可视性

The secondclass visually sensitive areas mainly were the smaller slope closeshot zone,and mediumshot zone and wideshot zone of all mountains,which had strong visibility and should actualize landscape reconstruction.

二级视觉敏感区主要是坡度较小的近景带和山体的中、远景带区域，可视性强，应重点开展景观改造。

This is partlydue to the visual nature of the presentation, andpartly because whiteboards offer ways of activelyengaging pupils in activities.

这一部分是因为板书的可视性本质，另一部分是因为白板在活动中提供鼓励学生的方式。
