25、Complete the following passage by using the words in the box. Each word can only be used once. Note that is one word more than you need.

Think you can walk, rive, take phone calls, email and listen to music at the same time? Well, New York’s new law says you can’t. and you I’ll be  1  $100 if you do it on a New York City street.

The law went into force last year, following recent research and a (n)  2  number of accidents that involved people using electronic devices when crossing the street.

Who’s to  3  ? scientists say that our multitasking(处理多重任务的)abilities are limited.

“We are under the impression that our brain can do more than it often can ,” says Rene Marois, a scientist in Tennessee. “But a major limitation is the inability to  4  on two things at once.”

The young are often considered the great multitaskers. However, an Oxford University research suggests this idea is open to question. A group of 18-to 21-year-olds and a group of 35-to 39-year-olds were given 90 seconds to translate  5  into numbers, using a simple code. The younger group did 10 percent better when not interrupted. But when both groups were interrupted by a phone cal or a (n)   6  message, the older group matched the younger group in speed and  7  .

It is difficult to measure the productivity lost by multitaskers. But it is probably a lot. It is estimated that the cost o interruptions to the American economy is nearly $650 lillion a year.

The   8  is based on surveys with office workers. The surveys conclude that 28 percent of the workers’ time was spent on interruptions and   9  time before they returned to their main tasks.

 

 

22、The spectacular Victoria Falls links two countries, Zimbabwe and Zambia.It was discovered by David Livingstone in November 1855 and is known in the local language, as Mosi-oa-tunya, “the smoke that thunders”.It was Livingstone who named Victoria Falls after his Queen and stated in his own famous diary entry--- “Angels in their flight must have gazed.”

Adventure sports and a range of accommodation

The rustic(乡村的)Victoria Fall town--- just ten minutes from the Fall, and on the outskirts of the Zambezi National Park--- has all facilities necessary to act as a base for exploring the region.Accommodation is plentiful--- from low budget campsites to luxury hotels.

And across the border in Livingstone, Zambia, visitors will find a town suitable for the adventure sports enthusiasts with lots of travel and adventure sports companies.

Victoria Bridge--- the third highest Bungee jump in the world

At a height of 364 feet, the Victoria Falls Bridge, completed in 1905, is the world’s third highest Bungee jump, though the scream factor is arguably the loudest, making it a great draw-card for adventure sports enthusiasts.While dropping into the abyss (深渊), you will be blasted with spray from the thundering Victoria Falls, and then jerked (猛烈) back to reality within inches of the swirling eddies (漩涡) of the Zambezi below.

How to enjoy the Victoria Falls Experience--- take to the sky’s and the water

Anyone can pay an entrance fee and walk around the ridge of Victoria Falls and take some good pictures to send home, but to truly experience the size and scope of the spray, you’ve got to get airborne, and there are options--- tame and a little wild: fixed wing planes, helicopters, microlights.

River Rafting, in many shapes and sizes, is conducted on both sides of the Zambezi River, in Zimbabwe and Zambia below Victoria Falls.
