题目内容
--- It’s the fourth time that heavy smog(雾霾) has hit the city this month.
--- It’s high time we _______ measures to fight air pollution.
| A．will take | B．took | C．to take | D．taking |
B
解析试题分析：考查动词时态。句意：--这是雾霾天气在这个月中第四次侵扰这座城市了。--到了我们采取措施消灭空气污染的时候了。“It is high time +that 从句”是固定句型“到了做某事的时间了”从句中用一般过去时或者should +动词原形；表示虚拟语气，所以B选项正确。
考点：考查动词时态。
