Developers say the apps are educational, and busy parents know that a digital babysitter 1  buy them a few minutes of valuable time. But is the iPad a healthy thing for young kids? ‎ ‎ As  2 (report) by Healthland, the American Academy of Pediatrics (AAP) has advised parents –again- 3 (eliminate) screen time for children under 2, citing concerns about language delays and 4 (disturb) sleep. The academy’s new report drew on studies showing that TV, 5 it’s the parent or the child watching, interferes with “talk time” between parent and child, which is crucial to language development. Does the TV effect apply to iPads too? That’s not clear. “We just don’t have the data yet,” says Dr. Ari Brown, a pediatrician and member of the AAP. Perhaps 6 depends on how you’re using it. Tablets used like a TV should fall under the same guidelines, says Tanya Altmann, a Los Angeles-based pediatrician and author of the best-selling parenting book Mommy Calls.

That is worth 9 (remember) in the wake of last week’s breathless coverage of Apple’s new iBooks platform, 10 the company promises will radically change 11 students use and experience textbooks. Under Apple’s plan, companies and individuals will be able to self-publish textbooks, ideally 12 (create) a wider range of content. Students will be able to download and use these books on their iPad much 13 they would use a regular textbook—including highlighting passages, making notes and pulling out passages or chapters that are especially important to them. Apple says it also plans to cap(限制) the price of textbooks available through iBooks 14 $ 14.99, a significant departure from the price of many textbooks now.‎ Critics were quick to comment that Apple wasn’t being revolutionary enough. Former school superintendent(监管人) and current ed-tech investor Tom Vander Ark 15 (scold) Apple for not thinking past textbooks, which he considers to be hopelessly 20th century. Others worried that Apple’s real goal wasn’t to open up 16 textbook industry but to control it and profit from it through restrictive licensing agreements and a platform that dominates the market. I’m sure that the for-profit company’s shareholders will be horrified at that news.‎ KEYS:9. remembering 10. which 11.how 12. creating 13. as 14. at 15. scolded 16. the C.

People will pay more attention to a humorous commercial than a 2 or serious one, opening themselves up to be 3 . The key to funny advertising is assuring the humor is appropriate to both product and customer. The balance between funny and obnoxious can often be delicate; and a marketer must be certain the positive effects outweigh the negative before an advertisement can be introduced.‎ The best products to sell using humor tend to be those that consumers have to think the least about. Products that are relatively inexpensive, and often 4 , can be represented without providing a lot of facts, and that's where there's room for humor. Candy, food, alcohol, 5 and toys/entertainment related products have proven to benefit 6 from humor in their campaigns. ‎ Another point to consider when using humor in advertising is that different things are funny to different people. A commercial that may leave one person gripping their sides from laughter may leave a 7 in another's mouth. The target 8 must always be considered. What's funny in a client presentation may not be funny on an airplane, at a country club or in a hospital.‎ Humor in advertising tends to improve 9 , but does not improve product recall, message credibility, or 10 . In other words, consumers may be familiar with and have good feelings towards the product, but their purchasing decisions will probably not be 11 . One of the major keys to a successful humorous campaign is 12 , once a commercial starts to wear out there's no 13 it without some variation on the concept. Humorous campaigns are often 14 because they have to be constantly changed. Advertisers must remember that while making the customer laugh, they have to keep things interesting, because old jokes 15 along with their products. ‎ ‎1.
