We are often warned by our teachers not to waste time because time（1） will never return. I think it quite（2） . What does time look like? Nobody knows, and we can' t see it or touch it and no amount of money can buyit. Time is（3）, so we have to imagine it.

Time passes very quickly. Some students say they don't have（4）time to review their lessons. It is（5）they don't know how to make（6）of their time. They waste it in going to theaters or parks, and doing other（7）things. Why do we study every day? Why do we work? Why do most people have to take buses instead of （8）. ? The answer is very easy. We wish to save time because time is priceless.

Today we are living in the twenty-first century. We（9） time as life. When a person dies, his life ends.Since life is short, we must（10）our time and energy on study so that we may be able to serve the people well inthe future. Laziness is the thief of time, for it not only brings us（11） , but also does other （12）to us. Ifit is （13） for us to finish our work today, let us do it today and not （14） it until tomorrow. Remember that time ismuch more（15）.

Dr. Stokoe decided to propose a study of sign language. Many other teachers were not interested , and thoughtDr. Stokoe was（2） to think about studying sign language. Even deaf teachers were not very interested in the（3） . However, Dr. Stokoe did not give up.（4） , he started the Linguistics Research Program in 1957. Stokoeand his two deaf assistants worked（5） this project during the summer and after school. The three researchersmade films of deaf people（6），The deaf people in the films did not understand（7）the research was aboutand were just trying to be nice to Dr. Stokoe. Many people thought the whole project was silly, but（8）agreedwith Dr. Stokoe in order to please him.

Stokoe and his（9） studied the films of signing. They analyzed the films and tried to see patterns in the signs.The results of the research were（10） : the signs used by all of the deaf people followed certain linguistic rules.
