ll be traveling fast, so despite the distance, it will not be like diving into the deep end of a pool. It will be like he is diving into the shallow end. Skydiver preps for the big jump When he jumps, he is expected to reach the speed of sound 690 mph (1,110 kph) in less than 40 seconds. Like hitting the top of the water, he will begin to slow as he approaches the more dense air closer to Earth. But this will not be enough to stop him pletely. If he goes too fast or spins out of control, he has a stabilization parachute that can be deployed to slow him down. His team hopes it39。突然想到那件藍(lán)格子襯衫;那些被折成各種各樣形狀的信紙 ;那段從街角深巷伊始的友誼;還有那場(chǎng)還沒有開始就宣告了終結(jié)的邂逅計(jì)劃 …… 那些年那些天的非做不可,終于和青春一樣,都將在我們的人生中謝幕。 Have declared the end of the encounter that haven39。 Those were broken into various shapes of stationery。那些曾經(jīng)所謂的非做不可,只是青蔥年華里自己給自己注射的一支強(qiáng)心劑,或者說,是自以為是的精神寄托罷了。也曾經(jīng)好像已經(jīng)下定了決心去做某件事,但更多的時(shí)候是最后又打起了退堂鼓。s time, your ideas are always special to clear. Want, want, line is clear, as if nothing could shake his. Also once seemed to be determined to do something, but more often is he backed out at last. Dislike his cowardice, finally found that there are a lot of love, there are a lot of miss, like shadow really have been doomed. Those who do, just green years oneself give oneself an arm injection, or is a selfrighteous spiritual. 一個(gè)人的時(shí)候,自己的想法總是特別地清晰。 Originally, this world, can produce a chemical reaction to an event, in addition to resolutely, have to do, and time. 原來,這個(gè)世界上,對(duì)某個(gè)事件能產(chǎn)生化學(xué)反應(yīng)的,除了非做不可的堅(jiān)決,還有,時(shí)間。t want to give vent to out your inner voice can be in the high school children of the feelings in a period, but was eventually infarction when graduation party in the throat, later again stood on the pitch he has sweat profusely, looked at his thrown a basketball hoops, suddenly found himself has already can39。t really grow up, it seems is not so important。 The end of our life, and can meet many things really do? 而窮盡我們的一生,又能遇到多少事情是真正地非做不可? During my childhood, think lucky money and new clothes are necessary for New Year, but as the advance of the age, will be more and more found that those things are optional??傆X得自己自己似乎應(yīng)該去做點(diǎn)什么,或者寫點(diǎn)什么。 May be back in the past, to oneself the paranoid weird belief disillusionment, these days, my mind has been very messy, in my mind constantly. Always feel oneself should go to do something, or write something. Twenty years of life trajectory deeply shallow, suddenly feel something, do it. 一字開頭的年齡已經(jīng)到了尾聲。s actions.
