题型:探究题

有两只相同的烧杯,分别盛有体积相同的水和酒精,但没有标签,小李采用闻气味的方法判断出无气味的是水。小唐则采用压强计进行探究:

(1)若压强计的气密性很差,用手指不论轻压还是重压橡皮膜时,发现U形管两边液柱的高度差变化 _________(选填“大”或“小”)。小唐把调节好的压强计放在空气中时,U形管两边的液面应该_______。

(2)小唐把金属盒分别浸入到两种液体中,发现图 (甲)中U形管两边的液柱高度差较小,认为图(甲)烧杯中盛的是酒精。他的结论是不可靠的,因为没有控制金属盒在液体中的_________ 相同。

(3)小唐发现在同种液体中,金属盒离液面的距离越深,U形管两边液柱的高度差就越________,表示液体的压强越__________。

(4)小唐还发现在同种液体中,金属盒距液面的距离相同时,只改变金属盒的方向,U形管两边液柱的高度差_________(选填“不变”或“变化”)。表明在相同条件下,液体内部向各个方向的压强_______。

    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.
