答案

科学活动是指人们从事探索事物存在及变化的状态、原因和规律的实践活动,以及在科学知识、理论的指导下进行的实践活动. 科学活动是运用范畴、定理、定律等思维形式反映现实世界各种现象的本质和规律的有目的行动.故不符合题意.

A、调查是科学探究的常用方法之一.调查时首先要明确调查目的和调查对象,制订合理的调查方案.调查过程中有时因为调查的范围很大,就要选取一部分调查对象作为样本.调查过程中要如实记录.对调查的结果要进行整理和分析,有时要用数学方法进行统计观察是科学探究的一种基本方法.实验法是利用特定的器具和材料,通过有目的、有步骤的实验操作和观察、记录分析,发现或验证科学结论. 故不符合题意.

B、收集和分析资料也是科学探究的常用方法之一,收集资料的途径有多种.其中用摄像机拍摄蜜蜂采蜜的过程对获得的资料要进行整理和分析,从中寻找答案和探究线索,这也属于科学活动,故不符合题意.

C、观察法是在自然状态下,研究者按照一定的目的和计划,用自己的感官外加辅助工具,对客观事物进行系统的感知、考察和描述,以发现和验证科学结论.观察时要全面、细致、实事求是,并及时记录下来;要有计划、要耐心;要积极思考,及时记录;要交流看法、进行讨论.故不符合题意.

D、此项属于科学现象,不属于科学活动.故不符合题意.

故选:D

These days it is found that school students hardly have any sports. Is it because they have no       in sports? It may not be true. They often say they have        more important things to do.

What are these important things? Exams! They have to    __   themselves ready for all kinds of exams and tests in school. So many of them almost become  bookworms(书呆子). In the past in the summer holidays, they could do       they liked, but now they have to spend all their time preparing for exams. So       have kept them away from going in for sports.

Because of the pressure from        parents and teachers, they have to work harder and spend most of their time     __   books. As for the students themselves, they don’t want to       the lessons because they want to further their studies. So it is necessary to give all of their spare time to their studies and       up their school sports.  

It’s true a good education cannot go without physical training, the same is true, a quick mind hardly goes along with a        body. Without a strong body, you can never do anything well, how can you make great success in life?
