Water is the "life blood" of our earth. It is in every living thing. It is in the air. It runs through mountains and valleys. It forms lakes and seas. Nature has a great water system（系统）.Rainwater finds its way to rivers and lakes. River water runs into the sea. At the mouths of the rivers, fresh water joins the salt water of the sea.

A small cloud moves slowly through the air in a hospital operating room （手术室）.In the room a patient with cancer（癌症），lies on a table.The cloud is all around the patient，covering her body and filling her lungs（肺）.The cloud is not smoke.It is made of millions of nano﹣robots（纳米机器人）.These tiny robots move from cell （细胞） to cell in the patient's body，killing the cancer.
Fighting cancer with nano﹣robots is only an idea today，but scientists say that it could be possible in the future.Using nano﹣robots for good purposes such as fighting the illness or repairing the environment may be the way to many of today's problems.
However，nano﹣robots could be a dangerous risk as well.Because nano﹣robots are so tiny，they will have to work in large teams of many thousands to many millions.For this reason，nano﹣robots will have to be programmed（被编程）to build themselves.Scientists will not have the ability to build millions of nano﹣robots one by one.
This ability to re﹣produce is making some scientists worried.What will happen if something goes wrong in the programming？Quite a lot of crazy nano﹣robots would be far worse than any illness.Some people think that if they get out of control，nano﹣robots could make the Earth gone.
What should be done？Should we continue researching nano﹣robots or should we search for other methods？This is one of the many difficult decisions that we have to make in the future.

Last Saturday，I went to a coffee shop to meet a friend of mine.I got there ten minutes earlier.
So I ordered a cup of coffee and sat by the window，watching people.There were some boys playing football on the street and a small boy was running after the ball as it rolled across the road.

Have you heard of Peter Pan？Peter Pan was a magic character.He first appeared in Wendy Darling's room and searched for his lost shadow（影子）.And Peter Pan has been very famous around the world ever since.The story was created by J.M.Barrie.Do you know how J.M.Barrie created it？
J.M.Barrie was born in Scotland in 1860.He moved to London and became a writer in 1885.Twelve years later，he became friends with Sylvia Davies and her five sons.He enjoyed telling the boys stories and made up the character of Peter Pan to bring them pleasure.He said Peter Pan was based on all the boys，telling them，"That is all Peter is ﹣the spark（创作灵感） I got from you."
A play about Peter Pan was written and shown in December 1904.It was a great success.In 1911，J.M.Barrie wrote a book，Peter and Wendy.The book has been popular sine it was printed for the first time.J.M.Barrie invented the name Wendy，based on Fwendy，the name that he was given as a child.The name Fwendy was based on the word"friend".

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 similar to 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 real messages.They are 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.So far，scientists have found all the words in the DNA map，but we 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 to 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.
