[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.

Riding was the favourite activity of Thomas Jefferson, who was the third President of the United States. He usually rode good horses.
One day, he was riding outside Washington, when a jockey (赛马师) came near. He did not know the President, but his professional eye was attracted by Mr. Jefferson’s horse. He stopped and said that he wanted to buy the horse, but Mr. Jefferson politely refused his offer.
The jockey offered more money for the horse, because the closer he looked at the horse, the more he liked it. All of his offers were refused, which made him angry. He then became rude, but his rudeness left as little an impression as his money, for Jefferson had a very good temper. At last, he hit Mr. Jefferson’s horse with his whip, getting it to run suddenly. This would have thrown a less skillful rider to the ground, but Jefferson stayed on his seat, and controlled his horse well.
The jockey then gave up. He rode with Mr. Jefferson side by side and began to talk with him about politics. Jefferson joined in the conversation. When they got into the city and came close to the gate of the presidential mansion (总统府), Mr. Jefferson stopped, and politely invited the man to enter.
The jockey was surprised and asked, “Why? Do you live here?”
“Yes” was the simple reply.
“Why, stranger, what’s your name?”
“My name is Thomas Jefferson.”
Embarrassed, the man quickly left, while the President looked at him with a smile and then rode through the gate.

In America, when people say “man’s best friend”, they don’t mean another person. Instead, they are talking about a lovely animal：A dog! These words show the friendship between people and animals. Dogs and other pets can give happiness to people’s lives. Some people regard their pets as their children. A few even leave all their money to their pets when they die!
Animals can help people, too. Dogs can be taught to become the “eyes” for a blind person or “ears” for a deaf people. Scientists have found that pets help people live longer! They make people happier, too. Because of that, animals are brought into hospitals for “visit”.
Americans hold “Be---Kind-to-Animals Week” in the first week of May. Pets shows are held during the week. Even if you don’t live in America, you, too, can do this. How? First, think about how animals make your life richer. If you have a pet, take more time this week to play with it. Remember to give it delicious food. Also, be sure to keep your pet from those unwanted babies.
f you don’t have a pet, be kind to animals around you. For example, if you see a street dog, don’t kick it or throw things at it. Instead, just leave it alone, or better yet, make friends with it. If others around you do bad things to an animal, try to stop them. As people, we must protect animals who can’t speak for themselves.

The 47-year-old singer talks about the new album Symphony（交响乐） that came out of a “very dark time”, including her decision to give up trying to have children. “People have suggested I could adopt,” Brightman says. “But work is central to my life now. And so I am going to put it to one side. After a while not having children becomes the norm and perhaps that might sound alarming, to parents especially, but I have never known anything different. I’m not hurt by not having children. My life and career are incredibly rich.”
Talking about growing up in a large family in Berkhamsted (father a property developer who later committed suicide), she says: “I was gifted as a child, and very musical. I seemed to be good at anything to do with the arts. At 5，I understood the music I was dancing to and had an eye for costume.” She first appeared in a West End musical at 11 and hated boarding school.
Brightman led the saucy dance troupe（辣妹三人舞） Hot Gossip and had her first hit with I Lost My Heart to a Starship Trooper in 1978. At 18 she married a music manager called Andrew Graham Stewart. “I was probably in love but I can’t remember. Girls change such a lot between 18 and 22. It didn’t really work out.” In 1981 she was spotted by Lloyd Webber. She became his leading lady in Song and Dance, Requiem and Phantom of the Opera. They married in 1984.
Brightman says she felt hostility(敌意) “from the beginning. I haven’t tried to understand it. I’ve done very well everywhere else, especially the US, where I now live, I just accept it for what it is. The more you are away from Britain, the more you appreciate it. But I don’t miss it, although I miss my family. Our profession can be uncomfortable but I enjoy what I do. I get on with it.”
