I have a great mother. She cares much about me in my life and study.
In the morning, she gets up early to make breakfast for me. When I was little, she prepared my schoolbag. But now, she tells me to do it by myself. Because she thinks I have been old enough to do it. Besides, she always checks my homework. When I finish my homework, she checks it and points out the mistakes. She is very careful and helps me a lot.
I love my mother.
今天我来为大家介绍一下梧桐树
梧桐树,即“中国梧桐”,是梧桐科梧桐属的植物,别名青桐、桐麻,也属落叶大乔木,一般高达15米;树干挺直,树皮绿色,平滑。原产中国,南北各省都有栽培,也为普通的行道树及庭园绿化观赏树。我们所说的法国梧桐其实是悬铃木中的一种。
梧桐树的叶子极似枫树叶,甚至连脉络都一样。梧桐树的.叶子会变色哦!春天的时候,叶子是嫩绿嫩绿的;一到秋天,叶子就会慢慢变黄。这是为什么了呢?原来在夏天时,树叶工作得很努力,可是,天气转凉后,它就停止了工作。树叶所制造的营养也就不能送到树枝和树干上,而沉淀在叶子里。树叶的叶绿素也会遭破坏,就和留在叶子里的养分或枯萎了的茶褐色混合,这样就变成各种美丽的颜色了所有的树叶中都含有绿色的叶绿素,树木利用叶绿素捕获光能并且在叶子中其他物质的帮助下把光能以糖等化学物质的形式存储起来。除叶绿素外,很多树叶中还含有黄色、橙色以及红色等其他一些色素。虽然这些色素不能像叶绿素一样进行光合作用,但是其中有一些能够把捕获的光能传递给叶绿素。在春天和夏天,叶绿素在叶子中的含量比其他色素要丰富得多,所以叶子呈现出叶绿素的绿色,而看不出其他色素的颜色。当秋天到来时,白天缩短而夜晚延长,这使树木开始落叶。在落叶之前,树木不再像春天和夏天寻样制造大量的叶绿素,并且已有的色素,比如叶绿素,也会逐渐分解。这样,随着叶绿素含量的逐渐减少,其他色素的颜色就会在叶面上渐渐显现出来,于是树叶就呈现出黄、红等颜色。
梧桐树的价值也很大哟。梧桐树为栽培于庭园的观赏树木。木材轻软,为制木匣和乐器的良材。种子炒熟可食用或榨油,油为不干性油。根皮、茎、叶、花、果和种子均可药用,治腹泻、疝气、须发早白,有清热解毒的功效。树皮的纤维洁白,可用以造纸和编绳等。木材刨片可浸出粘液,称刨花,润发。
梧桐子是梧桐树的种子。秋末至冬初采收,除去杂质,晒干。干燥种子,圆球形或类圆形,径6~8mm,黄棕色至深棕色,表面皱缩成网纹状。外层种皮较脆,易破裂,内层种皮坚韧。除去后,内有肥厚的淡黄色胚乳;子叶两片薄而大,紧贴在胚乳上,胚根位于较狭的一端。气、味均微。以个大、饱满、棕色、无杂质者为佳。陶隐居云:“桐树有四种,青桐叶皮青似梧而无子。梧桐色白,叶似青桐而有子,子肥亦可食。”李时珍说:“梧桐处处有之。树似桐而皮青不皵,其木无节直生,理细而性紧。叶似桐而稍小,光滑有尖。其花细蕊,坠下如醭。其荚长三寸许,五片合成,老则裂开如箕,谓之藁鄂。其子缀于藁鄂上,多者五六,少或二三。子大如胡椒,其皮皱。其子,甘平无毒。”
梧桐树就是这样的哟。

昨天,我和爸爸、妈妈兴致勃勃地去爬了梧桐山。
去梧桐山好麻烦呀!一会儿坐地铁,一会儿转公交。经过一个多小时的奔波,终于到达了目的地——梧桐山。
在我看来,远看梧桐山只觉得高,整个山脉全是一片翠绿。当我们看见导游牌是,才知道梧桐山是多么大、广,果然是百闻不如一见。
从泰山涧出发,一路迎着微风,台阶时缓时险,比想象中的的要险多了,不一会儿就气喘吁吁了。泰山涧是梧桐山最早、景色最美、最受市民喜爱的登山道,应该爬起来是很轻松的才对呀!
终于到了溪地了,那里有一个水库,但因为现在是枯水季节,所以没什么水。一路迎着溪流,随着山势。溪流时而宽时而窄,时而缓时而急。溪流缓的地方,有很多人在玩水。因为是枯水季节,所以溪里的岩石都大块大块的裸露出来,我和爸爸就在石头上前进,而妈妈就走登山道。爸爸还说:这条小溪就是深圳河的的源头。还有些地方很难爬,要手脚并用。
爬着爬着,不知不觉中就到了杜鹃长廊和好汉坡。但我们没爬好汉坡,只是留影做了纪念。下山时,我们没走泰山涧,因为从那里下山太险了。我们走的是盘山公路,但是已经禁止普通车通行,所以没那么险。正走着那,可发生了一件趣事——5头牛3大2小。围观的人还不少。我说:它们是野黑牛!但爸爸说:不是!但仔细一看,牛鼻子上都没套牵牛用的铁环,那果真是放养的。爸爸还想摸摸那条大一点的小牛,但还没碰着,小牛就后退了,仿佛在发出警告。我还抄了两条近路,是惊险刺激抓着藤蔓爬下来的。在另一个地方,我们还看见一大群人排着长队一个接一个地抄近路,样子特别好笑,引来一群人在下面围观,我妈妈还拍了照。
路上,我们还看见了几辆消防车、警车、救护车,爸爸开玩笑说:我们跟他们谈谈,搭个顺风车下山?
最后,我们筋疲力尽的回了家。结果打开电视看了第一现场才知道,有人在泰山涧玩水时滚下去死了,难怪这些车会出现在山上。我觉得那个人很可怜,所以登山要非常小心。
梧桐山的登山道很多,不同的人可以选择不同级别的登山道,要越来越小心。我非常想再爬梧桐山。
