Valero, America's biggest oil refiner, has bought up troubled ethanol plants and invested in firms that use plant material, algae and rubbish to produce fuel.

美国最大的炼油公司，瓦莱罗能源，买下了一些有经营困难的乙醇厂，也投资了将植物原料、藻类、和废弃物转化成燃料的公司。

Tilapia is the dominant species in most lakes of South China, and its food includes phytoplankton in open water habitats and periphyton in substrate-surface habitats.

罗非鱼是我国南方很多水体的优势种，食物包括敞水生境的浮游植物和基质表层生境的附着藻类等。

The main conclusions were summarized as follows,(1)Filamentous periphyton in the wastewater treatment system showed nitrogen and phosphorus removal efficiency,and the average removal rates of NH_4~+-N,NO_3~--N,TN,PO_4~(3-)P and TP reached 60.5%, 52.4%,68.4%,71.9%and 74.0%,respectively.

研究结果主要体现在以下几方面：(1)丝状周丛藻类对水体中的氮、磷均具有显著的去除效果，对NH_4~+-N、NO_3~--N、TN、PO_4~(3-)-P和TP的平均去除率分别达60.5%、52.4%、68.4%、71.9%和74.0%。

5Under SE medium conditions,unicellular periphyton had significant absorption effect on nitrogen,nutrient the average removal rate for TN and NH_4~+-N could reach above 20%,while NO_3-N increased, and the phosphorus absorption rate was still low(＜10%).

5培养液条件下，颗粒态周丛藻类表现出显著的氮营养物吸收效果，TN和NH_4~+-N的平均去除率均可达20%以上，NO_3~--N略有增长，而对磷营养的吸收率仍较低(＜10%)。

In the red beds of the Mesozoic Era Nanxiong Late Cretaceous to Cenozoic Paleocene strata, the unearthed, including gastropods, ostracods insects, wheel types such as algae and dinosaur fossils were more than 60 genera, 110 species, of which the most abundant dinosaur fossils, there is Tyrannosaurus rex, short spines Nanshiungosaurus, Nanxiong Microhadrosaurus, as well as fossilized dinosaur eggs into the nest.

在南雄红层的中生代晚白垩世至新生代古新世的地层里，出土了包括腹足类、介形虫类、轮藻类和恐龙类等古生物化石共60 余属、110种，其中以恐龙化石最为丰富，有霸王龙、短棘南雄龙、南雄小鸭嘴龙以及成窝的恐龙蛋化石。

Some form symbiotic associations with algae or cyanobacteria to form lichens, while others form extremely important mycorrhizae with the roots of many plants, including most forest trees.

真菌是土壤和淡水中主要的分解者，一些与藻类或蓝细菌共生形成地衣，还有一些真菌与许多植物包括大多数林木的根形成大量的菌根。

Clearly, Volvox evolved from similar algae that exist only as single cells, but until now the genetics of the process have been obscure.

毫无疑问团藻是由类似的只以单细胞形式存在的藻类进化而来，但直到现在这一过程的遗传学原理依然模糊不清。

One creature that has managed the trick—separately from plants, animals and fungi, who are the real experts in the field—is an alga called Volvox carteri.

有一种生物成功做到了这些，它们是从植物、动物和真菌中分离出来的这一领域的真正专家——一种叫团藻Volvox carteri的藻类。

In most instances, red and green algae have lower contents, about 100-300 ppm in dried seaweeds, but remain high in comparison to any land plants.

在大多数情况下，红色和绿色的藻类含量较低，约在100-300 ppm的干海藻，但仍比任何陆地上的植物高。

To others, it's the world they live in: a boundary zone flooded with light, which is why they are countless green algae floating around here.

而对于生活在这里的生物，这是一个充满了阳光的分界地带，无数的藻类生活在此。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
