2.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 I860,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 they could understand in that language.It shows how DNA tells the cell (细胞)to build its parts,(有几个单词看不清) 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 wc Icam 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.

| ※When parents get angry,it isn't the time to get angry back.A lot of times they're not upset with you,but with their boss,the neighbor,or the price of vegetables.You just happen to be there at the wrong time.Look hurt?Get out of the way when they're in a bad mood.They need some time and space.Go outside,to a friend's house,or to your room.At last they will become calm and miss you. |
| ※If you have trouble talking to your parents,or if they get angry every time you try to discuss something,write a note.Put it on their bedside table.Parents are easily moved by notes like this and will probably keep them forever. |
| ※Do not create situations where there is a winner and a loser.You're the child and will probably lose most of the time.How many times have you grounded your mother or taken away the phone privileges(特权) from your dad?Try to compromise with each other and work out a situation where both of you win. |
| ※Ask your parents once a day,"Is there anything I can do for you?"Most of the time they will probably say no,or give you something that will take a few minutes to complete.Your parents will love this and see you as a very cooperative(可合作的) person.When this happens,they will probably be more cooperative with you.You could also surprise them by doing something they don't make you do.They'll tell everyone you are the best possible son or daughter and,what's more,they will believe it. ※Click for more information at the red icon on the left. |
