题干考查的是，将文中5个划线语句，翻译成汉语。现就这5个句子，提出我们的参考答案如下：

1. 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。

句子结构如下：主干为Scientist jump to the rescue.，with some distinctly shaky evidence构成jump的伴随状语，to the effect that 是evidence的同位语从句。对于这个句子的翻译，真可谓“五花八门”，其中大多都没有正确理解evidence、effect和后面小句间的关系，就是间或有理解的，汉语的表达也不是很恰当。针对这种情况，我们尝试重新翻译一下。

参考答案：科学家匆忙赶来救急，但所提出的证据有点明显站不住脚，其大意如下：如若没有鸟类制衡昆虫，昆虫就会吞噬我们。

2. But we have at least drawn nearer the point of admitting that birds should continue survival as a matter of intrinsic right, regardless of the presence or absence of economic advantage to us。
