单选题 The year 2000 will bring big changes in communication. Cell phones will be small enough to carry in your pocket. Videophones will let you see the person you are talking to on the phone. Tiny hand size computers will know your favorite subjects. The Internet and email will be everywhere. Technologists believe 2000 will be the year of video messaging. You will be able to see whom you're talking to. Also in the near future small wireless boxes will pick up information from satellites. In 5 years, computers won't need to be connected through wires. All of this will be good for rural areas and countries that don't have cable or telephone now. In 20 years you may only need to think about something and the computer will do it. Constance Hale is the author of Sin and Syntax, 'I believe that email has been an incredible boon to communication. People are writing today where they would have been telephoning yesterday. So people are engaging with words more than they have for the last couple generations.' If people use email and the Internet more, it could make people better readers and writers. Some people think the most important part of communication is to make people understand each other better. Will technology make that easier? The translator also comes in handy in medical emergencies. Tam Dinh says, 'where people are injured it's always important to get as much information as quickly as possible.' Bob Parks is an Associate Editor of Wired Magazine, 'Bob's morning begins at about 6:45 am. and Bob is kind of mad, because Bob usually gets up at around 7:15 and likes to cut it close with his morning commute, but I look at my radio and it says that there's a traffic jam on 101 South and I'm gonna need an extra 1/2 hour. And so my radio has got a net connection, wireless net connection as well as a good old power cord to the wall and it has received notice that there's a traffic jam and it has calculated an extra 1/2 hour commute time.' Some day everything may be connected to the Internet. Your refrigerator will add milk to your Internet grocery list when the date on the carton has passed. Light bulbs will be ordered before they burn out. It's fun to try to guess the future. Usually the predictions are wrong. The one thing we know for sure is that we can't imagine how technology will change.

单选题 'Do you ______ a drink?' asked the man of the woman.

单选题 There are millions of left-handed people in the world. A number of them got together in 1975 to form an association called Lefthanders International. The purpose of the organization is to fight discrimination(particularly in jobs)and to inform the public. They want everybody to understand the left-handers are neither 'strange' nor sick nor dangerous. Many studies have been made recently about hand preference in humans. They have brought interesting results. It has been found, for instance, that many more men than women are left-handed; that all children use both hands about equally until they are three years old; and that hand preference is not clearly marked until age six. Above that age, most people not only favour one particular hand but also have a favourite eye, a favourite ear and foot. We know that the left side of the body is controlled by the right side of the brain, which seems that this particular half is the seat of emotions, imagination, and of the sense of space. And, indeed, lefties seem to be more creative than the right-handers; they also seem to be more athletic and to do better in some professions which—like sports—require a good sense of space. In a large school of architecture, it was found in 1977 that 29% of the professors and 23% of the graduating students were left-handed— while lefties represent less than 10% of the general population. Finally, left-handers may be more stubborn and more impulsive (冲动的) than right-handers. And they are more likely to suffer from problems such as stuttering(口吃) and a difficulty in reading called dyslexia. The problems are more serious in left-handed persons who have been forced to favour their right hand. Doctors insist that one should never try to change a child's hand preference.
