Do you find that the same letter can have different pronunciations in different words, while different letters may sometimes have the same pronunciation
c /k/ /s/

Today, let's learn more about how these letters 'c', 'ck', 'g', and 'x' can sound differently in various words.

輔音字母c在以下情況中常發/k/:
1. 在元音字母a、o、u前，如：car、cup等
2. 在輔音字母前，如：act、picnic等。
3. 在單詞末尾時，如：music、magic等。
輔音字母c在元音字母e、i或y前，常發/s/。

Can you add one more word to each group
cut city luck
Possible words:
jog change fix
Pronunciation
Watch the video and learn how we change a verb into the past tense.
We add -ed to the verb.
hunted played helped
Do the 'ed' endings in these verbs have the same pronunciation
huntedplayed
helped
/ d/
/d/
/t/
Now, let's find out how to pronounce -ed correctly after different verbs.
Pronunciation
Listen and repeat. Notice the pronunciation of -(e)d.
P51
2
talked picked helped stopped finished
moved climbed filled tried enjoyed
wanted visited tasted needed ended
The final sound of the verb determines the "-ed" sound.
* If the final sound is a voiceless consonant, "-ed" is pronounced as /t/.
* If the final sound is voiced (including voiced consonants and vowels), "-ed" is pronounced as /d/.
* If the final sounds are /t/ or /d/, "-ed" is pronounced as / d/.
讀音規則一般是：動詞的最后一個音決定了"-ed"的發音。清輔音后面讀作/t/，濁輔音和元音后面讀作/d/，/t/和/d/后面讀作/ d/。
/t/
/d/
/ d/
Pronunciation
What is a contraction
Let's learn how to pronounce some negative contractions.
A contraction is a combination of two separate words, with some letters omitted and replaced with an apostrophe. Contractions happen in informal speech and writing. They help make sentences more fluid and quicker to say.
縮寫形式是兩個獨立單詞的組合，其中一些字母被省略并用撇號(')代替。縮寫形式常用于非正式的口語和書面語中，它們使句子更流暢，讀起來更快。
Pronunciation

Tip:
答題時要嚴格依據文本，避免受到常識或自身主觀認知的干擾:
B選項企圖利用學生所熟知的“節約用水”這一常識來進行干擾。從常識角度而言，節約用水是正確且值得倡導的觀念，但在給定的文本內容里，并沒有任何直接表述或暗示指向這一點 ，所以該選項與文本內容不匹配，應予以排除。
