There are four different species of swallow which visit us-the swift, the chimney swallow, the house martin, and the sand martin.

我们见到的燕子有四种——褐雨燕、烟囱雨燕、家燕和崖沙燕。

Chimney swallows were darting swiftly across the yard, and chickens, ducks and turkeys were waddling and strutting and straggling in from the fields.

家燕轻快地在院场上空飞来飞去，小鸡、鸭子和火鸡都纷纷从田地里回家来了。
