The activities in "4000 Essential English Words" are specially designed to make use of important learning conditions. Firstly, the words are introduced using sentence definitions and an example sentence. The activities that follow in the units encourage learners to recall the meanings and forms of the words. Some activities also make the learners think about the meaning of the words in the context of a sentence—a sentence different from the sentences that occurred in the introduction of the words. Moreover, each unit ends with a story containing the target words. While reading the story, the learners have to recall the meanings of the words and suit them to the context of the story. Such activities help learners develop a better understanding of a common meaning for a given word which fits the different uses.
