Standing in the rain, eyes closed, head tilted skyward.

　　站在雨中，閉上雙眼，仰著頭。

　　Smoke, black and boiling, shot skyward from the stack.

　　滾燙的黑煙從煙囪里朝天直冒。

　　As expected, the federal budget deficit is climbing skyward.

　　如預(yù)料的`，聯(lián)邦預(yù)算赤字迅速攀升。

　　Exponential curves start slowly, then rocket skyward toward infinity.

　　指數(shù)曲線先是緩慢開始，然后如同火箭直沖云霄般的趨于無窮。
