2, find out the conditions, every sentence in the topic is not nonsense, there are conditions, we must learn to find out, combined with conditions, so as to solve it correctly.

3. Write an error correction book to understand why you made a mistake, whether you were careless and didn't find the known conditions, or whether you didn't know or didn't know the knowledge points embodied in this question at all. You should understand the mistakes and know how the answers are made. What's he thinking?
