1 e7 S9 F! \. J' D0 aI understand your professor has been dicussing several Eastern Woodland (Indian tribes部落) in your study of Native American curltures. As you have probably learn, the Eastern Woodland Indians get their name from the (forest-covered areas) of the Eastern United States where they lived. The earliest Woodland curltures (date) back 9000 years, but the group we`ll focus on dates back only to about 700 A.D. We now call these Native Americans the <Mississippian密西西比的> curlture, because they settled in the Mississippi River valley.% ^, c9 J1 b0 z1 d2 n) J

(The experiment is) based on the well-established observation that babies <stare> a longer if they don`t see what they espect to see. First, we`re going to let two dolls moves slowly in front of the babies. The babies will see the two dolls disappear behind a screen. Your job is to record, in seconds, how long the babies stare at the dolls when the screen is removed.4 P$ s* A! X8 w4 a( l& _* Y
5 B# W5 R! P( OIn the next stage, two dolls will again moving in front of the babies and disappear. But then a third doll will follow. When the screen is removed, the babies will only see two dolls. If we`re right, the babies will now stare longer because they espect three dolls but they only see two.

It seems remakeable to think that such young children can count. My own research has <convinced说服,使相信> me that they have this ability from birth. But whether they do or not, perhaps we should (raise) another question---should we take advantage of利用 this ability by teaching children <mathematics> at such a young age? They have great (untapped 未使用的) <potential潜力> but (is it) good for parents to pressure young children?( W+ c7 K3 T( R* B+ q3 Z: Y
