我一直深信我父母的婚姻很美满，但是当我——四个孩子中最小的一个——快满十六岁的时候，我这种想法受到了严峻的考验。

I always believed that my parents had a good marriage, but just before I, the youngest of four children, turned sixteen, my belief was sorely tested.

这样的想法很美好，但我很少有这种感觉。

It would be nice to think so, but I don't usually get that feeling.

这是一个很美好的想法，但是Lamarck错了，需要的特性并不能通过这种方式传输。

It was a nice idea, but Lamarck was wrong. Acquired characteristics cannot be transmitted in this way.

It doesn't work so easily to share with those people along the lines that these communities--I think these communes tend to emphasize a social compact, a feeling for each other, a caring for each other, which is a lovely thought but it doesn't achieve risk management on a big scale.

但要实现跟满足这些条件的人分摊风险,绝非易事,这些共同体。。。我指这些公社,倾向于强调一种社会凝聚力，一种人与人的深情和关怀，这个想法听上去很美,但无法实现大规模有成效的风险管理。
