The mouse is a most effective device used by people to communicate with a computer.

　　For most people, it’s almost impossible to operate a computer without a mouse, let alone surf the Internet. A well-chosen mouse is really handy, flexible and convenient in controlling the screen. With the functions of inserting, deleting, moving and copying, it enables us to edit test, browse web page and download what we want. It can even bring us a flood of music, movies and PC games. Just imagine, all this can be done with a cute mouse.

　　A convenient tool can certainly make our work easier, but it doesn’t always help in a positive way. Too much ready information on our fingertips leaves little room for knowledge pursuing. Too many ready answers make us less excited in finding truth. Relying too much on mouse clicking makes us lazier and less creative both mentally and physically.

　　Dear teacher and schoolmates,1t’s a great pleasure for me to be today and share my experience of learning English with you.I'm interested in English and hope to be an interpreter in the future.Naturally lt’s very important for me to learn English well .As everybody knows vocabular is an important part of language, just like bricksin a building .I usually memorize twenty new words a day and put them to use whenever possible . After class.I often listen to English programs on TV and on the radio .Besides ,I've learned a lot from the Internet and other sources.

　　Now.I'd like to make some suggestions on English teaching and learning in our school.Firstly ,we should be given more opportunities to use what we’ve learned ln order to have a better grasp of it.Secondly.I hope our teachers can recommend more interesting books and magazines and give us more free time to read them. Finally，1 suggest we have more Endish activities，such as English contests and festivals.

　　Thank you for listening.
