高考英語單元知識點復習Unit 10
a.attended b.accepted c.received d.enjoyed
提示:本題通過語境考查動詞辨析。橫線后面的it起著關鍵性的作用，代替的應該是party，而不能是復數名詞invitations，所以使用attend，表示“參加晚會”。
答案:a

很遺憾，她讓我們大失所望。

a.let out b.took care

答案:a
句型
“介詞+which+動詞不定式”作定語
講:請觀察下面教材原句:
...and she had only $1.87 with which to buy jim a present.
……她只有一美元87美分用來給吉姆買禮物。
本句型為“介詞+which+動詞不定式”作定語，相當于介詞＋關系代詞which引導的定語從句。本句可以改為:she had only $1.87 with which she could buy jim a present.
例:she had no time left in which to pack her things.
