A．gave out; helped B．gave away; to help C．put out; to help D．gave in; helped 【答案】B 【详解】句意：汤姆捐出许多钱给有困难的人来帮助他们。 考查动词短语辨析及动词不定式。gave out分发；gave away捐赠；put out扑灭；gave in屈服。根据“lots of money to the people in trouble”可知，这里应该是把钱捐赠给那些需要的人，因此第一个空用动词短语gave away；第二个空是动词不定式作目的状语。故选B。 5．Writing has helped me to ________ myself.

They don’t need a heart to pump blood because they don’t have any. And they have a nerve net—which is sensitive to touch—below their outer skin. They respond to the changes in their environment using signals from the nerve net, so they don’t need a … to process complex thoughts.”可知，由于水母自身生长的特征，它们的皮肤可以呼吸，它们没有血液所以没有心脏，它们有神经网可以感知外面的环境。因此这里表达的是“一切的安排都是最好的”。故选D。 14．句意：它们没有肺是因为它们的皮肤是如此之薄以至于能通过皮肤吸收氧气。 so如此；too也，太；such如此（后面加冠词+名词）；very很，非常。根据语境，这里考查so+形容词+that从句表示“如此……以至于……”。故选A。 15．句意：它们用神经网信号来反射环境变化，因此它们不需要大脑加工复杂的想法。 lung肺；brain大脑；heart心脏；tentacle触角。根据“Surprisingly, they don’t have a brain, a heart, or lungs（肺）”可知，水母是没有大脑，心脏和肺的，前面已经介绍为什么没有肺和心脏。这里是介绍没有大脑是怎么感知外界的。故选B。 16．句意：然而，触角永不缠绕在一起或刺到自己。 But但是；Anyway不管怎样；However然而；Otherwise否则。根据前文“Some jellyfish have very long tentacles”可知，一些水母有很长触角，“但是”触角是不会缠绕在一起或者刺到他们自己，这里表示转折，横线后有逗号。故选C。 17．句意：大部分水母几乎没有或者就是没有视力，但它们可以察觉到光和洋流，这能帮助它们行进和移动。 good好的；much许多；little少，几乎没有；a little一点点。根据后面的“… or no vision, but they can detect light and ocean currents,”可知，它们不是通过视力感知光和洋流的。因此视力是“几乎没有”。故选C。 18．句意：水母大小不一，从0.5毫米到直径2米多，体重重达200公斤多的巨型越前水母。 types类型；sizes尺寸，大小；looks面貌；colours颜色。根据后文“from 0.5 millimeters to the giant Nomura’s jellyfish, which can measure up to two meters in diameter and weigh over 200 kilograms.”可知，这里说的是水母的“大小”。故选B。 19．句意：尽管水母很漂亮，但是它们也很危险。 pleasant令人愉快的；dangerous危险的；surprising令人惊讶的；interesting有趣的。根据文“Some jellyfish toxins can be deadly to humans”可知，水母有毒且对人类是致命的。所以水母应该是“危险的”。故选B。 20．句意：在任何情况下，最好要远离任何你看到的水母。 in the way阻挡，妨碍；on the way在路上；away远离，后加from；out of the way远离。 根据前文“Some jellyfish toxins can be deadly to humans, such as those from the box jellyfish and …”可知，水母毒素对人类是致命的，因此要“远离”它们。故选D。 三、阅读单选 A The great white shark（鲨鱼）is one of the most dangerous animals in the world. It can grow up to 7 meters long and weigh 2,100 kg. It has five rows of up to 3,000 very white, very sharp teeth. It needs them because the great white shark is a carnivore. It will eat almost anything that swims in the sea, from fish to dolphins to other sharks. Oh, and people, too. So, imagine how Rob Howes felt when he faced one of these terrifying animals off the northern coast of New Zealand. Rob was swimming with his 15-year-old daughter, Niccy and two of her friends. They were enjoying the crystal-clear water when they noticed some dolphins（海豚）swimming up to them. It is not surprising to see dolphins in the waters there, and they often swim near humans. But these dolphins were not there for fun. They were swimming around the four humans in smaller and smaller circles. It seemed like they were gathering up the swimmers. Also, the dolphins were hitting their tails on the water. Were they trying to tell them something? That was when Rob saw the great white shark. It was very close—only a few meters away. It wasn’t a big one, but at 3 meters long, it was big enough. It was swimming towards them, gliding through the water, but when it saw the dolphins, it turned and swam away. Rob realized that the dolphins had saved their lives. Had they known there was a shark nearby and decided to protect them? The dolphins followed the swimmers until they got safely back to shore（岸）. Rob and the others were very lucky that day. Some people pay lots of money to swim with dolphins. Rob swam with dolphins for free, but he also had a great white shark with him! 根据短文内容，选择最佳答案。 21．The writer starts the passage by _________.

It has five rows of up to 3,000 very white, very sharp teeth.”可知，文章开头就给出了一些数据。故选B。 22．细节理解题。根据“ It will eat almost anything that swims in the sea, from fish to dolphins to other sharks.”可知，大白鲨有时吃海豚。故选A。 23．细节理解题。根据“That was when Rob saw the great white shark. It was very close—only a few meters away…”可知，Rob最后才意识到，当他们游泳时，一条鲨鱼就在他们附近。故选B。 24．细节理解题。根据第二段和第三段可知，海豚们的行为是在保护Rob他们不被鲨鱼袭击。故选B。 B Over time, the cuckoo (布谷鸟) has learned to get other birds to care for its babies. The cuckoo is an amazing bird. Most birds lay their eggs and look after them until their babies hatch out. Then they feed their babies until they are ready to leave the nest. Some birds are not such good parents. Cuckoos lay their eggs in the nest of other birds and do not care for their own babies. They get other birds to act as the parents. The other birds raise the young cuckoos as well as their own babies! If the cuckoo egg hatches first, the baby cuckoo will often push the other eggs out of the nest so that it can get all the attention of its new mother. The young cuckoo sometimes even push the other babies out of the nest. The young cuckoo has a loud cry and is often bigger than the other baby birds, it will take all the food and the space in the nest. If the cuckoo lay around 25 eggs each year in the nests of other birds. This means that many other birds spend all their time looking after young cuckoos instead of their own babies. Some birds have learned to recognize the cuckoos’ eggs and they push them out of their nests. But the cuckoos have also found ways of fooling (欺骗) the other birds. They can change their eggs to make them look just like the other birds’ own eggs. 25．What has the cuckoo learned? A．Making a wonderful nest. B．Singing songs. C．Catching food quickly. D．Getting other birds to care for its babies. 26．What will most birds do after they lay their eggs? A．They will look after them until their babies hatch out. B．They will do nothing but leave them in the nest. C．They will push the eggs out of the nest. D．They will eat all the eggs. 27．What does the underlined words “hatch out” mean? A．Lay eggs. B．Eat eggs. C．Get out of the eggs. D．Push eggs. 28．If the cuckoo eggs hatches first, the baby cuckoo will often ________. A．push the other eggs out of the nest B．fly to find its own parents C．help to warm the other eggs D．do nothing but wait for food 29．Which of the following statements is TRUE? A．The young cuckoos look like the other babies in the nest. B．No birds can recognize the cuckoos’eggs and push them out of the nest. C．Some birds can recognize the cuckoos’ eggs and push them out of thenest. D．It’s impossible for cuckoos to lay eggs in the nests of other birds. 【答案】25．D    26．A    27．C    28．A    29．C 【导语】本文是一篇说明文，介绍了杜鹃鸟的产卵和孵化方式。 25．细节理解题。根据第一段中“Over time, the cuckoo (布谷鸟) has learned to get other birds to care for its babies.”可知，布谷鸟学会了让其他鸟类照顾它们的宝宝。故选D。 26．细节理解题。根据第一段中“Most birds lay their eggs and look after them until their babies hatch out.”可知，大多数鸟下蛋后照顾它们，直到它们的宝宝孵化出来。故选A。 27．词义猜测题。根据句中“Most birds lay their eggs and look after them until their babies...”可推测句意为“大多数鸟产卵并照顾它们，直到它们的宝宝孵化出来。” hatch out意为“孵出”，和“Get out of the eggs从蛋里出来”意思相同。故选C。 28．细节理解题。根据第三段“If the cuckoo egg hatches first, the baby cuckoo will often push the other eggs out of the nest so that it can get all the attention of its new mother.”可知如果布谷鸟蛋先孵化，小布谷鸟通常会把其他蛋推出巢外。故选A。 29．细节理解题。根据第四段中“Some birds have learned to recognize the cuckoos’ eggs and they push them out of their nests.”可知有些鸟能认出杜鹃的卵并把它们从巢里推出来，故选C。 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
