Everyone has traits ( 4+性 ) that make us who we are. We have physical. traits, like red hair, long legs and funny-looking toes. We also have character traits including humor, warmth, creativity and so on.
Certain physical traits are fully inherited (遗传 ), such as blue eyes and knobby knees. About 25,000 t0 35,000 genes (基因 ) are in a single cell in the human body. These genes carry the traits that are passed down genetically from parents to their children.
Many traits exist between inheritance and development - the interaction with environment.One example is body shape. It tends to be passed down from parents. But once diet becomes a factor, environment begins to play an important role in how the body develops. Body shape is a trait that is a mixture ofinheritance from parents and influence of environment.
So lots of our most important traits have been learned, rather than inherited. For example, if you're really great at video games, it's not because your parents passed down the skills in genes. It's because you have practiced a lot of video games and developed those skills yourself. If you have kids who turn out to be great at video games, it is because they put in the hours, learned the skills, and memorized
the moves that are necessary to play the video games well.
Of course, some of us have brains that are more advantageous to video game playing. Say you were born with a large and powerful part of the brain that controls your hand-eye coordination (协调能力 ).That's inherited. What you do with it, how you choose to develop that advantage, is up to you.
You can pierce your nose or get a tattoo - it doesn't matter how much you change your body during the lifetime. None of those things will turn into genetic material to be passed down to the next generation. However, if your children grow up in an enwronment with role models who are pierced and covered in tattoos, they are more likely to get piercings and tattoos!
1.is a physical trait that is fully inherited

2.According to the passage, the writer believes that
A. character traits can hardly change during the lifetime

C. a kid's hand-eye coordination isn't related to inheritance

What makes us who we are? This question has two different answers. One is the environment that surrounds us when we grow up, and the other is our genes (基因). In English, this is called the “nature vs nurture debate(辩论)”. Nature means genes, and nurture means environment, including the people around you.
There is a famous saying: “Give me a child until the age of 7 and I’ll show you the man.” Now, there is a scientific research to support this famous saying.
They watched small birds in new environments, and wrote down how much they explored(探索). Birds that grew up with very outgoing birds were more outgoing themselves. Scientists at the universities of Exeter, UK and Hamburg, Germany did studies on birds. They found that their personalities（个性） were affected most by the birds around them when they grew up – more so than genes.
Nick Royle from the University of Exeter in the UK said the research was surprising because it shows that “for these birds, personality is mainly determined（决定） by environment.” However, human personalities are a lot more complicated than birds, so there is much we still don’t know. The nature vs nurture debate will continue for a long time, if not forever.
1.The famous saying in the passage tells us _________.
A.A 7-year-old boy can do things as well as an adult.
B.An adult can be influenced and changed by a 7-year-old boy.
C.The environment in the early part of our life has the biggest influence on our adult life.
2.Nick Royle is a(n) ______ scientist.
A. American B. British C. German
3.What do the scientists think of the research?
A. Outgoing. B. Exciting. C. Surprising.
4.What does the underlined word “complicated” mean?
A. 有趣的 B. 类似的 C. 复杂的
5.Which is NOT TRUE according to the passage?
A. The environment and genes affect our personality.
B. The scientists are sure that the environment influences the human personality more than the genes do.
C. The nurture means the environment .
