題，所以人稱應該以第三人稱為主。謀篇DearEditor，Recentlyourclasshashadadiscussionaboutwhetherseaexplorationshouldbecarriedout.Someofthestudentsareinfavourofseaexploration.Theysayseaexplorationhasmadeitpossibleforpeopletodiscovernewmedicinesaswellasnewsourcesoffoodandenergy.Othersareagainstit.Althoughseaexplorationmighthelpimproveourunderstandingofthelifeontheearth,itmightbringaboutmarinepollution,whichfinallyleadstheoceancreaturestodeath.Italsomightcauseecosystemdestruction.Personally,seaexplorationshouldbebalancedwitheconomicneeds.Hopefully,astechnologyimproves,wemayhavemoreoptionsformanagingthisbalance.Onepossibleversion假定你是某校的宣傳委員李華，應邀為學校網站英文版寫一篇有關海洋生物保護的文章，請根據(jù)以下要點寫一篇短文。1.海洋受污染的現(xiàn)狀;2.保護海洋的重要性。注意:1.詞數(shù)100左右;2.可適當增加細節(jié)，以使文章連貫。________________________________________________________________________
