The lights had gone out, the oven stopped working and my phone was no longer charging. I attempted to fix electricity, but I soon realized that I couldn't. I had to wait for an electrician to come in the morning. After messaging my friends to say that I wouldn't message tonight because I couldn't charge my phone, I sat down to eat my half­cooked dinner. Then I wasn't sure what to do. My typical evening is spent watching TV and browsing social media. So__for__me,__tonight__was__an__early__night. 课时作业(二) 15 I couldn't help but think whether we rely too much on electricity. Losing our electricity felt like losing a basic necessity as running water. In fact, electricity is a luxury that we have grown to take for granted. I use electricity all the time, even when it's not really necessary. I use it to put the TV on in the background even when I'm not really watching it. I use it to check my phone when I wait for my friends even just a minute. Our over­use of electricity is a big problem. It contributes to global warming, which is what we should be worried about. What we need to do is stop it. If we continue to use the same large amount of energy, we will soon run out. 课时作业(二) 16 How would we survive in a world without electricity? So, shouldn't we start preparing for it now? Cutting back on our use of electricity saves energy resources so that they could last for longer. I know that I could cut down on my use of electricity. And if everyone does the same, we can make a difference. 篇章导读：本文是一篇夹叙夹议文。作者通过自己的经历告诫大家：节约能源，从我做起。 课时作业(二) 17 1．What did the author do when electricity went out suddenly?

Most scientists agree that efforts are necessary to protect our environment from further harm. As we know, the construction industry consumes a large quantity of energy and resources and creates a huge amount of pollution. So green buildings are in great need. 课时作业(二) 22 The environmental benefits of building green include the protection of ecosystems and biodiversity (生物多样性), improved air and water quality, less waste flowing into streams and the protection of natural resources. Green buildings can also result in lower operating costs because they typically use less energy and fewer materials and improve indoor air quality, improving the health of people who live there. The process of building green includes technical and artistic planning with nature protection in mind. Building designs often reflect the surrounding environment and natural resources and use renewable building materials such as bamboo and straw. In addition, recycled resources found locally are used for green buildings, reducing the cost and air pollution associated with transporting materials long distances. 课时作业(二) 23 Careful site selection is important to minimize (最小化) human effect on the surrounding environment. For example, placing a structure in an area that allows it to take advantage of cool breezes (微风) and sunlight can reduce energy use and expenses. More energy and expense are needed for larger buildings as well, so it is important to build small. Green roofs are another feature of green houses that reduce energy use and cost. These roofs are partially or completely covered with plants, which helps to keep heating and cooling costs low, prevent water running off and deal with pollutants. 课时作业(二) 24 Other features of green buildings often include energy and water protection, recycling and waste reduction. In addition, renewable energy sources such as solar power, water power and wind power are used for heat and electricity, which greatly reduces costs and decreases the influence on the environment. 篇章导读：本文是一篇说明文。文章介绍了绿色建筑的诸多优点，它们能够更加有效的改善空气和水的质量，减少废物流入河流，从而使自然资源得到保护。 课时作业(二) 25 5．Which advantage is not included about the building green? A．To upgrade the quality of air and water. B．To reduce the waste flowing into streams. C．To protect the ecosystems and biodiversity. D．To enhance our human being's life quality. 解析：细节理解题。根据第二段第一句可知，建造绿色建筑的环境效益包括保护生态系统和生物多样性，改善空气和水质，减少流入河流的废物以及保护自然资源。D项(提高人类的生活质量。)未提及。故选D。 课时作业(二) 26 6．What is a green building probably like according to Paragraph 4? A．Small. B．Large. C．Warm. D．Cool. 解析：推理判断题。根据第四段最后一句“More energy and expense are needed for larger buildings as well, so it is important to build small.”可知，大型建筑物也需要更多的能源和费用，因此建造小型建筑物很重要。由此可推知，绿色建筑最有可能是小型建筑。故选A。 课时作业(二) 27 7．Why do we choose to use green roofs? A．To fit the environment. B．To lower expenses. C．To collect nature water. D．To keep warm or cool. 解析：细节理解题。根据第五段第一句“Green roofs are another feature of green houses that reduce energy use and cost.”可知，屋顶绿化可以减少能源消耗和成本。选择使用绿色屋顶是为了降低开支。故选B。 课时作业(二) 28 8．What is the text mainly about? A．Environmental benefits. B．Building green. C．Promoting energy efficiency. D．Ecosystems and biodiversity. 解析：主旨大意题。文章主要讲述了绿色建筑的各种特点，其能够有效地改善空气和水的质量，减少废物流入河流，进而使自然资源得到保护。结合第一段最后一句“So green buildings are in great need.” 可知，绿色建筑是非常需要的。B项(建造绿色建筑。)符合文章主旨。故选B。 课时作业(二) 29 Ⅲ　语法填空 Chopsticks, or kuaizi in Chinese, __1__ (be) a pair of small equal­length sticks, usually made of wood, __2__ (use) for eating Asian food.

He wanted to cut a path through unexplored lands and discover rare species. That might sound like an impossible dream, but Bexler turned it into a reality. In December 2015, he and a team of Australian scientists explored an isolated rainforest on the island of New Guinea.They were the first people to enter the region. “As time was limited, we were dropped in by helicopter. Once we were on the ground, there were no trails anywhere; it was really hard to get around，” Bexler says. 课时作业（三） 44 Within minutes of landing, the team spotted a black chicken­like bird with strange orange skin hanging from its neck. The scientists soon determined that the unusual creature was a type of honeyeater—the first new bird species to be sighted on New Guinea in 60 years. The honeyeater wasn't the only surprise for the scientists. They discovered more than 40 previously unknown plant and animal species—13 birds of paradise, 20 frogs, four butterflies, and five palms. “We were like kids in a candy store，” Bexler recalls. “Everywhere we looked, we saw amazing things we had never seen before.” 课时作业（三） 45 The newfound species didn't shy away from the scientists. Two long­nosed echidnas—primitive egg­laying mammals—let the visitors pick them up and take them back to camp to study them. Bexler thinks the animals weren't frightened because they had never seen humans before. “In almost all parts of New Guinea, animals are hunted for food, and because of this, they are very cautious of people，” he explains. “This area gives scientists a place where they can go to study the behaviors of animals that have not yet learned to be afraid of people.” 课时作业（三） 46 Scientists believe the area is probably the largest untouched forest in Asia.Bexler and his team did not have enough time to study the area completely. They hope to return to record more undiscovered species. “We just scratched the surface，” Bexler says. “Anyone who goes there will come back with a mystery.” 篇章导读：本文是一篇记叙文。 文章讲述了Bruce(布鲁斯)和一支澳大利亚的科学团队探索了一座人迹罕至的岛屿，在那里发现了许多从未见过的生物。 课时作业（三） 47 1．Which word best describes Bruce Bexler? A．Modest. B．Adventurous. C．Optimistic. D．Confident. 解析：推理判断题。根据第一段“For many years, Bruce Bexler dreamed of going where no human had gone before. He wanted to cut a path through unexplored lands and discover rare species.”可知，他一直梦想着去人类没有去过的地方，探索一些未知的地方，由此判断出他是一个喜欢冒险的人。 故选B。 课时作业（三） 48 2．What does Bruce Bexler mean in Paragraph 5 when he says the scientists “were like kids in a candy store”？ A．They didn't have enough food and were hungry. B．They were very excited about what they saw. C．They were behaving like naughty children. D．They knew that if they kept searching, they'd find sugar. 解析：推理判断题。根据第五段最后一句“Everywhere we looked, we saw amazing things we had never seen before.”可知，环顾四周他们所看到的都是从未见过的神奇事物，用“像孩子在糖果店一样”来表达科学家们面对新发现时的兴奋、激动之情。 故选B。 课时作业（三） 49 3．Why did some of the animals allow the scientists to pick them up? A．The scientists seemed to be very friendly. B．The scientists were good at handling animals. C．The animals had been well­trained by the local people. D．The animals had no experience or fear of people. 解析：细节理解题。根据第七段第一句“Bexler thinks the animals weren't frightened because they had never seen humans before.”可知，这些动物们不惧怕人类是因为它们根本没见过人类。所以这些动物允许人类把它们带回去是因为这些动物没有接触过人类，不怕人类。故选D。 课时作业（三） 50 4．What can we conclude about the area Bruce Bexler explored? A．The best way to explore the area is by helicopter. B．The area has not been visited by scientists for many years. C．The area still contains many plants and animals unknown to science. D．The locals are unwilling to allow the scientists to enter the deep woods. 解析：推理判断题。根据最后一段中的“They hope to return to record more undiscovered species.”和“We just scratched the surface”可知，本文中的科学团队在无人岛屿上发现的物种还只是冰山一角，仍然有许多动植物是未知的。由此判断出，这个地区仍然有许多科学上未知的动植物。故选C。 课时作业（三） 51 Ⅱ　语法填空 Nobody __1__ (like) to lose, but we must accept that losing is part of life. After all, we can't win all the time. Although losing is __2__ (please), it can be a positive thing. We can learn from every failure, which may help us succeed in the future.

However, in recent years, the new energy cars has gained its popularity in particular. Compared with traditional cars, the new energy car plays an important role in saving energy, which will not only help solve the shortage of energy but also help reduce the expenses used for fuel. What's more, with clean energy, air pollution will be reduced a lot, for which we will have more fresh air to breathe in. In addition, the pace of global warming caused by greenhouse will be slowed down as well. 课时作业（三） 61 As far as I'm concerned, although it will be a long time before this new invention is perfected, the traditional cars will be replaced sooner or later for its shortcomings.
