物质跨膜运输的其他实例

1、对矿质元素的吸收

逆相对含量梯度——主动运输

对物质是否吸收以及吸收多少，都是由细胞膜上载体的种类和数量决定。

2、细胞膜是一层选择透过性膜，水分子可以**通过，一些离子和小分子也可以通过，而其他的离子、小分子和大分子则不能通过。

二、比较几组概念

扩散：物质从高浓度到低浓度的运动叫做扩散(扩散与过膜与否无关)

1、(如：O2从浓度高的地方向浓度低的地方运动)

渗透：水分子或其他溶剂分子通过半透膜的扩散又称为渗透

2、(如：细胞的吸水和失水，原生质层相当于半透膜)

半透膜：物质的透过与否取决于半透膜孔隙直径的大小

3、(如：动物膀胱、玻璃纸、肠衣、鸡蛋的卵壳膜等)

选择透过性膜：细胞膜上具有载体，且不同生物的细胞膜上载体种类和数量不同，构成了对不同物质吸收与否和吸收多少的选择性。

(如：细胞膜等各种生物膜)

Dear Tom,

Im sorry for not replying to your e- mail earlier. Last week ,I was so occupied in preparing for the final examination that I even didnt have time to surf the Internet .You know the exam is very important for me.

You asked me about my plan for the summer vacation .Well,there are so many things to do. But as is often the case, the first thing that I want to do is to travel. Not only can travel make me relaxed but also it can widen my horizon and enrich my knowledge by experiencing the countrys language,culture and custom. This summer, the place where I would like to travel is Paris, the capital of France. Apart from travel,I also want to be a volunteer .I want to help the children, whose parents went to big cities to make a fortune but left their children living with their grandparents. What about your summer vacation? Looking forward to your reply.

Yours

辽阔苍穹中飞翔的老鹰，必是经历了母鹰无数次摔下山崖的痛苦，才锤炼出一双凌空的翅膀。

一颗璀璨无比的珍珠，必然经受过蚌的肉体无数次蠕动以及无数风浪的打磨，才能熠熠生辉。

同样，一个真正有成就的人，也肯定是在无数次的跌倒后重新站起来的，因为“不经历风雨，怎能见彩虹?没有人能随随便便成功”。

史铁生摔了一跤，没有了双腿，这对任何人来说都是沉重的打击。但他没有因此对生活失去信心，而是用自己的大脑和双手去表达对生活的无限热爱。

贝多芬双目失明且耳聋，但他依然写出了《英雄》《命运》等大量音乐作品，在人生的不幸中，他顽强地扼住了“命运的咽喉”。

这些都是曾经摔过跤的人，但他们却都坚强地站了起来，与命运、与不幸抗争，最终取得了巨大的成功。

所以对我们每个人来说，摔跤并不可怕，可怕的是你从此对生活失去信心和勇气。

冰心说：“成功的花，人们只惊慕它现时的明艳!然而当初它的芽儿，浸透了奋斗的泪泉，洒遍了牺牲的血雨。”

所以我们每个人面对不幸时都不能一蹶不振，因为我们都有可能在改变心态后，握住生命的任何一根链条。

就像画中那个男孩在摔跤后，面对来自老师、家长、社会各方面的询问，我们都应大胆地说：“这没什么大不了的。”

因为生活是我们自己的，命运是掌握在我们自己手中的，我们的心态、我们的选择，决定了人生的方向。

挫折是人生的一笔财富，是促使你成功的一剂良药，不经历风雨的花儿，怎么会绚烂?不经历磨难的人生，怎么会发出炫目的光彩?

就像2005年感动中国的人物——洪战辉所说：困难，我们有责任去面对它，解决它。作为新一代的年轻人，我们应该明白摔跤并不可怕，就像我们总是有勇气唱起这首歌：不经历风雨，怎能见彩虹?没有人能随随便便成功!

我要说，不经历一次次摔跤和一次次跌倒后又站起，人怎么能长大?摔跤也是一种幸福，风雨正是雨后彩虹的前兆!

From where I stand ， I am not in favor of encouraging kids with cash just because they have got good marks 。

My parents used to encourage me like this。 Whenever I made progress in studies ， they bought me my favorite books ，which not only motivated me to learn ，but also helped me get along well with my studies。

To get kids motivated to learn ， I think we should not treat every child in the same way。 To some students ， oral praise is essential 。 Don’t save the praise for only the top score。 If possible， involved other *s in praising them 。 However， this method may not work well with other kids。 Maybe what is more important to them is to water a movie or go on a trip together with their parents 。 It just depends。

In recent years, extravagance and waste have become increasingly serious in some of the university campus. We can see that papers, bottles and cans are thrown away after use; food is wasted just because of its poor taste; clothes are discarded simply owing to their old fashion. As a consequence, people in mounting numbers put great emphasis on creating a green campus.

There are at least two criteria to distinguish what is green campus. On the one hand, natural resources must be conserved and made full use of, for example, we, as college students, should take the wise use of papers and second-hand textbooks into account. On the other hand, education to build up thrift habits must be promoted by relevant departments and professionals at various levels.

Accordingly, it is necessary for us to take effective steps. For one thing, university authorities should respond with the demand for more rigid conservation of our natural resources, such as water, electricity, and so on. For another, we should enhance the awareness of college students that creating a green campus is of utmost significance to both our society and ourselves.
