The four types of sustainability include human, economic, social, andenvironmental. All four are required to maintain the entirety of life on Earth. Althoughinterconnected, itis importanttonotethedifferences of eachinterms ofits nature and requirements.The very basic need of humansustainability is good reproductive healthandsafe childbearing.Those that reproduce have the responsibility of caring for their children, giving them access to proper education, and promoting their health and wellness. At some point, the childrenshould have enoughskills and knowledge suchthatthey cansustaintheir ownway of life. Itis atthatpointthatthey becomeconsidered as productive human capital as well as individuals that can go through the process of reproduction and rearing. As long as this process is maintained at a rate that all human systems can support, human sustainability should be no cause for concern.Insimple terms, economic sustainability is havinga set amount of capital for acertain period. Those who consume that capital must also conserve it so that they will continue to enjoy it towards the end of the specified period. This means thatwe must preserve all our resources as we consume them so that human beings inthe future can enjoy them as well. To achieve this, we must regenerate our resources at a rate that is equal to or faster than our consumption.Social capital is an important aspect of sustainability because it is through communities and civil societies that humankind can easily and inexpensively work together. Without proper levels of social capital, it can easily deplete and violence as well as mistrustcantake over. Whenthathappens, societies andeverythingelsethat depends on them will be destroyed. Through proper maintenance of and adherencetolaws, rules, andvalues thatsocieties havedevelopedfor thecommongood, social sustainability can be achieved.Environmental sustainability is important because it involves natural resources that humanbeings need for economic or manufactured capital. Materials takenfromnature are usedfor solutions that address humanneeds. If nature is depletedfaster than it can regenerate, human beings will be left without raw materials.Furthermore,environmental sustainability also involves ensuring that waste emissions areatvolumes thatnaturecanhandle. If not, all humans andother livingthings on Earth can be harmed to the point of extinction.可持续性分类四种可持续性包括人类可持续性，经济可持续性，社会可持续性和环境可持续性。

翻译技巧第九节被动语态的译法英汉对比研究表明，英语中被动语态的使用极为普遍，尤其是以科技英语为主。

这是英语区别于汉语的显著特点之一。

在英语中，大凡为了强调受事，以突出其鲜明位置，而无需提及主动者、无意点明主动者、无从说出主动者，为了上下文的衔接与连贯等等，或是出于礼貌措辞圆通等方面的考虑不愿说出动作的执行者是谁的，往往都采用被动语态。

例如：(1)When will we be interviewed?我们什么时候来参加面试呢?(2)New British and American films are often shown to English major juniors.常给英语专业的三年级的同学放映新的英美电影。

(3)The happy man cannot be harried.吉人自有天相。

(4)You are cordially invited to a dinner party to be given at the Workers’ Club in Xidan at 7 P. m.Nov. 23.谨定于11月23日晚上7时在西单工人俱乐部举行晚宴，敬请光临。

(5)The plan was especially supported by those who wished to have more chance to speak French. 这个计划特别受到愿多有机会说法语的人的支持。

在英语中，被动结构能给人以间接、客观的印象，因而在科技文献、政论文和新闻报道等文体中使用尤为频繁。

相比之下，被动语句在汉语中的使用范围小得多。

主要原因在于，在历史上，汉语被动语句主要用来表达对主语来说是如意或不希望发生的事情。

现代汉语的这种限制虽然在西方语言的影响下有所动，被动句式有时也用来表达中性甚至希冀之事，但是汉语采用的主要是语义型句式，大多数被动意义并不一定非得通过被动语句来表达，而可以通过形式上主动、语义上被动的句式予以体现。
