17、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(dòng)詞不定式”作定語，相當(dāng)于介詞＋關(guān)系代詞which引導(dǎo)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. 她沒有時(shí)間收拾行李。 It was a bad season in which

A.in order to have received B.in order to receive C.so as to be received D.so as to be receiving 提示:所有的禮物都應(yīng)立即被寄出去，當(dāng)然是為了使它們及時(shí)被收到。in order to和so as to都表目的，receive和gift之間因是被動(dòng)關(guān)系，所以so as to be received正確。 答案:C 講評(píng):首先要了解在這里so as to 和in order to是沒有區(qū)別的。選擇的關(guān)鍵在于動(dòng)詞不定式的時(shí)態(tài)和語態(tài)，可以先選擇一點(diǎn)入手，然后進(jìn)行對(duì)比。
