题目内容
20． I hate it，I have to go to the dentist's regularly．（ ）| A． | Much as | B． | Only if | C． | Now that | D． | Much while |
分析 尽管我很不喜欢，但我还是不得不定期去牙科诊所．
解答 答案：A 句意表达的是转折；only if只有，now that既然，much while错误搭配；选项中as表示尽管，引导让步状语从句，相当于although；as引导让步状语从句时，句子要部分倒装．故选A．
点评 从属连词是连词的一种，用来引导名词性从句和状语从句．大致可分为三大类：that（无词义，不做成分）if，whether （表达是否的意义，但不做句子成分）； 连接代词：who，whom，whose，what，which，whatever，whoever，whichever（有词义，在句子中可作主语、表语、宾语）；连接副词：when，where，why，how，how many，how long，how far，however，whenever，wherever （有词义，作从句的状语）．本题考查as表示让步，学习时，要注意区分和掌握．
