[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.

小题1:Why do IQ scores vary by nation? / Why do IQ scores vary from nation to nation?/Different IQ between nations may result from infectious diseases.
小题2:highest disease burdens
小题3:in several ways
小题4:Education, income and non-agricultural labor.
小题5:National disease burdens and average intelligence scores
解析
试题分析:
小题1:文章主要讲述的正是在不同的国家里人们的智商是不一样的。
小题2:根据文章倒数第二段The countries with the lowest average IQ scores have the highest disease burdens without exception.那些疾病流传很广的国家的人们往往智商都不算高。
小题3:根据下文可知是疾病在不同的方面威胁着人们智力的发展。
小题4:根据文章第一段4,5行Many causes have been put forward for both the intelligence difference and the Flynn effect, including education, income, and even non-agricultural labor.
小题5:They指代的正是上一句Using data on national "disease burdens" (life years lost due to infectious diseases) and average intelligence scores中提及的national disease burdens and average intelligence scores
点评:阅读表达的题目要根据文章的内容进行回答,有的是细节题,到相关的段落寻找关键句,得出答案,还有推理题,要根据相关的句子找出作者想要表达的意思,考查学生的理解力。

举一反三
Why Is Exercise Cool?
Exercise strengthens Muscles
Did you ever do a push-up or swing across the monkey bars at the playground? 小题1: By using your muscles to do powerful things, you can make them stronger. For older teens and adults, this kind of workout can make muscles bigger, too.
小题2:
Can you touch your toes easily without yelling ouch? Most kids are pretty flexible, which means that they can bend and stretch their bodies without much trouble. Being flexible is having “full range of motion” , which means you can move your arms and legs freely without feeling tightness or pain.
Exercise Keeps the Balance
小题3: Your body needs a certain amount of calories every day just to function, breathe, walk around, and do all the basic stuff. 小题4: If you’re not very active, your body won’t need as many calories. Whatever your calorie need is, if you eat enough to meet that need, your body weight will stay about the same. If you eat more calories than your body needs, it may be stored as extra fat.
Exercise Makes You Feel Good
It feels good to have a strong, flexible body that can do all the activities you enjoy---like running, jumping, and playing with your friends. It’s also fun to be good at something, like scoring a basket, hitting a home run, or perfecting a dive.
But you may not know that exercising can actually put you in a better mood.小题5: It’s just another reason why exercise is cool!
A.So you want to do some aerobic(有氧的) exercise right now? |
B.Food gives your body fuel in the form of calories, which are a kind of energy. |
C.When you exercise, your brain releases a chemical, which may make you feel happier. |
D.Those are exercises that can build strength. |
F. Exercise Makes Your Heart Happy
G. But if you’re active, your body needs an extra measure of calories or energy.
