It swallows its food with its spoon­shaped beak. The performance is for Joel Sartore, founder of Photo Ark, a personal effort to document animals around the world. The critically endangered bird, of which there are fewer than 1，000 individuals in the wild, is the 13，000th species Sartore has photographed in 16 years. His goal is 20，000. 课时作业(二) Before he started Photo Ark, Sartore spent more than a decade working as a photographer for National Geographic, mainly covering conservation stories in the field. He had seen wildlife decreasing firsthand, but felt like the public wasn’t interested. Sartore thought of a new way to inspire people. He picked up his camera and set about taking shots of wildlife—but rather than recording animals in the wild, he wanted to photograph them outside their natural habitat. He visited zoos, aquariums and rehabilitation (康复) centers and photographed portraits of individual animals against a white or black backdrop (背景幕)． 课时作业(二) “This allows you to look them in the eye and see that there’s great beauty there and that they are worth saving，” he said. “We are primates and we respond to eye contact above all else.” The response has indeed been huge. Sartore has more than 1.6 million followers on Instagram and a best­selling series of Photo Ark books. Part of the proceeds (收益) from his books goes to fund on­the­ground conservation efforts. Gary Ward who works at London Zoo where Sartore has shot before, said, “Seeing is the first step to caring, and caring is the first step to conservation action.” 课时作业(二) By choosing animals outside their natural habitat, Sartore admits he will only show a small part of the world's wildlife. According to the International Union for Conservation of Nature, there are more than 2 million described species on the planet, and he plans to photograph just 1% of them. But doing so allows him to spotlight species that are already extinct in the wild, and those that would be difficult to take portraits of in their natural habitat. It also enables him to shoot in a controlled environment, meaning the animal can be kept safe and comfortable, with zookeepers or carers on hand to advise on its behavior. 篇章导读：本文是一篇记叙文。Joel Sartore (乔尔·萨尔托雷)发起了“影像方舟”的计划，即在全球濒危野生动物消失前，留下它们珍贵的影像。他希望以影像的力量唤起公众的关注，助力守护濒危野生动物。 课时作业(二) 1．What is Sartore doing at the beginning of the text? A．He is feeding a bird. B．He is training a bird. C．He is photographing a bird. D．He is studying a bird's behavior. 解析：细节理解题。根据第一段“A spoon­billed sandpiper (勺嘴鹬) ... with its spoon­shaped beak.(一只勺嘴鹬进入镜头，直奔预先放在那里的一只小虫子，并用匙形喙吞咽。)”可知，Sartore在拍摄一只鸟。故选C。 课时作业(二) 2．What does Sartore aim to do with his Photo Ark? A．Make a record of conservation stories. B．Broaden his experience in saving animals. C．Gather information on endangered species. D．Raise people's awareness of protecting wildlife. 解析：推理判断题。根据第四段最后一句“He had seen ... public wasn't interested.(他亲眼看见了野生动物的减少，但觉得公众对此不感兴趣。)”和第五段第一句“Sartore thought of a new way to inspire people.(Sartore思考了一种激励人们的新方式。)”可知，Sartore在拍摄时发现许多野生动物正在减少，但是发现公众并不感兴趣，所以他成立了Photo Ark，由此可推知，其目的是唤起公众对野生动物保护的关注，通过影像激发行动意愿。故选D。 课时作业(二) 3．What is Gary Ward's attitude towards Sartore's work? A．Unclear. B．Approving. C．Doubtful. D．Objective. 解析：推理判断题。根据倒数第二段中的“Seeing is the first step to caring, and caring is the first step to conservation action.(观看是关爱的第一步，关爱是保护行动的第一步。)”可推知，Gary Ward (加里·沃德)对Sartore拍摄动物引起公众关注这种行为持赞成的态度。故选B。 课时作业(二) 4．What is the last paragraph mainly about? A．Why Sartore focuses on animals in human care. B．Why Sartore can't cover all animals in the world. C．The benefits of working with zookeepers or carers. D．The difficulties of photographing animals in the wild. 解析：段落大意题。根据最后一段中的“But doing so allows ... on its behavior.(但这样做可以让他关注那些已经在野外灭绝的物种以及那些在自然栖息地难以拍摄的物种。它还能使他在受控的环境中拍摄，这意味着动物可以保持安全和舒适，动物园管理员或看护人员随时为它的行为提供建议。)”可知，最后一段阐述Sartore聚焦人工圈养动物的原因：便于拍摄濒危物种并确保动物福利。故选A。 课时作业(二) B If you were to throw, say, a banana peel out of your car while driving along the motorway, that would be a completely harmless action, due to the fact that it's part of a fruit, right? Actually, no. A banana peel can take up two years to decompose (分解), and with a third of motorists admitting to littering while driving, that's a whole lot of waste banana peels, or much worse. An orange peel and a cigarette butt have a similar biodegrading (生物降解) term to that of a banana, but tin and aluminum (铝) cans last up to 100 years; and plastic bottles last forever, as do glass bottles and plastic bags. 课时作业(二) Despite the fact that longer­lasting materials will serve to damage the environment, we can't only measure the severity (严重) of a certain type of rubbish by its lifetime. For example, despite having a fairly short biodegrading span, more than 120 tons of cigarette­related litter is thrown in the UK every day. Similarly, our regular littering here and there have caused the UK's mouse population to increase by 60 million. This suddenly isn't so mysterious when you consider that since the 1960s our annual littering has increased by an astonishing 500 percent. 课时作业(二) It's not a cheap habit either: UK taxpayers spent ￡500 million on keeping the streets clean. So, it's not surprising that if caught fly­tipping, you could face a ￡20，000 fine. Regardless of how severe the punishment might seem, however, among the reported cases only 2，000 were punished out of 825，000, so we still have some way to go in making sure people obey the rules. To take back our beautiful cities, we need to do more than simply not leaving rubbish where it ought not to be. We need to care more about the world around us. 篇章导读：本文是一篇说明文。文章介绍了不同垃圾降解的时间及其对环境的危害，以此来号召人们合法扔垃圾。 课时作业(二) 5．Which of the following is the easiest to decompose in the passage? A．A glass bottle. B．A plastic bag. C．An aluminum can. D．An orange peel. 解析：细节理解题。根据第一段可知，橙子皮和香蕉皮相似，需要2年可以分解，铝罐需要100年才可以分解，玻璃瓶、塑料袋和塑料瓶一样，可以永久保存，结合选项可知，橙子皮是最容易分解的。故选D。 课时作业(二) 6．What can we know from Paragraph 2? A．Annual littering has increased a little in the UK since the 1960s. B．Shorter­lasting materials will be less harmful to the environment. C．Cigarette­related littering is a severe environmental problem in the UK. D．Regular littering has caused the UK's mouse population to reach 60 million. 解析：细节理解题。根据第二段中的“For example, despite ... in the UK every day.”可知，在英国，与香烟相关的乱扔垃圾的行为是一个严重的环境问题。故选C。 课时作业(二) 7．Which of the following can best describe the UK's punishment on littering? A．Every little helps. B．More haste, less speed. C．No pain, no gain. D．A drop in the bucket. 解析：推理判断题。根据第三段中的“among the reported cases ... out of 825，000”可知，在报告的82.5万起案件中，只有2，000起受到了处罚，说明处罚的力度不够强。“A drop in the bucket”为英文习语，直译“桶中一滴”，喻指“杯水车薪”或“九牛一毛”，由此可知，此处用来描述其处罚情况恰如其分。故选D。 课时作业(二) 8．What is the best title of the passage? A．Littering, a Surprisingly Big Issue B．Environment Issues, a Big Concern C．Rubbish Collection, an Urgent Task D．Long­lasting Material, a Hidden Danger 解析：标题判断题。通读全文可知，本文主要讲述乱扔垃圾是一个大问题，这种行为造成的影响不容忽视。A项(乱扔垃圾，一个令人惊讶的大问题)最适合作为本文标题。故选A。 课时作业(二) Ⅱ　应用文写作 上周末你参加了校学生会组织的“认识我们身边的植物”活动。请为校英文报写一篇报道，内容包括： 1．活动的过程； 2．收获与感想。 注意：1.写作词数应为80个左右； 2．可以适当增加细节，以使行文连贯。 课时作业(二) Getting to Know the Plants Around Us ﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍ 课时作业(二) [精彩范文] Getting to Know the Plants Around Us Last weekend, I participated in a “Getting to Know the Plants Around Us” activity organised by our Student Union. The activity began with a lecture by a local botanist, who taught us about the different characteristics and uses of various plant species. We then went on a nature walk to observe and collect samples of different plants. Throughout the event, I was struck by the incredible variety of plants that exist in our world and learned about plants that are used for medicinal purposes, as well as those that provide food and shelter for animals. I also gained a greater appreciation for the role that plants play in maintaining the balance of our ecosystem. Overall, it was a valuable and enriching experience. 课时作业(二) 【持续背记】 ①We may be in a culture that gets rid of our worn technology at first sight of something shiny and new. 我们可能处在这样一种文化中，一看到闪亮的新东西，就会摒弃陈旧的技术。 ②It amazed me what random acts of kindness could mean to the people who received it. 让我惊讶的是，不经意的善举对受助者的意义。 ③Lavender is commonly used for relaxation and for falling asleep faster. 薰衣草常用于放松和帮助更快入睡。 课时作业(二) 【持续积累】 at first sight 乍一看；初看之下 random/'rændəm/adj. 任意的，随机的 relaxation/ˌriːlæk'seIʃn/n. 放松；休息 课时作业(二) R $$
