正确答案及解析
正确答案
解析
[参考答案]来自学习结果的种种反馈信息，对学习效果有明显影响。一方面，学习者可以根据反馈信息调整学习活动，改进学习策略；另一方面，学习者为了取得更好的成绩或避免再犯错误而增强了学习动机，从而保持了学习的主动性和积极性。对学习结果进行评价，能激发学生的学习动机，对学习有促进作用；适当的表扬的效果优于批评，所以在教学中要给予学生表扬而非批评。虽然表扬和奖励对学习具有促进作用，但使用过多或者使用不当，也会产生消极作用。滥用外部奖励，不仅不能促进学习，还可能破坏学生的内在动机。

方式二：纵观中国历史上的改革，有成功的，例如商鞅变法使秦国慢慢强大起来，北魏孝文帝改革促进民族融合；也有失败的，例如我们今天学习的戊戌变法，虽然失败了，但是客观上也推动了中国社会的发展和进步。是符合历史发展潮流的。

The iPhone can run allsorts of applications such as those help you to lose weight, identify a song onthe radio, find a restaurant or do many other things.
For the futurist
The T-Mobile G1 is very popular as it is thefirst phone to offer a Google browser, meaning that you′re getting the real webon your phone, but it′s the phone′s potential that qualifies it for the futurist.The exciting applications are interesting, but they don′t always work smoothly.Sometimes it is hard to use the applications it comes with. The system shouldimprove as it becomes more popular, so it holds great promise. With fewrestrictions on the design of applications for the phone,
the G1 could be the first phone toincorporate (整合) some of the coolest.
For the road warrior
The new BlackBerry Storm is something likethe equivalent (等同物) of a mullet--a business up front, party in the back. It stillincorporates the serious mail and organization features that have endeared (使受钟爱) these phones to business people. The 3.25-inch is bright anddetailed and it′s a decent size for watching videos on the go.
For the Luddite (反对技术进步的人)
For those who can′t handle buttons and newfeatures, there is the Samsung Jitterbug Dial. Some people are Luddites whojust want a few large buttons to make calls. That′s it, just calls. That makesit even easier to use an iPhone.
