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。
A review of the Pursuit of Happiness
“The Pursuit of Happyness” was released on the 15th of December 2006. It is a dramatic story based on a biography of Chris Gardner’s nearly one-year struggle with homelessness. Directed by Gabrielle Muccino, the film stars Will Smith as Chris Gardner, and co-stars Jaden Smith playing Chris’ son, Christopher Jr. For Will Smith’s performance in the film, he was nominated for an Academy Award and a Golden Globe for Best Actor. The ‘different’ spelling of the title, ‘Happyness’ is seen by Chris Gardner on the building outside the play centre is son attends, which Chris reminds the owners of the building multiple times that it is spelt with an ‘I’.
The film shows us the struggles Chris Gardner has with homelessness. He is bankrupt because he invested his life savings in portable bone-density scanners, which he thought hospitals would be interested in buying, but in the end hardly any doctors wanted one, as they considered it an ‘expensive luxury’. During the struggles, his wife Linda leaves to go to New York and Chris and his son are left in San Francisco with no income and living in a motel. Chris sees interest in become a stockbroker, but to become one he has to go through an internship. Meanwhile, Chris and his son are evicted because they can’t pay rent, and they are forced to go to a homeless shelter, and even one night had to sleep in the bathroom of the underground rail system. During his internship, he never once mentions his financial struggles and at one point he is asked to give one of his bosses 5 dollars for a cab, a sum that he can’t afford. After an intense six months, Chris is taken into the bosses’ office, and is offered a job as a stockbroker, the final scene shows him being in unbelief of the position he was offered and showing his happiness and gratefulness for the opportunity, Chris realises that his financial struggles are over as he now has a job with a regular income.
Christ was unfortunate, for he got a wife who was not understandable at all (though she has her own difficulties and was in bad luck with his business. But he was very fortunate also, for he got a son who was very thoughtful and, I think, tough life experiences always make a great person. It is said that this movie is inspired by a true story, and I want to say, this movie does inspire me a lot. What impressed me most are: Christ’s wife left him because of life pressure; Christ’s love to his son and Christ’s strong belief towards life. Through these, I know that it is not easy to be a good husband and a good Papa, since in reality, only love cannot only make everything. And I also learn that one has to strongly believe in himself, no matter how difficult the situation is, but of course, hard-working is indispensable.
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
