藻类

Here bulrushes filter and treat waste products added by waterfowl and algal production in the deep pool.

这里的芦苇过滤和对待废品、藻类产量增加了水禽深池。

Across the country, millions of tons of raw sewage, industrial waste and fertilizer runoff have turned lakes into algae-covered cesspools.

在全国许多地方，大量未经处理的污水、工业废水以及含有化肥残留的农田用水把众多湖泊变成了污水池，大片水面被藻类所覆盖。

All this comes as China grapples with a mounting water shortage. Across the country, millions of tons of raw sewage, industrial waste and fertilizer runoff have turned lakes into algae-covered cesspools. According to official statistics, more than half of China''s major waterways are so polluted that fish are dying or water is unsafe for drinking or irrigation. More than 300 million people -- almost one-quarter of the population -- lack access to clean drinking water, the government says.

所有这些问题都是在中国水资源日益短缺的大背景下出现的在全国许多地方，大量未经处理的污水、工业废水以及含有化肥残留的农田用水把众多湖泊变成了污水池，大片水面被藻类所覆盖从官方的统计数字看，中国一半以上主要河流的污染程度已经严重到了鱼虾绝迹或河水已无法供饮用和灌溉之用的程度

The scientists say the lost of different kindd of sea life appeared to increase the risk of fish kills and beach closers from harmful alge growth.

科学家说，失去不同kindd海上生活似乎增加患鼓滩死鱼和有害藻类生长。

After metal exposure (at PFD 35 mmol m-2 s-1 and temperature 21±1 8℃), algal samples were withdrawn, separated from the medium by filtration on a Whatman GF/C filter, washed with deionised water and extracted for thiol peptide analysis.

在金属接触（在光强35浓度 m-2 s-1和温度21 ±1 8℃），藻类样品被撤回，脱离介质过滤的瓦特曼石墨/碳过滤器，洗涤水和提取deionised为硫醇多肽分析。

In particular, they are interested in the fate of diatoms.

他们对矽藻类的命运尤其感兴趣。

The crucial question is what happens to these diatoms when they die.

问题的关键是当这些藻类死了的时候它们本身发生了什么变化。

Seen here 400 times their true size, diatoms are a type of algae found in oceans, fresh water, and soil.

这里是放大400倍的真实尺寸，硅藻属是一种典型藻类可以在海洋，新鲜的水中，土壤里找到。

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.
