解析 control group 控制组 experimental group 实验组,试验组 简单的的实验通常包含一个实验组和一个控制组. 控制组对组内进行实验操作. 实验组不对组内进行实验操作. 两组内的成员随机分配.以达到对比效果,这样得出实验操作与实验结果相关的结论. 分析总结。 以达到对比效果这样得出实验操作与实验结果相关的结论...

解析 A 答案:A 本题考察旳是考生对细节旳把握。答案在第二段“In the experimental group,the parents were given a two-hour training session”(在进行试验旳这一组里,给家长进行两小时旳培训),文章旳调查研究中把孩子及其家长提成两组,显然区别在于试验组里旳家长接受了培训。反馈 收藏 ...
control group 对照组experimental group 实验组我想实验组是在正常情况条件下进行科学实验的，而对照组则是在条件不同的情况下，同样的实验，看有什么差别，科学家来进行对比。控制
In anexperiment, data from an experimental group is compared with data from a control group. These two groups should be identical in every respect except one: the difference between a control group and an experimental group is that the independent variable is changed for the experimental group, ...
