100 meter track is not long,
The athletes spirit lifted.
Waving their fists jump want to try,
Will won the first prize against the clock.

The gunfire with you to embark on the journey,
Your head erect confident,
With the will to win,
Rushed, and ran.
Moment time seems to have stopped for you,
Your courage shook everything,
Your pace,
That is hard sweat to express,
Although only a short period of ten seconds,
But you left in our hearts forever.

鼠目寸光 光彩夺目 目中无人 人仰马翻 分秒必争 争先恐后 后来居上 上下同心

千钧一发 迫在眉睫 危在旦夕 十万火急 急于星火
四面楚歌 救火扬沸 一触即发 朝不虑夕 岌岌可危 火烧眉毛 十万火急 危如累卵 命悬一线 燕巢幕上 朝不保夕 盲人瞎马

当你知道一件事的重要性,或者为自己的前途担忧时,会真正激起你心中的紧迫感与你真正的潜能.
所以要培养你的时间观,就必须为自己设定目标,有种动力.
