[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.

Wednesday，October fifteenth，is the first Global Hand Washing Day. Activities are planned in more than twenty countries to get millions of people in the developing world to wash their hands with soap（肥皂）. Experts say people around the world wash their hands but very few use soap at so-called critical(至关重要的) moments. These include after using the toilet，after cleaning a baby and before touching food.

Global Hand Washing Day is the idea of the Public-Private Partnership for Hand Washing with Soap. Partners include the United Nations Children’s Fund, and soap makers Unilever and Procter and Gamble. The goal，they say，is to create a culture of hand washing with soap.

The organizers say all soaps are equally effective at removing disease-causing germs(病菌). They say the correct way to wash hands is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas，including under the fingernails. Then，rinse（用清水冲洗） well under running water. Finally，dry your hands with a clean cloth.

The Partnership says soap is important because it increases the time that people spend washing. Soap also helps to break up the grease（油脂）and dirt that holds most of the germs. And it usually leaves a pleasant smell，which increases the possibility that people will wash again. It also says washing with soap before eating and after using the toilet could save more lives than any vaccine（疫苗）or medicine. When people get germs on their hands, they can infect themselves by touching their eyes, nose or mouth. Then they can infect others.

1.Global Handwashing Day is set to ______________.

A. create a culture of hand washing with soap      B. force people to wash their hands

   C. teach people how to wash their hands         D. protect people from being hurt by germs

2. Which one shows the advantages of washing hands with soap?

① increasing the washing time                 ② preventing any infection

③ removing disease-causing germs               ④ helping people to wash more

⑤ keeping vaccine away

A. ①②③               B. ①②④           C. ②③⑤           D.①③④

3.The main idea of this passage is to ______________.

   A. introduce Global Handwashing Day              B. remind people to care about their health

   C. criticize people who don't use soap to wash hands     D. help soap makers to sell more soap
