這篇關(guān)于2013小學四年級英語語法輔導(dǎo)：用助動詞進行強調(diào)，是特地為大家整理的，希望對大家有所幫助！
    強調(diào)句還有一種類型，就是用助動詞do (did，does) 強調(diào)謂語。
    She does like this horse.　她的確喜歡這匹馬。
    Please do take care of yourself. 千萬保重。
    ?？嫉膹娬{(diào)句結(jié)構(gòu)是it 引導(dǎo)的句子。
    It is (was) 被強調(diào)部分+ that (who) + 句子其他部分。
    此結(jié)構(gòu)強調(diào)的成分僅限于主語，賓語和狀語。
    It is from the sun that we get light and heat.
    It was not until I had read your letter that I understood the true state of affairs.
    典型例題
    1) It was last night ___ I see the comet.
    A.　the time　B.　when　 C.　that　　D.　which
    答案C. 強調(diào)句的結(jié)構(gòu)是： It +be +強調(diào)部分 + that (who) + 主謂句?！娬{(diào)句的連詞只有兩個，that和who。當強調(diào)的部分是人，且為句子的主語時，才用 "who"，其余用that。
    原句：　My father did the experiment in the lab yesterday evening.
    強調(diào)主語： It was my father who did the experiment in the lab yesterday evening.
    強調(diào)賓語： It was the experiment that my father did in the lab yesterday evening.
    強調(diào)時間： It was yesterday evening that my father did the experiment in the lab. (注意不用when)
    強調(diào)地點： It was in the lab that my father did the experiment yesterday evening.
    2)It is ten years ___ Miss Green returned to Canada.
    A. that　B. when　 C. since　 D. as
    答案C. 考點是連詞用法。 本題易誤選為A. that. 其實本句不是強調(diào)句。若是，去掉It　 be… that還應(yīng)是一個完整的句子。而本句去掉 'It is…that'，只剩下ten years Miss Green returned to Canada. 不成句。因此本句不是強調(diào)句。
    It is /was +時間+ since…　其中is<---> has been　 was <---> had been.
