If it looks like a fish and swims like a fish, it usually is a fish. But not the new, lifelike robot fish developed by UK scientists, which have been swimming around the London Aquarium(水族馆) as they wait for their release off northern Spain in 2011.

Equipped with tiny chemical sensors(传感器),the fish will collect data on pollution in the port of Gijón and wirelessly send the information back to the control center.

“It’s a little lab onboard the fish,” said Rory Doyle, a scientist at BMT Group. The robots were designed, and are being built, by professor Huosheng Hu and his team at the University of Essex, UK.

The sensors will search for dangers such as chemical waste and will allow officials to map in real time the sources and effects of pollution, Doyle said. w_w w. k#s5_u.c o*m

He and his colleagues chose a fish design because hundreds of millions of years of evolution(进化) has created an energy-efficient creature, he said. “Nature has done it very, very well.” But copying such a successful design comes at a cost: nearly 29,000 u.s. dollars per robot. m

The fish, therefore, will be built “robust” enough to handle any possibilities, Doyle said. They can’t get caught in nets easily, for instance, and the tracking systems inside can help the robot fish avoid crashes with boats and other things in the way.

So far, it also seems unlikely the robot fish will be mistaken: At the London Aquarium, sharks swim away from the fake fish, possibly because they find the robots electromagnetic fields(电磁场) unpleasant, Doyle said. w_w w. k#s5_u.c o*m

At the same time, scientists are working to ensure that the sounds of the robots and other factors don’t disturb the natural environment, he added.

The robot fish was developed in order to_______. w. k#s5_u.c o*m

A.be displayed on a robot exhibition in Spain

B.be sent to London Aquarium as a gift

C.get information of ocean pollution

D.collect data on the fishes in deep sea

According to Doyle, the robot was designed into fish shape in order to_______.

A.cut the cost of the robot

B.make the robot beautiful

C.reduce the sounds of the robot

D.make the robot work better with less energy

We can infer from the passage that the robot fish______. k#s5_u.c o*m

A.would send pictures of sea life back

B.would not be looked on as a real fish by fishes

C.could swim much faster than fishes like sharks

D.could help find new forms of energy in the sea

The underlined word “robust” in Paragraph 6 probably means_____.

A.small and light    B.big and heavy

C.smooth and soft    D.strong and smart

The house was quiet at 5 am and Tim' s mother was asleep. Only the sound of the big freezer broke the quiet. He’d dreamt of the cave last night. The purring (轻微颤动声) of the freezer had been the sea.

Tim pulled on a sweater and put some apples into his schoolbag. It was too early for breakfast. He'd eat after he’d been through the cave, sitting on the rocks and staring at the sea.

He wished he had a proper pack. His schoolbag would have to do. What else? Sandwiches---but his mother might wake up if he started pulling out bread for sandwiches, she' d want to know why he had to leave so early. He settled for some biscuits, and left a note stuck to the table:

Gone to Michael’s. Back tonight, Tim.

The sky was high and soft and light outside, though the sun still wasn't up. Even the highway up the hill was quiet as he made his way down the street. The wind from the sea was fresh and sweet.

The sandhills still breathed heat from yesterday’s sun, though the top of the sand was cool. He ran down to the beach impatiently, but there was no one, just dry sand dancing in the early wind and seabirds marching up and down watching the waves. O%

The light changed suddenly. The first rays of sunlight stretched (延伸) across the sea. The sun was pushing its way over the edge of the world.

Over the first rocks, along to the point. Tim glanced back. The beach was still empty. The sun sailed higher in the sky.

He could see the cave now, even darker in the morning light. The sand turned silver then dark gold as the water flowed away from it. He had to force himself to go closer. Why was it so much more mysterious (神秘的) now? But it would be silly to go back now after so much trouble. He needn't go in all the way. . .

63. What did Tim do at the beginning of the story?

A. He left the house quietly.      B. He had breakfast at home.

C. He left a note on the freezer.  D. He put a sweater in his schoolbag.

64. "He settled for some biscuits” ( in Paragraph 3 ) means that Tim_______.

A. had to leave the biscuits on the table         B. liked biscuits better than sandwiches

C. had to take biscuits instead of sandwiches  

D. could only find some biscuits in the kitchen

65. What made it possible for Tim to see the entry to the cave?

A. The height of the first rocks.                 B. The ups and downs of the waves.

C. The change in the position of the sun.     D. The vast stretch of the sunlit beach.

66. In the story, Tim's mood (心情) changed from_________.

A. loneliness to craziness                         B. anxiousness to excitement

C. helplessness to happiness                      D. eagerness to nervousness
