The wonderful world which lies before us today has been put up by hardworking men with clear heads and inventive mind, and these who follow them along life's road will improve on their efforts. It is sometimes necessary to question and even to disbelieve some of the statements made by experts. Action or experiment can often end an argument or achieve a breakthrough. When men were wondering whether it was possible to reach India by sailing westwards from Europe, and whether there was any land on the other side of the Atlantic Ocean, Christopher Columbus decides to act. He gathered some men, invited them to go on board his three ships, and set out across the dangerous waters of the Atlantic Ocean. He was successful in finding land, but it was not India. The result of his action was that the arguments came to the end. Any young man who wishes to do research must be courageous enough to question old beliefs and do some original thinking about them. Although we seem to know so much, there are many things we don't know. Even when we pull an atom to pieces, we do not really know what the pieces are, we often do not reach the reality behind what we discover, and the more we learn, the better we realize our ignorance. Question: Christopher Columbus decided to set out his trip because he wants to _ Options: A: travel round the world B: bring words into action C: discover the truth with action D: bring the argument to an end

The first English people were fishermen there, and they named the place Greenwich, meaning "green village". Later the English kings and queens lived at Greenwich in their beautiful places. The name of the earliest palace was Placentia. Its windows were made of glass--the first in England. But trouble was coming to Greenwich. In 1649, a war started in England and for eleven years there was no king. The men who had worked for him at Placentia decided to live in the place themselves. They sold all its beautiful things, and bought small pieces of the palace garden with money. Finally, the war ended and King Charles II came back. But Placentia was falling down. So King Charles built a new and bigger palace, which is now open to the public. At this time, Charles was worried about losing so many of its ships at sea because their sailors did not know how to tell exactly where they were. So in 1675, Charles made John Flamsteed, the first astronomer in England, try to find the answer. Flamsteed worked in a new building on the high ground in Greenwich Park. From it with a telescope which he made himself, Flamsteed could look all round the sky. And he did, night after night, for twenty years. Carrying on Flamsteed's work a hundred years later, an astronomer called Harrison finally made a clock which told the time at sea, and helped sailors to know where they were.You can see Harrison's clock, still working, in Greenwich's museum of the sea. Because of Flamsteed's work, every country in the world now tells its time by Greenwich time. Question: The first English people living in the "green village" were _ . Options: A: sailors B: fishermen C: King Charles and his family D: The families of king and queens

Read the article and select the best answer. Article: Food for thought in the US Before I left for America, everyone warned me to watch my weight because it's easy to put on weight there. That's true. One thing I still cannot _ is the food and drink. Almost every American person loves sodas, especially those full of ice cubes. I remember the first day I came to my host family. When I asked them for a glass of hot water, they all looked at me and thought I was crazy! At my school there's no water dispenser but there's one in each classroom in China. All the American students drink water from taps outside the restrooms that are specially designed for drinking. The water is cold and the school doesn't have hot water. The most popular food here is hamburgers and French chips, which are junk food in China. Most students who eat at school prefer those to salads. They also eat lots of pizzas and hot dogs. As a result, you can always see some really fat people in school. Luckily, my host mom is really a great cook. She always makes food from different countries and eats a balanced meal every day. So I have a lot of fruit and vegetables. At my host family's home, they usually eat biscuits. These old-fashioned biscuits are low in fat and flavored with buttermilk, butter, and a bit of honey. Oh here comes the most interesting thing: the word "biscuit" in China actually means "cracker " here. Real biscuits are a kind of soft cake. I was also amazed by the rich kinds of food in American supermarkets and their reasonable prices. For example, one brand of yogurt has 20 kinds of flavors! You're sure to find one that you like. And most of the food provides you "light", "original" or "no sugar" options to choose from. Question: What is the main idea of the article? Options: A: To show how badly Americans need to change their diet. B: To tell about the American foods that she likes and dislikes. C: To show how much fun she has with her host family. D: To introduce food differences between America and China.
