主题语境练16　选择性必修第一册　UNIT 5 自然生态 限时25分钟　 阅读理解　(2023·贵州六校联考)　体裁:说明文　主题语境:人与动植物　难度:★★★☆☆ 　　There are not only strange animals in the world; there are also some crazy plants. Cactuses grow in places that have very little rain. These plants don’t have leaves because plants lose water through their leaves. Cactuses want to keep water inside their bodies. If you are ever stuck in a desert, you can get water by cutting a cactus. The water is not very nice because it tastes bitter. Sharp thorns protect cactuses. This is why desert animals won’t eat them. Their roots are spread out very close to the top of the sand. Venus flytraps got their name because they trap and digest small insects in their leaves. They grow in wet places where the soil does not have the right food for the plants, so the plants have to catch their own food. Venus flytraps are small plants that have little white flowers. Mangrove trees are trees that are able to grow in salty water. As a mangrove gets taller, it grows roots from its branches. When it is fully grown, hundreds of roots hold the leaves above the salty water. Mangroves grow mainly in the shallow water of rivers, close to where the river runs into the sea. Trees do not need much salt and mangroves have special ways of releasing excess salt, to stop it damaging the tree. Other mangroves send the salt to be stored in the oldest leaves on the tree, so that when they drop off, the tree gets rid of all unwanted salt. Plants are able to change so that they can live in certain environments. 本文主要介绍了自然界中一些独特的植物。 1.What’s the tone of the article? A. Terrifying. B. Thrilling. C. Serious. D. Frightening. 答案与解析　C　推理判断题。 第二段介绍生长在少雨的地方的仙人掌。 第三段介绍维纳斯捕蝇草;第四段介绍能在咸水中生长的红树林。由此可知,作者是在介绍生物知识。因此作者的口吻是严肃的。故选C。 2.What does the underlined word “excess” mean? A. Poisonous. B. Costly. C. Extra. D. Bitter. 答案与解析　C　词义猜测题。由上句“树木不需要太多的盐”及“红树林有特殊的释放方式”可知,红树林不需要太多的盐,因此在盐水中生长的红树林有特殊的方式释放多余的盐。故画线词和 extra(额外的、多余的)含义相近。故选C。 3.Where can the text be found? A. In a science fiction. B
