【简答题】
阅读理解 Many parents don't love to read to their children.But there are so many professionals and PhDs doing the opposite thing.And they really promote reading to children, which is so good for children.I have found that this is true with my own children. I am not sure if it is the book or the fact that you are spending quality time with them, undivided time that they will remember for their entire life.Reading to children is one of the most bonding experiences you can have. Children enjoy sitting on your lap while your voice flows over them.As the reader it is fun to watch their littl e faces as they are moved with the flow of the story.They are laughing one moment and on the next page the story has moved them to tears.As the storyteller, I am just as moved as they are;I am caught up in the story as our emotions flow up and down.You can easily lose a whole afternoon in reading. This is an experience that children then try to pass on to younger children, reading books to them.My daughter was so into reading that if she couldn't line up some neighbors'children she could be reading her books to, she would line up her stuffed animals and read to them.Well, she also tried to teach her neighbors and teddy bears math, and 'ocean science 'as she called it.She would read anything she could to them. And to my astonishment the neighbors'parents told me they really appreciated the fact that their children were doing so much better in school. 1.
