Question

they planted lots of trees last year

Last year lots of trees _______ to make our campus more beautiful．（　　）

A. is planted

B. was planted

C. are planted

D. were planted

Answer 1

答案；D 考查时态辨析．根据题干中的last year，可知时态是一般过去时，句中动词要用过去式，故先排除A、C．句中主语lots of trees 是复数形式，根据句意是被栽了，故用的是被动语态：be+过去分词，故选择D．
