That's what people often say when they talk about computers. For over a quarter of a century, scientists have been making better and better computers. Now a computer can do a lot of everyday jobs wonderfully. It is widely used in factories, hospitals, post offices and airports. A computer can report, decide and control in almost every field. Many computer scientists are now thinking of making the computer "think" like a man. With the help of a person, a computer can draw pictures, write music, talk with people, play chess, recognize voices, translate languages and so on. Perhaps computers will one day really think and feel. Do you think the people will be afraid when they find that the computer is too clever to listen to and serve the people? Question: The passage is written to   _   . - warn people of the danger of the computer - tell people about the computer - tell people about computer scientists - show how to use the computer
(A).
tell people about the computer

Read the following article and select the best answer. Article: Everyone agrees that it's necessary to reduce carbon emissions   around the world. There is less agreement over exactly how nations should go about achieving a more carbon - free planet. Thus, the environmental equivalent: cap - and - trade carbon emissions, or place a carbon tax on all users? With cap - and - trade programs, governments limit the level of carbon produced by an industry. Companies that hold their emissions below the _ can sell their remaining allowance on a carbon market, while companies that go beyond their limit must purchase credits on that market. Carbon taxes are more straightforward: a set tax rate is placed on the consumption of carbon with the idea that raising the price will encourage industries and individuals to consume less. At the moment, cap-and-trade has the upper hand, but doesn't defeat the tax just yet. Supporters of the tax argue that a cap - and - trade system would be too difficult to administer - and too easily gamed by industries looking to sidestep emissions caps. Cap-and-trade advocates contradict that like all other flat taxes, a carbon collection would relatively burden lower - income families, who spend a greater percentage of their income on energy than rich households. So which system will have a larger effect on carbon consumption? A 10% carbon tax might reduce the demand for carbon about 5 % or less, according to an analysis by the Carbon Tax Center, an environmental advocacy group. That may not be enough. Businesses and governments haven't figured out how the two competing systems can work together, but in the end, the world may need both. Question: The passage focuses on  _  . - programs of collecting taxes - systems of reducing carbon emissions - reasons for reducing carbon emissions - contradictions between the two systems
(A).
systems of reducing carbon emissions

Read the following article and select the best answer. Article: I chose to study in Madrid because I had a desire to learn Spanish. My first impressions of Madrid were incredible. It was before the New Year that I arrived in Madrid for the first time. While traveling to my Spanish friend's house in a taxi, I appreciated the buildings along the road which were different from those of my own country. There are an incredible number of restaurants and bars from all over the world. If you are really into sightseeing, I hope you have rechargeable batteries for your digital camera, because one week really isn't enough time to see everything here including a number of art, science, and historical museums as well as parks, buildings, and amazing landscapes. What I liked best about life in Madrid was the fact that if you were frustrated with schoolwork and wanted to have some fun, you can easily go out. The nightlife never seems to stop and the people are all very friendly. You can meet people and practice Spanish while having fun at the same time. What I liked least was the fact that many people smoked in the streets. Also, coming from the US, I was used to having a big breakfast every morning, but while living with an actual Spanish family, I wasn't really satisfied with the food in the morning. I think I have definitely become more independent since I came back from Spain. Living in a big city like Madrid ,I found that it is necessary to plan ahead and to make a schedule for future. There is so much to see, not just in the Spanish World, but in the European World as well. Question: The author went to Madrid to   _  . - visit his friend - go on a sightseeing tour - study Spanish - complete his trip around Europe
(A).


assistant: study Spanish
