Yes，you are right.是[ð]，发音时，舌尖轻触上齿背，气流由舌齿间送出，形成摩擦音，发音时声带不震动。同学们你们记住这两个音了吗？字母组合th在单词里的发音有两种，一种是[θ],另一种是[ð ]。下面我们就运用这个规律来练练手吧，请圈出我读到的单词，你准备好了吗？开始喽！That is my brother .He is thin .Thursday is his eleventh birthday .His father is three years older than his mother .同学们，你圈对了吗？嗯，你真厉害。下面我们来挑战一下自己Challenge yourself!：用我们以前学过的字母的发音规律和我们今天所学的字母组合th 的发音规律来拼写一些单词吧！
