Special difficulties 難點

    Exercises B
    1. He is the man we have heard about so much.
    2. The shelf you put those books on has collapsed.(vi.倒塌, 崩潰, 瓦解)
    3.Whom did you receive a letter from?
    特殊疑問句中whom?不能省略(本句)。
    定語從句中Which以及指代人的做賓語的Whom, 在非正式用法當中可以省略。
    省略時,介詞不能前置到關系代詞Whom, Which前,只能用于非固定的動詞短語后面。
    固定的動詞短語
    look?for:尋找(去掉for后look沒有尋找的意思,所以介詞for不能前置)
    非固定的動詞短語
    look?at:注視
    live?in:居?。ㄈサ鬷n后live仍有居住的意思,所以介詞in可以前置)
    This is the old house in which he lived. = This is the old house he lived in.
    4.This is the road we came by?
    5.Where is the pencil you were playing with?
