Teacher Josh: 300 Commonly Used English Idioms Ideal for Improving IELTS and TOEFL Scores by
"In a pickle. Chip off the old block. At the drop of a hat. Idioms are expressions that are used every day but don't mean what the words seem to indicate. No spring chicken, for example, has nothing to do with chickens. Rather, it means not being young anymore. Teacher Josh: English Idioms explains what 300 of the most widely used English idioms mean in an easy-to-learn, memorable way. The entry for each idiom features a cartoon that depicts how it is used, plus an example and explanation in English and Mandarin. Readers can also scan a QR code to access a funny video by TeacherJosh, further explaining the idiom in Chinese and English."
