【答案解析】woman： Do you know the name of the trees besides the sea over there? man： Yeah, it is mangrove, right? woman： Exactly. I have thought that you would have no idea of what it is since you come from an inland city. man： Well, I didn't know it until one day when I read an article about it with its picture in National Geographic. The mangrove forests act as “coast guard” to protect the seashore from flood. And I have also done some study on the risks that their seedlings face. woman： Seedlings? Well, what risks? man： According to some statistics, every year, lots of the mangrove seedlings are destroyed by storms. woman： It isn't surprising. You know storms can destroy everything. man： Yeah. And in some small islands, there is an increasingly number of rabbits day by day, which also makes it very necessary to take some measures to slow down the reproduction rate because the rabbits always eat the seedlings. woman： Wow. Little things can make a big difference. man： Yeah, so every small aspect should be taken into consideration to make sure that the mangrove seedlings can grow up smoothly.
