DNA is the whole “map” of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time, In1860, Mr Mendel discovered why we look the same as other people in our family. It is because of small things called “genes”(基因) in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages . They’re written in the DNA with a special language.
In1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell﹙细胞﹚to build its parts. So far, scientists have 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 to save people from several illness. So the more we understand, the more doctors will be able to do.
Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more “words” and find out more information, we will use it in the wrong way, just to make people more attractive (有吸引力的)，or stop sick people getting jobs.

Like most cultures around the world, the Zulu people of Africa tell stories that have animals as heroes. These stories are meant to have fun, but they are also used to teach important lessons to children. This is one of those stories.
One hot afternoon, Jackal was walking along the rocky road sniffing (嗅) the ground. He was hoping to smell a mouse or a lizard (蜥蜴), or something else that would be good to eat. He was so much lost in sniffing that he wasn’t really paying attention to what was around himself.
Suddenly, Jackal looked up to see his neighbor, Lion, walking straight toward him. He did not have enough time to run way. Jackal had played many tricks on Lion over the years, so he knew he would be in trouble if he was caught. Jackal needed to think of something quickly.
“Help! Help!” cried Jackal as he quickly jumped upon a large rock hanging over the road. “The rocks are falling down, and I can’t hold them much longer. We shall both be crushed (压碎) if you do not do your best to hold these rocks back, Lion”
At once, Lion pushed his strong shoulder against the rocks to keep them from moving any further. “I’ll just run over here to get something to stop the rocks.” shouted Jackal as he ran way to safety.

Once there was a parrot on sale in a pet store. It was a beautiful red and blue bird. It sat on a perch ( 横杆 ) in the middle of the store, so that everyone could see it when they came in. The owner was very proud of it and asked a high price for it.
One day a man went into the store. “ That’s a beautiful bird,” he said to the owner, “ But why is it so expensive? Is it an unusual bird?”
“ No, it’s not very unusual. It’s expensive because it can talk.” the pet store owner said.
“ I see. How can I make it talk?” the man asked.
The owner asked him, “ Do you see those strings ( 细绳 ) tied to each of the bird’s legs?
“ Yes,” the man answered.
“ Well, you pull those strings,” the pet store owner told him. That will make the parrot talk.”

Almost every Chinese person can recite the two lines of the famous poem,“ Every grain on the plate comes from hard work ( 谁知盘中餐，粒粒皆辛苦).”But sadly, many of us don’t actually get the real meaning of these lines: Don’t waste food.
A CCTV program, News One Plus One, reported that the food Chinese people throw every year is enough to feed 200 million people for a year.
Do we have too much food ? Of course not. According to the UN World Food program, there were 925 million hungry people around the world in 2010, especially in developing countries. Six million children die of hunger every year.
The Chinese people are well known for being hospitable ( 好客的 ) and generous ( 慷慨大方 ). Many even feel that they lose face if their guests have eaten all the food on the table.
Luckily, a number of people have realized the importance of saving food. Last November, Li Hong, a waitress in a restaurant in Nanjing, got fired because she took some leftover food home for her son. Many people stood by her side and criticized ( 批评 ) the waste of food.
What should we do in our daily life to waste less food ? Here are some tips :
Do not order too much in a restaurant. Only order as much as you want to eat. If you can not eat all the food you ordered ,take the rest of it home.
Don’t be too picky ( 挑剔的 ) about food . Some food may not taste great, but your body needs it.
Keep an eye on what food you have at home. Don’t buy too much, especially for vegetables and fruit.
