   一、强调句句型
    1. 陈述句的强调句型:it is/ was + 被强调部分(通常是主语、宾语或状语)+ that/ who(当强调主语且主语指人)+ 其他部分。
    e.g. it was yesterday that he met li ping.
    2. 一般疑问句的强调句型:同上,只是把is/ was提到it前面。
    e.g. was it yesterday that he met li ping?
    3. 特殊疑问句的强调句型:被强调部分(通常是疑问代词或疑问副词)+ is/ was + it + that/ who + 其他部分?
    e.g. when and where was it that you were born?
    4. 强调句例句:针对i met li ming at the railway station yesterday.句子进行强调。
    强调主语:it was i that (who) met li ming at the railway station yesterday.
    强调宾语:it was li ming that i met at the railway station yesterday.
    强调地点状语:it was at the railway station that i met li ming yesterday.
    强调时间状语:it was yesterday that i met li ming at the railway station.
    5. 注意:构成强调句的it本身没有词义;强调句中的连接词一般只用that, who,即使在强调时间状语和地点状语时也如此,that, who不可省略;强调句中的时态只用两种,一般现在时和一般过去时。原句谓语动词是一般过去时、过去完成时和过去进行时,用it was …… ,其余的时态用it is …… .
    二、not … until … 句型的强调句
    1. 句型为:it is/ was not until + 被强调部分 + that + 其他部分
    e.g. 普通句:he didn"t go to bed until/ till his wife came back.
    强调句:it was not until his wife came back that he went to bed.
    2. 注意:此句型只用until,不用till.但如果不是强调句型,till, until可通用;因为句型中it is/ was not …… 已经是否定句了,that后面的从句要用肯定句,切勿再用否定句了。
    三、谓语动词的强调
    1. it is/ was …… that …… 结构不能强调谓语,如果需要强调谓语时,用助动词do/ does或did.
    e.g. do sit down. 务必请坐。
    he did write to you last week. 上周他确实给你写了信。
    do be careful when you cross the street. 过马路时,务必(千万)要小心啊!
    2. 注意:此种强调只用do/ does和did,没有别的形式;过去时用did,后面的谓语动词用原形。
