How important is keeping healthy to you? A group of young people got together to discuss this
question. Here"s part of their discussion.
PETER: I"d like to stay healthy, but to be honest, I only eat food that tastes good. And if food tastes
good, it"s usually bad for you, isn"t it? Cola tastes better than water, for example.
TONY: Well, food that is bad for you can taste good! But I prefer not to eat much food that is fried,
like, er, French fries. Do you eat fast food, Laura?
LAURA: Do I eat fast food? Never! I love to eat food that is healthy. I want to take care of my health,
so I eat mainly fruit and vegetables. Oh! And I stay away from sugar, you do too, don"t you?
TONY: Hm, yes. And I think most people are in agreement that fruit and vegetables are good for health.
But, um, I would say that fast food itself isn"t always bad for you, but too much of it is not good.
LAURA: Actually, did you know that it"s been found in laboratory testing that some types of oil are really
bad for us? So I don"t eat anything that"s been cooked in oil. Also, did you know that some foods might
cause cancer? Like burnt barbecued meat. I"ve heard eating burnt food like this can increase (增加)the
risk of cancer.
PETER: Really! But I love to eat meat that"s well cooked, even if it is a little burnt. It"s delicious, and
meat isn"t really dangerous, is it?
LAURA: Oh! Yes, it is! I never eat meat. It"s not at all good for our health. If I were you, I"d eat nuts
instead.
TONY: Well, I agree it"s good to eat lots of fruit and vegetables, but I think it"s also fine to eat some
meat or fish. People who eat a balanced diet should be healthier than those who only eat biscuits and
hamburgers, shouldn"t they? I prefer to only eat food that I like, but isn"t it important to eat food that"s
healthy, even if you don"t like it? The main thing is to have a good balance. |

You may look it up in the English-Chinese dictionary. It will tell you a lot about the word: the pronunciation, the Chinese meaning and how to use the word.

in ordinary water.
Materials : 3 clean iron nails ( 铁钉) ; test tubes ; test tube holder ; cotton wool ; oil ; Bunsen burner. | Iron in dry air
Method
(1)Put some iron nails at the bottom of a test tube.

there is no air in the water.
Put two or three clean nails in the water. | (4)Add some oil to the water. ( This will keep
air out of the water.)
(5) Leave the tube for one week.
Result

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. | | 根据短文内容，选择最佳答案。 | | 1. When did we first know why we look like other people in our family? | A. In 1860.
