WELLINGTON, New Zealand (AP) ---- About 140 pilot whales that stranded(使...搁浅) themselves on a remote stretch of New Zealand beach have died, but conservation workers and volunteers are hoping the remaining 60 or so will survive after they managed to get them refloated, an official said Saturday.

The geography of Farewell Spit on the South Island seems to work against whales, which regularly become stranded there. The stranding of 198 whales on Friday was one of the largest in recent years and inspired 80 workers and volunteers to help out.

By late Saturday, 140 of the whales had died, said Department of Conservation area manager Andrew Lamason.

He said the workers and volunteers worked throughout the day to keep the surviving whales watered and covered before refloating them during Saturday night’s high tide.

“We’ve had a really good crew of volunteers, and people have been wanting to come from all over the country,” Lamason said.

He said the surviving whales had moved to deeper water. But he cautioned that although hopes for their survival were high, whales had been refloated in the past only to return and get stranded again.

Lamason said the scale(规模) of the stranding has been tough on the helpers, both physically and mentally.

“It’s very sad, they’re very intelligent animals,” he said. “The common view is that it’s part of nature.”

The focus will now turn to the dead whales, and the enormous task of dealing with the remains, Lamason said, adding that in the past helpers have typically buried them in the sand, but that he’s not sure what the approach will be this time.

He said the department had been experimenting with moving the the dead whales into the water, which has the advantage of providing food for other sea creatures.

3.Which of the following words can be used to describe Lamason’s attitude towards the result of refloating the whales?

A. Doubtful. B. Optimistic.

C. Positive. D. Careless.

4.What did Lamason say about the feelings of the workers and volunteers?

A. They were very happy to see so many whales.

B. They thought refloating the whales was not a hard job.

People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.

In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. “Today we’re looking at science fiction becoming tomorrow's reality-the driverless car. ” The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.

Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America. “A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. ” Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don’t replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.

“By taking out drivers, you also remove most risks of an accident, ”Kendall said. He said , “Consumers, however, may be unwilling to lose control. It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. ”

Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.
