问题 The title which best expresses the content of the text is _____.
It can be learned from the text that the teachers ban harmful experiments to animals in order to _____.

选项 A、maintain ecological balance.
B、please animal welfare groups.
C、get financial support from their sponsors.
D、protect necessary harmless experiments on animals.

答案D

解析 推理判断题。本题问:从课文中可以了解到,教师禁止对动物进行有害试验的目的何在?第1段第2句写道:"The National Association of Biology Teachers and the National Science Teachers Association hope to end animal abuse in elementary and secondary schools and,in turn,discourage students from mishandling animals in home experiments and science fair projects".从画线部分可以看到教师要禁止的是"滥杀动物"和"虐待动物"。最后一段最后一句写道:"The association may set up seminars to teach better animal care to its members".(协会可以举办研讨会培训教师更好地保护动物)。可见,教师禁止的是"harmful experiments to animals"以便"protect necessary harmless experiments on animals"。
