Ⅴ.单元词汇整合——背诵下面短文(黑色字体为本单元必备词汇) Wildlife came into existence billions of years ago，which used to live in harmony with each other. However，at present, what we are concerned about is that animals are dying out at an alarming rate, 75 species every day on average. This is because human beings don't observe animal protection laws. Animals are being hunted, shot and attacked illegally so that people can obtain their skin，fur or other organs. Furthermore，not only do human activities lead to the reduction of animal habitats but also they cause the rise of global temperature, which threatens the survival of some animals，especially those species living in the polar regions. They make a living by hunting or fishing. So the ocean creatures are in danger due to the rapid melting of ice and they have difficulty adapting to the alarming changes. We must be aware that the extinction of masses of animals does great harm to us. Only if the authorities take effective measures immediately can we make progress in wildlife protection. Now, more nature reserves are being built to preserve endangered animals from extinction. ★本单元我学到了哪些语法规则？ _________________________________ _________________________________ ★本单元我学到了什么写作手法？ __________________________________ __________________________________ $
