植物作为初级生产者是生态系统的核心，水生植被的存在是博湖长期保持淡水特色的主要原因之一，当水面上有水生植物生长时，湖面的蒸发蒸腾量低于自由水面的蒸发量，从而降低了水体的矿化度并净化了水体。

After this Stop we made on to the Southward continually for ten or twelve Days, living very sparing on our Provisions, which began to abate very much, and going no oftner into the Shoar than we were oblig'd to for fresh Water; my Design in this was to make the River Gambia or Sennegall, It is to say, any where about the Cape de Verd, where I was in hopes to meet with some European Ship, and if I did not, I knew not what Course I had to take, but to seek out for the Islands, or perish there among the Negroes.

这次停船之后，我们向南一连行驶了十一二天，我们的粮食逐渐减少，只得省着点吃。除了取淡水不得不上岸外，很少靠岸。我这样做的目的是要把船驶到非洲海岸的冈比亚河或塞内加尔河；也就是说，到达佛得海角一带，希望能在那儿遇上欧洲的商船。万一遇不到的话，我就不知道该往哪儿去了。那就只好去找找那些群岛，或者死在黑人手里了。

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.
