"DUO 3.0/CD for Beginners" Price: ¥2800 #Books #Language/English This is an audio CD that allows even those who are not good at English to learn it enjoyably and reliably. It uses a careful recording pattern: "Headline English sentence and Japanese translation → Headline English sentence (slow speed) → Headline word → Headline English sentence again (natural speed)." Also, the narration is not monotonous, as is often the case with audio materials, but is read with emotion by native speakers according to the content of the sentences, so you can continue learning without getting bored. Learning a language is much easier by listening than by reading and memorizing. As you study DUO3.0 section by section, listen to this CD repeatedly and firmly master the "actual sounds" of each word and idiom. Inspired by the Japanese "Iroha Uta," 1600 important modern English words and 1000 important idioms have been condensed into 560 English sentences without duplication. Even if combined without duplication, it is meaningless if the English sentences are unnatural and awkward. All the headline English sentences in DUO3.0 were completed with 15 native speakers, including 3 American university professors, and are "English sentences worth memorizing."
