Can you imagine how late I went to bed last night?It was nearly(that/when/before/ as) I finshed my artical.答案是when,重点求解释为什么不选that

句子意思为， 接近我完成文章（我才睡觉） 强调时间，用when
再问： 打错了 ...nearly 后少打了1am.
再答： 懂了吗？ 可否打赏个财富值呢？嘻嘻^v^
再答： 1am是下午一点，强调时间用when不可用that
再答： 若是that则少个先行词奥～
再问： 这个句子为什么不能是强调句呢？
再答： 强调句that后应是完整的句子
再问： 还是说nearly1AM不能独立做状语
再问： ？
再问： 你的回答完美的解决了我的问题，谢谢！
再答： 时间状语
再问： 是说不可以吗？
再答： 可以
再答： 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。
