     The US is one of the biggest countries in the world. It is well-known because its population comes

from all over the world. The immigrants(移民) can learn English to keep the United States united, but it

is unfair to have to drop their culture for an American way of life.

     I believe that recent immigrants should learn English in order to live in this country. If they don’t learn

English, they won’t be- able to communicate and do what they want. Anita, one of my mother’s friends,

came here from Ecuador（厄瓜多尔） three years ago. She does not speak English. One day her

daughter got a serious fever. She didn’t know what was going on, so she tried to call an ambulance(救

护车). However, when she called the hospital, she couldn’t talk. The operator(接线员) couldn’t

understand what Anita was saying. Thankfully, her sister arrived and called the ambulance. The doctor

told Anita that if she hadn’t arrived at the hospital in time, her daughter would have died.

    Immigrants should learn English to speak with the public, but they should also keep their language at

home. If we learn English only and forget our own language, we won’t be able to communicate with our

parents. Florence, my co-worker, speaks English only. Her mother didn’t teach her Spanish, her mother

language. She has lost her mother language, tradition and culture, so she can’t pass them down to her

future generations.

    In conclusion, immigrants should learn English in order to communicate with the public and to keep the

country united, but they shouldn’t drop their culture for an American way of life.
