This unit is the second unit of the first volume of the third grade English textbook published by People's Education Press. The theme of this unit is color. In addition to color vocabulary, this unit will continue to learn how to introduce and greet others. The main scene diagram shows the key sentence patterns of this unit about introducing and greeting others through the scenes that children encounter when they draw.

This unit is divided into three parts: A, B, C ... Part A contains three pages and is divided into three categories. The first lesson includes situational dialogues and exercises. Miss White is introducing Miss Green to Mr Jones. Present the introducer's sentence: this is ... and greetings: good morning. Next, students should draw characters and introduce the people in the picture with key sentences. In the second class, let's learn the names of four colors: red, yellow, green and blue. Textbooks lead to words and sentences by children observing the color of rainbows after rain: I see green. Students can practice color words through the explanation of "Let me see green" in "Let's do it". In the letter and sound part of the third class, students begin to learn the glyph, writing and pronunciation of the four letters of ABCD.
