单项选择题
Human beings are superior to animals that they can use language as a tool of communication.
A．in that
B．in which
C．for that
D．for which
答案
参考答案：A
解析：连词应用。从意思判断，本题的句子是原因状语从句。在四个选项中只有从属连词“in that”可表示“由于，因为”，如：Criticism and self-criticism is necessary in that it helps us to correct our mistakes．批评与自我批评是必要的，因为能帮助我们改正错误。因而应选A。
