Question: Read the article and select the best answer. Article: What's your dream vacation? Watching wildlife in Kenya? Boating down the Amazon? Sunbathing in Malaysia? New chances are opening up all the time to explore the world. So we visit travel agents, compare packages and prices, and pay our money. We know what our vacation costs us. But do we know what it might cost someone else? It's true that many poorer countries now depend on tourism for foreign income. Unfortunately, though, tourism often harms the local people more than it helps them. It might cost their homes and lands. In Myanmar, 5,200 people were forced to leave their homes among the pagodas in Bagan so that tourists could visit the pagodas. Tourism might also cost the local people their livelihood and dignity. Local workers often find only menial jobs in the tourist industry. And most of the profits do not help the local economy. Instead, profits return to the tour operators in wealthier countries, When the Maasai people in Tanzania were driven from their lands, some moved to city slums. Others now make a little money selling souvenirs or posing for photos. Problems like these were observed more than 20 years ago. But now some non-government organizations, tour operators and local governments are working together to begin correcting them. Tourists, too, are putting on the pressure. The result is responsible tourism, or "ethical tourism." Ethical tourism has people at its heart. New international agreements and codes of conduct can help protect the people's lands, homes, economies and cultures. The beginnings are small, though, and the problems are complex. But take heart. The good news is that everyone, including us, can play a part to help the local people in the places we visit. Tour operators and companies can help by making sure that local people work in good conditions and earn reasonable wages. They can make it a point to use only locally owned hotel, restaurants and guide services. They can share profits fairly to help the local economy. And they can involve the local people in planning and... Question: What is probably the best title for the article? Options: A: Tourism Causes Bad Effects. B: Tourism Calls for Good Behavior. C: Vacations Bring a Lot of Fun. D: Vacations Cost More Than You Think
Answer: D

Question: Read the article and select the best answer. Article: The TV science-fiction seriesStar Trekno longer looked far-fetched as four men and four women in black space-suits locked themselves into a giant hi-tech greenhouse, known as a 'biosphere', in the Arizona desert yesterday for a two-year study of the environment. As dawn broke over the Santa Catalina mountains, the eight waved goodbye to television cameras. Edward Ross, their multibillionaire sponsor from a Texas oil family, closed the door of the $150 million structure, with its mini-ocean, marsh, desert, savanna, rain-forest and 3,800 plant and animal species designed to allow the team to recreate Earth and its ecosystems. The so-called Biosphere 2 is the latest of a dozen environmental projects started by the self-titled 'ecopreneur'. The project's main aim is to set up a self-sustaining community for possible use in a spaceship or on another planet. The crew members must plant, harvest and process their food on a half-acre farm in the seven-storey glass and metal structure, while conducting a series of experiments. 'We will be custodians of our new little world,' said Abigail Mayer, aged 31, a US marine biologist on the team, her voice choking with emotion. 'It is a brave new step.' Many scientists, however, are more than skeptical. They point out that the largest closed ecosystem which survived more than a few days was smaller than a football. It was developed at the University of Miami and contained only shrimp, algae and other micro-organisms. Critics have also accused Mr. Ross of being more interested in producing a profitable theme park than in carrying out serious scientific research. Hundreds of tourists visited the site daily in the summer before it was occupied by the team. They paid $9.95 to enter and all stopped at the souvenir shop. Question: What can we infer from the passage? Options: A: There is a scene in Star Trekwhere four men and four women locked themselves into giant greenhouse. B: All the species of plants and animals on the Earth were brought into the greenhouse. C: Mr. Ross made tourists stop at the souvenir shop to gain profits. D: Many scientists are doubtful whether this system can last long enough.
Answer: D

Question: Read the article and select the best answer. Article: There are some great differences between the traditional family and the modern family. The first important difference is in the man's role.The traditional husband was the head of the household because he was the only one who worked outside the home.If the wife worked for money,then the husband was not considered to be a good provider,In many families today,both husband and wife work for money.Therefore,they share the role of head of household.In addition,the traditional husband usually made big decisions about spending money.However,the modern husband shares these decisions with his working wife.Also,the traditional husband did not help his wife with housework or meal preparation. Dinner was ready when he came home,In contrast,the modern husband helps his working wife at home.He may do some of the household chores,and it is not unusual for him to cook. The second difference is in the woman's role. In the traditional family,the woman may have worked for miney during her first years of marriage.However,when she gave birth,she would usually give up her job. Her primary role would be to take care of her family and home.In contrast,in many families today,the modern woman works outside the home even after she has children .She's doing two jobs instead of one,so she is busier than the traditional mother was.The traditional wife learned to live within her husband's income.But the modern wife does not have to because the family has two incomes. The final difference is in the role of the children .In the traditional family,the children were taken care of by the mother because she didn't work outside.However,today pre-school children may go to a child-care center or to a baby-sitter regularly because the mother works.The school-age children of a traditional family were more dependent.Their mother was there to help them get ready for school and to make their breakfast.In conrtast,modern children are more independent.They have to get up early and get ready for school themselves,and they may even have to make their own breakfast.
