female will make the final choice. He lands at the hole and turns his head to expose his white cheeks as a signal
to attract the female from where she has been feeding.
Among many birds that nest in holes, the male has a light-coloured patch on its plumage (鸟羽) which acts
as signal for drawing the female's attention to a suitable nesting-place.Unlike the blue tit, the redstart (红尾鸲)
may be only the male that strikingly coloured and the female is not beautiful.
A few years ago I was lucky enough to spot a pair of redstarts in action in a Walsh wood. The male was
leading an interested female to holes that he had previously (先前) checked out. He sat at the entrance of each
hole and put his head on to show off his white forehead, or his head in to reveal (显露) his tail.
If the female failed to react to his visual signals, the male sometimes sang for extra effect, while gliding
towards her on spread wings and tail. Once the female accepts by following the male through the hole the
displays stop, you must be at the right place at the right time to watch them.

C. what the male displayed and won the female

| Advertising is a form of communication that uses all kinds of media, and is visible everywhere these days. Typical customers of advertising companies are other companies, or businessmen, who want to persuade potential customers to buy more of what they make or sell. But there are other kinds of customers. Some organizations spend large sums of money on advertising a political party or other group that sells what is not, strictly speaking, a product or service. Such non - profit organizations are not typical advertising customers, and they prefer ways of spreading knowledge, changing attitudes, and improving society. Many advertisements are designed to increase sales of products and services by either improving brand image or, in the case of non - profit organizations, expressing ideas. In order to achieve th~s, advertisements will often pass on truthful information while delivering their messages. Every major medium is a means of delivering these messages, including television, radio, cinema, magazines, newspapers, video games, the Internet and billboards (大幅广告牌). Advertising will usually be created and. placed by an advertising agency on behalf of company or other organization. Spending on advertising has increased greatly in recent years. In 2006, spending was estimated at $155 billion in the United States and $385 billion worldwide; the latter is expected to reach more than $500 billion by 2010. While advertising can be seen as a necessity for economic growth and social development, it is not without social costs. Advertisement emails and other forms of junk mail have become so popular that ~they have become a major burden to users of I nternet email services, as well as a financial burden on Internet email service providers.
