34、ose a suitable Christmas present for her father。2to please动词不定式做状语。3a 表示“经历”，是可数名词，所以用不定冠词a。4pushedor连接并列谓语，push在时态上与step保持一致，用一般过去时。5wherecounter是先行词，定语从句中缺少地点状语，故用where引导。6choice形容词性物主代词后应用名词，choose的名词形式是choice。7onon sale意为“出售”。8him此处指代简的父亲，故用第三人称代词宾格形式him。9atat table意为“在进餐”。10was informedinform与主

So have you prepared well for the exam?Alice: Sure.1_2._3._4._5_6._7._8._9_10._答案：1tired考查词性转换。句意：Jim，为什么你看起来很累？此处tired作表语。2coming考查非谓语动词。根据语境可知，此处表示“即将来临的考试”，所以要用coming作定语。3for考查介词。短语be well prepared for.意思是“为做好充分的准备”，所以要用介词for。4used考查固定搭配。句意：事实上我过去睡得很好。表示过去惯常做某事情，而现在不做了，要用used to do sth.。
39、5make考查动词短语。make a noise“制造噪音”，所以此处要用动词make。6the考查冠词。在西洋乐器名词前要加定冠词the。7which/that考查关系代词。句意：他举行了一场派对，一直持续到深夜。此处是一个定语从句，先行词为party，且定语从句中缺少主语，故要用关系代词which/that。8to stop考查动词不定式。句意：为什么你不去阻止他们呢？此处用动词不定式表目的。9thought考查动词时态。句意：我原以为舞会将在11点之前结束。表示“原以为”，要用一般过去时。10trouble考查固定短语。give sb. trouble“给造成麻烦”。故应填trouble。
