听写训练营Day34

1. Today, we are taking a little detour from the grand styles of public architecture we’ve been studying, to look at residential architectures in the United States, since this is something we can all identify with, I think it will help us see the relationship between the function of a structure and its style or form, this has been an ongoing theme in our discussion, and we will be getting back to it just a moment. 

2.Definitions vary, but I'm taking it to refer to a whole range of behaviours that the victim finds unacceptable, from minor, harmless arguments to, at the opposite extreme, physical violence, much of this is covered by the term bullying, by which I mean one or more people behaving abusively or aggressively against another who is in a weaker position.

3. So we have been fairly thorough in our discussion about coral reefs, which of course are prominent, oceanic features made of hard limestone skeletons produced by tiny coral animals, we’ve gone over where coral reefs are usually formed, along the edges of shallow ocean banks in tropical or subtropical regions, and the fact that they are declining at an alarming rate, but I don’t want to leave you with the impression that all is lost. 

4.Now, we've talked in depth about coral bleaching, or whitening, which as you recall, is a symptom of, well, that the coral is suffering, as you know, coral is very sensitive to water temperature, even though one or two degree Celsius rise in sea surface temperature for a relatively short amount of time can cause bleaching, recently, researchers have used data collected by monitoring surface water temperatures to improve the ability of a reef to recover from bleaching.

5. And there's another technique that's been experimented with to try to help coral reefs recover from bleaching, it's called coral transplantation, this involves moving young coral from a healthy reef onto a degraded reef, you know, in an attempt to regenerate the degraded reef by encouraging young healthy coral to take over, there has been some success with this, but it's still somewhat controversial.
