1．强调句的基本形式为：It is/was＋被强调部分＋that/who＋其他部分。被强调成分一般是主语、宾语、状语。当被强调部分指人时，用that，who均可；指事物或情况时用that(被强调的是时间或地点状语时，一般不用when，where)。强调句考查的重点是：强调句的句式变化，包括一般疑问句Is/Was it＋被强调部分＋that/who...和特殊疑问句What＋who/when/where/why＋is/was it＋that/who...
2．如果需要强调谓语，用助动词do，does或did。
[典例1] It was from only a few supplies that she had bought in the village ________the hostess cooked such a nice dinner.
A．where B．that
C．when D．which
[解析] 该句是一个强调from only a few supplies的强调句。该句可以转变为“The hostess cooked such a nice dinner from only a few supplies that she had bought in the village.”。在该句中有一个定语从句that she had bought in the village，用来修饰限定先行词a few supplies。做题的时候可以先把该定语从句忽略。
[答案] B
