问题 All the people present at the conference are ______ and they will discuss some teaching problems.

选项 A、mathematics teachers
B、mathematics teacher
C、mathematic teachers
D、mathematic’s teachers

答案A

解析表示科目的名词可以直接和另一名词连用，如句中表示“数学老师”，应用mathematics(数学)+teachers(老师)。故选A。没有mathematic这个词。句意：到会的全是数学老师，他们将讨论一些教学问题。
