A．was increasing?? B．has increased

C．had increased?? D．will be increasing

 

Answer 1

【答案】

B

【解析】選B。題干的意思是：“在過去的三十年里，參加健身計劃的人數(shù)急劇增加。”由時間狀語during the last three decades可知，本句要用現(xiàn)在完成時態(tài)，所以正確答案為B項(xiàng)。注意對現(xiàn)在完成時態(tài)的時間狀語in/during/over the last/past ten years，so far，since...等的積累。
