《密碼解謎》第四冊(第二版)練習冊第四冊向學生介紹複合詞、常見詞尾和音節類型。學生將學習複合詞由兩個較小的詞組成,組合在一起後可以構成一個意思不同的新詞。他們將練習加入詞尾 ful、-ing、-est、-ed 和 -ness 來組成新單字。
Explode the Code Book 4 (2nd Edition) Workbook 4 introduces students to compound words, common endings, and syllable types. Students learn that compound words are made up of two smaller words that when put together make a word with a different meaning. They practice adding the endings ful, -ing, -est, -ed, and -ness to make new words.
