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。

我有一辆心爱的小自行车,从三年级起我就每天骑着它去上学,它给我带来了许多的乐趣,在它的陪伴下我一天天长大。
记得我8岁生日那天,爸爸给我买了一辆20型黑色的横梁小自行车作为生日礼物。说它是自行车,其实更像玩具。它油亮的小车身,软软的小车座,我只看了一眼就再也舍不得放下它了。
可是,小自行车好像和我很陌生,试骑时总不听我使唤,车把摇来晃去,我骑在车上就像耍杂技。不好,前方有个排球杆,我左摆右摆,只听“砰”的一声,车头撞了上去,看看碰歪的车把,我心里好难受。
有了这次教训,我不敢再轻易独自骑车,而是请爸爸帮我扶着,这样我渐渐地掌握了骑车的要领,小自行车也终于接受了我这个小主人。
每天放学回家,我都要骑着它兜上几圈,从中体味骑车的快感。小自行车给了我展现技能的机会,使我找到了自信心,获得了极大的满足感。
四年级以后,爸爸妈妈开始让我骑车子上学。这时,小自行车的功能开始变化,它已不再只是一件玩物,还有了实用价值。有了小自行车的帮助,我每天可以独自上学、回家,再也不用爸爸妈妈接送了。每当我挎着书包,骑着车,和大人一样穿行在热闹的公路上,心里就有说不出的喜悦。小自行车给了我独立的意识和成熟的感觉。

大家一定都听说过火龙果吧。
火龙果大概有我的两个拳头大。梅红色的表面十分好看,从远处望去,还真像一团火焰呢!如果你凑近仔细看,会发现火焰里面夹杂着许许多多白白的小点点。梅红色的表皮上长着十几片软软的,像剑一样的鳞片,螺旋形地长着,似乎是一条绕着圈圈的楼梯。鳞片的底下和火龙果的表皮一样,也是梅红的,中间是黄色的。等到了最上面,就完全变成绿色的了。在火龙果的顶部,有一个小洞。在火龙果的底部有三个一簇的小尖刺,扎到手上一定会出血,你可要小心哦。把鼻子凑近,深深吸一口气的话,一股淡淡的青草味扑鼻而来,沁人心脾。
切开一看,火龙果表皮里外的颜色是不一样的,靠果实的那边明显比要靠外的那边深。果肉是白色的,纤维状的,有数不清的黑籽在里面,像黑色的鱼籽酱。挖一勺尝尝,清甜爽口,像加了芝麻的冰淇淋。黑籽滑过舌尖,麻麻的,嚼一下,香脆香脆的真好吃。吃完以后,火龙果就像一只小船,红红的,漂亮极了。用手一挤,边缘里的红汗就流出来了,好像血。
这就是火龙果,你有没有垂涎三尺呢?赶快尝一尝吧!

瓷器是中国的特产,有的瑰丽;有的朴素;有的简约。但都透露出一股中国风。
从夏商周的灰陶、黑陶、红陶、彩陶、白陶、带釉硬陶开始,瓷器就是人们生活中不可缺少的一部分。这仅仅是瓷器发展的开始,到了隋朝时期,瓷器中的青瓷开始烧造,白瓷得到了很好的发展。而当历史的转轮,转向唐朝时,真正的瓷器出现了。这是陶与瓷的分水岭,因为在此之前的陶瓷质地脆弱,只能算作原瓷。
越窑和邢窑也是此时期出现的,在五代十国时期时期,越窑成为吴越王钱氏的御用器皿。并且在此阶段中,天青色出现,获得了「雨过天晴青」的美称。
到了宋朝,定窑、汝窑、官窑、哥窑、钧窑,形制优美,高雅凝重。其程度前无古人,后无来者。
明清两朝,瓷器更是花样百出,万历年间有名的五彩、斗彩、成为后世彩瓷发展的基础,甚至日本伊万里古瓷也是根据这时期的斗彩发展出来,「万历彩」也就在史上成名。同时又有红地黄彩、蓝地黄花、红地青花、黄地青花五彩、描红等等各式彩瓷。
但无论瓷器如何变化,他都是中华民族的一份骄傲!
初恋50 First Dates
What would it feel if I can wake up everyday forgetting what happened for the last whole year?
Lucy in the movie “50 First Dates” told me this feeling. Every morning when she woke up, she only rememberred the Sunday of last year which was her father’s birthday, also the date she had the car accident which made her only keep memory before Sunday, so she always felt happy living the same habit as what she did on Sunday a year ago with the kind set-up by her father and brother. After meeting Hey, she could only remember who he was on the same day. But after one night, he became a stranger to her. She couldn’t even recognize he was the one she used to date and love everyday. Hey tried his best to give her a new different meeting every day so as to win her smile and regain their “First Date”. Hey made her tapes every morning to help her remember what happened the day before and the last whole year. Lucy thus felt grateful with all she had when she woke up everyday. On the same day, she always had the same deep gratitude to face Hey with her sweet smile. What a beautiful feeling it is to always feel thanksgiving and to always
appreciate each other’s effort. A touching story between a memory lost woman and a devoted man taught all of us, normal people, the essence of love. When two people can thank each other for their devotion everyday like what they did for each other on first date, love can forever be refreshed and energetic. On Lucy’s side, people with memory will ask for more than yesterday and become critical of their partners day by day, while people without memory will feel grateful for their life and the people around them everyday.
In the movie, when one day Lucy decided to break up with Hey to let him rebuild his life by burning all their diaries and tapes, I cried for Hey’s broken heart. For her, it was just one day feeling. For him, it was long-term affection and connection. It was easier for her than him to give up their love. On Hey’s side, people with memory will always remember the past happiness and
treasure it for the rest of their life, while people without memory will easily give up at the end of the same day.
What a ruthless feeling it is to end a relationship just after one minute thought. People with fragile mind would easily ruin a long-term relationship no matter what reason they have. The torture between Lucy and Hey tells us the fatal factor to do harm to intimacy between a couple is their fragile mind of
balancing emotion and reason. Thus most of couple lose their trust for each other after experiencing this weakly testing broke-up.

魔术师THE ILLUSIONIST FACTS
When word of the famed Eisenheim's (Ed Norton illusions reaches Crown Prince Leopold (Rufus Sewell, the ruler attends one of the magician's shows in order to debunk the performance. But when the prince's intended, Sophie von Teschen (Jessica Biel, assists the magician onstage, Eisenheim and Sophie recognize each other from their childhoods, and pretty soon they're totally hot for each other. As the clandestine romance continues, the prince's best cop (Paul Giamatti is charged with exposing Eisenheim, even while the magician gains a devoted and vocal public following. Before long, Sophie turns up dead, and the logical suspect is Eisenheim himself.
一线声机"Cellular" has the setup for a solid straight-ahead thriller: A kidnap victim who does not know where she is being held phones a total stranger who must then stay connected on his cell phone to find her before she is killed. Joel Schumacher scored earlier with a similarly phone-themed Larry Cohen story, "Phone Booth." As executed by tone-deaf director David R. Ellis, however, "Cellular" becomes an unintentionally hilarious cousin to Brian de Palma's "Raising Cain" and "Snake Eyes."
Ellis seems to have unwittingly spliced together two different films with
mismatched tones: Kim Basinger as the kidnapee and Jason Statham as the kidnapper occupy the deadly-serious, straight-to-video thriller half, while Chris Evans as the rescuer and William H. Macy as a police officer seem to be in a "Saturday Night Live"-alum action comedy. Nowhere else is the disjointedness in tone more apparent than when Basinger and Evans's performances are placed side-by-side during their conversations: The scenes keep cutting between an overwrought Basinger wringing out every drop of melodrama, while a blissfully inept Evans seems to be channeling a cross between Chris Kattan/Jimmy Fallon and Ben Affleck/Keanu Reeves.
Meanwhile, Ellis pulls out tricks intended to generate thrills and surprises. He throws in out-of-nowhere "shocks," a la "Final Destination"; he throws in
flashbacks; he throws in a gun-blazing Macy in Jerry Bruckheimer action-hero slo-mo; and yet, Ellis has no handle on staging any of them competently. Case in point: "Cellular" is the proud owner of one of the most ineptly scored chase sequences ever, as if Ellis simply heard a snippet of the song's lyrics ("...where you gonna run to?" literally and paid no attention to the inappropriateness of the accompanying music (which just bop, bop, bops along. (The song is even reprised during the closing credits, which itself is misbegotten in conception.
And yet, for all of its failures as art, "Cellular" is always entertaining for those very same faults
