6、liked best.注意：疑问句中主语之前的助动词若是 do/does/did，变为宾语从句时，要先将其去掉，谓语动词再根据时态做相应的变化。(4)特殊疑问词在句中做主语，变为宾语从句时语序不变(时态应做相应变化)。如：Who can answer the question ？ The teacher asked.Theteacher asked who could answer the question.(5)特殊疑问句变为宾语从句后，用问号还是用句号完全取决于主句的句式：若主句为陈述句或祈使句，句末就用句号；若主句是疑问句，句末就用问号。如：I dont know when we sha
