夏天晚上睡觉前，我总要喷些驱蚊喷雾来防止蚊子叮咬。

Before going to bed in summer, I always spray some repellent to keep ___mosquitoes from biting me.

晚上别忘了关窗，不然蚊子会飞进来叮我们。

Don't forget to close the windows at night, or ___mosquitoes will fly in and bite us.

这些不断的推销电话就像烦人的蚊子一样让人无法忍受。

The never-ending sales calls are like ___mosquitoes that just won't leave me alone.
