steep, sheer,vertical 这些形容词均含有“陡峭的,险峻的”之意,从“陡”的程度来看,大致为:steep < sheer < vertical
1. steep 指坡度向上逐渐增加的斜陡坡,强调险峻,暗示难于攀登。如:
Steep stairs may leave you giddy and faint. 陡直的楼梯可使人头晕目眩。
They were both breathing hard from the steep climb. 从悬崖爬上来之后,他俩都很费力地喘着气。
2. sheer 指自始至终近于垂直的陡峭,不仅仅很难爬上去,甚至于不可能攀登,英文词典对它的解释是almost vertical, very steep。如:
The cliff plunged in a sheer drop down to the beach. 悬崖陡峭直下海滩。
The river runs between walls of sheer rock. 小河从峻峭的岩石中间流过。
3. vertical指相对于另一线或平面,或相对于地面,是垂直的、竖的、直立的,与steer相对,更“陡”,即“陡”到了“垂直”的程度。如:
The climber inched up a vertical wall of rock. 攀登者慢慢爬上了陡直的石壁。
The gadget can be attached to any vertical or near vertical surface. 该装置可以装在任何垂直或近似垂直的平面上。
