A Strange Greeting, a True Feeling.Last week I was invited to a doctor’s meeting at the Ruth hospital for incurables. In one of the wards a patient, an old man, got up shakily from his bed and moved towards me.I could see that he hadn't long to 1 , but he came up to me and placed his right foot close mine on the floor.

But as soon as he saw me he came running and placed his right foot against mine. After that, his 20 to me was always the same.

DNA is a substance that makes up genes.Everything alive has genes. Plants have genes. Animals have genes. You have genes. Genes are the basic units of heredity. 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 called chromosomes in cells.Everything alive is made up of cells.Chromosomes are in the center, or nucleus, of cells.
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, Mendel studied was what makes some pea plants tall and some short. He said that the traits (特征) must come from units of heredity (遗传)passed from the parent plants.These units were 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 altering genes through a process called gene therapy.

As prices and building costs keep rising, the “do-it-yourself” (DIY) trend in the US continues to grow.
“we needed furniture for our living room,” says John Ross, “and we just didn’t have enough money to buy it. So we decided to try making a few tables and chairs.” John got married six months ago, and like many young people these days, they are struggling to make a home at a time when the cost of living is very high.The Rosses took a 2-week course for $280 at a night school. Now they build all their furniture and make repairs around the house.
Jim Hatfield has three boys and his wife died.He has a full-time job at home as well as in a shoe making factory.Last month, he received a car repair bill for $520.“ I was deeply upset about it.Now I have finished a car repair course, I should be able to fix the car by myself.”
John and Jim are not unusual people. Most families in the country are doing everything they can to save money so they can fight the high cost of living.If you want to become a “do-it-yourself”, you can go to DIY classes.And for those who don’t have time to take a course, there are books that tell you how you can do things yourself.
