20190607长难句 / 开普饭

【昨日回顾】

One basic weakness in a conservation system based wholly on economic motives is that most members of the land community have no economic value.

在一个完全以经济目标为基础的(生态)保护系统中，一个根本弱点在于陆地群落的大多数成员没有经济价值。

【今日长难句】

Yet these creatures are members of the biotic community and, if its stability depends on its integrity, 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.

【首句结构分析】

1. 本句是由and连接的并列句，前半句为主系表结构，即：these creatures /are/ members of the biotic community.

2. and之后的后半句由if引导条件状语从句和主句构成。

3. 今日长难句难点在于词汇。

【二句结构分析】

“and”连接“when” 引导时间状语从句与“if”引导的条件状语从句，句子主干为主谓宾结构，即：we/invented/ excuses…; “to give it economic importance” 为目的状语。

【词的处理】

noneconomic /'nɔn,i:kə'nɔmik/ adj. 无实用价值的；无经济价值的

category /ˈkætəɡəri/ n. (人或事物的)类别,种类

【参考译文】

Yet these creatures are members of the biotic community and, if its stability depends on its integrity, 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.

但是这些生物是生物群落的成员，并且如果该群落的稳定性依赖其完整性，那么这些生物有权/应该继续生存。当这些无经济价值的物种之一受到威胁时，并且如果我们正好喜欢它，我们就会编造理由来赋予其经济价值。

【明日长难句】

At the beginning of century, songbirds were supposed to be disappearing. Scientists jumped to the rescue with some distinctly shaky evidence to the effect that insects would eat us up if birds failed to control them.
