Pronouncing fricatives properly
The pronunciations of the fricatives ( 摩擦音 ) in each group are difficult to distinguish. Listen carefully and check (✔) the words you hear. Then read these words and try to make clear their differences.
Tips
发 /f/ 和 /v/ 这两个摩擦音时，上齿应接触下唇。发 /θ/ 和 /ð/ 这两个摩擦音时，舌尖应置于上下齿之间。发 /s/ 和 /z/ 这两个摩擦音时，舌尖应抵齿龈。另外，因为 /v/、 /ð/ 和 /z/ 这三个音是浊辅音，读时声带应振动。
1 few — view
3 fine — vine
5 rice — rise
7 sick — thick
9 mouse — mouth
2 safe — save
4 bath — bathe
6 bus — buzz
8 sing — thing

Tips
/f/ 和/v/ /f/ 和/v/ 是唇齿音。发/f/ 时，上齿轻轻咬住下唇内侧，将气流从唇齿的缝隙间轻轻吹出来；/v/ 的发音和/f/ 大致相同，发此音时，上齿轻轻咬住下唇内侧，再用力将气从唇齿的缝隙中吹出来，但需要振动声带。
/θ/ 和/ð/ /θ/ 和/ð/是齿间音。发/θ/ 时，双唇微开，舌头伸出来，上下齿轻咬住舌尖，将气流从牙齿的缝隙中吹出来。发/ð/ 时，双唇微开，上下齿轻咬住舌尖，让气流尽量被上下齿堵住，只允许少量气体从牙齿缝隙中吹出来，同时振动声带发出声音。

Tips
/s/ 和/z/ 是齿龈音。发 /s/ 时，舌尖及舌中靠近上齿龈，其间形成窄缝，气流从窄缝中流出，摩擦成音，但只送气不振动声带；发/z/ 和发/s/ 时的舌形和口形相同，不同的是发此音时声带需要振动，但不送气。
