中等ENGL-WRIFMT-009
題目要求寫一封 email 給同學，邀請他參加活動。以下邊句最符合語域？
A. I am writing to formally invite you to participate in the forthcoming event.
B. We're holding the event next Friday — fancy joining us?✓ 答案
C. Pursuant to our discussion, kindly revert to us at your earliest convenience.
D. You are hereby invited to attend the said function.
解說
寫給同學的 email 屬非正式或半正式，縮寫與直接邀請最自然。A 與 C、D 過度正式，甚至屬商業書信用語，與讀者身份不符，會被視為語域錯配。
