下面一句填什么介词?on 还是 in?
______ rainy days we stay at home.
除了 days 还有 nights, mornings, afternoons, evenings 前呢?用什么介词?
陈老师:
▲用介词 on(其后的 days 用复数表经常性):
On rainy days we stay at home. 下雨天我们呆在家里。
▲类似的例子如:
The car has an inclination to stall on cold mornings. 这辆汽车天冷时早晨常常熄火。
On Sunday afternoons, we like to go for a sail on the lake. 星期日下午,我们喜欢到湖上乘船航行。
On dark nights children should wear reflective clothing. 在漆黑的夜晚,儿童应该穿可以反光的衣服。
▲但是,in the mornings, in the afternoons, in the evenings 用介词 in(这类用法里用复数表经常性)。如:
He works best in the mornings. 他早晨工作效率最高。
I like to sit back and rest in the evenings. 我喜欢在晚上什么也不做, 好好休息。
