Question: Many American youngsters earn their own allowance by doing temporary jobs for their neighbors. Babysitting is one of the common of these jobs. Most couples do not have maids or relatives living with them, and they need to have someone watch the children if they want to go out. Another way is by mowing lawn in summer and clearing snow from sidewalks and driveways in winter. Many people mow their own lawns,but often people prefer to give the job to a neighbor's child. In winter, snow clearing from streets and highways is the government's responsibility. Homeowners or tenants, however, must clear sidewalks and driveways. Since clearing snow is very tiring, many people prefer to hire teenagers for this job rather than do it themselves. Besides, many American teenagers usually work two to three hours after school and all day on Saturday or Sunday at the local supermarket. They work as cashiers or stockroom clerks. Or they help customers carry things to their cars. Other favorite jobs are waiting on tables in restaurants or working part-time at stores or gas stations. By earning their own allowance,teenagers acquire a feeling of independence and a sense of responsibility which prepares them for a productive life in society. When it comes to clearing snow,what do many people like to do? A) Hire teenagers for this job rather than do it themselves B) They do it themselves. C) They hire their own children to do so D) They don't clean it at all.
Answer: A

Question: Standing in line for the latest iPhone at the Apple store, queuing for tickets to Wimbledon or even just waiting at the post office might just have got a lot easier. Japanese car-maker Nissan announces that it has just the thing to relieve the painful legs of tired queuers. The new system of 'self-driving' chairs is designed to detect when someone at the front of the queue is called, and automatically move everyone else one step forward in line. The new invention is shown off in a company video, which shows a busy restaurant with patrons waiting outside. In the video, diners are sitting in a row of chairs, but will not have to stand when the next hungry diner is called to a table. Instead, the chairs, equipped with autonomous technology that detects the seat ahead, move along a path toward the front of the line. When the person at the front of the queue is called, the empty chair at the front can sense it is empty and so moves out of pole position. Cameras on the remaining chairs then sense the movement and follow automatically. The system, which is similar to the kind used in Nissan's autonomous vehicle technology, will be tested at select restaurants in Japan this year, Nissan said. "It appeals to anyone who has queued for hours outside a crowded restaurant: it _ the boredom and physical pain of standing in line," Nissan added. Although Tokyo has some 160,000 restaurants, long queues are not uncommon. Chosen restaurants that meet the criteria will be able to show the chairs outside their restaurant next year. Nissan also released a short video showing the chairs being used in an art gallery, moving slowly in front of the various paintings to let viewers appreciate the art without the need to stand up. What can we know about "self-driving" chairs from the text? A) They are in hot demand like iPhones. B) They are intended for queuing diners. C) They are the inventions of a car company. D) They are completely different from vehicle technology.
Answer: C

Question: Could a grizzly bear move to your neighborhood? If you live in the U.S. West, the answer may be yes. People and grizzly bears are living closer together now. The grizzly bear is one of the largest meat-eating land animals in North America. In the early 1800s, about 50,000 grizzly bears lived there. Today there're far fewer bears. Settlers built cities and roads where bears lived. Many bears were hunted and killed. Now only 1,200 to 1,400 grizzly bears have remained. In and around Yellowstone National Park, grizzly bears have been making a comeback because of people's efforts to protect them. Some bears are moving to areas where people live. People are also moving into grizzly countries. People there have to learn how to live with their new, furry   neighbors peacefully. If someone leaves their barbecue grill out overnight, or leaves their pet food or rubbish where a bear can get it, the bear will learn to come to their house for food. Grizzly bears that learn to eat people's food can become dangerous, and they often have to be killed or moved. Also, it's important not to surprise a grizzly. Besides, if you are hiking in a grizzly country, you should go with others and make a noise to make bears hear your coming and get out of the way. You may not want to invite grizzly bears to your next neighborhood party, but with a little effort, grizzly bears and people can live together peacefully. Why does the number of grizzly bears get smaller, according to the text? A) Settlers' buildings break the balance of their living environment. B) Land for them to live on is limited and they are hunted in large numbers. C) Yellowstone National Park wants to control the number of them. D) Living closer to humans makes them die from serious diseases.
