All students need to have good study habits. When you have good study habits, you learn things quickly. You also remember them easily.

Do you like to study in the living room? This is not a good place because it is usually too noisy. You need to study in a quiet place, like your bedroom. A quiet place will help you only think about one thing, and you will learn better. Before you begin to study, do not forget to clean your desk. A good desk light is important, too. It’s good for your eyes if there is enough light.

       On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they
could now read the whole "map" of the human body: DNA. DNA is something that everybody has, and
it tells the body what to do. DNA is the reason that we look like our mother and father, because we get
some of their DNA to make our own.
       People have been trying to understand the human body for a long time. In 1860, Gregor Mendel
discovered a special reason why we look the same as other people in our family. It is because of small
things named "genes" in our body. In 1953, James Watson and Francis Crick made another discovery
and found out that those small parts are real messages written in the DNA with a special language.
       In 1961, Marshall Nirenberg and Johann Matthaei found a message in DNA showing how DNA
tells the cell (细胞) to build its parts. Scientists have now found all the words in the DNA map, but we
still do not understand what they all do. By understanding what just one "word" means, we can help
save more people from several illnesses.
       Most people hope that this will help make better medicine and help sick people. Other people worry
that when people begin to know more words and find out lots of other information, we might use it in a
wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have
to meet a lot of trouble if DNA technic wasn’t limited in use.
