大意翻译如下：
Walking on the streets,has anyone been curious about the origins of the names of the places in Taiyuan City,for example,the names of some road,some street,some alleyway and some building which we are quite familiar with?I think we can learn a lot about the history of Taiyuan City from those names by studying their origins.I have written an article about the names of the places in Taiyuan City,telling how the names emerged,to introduce the history and culture of Taiyuan City.
The famous "Weeping Willow Alleyway"
Zhu Yuanzhang,the first emperor of Ming Dynasty(1368-1644),ordered his men to battle the Yuan(1206-1368) army in north.His aim was to destroy the enemy's millitary center -- the old Taiyuan City.Taiyuan City had a high city wall and a deep city moat at that time,which provided the Yuan army with good protection and also caused the Yuan army to be relaxed.The Ming army general Chang Yuchun disguised himself as a woodman and went into the Taiyuan City in order to know more about the enemy.What was beyond expection was that Chang Yuchun was dicovered by the enemy for he had been traced by a Yuan spy.Hardly had he walked across the Qiaotou Street outside the east gate of the old Taiyuan City and gone into the Zhaoxi Gate(the city gate) when the Yuan soilders came to surround him.General Chang fought with the soilders,escaped and ran into a alleyway below the city wall.He hid himself in a humble yard in the alleyway.
In this humble yard lived an elderly widdow whose surname was Liu.(Liu is also the name of weeping willow in Chinese) Liu's husband had beed killed by the Yuan army years ago.Her son had also been caught by the Yuan army and never returned.She hated the ruler of the Yuan Dynasty so much.When Liu saw the woodman was chased by the Yuan soilders,she really had symphathy for him.She hid Chang Yuchun,the general,in the piles of wood in the backyard before the Yuan soilders came and then she pretended to be deaf and dumb and tricked the soilders.
General Chang was saved.He was truely grateful to the elderly lady for saving his life.Before he left,he picked a branch of the weeping willow growing in the yard and gave it to Liu and said,"Old mama,war is coming.Attach this on the front door and the Ming soilders will try their best to protect you."
A few days later,the Ming army began to attack the Taiyuan City just as what the general had said.Liu saw the war breaking out.She was worried about her neighbours; therefore,she told them to attach a branch of weeping willow on their doors.Soon,the Ming army got the charge of the whole city because general Chang had known the details of the enemy and had arranged some people inside the city.When the Ming soilders went into the city,they followed the general's order to protect the citizens who had a branch of weeping willow on their doors.
After the war,the neighbours thanked Liu a lot.In order to mark the renascence of Taiyuan City,the neighbours put the branches into the soil.The branches grew up as time passed by.Year after year,weeping willows stand in the alleyway and become green in the right season.They have beautiful figures and bring shadows to people there.Because of this,the alleyway got a beautiful name "weeping willow alleyway".
分析：
1、the names of some road,some street,some alleyway and some building这里的很多个some都表示“某个”的意思,后面跟单数名词.
2、“先说众所周知的柳巷”这句话在译文中作为一个小标题译出.
3、“柳巷”的翻译.“柳”在这里有两个所指,一指柳氏,二指巷中的柳,所以在翻译时既可以翻译成“Weeping Willow Alleyway”又可以翻译成“Liu Alleyway”.但是根据故事内容,我认为要翻译成前者,因为主要还是因为巷中的美丽柳影才使小巷得名的.
4、翻译时如果遇到朝代,要标出其年份,如Ming Dynasty(1368-1644)等等.
5、In this humble yard lived an elderly widdow whose surname was Liu.(Liu is also the name of weeping willow in Chinese)注意这里括号中的补充说明.
6、柳氏在文章中经常是主语,所以直接用Liu来指代她,如第四节所示.

组成细胞的最基本元素是C ；基本元素C、H、O、N；主要元素是C、H、O、N、P、S；大量元素是C、H、O、N、P、S、K、Ca、Mg．在高中阶段一定要分清元素的分类．

水有源,故其流不穷；木有根,故其生不穷.两句话的意思是说办事要开源固本,才能求得不断发展,看问题要追根溯源,才能抓住本质.

因为生物体是有选择地从无机自然界获取各种物质组成自身.

应该选C吧

1细胞是有选择的吸收元素的,所以元素比例与外界不同,如果还要追根溯源的问为什么这个比例是这样的,那只能说是细胞经过长期进化自己变成这样的
2不能,生命系统的最低级是细胞,细胞是一个有序的生命体,配齐了物质没有细胞膜把它们包起来,不能形成细胞,即使有了细胞膜,里面的物质没有形成有序的生命活动,那也不是细胞

组成细胞的元素追根溯源来自无机环境,这是因为生物界与自然界存在着统一性,细胞内各元种素的比例与环境的不大相同,是因为它们之间存在差异性.

我记得书上细胞膜那章好像有答案...
因为细胞膜有选择透过性,可以将细胞需要的物质转运入胞内,而将不需要甚至有害的物质阻隔在胞外,使细胞可以正常进行生命活动

解题思路：根据光合作用的定义分析解答．

绿色植物通过叶绿体利用光能把二氧化碳和水合成有机物，并储存能量，同时释放出氧气的过程叫光合作用．光合作用实现了能量转化，把光能转化为储存在有机物中的能量，因此线粒体中有机物分解所释放的能量的最终源头时光能．
故选C．

点评：
本题考点： 光合作用过程中的物质转化和能量转化．

考点点评： 熟悉光合作用的定义就可做好此题．
