做这种题目有个技巧，就是把倒装的定语从句还原成原来的语序
1. of which. I heard____the book; it was written twenty years ago. 空里应该填of，然后the book 又是物，所以应该用which来指代，连起来就是of which。
2. to whom. The man spoke_____the people, but they weren't listening. 空里面应该填to (speak to somebody)，然后people是人，而且是动作的对象，所以用whom。
依此类推：
3. at which. I fell asleep at the film, which was very boring.
4. with which. She wrote that book with the pen，which can now be seen in a museum.
5. in which. Scientists are interested in the little creature, which is known as ET.
6. by which. He was shot by the gun, which was never found.
这样解释可以吗？
be happy不等于happiness
happiness 是名词，意为 幸福
be happy是要开心的意思happy 是形容词，be是补充句式用的
