介詞短語(yǔ)就是由多個(gè)詞構(gòu)成的介詞，如because of，in spite of等；固定搭配則指習(xí)語(yǔ)和一些常見(jiàn)的固定用法，即由名詞、形容詞、動(dòng)詞等和介詞或者副詞構(gòu)成的短語(yǔ)，如influence on, different from, rely on 等。無(wú)論是介詞短語(yǔ)還是固定搭配，考點(diǎn)常常對(duì)準(zhǔn)介詞，出現(xiàn)介詞誤用的情況；除此之外，對(duì)固定搭配的考查也常常涉及搭配中的冠詞和名詞單復(fù)數(shù)等問(wèn)題，如將in contrast誤用為in the contrast，keep one’s words誤用為keep one’s word等等。
　　例題精析：
　　例1： But to sociologists, to be
　　human is to be cultured, because of culture is the common world S7.______
　　of experience we share with other members of our group.
　　解析：分析句子的結(jié)構(gòu)可知，because of 后面是一個(gè)完整的句子。當(dāng)表示原因時(shí)because of 后跟名詞，because 后跟句子，所以此處的of應(yīng)該去掉。
　　例2：If you are sending your CV electronically, check the
　　formatting by sending it to yourself first. Keep up S8_________
　　the format simple.
　　解析：keep up意為“堅(jiān)持，維持”；keep表示“保持”，可以在后面加賓語(yǔ)及其補(bǔ)足語(yǔ)。
　　例3：As we know, smoking not only gives harm to smokers’ health, 1. __________
　　but also non-smokers who live with them.
　　解析：此處考查固定搭配do harm to，意為“對(duì)…有害”，所以此處的gives應(yīng)改為does。
　　例4：There may be sound medical reasons for accepting electrical
　　shock treatment, but such reasons are totally dependent in the balance of 75. ____risks and benefits for the patients.
　　解析：dependent on 意思為“依靠，依賴(lài)”，而沒(méi)有dependent in 這種用法。所以這里應(yīng)該將in改為on。
