Read the article and select the best answer. Article: Our society reports many negative messages about bicycling in traffic. Bicycling in traffic is considered by many to be reckless and sometimes rude. The most common advice given to cyclists is to avoid busy roads that provide convenient access to important places, which means they should only go to unpopular destinations on undesirable and inconvenient roads. Another popular idea is that cyclists should stay as close to the edge of the road as possible in order to stay out of the way of cars. Getting in the way of cars is considered to be an invitation to death, because car drivers are often expected to run into anything that is slower or more vulnerable. Going together with motor traffic used to be regarded as a nice idea for cyclists, but today it is thought to be suicide. Roads are believed to be designed for cars and not for bicycles. Inferior bicycles may hold that they have the right to use the road, but they had better stay out of the way of superior users or they will be "dead right". As a result of these "common-sense" beliefs, bike safety programs developed by motoring organizations and "pedestrian-style" cyclists during the 20th century attempted to teach cyclists to provide a clear path to motorists at all times by hugging the edge of the road, riding on sidewalks so cyclists can see when to get out of the way. Some towns tried to prohibit bicyclists from operating on important roads or roads without shoulders. Engineering projects designed for bicycle safety have involved construction of side paths to get cyclists off roads and bike lanes to keep cyclists out of the way of motorists. The benefit of these efforts is to protect cyclists from collisions from behind, which are widely believed to be the greatest danger to cyclists and caused by cyclists' failure to keep up with the desired speed of motor traffic. This is the taboo that harms the bicycle transportation policy: that bicyclists must be kept out of the paths of motorists or they will surely be killed. Question: Why do many people do not agree that people should ride bicycles on roads? Options: A: Most people think roads are designed for cars not for cyclists. B: People riding bicycles are considered to be inferior. C: People's riding on the road is against the law of the country. D: People riding bicycles are not experienced.

Read the article and select the best answer. Article: Dear Mr. Plant, I am an enthusiastic camper and longtime X-Ports customer, but after being offended for the third time at your Sierra Vista location, I am writing to complain about your impolite employees. Several months ago ,I bought a tent that leaked the first time I used it and wanted it replaced .  When I took it back, your employees accused me of tearing it myself. I left not only withm1, torn tent, but no refund  and no satisfaction. A  couple of weeks ago ,  I bought a sleeping bag that was supposed to sleep two people comfort-ably.  It didn't.  Your employees refused to give me my money back even though I had the receipt. I was asked to leave the store, again with no satisfaction. To my misfortune, my latest purchase , of a piece of camping equipment at your store proyed to be another disappointment.  The propane    camp stove I bought didn't work properly. When I returned to exchange it, the rude clerk refused to help me because I did not have my sales receipt. It was an even exchange! He said that I was a problem and even asked if I had seen what products I-could purchase at one of your competitor's stores at comparable prices.  Was he accusing me of something? Why would I have brought a receipt for an even exchange? Why  would I know the price at other stores? Furthermore, the clerk called security and forced me to leave your store-without my camp stove! How can I go camping now? The tent leaks, the sleeping bag is just wrong, and I don't have a stove to keep warm ! Who is going to refund my money for my stove? Who is going to help me get over the abuse I suffered in your store? You, as the area manager must clear these matters up for me immediately! I am sending copies of this letter to your main office and the Sierra Vista Store. Sincerely , Ima Kumpanee Question: The clerk didn' t want to exchange the stove for Ima because  _  . Options: A: the clerk was offended B: Ima destroyed it herself C: Ima didn' t have the receipt D: the clerk had given Ima the refund

Read the article and select the best answer. Article: The African elephant, the largest land animal remaining on the earth, is of great importance to African ecosystem . Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna  surroundings in which it lives, therefore _ of existence for millions of other animals that live in its habitat. It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas . In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters. Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well. What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem. Question: What is the passage mainly about? Options: A: Disappearance of African elephants. B: Forests and savannas as habitats for African elephants. C: The effect of African elephants' search for food. D: The eating habit of African elephants.
