6、引导的宾语从句。连接代词及连接副词引导的宾语从句相当于特殊疑问句，连接词都在从句中担当一定的成分。I dont know what I should do next.(what引导宾语从句，并在从句中作宾语)我不知道下一步做什么。I wonder who will play in the basketball match.(who引导宾语从句，并在从句中作主语)我不知道这场篮球赛谁会上场。Ask him which he wants，the big one or the small one.(which引导宾语从句，并在从句中作宾语)问问他想要哪一个，大的还是小的。You can choose
