問答題請認真閱讀下列材料，并按要求作答。
 
 請根據上述材料完成下列任務：
 （1）列舉五種詞匯呈現的方法。
 （2）如指導小學生學習試擬定教學目標。
 （3）依據擬定的教學目標，設計導入和呈現環(huán)節(jié)的教學活動并說明設計理由。
 

參考答案：
 （1）詞匯呈現方法
 ①實物呈現。用實物教單詞，借助直觀教學手段能動員學生運用各種感覺器官來感知和認識客觀現象，讓學生把單詞和實物聯(lián)系起來，從而較容易地掌握生詞。
 ②圖片呈現。對于一些不能用實物進行教學的單詞，圖片是很好的教學輔助手段。課文插圖、教師自制的掛圖、剪貼畫、簡筆畫等都可以用來再現物體，創(chuàng)設情境。
 ③定義呈現。用直接下定義的方式解釋單詞的意義，然后教授單詞。
 ④動作表情呈現。對于一些如run,walk之類的單詞，可以借一些形象的動作或生動的表情呈現。
 ⑤描述呈現。結合詞匯表示的事物的特點來呈現單詞。
 （2）Teaching Aims
 Knowledge aims:Students can learn some new words,such as:cloud,sun,rain,vapor and stream.
 Ability aim:Students can use the new sentence
 “Where does the rain come from?”to discuss the formation of rain.Their listening and speaking ability will have an improvement through discussion in groups and pair work.
 Emotional aim:Students can have a desire to know more about nature and develop their awareness of Environmental protection.

 利用多媒體展示下雨的過程，營造輕 松愉悅的課堂氛圍。通過設疑，激發(fā)學生對雨水的形成展開積極思考，從而引出新課。
 Presentation（呈現環(huán)節(jié)）:
 ①Teaching“rain”

 [設計意圖]
 使用新句型一步步發(fā)問，引導學生學習新單詞，讓學生認識單詞之間的聯(lián)系并理清水循環(huán)的過程。圖片、簡筆畫和視頻并用，加深學生的感官認識，幫助學生更好地理解新知。
