Question

---Excuse me，do you know______yesterday？
---Sure．It closed at 6：00 p．m．yesterday．（　　）

A. when the bookstore closes

B. when does the bookstore close

C. when the bookstore closed

D. when did the bookstore close

Answer 1

答案：C．
根据Do you know可知，本题考查宾语从句，宾语从句中一般为陈述语序，选项BD是疑问语序，所以排除掉；再根据It closed at 6：00 p．m．yesterday，可知这里表示的是时间，而且是一个过去的时间，所以宾语从句的引导词是when，时态应该用一般过去时．故选C．
