Question

用所給動詞的適當時態填空

－Listen! What ________ they ________(do)?

－They ________(sing) songs.

－Then what ________ they ________ (do) this afternoon?

－They ________ (buy) something for Mr Li.

Answer 1

答案：
解析：

are, doing; are singing; are, going to do; are going to buy 　　Listen“聽”，提示了句中的動作正在進行，前兩句應該用進行時。Then后面的句子其時間狀語是this afternoon，說明動作還沒有發生，用be going to句型。
