优质回答与知识(10)

The cactus is a thorn all over the body, is a very unique guy. It has only a stem like the palm of its hand, and its leaves are clusters of thorns. Like other plants, it blossoms and bears fruit. Its flowers are yellow, shaped like the ancient drinking cup, its fruit is dark red, like a small red cylinder. From a distance, cactus looks like a green electric mosquito clap. From close up, you can see that there are many stems. You can't underestimate these stems. They can store a lot of water. Overnight dew or a drizzle is enough for cactus to use for a month. As long as there is a little nutrients, no matter where it is born, cactus can live tenaciously, its vitality is really strong. We should be like cacti, be strong-willed people.

faint voice which nobody.里面都可以玩,image.baidu/www.wLtqqaj.com?phsc·····························操作性定义指根据可观察、可测量、可操作的特征来界定变量的含义,即从具体的行为、特征、指标上对变量的操作进行描述,将抽象的概念转换成可观测、可检验的项目。操作性定义是研究变量或有关概念与实际观察或活动之间的桥梁。将研究变量的抽象化形式转变为可观察、测量和操作的具体形式。操作性定义有两种,一种是测量的操作性定义,另一种是实验的操作性定义。给一个名词写出操作性定义的基本方法:1、做出该词的概念性定义;2、分析变量的内涵,找出概念的主要特征;3、将变量的主要特征具体化为若干可操纵的要点,或用可观察、可测量的词语加以表达。这些要点应覆盖和反映变量的基本内涵;4、将各要点按一定的逻辑顺序和语法规则进行文字修整,从而形成操作性定义。
