【解析】

这是一篇说明文。文章主要介绍了在过去的70年里,中国在环境保护方面取得了很大的进步。保护野生动物无疑是重要的一环节。

【1】根据前文China has made great improvements in environmental protection during the past 70 years.可知,在过去的70年里,中国在环境保护方面取得了很大的进步。再根据后文Each species (物种)on Earth has a role to play in the ecosystem.可知,地球上的每一个物种都在生态系统中扮演着重要的角色。由此可知,G项Protecting wildlife is, without doubt, an important part.(保护野生动物无疑是重要的一环节)切题。故选G。

【2】根据前文In recent decades, a series of wildlife-protection movements have been carried out by the central government.可知,近几十年来,中央政府开展了一系列的野生动物保护运动。由此可知,E项Several species in danger of extinction have made impressive progress thanks to the methods.(一些濒临灭绝的物种由于采取了这些保护措施而取得了令人瞩目的进展)切题。故选E。

【3】根据后文By the end of last year, seven of the nine pandas released had survived in the wild.可知到去年年底,放归的9只大熊猫中有7只在野外存活。由此可知,C项Scientists have worked to feed pandas and then release them into the wild.(科学家们一直致力于喂养大熊猫,然后将它们放归野外)切题。故选C。

【4】根据后文In 1981 , only seven crested ibises were found in Yangxian county, Shaanxi Province…China has even sent crested ibises to Japan and South Korea in recent years, to help with the species' survival.可知,在1981,在陕西省的洋县,只发现七只凤头鹦鹉.近年来,中国甚至将朱鹮送往日本和韩国,以帮助该物种的生存。由此可知,B项Another species was once thought to be extinct.(另一个物种曾经被认为已经灭绝)切题。故选B。

【5】根据后文Key projects will be continually carried out to improve protection, including making the lists of wild animals and plants under State protection, and also fighting against illegal wildlife trade, which includes ivory(象牙).可知,继续实施重点保护工程,包括制定国家保护野生动植物名录,打击包括象牙在内的非法野生动物贸易。由此可知,F项China will continue its efforts of the wildlife protection.(中国将继续加强野生动物保护)切题。故选F。

【题目】Next time you’re planning to go out for a relaxing walk with your MP3 player, be sure to check the weather forecast first. Summer is the prime time for lightning strikes, a fact that Jason Bunch, a teen from Castle Rock, Colo, learned in a hard way. A couple of summers ago, he was mowing (割草) grass while listening to some Metallica on his iPod. Although there wasn’t any rain falling on Bunch, he did hear distant thunder. Bunch was then struck by lightning, which seemed to travel through his music player, blowing out his eardrums and leaving him with burns where the device and its power lines were close to his body.

Devices such as MP3 players don’t attract lightning, says Dr. Mary Ann Cooper, an emergency room physician at the University of Illinois Medical Center in Chicago. However, they may change the pathway that lightning’s energy follows in the human body. Lightning that might have passed rather harmlessly over the skin may react differently to the metal of these devices and cause damage.

Rather than leaving your tunes at home, your best bet is watching out for lightning before it hits. Though people have been injured while using MP3 players in storms, Cooper says, “The devices’ main task is keeping you from paying attention to thunder and the sky.” If you’re caught in a storm, seek shelter.
