Have you ever heard a news reporter talk about DNA?Reporters talk about DNA found at the scene of a crime.They talk about police finding DNA “fingerprints”.Police sometimes use DNA as a clue to find out who committed the crime.
DNA is a substance(物质)that makes up genes.Everything alive has genes.Plants have genes.Animals have genes.You have genes.
Genes are the basic units of heredity(遗传).Heredity means all the characteristics you inherit from your parents.You get your genes from your parents.You inherit half of your genes from your mother.You inherit half of your genes from your father.
Genes are a kind of code.A tree’s genes tell what shape its leaves will be.A cat’s genes tell what color its fur will be.Your genes tell what color your eyes will be.Your genes tell what color your hair will be.Everything about you comes from the code in your genes.
Genes line up on strands(链)called chromosomes(染色体)in cells.Everything alive is made up of cells.Chromosomes are in the center,or nucleus of cells.
Different parts of you are made of different kinds of cells.Your muscles are made of muscle cells.Your skin is made of skin cells.The code in your genes tells your body to make different kinds of cells.The genes in each cell tell the cell how to work.They tell the cell when to make new copies of itself.
An Austrian monk named Gregor Mendel first saw inherited patterns in pea plants.He experimented with pea plants in the 1860s.One of the things,or traits(特质) Mendel studied was what makes some pea plants tall and some short.He said that the traits must come from units of heredity passed from the parent plants.These units were later called genes.
In the mid-1900s,scientists discovered that genes are made of DNA.In the 1970s,scientists learned how to change DNA with genetic engineering.Scientists also learned that problems with certain genes cause diseases.Muscular dystrophy,cystic fibrosis,and hemophilia are some genetic diseases—diseases caused by problems in genes.Today,scientists are looking for ways to cure genetic diseases by changing genes through a process called gene therapy.

Have you ever noticed what happens to an idea once you express it? Just talking about it or writing it down causes you to make it clear in your own mind. How can you use this to increase your brain power? Start writing.
By putting thoughts into words, you are telling yourself the logic (逻辑) behind what you think, feel, or only partly understand. Often, explaining a thought is the process of understanding. In other words, you increase your brain power by exercising your “explain power.”
Try this experiment. Explain how you’ll increase your brain power, even if you have no idea how right now. Just start with anything, and create an explanation. For example, start with “I’ll learn chess,” or “I’ll read an article on the mind every week.” Explain how that will help. You’ll be surprised how often this becomes a workable plan, and if you actually do this, you’ll have a better understanding of your brain twenty minutes from now.
Another benefit of writing is that it helps you remember. Many, if not most, highly productive people are always taking notes. You can try keeping it all in your head, but if you keep a journal of your ideas the next time you’re working on a big project, you’ll probably have more success.
Want to understand a topic? Write a book about it. That’s an extreme example, but if you are learning something new, write a letter to a friend about it, and you will understand it better. Want to invent something? Write an explanation of the problem, why you want to solve it, and why it is worth solving, and you’re half-way there.
Writers don’t always write because they clearly understand something beforehand. Often, they write about something because they want to understand it. You can do the same. Writing will help bring you to an understanding. Give it a try.
1.What would be the best title for the text?
A. A Way on How to Write
B. Increase Your Brain Power through Writing
C. Brain Power Helps Improve Your Writing
D. How to Start Your Writing
2.If a writer writes something, it means that he or she _______.
A. has understood it very well
B. needs to understand it better
C. wants to remember it in his or her mind
D. is exercising his or her “explain power”
3.The underlined sentence “you’re half-way there” in the fifth paragraph implies that ______.
A. you are already successful
B. you still need to work hard
C. writing can help you walk half way
D. you have been on the way to success
4.What’s the main purpose of the writer writing the text?
A. To advise readers to start their writing.
B. To explain the importance of writing.
C. To persuade readers to become writers.
D. To increase readers’ brain power.
