What's the difference between "for -ing" and "to..."? I have one question. English grammer in Use says, '1.In these examples "to ..." tells us the purpose of something: why somebody does something, has something, need something etc., or why something exists' and '2.You can use "for -ing" or "to ..." to talk about general purpose of something'. But it also says '3.we do not use "for -ing" to say why somebody does something'. It seems a little conflict between rule1,2 and rule3. Or rule 3 just represents to us that 'why somebody does something' isn't one of 'general purpose of something'?

what does "would hate" mean here? The following sentence is from a book I read. Poor David! I would hate to heve been in his position. What does "would hate" mean here?

English name My colleague wants to make an English name. The pronunciation of his Chinese name is like "ren da". Is there any suitable English name? The pronunciation is the closer the better. He also wants the name has a good meaning in English.

Is this right? If I want to tell somebody what Paul said, I can use 'Paul said that something...'. But if something is written on a book or newspaper, can I use 'The book/newspaper said that something...'?

What is the difference between "could" and "might", when we are talking about something is not real? In the grammar book, it says "We also use could for actions that are not realistic" and "We use might when the situation is not real". So, can I use either "could" and "might" when I'm talking about something is not real. For example, does the following 2 sentences have the same meaning? If not, what is the difference? If they paid me better, I might work harder. If they paid me better, I could work harder.

My reflection of reading Angel’s blood chapter1~2 I love to read novels and am reading Guild Hunter recently. My English is not good, so I just read 2 chapters in 2 days. I still think I should take notes though I just read such few pages. On one hand, I'm afraid that I might forget the previous story after I have read more chapters. On the other hand, I can practice my English writing skill. Vampires in this book are hardly afraid of sunlight and the same as those in the Twilight. But there are much more differences between these 2 kinds of creatures. To my surprise, vampires are produced by angels. They act like zombies within some months after they have been made and it seems that their moving speed are not as fast as those in the Twilight, so they can be caught by hunters easily. Elena--the main character--is a vampire hunter, catches the escaped vampires and returns to the angels. She is meeting with Raphael for a new assignment on the end of chapter2. PS: I'd appreciate it very much if you'd correct any errors I've made.

what does the "snap" mean here? The following sentences come from Angels' Blood chapter 2. "Then drink." It was an instruction so absolute, she knew he expected instant obedience. Something snapped inside her. "Or else?" What does the "snap" mean here?

Can I write "Welcome to correct the error"? If I post a writing and hope someone can help me to correct the error in the article. Can I write "PS:Welcome to correct the error." on the end of the article? Or there are better ways to write it?

The embarrassing things I did in my early years I loved to read story books when I was a child. My mother borrowed one for me and my brother from the library of her school every now and then in my early childhood. I won’t forget Chinese fairy tale-- picture story books about Chinese ancient stories, it has 12 volumes as a total-- that I read a long time ago. I still remember some embarrassing things I had done for reading these books before. One afternoon my mother asked me to go to bed--my family always to take naps in the weekend afternoon. I promised and lay on the bed actually, but hid the book under my pillow. I took out the book to read secretly after she closed my bedroom door. However, my mother is very smart. After about 5 minutes later, she opened my bedroom door suddenly and caught me. Then I can just hand over the book and go to bed obediently. The next weekend afternoon my mother asked me to go to bed again. I also get up and read the book after she had closed my bedroom door, but I paid attention to any sound outside my door this time. When I heard the sound of footsteps toward my room, I hid the book and lay on the bed to pretend that I had been fallen asleep. After I had finished everything, the door opened quietly and someone walked in slowly—I knew that is my mother. After she had stood in front of my bed for several seconds, she said “chilun, get up and give me the book.” I knew that she had seen through me, so I could only give her my book. A few days later, I asked her how she knew that I was pretending. She said “Your eyes closed, but your eye-lid blinked.” After I went to junior high school, I had too much homework and didn’t have time to read story books. Although I have been graduated from university for many years now, I still remember these things and the stories I had read before.
