（一）
One day in 1848 Mr. Sutter made a remarkable discovery in the American River in California by his house. He noticed some bright yellow pieces in the water and bent down to pick them up. This was the beginning of the Californian Gold Rush.
Sutter realized the importance of the discovery. He sent a man to San Francisco to see the governor.
The people of San Francisco did not believe him at first. But a reporter of a weekly newspaper there went to Sutter’s house to make a report. When he came back he ran through the streets of the town shouting, “Gold! Gold!”
Within a month almost the entire population had gone to look for the precious（贵重的）metal. Soldiers deserted the army, sailors left their ships and men gave up their jobs so as not to miss the chance of becoming rich.
The news spread across America to Europe and thousands of people joined in the search. Some sailed round Cape Horn to reach California. Some chose the overland route across America and trains were formed for travelers to make the journey. Even then there were some who were prepared to cross the terrible desert of Death Valley in order to reach the gold a few days before the others.
The Gold Rush proved a disaster for Sutter himself. For years he tried to stop the people from digging his land. They did a great deal of damage （损害）and killed one of his sons, and at the end of his life he was a poor man who continually stopped people in the street to tell them that gold is the devil（恶魔）.

After a week he began visiting the bank. He showed his passport. “Nothing has come for you”, he was told. This went on for two weeks and Mr. Frank got very worried.
In the fourth week Mr. Frank was sent to prison for failing to pay his hotel bill. He had to

When he came out, he went immediately to the Fisher Bank. There was a new clerk there. “Have you received $500 for me? My name is Jackson Frank.” he asked.
The clerk checked his books. “Oh, yes. It came two months ago.” He said and showed Mr. Frank the order.
“But my name is Jackson Frank, not Frank Jackson.”
“That’s all right. It was in our books under the letter J.” The clerk laughed.

We want our kids (小孩) to use the Internet, and yet we worry. But we can find ways to direct our children away from what’s wrong, towards what’s best.
The most effective (有效地) way to monitor (监控) a kids’ online activity is to monitor it. That is, to stand beside the computer from time to time when your child is at it.
Carleton Kendrick suggests that accompanying (陪伴) your child to a website (网站) he often visits is no different from “checking out a playground where your kids go, to see that it’s safe.
In any e-mail program, a look at the senders’ addresses can give you a good idea of your kids’ correspondents (通信者).
America Online allows parents to limit incoming e-mails to a finite (限定的) list of
corre spondents. Some parents also type their kids’ names into a search engine to discover what they’re saying on websites or message boards.
Understand that as kids get older and demand more privacy (私密), some basic know-how comes into play. America Online has been particularly effective in helping parents give their children an online experience, a “kids-only’ AOL account (帐户) prevents young users from all but full time-monitored chat (聊天) rooms. Katherine Borsecnik, president at AOL, notes, however, that “if I have a child who’s doing a report on breast (乳房) cancer (癌), I might want to turn off the filters (过滤器)”since kids-only access (路径) would block websites with even straight medical information about breast.
Many parents don’t know that a simple click (点击) on the “history”tab (键) will produce a list of links to every website the computer has visited recently. Bonnie Fell opens all the files that have been downloaded (下载) by her two sons at least once a month—”whether the boys are there or not. Although they know it.” As Jim Lynch, who manages message boards for the Boston-based FamilyEducation. com, says, “Parents are the ultimate (最后的) filter.”
1. To stand beside the computer from time to time when your child is at it is .
A. the most effective way to monitor a kid’s online activity
B. the useful way to direct it away f rom what’s wrong and towards what’s best
C. the good way to protect it on the net
D. checking out a playground where your kids go, to see that it’s safe.
2. To protect their children on the net, parents can .
a. accompany their children to the website they often visit
b. look at the senders’ addresses
c. limit incoming e-mails to a finite list of correspondents
d. type their kids’ names into a search engine to discover something
A. ab
B. ac
C. abd
D. abcd
3. America Online .
A. prevents young users from all but full time-monitored chat rooms
B. blocks websites with even straight medical information
C. produces a list of links to every website the computer has visited recently
D. turn off the filters
4. Which of the following is right?
A. Katherine Borsecnik says parents are the ultimate filter.
B. Carleton Kendrick says accompanying a child to a website is the same as checking out a
playground
C. Jim Lynch says she might want to turn off the filters
D. Bonnie Fell says she opens all the files of her two sons whether they are there or not
（八）
A young woman rode with her new husband in a wagon (四轮马车). They came to a log cabin (小棚屋). The man shouted and a little boy came running out of the cabin. Sarah, the young woman, got down from the wagon, opened wide her arms and held the boy close.
“Hello, Abe Lincoln,” she said. “I think we’ll be good friends.”
The new mother with the smiling face went to work at once. She washed Abe and his sister
and tidied (整理) their hair. And that night she threw away the boy’s mattress (床垫) of leaves and gave him a soft mattress and enough blankets to keep him warm at night.
Sarah wove cloth and made new shirts for Abe. She made him new deerskin trousers and even deerskin shoes.
Maybe, if she had n’t come to the cabin, he wouldn’t have lived to be a man. When Abe’s father told him not to go to school any more and help on the farm, Sarah took Abe’s part against his father. Abe would rather read than eat, and when his father told him to stop, Sarah s aid, “Let the boy read.”
In 1830 the day came when Abe would leave home to work in New Salem. For the last time she had taken Abe’s part against his father. For the last time she had kept the cabin quiet so that Abe could read.
More than twenty years later, when Abe, who had then become famous, was going to make a speech in a nearby town, Sarah went there just to watch him. In the crowd she tried to make herself small, but he saw her and, in front of everybody, got out of his carriage and went over and put his arms around her and kissed her. Yes, that was her Abe.
“He loved me truly,” she said later.

B. Abe wouldn’t have helped his father on the farm
C. Abe wouldn’t have had so much time to read

现代教育技术复习资料-知识点归纳
现代教育技术复习资料 1．技术在教育教学中的作用（5点） ①作为学习检测的工具，帮助学习者和教师对学习过程及学习效果进行设计、追踪监察和评价反思。 ②作为媒体，承载和传递各种类型的教学信息。 ③作为信息工具，帮助学习者对各种类型的数据资料进行加工处理，并设计成新的信息。 ④作为社群工具，支持学习者与学习社群成员的交流互动。 2．技术作为学习工具的作用和价值（角色和功能p4） 信息工具（获取资源/探究知识，支持在建构中学习）； 情境工具（创设情境，支持在做中学）； 交流工具（支持协作学习）； 认知工具（支持高阶学习，发展高阶思维）； 评价工具（记录学习过程，展示学习作品，促进反思）； 效能工具（提高学习效率，支持知识的建构） 3．教育技术的AECT’94定义：教育技术是对学习过程和学习资源进行设计、开发、利用、管理和评价的理论与实践。 4．教育技术的AECT’05定义：教育技术室通过创设、利用、管理适当的技术性的过程和资源，以促进学习和改善绩效的研究与符合伦理道德的实践。5．05定义与94定义的区别（4点） ①05定义采用的是“educational technology”(教育技术)，而在94定义采用的是b“instructional technology”(教学技术)。 ②05定义主要包括3个范畴：创设、利用、管理，其中94定义中的设计、开发职能在新定义中演化为一个职能：创设。在新定义中，评价范畴也不再被列为一个单独的范畴，已经将其融入创设、利用、管理中。 ③05定义添加了有关改善绩效的新内容。改善绩效的提法强调了学习的含义不单指获取知识，更要注重培养和提高能力。 ④05定义更加强调过程和资源的技术性与合适性。倾向于认为教育技术的技术性是教育技术区别于教育领域中其他过程或资源的根本所在。 6．现代教育技术的发展趋势 随着现代科学技术的发展和教育信息化建设步伐的加快，教育技术也将不断发展，其发展趋势主要体现在以下几个方面： ①教育技术作为交叉学科的特点日益突出，其应用及研究将走向生态化的发展道路，教育技术是与教育学、心理学、哲学、通信技术学等多种学科息息相关的交叉学科； ②在教育技术研究领域中，开始从重视技术应用过渡为重视技术的设计与效果检
