She had ten children, of whom five survived (幸存). Her husband died in 1937. Grandma Moses is among the most famous twentieth­century painters of the United States, yet she did not start painting until she was in her late seventies. As she once said, “I would never sit back in a rocking chair, waiting for someone to help me.” 课后课时作业（五） 70 Grandma Moses painted a little as a child and made embroidery (刺绣) pictures as a hobby, but only changed to oils in her old age because her hands had become too stiff (僵硬) to sew and she wanted to keep busy and pass the time. Her pictures were first sold at an exhibition, and were soon noticed by a businessman who bought everything she painted. Three of the pictures were shown in the Museum of Modern Art and in 1940 she had her first exhibition in New York. Between the 1930s and her death, she produced some 2，000 pictures, careful and lively pictures of the country life she had known, with a wonderful sense of color and form. 篇章导读：本文是一篇记叙文。文章叙述了Moses (摩西)奶奶的生平简介。她是美国二十世纪最著名的画家之一，但她直到70多岁才开始画画。 课后课时作业（五） 71 解析：推理判断题。根据第一段最后一句“As she once said, ‘I would never sit back in a rocking chair, waiting for someone to help me.’(正如她曾经说过的，‘我永远不会坐在摇椅上，等着别人来帮我。’)”可推知，Moses奶奶很独立。故 选D。 1．From the underlined sentence, we can know that Grandma Moses was ________． A．pretty B．alone C．rich D．independent 课后课时作业（五） 72 解析：推理判断题。根据第三段第一句中的“she wanted to keep busy and pass the time (她想忙起来以此打发时间)”可推知，Moses奶奶开始画画是因为她想保持活力。故选B。 2．According to the passage, Grandma Moses began to paint because she wanted to ________． A．make her home beautiful B．keep active C．improve her salary D．gain an international fame 课后课时作业（五） 73 解析：细节理解题。根据第三段中的“in 1940 she had her first exhibition in New York”可知，1940年，她举办了第一次展览。故选A。 3．When did she have her first exhibition? A．In 1940. B．In 2000. C．In 1937. D．In 1930. 课后课时作业（五） 74 解析：标题判断题。根据第一段第一句“Grandma Moses is among the most famous twentieth­century painters of the United States, yet she did not start painting until she was in her late seventies.(摩西奶奶是美国二十世纪最著名的画家之一，但她直到70多岁才开始画画。)”以及下文对Moses奶奶的生活和作品的介绍可知，文章的最佳标题为“摩西奶奶”。故选A。 4．Which of the following can be the best title for the passage? A．Grandma Moses B．Grandma Moses and Children C．Grandma Moses: Her First Picture D．Grandma Moses and Her First Exhibition 课后课时作业（五） 75 B About 97% of the world's water is salty and is found in our oceans and seas. But, as we can't drink sea water, how can it be important? Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important sea water is! 课后课时作业（五） 76 Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains are delicately (微妙地) balanced. The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn't matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop. 课后课时作业（五） 77 Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most countries have introduced fishing restrictions to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important sea water is！ 篇章导读：本文是一篇说明文。文章主要讲了海水对人类的重要性及人们采取的一些保护海洋的措施。 课后课时作业（五） 78 解析：细节理解题。根据倒数第二段中的“People once thought that the oceans were so big ... and fish stocks in the oceans have started to drop. (人们曾经认为海洋是如此之大，我们是否向海洋倾倒垃圾或捕获大量的鱼和鲸鱼作为食物都无关紧要。但我们现在知道并非如此，海洋中的鱼类资源已经开始减少。)”可知，人类的过度捕捞使鱼类资源减少。故选C。 5．From the passage, we learn that ________． A．most fish and sea animals live at the surface of the seas B．it is very difficult to break the balance of a food chain C．over­fishing has caused the decrease in fish stock D．it won't be long before the problems concerning oceans will be solved 课后课时作业（五） 79 解析：词义猜测题。画线短语所在的句子表示大多数国家都采取了捕鱼限制措施，以保护海洋中的鱼类资源，并正在开创处理污染的新技术。由此可知，cope with意为“处理”。故选A。 6．What does the underlined phrase “cope with” mean in Chinese? A．处理 B．保护 C．增加 D．检验 课后课时作业（五） 80 7．Which of the following can't be concluded from the passage? A．The use of international agreements. B．Forbidding fishing to protect fish stocks. C．The use of new techniques. D．Raising people's awareness of the need to protect oceans. 课后课时作业（五） 81 解析：推理判断题。根据最后一段第一句中的“introducing international agreements to protect marine habitats”和第二句中的“new techniques are being pioneered to cope with pollution”以及第三句中的“the importance of protecting oceans is being made known to more people”可推知，A、C、D三项都是保护海洋的方法。B项(为了保护鱼类资源而禁止捕鱼)，与最后一段第二句中的“Most countries have introduced fishing restrictions to protect fish stocks in the oceans (大多数国家实行了捕鱼限制，以保护海洋中的鱼类资源)”表达不一致。故选B。 课后课时作业（五） 82 解析：标题判断题。通读全文可知，第二段和最后一段的最后一句都提到“How important sea water is！”由此判断，文章反复强调海水是多么重要。所以A项(海水的重要性)最适合作为文章标题。故选A。 8．What would be the best title of the passage? A．The Importance of Sea Water B．Life in the Oceans C．How to Protect Food Chains D．How to Deal with Sea Water Pollution 课后课时作业（五） 83 Ⅲ　七选五 Urban Wildlife Cities are diverse ecosystems. In addition to visitors from the wild, a large number of species share our urban areas. As our cities spread, we need to think about what it is like for other species to have human neighbors.Cities are built for humans. __1__ For example, most city parks are kept neat and tidy so that humans will find them beautiful. But when we cut grass or plant flowers, we destroy natural habitats. __2__ When a bridge in Austin, Texas was repaired, engineers added small gaps running along the length of its bottom. This made a good home for bats, and soon the bridge was the home of thousands of bats. __3__ Now, they have come to value their winged neighbors. The bats are a tourist attraction, and they eat lots of bugs every night. 课后课时作业（五） 84 There are also structures built with the aim of bringing wildlife into the city. The Beijing Olympic Forest Park is a good example. The park used native plants and created open, natural spaces for wildlife. The result is a zone in Beijing with over 160 species of birds. In many ways, the park is the opposite of a zoo. __4__ If we learn to share our space, we can become better neighbors to the wildlife around us. __5__ Our own future will be endangered too. A．They are built to protect birds. B．Our actions sometimes help other species.
