1. The traffic was heavy with
declivity , the truck was on the right side of the road .

下坡的路上车流如潮,大卡车大都行驶在右车道上。
2. To take away this discouragement, I resolved to dig into the surface of the earth, and so make a
declivity.

为了扫除这个障碍,我决定把地面掘平,掘成一个向下斜的土坡。
3. But our difficulties seemed to be over, for ahead of us stretched a smooth
declivity , along which the young folk bounded while I followed cheerfully behind.

困难似乎并不存在,眼面前是一段平坦的下坡土路,年轻人跳跳蹦蹦,走了下去,我也像年轻了一样,有说有笑,跟在他们后头。
