淡水生物

Therefore, these new discoveries have drawn increasing efforts worldwide to study the biology and biomineralization of sponge spicules and their bionic applications.

海绵是生长在海洋或淡水环境中的一种最简单的多细胞生物，3个主要海绵纲中有2个纲的海绵其主要骨架与支撑是玻璃纤维状的硅质骨针。

A hungry Buddhist won't feel happy when served a world-known Peking roasted duck, because that's not what he wants. What he wants is probably two steamed breads and a dish of fried bean sprouts. An old man living alone in the country often receives money and parcels from his son in the city, which is envied by the neighbours. However, what he really wants is to spend his time with his family. A solitary traveler who?hurries on his way under the scorching sun needs nothing so badly but a shelter from a tree, a gust of cooling wind, a palm-leaf fan or the mouth of a spring instead of an expensive fur coat. Far out at sea, where there are not only rich resources that feed all kinds of creatures but also numerous treasures and enormous wealth, a sailor may urgently need some ordinary fresh water only.

一个吃斋念佛的饥饿的人，面对着驰名中外的北京烤鸭，是不会有幸福感的，因为那不是他需要的，他急需的，可能只是两个馒头，一盘素炒豆芽而已；独自住在乡下的老人，总是能收到城里儿子寄来的钱物，很让乡亲们羡慕，但老人最想要的不是这些，而是儿孙膝下承欢的天伦之乐；在炎炎烈日下赶路的人，急需的是一片树阴，一阵凉风，一把扇子，一眼清凉的泉水，而不是一件名贵的貂皮大衣；大海是富饶的，它哺养了各种各样的生物，珍藏着无数的宝藏和财富，但在海上远航的人，急需的却是普普通通的淡水。

As an intersection spot of rivers and coasts, estuary contains both flood and sediments from rivers and threat of marine storm wave and saline-alkali injury. But it is a crossing place of fresh water and salt water, bringing us limitless life and rich nutrition, which has formed manifold bio-resources such as crab and sea eel fry etc.

河口是江河和海岸的交会处，它既有江河带来的洪水和泥沙，又受到海洋风暴潮和咸水盐碱化的威胁，又是淡水、咸水交会处，带来无限生机和丰富的营养，由此形成多种生物资源。

Of the rich biodiversity found here, perhaps no animal is more of an icon of the Amazon than the pink river dolphin, or boto. Its vivid pink color is a display of the male's maturity, something to show off like antlers of a deer.

在当地发现的丰富多样生物之中，堪称亚马逊头号代表的是粉红淡水豚，俗称波托，亮粉红体色是成年雄豚的象徵，跟公鹿的角一样做为自我展现。

There are boat races, the annual Shipwrights' Ball and many more events.

这种生物叫做玛林提，具有40英尺游泳速度，能够离开水面存活一段时间，对淡水及光线过敏。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
