Dear Editor，
I am writing to tell you about the survey I've made on"Using paper cards or e-cards？"in our class．
About 30% of the students want to use paper cards．First of all，they are made by hand and they can express people's real feelings．Second，they are easy to take and can be kept for long．Third，people can read them without computers．However，around 70% of the students prefer to use e-cards．For one thing，e-cards can carry lots of information and people can send them quickly．For another thing，using e-cards can save paper so that our environment can be protected well．What's more，people can make various designs they like．
I think we'd better use e-cards more to save natural resources．But on some particular occasion，we can also use paper cards to show our real feelings．
Yours sincerely
Wang Qiang．
