很多同學讓我講一講4000 essential english words 這套教材，今天就詳細介紹一下這套教材，附帶導學視頻，具體如下：
一、教材介紹
The 600 words in each book of this series along with the additional target words presented in the appendices included in the first three books of the series are the most useful words in English. They were found by analysis of a collection of English course books from various levels in the primary, secondary and tertiary school systems. The words included in this series were chosen because they occurred many times in different levels of these materials. Because of the way that they were chosen, these words have the following characteristics:
1. They are useful in both spoken and written English. No matter what English course you are studying, the words in these books will be of value to you.
2. Each word in these books is a high-frequency word. This means that the effort in learning the words is well repaid by the number of times learners have a chance to encounter or use them.
3. These books as a whole cover a large proportion of the words in any spoken or written text. They cover at least 80% of the words in newspapers and academic texts, and at least 90% of the words in novels. They also cover at least 90% of the words in conversation.
上面是來自官網的英文版介紹，整套教材有6本書，包含4000 個使用頻率最高的單詞，每本書包含600個詞，30個單元，每個單元20個單詞，同時有整片文章針對這20個單詞的運用和練習，是一套設計十分合理的英語書籍。

四、打卡學習課程介紹
先看老師講解單詞的視頻，大概二十多分鍾（主要是詞根詞綴講解單詞的構成），然后在速記這個單元的單詞，之后就是自己做課后的練習，然后對照參考答案，將錯的單詞抄寫在錯題本上，最后將整個內容拍照上傳到打卡小程序里完成學習打卡，之后會收到老師的點評和鼓勵的話。我們也有自己的學習群互相監督學習，這樣下來學習起來就很輕松。附上打卡的照片
