Big Brothers Big Sisters is based on the simplicity and power(力量) of friendship.It is a program which provides friendship and fun by matching vulnerable young people (ages 7-17) with a volunteer adult who can be both a role model and a supportive friend.

Volunteer tutors come from all walks of life—married, single, with or without children. Big Brothers and Big Sisters are not replacement parents or social workers. They are tutors: someone to trust, to have fun with, to talk and go to when needed.

A Big Sister and Little Sister will generally spend between one and four hours together three or four times each month for at least twelve months. They enjoy simple activities such as a picnic at a park, cooking, doing sports or going to a football match. These activities improve the friendship and help the young person develop self-respect, confidence and life direction.

Big Brothers Big Sisters organizations can be found throughout the world. It is the largest and most well-known provider of tutor services internationally and has been operating for 25 years.

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. In 1860, 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.

In 1961, another two scientists found the first “word”that 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 illnesses. 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.
