now and then

偶尔；有时中释

1 This section of the road is so norrow that there are bound to be traffic jams now and then..这段路太窄， 交通有时不免堵塞。

2 If they are being honest, they will tell you they barely have the time, energy, and budget to help much beyond a pat on the back now and then..如果他们说实话，就会告诉你除了偶尔在你背上拍一下表示赞许外，他们几乎没有支持实现新思想的时间、精力和预算。
