______ parents say and do had a lifelong effect on their children. A．That B．Which C．What D．As

Answer 1

C

what引导主语从句，在从句中作say和do的宾语，表示“父母说的话和做的事”。which和what都可以引导宾语从句，并都可以在宾语从句中作主语、宾语、定语或表语，但which指已知中的未知，范围较窄，所指事物比较明确，含有选择的意味。what却指未知，范围较宽，所指事物比较含糊。that引导宾语从句时，在从句只起连接作用不担当任何成分。as用于引导定语从句、原因状语从句、让步状语从句、时间状语从句等。
