　　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.

　　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 (转向)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 答案与解析：C　hang在这里是“绞刑”的意思，文中第三段提到“勒住Rey脖子的绳子”。因此选择C项。 17. The underlined word“ vet” ( in Paragraph 5 )probably means“________”．

　　A. animal doctor

　　B. ambulance

　　C. animal medicine

　　D. equipment 答案与解析：A　给动物处理伤口的职业，只有“兽医”最合适。 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. 答案与解析：D

　　最后提到，这种惩罚用于狩猎中“追兔不力，惹恼主人”的猎狗。 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

　　答案与解析：A　文中提到了，西班牙猎狗的各种悲惨结局，并以Rey的遭遇具体阐述。因此选择最合题意的A项。

　　Ⅲ.七选五 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

　　The 1990s saw great changes in the way people communicate. People could send mail without going to the post office, and go shopping without leaving home. Words like e­mail and download became part of people's vocabulary.

(clear，apparent，obvious，possible，probable，likely，certain，natural...)that 从句(谓语形式用陈述语气) (2)It is n．(a pity，shame，one's duty，no use，no good，no wonder，no surprise...)that 从句(谓语形式用陈述语气) (3)It is＋p.p(said，believed，known，recorded，estimated，announced，expected...)that 从句(谓语形式用陈述语气) (4)It is adj.(necessary,important,essential，...) /v­ed(suggested,recommended,demanded,required...)that 从句(谓语形式用should do/be) (5) It is adj./n./p.p who, what, how，why，when，where，whether从句(谓语形式用陈述语气) [考试题] ①(北京东城区)________is unknown________there is life of some kind on Mars. A. As；that

　　B. What；that C. It；that

　　D. It；whether

　　答案与解析：D　分析句子可知，第二空后面的句子应该是真正的主语，所以前面用it作形式主语，that和whether都可引导主语从句，whether表示“是否”，符合句意“火星上是否存在某种形式的生命尚不知晓”。

　　2. That could be really exciting！But I still find it hard to imagine.那真是激动人心！但我仍然觉得难以想象。 find it hard to imagine，其中it是形式宾语，代替不定式to imagine，形容词是宾语补足语。能够用这种复合宾语结构的常见及物动词包括find，think，believe，consider，suppose，feel，make等。 She felt it necessary to tell you the truth about the quarrel between the couple. 她感觉有必要把那夫妻俩争吵的真正原因告诉你。 We think it a pity for them to miss such a wonderful lecture given by the heroes. 我们认为他们错过那些英雄的精彩演讲将是一件非常令人遗憾的事情。
