　　答案：C

　　解析： A lot of different types of trees in an area might mean more pedodiversity.

　　也就是在森林里有more pedodiversity。

　　What does the professor suggest are the three main causes of pedodiversity in the old-growth hardwood forests she discusses?Click on 3 answers.

　　答案：D

　　解析：For instance, without a tree to absorb radiation from the sun, tool for shade, the full intensity of that radiation reaches the ground. The soil where the tree used to be heats up. And without a tree to soak up moisture from the ground, the soil remains wetter than in the surrounding forest. With a high temperature and more moist conditions, the process of organic matter decompositions beats up.

　　这些话是在解释gap的作用。

　　解析：I want you to read it because it makes the point I only touched on..........As the article explains, forest dynamics affects pedodiversity.

　　也就是关于forest dynamics与 pedodiversity的关系。

　　D. To exemplify that the reverberation time of a room is related to its size

　　答案：AD

　　解析：A single instrument, something like a piano recital, a room with a short reverberation time is better.So for a solo piano, a small room works well.

　　说明房间的size与reverberation time有关系，而better这种比较则说明不同乐器需要不同的room size。
