Night after night，she came to tuck me in，even long after my childhood years．Following her longstanding custom，she'd lean down and push my long．hair out of the way，then kiss my fore—head．

I don't remember when it first started annoying me—her hands pushing my hair that way． But it did annoy me，for they felt work—worn and mush against my young skin．Finally，one night，I shouted out at her，"Don't do that any more--your hands are too rough!" She didn't say anything in reply．But never again did my mother close out my day with that familiar expression of her love．

Time after time，with the passing years，my thoughts returned to that night．By then I missed my mother's hands．missed her goodnight kiss on my forehead．Sometimes the incident seemed very close，sometimes far away．But always it lurked，in the back of my mind．

Well，the years have passed，and I'm not a little girl anymore．Mom is in her mid—seventies．and those hands I once thought to be so rough are still doing things for me and my family．She's been our doctor，reaching into a medicine cabinet(医药箱)for the remedy(药物)to calm a young girl's stomach or soothe(安慰)the boy's scraped knee．She cooks the best fried chicken in the world…gets stains out of blue cans, like I never could…

Now, my own children are grown and gone．Mom no longer has Dad，and on special occasions．I find myself drawn next door to spend the night with her．So it was late on Thanksgiving Eve, as I slept in the bedroom of my youth, a familiar hand hesitantly run across, my face to brush the hair from my forehead．Then a kiss，ever so gently，touched my brow(额头)．

In my memory，for the thousandth time，I recalled the night my young voice complained，"Don't do that any more--your hands are too rough!" Catching Mom's hand in hand，I blurted (冲口说出)out how sorry I was for that night．I thought she'd remember ，as I did．But Mom didn't know what I Was talking about．She had forgotten--and forgiven—long ago．

That night, I fell asleep with a new appreciation for my gentle mother and her carrying hands. And the guilt that I had carried around for so long was nowhere to be found．

About one million years ago,the Ice Age began.The Ice Age was a long period of time in which four great glaciers(冰川) pushed southward to cover almost all the upper half of North America,and then melted away.Each glacier was a thick sheet of ice and snow that spread out from a center near what is now Hudson Bay in Canada.The winters were long,and the cool summers were too short to melt much of the ice and snow.The ever?growing sheet built up to a thickness of two miles at its center.

As all glaciers do,these great glaciers slid(滑动). They pushed down giant trees in their paths and scraped(刮削)the earth bare(光秃秃)of soil.Many animals moved farther south to escape.Others stayed and were destroyed.

When winters of little snow came,the summer suns into the edges to the ice sheets.As the glaciers melted,rocks,soil and other things that had mixed with the ice and snow were left.New hills,lakes and rivers were formed.

The last of the great glaciers began its melting about 11 000 years ago.Itsmelting formed the Great Lakes.These lakes are today little changed from their early sizes the glaciers.This is the Mississippi Missouri Ohio system.These rivers were miles wide at first.Through the years they settle into their present channels.

What do you do if you are hit in the mouth and one of your teeth is knocked out? A dentist(牙医)may be able to put the tooth back in for you, but you have to get to the dentist first．In the meantime, you have to store the tooth so that it will stay healthy．

The simplest thing to do is put the tooth back into your mouth, or you could put it in milk．Frank Courts, a dentist at the University of Florida, worked with other researchers to find the safest way of keeping knocked-out teeth．He tried putting teeth into milk, into water, and into cell-culture medium(细胞培养液)．He also tried, just drying the teeth in the open air．He used teeth that had to be removed from people’s mouths for various reasons．The teeth were put into one of the solutions(溶液)or stored in the air for one hour．Then cells from the root of the teeth were scraped-off the teeth．Dr．Courts and the others then studied how healthy these cells were．

The cell-culture medium worked best to keep a knocked-out tooth healthy outside the mouth．However, few people keep cell-culture medium handy at home or in school．

The next best thing was milk．But Dr．Courts said that the best thing of all was to wash the tooth and put it right back into its socket(牙槽)in the mouth．For some people, though, this is just too painful or upsetting．So milk will do, until you get your tooth (and your mouth)to a dentist．
