Ⅰ.单句语法填空
1.(2021·辽宁铁岭市高三一模)Therefore, performing the lion dance became a custom ________ people could pray for good luck, safety, and happiness.
【答案】 where
【解析】 考查定语从句。句意:因此,舞狮成了一种习俗,人们以此来祈求好运、平安和幸福。此处为定语从句修饰先行词custom,先行词在从句中作地点状语,应用关系副词where引导。故填where。
2.(2021·辽宁辽阳市高三一模)All cars will have breathalyzers(呼气酒精测量仪)with ________ drivers won’t be allowed to drive if they have drunk too much alcohol.
【答案】 which
【解析】 考查定语从句。句意:所有的汽车都将配备酒精测试器,如果司机喝了太多酒,就不允许驾驶。定语从句中缺少介词with的宾语,在介词with之后,且先行词为breathalyzers,所以应用关系代词which。故填which。
3.(2021·新疆高三一模)Laurent explained ________ he wanted to create artificial hearts in the future.
【答案】 why
【解析】 考查名词性从句。句意:Laurent解释了他想在未来制造人工心脏的原因。此处动词explained后面是why引导的宾语从句,引导词在从句中作原因状语,用why引导该从句。故填why。
