These eggs will then hatch inside the unwilling adoptive mother's mouth, and proceed to eat the cichlid eggs present before being released by the cichlid.

2：换个题目吧，讲些其他的东西，换个小的lecture，这样就可以换个小的教室啦，不用担心empty6：生物的，保持体温的2类方法

It did not lead him to meditate upon his frailty as a creature of temperature, and upon man's frailty in general, able only to live within certain narrow limits of heat and cold; and from there on it did not lead him to the conjectural field of immortality and man's place in the universe.

这不会是他开始沉思自己作为一种有体温的生物的脆弱性，人类一般只能在一定冷热限度内生存的脆弱性；这也不会使他考虑关于不朽和人类在宇宙中的位置之类的问题。

The glaciers, perhaps 200 million years old, also may entomb genetic fragments of past microbial life on Mars as well as air bubbles that might reveal the composition of the atmosphere as it was long ago, according to geologist James Head of BrownUniversity in Providence, Rhode Island.

根据 Rhode Island 州 Providence 大学地理学家 James Head of Brown 的说法，这块大约有2亿年的冰河可能会藏有火星过去生物的基因碎片，也可能会有一些气泡。这些气泡里的空气会表明多年以前火星大气的成分。

International forest canopy networks have been established worldwide. To understand the relationship among community characteristics, environmental factors and epiphyte dynamics, and develop effective and standard methods and technologies for the study of forest canopies, more work is needed in this field.

由于世界各地森林类型多样和环境条件各异，目前国际上有关附生物的研究仍十分活跃，建立了林冠研究网络，研究不同类型森林中附生植物及其枯死残留物的动态及其与群落特征、环境因子的数量关系，探讨、交流和发展有效的标准测量方法和技术是该领域研究的主要内容。

In the past, studies have been concentrated on some of the pathogenic bacteria due to the diversity of oral organisms, complexity of ecological environment and limitation of research methods. Few research was involved in the change and gene expression of microbial population and role of functional protein in the matrix of dental plaques in the pathogenesis and development of disease.

由于口腔生物的多样性、生态环境的复杂性以及研究方法的局限性，以往研究大多集中于部分致病菌；对于菌群在疾病发生、发展过程中的整体性变迁及其基因表达、菌斑基质中功能性蛋白质分子作用的研究甚少。

To understand the impact of plant canopy photosynthate inputs on soil nematode communities, a large-scale tree girdling experiment was conducted in a evergreen broad-leaved forest of Ailao Mountains.

3为了解植物光合产物通过根系实现的地下资源输入对土壤生物的影响，本研究通过大规模的环割实验切断植物向地下运输光合作用产物的通道，研究了环割前后土壤微生物生物量、土壤线虫密度和多样性的变化。

Moreover, we illustrated the method by examining similarity or dissimilarity of exon-1 ofβ-globin gene of 11 species, and compared our results with some existing results of other methods.

以11种生物的β-globin基因的第一外显子为例分析了序列间的相似性，并同其它文献中的相似性分析的结果进行了比较。

Constructed wetlands are artificial wastewater treatment systems which contain physical, chemical and biological process in the ecosystem, and treat wastewater efficiently according to filtration, absorption, deposition, hydronium exchange, as well as microbe decomposition.

人工湿地是，是由人工建造、监督和控制的，它充分利用湿地系统净化污水能力的特点，利用生态系统中的物理、化学和生物的三重协同作用，通过过滤、吸附、沉淀、离子交换、植物吸收和微生物分解来实现对污水的高效净化。

He compared the evolution of knowledge with the proliferation of biological specialties, then the progress of science now finds its expression in theproliferation of disciplines, and the incommensurability was the necessary mechanism of the development of scientific knowledge.

他把知识的进化类比为生物的进化，把科学的进步理解为学科的增多，而不可通约性为学科的增殖提供了先决机制。

For almost 90 percent of its history the planet has been inhabited, and shaped by life.

在地球存在的差不多90%的时间里，都有生物的存在，而且它们在地球上的生活不断改变着地球的面貌。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
