[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 (認(rèn)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 (由寄生蟲(chóng)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 (輸送) 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.

Years ago, I lived in a building in a large city. The building next door was only a few feet away from mine. There was a woman who lived there, whom I had never met, yet I could see her seated by her window each afternoon, sewing or reading.
After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself, "I wonder why that woman doesn't wash her window. It really looks terrible."
One bright morning I decided to clean my flat, including washing the window on the inside.
Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was clearly visible. Her window was clean!
Then it dawned on me. I had been criticizing (批評(píng)) her dirty window, but all the time I was watching hers through my own dirty window.
That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own shortcomings?
Since then, whenever I wanted to judge (評(píng)判) someone, I asked myself first, "Am I looking at him through my own dirty window?"
Then I try to clean the window of my own world so that I may see the world about me more clearly.

A traveller was staying in an Egyptian village. One day, she held up her camera to take pictures of the children. Suddenly the young ones began to shout at her. The traveller's face turned red and she apologized to the head for what she was doing, and told him she had forgotten that people in some places believed a person would lose his soul(靈魂) if his picture was taken.

Normal bicycle safety guides usually tell you to wear you helmet(頭盔) and to obey the law in order to avoid being hit on a bike. Is this advice really helpful?

Consider this for a moment: Wearing a helmet will absolutely do nothing to prevent you from getting hit by a car. Surely, a helmet might help you if you get hit, but you No.1 goal should be to avoid getting hit. Plenty of cyclists were killed by cars__________. However, if they had ridden without helmets, yet followed the guidelines listed below, they might still be alive today. So they saying that wearing a helmet is the first and last word in bike safety is, to some degree(在一定程度上), wrong.

The most common bike safety advice is “follow the law”. Ridiculously, most people are already aware that it’s stupid to race through a red light at a crossroads. As a result, it’s clear that the “follow the law” advice isn’t that helpful, either. In addition, following the law is not enough to keep you safe. Here’s an example: The law tells you to ride on the right, but if you ride too far to the right, someone started a parked car could open their door right in front of you and motorists pulling out of driveways and parking lots will be less visible. In that case you were following the law, but could still have been hit.

Then what should we remember in order to keep safe when riding a bike? I will tell you about it in the following paragraph.

1.What does the author say about wearing a helmet in the second paragraph?(within 8 words)

2.Which sentence in the passage is the closest in meaning to the following one?

However, nearly everyone knows that riding through hared traffic light is dangerous.

3.Please fill in the blank in the second paragraph with proper words or phrases to complete the sentence.(within 5 words)

4. List the two regular bike safety guides.(within 8words)

5.Translate the underlined sentence in the third paragraph into Chinese.
