单选题. Scientists are building the world's first thinking robot. It's true. Some say machines that walk, speak and feel will have been made by 2020. Kismet is the name of a robot which scientists have built this year at the Massachusetts Institute of Technology (MIT). Kismet is different from traditional robots because it can show human emotions. Kismet is one of the first robots of a new generation that look like human beings and can imitate human feelings. Some people say that by 2020 we will have created robots with brains similar to those of adult human beings. They will be doing dangerous jobs as well as more and more of the household work for us. In Japan, scientists are designing robots that will entertain people by dancing and playing the piano. Meanwhile, people who worry about the future are wondering whether robots will become monsters. Will people themselves become increasingly like robots? Experts predict that more and more people will be wearing micro-computers connected to the Internet in the future. People will have microchips in various parts of their body, which will connect them to a wide variety of small machines. Perhaps we should not exaggerate (夸大) the importance of technology, but one may wonder whether, in years to come, we will be falling in love, and whether we will feel pain. Who knows?1. Kismet is different from traditional robots because ______.

单选题. A house is the most expensive thing most people will ever buy. Very few people have enough money of their own to buy a home, so they have to borrow money from a bank. Borrowing money from a bank to buy a house is called "take a mortgage (抵押)." The bank usually lends money or gives a mortgage for twenty-five years. Houses are so expensive that many people nowadays have to borrow as much as $50,000. In other words, they will have a $50,000 mortgage. How can you get a mortgage? When you find a house you like, you go to a bank. The bank will research your financial (金融的) history and decide if they think you are a good risk. They will want to know what kind of job you have, what kind of salary you make, and how long you have had the job. They will also want to know how much money you have. In addition, the banks will require a down payment. Depending on which state you live in, the bank may require as much as 30% of the price of the house as a down payment. The bank will then lend you the rest of the money to buy the house. Many people are never able to buy a house because they cannot save enough money for the down payment.1. What does a house mean in the United States?

单选题. The worst recession since World War n took place on the high street, with one in ten stores left empty as wounded retailers went to the wall (破产). But as the recovery gets under way and empty shops find new tenants, the names over the doors are changing. Several foreign retailers have plans to set up shops in the UK this year, attracted by the scale of the market and a national obsession with shopping. After falling through much in 2009, retail spending starts to recover at the turn of the year and with so many shops empty, landlords are offering prospective tenants the best deals in years. Lorna Hall, retail editor at a trend forecaster center, says that even before the credit crunch (艰难局面) some big American groups were grading the UK. Stores such as Abercrombie Fitch and Best Buy have been hit by the downturn on Main Street but have been determined to press ahead with expansion in the UK, if only to gain a foothold (立足点) for their large online businesses.1. One of the consequences the recession caused is that ______.

单选题. A British study found that B vitamins could reduce brain shrinkage in older people with mild memory loss. It showed that B vitamins caused an average one-third reduction in brain shrinkage among adults who had troubles remembering. Retired Oxford University pharmacology (药理学) professor David Smith was a leader of the study. He praised the use of the vitamins as simple and safe. He also said researchers didn't yet know if B vitamins could prevent or slow Alzheimer's disease (老年痴呆症). Vitamins are important for good health. These complex organic substances help to carry out chemical changes within cells. If we do not get enough of the vitamins we need in our food, we are at risk of developing a number of diseases. Some shrinkage of the brain is thought to happen normally as people grow older. Yet studies have shown a link between a larger shrinkage and Alzheimer's disease. The Oxford researchers say about one in six people over age seventy has problems with mental operations. They say half of these people develop serious loss of mental ability, as in Alzheimer's disease. Over time, the disease robs people of their memories. Finally, it takes away their ability to care for themselves.1. According to the British study, B vitamins could help people who had troubles in ______.
单选题. A carefree summer vacation can be yours with these tips. 1. Fly into Alternate Airports Most major destinations are served by more than one airport. Flying into a less popular one can result in cheap tickets. Another added perk of quieter airports? Shorter check-in and security lines, and less waiting around. 2. Use public transportation for city travel to save time and money When possible, take public transportation from the airport to your hotel. For example, the London-Heathrow express train takes just 15 minutes to get from airport to city and costs under 20 pounds. By contrast, "A taxi costs about 70 pounds and takes 40 minutes," reports DiScale. 3. Eat smart, explore and save Look for ways to take your order in a pricey restaurant and you can avoid "Are we about to run out of money? Don't order an appetizer. Don't drink a lot of booze," says DiScale. Also, cover more ground by spreading out your snack places. "Have dessert at a café or ice cream stand, instead of at the dinner restaurant," suggests DiScale. You'll see more of the city and decisions about where to go for dinner will be less worrying. 4. Hit the market Much like reading the local newspaper, visiting a market gives context to a foreign country. Even the smallest village tends to have a weekly open-air market (often on Saturday mornings), while in larger towns and cities, expect additional market days, as well as big markets. Markets also sell amazing, wallet-friendly souvenirs. Think about sea salt, local spices or sauces, and regional oils and vinegars. Eatable gifts are almost always appreciated, saving you the stress of finding the "perfect" gift for each person on your list.1. The passage aims to tell the reader how to ______.
