46) The teaching of English as a second language (ESL) in schools has had a history of conflicting arguments, interesting innovations and some very positive methodological changes. To understand the present situation, it is necessary to consider the past and the wider educational context which has a bearing on it.Until quite recently, approaches to ESL work have been strongly influenced by methods developed to teach English as a foreign language to older learners. These methods placed much emphasis on drills, exercises and remedial programs that focus on language in abstraction. 47) The prescriptive nature of such methods and the demands they made on the teacher’s time developed the belief that ESL work would be tackled only by the specialist ESL teacher working with small groups of children. 48) Such an approach does not fit comfortably into current notions of learning and teaching in the primary school, nor does it sufficientlv equip ESL learners in the secondary school to benefit from normal schooling. In prescribing what language is to be taught, it has ignored what children bring to the learning task and the choices they make about how and what they want to learn. Furthermore, the location and organization of language provision did not measure up to the demand. 49) The language centers and English language services all contributed to providing special and concentrated teaching of English as a second language in small groups, varying in size from four or five to fifteen, Whatever the pattern of provision, the main aim was to give pupils sufficient English to enable them to join normal schools as quickly as possible. The success of such special provision depended very much on the close and constant liaison of language teachers with the subject teachers and the class teachers and on the continuity of learning experiences provided by them. One of the important disadvantages of language centers and withdrawal groups was that ESL children were being taught away from those English-speakers who provide the most powerful models, i.e. their peer (地位相同的) group.Peer group interaction is an important element in any learning situation, but its particular strengths in a classroom with ESL learners cannot be over-emphasized.50) The separation of second-language learners from the main-stream classroom cannot easily be justified on educational grounds, since in practice it leads to both their curriculum and language learning being impoverished.

Online AdsAfter a decade of experimentation, companies have yet to find a reliable way to burnish their brands online. Research shows barely more than 1 in 1000 people click on banner ads. What’s more, they rarely hang around long enough to absorb a brand message. Former Madison Avenue hotshot Matt Freeman aims to change all that. Freeman’s company, Betawave, is developing ways to boost visitor "engagement" and plans to charge advertisers not just by each click or view but also by people’s attentiveness. The concept is untested, but it has generated excitement. Several venture capital shops in December put $ 22.5 million into Betawave. "Matt’s ahead of the curve," says Sean Finnegan, chief digital officer at Starcom Media Vest, which buys ads for Coca-Cola, Procter & Gamble, Nintendo, and others.Mad Ave was shocked when Freeman quit as Tribal DDB Wordwide’s boss in June to run a small company called GoFish. Tribal is widely considered to be one of the most successful creators of online ads anywhere. GoFish, on the other hand, sold ads on a handful of lesser kids’ sites, such as Mini-clip, which hosts online video games, and Cartoon Doll Emporium, where kids play dress-up with avatars. Yes, GoFish, known in the industry as an ad network, had a good reputation among advertisers looking for a cheaper alternative to sites run by Disney and Nickelodeon. But it was in debt, its stock traded over the counter, and it was losing millions a year.Freeman, who has since renamed the company Betawave, says he took the job because he saw unrealized potential. "GoFish was a tiara in the toilet. "he says, noting that the sites Betawave represents share a valuable audience: kids aged 6 to 17 and their rooms. The 25 million people who stop by Betawave sites each month spend an average of 15 minutes per visit vs. nine at Facebook, according to industry tracker Comscore. That "stickiness" has prompted Dellogg, Hasbro, Nintendo, and others to buy ads.Still, Freeman knows companies want more evidence to prove that their ads are working. " Advertisers always say, ’why am I paying for reach when what I want is people’s attention’" That’s why he aims to charge not only for clicks on ads but also for how long people spend on a page and for how much they interact with the brand on a deeper level.To make that happen, Freeman is borrowing from television, which has been shoring up its prospects with "band integrations"—advertisers can veave their products and messages into the shows themselves. In midFebruary, Freeman launched something called Betawave TV. Essentially an online video player, the links of which can be found on many sites, it provides a distribution platform through which clients can integrate their messages into original shows.For the first such experiment, Freeman has enlisted Raven Symone. The Disney twin star will appear in a video and provide style tips that likely will include nods to certain products. Viewers will be directed to WeeWorld, where they will be able to conduct a makeover on a Symone avatar. Freeman plans to charge sponsors a production fee to set up sites like the Symone makeover game. Advertisers also would pay based on the number of people who log in, the number of games played, or a combination of the two.Betawave’s success depends on whether visitors are drawn into the branded games and other content or simply watch what they want and move on. But for now, at least, Freeman has the advertising world’s attention. According to paragraph five, what does Freeman do to carry out his plan（）
