The idea for the Internet began in the early 1960s in the United States. The Department of Defense wanted to connect their computers together in order to share private information. In 1969, the ARPA net (an early form of the Internet) first connected computers at four American universities. One computer successfully sent information to another. In 1972, scientists shared ARPA net with the world. They created a way to send person-to-person messages using ARPA net.

　　Somehow Rey had managed to struggle free from the rope around his neck, after being left to die a slow death as punishment for being a bad Spanish greyhound.

　　It is believed that 50,000 greyhounds are killed by their

　　owners in Spain each year after they grow too old, or turn out to be too slow to hunt with. Dogs have also been found thrown into wells, burnt alive and even injected with poison. But Rey's intended fate was, even within the levels of cruelty usually shown to Spanish hunting dogs, especially cruel. The rope around his neck had been set at a height so that his front paws could not touch the ground, meaning that he was intended to stand on his back legs until he was too tired to support himself. When his legs finally became too tired, the rope should have done its work.

　　“They call it the typewriting death, because the dog's back legs struggled against the ground and make the clicking sound of a typewriter，” said Albert Sorde, of the SOS Galgos greyhound rescue group. “It is a punishment for greyhounds that are thought to have made their owners lose face. ”

　　“Rey's throat was severely damaged but we managed to find a vet to operate and, though it was expensive, he survived，” he said.

　　Greyhounds in Spain are used for hunting hares.“The dogs are meant to imitate the swerves (轉向)of the hares，” said Sorde. “Those who don't, and make their owners look bad, are called dirty greyhounds' and are most likely to be killed by the typewriter method. ”

　　16. Rey was intended to be killed by________.

　　A. kicking

　　B. burying

　　C. hanging

　　D. drowning 答案與解析：C　hang在這里是“絞刑”的意思，文中第三段提到“勒住Rey脖子的繩子”。因此選擇C項。 17. The underlined word“ vet” ( in Paragraph 5 )probably means“________”．

　　A. animal doctor

　　B. ambulance

　　C. animal medicine

　　D. equipment 答案與解析：A　給動物處理傷口的職業，只有“獸醫”最合適。 18. What can you infer from the passage?

　　A. Dogs are not kept as pets in Spain.

　　B. Rey was punished because he had not been loyal to his

　　owner.

　　C. The typewriting death is named because a typewriter is used in the punishment.

　　D. Rey didn't behave very well in the hunting. 答案與解析：D

　　最后提到，這種懲罰用于狩獵中“追兔不力，惹惱主人”的獵狗。 19. The passage mainly tells the readers about ________.

　　A. the cruel killing of dogs in Spain

　　B. how Rey was saved by rescuers

　　C. how Spanish dogs hunt hares

　　D. the fate of the dogs in Spain

　　答案與解析：A　文中提到了，西班牙獵狗的各種悲慘結局，并以Rey的遭遇具體闡述。因此選擇最合題意的A項。

　　Ⅲ.七選五 根據短文內容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。

A. As；that

　　B. What；that C. It；that

　　D. It；whether

　　答案與解析：D　分析句子可知，第二空后面的句子應該是真正的主語，所以前面用it作形式主語，that和whether都可引導主語從句，whether表示“是否”，符合句意“火星上是否存在某種形式的生命尚不知曉”。

　　2. That could be really exciting！But I still find it hard to imagine.那真是激動人心！但我仍然覺得難以想象。 find it hard to imagine，其中it是形式賓語，代替不定式to imagine，形容詞是賓語補足語。能夠用這種復合賓語結構的常見及物動詞包括find，think，believe，consider，suppose，feel，make等。 She felt it necessary to tell you the truth about the quarrel between the couple. 她感覺有必要把那夫妻倆爭吵的真正原因告訴你。 We think it a pity for them to miss such a wonderful lecture given by the heroes. 我們認為他們錯過那些英雄的精彩演講將是一件非常令人遺憾的事情。
