{{B}}Part Ⅱ Vocabulary{{/B}}
There are four passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.
Passage one: Questions 21-25 are based on the following passage.

This year the combined advertising revenues of Google and Yahoo ! will rival the combined primetime ad revenues of America's three big television networks, ABC,CBS and NBC predicts Advertising Age. It will, says the trade magazine, represent a "watershed moment" in the evolution of the internet as an advertising medium. A 30-second prime-time TV ad was once considered the most effective--and the most expensive--form of advertising. But that was before the internet got going. And this week online advertising made another leap forward.
This latest innovation comes from Google, which has begun testing a new auction-based service for display advertising. Both Google and Yahoo! make most of their money from advertising. Auctioning keyword search-terms,which deliver sponsored links to advertisers' websites, has proved to be particularly lucrative. And advertisers like paid-search because, unlike TV, they only pay for results: they are charged when someone clicks on one of their links.
Both Google and Yahoo! along with search-site rivals like Microsoft's MSN and Ask Jeeves, are developing much broader ranges of marketing services. Google, for instance, already provides a service called AdSense. It works rather like an advertising agency, automatically placing sponsored links and other ads on third-party websites. Google then splits the revenue with the owners of those websites, who can range from multinationals to individuals publishing blogs, as online journals are known.
Google's new service extends AdSense in three ways. Instead of Google's software analyzing third-party websites to determine from their content what relevant ads to place on them, advertisement will instead be able to select the specific sites where they want their ads to appear. This provides both more flexibility and control, says Patrick Keane, Google's head of sales strategy.
The second change involves pricing. Potential internet advertisers must bid for their ad to appear on a "cost-per-thousand" (known as CPM) basis. This is similar to TV commercials, where advertisers pay according to the number of people who are supposed to see the ad. But the Google system delivers a twist: CPM bids will also have to compete against rival bids for the same ad space from those wanting to pay on a "costper-click" basis, the way search terms are presently, sold. Click-through marketing tends to be aimed at people who already know they want to buy something and are searching for product and price information, whereas display advertising is more often used to persuade people to buy things in the first instance.
The third change is that Google will now offer animated ads--but nothing too flashy or annoying, insists Mr. Keane. Such ads are likely to be more appealing to some the big-brand advertisers. Spurred on by the spread of faster broadband connections, such companies are becoming increasingly interested in so-called "rich-media" ads. like animation and video.

单选题 By saying "It will represent a 'watershed moment' in the evolution of the internet as an advertising medium" ,the trade magazine suggests ______

【正确答案】 B

【答案解析】[解析] 本题问：商业杂志说“It will represent a‘watershed moment’in the evolution of the internet as an advertising medium”意指什么。相关部分在文中第一段开头，提到广告时代预测本年度谷歌和雅虎两大网络公司的广告收入将可以和美国三大电视网在黄金时段的广告总收入相抗衡，称这是因特网作为广告媒介这一发展过程中的一个“watershed moment”。本题理解的关键是“watershed moment”，根据上下文可以判断网络广告已经对电视广告构成威胁，并已取得显著成绩。因此，网络广告的出现为因特网成为广告媒介提供了契机。故B“谷歌和雅虎的成功成为网络广告发展的转折点”为正确项。

单选题 Now, the most effective form of advertising is ______

单选题 Why do advertisers like the new auction-based service for display advertising?

单选题 Which of the following is not included in Google's new service which extends AdSense?

【正确答案】 D

【答案解析】[解析] 本题问“哪一项不是谷歌扩展了AdSense的服务”。题文相关部分在短文第四、五、六段，文中提到“Google's new service extends AdSense in three ways…advertisement will instead be able to select the specific sites where they want their ads to appear…The second change involves pricing…The third change is that Google will now offer animated ads．”(谷歌通过三种方法使AdSense服务得以扩展……广告可以根据广告商的喜好可以被刊登在看好的网站上……第二种方法是对价格的调整……第三种方法是谷歌公司在广告中加入了动画的元素)。A“广告可以根据广告商的喜好被选择出现在不同的网站上”是文中提到的第一种方法。B“广告客户根据浏览广告的人数付费”是文中提到的第二种方法。C“广告商提供动画广告”是第三种方法。文中提到谷歌并不是通过分析第三方的网站内容来决定其网站上应该放置何种相关广告，因此谈不到就广告内容给广告商提出建议。因此，D“广告商得到关于广告内容的建议”不是谷歌提供的的服务。
