Write a multi-choice question for the following article, with the given choices and answer: Article: Spider webs are one of the most fascinating examples of animal architecture. The most beautiful and structurally ordered are the round webs. The main function of the web is to stop and hold flying insects,long enough for the spider to catch them. In order to do so,the threads of the web have to stand the forces from large and heavy insects as well as environmental forces from wind and rain for at least a day in most cases. The round web is found to have two main characteristics. The first is its geometry,which consists of an outer frame and a central part from which threads radiate outward. Enclosed in the frame are capture spirals winding round and round from the web center out to the frame. The whole web is in tension and held in place by anchor threads,which connect the frame to the surrounding plants or objects. The second and perhaps most important characteristic is the material with which it is built. Spider silk is a kind of natural material that gives this lightweight fiber a strength comparable to that of steel, while at the same time making it very elastic . Two types of silk threads are used in the web. One is highly elastic and can stretch to almost twice its original length before breaking and, for most types of spiders, is covered in glue. This type is used in the capture spiral for catching and holding insects. The other is stiffer and stronger,and is used for the radius,frames and anchor threads,which allows the web to stand forces and to keep its structural strength through a wide range of environmental conditions. Options: A 1capture spiral 2 radius B 1radius 2 capture spiral C 1anchor thread 2 frame thread D 1frame thread 2 anchor thread Answer: D 1frame thread 2 anchor thread Question:

"Take them and let me go." she said. The robber was uncertain. He saw that the girl didn't care for the earrings at all, only trying to protect the necklace.

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: To "sacrifice" means to give up something for the sake of something else. We decided to sacrifice our luxurious city life to move to a seaside village with our children aged 9 and 3. In the city, we had a beautiful home and plenty of money but little real security because crime was on the increase every day. We never knew if we would all make it home safely each night. We were very happy in the new town but life was very difficult economically. Our income was very much dependent on tourism and the jobs at other times are few. Although many of the long-standing residents live well, it is a very competitive environment for newcomers. Reading the newspapers from the big cities assured us that we had made the right choice. There is so much violence and crime there! However, it was not always easy to explain .to the children why they could no longer have what they used to have, especially when our "rich" friends came from the city to visit. One day, one of our "rich" friends came to visit us. His son preferred riding in the back of our _ truck to his father's modern car. Our little daughter called me and said, "Mom, please help me explain to James why he is wrong. He said, 'today, if you don't have money you are nothing.' I know that is not true. If you do have money you share it with your friends and if they don't have money, you share it with them. That is what makes us all rich." This made me realize that the sacrifice was well worth it. Our kids have a solid set of values and they know that our most precious gifts are our good friends and a wonderful environment. Options: A The residents were all very poor. B Their children couldn't get what they had in the city. C It was hard to make a living. D They had few friends in their new environment. Answer: C It was hard to make a living. Question:
Answer: Why was it "a very competitive environment" for them according to the author?

Write a multi-choice question for the following article, with the given choices and answer: Article: Today, one can trace Venice's rich past from its buildings. Most cities can claim at least a handful of outstanding churches, palaces or houses of historical interest, but in Venice very nearly everything is remarkable, from the magnificent Piazza San Marco (St. Mark's Square ) and the palaces that line the Grand Canal to the centuries-old homes of simple fishermen. It would be easy to say that the city itself is an enormous museum if it were not for the fact it is so obviously alive. At first sight, Venice looks unbelievably permanent, an apparently complete Renaissance city so untouched by time that there seems no reason why it should not go on forever. Now the city is slowly sinking, as the clay on which it is built loses its elasticity and the massive wooden piles rot away. Flooding, such a rare occurrence a hundred years ago now happens several times each winter. The damage caused by the flooding is immense, and the fabric of the ancient buildings is now being further damaged by pollution from the mainland town as well as by the wash produced by the constantly increasing number of motor boats that speed up and down the canals. A further threat to Venice comes from the Venetians themselves, some of whom are not particularly interested in preserving the city as one of the wonders of the world and would prefer to see it modernized. "What better place is there for the meeting of dear friends? See how it glows with the advancing summer; how the sky and the sea and the rosy air and the marble of the palaces all glimmer and melt together." Thus wrote the famous author Henry James, of Venice, which provided the setting for his story "The Aspern Papers", in the nineteenth century. The Splendor of Venice has captured the imagination of artists for centuries --- and not just of the great painters and novelists. How tragic now that she is faced with the double threat of man and nature. Venice indeed will be lucky to survive. Options: A Venice can be regarded as a big museum B Venice is no longer a big museum C Venice is different from a big museum D Venice can never be a big museum because of its modernization Answer: A Venice can be regarded as a big museum Question:
