易错句子We did an experimental to test the new drug.
正确表达We did an experiment to test the new drug.
表示“做实验”时，宾语要用名词 experiment；experimental 只能作形容词，不能放在冠词 an 之后像名词一样单独使用。汉语“做一个实验”里的“实验”本身就是名词，不能因为英语形容词常以 -al 结尾，就把这个形容词反过来当成名词来用。

易错句子The new method was tested experimental on mice.
正确表达The new method was tested experimentally on mice.
修饰动词 was tested 要用副词 experimentally；experimental 只能修饰名词，如 an experimental method。汉语的“实验”没有形容词与副词的形态区别，所以学习者容易把形容词直接拿来作状语，漏掉 -ly。
