The topic made students creative and interested. They showed their ideas in the posters. Skills such as getting information, designing, and working in a team got better. Also, students became more aware of protecting the environment. But there were problems. At that time, it took too long to collect information at the beginning, so it ended too quickly, and the quality of the posters was not very good. I didn't use many different resources to help students get more information. The way of judging a poster was too simple. I only looked at how nice the posters were, but didn't think about other things. To make it better, I will make better preparations next class and I will judge the posters in different ways.【Language Abilities】1.Use words and expressions in the unit to talk about natural wonders.2.Use comparatives and superlatives to describe natural places.3.Explain the importance of natural world.【Culture Awareness】1.Cultivate students’ curiosity and love for nature.2.Develop students' awareness of protecting the environment.【Quality of Thinking】1.Develop students’ ability to observe and summarize through describing the colours of their hometowns.2.Think critically about the effects of human activities on nature. 【Learning Abilities】1.Students can cooperate with the teacher and think actively in class.2.Students know how to interrupt others politely during the conversation.【Class Hour Division】Five periods第一课时Starting out&Reading第二课时Grammar第三课时Listening and Speaking第四课时Reading for writing第五课时Presenting ideas&ReflectionI can talk about different kinds of natural wonders.I can get key information about the natural landscape of the Tibetan Plateau.I can find out the beauty of my hometown.情况加法例词一般情况直接加词尾small smaller smallest以e结尾的词加-r，及-stbrave braver bravestlarge larger largest以“辅音+y”结尾的词变y为i，再加词尾busy busier busiesthappy happier happiest以一个辅音字母结尾的词将该辅音字母双写，再加词尾hot hotter hottestbig bigger biggest原级比较级最高级carefulmore carefulmost carefulactivemore activemost activelikelymore likelymost likelydifficultmore difficultmost difficultbeautifulmore beautifulmost beautifuleffectivemore effectivemost effective原级比较级最高级carefulless carefulleast carefulselfishless selfishleast selfishdangerousless dangerousleast dangerousnecessaryless necessaryleast necessary原级比较级最高级good, wellbetterbestbadworseworstmuch, manymoremostlittlelessleastfarfarther, furtherfarthest, furthestoldolder, elderoldest, eldestI can master the usage of comparatives and superlatives.
