问题 Opponents of genetic engineering claim that scientists are tampering with matters that they know little and essentially committing a crime against nature.
选项 A、that they know about little
B、that they know little about
C、they know about that little
D、about that they know little
答案 B
解析 本题重点考查常见动词与介词的搭配。画线部分是定语从句，修饰matters。四个选项中只有A和B是定语从句结构。know about是“听说，了解”，know是不及物动词，需要搭配介词才能跟宾语；后者know sth．about中know是及物动词，与about搭配，表示在某方面比较熟悉。故选B。
