【題目】
On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could now read the whole “map” of the human body: DNA. DNA is something that everybody has, and it tells the body what to do. DNA is the reason that we look like our mother and father, 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, Gregor Mendel discovered a special reason why we look the same as other people in our family. It is because of small things named “genes” in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written in the DNA with a special language.
In 1961, Marshall Nirenberg and Johann Matthaei found a message in DNA showing how DNA tells the cell (細(xì)胞) to build its parts. Scientists have now 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 save more people from several illnesses.
Most people hope that this will help make better medicine and help sick people. Other people worry that when people begin to know more words and find out lots of other information, we might use it in a wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have to meet a lot of trouble if DNA technic wasn’t limited in use.

World Water Day is on 22 March each year. It started in 1992. Its goal is to get people and Governments【1】 one of our most precious resources. For human beings, water not only is an important resource to survive and grow, but also offers fun and pleasure. Could you imagine what the world would be like【2】 water?
Nowadays, we are facing an【3】number of environmental crisis(危機(jī))such as water pollution and water shortage. In India's capital, New Delhi, millions do not have any running water.
Even in richer neighborhoods, young and old wait hours for clean water. One young woman in Ghana, like many in Africa, Asia, Latin America, and elsewhere walks kilometers for water."I have to collect for my family five times a day."
Something must be done to save and protect water【4】. The special day is a day for us to know about what we have done and what we should do. I believe the environment will become better and better if we follow the spirit of the World Water Day.
