Boys at the top of the pecking order(長幼次序) either by birth or because their older brothers died score higher on IQ tests than their younger brothers.

Norwegian researchers now report that it’s a matter of what they call social rank in the family that gives the first born the highest scores or, if the first born had died young, the next oldest.

Kristensen and Bjerkedal studied the IQ test results of 241,310 Norwegian men drafted(征兵) into the armed forces between 1967 and 1976. All were aged 18 or 19 at the time.

The average IQ of first-born men was 103.2, they found second-born men averaged 101.2, but second-born men whose older brother died young scored 102.9. And for third-borns, the average was 100.0. But if both older brothers died young，the third-born score rose to 102.6.

The findings provide “evidence that the relation between birth order and IQ score is dependent on the social rank in the family and not birth order as such.” they concluded.

It’s an issue that has been hotly discussed since at least 1874,when Sir Francis Galton reported that men in noticeable positions tended to be firstborns more often than would have been statistically (統(tǒng)計(jì)) expected.

Since then, several studies have reported higher intelligence scores for firstborns, while other analyses have questioned those findings and the methods of those reports.

“These two researchers prove that how study participants(參與者) were raised, not how they were born, is what actually influences their IQs,” said Sulloway, an American professor, who was not part of the research team.

“The elder child pulls ahead,” he said, “perhaps as a result of learning gained through the process of tutoring younger brothers and sisters”.

“The older child benefits by having to organize and express its thoughts to tutor youngsters”, he said, “while the later born children may have no one to tutor.”

1.According to Norwegain researchers’ finding, which of the following is linked to boys’ IQ?

A. Birth order B. Position in the family

C. Parents’ social rank D. Educational experience

2.What does the sentence “It’s an issue that has been hotly discussed” underlined in Paragraph 6 mean?

A. Many people take interest in IQ study.

B. IQ study has gone further and further.

C. Many people do research on boys’ IQ.

D. Opinions are divided on the conclusion.

3.According to Kristensen and Bjerkedal’s test results, parents can make youngsters smarter by ________.

A. treating them as the oldest child

B. teaching them as the oldest child

C. talking to them as much as possible

D. encouraging them to express thoughts

Bottled water has become the choice for people who are healthy and thirsty. Bottled water is all over the world. But some say the planet’s health, and people’s health may be suffering from it.

The idea that bottled water is safer for humans may not be true. The Natural Resources Defense Council of America said, “There is no promise that because water comes out of a bottle, it is cleaner or safer than water from the tap.” Another New York City-based action group added that some bottled water is “really just tap water in a bottle—sometimes more clean, sometimes not.”

It is not proven that bottled water is better than tap water. Nick Reeves from the Chartered Institution of Water and Environmental Management said, “The high mineral content (含量) of some bottled water makes them not good for feeding babies and young children.” Also, most bottled water doesn’t have fluoride (氟化物), which can make teeth stronger. Kids are drinking more bottled water and less fluoridated tap water, and some say that’s behind the recent rise in bad teeth.

Storing is another problem. Placed near heat, the plastic bottles can produce bad chemicals (化學(xué)物質(zhì)) into the water.

According to the Environmental Protection Agency, some 2.7 million tons of plastic are used worldwide to bottle water each year. The plastic can take between 400 and 1,000 years to break down.

In terms of energy use, plastic bottles are also not cheap. One report said that if water and soft drink bottlers had used 10 percent recycled materials in their plastic bottles, they would have saved about 72 million gallons of gas.

So, if you are worried about the effect of bottled water on the Earth, you can take the following steps.

● Drink from your tap. Unless your government warns against this, it should be fine.

● Get a container (容器). Carry your tap water in a steel or a lined drinking container, and clean it between uses.

● Keep it cool. Don’t drink from a bottle that has been sitting in the sun, don’t store it near chemicals, and don’t reuse plastic bottles.

● Choose glass containers over plastic if possible. When finished, recycle!

1.What is the main idea of the article?

A. Drinking tap water is the only choice for people.

B. Glass containers are better than plastic bottles.

C. Plastic bottles are harmful to the environment.

D. Bottled water may not be as good as we think.

2.What can we learn about plastic bottles from the article?

A. They break down in less than 300 years. B. They can be used for many other things.

C. They are a risk to the environment. D. They are cheap to make.

3.According to the article, we can know that bottled water is __________.

A. no problem for the environment B. more expensive than tap water

C. always safer than tap water D. better for babies

4.Which of the following about tap water is NOT mentioned in the article?

A. There are a lot of problems storing tap water.

B. Bottled water can be just tap water in a bottle.

C. It may be better for your teeth.

D. It may contain fluoride.
