我们沿着山坡费力上了山脊。

They occupied the city without striking a blow.

他们毫不费力占领了这个城市。

He was pushing a handtruck with difficulty.

他费力推着手推车。

Keep your nose to the grindstone and you should pass the exam easily.

刻苦学， 能不费力气过考试。

我费力峭壁下，感觉暖洋洋的。

They won the game without striking a blow.

他们毫不费力赢得了比赛。

I clambered out of the trench.

我费力出壕沟。

He tossed off a sonnet.

他毫不费力作了一首十四行诗。
