Worries about Internet Use

1. A recent survey into Internet use has thrown up some worrying results. The Stanford University survey asked respondents to answer a number of questions about their Internet use. It asked how much time they spent on the Internet and whether Internet use had affected the amount of time they spent with family and friends.

2. The answers were interesting but not unexpected. Two-thirds of the people surveyed responded that they still spend fewer than five hours a week on the Internet. The survey concludes that the behaviour of these people has changed little. However, a quarter of those people who use the Internet for more than five hours a week claimed that they spend less time with their family and friends.

3. Professor of Political Science at Stanford, Norman Nie, tells us that we are moving from a world where we know and see neighbours and friends to one where interaction takes place at a distance. It seems that the results of the survey prove that the Internet is turning people into solitary beings who can’t be bothered to call their mother on her birthday.

XI. Answer the following questions:

1. What survey did the Stanford University carry out?

2. What results were achieved?

3. What are the worries about Internet use?

4. Why do people feel lonelier today than they used to?

5. How much time do you spend surfing the Internet? Is there anything that you want to change?

XII. Translate passage 1 into Russian.

XIII. Read the text. Explain what uav is. Describe its structure and working principles. Mit Makes a Drone Aircraft that Can Fly Indoors

1. We have seen quadrocopters do some pretty awesome indoors maneuvers, from swarming to playing a piano symphony. But what we really want to see is a full-fledged airplane whipping around the inside of a building.

2. MIT’s Robotics Group is taking steps toward making this a reality with an autonomous UAV (unmanned aerial vehicle) that can fly around in a tight car park. To accomplish this feat, the MIT scientists developed a short winged, laser-equipped brainiac UAV that can understand where it is and how to avoid obstacles all on its own.

3. MIT professor Mark Drela developed the UAV with a short 2-meter wingspan so that it could maneuver quickly in enclosed spaces. More importantly, the small airframe packs the same computational power as a netbook, with an Intel Atom processor inside.

4. It needs all this processing power to run a state-estimation algorithm in conjunction with a set of lasers, accelerometers, and gyroscopes. With these combined technologies, the UAV is able to figure out its own orientation and velocity as well as 15 other in-flight factors without a GPS signal. At the same time, the UAV constantly runs an algorithm that it uses to avoid obstacles it comes across on the fly.

5. So far, the MIT scientists have run a preliminary test of the system aided by a preloaded map. The UAV successfully flew for a total of three miles at 22 miles per hour.

6. The MIT researchers’ next step will be to build an algorithm that allows their UAV to make a map of its surroundings on the fly.
