     2012 is a good film. If I were you, I'd like to watch it. The words, "Everyone is equal,

and everyone has his chance of survival" , have been shocking to us.

     Things begin in 2009,as an Indian scientist has made a strange discovery:It seems that there are serious storms on the surface of the sun, which are having a great effect on earth. By 2010 the US President calls

a meeting with seven other famous world leaders at the G8 summit in Spain. He says the

world's top scientists have found out that the world will soon come to an end.

     Finally we reach the year 2012. By now, signs have been appeared. The west coast is with so-called "mini earthquakes",  and fissures (裂缝) often appear in the earth.  But people are going about their daily

lives as usual.  At this time, Jackson Curtis is going on a driving trip with his two young children in Yello

wstone National Park.

     Jackson and the kids arrive at Yellowstone to find that some parts of the park have been taken over for reasons they don't know.

     At the same time world leaders are planning to choose excellent people from all over the earth, and let

them get out of the cataclysm (灾难) by special built ships. Everyone else will be left to death.

     Jackson, of course, is not one of those chosen to be saved, but he tried his best to get on the ship with his family. The movie ends with a view of the Earth from space, showing a changed African continent.

    Education is not an end, but a means to an end. In other words, we do not educate children only

for the purpose of educating them. Our purpose is to fit them for life.

     In some modern countries it has for some time been fashionable to think that by free education for

all - one can solve all the problems of society and build a perfect nation. But we can already see that

free education for all is not enough; we find in such countries a far larger number of people with

university degree; they refuse to do what they think "low" work; and, in fact, work with hands is thought

to be dirty and shameful in such countries. But we have only to think a moment to understand that the

work of a completely uneducated farmer is far more important than that of a professor; we can live

without education, but we die if we have no food. If no one cleaned our streets and took the rubbish

away from our houses, we should get terrible diseases in our towns…

     In fact, when we say that all of us must be educated to fit us for life, it means that we must be

educated in such a way that, firstly, each of us can do whatever work suited to his brains and ability

and, secondly, that we can realize that all jobs are necessary to society, and that is very bad to be

ashamed of one's work. Only such a type of education can be considered valuable to society.

A. our society needs all kinds of jobs

B. our society needs free education for all

C. a farmer is more important than a professor

D. work with hands is the most important

3. The purpose of education is _______.

A. to choose officials for the country

B. to prepare children mainly for their future work

C. to let everyone receive education fit for him

D. to build a perfect world

2009年中央“一号文件”再次聚集“三农”。始于1978年的农村改革，风雨兼程30载，中央先后制定出台了11个“一号文件”顺应和指导了农村改革，给我国农村带来了巨大变化。从“皇粮国税”、“三提五统”到免征持续了2600多年的农业税，再到给予农民补贴；从城乡分割到统筹城乡，进而逐步实现城乡一体化……，给中国农民留下了一串温暖的记忆。改革开放30年来，中 * * 党为什么能够给我国农民留下一串温暖的记忆？
