[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.

[1]One Friday night in May 2010, Oliver and Ione Kleven heard angry shouts coming from their front lawn(草坪). Ione, 65, stepped onto the porch（门廊） and saw two men in dark clothes struggling with something on the ground—right where she and her grandson had planted a flower bed the weekend before.
[2] “Go fight somewhere else!” she shouted, worried her plants would get damaged. At the sound of her voice, the face of a boy appeared from beneath the two men. He looked 14. “They’re trying to kill me!” the boy screamed. Ione ran toward them and, without hesitation, caught the boy’s arm, pulling him out.
[3] “Leave him alone!” she shouted. When the men stood up, Ione saw what looked like a sharp object in one man’s hand. When she turned back toward the boy, he was moaning（呻吟） in pain and holding his stomach. The attackers began to move in on the boy again when Ione’s husband shouted: “Get lost!” The two men walked quickly and quietly across the street and drove off in a dark car.
[4]“I have to get to the hospital!” the boy cried. He lifted his shirt, and Ione could see a bloody wound on his stomach. Oliver hugged the trembling(发抖的) boy while Ione caught her cell phone and car keys inside the house. She handed the phone to Oliver. “Call 911,” she told him. “I’m going after them.” Ione took off but was unable to find the car.
[5]The Klevens then learned what had happened . Earlier that night, as the boy waited for his parents to pick him up from the high school across the street from the Klevens’ house, two men approached and demanded his wallet. When he refused, one of the men hit him in the face. The boy ran across the street. The men caught up with him, and one hurt him in the back and stomach with a sharp knife. That’s when Ione stepped in.
56. When was Ione born? (within 2 words)
57. Why did Ione shout at the two struggling men? (within 8 words)
58. Whom does the underlined word “him” (in Para.3) probably refer to? (within 3 words)
59. Why did Ione hand the phone to Oliver? (within 8 words.)
60. What was the boy doing when the two men approached him? (within 10 words.)
