两株扁豆

春天,外公种了两株扁豆。一株靠近路边,另一株在墙角里。靠近路边的这株因为施肥浇水方便,外公便不时把弄,而墙角里的那株因为不便,只好由它自然生长。开始,两株扁豆藤的肥瘦、粗细、长短并没有太大的差别。到了五月底,路边的这株,明显地比墙角那株丰茂了许多。我暗地里猜度,外公是因为怕麻烦,才忽视墙角里的那株扁豆的。到了九月,两株扁豆藤竞相开花,路边的这株花稀而大,墙角的那株花密而小。路边的这株结的扁豆大而薄,产量较低,吃起来口感也较差。墙角的那株扁豆厚实饱满,产量是路边这株的五倍多,吃起来肉实厚重,很有嚼头。对这种结局,我…     

我们是一株株小树

我们是一株株小树 我们愿像一粒粒的优良树种 园丁将它播撒在园间苗圃 让它发芽长叶生根 长成亭亭玉立的树株 辛勤的园丁 又将它植往田间远处 浇水,施肥,植进踏实泥土 让它的根系粗壮 扎入很深的泥土 让它长成壮实枝杆 长出有力的绿色叶片 让它成长高大树杆 为人类做奉献 这一株株的小树 正是祖国千百万少年儿童的象征 有党的阳光 培育成长 让我们去做优秀队员 让共产主义品质不断增长 在我们心灵的深处发光 伟大的母亲—祖国 让我们顽强学习 天天向上 让我们刻苦锻炼 体魄更加健壮 让我们顽强斗争 意志更加坚强( 成为冲锋陷阵的标兵 能在科…     

两株牵牛花

在墙边,花朵娇艳,枝繁叶茂,让人神清气爽。走近来看,原来是两株牵牛花的杰作。左边一株缠绕着一根木杆爬上了墙头开出了鲜艳的花朵。右边一株则是绕着三根木杆努力地向墙头爬去,它的藤枝越来越长,叶子也越来越茂盛。     

甘蓝型杂交油菜F1不育株与正常可育株生理差异及不育株对杂种优势的影响

研究了甘蓝型油菜杂交组合96F044D、96F045D、96F057D不育株及正常可育株根系伤流量、单位面积角果皮生产力和经济性状，万群体中不育株率以及3个杂交组合与常规油菜H045作对照的临界不育株率。结果表明不育株与正常可育株根系伤流量、单位面积角果皮生产力差异不显，经济性状差异显。相同不育系配制的杂交组合不育株率差异不显，3个杂交组合的不育株率显小于临界不育株率，杂种优势表现明显。     

两株老松树

两株老松树长在一起。暴风雨来临,其中一株忐忑不安地说:"这该死的暴风雨,迟早会要了我们的命!"另一株说:"我们就是在风雨中成长起来的,它铸就了我们无畏无惧的风格!"秋天的脚步近了,一株松树担忧地说:"又是一年结束了,时间真是悄然无声呀!"另一株说:"我们的年轮又多了一圈,药用价值更高了!"     

一株花儿

我家有一株花儿．虽然历经磨砺,但最终还是活了下来。她好像一直认为自己应该活下去．一定要活下去似的。她,就是长期“住”在我家院子里的一株小小的兰花。     

青海高原一株柳

<正>这是一株柳,一株在平原、在水边极其普通、极其平常的柳树。这是一株神奇的柳树,神奇到令我望而生畏的柳树,它伫立在青海高原上。在青海高原,每走一处,面对广袤无垠、青草覆盖的原野,寸木不生、青石嶙峋的山峰,深邃的蓝天和凝滞的云团,心头便弥漫着古典边塞诗词的悲壮和苍凉。走到李家峡水电站总部的大门口,我一眼就瞅见了这株大     

一株草

有时亲手种植的一株草,比林中的大树还要珍贵。一株草是微不足道的,但有了亲手种的心血就高贵起来。我常认为,做稻米生意的商人永远也不能了解种稻的农人,因为他没有下过田,稻米在他只是买     

一株两株三株四株草

<正>大自然中,随处都可以见到可爱的小草。甲骨文中,也有很多和小草相关的字。“草”的甲骨文写作“■”,字形像并排而生的两株小草,简化后,写作“艸”。今天的“草”字,其实是另外一个字“皂”,篆文写作“■”。“皂”的造字本义是指橡子,橡树的果实。后来,人们用“草”字代替“艸”字,草的本义就消失了。甲骨文中,草字还写作“■”,这是一株小草的样子,简化后写作“屮”。“屮”的造字本义是指小草刚刚长出来的样子。

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

Western and Eastern culture differences in commercial field

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
