Ⅰ.阅读理解 A Earth Day falls on April 22 each year to inform people about environmental problems and inspire them to act.It first came into being in 1970，followed in 1972 by World Environment Day.It has been celebrated ever since，slowly but surely picking up steam.Interestingly，it remained a grassroots affair for 20 years before spreading out to 140 countries in 1990.Now，it is celebrated around the world.Humans still face many challenges，such as climate change and plastic pollution.But we can all make a difference. When Claire was in the seventh grade，she learned about plans to expand and modernize her middle school.As a follower of Earth Day and conservationist，she wanted to help.Claire asked the school board to add solar panels to the project because，she explained，clean energy would contribute to a truly modern school，and help her school pursue sustainable development. The board was in favour of the idea but said it could contribute just $25，000，one-fifth of the cost.So Claire turned to the community，looking for a solution.Her friends and neighbors shared her enthusiasm.Soon Claire organized a group of kids and adults，who set to work raising the rest.They wrote grant (拨款) requests，put on a talent show and asked for donations，even going door-to-door for them at Halloween.And they appealed to charitable foundations too.One donated more than half the cost! After two years of hard work，the group paid for the solar panels，which now supply one-fourth of the school's electricity needs，saving the district thousands of dollars.“My favorite part about this project was that one person could start something small and then the project could grow and have a big impact on the community，” Claire said.“There are always going to be barriers and hard parts.When there's a challenge presented to you，use it as a learning moment and overcome it.” You can be a hero for the environment，so find out what can be recycled where you live.

As newer，more advanced devices come out，huge amounts of old electronics are thrown away，instead of being recycled.These items often end up in landfills，where the chemicals inside them may be a danger to the environment.Electronics can contain noxious materials like lead or mercury (汞).If these materials get into the ground or water，the pollution can cause serious problems. Most electronics require rare metals.These metals must be mined (开采) from the earth.Often the mining process creates serious pollution.In many cases，these metals are getting harder and harder to find.If more e-waste was recycled，many of those rare metals could be taken from old electronic devices instead of being mined.A group known as the WEEE (Waste Electrical and Electronic Equipment) Forum is trying to make people more aware of the problems of e-waste.The WEEE Forum says that the rare metals and other materials that get thrown out as e-waste every year are worth about $57 billion. Recently，The WEEE Forum asked researchers from the United Nations to study a kind of e-waste that's often not noticed because people don't consider the items to be electronics.The WEEE Forum calls this type “invisible” e-waste. The surprising type leading the invisible e-waste group was toys.Worldwide，about 7.3 billion electronic toys are thrown away each year.In all，toys make up about 35% of invisible e-waste.But the problem is far larger than just toys.The report also shows that other everyday items like alarms，power tools，and computer cables (电缆) are also massive sources of invisible e-waste.The UN report says that 36% of the world's invisible e-waste comes from these three types. The WEEE Forum is hoping that as more people and governments become aware of e-waste，they will make a much greater effort to make sure electronics get reused or recycled. [语篇解读]　本文是一篇说明文。文章主要介绍了电子垃圾的危害和隐形电子垃圾的分类，呼吁人们对电子垃圾进行再利用和回收，从而减少电子垃圾对环境产生的危害。 5．What does the underlined word “noxious” mean in paragraph 2? A．Harmful. B．Critical. C．Powerful. D．Abnormal. 解析　词义猜测题。根据画线词后文“If these materials get into the ground or water，the pollution can cause serious problems.”可知，此处指电子产品中含有像铅或者汞这样的有毒材料，一旦这些材料进入到土地里或者水里，就会造成严重的污染问题。故画线词意为“有毒的；有害的”，与harmful同义。故选A。 答案　A 6．How can we reduce the impact of rare metal mining on the environment? A．Looking for alternative options. B．Recycling rare metals from e-waste. C．Buying rare metals from other countries. D．Reducing the production of electronic devices. 解析　推理判断题。根据第三段中的“If more e-waste was recycled，many of those rare metals could be taken from old electronic devices instead of being mined.”可推知，可以从电子垃圾中回收稀有金属来减少稀有金属开采对环境的影响。故选B。 答案　B 7．Which items account for the highest percentage of invisible e-waste? A．Toys. B．Alarms. C．Power tools. D．Computer cables. 解析　细节理解题。根据第五段中的“The surprising type leading the invisible e-waste group was toys.”可知，玩具是隐形电子垃圾中占比最大的一类产品。故选A。 答案　A 8．What is the WEEE Forum's hope for the future of e-waste? A．That e-waste will soon no longer be a problem. B．A global law on electronic devices will be issued. C．E-waste will be burned to avoid damage to the environment. D．Everyone will play a part in reusing and recycling electronics. 解析　细节理解题。根据最后一段“The WEEE Forum is hoping that as more people and governments become aware of e-waste，they will make a much greater effort to make sure electronics get reused or recycled.” 可知，WEEE论坛希望每个人都会在电子产品的再利用和回收中发挥作用。故选D。 答案　D Ⅱ.完形填空 I went with some colleagues for dinner in a very popular local restaurant.It was 1 business time and the restaurant was crowded.
