- 英譯漢 An old saying has it that half of all advertising budgets are wasted—the trouble is，no one knows which half. In the Internet age, at least in theory, this fraction can be much reduced. By watching what people search for，click on and say online, companies can aim "behavioural" ads at those most likely to buy. In the past couple of weeks a quarrel has illustrated the value to advertisers of such fine-grained information: Should advertisers assume that people are happy to be tracked and sent behavioural ads? Or should they have explicit permission? In December 2010 America's Federal Trade Commission (FTC) proposed adding a "do not track" (DNT) option to Internet browsers, so that users could tell advertisers that they did not want to be followed. In February the FTC and the Digital Advertising Alliance agreed that the industry would get cracking on responding to DNT requests.

參考答案 常言道：廣告預(yù)算的一半都會被浪費掉——問題是，大家都不知道是哪一半。在網(wǎng)絡(luò)時代，這部分浪費可被大幅減少，至少從理論上講是這樣。商家可以通過觀察用戶搜索的內(nèi)容、點擊的鏈接以及在線的留言，將“行為”廣告有針對性地投送到那些最有可能購買的人群。
在過去的兩周，一場爭論表明了這種精準信息對廣告商的價值：廣告商應(yīng)該假定用戶樂于被追蹤并接受行為廣告，還是應(yīng)先得到用戶的明確許可？
2010年12月，美國聯(lián)邦貿(mào)易委員會提議在互聯(lián)網(wǎng)瀏覽器上添加“禁止追蹤”選項，這樣用戶就可以告知廣告商他們不想被追蹤。今年2月，美國聯(lián)邦貿(mào)易委員會和數(shù)字廣告聯(lián)盟一致同意：該行業(yè)應(yīng)盡快對增設(shè)“禁止追蹤”的要求做出回應(yīng)。

- 9 【英譯漢】 “Sustainability” has become a popular word these days, but to Ted Ning, the concept will always have personal meaning. Having endured a painful period of unsustainability in his own life made it clear to him that sustainability-oriented values must be expressed through everyday action and choice. Ning recalls spending a confusing year in the late 1990s selling insurance. He’d been through the dot-com boom and burst and, desperate for a job, signed on with a Boulder agency. It didn’t go well. “It was a really bad move because that’s not my passion,” says Ning, whose dilemma about the job translated, predictably, into a lack of sales. “I was miserable. I had so much anxiety that I would wake up in the middle of the night and stare at the ceiling. I had no money and needed the job. Everyone said, ‘Just wait, you’ll turn the corner, give it some time.’”
- 10 【英譯漢】 My dream has always been to work somewhere in an area between fashion and publishing. Two years before graduating from secondary school, I took a sewing and design course thinking that I would move on to a fashion design course. However, during that course I realized I was not good enough in this area to compete with other creative personalities in the future, so I decided that it was not the right path for me. Before applying for university I told everyone that I would study journalism, because writing was, and still is one of my favorite activities. But, to be honest, I said it, because I thought that fashion and me together was just a dream ---I knew that no one could imagine me in the fashion industry at all! So I decided to look for some fashion-related courses that included writing. This is when I noticed the course “Fashion Media & Promotion”.
