I sit in the front of the report hall so that I can see the blackboard clearly.This result filled him with despair.I've been out of army since 5 years ago. 及时采纳,给分
始终不遇
这要看句子的意思是什么. 如果只是要学员把注意力放在黑板上,可以用 ‘ pay attention to the blackboard (把注意力放到黑板上)‘ 或是’look at the blackboard(看黑板)‘. 现在不是都很少用黑板了吗?如果是用’白板‘的话,改成’whiteboard就可以了.
