Wildlife Protection李仕才***阅读理解。

We know a lot about the advantages and disadvantages of reading a hard­copy book vs. reading electronically. The problem is, many of us refuse to listen.Do n’t get me wrong: Digital reading has some real advantages. Ask peo ple what they like most about reading on digital screens, and you hear over and over again about convenience. More points for digital reading：e­books tend to be cheaper. There’s also the environmental argument. Think of the trees!Yet the soundness of this case is arguable. The earth metals to build e­readers are not just rare but highly poisonous. And think about all that energy needed to run servers and cooling fans. And remember, trees are a renewable resource.Then, there’s the appeal of a hard copy. Many people prefer print when reading both for pleasure and for school or work. Drawing examples from my own research, some of the reasons are aesthetic(美学的). Others involve a sense of accomplishment, ease of annotation(“I can write on the pages”), and navigation(“easy to locate where I was”). Meanwhile, I hear abundant complaints about eye strain(眼疲劳) and headaches when using screens.Much of what students liked about reading print involved their minds. They say “it’s easier to focus”. Some also acknowledged they took more time with printed text and read more carefully.But what makes the failure of electronic reading is concentration. More than 92% of those I surveyed said they concentrated best when reading a hard copy. When a digital device has an Internet connection, it’s hard to resist the temptation(诱惑)．So if digital interruptions don’t threaten your enjoyment or understanding of a text, then medium may not matter. Casual reading like David Baldacci? If you break to check sports scores, there will be little harm done. But just don’t expect to understand Joyce’s novels this way.【解题导语】文章主要介绍了在网络高度发达的社会中，电子书愈来愈有替代纸质书的趋势，然而作者通过对比两者的优缺点表达了对纸质书的青睐。

Reading课文学习HOW DAISY LEARNED TO HELP WILDLIFE黛西如何学会帮助野生动物Daisy had always longed to help endangered species of wildlife. One day she woke up and found a flying carpet by her bed. "Where do you want to go?" it asked. Daisy responded immediately. "I'd like to see some endangered wildlife," she said. "Please take me to a distant land where I can find the animal that gave fur to make this sweater." At once the carpet flew away and took her to Tibet. There Daisy saw an antelope looking sad. It said, "We're being killed for the wool beneath our stomachs. Our fur is being used to make sweaters for people like you. As a result, we are now an endangered species." At that Daisy cried, "I'm sorry I didn't know that.I wonder what is being done to help you. Flying carpet, please show me a place where there's some wildlife protection."黛西一直渴望帮助濒危野生动物物种。
