[1]Global difference in intelligence is a sensitive topic, long filled with a large number of different opinions. But recent data has indeed shown cognitive (认知的) ability to be higher in some countries than in others. What's more, IQ scores have risen as nations develop—a phenomenon known as the "Flynn effect". Many causes have been put forward for both the intelligence difference and the Flynn effect, including education, income, and even non-agricultural labor. Now, a new study from researchers at the University of New Mexico offers another interesting theory: intelligence may be linked to infectious-disease rates.
  [2]The brain, say author Christopher Eppig and his colleagues, is the "most costly organ in the human body". Brainpower consumes almost up to 90 percent of a newborn's energy. It's clear that if something affects energy intake while the brain is growing, the impact could be long and serious. And for vast parts of the globe, the biggest threat to a child's body—and therefore brain—is parasitic (由寄生虫引起的) infection. These illnesses threaten brain development________________. They can directly attack live tissue, which the body must then try every means to replace. They can invade the digestive pipe and block nutritional intake. They can rob the body's cells for their own reproduction. And then there's the energy channeled (输送) to the immune system to fight the infection.
  [3]Using data on national "disease burdens" (life years lost due to infectious diseases) and average intelligence scores, the authors found they are closely associated. The countries with the lowest average IQ scores have the highest disease burdens without exception. On the contrary, nations with low disease burdens top the IQ list.
  [4]If the study holds water, it could be revolutionary for our understanding of the still-confusing variation in national intelligence scores.

完形填空

  A man came home from work late again,tired and irritated(烦躁的),to find his 5?year?old son waiting for him at the door.“Daddy,how much money do you make an hour?”

  “What makes you ask such a thing?” the man said   1  

  “Please tell me.” begged the little boy.

  “If you   2   know, I make $20.00 an hour.”

  “Oh,” the little boy replied, head   3  

  Looking up, he said, “Daddy, may I   4   $10.00,please?”

  The father was angry.“I work long,   5   hours every day and feel tired.March yourself straight to your room and go to bed.Think about why you’re being so   6  .” The little boy quietly went to his room and shut the door.The man sat down, angry with his son.  7   an hour or so, the man had   8   down, and started to think he may have been a little   9   on his son.Maybe there was something he really   10   to buy with that $10.00.The man went to the   11   of the little boy’s room and opened it.

  “I’ve been   12  .Maybe I was too hard on you earlier.It’s been a long day and I threw my   13   out on you.Here’s that $10.00 you asked for.” said the man.The little boy sat   14   up, pleased.“Oh, thank you, daddy” he yelled.Then, he   15   out some more crumpled up(褶皱的)bills from under the pillow.The man,   16   that the boy already had money, started to get angry again.The little boy slowly   17   out his money.“Why did you want more money if you already had some?” the father complained.

  “Because I didn’t have   18  , but now I do,” the little boy replied.

  “Daddy, I have $20.00 now.Can I buy an hour of your time?”

    19   $20.00 worth of time with someone you love…just a short reminder to all of us working so hard for our living.Just spend some quality time with those who really   20   to us.
