Dear Mr. Barone,
    As we know, our traditional seventh-grade spring field trip is to the State History Museum. This year, we would like to visit the new World Botanical Gardens located in East Johnsonville. The garden hours are from 10: 00 a .m. to 6:00 p.m. The class could leave school at 8: 00 a .m. and arrive just as the gardens open. We would explore the gardens, make notes about our favorite exhibits, and return to school by 5:00 p.m.
    Many seventh-grade students have already visited the history museum. Since it is so close, students often go there with their families. We have enjoyed the interesting exhibits, but this year we are hoping to learn something new. The purpose of the field trip is to help us understand the different environments of our planet. The World Botanical Gardens contains the second largest walk-through Amazon rainforest exhibit in the country.
    Since seventh-grade students study plants and plant energy in science class, visiting the botanical gardens would be an educational field trip. The information we could learn there would be an excellent way to supplement (补充) our science studies. We would observe plants growing in special displays that are similar to their natural habitats. Charts located near each display provide information about the plants. It will help us a lot when we learn about topics such as how food webs work and how plants respond to light.
    In addition, the field trip supports what we are studying in our English class. We are now reading Which Way to the Amazon? This novel, which is set in a rainforest and based on scientific facts, describes the adventures of an expedition (探险队) searching for a lost city. The rainforest exhibit at the World Botanical Gardens would better help us understand the novel's setting. Please consider this request for the seventh-grade field trip to the World Botanical Gardens.
    Thank you very much.
Sincerely,
Robert Burns
Seventh-Grade Class President
