TOEFL academic 对话（我的伤心地），跟这个材料是比较吻合的，对广大英语学习者，特别是考托福的同学很有帮助，最近没人做这个东西了，我弄一下。

It’s one of the oldest moves in teen dating. Head to a scary movie. As soon as the scary music kick in, your date cuddles closer for comfort. Well, some birds may have the same idea. Splendid fairy-wrens are small, sexually promiscuous birds native to Australia. It turns out that males get the attention of potential mates by making their move after a predator announces its presence. The research was published in the journal Behavioral Ecology. [Emma Greig and Stephen Pruett-Jones, Danger may enhance communication: predator calls alert females to male displays
[Bird sound] That’s the sound of butcherbirds, which prey on splendid wrens. Every time male wrens hear that cry, they sing this in response [wren sound]. Researchers say the calls become layered atop one another, almost like a duet.
The scientists tested the response of female wrens by playing recorded bird calls. They played just the male fairy-wren call. Then they played the trill of the wrens singing immediately after the butcherbirds. The females became significantly more alert—looking to the sound or singing in response—after hearing the two calls together than they did if they heard just the wren. And so for both teens and wrens, a bit of fear might help a guy get the chick.
