[单选题]Text 1 When I started my careef I was astonished by how superhuman some Fortune 500 executives were.It seemed they were magicians.Every decision they made based on deep market knowledge and up-to-date information.How did they do it?Thcy have marketing teams that can pull research together in hours.They have chiefs of staff who give them carefully crafied agendas for every day.These teams give Fortune 500 executives what appears to bc super-human knowledge.Foriunately for those of us who don't have Fortune 500 budgets at our disposal,it's getting easier and casier to build your own secret support staff.Within five years,most executives at any size company-and,indeed,most knowledge workers-will have tools that do much of the work of a CEO's private group.That is,"Cyborg systems,"or what I called"agents".It will make this possible,using a blend of learning algorithms and distributed labor to perform an ever-widening range of tasks at low cost.With help from these agents,we'II be able to look as smari as those CEOs do today.I got one taste of this when I started using Wonder.Wonder is like having a personal researcher,deploying a small army of experts,including trained librarians,to do small,defined research projects for me.I ask Wonder for help.For$30 to$60,Wonder saves me hours every week.More and more products and services will fuse machine intelligence with crowd work to help users get things done.To be clear,CEO support teams aren't going away.Top executives will continue to see benefits from dedicated,trusted support staff who can handle difficult,urgent,delicate work.But machine intelligence systems can take on elements of what these people do at a much lower cost,democratizing many of these capabilities.Granted,there is going to be a lot of garbage before we realize the full promise of these virtual support armies.Many ofthem fail to live up to even basic promises,like this weather bot that has trouble telling you about the weather.But if you can filter through the many new offerings to fmd valuable tools,your work will improve and you may even start to look like those CEOs with the seemingly.
Executives in small-size companies can work as Fortune 500 CEOs by_____.
A.hiring more knowledge workers
B.depending on supporting staff
C.getting lower cost labor
D.using machine intelligence

[单项选择]
In a world where bad news has become everyday news, people are turning to an ancient technique to deal with stress: meditation. At meditation centers, prayer groups and yoga studios around the United States, more and more are finding peace of mind by being quiet. Some use meditation to help deal with life changes; others, to process the painful reality of political and social unrest around the world of the type that has been experienced more recently. Stress from the September 11 terrorist attacks is probably "about 70 percent" of the reason one Chicago man started meditating and practicing yoga with his new wife. He became so emotionally affected that he realized he needed help in managing his stress. The yoga classes he takes begin and end with meditation. This "quiet time" helps him feel a lot more relaxed and gives him more breath control. The fact is, though, that he is not alone.

A. coping with growing stresses.
B. seeking refuge from social unrest.
C. escaping painful experiences.
D. maintaining emotional health.

[单项选择]The world seems to be going diet crazy, and yet our nation’s obesity rate has shot up year after year. And, it’s not only the over 20 population that has to worry about their weight anymore.

According to the website cosmiverse.com, 11% of adolescents are categorized as being over-weight, and another 16% are in danger of becoming overweight. This is a 60% jump from the 1980’s.

This new take on education has left us with physical activity at an all-time national low, resulting in obesity and poor physical conditioning at an all-time national high. The schools have tried a few solutions; the most recent in the news has been taking soda out of schools and increasing the required time children must be active during schoo
