六、阅读理解
Many scientists once believed that physical similarities between identical twins are genetic(基因的), while their personalities, intelligence and other differences between them are an effect of their environment. Now scientists are discovering that the boundaries(界限)between genes and environment are not so clear.
　　Twins Jim Springer and Jim Lewis were adopted as babies and raised by different couples. When the Jims finally met at age 39, they discovered they had plenty in common. Both were 6 feet tall, 180 pounds. They had the same smile and the same voice. When scientist Thomas J. Bouchard Jr. invited the Jim twins to his lab, people there found it very hard to tell them apart.
　　But the similarities didn't stop at the physical level. They'd both had dogs named Toy. They had both married women named Linda. They'd both been policemen, enjoyed music, and left love notes around the house for their wives. They had so much in common, it seemed unlikely these were just coincidences (巧合).
　　The Jim twins were just one of 137 sets of separated twins Bouchard tested. When they compared the twins' IQ scores, Bouchard and his team reached a surprising conclusion. They concluded that intelligence was mostly connected to genes rather than to training or education. It seemed the differences in family and environment had little effect.
　　However, genes can't control everything, argues geneticist Danielle Reed, who also studies twins. Reed's research shows that though nothing can truly change our DNA, environmental differences that a child experiences before birth and in their first year can sometimes affect the way the DNA behaves, making even identical twins into very different people. "What I like to say is that Mother Nature writes some things in pencil and some things in pen,"she explains."Things written in pen you can't change. That's DNA. But things written in pencil you can."
1. How many physical similarities between the Jim twins are mentioned
A. 2.　　　B. 3.　　　C. 4.　　　D. 5.
2. What did Bouchard's study find about the twins
A. Each seemed to be as tall as their twin.
B. Each had the same hobby as their twin.
C. Each had almost the same ability as their twin.
D. Each had about the same IQ level as their twin.
3.What is Reed's opinion about genes and environment
A. Only DNA has an effect on our development.
B. Environment could possibly change some things about us.
C. There are no boundaries between genes and environment.
D. Environmental differences can sometimes change our DNA.
4. What is the passage mainly about
A. The way the DNA behaves.
B. The similarities between the Jim twins.
C. The connection between intelligence and families.
D. The effects of genes on personality and intelligence.
