题目列表(包括答案和解析)

Stepping into a pool of water is common enough, but who could ever imagine stepping into a pool of fish? In February of 1974, Bill Tapp, an Australian farmer, saw a rain of fish that covered his farm. How surprised he must have been when he heard many fish hitting against his roof!

   What caused this strange occurrence? This is a question that had long puzzled people who study fish. The answer turned out to be a combination of wind and storm.

  When it is spring in the northern part of the world, it is fall in Australia. Throughout the autumn season, terrible storms arise and rains flood the land. The strong winds sweep over Australia like huge vacuum cleaners, collecting seaweed, pieces of wood, and even schools of fish. Strong winds may carry these bits of nature for many miles before dropping them on fields, houses, and astonished people.

  Although they seem unusual, fish-falls occur quite frequently in Australia. When Bill Tapp was asked to describe the scene of fish, he remarked, “They look like millions of dead birds falling down.” His statement is not surprising. The wonders of the natural world are as common as rain. Nature, with its infinite wonders, can create waterfalls that flow upward and fish that fall out of the sky.

  56. What is this passage about?

  A. A sad story.             B. A rain of fish.

  C. Australia’s northern part.     D. The damage done by floods.

  57. Fish-falls occur in Australia_________ .

  A. quite often       B. on large farms

  C. only in winter     D. when the air is calm

  58. It is a known fact that ________.

  A. one should watch where one steps

  B. Bill Tapp is a scientist who studies farming

  C. the natural world can never create waterfalls that fall upward

  D. the seasons in the southern part are different from those in the northern part

  59. The word “infinite” is closest in meaning to _________.

  A. easy    B. difficult    C. countless    D. dangerous

  Since the 1970s, scientists have been searching for ways to link the brain with computers.Brain-computer interface(界面)(BCI)technology could help people with disabilities send commands to machines.

  Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic school in Lausanne, Switzerland, demonstrated(展示)a small robotic wheelchair directed by a person's thoughts.

  In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand.He could even talk as he watched the vehicle and guided it with his thoughts.

  "our brain has billions of nerve cells.These send signals through the spinal cord(脊髓)to the muscles to give us the ability to move.But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles," Tavella says."Our system allows disabled people to communicate with external world and also to control devices."

  The researchers designed a special cap for the user.This head cover picks up the signals from the scalp(头皮)and sends them to a computer.The computer interprets the signals and commands the motorized wheelchair.The wheelchair also has two cameras that identify objects in its path.They help the computer react to commands from the brain.

  Prof.Milan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands."The practical possibilities that BCI technology offers to disabled people can be grouped in two categories:communication, and controlling devices.One example is this wheelchair."

  He says his team has set two goals.One is testing with real patients, so as to prove that this is a technology they can benefit from.And the other is to guarantee that they can use the technology over long periods of time.

(1)

[  ]

A.

help to update computer systems

B.

link the human brain with computers

C.

help the disabled to recover

D.

control a person's thoughts

(2)

How" did Tavella operate the wheelchair in the laboratory?

[  ]

A.

By controlling his muscles.

B.

By talking to the machine.

C.

By moving his hand.

D.

By using his mind.

(3)

Which of the following shows the path of the signals described in Paragraph 5?

[  ]

A.

scalp→computer→cap→wheelchair

B.

computer→cap→scalp→wheelchair

C.

scalp→cap→computer→wheelchair

D.

cap→computer→scalp→wheelchair

(4)

The team will test with real patients to

[  ]

A.

make profits from them

B.

prove the technology useful to them

C.

make them live longer

D.

learn about their physical condition

(5)

Which of the following would be the best title for the text?

[  ]

A.

Switzerland, the BCI Research Center

B.

New Findings About How the Human Brain Works

C.

BCI Could Mean More Freedom for the Disabled
