Question

【題目】安德魯的媽媽看上去很年輕，經常被錯認為是他姐姐。

Andrew’s mother looks so young ________ his sister.

Answer 1

【答案】that she is often mistaken for

【解析】

此句用“so…that…”引導的結果狀語從句，表示“看上去如此年輕，以至于經常被錯認為是他姐姐”；從句的主語是she代替Andrew’s mother，是第三人稱單數；表示“錯認”用動詞短語mistake…for…;此處的謂語動詞是一般現在時的被動形式is often mistaken for。故答案為that she is often mistaken for。
