[说明]


银行金融系统对数据库中的数据安全要求很高,必须在技术层面上采用必要的措施,以保证数据的有效和不丢失。数据库的备份与恢复是保证数据安全的一种基本方法,通常将数据库备份划分为冷备份、热备份和数据导出,而数据导出根据导出数据的范围,又可以分为完全导出、增量导出和累计导出。
该金融系统上线初期,整个业务系统采用了内网方式运行,不与外网发生联系。为了保证数据库内部数据的安全,该银行信息中心的刘工提出的备份方案如表7-3所示。


信息中心的李工对刘工的方案提出了异议,认为数据库一旦发生故障,刘工的方案无法做到数据库的实时恢复,会导致业务数据的丢失,银行应该采用数据库冷备份和热备份相结合的方式来完成数据库的备份。
1. 请结合冷备份和热备份的概念及其技术特点,填补表7-4中的(1)~(6)空缺处。

有块自视清高的抹布。尽管它本身脏兮兮的,像是一张皱巴巴、邋邋遢遢的老脸,但它仍还要去清洁桌子,并大言不惭地说,只要它一去,再脏的桌子也准保手到“污”除。

然而,真枪实弹地干起来,它却揩去擦来,怎么也抹不干净,甚至越抹越脏。临了,它捋了把黑漆漆的汗珠子摔在地说:“桌子,实在是太脏了!”

桌子反唇相讥:“要想清洁别人,首先得清洁自己。”

要求:选好角度,确定立意,明确文体,自拟标题;不要脱离材料内容及含义的范围作文,不要套作,不得抄袭。

题型:阅读理解

 When he thought of the past, my grandfather would sometimes show us photographs of himself at school. They were brown and faded, and it was hard to believe that the blurred(模糊) figure of the little boy in the short trousers and socks could ever have been Grandfather. Besides, he wore a cap --- all the boys in the photographs wore caps pulled so far forward that half of their faces were obscured. When Grandfather asked us to pick him out from the group, we would surely point to the wrong boy.

On one such occasion my younger sister, aged six, burst into tears when Grandfather proudly guided her finger to the right boy. "How could that boy be you?" she cried. "He should have a beard." We were, of course, all convinced that grandfathers should have beards, preferably white and bushy, like our own grandfather's.

"I was a good scholar," Grandfather would say, wagging his beard over the photographs. "I should have been top of the class if I hadn't had to get up at six every morning to milk the cows and chop the wood, and again when I came home from school."

"But Saturdays? What did you do on Saturdays?"

"Saturdays, if it was fine, I'd be out all day in the fields with the men," replied Grandfather. "And if it was wet, I'd be helping my mother with odd jobs round the house. There wasn't much time for studying."

We all tried hard to imagine what it would have been like to have seen Grandfather getting up at crack of dawn and never, obviously, having a moment for himself. It seemed we had learnt something from what Grandfather had said about his childhood.

41. In the first paragraph of this passage, what the author really tells us is that ________ .

A. his grandfather used to wear short trousers, socks and a cap as well

B. it was difficult to tell which of the boys in the photographs was Grandfather

C. he didn't believe Grandfather wore a cap pulled forward when he was at school

D. it was fun to watch boys in the photographs wearing caps pulled forward

42. The author's sister burst into tears because________.

A. she did not get a chance to pick out Grandfather in the photographs

B. she was told which was the right boy before she herself could pick him out

C. other children did not agree with her that Grandfather should have had a beard

D. she found Grandfather in the photographs did not have a beard

43. When Grandfather said, "I should have been top of the class...", he meant ________ .

A. if he had had more time for studying, he would have been the best in his class

B. he should have spent more time studying rather than playing ball games

C. his school days should not have been so hard and miserable

D. he could have never been the best student even if he had studied still harder

44. In the last paragraph the author said, "We all tried hard to imagine..." because ________ .

A. the figures of the boys in the photographs were small and blurred

B. the children had never experienced life like that of Grandfather

C. the photographs Grandfather showed them were brown and faded

D. Grandfather failed to tell them about his childhood in detail
