  2016年托福口语题目:

  2016年9月3日托福口语4.Maturation effect 研究人员在研究过程中,实验对象可能会因为自身的生长而产生变化,从而影响实验结论的准确性。教授讲了一项研究,研究人员以青少年作为实验对象,测试exercise能否对他们的体质造成积极影响。实验开始时科学家先测试了一下这些青少年的体质,一年以后又对他们进行测试,发现他们的体质果然有所提高。但我们却不能简单地得出结论说是锻炼提高了他们的身体素质,因为这也可能是natural process的结果。随着他们年龄的增长,他们会变得更强壮,这会影响实验结果。

  托福口语模板及参考答案:

  Maturation effect refers to the phenomenon that in the process of a research, a change in the condition of the experimental object which occurs naturally may affect the accuracy of an experiment. For example, the professor says that researchers did an experiment to see whether exercise could have a positive effect on the teenagers' physical health. At the beginning of the experiment, researchers examined the physical health of the teenagers. Then one year later they found that their physical health improved. Yet they couldn't just conclude that exercise helped improve their physical health. This was because natural process might also had affected the outcome of the experiment since as the teenagers grew, their muscle became stronger.
