关于Dec.3的听力
题目是：Even Low Lead Levels Lower IQ
但是文中有一句是“Turned out that those in the 5-10 group had IQ scores about five points lower than those with the lowest lead levels. ”意思不是5-10那组的IQ比含铅水平少的人低5个点吗？那不是还是含铅高的人的IQ地吗？这岂不是与题目相悖吗？
注：鄙人天资愚笨，加上英语水平有限，请勿嘲笑~~~并且谢谢各位能帮助我~~~~~~~~

题目的意思是"即使是比较低的铅含量也会导致较低的IQ",因为文章中说了10以下以前都是认为是可以接受的含量,即5-10也算比较低的.而不是说铅含量越低IQ越低.
别把自己说的那样.要有信心丫.大家都是一步步过来的嘛.^^:)

Pygmies Trade Height For Fecundity

It’s that time of the year when many of us ponder deep questions, like: What have I done with my life? Where am I going? And, Why are pygmies so small?  Well, you’re on your own with the first two questions. But researchers at the University of Cambridge may be able to help with the third.  They published their conclusions in the current issue of the Proceedings of the National Academy of Sciences.

For years, scientists have theorized about the diminutive stature of pygmies—populations where the men never top five feet. The current theories hold that pygmies have evolved to be short in response to a scarcity of nutrients. Or maybe, get this, because it’s easier to make your way through dense forests if you’re not so tall.  But somehow those theories never quite fit. The Masai in Kenya also face famine, and they’re among the tallest people on the planet. And as for ducking under branches—not all pygmies live in the woods.  What the Cambridge researchers find is that pygmies are pygmies because they live fast and die young.  And adolescent years that are usually spent growing taller are instead used to have babies, usually by the age of 15.  So the research confirms what we always knew: pygmies lead short lives.
