Activity 1 Reading for Main Idea
What does the passage mainly talk about?
A. Sharing the difficulty in learning different English words well.
B. Instructing how to spell difficult English words correctly.
C. Analyzing the reasons for inventing the English language.
D. Showing how interesting and creative the English language is.
答案：D
解析：文章通過列舉英語中諸如“seasick/airsick/carsick”“burn up/burn down”等用法，展示了英語語言的趣味性和創造性，D選項符合主旨。A選項“學習困難”、B選項“拼寫指導”、C選項“發明原因”均非文章重點，所以選D。
Activity 4 Structural Analysis
1. While we're doing all this traveling, we can get seasick at sea, airsick in the air and carsick in a car, but we don't get homesick when we get back home. (Para. 2)
[分析] 本句中 While 和 when 均引導________從句；but 為________連詞，連接兩個分句。
[翻譯]
答案：時間狀語；并列
翻譯：當我們進行所有這些旅行時，我們在海上會暈船，在空中會暈機，在車里會暈車，但當我們回到家時不會想家。
解析：“While we're doing all this traveling”和“when we get back home”均修飾動作發生的時間，是時間狀語從句；“but”連接前后兩個并列分句，表示轉折關系。

條件/時間狀語
