根据短文判断正(T)误(F).

     Jimmy and Tommy were good friends. They both attended the same class in a school. Tommy

was a clever boy. He could answer questions cleverly in class. He was quick at thinking. It seemed

that everything was easy to him. He never seemed to work hard. He spent much time on football or

other games.

     Jimmy was not so clever as Tommy. He was slow in his work. But he was hard-working. He

worked hard and steadily (扎实地) at his lessons day after day.

     In the final examination of the term, everyone thought Tommy would be the first in the class. But

it was wrong. The slow but hard-working Jimmy got the first place.

     Although Tommy was quick and clever, he did not work hard, so he could not get the first. Jimmy

was just different. He was slow but hard-working. So he did well in his lessons.

     The story tells us that one cannot depend on (依靠) one's cleverness. One still has to work hard

and steadily at one's own subjects or work.
