Do you know what does the letter “i” sound? /ai/ or /i/?【设计意图】通过听和读让学生初步感知字母”i”的发音，为后面的学习作铺垫。2.Point and soundT:Lets check it together! First ,look at the four words,can you read?Pig, p-i-g-pig,pig.（图片先出，再出单词）Is it pig again? No, its big. Good pronunciation. Can you tell me what is the position of letter “i”? Yes, its in the middle of the words. Now do you know what does the letter “i” sound? Yes, letter “i” sounds/i/ in the middle of the words.
