English is important in the world。 So most people speak English as a second language， and English is used around the world for computers， and it is used in science， too。
I have been learning English for five years， and I really love it， but learn English have a lot of difficulty。 If you want to improve your English， you should take lots of grammar notes in every class， and watch movies， listen to pop songs。 If you find pronunciation is difficult， you should make up conversations。
If you also think native speakers talk too quickly， you should speak English with your friend in class。 Try your best to learn English， you will make progress!
