【解析】本句是一个倒装句，可还原为：if they had known what was coming next, they might have had second thought。根据had known提示，可知是与过去事实相反，因此虚拟语气主句中应该用would/might +have done，由此可见答案D符合语境。
【难度】较难
20. — I'm going to San Francisco for a couple of days.
— ___ . I wish I could get away for a while. A. It doesn't matter B. Forget it C. I really envy you D. I can't agree more 20.【考点】交际用语—征求意见或看法
【答案】C
【解析】根据句意：---我要去圣弗朗西斯科几天。---真羡慕你（I really envy you）。我多么希望我也可以离开一会儿呀。与I wish相呼应，故答案C符合语境。It doesn’t matter ，没有关系；forget it别提了；I cant agree more完全赞同，均不符合语境，故排除。
【难度】中等

Easter(复活节 ) is still a great day for worship, randy in baskets and running around the yard finding eggs, but every year it gets quite a bit worse for bunnies.
And no, not because the kids like to pull their ears. The culprit is climate change, and some researchers found that rising temperatures arc having harmful effects on at least five species of rabbit in the US.
Take the Lower Keys March rabbit, for instance. An endangered species that lives in the Lower Florida Keys, this species of cottontail is a great swimmer — it lives on the islands! — but it is already severely affected by development and now by rising levels. According to the Center for Biological Diversity, an ocean level rise of only 0. 6 meters will send these guys jumping to higher ground and a 0.9-meter rise would wipe out their habitat (栖息地) completely.
The snowshoe hare, on the other hand, has a color issue. Most of these rabbits change their fur color from white in the wintertime to brown in the summer, each designed to give them better cover from predators（捕食者）. As the number of days with snow decreases all across the country, however, more and more bunnies arc being left in white fur during brown dirt days of both fall and spring, making them an easier mark for predators. Researchers know that the color change is controlled by the number of hours of sunlight, but whether the rabbit will be able to
