When Babbage was working at Cambridge, a new idea occurred to him. He wanted to construct a calculating machine to work out the solutions（解法）to maths problems not only with correctness but also with a speed beyond the power of any human mind. His machine could solve problems involving（涉及）long rows of figures in one continuous operation（运算）.

    In 1822 Babbage exhibited his invention and won a prize from the government. After that, he immediately started to work on a larger machine designed to solve more difficult problems. Although he received some money left by his father, the money was not enough to support his design. He wrote to the government about his plan and was given ￡2500 to start with, a sum worth much more in those days than it is now.

    Babbage continued his work in London for four years. Then his health broke down, and he had to take a long holiday abroad. When he returned to London in 1828, he was at the end of his resources. Many bills remained unpaid. His chief assistant and co-workers quarreled with him and left with many expensive tools. For one year no work was done. During this period, Babbage, whose mind was always active, suddenly thought of a completely new idea for the machine. He rushed to meet the government officials to explain his new idea. But this time, they were unwilling to help him. For eight years, they refused to say whether they wanted the machine or not, and their final answer was “No.”

    From 1828 to 1839, Babbage held the position of professor at Cambridge very successfully. But his greatest work was the unfinished calculating machine which stood covered in dust in his house. It was the beginning of the modern computer.

60．The machine Babbage designed would solve difficult maths problems _________.

   A．in one operation with few mistakes

    B．in more than one operation without any mistakes

61．Babbage failed to continue his research work in 1828 mainly because _______.

   A．he was in poor health                B．he almost ran out of money

   C．his co-workers argued with him          D．he spent all his money on his bills

62．Babage explained his new idea to the government officials, expecting that _________.

   A．they would agree to his plan              B．they would pay for his new idea

   C．they would support him with money     D．they would exhibit his new design

63．From the passage, we can infer that __________.

    A．Babbage failed to be a famous scientist at Cambridge

    B．Babbage always had new ideas but gave them up easily

    C．Babbage always needed support from the government officials

    D．Babbage was the first designer of the modern computer

A severely handicapped teenager who cannot walk,talk or hold a paintbrush has won a place at Oxford to study fine art.

Hero Joy Nightingale,16,who communicates through hand movements,is to be given assistants to paint and sculpt on her behalf.Her mother Pauline Reid “translated for” her daughter during interviews for the place at Magdalen College.

The teenager is the most severely handicapped student ever to be granted a place at Oxford.She suffers from “locked-in syndrome”,a profound apraxia caused by brain damage that renders her body useless and her voice mute.

She is unlikely ever to be able to walk,feed or care for herself but,thanks to the efforts of her mother,she can communicate.When Hero was four,Pauline devised a complicated system of hand gestures that equate to the alphabet.

A spokesperson for Oxford said,“The university welcomes applications from students with disabilities.In cases where students are profoundly disabled,there may be many issues that need to be carefully addressed before an individual can take up a place,such as establishing how the student can best be taught and examined.”

Hero,who suffers almost daily epileptic fits and has a hole in her heart,has not attended school since she was six.She has been taught at home by her mother and father,the pro-vice chancellor of Kent University.

Peter Giles,her art tutor until last year,said she has a genuine talent for art.“She is ferociously gifted.We would sit together and her mother would grab her daughter’s hand and then we would begin work,”he said.

Together,they built several modern sculptures from plaster and metal.“The instructions would take a while to decipher.But eventually,they would come,and eventually make sense.”

Hero’s classes will be held at the Ruskin School of Drawing and Fine Art.

If you and your friends wish to share a secret, you can write it in code, and no one else will be able to read it. Codes are one way of writing in secret. Ciphers (密码) are another. In a code each word is written as a secret code word or code number. In a cipher each letter is changed.

Codes and ciphers have played an important role in the history of the world. Julius Caesar, the Roman ruler who defeated almost all the countries in Europe about 2, 000 years ago, used a cipher when he sent secret messages to his troops. During the American Revolution, George Washington's spies used a kind of code to send him information about the enemy before his military action. In World War Ⅱ, the Americans "broke", or figured out, Japan's most important naval codes and got enough information to destroy a powerful Japanese fleet(舰队).

Storekeepers use codes to mark their goods. The codes show how much was paid for the goods or when they were added to the stock. Businessmen use codes to hide plans from their business enemies. Sometimes personal letters or diaries are written in code. Many people enjoy figuring out codes and ciphers simply as a hobby.

In the 16th century, codes and ciphers were very popular among scientists. They wrote messages to each other in code so that no one else would learn their secrets. Geronimo Gardano, an Italian astrologer(占星家), mathematician, and doctor, invented the trellis cipher. He took two sheets of paper and cut exactly the same holes in each one. Then he sent one sheet, which he called a trellis, to a friend and kept the other for himself. Whenever he wanted to write a message, he put his trellis over a clean sheet of paper and wrote the secret message through the holes. Then he removed the trellis and filled the rest of the paper with words that would make sense. When his friend received it, he put his trellis over the writing and read the secret message.

What does the underlined word "trellis"mean?

A. A piece of paper with many small holes.          B. A machine with a lot of small holes.

C. A letter with unreadable words and sentences.   

D. A sheet of paper with groups of Arabic figures.

Which of the following statements is true?

A. Ciphers can be broken or figured out more easily than codes.

B. You could read some words in Geronimo' s letter without his trellis.

C. The first person who ever used a cipher in history was Julius Caesar.

D. Fondness of using codes was the hobby of the scientists in the 16th century.

The best title of this passage is________.

A. Codes and Ciphers                  B. Differences between Codes and Ciphers

C. History of Codes and Ciphers         D. Inventors of Codes and Ciphers

KATHMANDU, Nepal (CNN) - Nepal has given its security personnel permission to shoot pro-Tibet demonstrators during China's Olympic flame climb to Mount Everest's summit early next month.

"About 25 soldiers and policemen have established camps on the mountain and they have been ordered to use force if necessary to stop any anti-Chinese activities," Mod Raj Dotel, spokesman for the home ministry, said Sunday. "This could mean shooting if necessary."

Security personnel will also check mountain climbers for non-essential expedition materials, Dotel added.

"If anyone is found with anti-Chinese material their permit will be canceled and returned from the mountain," he said.

Chinese climbers plan to take the Olympic flame to the top of the world's highest peak, at 8,848 meters (29,028 feet) as part of the global relay leading up to the August 8 opening of the Summer Olympics in Beijing.

Spring is the most popular season for climbing Mount Everest, which straddles(跨越) the border between Nepal and Tibet, an autonomous region of China.

The Nepali government has given permits to dozens of climbers from 30 expeditions this season.

But between May 1 and May 10, climbers are barred from going above 6,400 meters until the torch run is completed. China plans to take the Olympic flame to the summit sometime then.

Bad weather conditions allow only about two opportunities in May for a push to the summit.

The Chinese have not allowed any expedition to climb the mountain from the north side, according the Kathmandu representative of the Tibet China Mountaineering Association.

Almost every day in the past month, Nepalese police have arrested pro-Tibet protesters from in front of the Chinese Embassy and the United Nations offices. The demonstrators are released later in the evening.  

Supporters of Tibet punish the government's attitude toward the autonomous region, and many believe China should not have been awarded the honor of hosting the Olympic Games.

Earlier torch relay stops in London, England; Paris, France; and San Francisco, California attracted tens of thousands of demonstrators. They led to attacks on the torch and relay participants, and prompted police to make dozens of arrests.

Subsequent stops in Argentina, Tanzania and Oman were trouble-free.

In Pakistan, authorities closed the relay to the public. And India shortened the relay and kept thousands of anti-Chinese protesters at bay by sealing off roads and shuttering buildings along the route.

The relay went smoothly in Bangkok, Thailand, on Saturday, amid heavy security and scattered protests along the route.

The flame arrived in Malaysia on Sunday. About 1,000 police officers will be on hand to watch for protesters during a relay in the capital city Kuala Lampur Monday.

61．When will China's Olympic flame probably reach Mount Everest's summit?

A．April 28     B．May 12        C．June 10        D．May 7

62．The underlined word “barred” means_____________.

A．permitted      B．stopped        C．encouraged     D．introduced 

63．How many times Climbers can reach the top of the mountain at most in May?

A．once             B．twice   

C．three times            D．as many times as they can

64．Where did the torch relay meet no trouble?

A．India          B．Nepal     C．Tanzania         D．France

65．What is the attitude of the Nepali government towards towards China's Olympic flame climb to Mount Everest's summit?
