　　One basic weakness in a conservation system based wholly on economic motives is that most members of the land community have no economic value. Yet these creatures are members of the biotic community and, if its stability depends on its inteyrity, they are entitled to continuance。

　　When one of these noneconomic categories is threatened and, if we happen to love it we invent excuses to give it economic importance. At the beginning of century songbiras were supposed to be disappearing. 46)Scientists jumped to the rescue with some distimctly shaky evidence to the effect that insects would eat us up of birds failed to control them. The evideuce had to be economic in order to be valid。

　　It is pamful to read these round about accounts today.We have no land ethic yet, 47)but we have at least drawn near the point of admitting that birds should continue as a matter of intrinsic right, regardless of the presence or absence of economic advantage to us。

　　A parallel situation exists in respect of predatory mammals and fish-eating birds. 48)Time was when biologists somewhat overworked the evidence that these creatures preserve the health of game by killing the physically weak, or that they prey only on “worthless species。

　　Some species of tree have been read out of the party by economics-minded foresters because they grow too slowly or have too low a sale value to pay as timber crops. 49)In europe, where forestry is ecologically more advanced, the non-commercial tree species are recognized as members of native forest community, to be preserved as such ,within reason。

　　To sum up:a system of conservation based solely on economic self-interest is hopelessly lopsided. 50)It tends to ignore, and thus eventually to eliminate, many elements in the land community that lack commercial value, but that are essential to its healthy functioning. It assumes, falsely, I think, that the economic parts of the biotic clock will function without the uneconomic parts, It tends to relegate to government many functions eventually too large, too complex, or too widely dispersed to be performed by government。

　　分析：

　　1.整个句子的主干结构是scientists jumped to the rescue，这里有一个很生动的动词jumped，直接翻译的意思是“跳着”，引申为“赶紧，急忙，迅速采取行动”。Rescue是“救援，援助”的意思，所以，即使同学们不知道“to the rescue”本身是一个习惯用法也知道怎么翻译：科学家们急忙来挽救这种局面；或者翻译为，科学家们迅速赶来救援。

　　2.With some distinctly shaky evidence是介词短语作状语，其中有一个比较核心的宾语词evidence(证据)，这个单词在考研翻译20来中考过两次，分别出现在95年73题和99年的73题。所以介词with应该翻译为“用，使用”，因为下文宾语是“证据”，所以是“使用证据”，最好不要翻译为“带着证据”。而evidence前面的修饰语distinctly这个词，是“清楚地，确实地，明显地”，这个单词在考研翻译2003年63题考过，在本句话中，它修饰形容词shaky。Shaky是动词shake(摇动)的形容词，意思是“不稳固的，摇晃的”，在本句话中它修饰“证据”，说明“证据站不住脚”。
