根据短文内容,判断正(T)误(F)。

     Some people have very good memories, and can easily learn quite long poems by heart, while there are

people who can only remember things when they have said them over and over.

     Charles Dickens, the famous English author, said that he could walk down any long street in London and

then tell you the name of every shop he had passed. Many great men in the world have had wonderful

memories.

     A good memory is great help in learning a language. Everybody learns his own language by remembering

what he hears when he is a small child. Some children-like boys and girls who live in foreign countries with

their parents-seem to learn two languages almost as easily as one. In schools it is not easy to learn a second

language because the pupils have so little time to practice it, and they are busy with other subjects as well. 

    The human mind is rather like a camera, but it takes photographs not only of what we see but of what we

feel, hear, smell and taste. 

    Memory is the diary that we all carry about with us.

( )1. All the humans have good memories.

(     )2. Charles Dickens, the famous American writer, could remember things well.

(     )3. A good memory is of importance in your learning a language.

(     )4. Sometimes we can learn a second language without going to school.

( )5. The human mind is a good camera.
