　　I went to summer camp with my classmates last summer. I never forget the

days.

　　Early in the morning, about 200 children from Grade. Seven came together

at the bus station from different schools. After saying goodbye to our parents, we

got on the buses. It took us more than two hours to arrive at the campground in

Qingdao.

　　We were laughing, shouting, jumping and running like birds when we got off

the buses. For us, It was our first time to be away from our parents .    

　　Swimming was my favorite class. It was about one o'clock in the afternoon.

It is the warmest time of a day and the best time to stay in cool water. With the

help of my swimming teacher, l could swim very well.

　　During the holiday, I learned many new things and made many new friends.

How happy I was!

据报道，T市政府注重发挥市科学技术协会的“智囊团”作用，组织科技工作者积极参与党和政府对重大科技、经济、社会问题的决策论证，开展各种形式的献计献策活动，使各项决策更加民主化、科学化。例如，鉴于材料工业发展对T市这样的加工型工业城市具有重大影响，T市政府依靠科协组织专题研讨，获得有价值的决策建议65条，市政府采纳其中关于能源开发、节约、管理等方面的14条建议后，产生了良好的经济效益，全市一年就节约标准煤20万吨，节电884万千瓦。又如，T市政府为寻求工业技术进步的决策依据，依靠科协组织16个学科的专家论证全市科技发展10年规划和“八五”计划纲要，采纳了专家建议67条，占所提建议的80%以上；T市科协还先后组织了“城郊农业发展战略”、“新型工业区开发建设”、“控制T市地面沉降”等项对策研究，为市政府决策提供了可靠的科学依据。
