Section Ⅲ　Grammar and usage 　　　(语法项目——主语从句) 语境中体悟 It is true that① experiences are acquired through our journey of life.What② we believe and how③ we look at things and people around us are based on all our experiences in life.Despite the fact that things and life are the way they are, we all have different opinions and beliefs about everything and everybody.Other people have opinions about us as well.But what④ really matters is the opinion we have about ourselves.You choose to accept and follow what other people believe, but whether⑤ you want to become yourself or live according to the reality of life is for you to decide. [语法入门] ①处从属连词that引导的从句为真正的主语，that在从句中不作成分； ②处连接代词What引导主语从句，并在从句中作宾语； ③处连接副词how引导主语从句，并在从句中作状语； ④处连接代词what引导主语从句，并在从句中作主语； ⑤处从属连词whether引导主语从句，在从句中不作成分。 学案中理清 主语从句就是在复合句中作主语的从句，通常置于句首，也可用形式主语it代替，而将主语从句后置。 一、主语从句的连接词及其句法功能 1．连接词that和whether/if (1)that引导主语从句时，在从句中不充当任何句子成分，也没有实际意义，只起连接作用，但不可省略。 (2)whether/if引导主语从句时，在从句中不充当任何句子成分，只起连接作用，意为“是否”，不可省略。 (3)whether引导的主语从句既可放在句首也可放在句尾，但if引导的主语从句不可以位于句首，可用it作形式主语，从句后置作真正的主语。 2．连接代词(who、whose、whom、what、which、whichever、whoever、whomever、whatever等) (1)连接代词引导主语从句，在从句中可以作主语、宾语、表语或定语。 (2)who引导的主语从句强调一件事情，而whoever引导的主语从句强调人。 3．连接副词(when、where、how、why、whenever、wherever、however等) 连接副词引导主语从句，在从句中作状语。 [对点练]　 (1)用适当的连接词填空 ①(2024·新高考Ⅰ卷)What worked on a veterinarian seemed likely to work on his patients. ②What comes next is the endless series of steps. ③Your support is important to our work.Whatever you can do helps. ④How we understand things has a lot to do with what we feel. ⑤Why John was late for the class has been unexplained. ⑥Which part of the country he will travel to needs discussing. ⑦Where/When the English party will be held has not yet been decided. ⑧Every year, whoever makes the most beautiful kite will win a prize in the Kite Festival.
