It made us very sad to see how plastic harms wildlife and pollutes the ocean, and we want to change this，” reads the petition. “That's why we want Burger King and McDonald's to think of the environment and stop giving away plastic toys with their kids meals.” 课时作业(四) 9 “We like to go to eat at Burger King and McDonald's, but children only play with the plastic toys for a few minutes before they get thrown away and harm animals and pollute the sea. We want anything they give us to be environmentally friendly so we can protect the planet for ourselves and for future generations，” they continued. In addition to the girls making a convincing argument, the amount of signatures on the petition almost doubled after reporters with the BBC's War on Plastic followed the young activists to the McDonald's headquarters in order to present the petition. 课时作业(四) 10 Since the little girls' story started being picked up by international news outlets, Burger King and McDonald's have emailed statements to CNBC detailing their plans for making their free toys more environmentally friendly. 篇章导读：本文是一篇新闻报道。英国两名小女孩通过网络将成千上万的人聚集在一起，签署请愿书，希望汉堡王和麦当劳考虑环境问题，停止给孩子们分发塑料玩具。 课时作业(四) 11 1．Why are the two little girls gathering many people together?

The mountains stand across the border between Gansu and Qinghai Provinces. The nature reserve became a national protected site in 1988, but hundreds of mines in the area and various construction projects took__a__toll on the environment. 课时作业(四) 16 Thanks to the recovery of the mountains' environment and greater efforts to protect wildlife, many protected and rare wild animals have been sighted very often in recent years. The city has also moved away all farmers, herdsmen and one－third of its people who were living in the mountains to a new zone and helped them find jobs in an effort to reduce the pressure on the environment. Scientific research and advanced technology are key to the restoration (重建) of the mountains' ecology (生态), said Wang Tao, a researcher at the Chinese Academy of Sciences, Northwest Institute of Eco－Environment and Resources. 课时作业(四) 17 Wang said a research center led by the institute was set up last year to focus on ecosystem recovery and the ecological management of the mountains under the influence of global climate change. The center has begun research to carry out environmental observation and assessment (评估), providing support for the creation of a Qilian Mountains national park, he added. To better protect the mountains, Wang said, it's necessary to promote large－scale, rapid observation approach and build a great ecological assessment system in the reserve. 课时作业(四) 18 A data－sharing (数据共享) management system should be pushed forward to create a database (数据库) of the mountains, environment, which would support its protection in a scientific way, he added. 篇章导读：本文是一篇说明文。文章介绍了祁连山国家自然保护区的现状和未来需要采取的环保措施。 课时作业(四) 19 5．What does the underlined phrase “took a toll” in the second paragraph mean?
