转基因食品开始盛行

1.When it comes to genetically modified crops, Europe is looking increasingly isolated.

【参考翻译】谈到转基因农作物，欧洲似乎越来越被孤立了。

【结构分析】When it comes to 表示讲到什么，说到哪个问题。

You may not be weak, but when it comes to money, you get wimpy.
你也许不是一个无能的人,但是说到挣钱,你可能并不在行。

2.Yes, yeah and we've got a number of candidate genes where we think if we could either over express these or knock them out that we'll stop this happening.

【参考翻译】是的，我们还有许多候选基因，我们认为如果可以让这些基因特性显现出来，我们就能阻止这种情况发生。

【结构分析】where we think是定语从句，修饰candidate genes。 if we could either over express these or knock them out是宾语从句，think的内容。eigher……or表示选择。stop sth happening其实是stop sth from happening的简写，from可以省略。

3.Yeah that is often a reaction, this doesn't look like GM wheat because it looks perfectly normal but that very much depends on the genes that we have transformed with, so a gene that you might hope changes the pre-harvest sprouting effect isn't likely to be something you can see.

【参考翻译】是啊，这是人们通常的反应，这看起来不像是转基因小麦，因为它外型和普通小麦完全一样，但外型很大程度上取决于我们改变的基因，改变收获期前发芽问题的基因在小麦外型上不大看得出来。

【结构分析】(1)that we have transformed with是定语从句，修饰the genes。
(2)so a gene that表结果。so +形容/副词+that，so+形容词/副词+a+名词+that，都是结果状语从句。
