonds,and the entire circle represents a molecule. If one person lets go of his or her hands,the molecule changes color. The research team put the molecule into a soft material. When the researchers stretched the material,it turned bright red for a few seconds before it broke into two pieces. When they repeatedly stretched and relaxed the material,without breaking it,it only turned a little red. The major problem is that light can get rid of the red color. When the team shone bright light on the molecule,the broken bond was fixed,and the color disappeared. Scientists have yet to do more research before the color--changing molecules can be used outside the lab. Question: Which of the following is a WRONG statement? - Thousands of people died from the collapse of buildings in the Sichuan earthquake because they hadn't been warned. - There is no building that will never collapse. - A new material has been applied to buildings to warn people of collapse. - A color--changing material can turn red before it breaks.
(Answer)
A new material has been applied to buildings to warn people of collapse.

Ques: Read the following article and select the best answer. Article: Think about what you usually have for a meal: Is it a hamburger? What about vegetables? Would it surprise you to learn that what you eat can affect the whole planet? It can--in a big way. Scientists attending the American Association for the Advancement of Science meeting in Chicago presented new studies showing how food and its production affect the globe and its warming climate. It is generally believed that global warming is caused by the large amounts of greenhouse gases released into the atmosphere. One of these greenhouse gases is carbon dioxide. What does this have to do with food? A big part of the carbon dioxide comes from the process of making and eating food, the scientists reported in Chicago. The production of meat contributes to a lot of that carbon dioxide. The process of making a hamburger, for example, requires a lot of energy. A cow has to be fed and raised on farmland, and cow manure is a major source of methane --an especially powerful greenhouse gas. By the time a hamburger is finally served on a dinner plate, it has done great harm to the environment. The message from the research is clear: We can greatly reduce the production of greenhouse gases by eating less meat. All kinds of meat, the scientists reported, are harder on the planet than vegetables. To grow and eat a pound of potatoes, for example, sends less than one-quarter pound of carbon dioxide or other greenhouse gases into the air. So shifting our diet to less meat and more vegetables ,as it turns out, may do the world some good. Question: According to the passage , the writer seemingly intends to _ . - appeal to us to protect the environment by eating less meat food. - persuade us to develop a good eating habit to keep healthy - advise us to make less hamburgers in order to save energy. - encourage us to grow more vegetables to reduce greenhouse gases.
Ans: appeal to us to protect the environment by eating less meat food.

Question: Read the following article and select the best answer. Article: As the population of the planet increases, so does the number of homes, businesses, parking lots, schools, airports and roadways. All these structures use electricity and need to be lighted. Humans demand these lights. They want their homes more comfortable and they want their streets safe. The problem is that researchers are finding that all the light is having a negative effect on humans and wildlife as well. Less than 10 years ago I drove to a thinly populated section of my town, lay down in the middle of the road and watched an attractive meteor shower . The area was short of homes, street lights and traffic. If I did that today, I wouldn't be able to see the meteor shower as well. Due to the increase in street lights, I would surely be run over by a car. Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide pollution. If you've ever taken a flight at night, the view is beautiful, but you must remember that all the light you see wastes electricity. The crew of the space shuttles see an even bigger picture of how extensive the wasted electricity is worldwide. One of the saddest parts of light pollution is that most of it is unnecessary and most of the outdoor light that we use is wasted. One only needs to look at a row of street lights to see how much of the light shines upwards and lights the sky; a total waste of electricity. Additionally, somewhere electricity needs to be produced, and the production of electricity creates pollution by releasing greenhouse gases. This affects the air we breathe and our quality of life. Scientists are also studying the effects of light pollution on wildlife. Thousands of birds die each year when they crash into highly lighted buildings, as they become puzzled by the light. It has been long known that tiny baby sea turtles become lost and follow lights on the shore instead of heading towards the sea. Fortunately, light pollution is one of the easiest sources of pollution that can be corrected without a negative effect. Following some... Question: What can be inferred from the text? - We are almost at a loss how to deal with light pollution. - Global warming results in light pollution in some way. - Astronauts can't see clearly in space nowadays. - Some animals use natural light to direct their movements.
Answer:
Some animals use natural light to direct their movements.
