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. Plans have genes. Animals have genes. Yo
u 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 w
hat 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 co
mes 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 celIs. 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. What is DNA?

China is a land of bicycles. At least it was back in 1992 when I traveled the country. Back then everyone seemed to be riding a bicycle. Millions of them, all black. Cars were rare. Yet since my arrival in Beijing last year, I’ve found the opposite is true. There are millions of cars. However, people still use their bicycles to get around. For many, it’s the easiest and cheapest way to travel today. Bicycles also come in different colors--- silver, green, red, blue, yellow, whatever you want.
It’s fun watching people biking. They rush quickly through crossroads, move skillfully through traffic, and ride even on sidewalks(人行道). Bicycles allow people the freedom to move about that cars just can，t provide.
Eager to be part of this aspect of Chinese culture, I decided to buy a bicycle. Great weather accompanied my great buy. I immediately jumped up on my bicycle seat and started home.
My first ride home was orderly (守秩序的). To be safe, I stayed with a “pack”of bikers while cars on the streets came running swiftly out of nowhere at times. I didn，t want to get hit. So I took the ride carefully.
Crossing the streets was the biggest problem. It was a lot like crossing a major highway back in the United States. The streets here were wide, so crossing took time, skill and a little bit of luck.
I finally made it home. The feeling on the bicycle was amazing. The air hitting my face and going through my hair was wonderful. I was sitting on top of the world as I passed by places and people. Biking made me feel alive.According to the author, why are bicycles still popular in China today?
| A．Because they are traditional and safe. |
| B．Because they are convenient and inexpensive. |
| C．Because they are colorful and available. |
| D．Because they are fast and environment friendly. |

“I don’t like my parents. They always tell me I should do this, and should not do that. It sometimes makes me angry,” said Li Ping, a middle school student in Hunan. Do you have the same problem? Perhaps your parents had the same problem when they were your age long ago. Why does it seem that some parents are not so friendly in their children’s eyes?
One of the biggest things is when someone becomes a parent, he / she likes worrying things. They worry about everything about you, from the time you were born. They do a lot for you, though something would make you angry, because they care about you and worry about you. They worry about your choice of friends, the food you eat, your work at school, how much sleep you get, etc. All these things are part of your life. They want you to grow up healthily and happily.
So how can you make things easier on yourself? It’s easier than you think. Just make sure your parents know what you’re doing. Get them to know your friends. Phone if you stay somewhere else so that your parents don’t call every hospital in the phone book looking for your body. Say sorry to them when you make mistakes. Take responsibility (责任) for what you have done. Talk about your ideas with them. They may talk about theirs with you.
Most of all, try to think about why your parents do this or do that. They are still practicing being parents and need help you can give them. Someday, when you become a parent, they may be able to help you know how to get on with your children.What does the writer think we should do if we go back home later than usual? We should ________.

An earthquake is a trembling or shaking of the ground caused by the sudden release(释放) of energy stored in the rocks below the surface. Generally, earthquakes last only seconds. Strong ground shaking during a medium（中等的） to large earthquake generally lasts about 10 to 30 seconds. Aftershocks（余震） can occur once in a while for weeks or even months.
Many people think that there is an “earthquake season” or a kind of “ earthquake weather ”.As a matter of fact, there isn’t. Earthquakes can occur at any time of the year and at time of day or night. Earthquakes occur under all weather conditions-sunny, wet. or cold without any special weather tendency(倾向).
Also, you don’t need to worry that the ground will open up and swallow people when earthquakes occur. Open ground cracks may form during an earthquake, for example, to land sliding or ground falling. However, such cracks tend to be open gaps (they don’t “ swallow”) that a person could stand in afterwards.
The safest place in an earthquake is an open field because buildings and falling objects can injure or kill you. If you are indoors, when you feel the ground start to shake, take cover immediately under a table or strong piece of furniture, placing something between falling objects and yourself. Don’t “ attempt to use the stairs or an elevator to get out of the building..Which of the following is TRUE according to the passage?.
