Unit 4 Amazing Plants and Animals 七选五专项训练 Passage 1 主题：Special Talents of Wild Creatures 野生动物的特殊本领 Many wild animals have surprising skills to live in the wild. 1.________ They use these skills to keep safe, find food or raise their babies. Some animals are good at hiding themselves. For example, chameleons can change their skin colours. 2.________ Other animals look like leaves or dry sticks so enemies cannot find them easily. Some animals have wonderful body‑built “tools”. Beavers have strong sharp teeth. 3.________ They build safe houses out of wood in rivers. Many animals also have great memory. Squirrels hide lots of nuts in different places in autumn. 4.________ They can find most of their food even under thick snow in cold winter. 5.________ Learning about their special talents helps us know more about nature. Options A. They can cut tree branches for their daily life. B. Not all animals need to look for food in winter. C. These special abilities help them live in hard environments. D. They can mix into different backgrounds to stay away from danger. E. They remember where they put those food seeds clearly. F. All wild animals can change their body colours at will. G. It is really amazing to see how clever wild animals are. Passage 2 主题：Survival Skills of Desert Plants 沙漠植物生存智慧 Deserts are hot and dry with very little rain. Living in such places is a big challenge for plants. 1.________ Many desert plants have short but wide roots under the ground. 2.________ As soon as the rain comes, their roots take in water quickly. Some plants grow thick leaves covered with something like wax. 3.________ In this way, they won’t lose too much water under the strong sun. Some desert flowers only grow for a very short time. 4.________ When rain falls, they grow fast, flower and produce seeds in several weeks. Then the parent plants die, but seeds wait for the next rain. 5.________ They teach us how life tries hard to live even in terrible conditions. Options A. The wax stops water from running out of leaves. B. Few kinds of plants can live in deserts at all. C. They spread far under the sand to catch every little bit of water. D. Their seeds can sleep in dry sand for many years. E. However, plenty of plants have found clever ways to survive. F. All desert plants can store plenty of water inside their stems. G. Desert plants are great examples of the power of life. Passage 3 主题：Animal Group‑living 动物的群居生活 Lots of animals choose to live in groups instead of living alone. 1.________ Living together brings them lots of advantages. Living in groups makes it easier for animals to keep away from danger. When some members eat, others watch out for enemies. 2.________ So the whole group can get warnings early. Group life helps animals get food as well. Wolves hunt together. 3.________ They can catch big animals that one wolf cannot deal with alone. Some group‑living animals look after each other’s babies. For example, elephants live in big family groups. 4.________ The whole group protects little baby elephants. 5.________ But group‑living also brings problems such as disease spreading. Options A. Working together gives them more hunting power. B. Each animal in the group always lives completely separately. C. Not every animal likes to stay with other members. D. Adults take turns to care for all the young elephants. E. Once danger appears, they send quick signals to others. F. It is clear that living in groups brings many good points. G. All animals must live in big groups to stay alive. Passage 4 主题：Plants That “Move” 会 “运动” 的植物 We usually think plants cannot move like animals. 1.________ Some plants can make quick movements when they get touched. The mimosa plant is well‑known for its quick reaction. 2.________ Soon its small leaves close up and branches drop down. Scientists think this action may frighten small insects away. The Venus flytrap is another moving plant. It has special leaves like open mouths. 3.________ The leaves will shut fast and trap the bug inside. These quick movements do not mean plants have muscles like humans. 4.________ They change water pressure inside their cells to finish these actions. 5.________ They show us plants are far more lively than we imagine. Options A. When an insect touches its inner small hairs, something happens. B. But a number of plants can make fast movements of their parts. C. When you touch its soft leaves, you will see strange changes. D. They get strong muscle power to finish fast movement. E. They finish movement through special cell‑water changes. F. All plants can move their leaves quickly when touched. G. Such amazing plant behaviours are worth our attention. Passage 5 主题：Protect Local Wildlife 保护本土野生动植物 Local wildlife means the plants and animals that naturally live in one area. 1.________ They keep the local ecosystem balanced. However, local wildlife faces different kinds of trouble. Some foreign plants or animals come into this area. 2.________ They take food and living space away from local creatures. Human activities also bring trouble. People build more houses and roads. 3.________ Many local animals lose their homes. We do not need difficult big projects to help local wildlife. 4.________ We can grow native flowers in our gardens and stop throwing rubbish into wild areas. 5.________ Small shared efforts can make a real difference for local wildlife. Options A. They play important roles in our home environment. B. We can start with small simple actions in daily life. C. They cannot live well in this new environment at all. D. This cuts down the living space for wild plants and animals. E. These foreign species sometimes grow too fast with no natural enemies. F. Foreign wildlife is always more beautiful than local wildlife. G. Everyone is able to do something for local wild plants and animals. 参考答案与解析 Passage 1 答案：1.C 2.D 3.A 4.E 5.G 1.C：承接很多野生动物拥有野外生存的惊人本领，C “这些特殊本领帮助它们在严酷环境生存”，引出下文举例。 2.D：前文变色龙可以改变皮肤颜色，D “它们可以融入不同背景远离危险”，解释变色的作用。 3.A：河狸有着锋利坚硬的牙齿，A “它们可以啃断树枝维持生存”，衔接后文用木头筑巢。 4.E：松鼠秋天储存坚果，E “它们可以清晰记住存放食物种子的位置”，对应后文雪地找到食物。 5.G：结尾总结，G “看到野生动物如此聪慧真的很奇妙”，引出了解自然。 干扰项：B 并非所有动物冬天都不需要觅食；F 全部动物都可以随意变色，表述错误。 Passage 2 答案：1.E 2.C 3.A 4.D 5.G 1.E：沙漠干旱少雨，对植物生存是巨大挑战；E “然而很多植物演化出聪明的生存方式” 开启下文。 2.C：沙漠植物根系浅但铺展广，C“根系在沙子下延伸，捕捉每一丝水分”，承接下雨快速吸水。 3.A：部分植物叶片带有蜡质层，A “蜡质可以阻止叶片水分流失”，解释蜡质层的功能。 4.D：部分沙漠花期很短；D “种子可以在干燥沙土中休眠很多年”，对应下雨快速发芽开花。 5.G：结尾升华，G “沙漠植物是生命力量的绝佳范例”。 干扰项：B 几乎没有植物可以在沙漠生存；F 所有沙漠植物茎内都储存大量水，不符合事实。 Passage 3 答案：1.C 2.E 3.A 4.D 5.F 1.C：很多动物选择群居而非独居；C “并不是所有动物都喜欢和同类待在一起”，引出群居的好处。 2.E：一部分动物觅食，一部分警戒；E“危险出现时，它们迅速向同伴传递信号”，实现提前预警。 3.A：狼集体捕猎；A “合作给予它们更强的捕猎能力”，可以捕获单独无法对付的大型猎物。 4.D：大象群居；D “成年大象轮流照料所有幼象”，对应群体保护小象。 5.F：F “很明显群居带来很多益处”，后半句转折群居也会带来疾病传播等问题。 干扰项：B 群体内部动物完全分开生活；G 所有动物必须群居才能存活，逻辑错误。 Passage 4 答案：1.B 2.C 3.A 4.E 5.G 1.B：我们一般认为植物不能像动物一样移动；B “但是不少植物可以让自身器官快速运动”，引出下文。 2.C：含羞草反应很特别；C“当你触碰柔软叶片，就会看到奇妙变化”，承接叶片闭合下垂。 3.A：捕蝇草长有嘴巴一样的叶片；A “昆虫触碰到内部细毛就会触发反应”，叶片迅速闭合困住虫子。 4.E：这些快速运动并不是因为拥有肌肉；E “它们依靠细胞水分变化完成运动”。 5.G：G “这些奇妙的植物行为值得我们关注”，结尾总结，植物远比想象更有活力。 干扰项：D 它们依靠强大肌肉完成快速运动；F 所有植物被触碰都可以快速动叶子，错误。 Passage 5 答案：1.A 2.E 3.D 4.B 5.G 1.A：本土野生动植物是自然栖息在此地的物种；A “它们在我们生存环境中扮演重要角色”，维持生态平衡。 2.E：外来动植物入侵，E “缺少天敌的情况下外来物种会疯狂繁衍”，抢夺本土生物食物与栖息地。 3.D：人类修建房屋道路；D “压缩了野生动植物的生存空间”，很多动物失去家园。 4.B：保护本土生物不需要宏大工程；B “我们可以从日常生活简单小事做起”，后文列举庭院种本土花、不乱扔垃圾。 5.G：G “每个人都可以为本土动植物做一点事”，承接众人微小行动带来巨大改变。 干扰项：C 外来物种在新环境完全活不了；F 外来物种永远比本土物种更美，表述错误。 学科网（北京）股份有限公司 $
