‎ 必修2　Unit 4　Wildlife protection ‎ ‎ ‎　　Wildlife is on the decrease.Tigers can now only be found in secure reserves or distant mountains.Hunters kill them without mercy for fur to make coats and carpets.Even some insects are dying out.According to an inspection，an insect，which contains a drug against mosquitoes' biting，is disappearing from a zone，where farmers are employed to catch them in large numbers.This has affected the natural balance，badly harming the environment.To our relief，people are aware of the importance of wildlife protection.They have responded actively to this situation，thus preventing it getting even worse.‎ ‎ ‎ 默写识记 ‎◆默写单词 ‎1.decrease vi.& vt. 减少；(使)变小；或变少 ‎2.respond vi. 回答；响应；做出反应 ‎3.distant adj. 远的；远处的 ‎4.relief n.
