其实这是53，43和33的区别。我负责任的讲国内生物大概是在1990年代才在中学才开的。而且早期课本主要是普及进化论，没有很多纲目分类概念，我100%确定我当年的课上没讲竹子是草

我很负责任的说，至少80年代中期初一初二初三的生物课就是植物学动物学和生理卫生。动物学一开始就强调分类学门纲目科属种。植物分类主要依据是生殖器官，包括花和种子，与根茎叶无太大关系。动物学从低等动物到高等动物更是按照门来的，因为动物界的门很多，植物界的门很少。赖美豪中 写了： 2025年 4月 20日 18:33 其实这是53，43和33的区别。我负责任的讲国内生物大概是在1990年代才在中学才开的。而且早期课本主要是普及进化论，没有很多纲目分类概念，我100%确定我当年的课上没讲竹子是草

大部分植物门类都是无性生殖没有花和果实。真根也不是一开始就有的。这两点都是中学植物学的内容。所以你这说法也不是太负责任。LightFast 写了： 2025年 4月 20日 18:54 我很负责任的说，至少80年代中期初一初二初三的生物课就是植物学动物学和生理卫生。动物学一开始就强调分类学门纲目科属种。植物分类主要依据是生殖器官，包括花和种子，与根茎叶无太大关系。动物学从低等动物到高等动物更是按照门来的，因为动物界的门很多，植物界的门很少。
不过同意国内教材对门纲目划分很细致。

所以你认为我这说法也是不负责任，但是”不是太不负责任“。这种说法不是我发明的，是教材上明确说的。不过我把种子和果实搞错了。但是生殖器官没说错。tdm 写了： 2025年 4月 20日 20:14 大部分植物门类都是无性生殖没有花和果实。真根也不是一开始就有的。这两点都是中学植物学的内容。所以你这说法也不是太不负责任。

严谨精神。我觉得生殖器官特征可作为种子植物细分标准。而低等植物还是以根茎叶为主因为没有明显的生殖器官。比如苔藓无真根，直到蕨类才有。

动植物分类学好几百年了，本来就是经验式的，有些分类还经常会变。用花和果实分类都是传统的标准，不一定绝对准确，不能涵盖所有范围。现在有了分子生物学，用DNA来分类应该更准确了。

LESSON 2 THE TALLEST GRASS
Did you ever see grass growing high as a tree - a tall tree? Bamboo is this kind of grass. It grows up straight and thin with branches at the top.
Although bamboo is really a kind of grass, it looks more like a tree - a beautiful tree. It has long leaves that sway in the wind like slim fingers reaching to touch something. Chinese and Japanese poets write poems and songs about bamboo, and artists paint it in pictures.
Not all bamboo grows tall. Altogether there are more than 500 different kinds of bamboo, and some grow no higher than your ankles. Bamboo grows best in places where it is warm and where it rains often. Some kinds of bamboo grow very fast. If they are growing near a house, their slim leaves brush the roof gently and cool the house with their shade.
Some bloom and have seeds every year. Some never bloom at all. Some bloom only once, after living about forty years, and then die. However, new shoots of bamboo will come up from around the roots of the old ones.
But the most interesting things about this remarkable plant is what people do with it after it is cut down. Bamboo probably has more uses than any other plant in the world.
Bamboo is not a tree, remember, so the long straight stems of bamboo are not like tree wood. They are hollow, which make them very light. You can lift a big piece of bamboo with one hand. At the same time, bamboo is so strong that people use it to build houses and even high bridges over rivers.
In warm countries, many people have their houses made almost entirely of bamboo: the walls, the roof, the floor. Nearly everything within their houses is made of bamboo, too. The chairs, tables, curtains, cooking pots, flower vases, drinking cups, birdcages, and so on are all made of bamboo. And the fence around their garden is made of bamboo too.
Some bamboo is thinner than your little finger. Some is much thicker than your waist. And because it is hollow, it can be fitted together and used for pipes to carry water. Many farmers' fields are irrigated by water brought from a river or lake through bamboo pipes.
Bamboo is used for more than building. People eat it. The tender young shoots of bamboo are crisp and tasty. They are often found in Chinese or Japanese dishes. Some are put into cans and shipped all over the world.
Bamboo is also made into paper. The soft pulp inside the hard stems is taken out and sent to a factory. There it is made into a fine paper. Bamboo can also be made into good walking sticks and fishing poles.
Who can tell what new use someone may find for this special kind of grass - bamboo?
