Dsipatch??

老師派發試卷
The teacher distributes the examination papers.

Distribute = 分派，派發

Dispatch = 派遣 e.g. The emergency operator dispatches an ambulance to the caller's address immediately.

Dispatch 也有解作分派的，不過通常不是當面派發，而是間接的。例如： He dispatched all the parcels via couriers.

The board of education dispatches the examination papers by couriers, to arrive at various examination centres only one hour before the examination starts.

The teacher in each examination centre distributes the examination papers to the students five minutes before the examination starts.

The teacher dispatches the exam. paper. 在文法上正確但用法不正確.dispatches一般用於發放東西如dispatch cargo. 這句子用distribute比較恰當.
The teacher distributes the exam. paper.
