第一单元：动物的外形及功能。主要内容包含营养及消化、呼吸系统、循环系统、免疫系统、渗透调节及排泄系统、内分泌系统、生殖及胚胎发育和神经系统。

Given this assumption, even if the parameters of the system are randomly perturbed, by either genetic mutation, environmental variance or experimental manipulation during development, the system will generate a limited and discrete subset of phenotypes. Thus the realm of possible forms is a property of the internal structure of the system.

而在这种假设的前提下，即使系统各参数值受到发育过程中的随机扰动（或者是遗传突变，或者是环境变化或人工实验操纵），系统会产生出某个某个有限的、离散的表型[11]子集，因此，生物可能形态的王国，其疆域从属于生命系统的内在结构。

In order to understand and know about the basic principle and quantification relationship of greenhouse phalaenopsis during vegetating phase and forecast the dynamic action of vegetation system so as to assist reasonably regulating and controlling on the vegetation and production system of phalaehopsis real time, a dynamic vegetation model of greenhouse Phalaenopsis is created on the solar radiation as the basic driving factor and a computer simulation system is developed on Windows XP system.

为了对温室蝴蝶兰生育过程的基本规律和量化关系有一个清楚的理解和认识，并对其生长系统的动态行为进行预测，从而辅助进行对蝴蝶兰生长和生产系统的适时合理调控，研究建立了以太阳辐射为基本驱动因子的温室蝴蝶兰生长发育动态模型，进一步开发出基于WindowsXP的计算机模拟系统。

This thesis has systematically dealt with the glacial, lake and climatic fluctuations in the areas mentioned above throughout the late stadial of the Last Glaciation, based on synthetical records of glacial development at the high mountains, lacustrine stratigraphy and lake evolution in both the high plateau basins and the lower altitude interior ones, periglacial phenomena and palaeosols as well as microfossils in deposits.

本文则根据大量野外实地考察与室内分析资料，从高原高山区的冰川发育与演化，高原和盆地区的湖相沉积地层、湖泊演变历史和地层中冰缘现象、古土壤的发育状况以及微体古生物等方面的综合记录分析，对青藏高原北部与天山地区以及内陆干旱盆地在末次冰期晚阶段中的冰川、湖泊与气候环境演变状况作了较为系统的探讨。

本文以单胚水稻IR36作为对照，系统观察了多胚水稻品系APⅣ的胚胎发生过程，包括胚囊的形成、发育、受精及其胚胎发育；。。。

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。
