1. Like adolescents they stand before the mirror, and still cannot fathom the exact outline of the vision before them.
    犹如希腊神话中那位漂亮的少年，站在镜前，不能辨认自身的真面目。

2. An outline often helps in the coordination of ideas.
    拟个提纲常常有助于理清思路。

3. Carefully, to avoid injuring her, I rub cream into the yellow skin, which rolls freely over the bones, feeling perfectly the outline of each bone in the back.
    为了不伤着她，我小心翼翼地把护肤霜揉在她发黄的皮肤上。她的皮肤松松地在骨头上滑动，背上每块骨头的轮廓都能清楚地摸到。

4. In the gloom I could only just discern the outline of a building.
    在黑暗中我只能依稀分辨出一座建筑物的轮廓来.
