One day they went on a train journey together.
“We’ll need some food,”Pearl said.

It was not long before they were hungry.
Pearl took out the bananas and gave one to June. Then she peeled(剝)the skin of her banana and took a large bite of it.

On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could 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 Matthaci 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(限制)in use.
【小題1】When did we first know why we look like other people m our family?

A.In 1860B.In 1953C.In 1961D.In 2000
【小題2】What does the underlined word “ genes” mean?
A. The “map” of DNA.                B. A special language.
C. Small parts of DNA.                D. DNA
【小題3】What did the two scientists first discover in 1961 ?
A. The “map” of DNA.               B. A new illness.
C. The language of DNA.              D. A message of DNA.
【小題4】What can we do if we understand some “ words” of the language inside the body
A.Make people get new jobs.
B.Make medicine for illnesses.
C.Make maps of human.
D.Make people less attractive.
【小題5】What do people think about this work’?
A.It can cause good or bad results.
B.It can cause only good results.
C.It can cause good results but won’t work.
D.It can cause only bad results.

In May, 1976, Gaynor was a nine-year-old girl and lived in North Wales. One day, on her way home from school, she saw a silver(銀色的)object(物體)in a field not far from her home. The object looked like a saucer.

Gaynor was very scared. She stayed behind the tall grass and watched the door of the strange object open. She saw two aliens wearing silver suits get out. Then they used something to examine(檢測)the ground. They were short and had pink eyes. After about thirty minutes, the two aliens went back into the object. Then it took off.

When Gaynor got home, she told her mother about this unusual experience, but her family decided to keep quiet about it. They didn’t want others to laugh at their daughter.
