1. Explain the usage of “when”, “while, “as”
T: They all mean “during the time that” and can be used to introduce a long action that started
before a short action.

2. Explain the differences between “when”, “while, and “as”
If the longer action is in the main clause, we often use “when” to join them. When there are two long actions, we often use “while”.
“As” can also be used to join two short actions that happen at the same time. 【設計意圖：使學生理解三個連詞的共同點和各自的不同點。】 Step 2 Practice 1. Fill in the blanks
Get the students to fill in the blanks with “when”, “while” or “as”. 2. Complete Part B on Page 98

Get the students to complete the survey with their own information. 2. Look and answer
Get the students to watch the pictures and answer the questions. 3. Look and say
Get the students to watch the picture and make dialogues in pairs.
