When people visit Switzerland for the first time,they look with great interest,not only at the mountains but also at a type of clock—a Cuckoo-clock,on sale there．Cuckoo-clocks are very popular with tourists looking for a souvenir．A Cuckoo-clock has a small painted cuckoo that comes out near the top of the clock every half an hour and says,“Cuckoo”．Every hour it comes out and says “Cuckoo” the right number of times．It does not get a sore throat at midnight or mid-day!Children find these clocks wonderful．Adults gradually get annoyed because the cuckoo never misses an hour or a half hour,and this makes a short sleep in an armchair rather difficult．
In Europe,the cuckoo's call is a welcome sign that summer is on the way．This is the time when the mother cuckoo flies round,looking for a nest（巢）to lay one of her eggs．She chooses a nest belonging to another bird which already has eggs．When the nest is left unnoticed for a minute or two,the cuckoo rushes down,lays an egg and hurries off．In this way,she may lay her eggs in as many as four different nests．not one of which has been built by herself．
When a cuckoo egg hatches（孵化）,the baby bird is bigger and stronger than the other nestlings．Step by step,it pushes other baby birds and any unhatched eggs out of the nest．In this way,it receives all the food from its foster-parents（养父母）and has a better chance of surviving．

当人们第一次参观瑞士的时候,往往有很大的兴趣,不只是那些山,还有一种出售的叫做布谷鸟钟的钟.当游客购买纪念品的时候,布谷鸟钟很受欢迎,在布谷鸟钟里,每隔半个小时,就有一只小巧的着色的布谷鸟从钟顶出来然后叫“布谷”,每个小时它出来叫“布谷”而且叫得次数等于时间.不论在午夜还是正午,它的喉咙都不会痛.鸡发现这些钟表很好,但是人们却变得生气因为这些布谷鸟从来不会漏报,而这会让躺椅上的一个休息都很难完成.在欧洲,布谷鸟的叫声是受欢迎的信号,预示着夏天的来临.在这个时间段,母布谷鸟会飞来飞去寻找能够放一两个蛋的鸟巢.她会选择属于其他鸟,而且已经有蛋的鸟巢.当这些鸟巢在一段时间内没有被注意到的时候,这些布谷鸟就会冲下来,放下蛋然后匆匆离开.用这种方式,她会放她的蛋最多到4个不同的鸟巢里面,没有一个是她自己建造的.当一个布谷鸟蛋被孵化的时候,幼儿鸟会变得比其他鸟巢里的鸟大而且强健.一步一步的,它会把其他幼儿鸟和没有被孵化的蛋推到鸟巢外面.通过这样,他们就得到了养父母的所有食物,会有更好的生存的机会.
