阅读下面的文字，根据要求写一篇作文

一只蜜蜂看到一株百合花在流泪。“美丽的百含花，你为什么悲伤呢？”蜜蜂不解。“明天或者后天，我将凋谢，我的美丽将消失，我怎能不悲伤呢？”百合花答道。蜜蜂问：“你是否孕肓了种子？”百合花顿悟。生活中，只要你拥有美丽的种子，那绚丽的花儿还将再现，心田上的百含花是常开不败的。

这段文字意味深长，对我们颇有启迪，在自然界，有花才有种子，同样，因为有了种子，所以绚丽的花才会再开；对于人生而言，有了“种子”，“心田上的百合花”也才能“常开不败”。我们每个人都有精神的心灵的花，也希望结出饱满充实的种子。

（甲）

客曰:“‘月明星稀，乌鹊南飞’，此非曹孟德之诗乎？西望夏口 ， 东望武昌 ， 山川相缪，郁乎苍苍，此非孟德之困于周郎者乎？方其破荆州，下江陵，顺流而东也，舳舻千里，旌旗蔽空，酾酒临江，横槊赋诗，固一世之雄也，而今安在哉？ 况吾与子渔樵于江渚之上，侣鱼虾而友麋鹿，驾一叶之扁舟，举匏樽以相属。寄蜉蝣于天地，渺沧海之一粟。哀吾生之须臾，羡长江之无穷。挟飞仙以遨游，抱明月而长终。知不可乎骤得，托遗响于悲风。”

苏子曰:“客亦知夫水与月乎？ 逝者如斯，而未尝往也；盈虚者如彼，而卒莫消长也。盖将自其变者而观之，则天地曾不能以一瞬；自其不变者而观之，则物与我皆无尽也，而又何羡乎!且夫天地之间，物各有主，苟非吾之所有，虽一毫而莫取。惟江上之清风，与山间之明月，耳得之而为声，目遇之而成色，取之无禁，用之不竭，是造物者之无尽藏也，而吾与子之所共适。”

元丰二年十二月，余自吴兴守得罪，上不忍诛，以为黄州团练副使，使思过而自新焉。

其明年二月至黄。舍馆粗定，衣食稍给，闭门却扫，收招魂魄，退伏思念，求所以自新之方。反观从来举意动作，皆不中道，非独今以得罪者也。欲新其一，恐失其二，触类而求之，有不可胜悔者，于是喟然叹曰:“道不足以御气性不足以胜习不锄其本而耘其末今虽改之后必复作盍归诚佛僧求一洗之”。

得城南精舍曰安国寺，有茂林修竹，陂池亭榭。间一、二日辄往，焚香默坐，深自省察，则物我相忘，身心皆空，求罪垢所以生而不可得。一念清净，染污自落，表里翛然，无所附丽，私窃乐之。旦往而暮还者，五年于此矣。

（节选自苏轼《安国寺记》）

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

    There is an old Spanish Proverb which states, “Tomorrow is often the busiest day of the week”. I'd say, too many. Our dreams should not, and cannot wait. We have to go for them now! Here's why.

    1）

    Nobody likes to talk about death, but the reality is – everybody is going to die at one point. None of us know the day, or the hour. Therefore, today is all we have. Don't go to your grave with unfulfilled dreams. Make the decision to go after every dream, big or small right now.

    2）The world is waiting on your gift

    I know this may be hard to believe, but the world is waiting on YOU! Yes, YOU! Sure, other people may be able to sing. But they'll never be able to sing exactly like you. Sure other people can write, but they'll never be able to write from the same perspective in which you write. Don't deprive（使丧失） the world of your gift. It's the oxygen that we need to survive. Thus, it is your responsibility to figure out exactly what your gift is, and use to better your life and the lives of those around you.

    3）

    You can dream about writing the great American play that you want, but it's never going to happen unless you actually put pen to paper. You can dream about finding a cure for cancer, but it will never happen unless you actually go to school to become equipped with the necessary tools to find that cure. They require you to get your head out of the clouds, and actually do the work to make them happen. Get to it!

A. You can't let fear win.

B. Tomorrow is not promised.

C. In other words, dreams don't work unless you do.

D. Possibilities you never knew existed are waiting on you

E. How many times have we put off our dreams until tomorrow?

F. Unless you take the first step, your dreams will never come true.

G. You were born into the world with a unique gift, which nobody on this earth can copy.
