Many trees and flowers _________ in our city every year.

A. planted B. are planted C. were planted D. plants

B 【解析】句意：在我們城市每年都種許多樹和花。該句的主語是Many trees and flowers和plant之間是被動關(guān)系，故用被動語態(tài)，被動語態(tài)由be+動詞過去分詞構(gòu)成，故排除A、D選項；又因every year（每年）是一般現(xiàn)在時的時間狀語，主語為復(fù)數(shù)所以be動詞應(yīng)用are，排除C選項，plant的過去分詞為planted，故答案選B。
