A worksheet dealing with phonetics and some of the major difficulties my students usually have (maybe the same as yours). There are 7 exercises to differentiate vowel and consonant sounds, to differentiate z and s sounds an three exercises with the ending “ed” sound of regular verbs in the past. After the students do the exercises, they’ll find the transcriptions on the second page for auto-correction. The teacher may want to check it orally after their own correction. The worksheet is completely editable / correctable to better fit your needs or your students’ vocabulary and level. Hope it’s useful. Thanks for downloading and have a nice day!
