i think it my duty to help her.（＝it is thought my duty...）
6）.用于強調(diào)句型中it is（was）＋被強調(diào)部分（主語、賓語或狀語）＋that（who）...。it無任何指代關(guān)系，也無實義。
it was john who（that）wore his best suit to the dance last night.
it was in shanghai that i first met jack.
強調(diào)結(jié)構(gòu)的8個易錯點
一、關(guān)于結(jié)構(gòu)中的that
此結(jié)構(gòu)中，除強調(diào)的是作主語或賓語的人時可以用who外，其它任何情況都只能用that。如：
it was kate that/who told me about it. 是凱特告訴那件事的。
it was yesterday afternoon that she told me about it. 是昨天下午她把那件事告訴我的。(that不能用when替代)
二、關(guān)于結(jié)構(gòu)中be的形式
原句中謂語動詞是過去式，強調(diào)結(jié)構(gòu)的be用is，原句謂語動詞是現(xiàn)在時或?qū)頃r，強調(diào)結(jié)構(gòu)的be用was。如：
it is he that likes playing games. 是他喜歡打游戲。
it is tomorrow that we will have a meeting. 是明天我們要開會。
注：be有時與表示推測的情態(tài)動詞連用。如：
it must be john that/who cleaned the room. 一定是約翰打掃房間的。
三、關(guān)于主謂一致問題
被強調(diào)的是原句的主語時，要注意that/who后的謂語動詞與原句主語一致。如：
it is i that am in trouble. 是我陷入了困境。
it is you that are wrong. 是你錯了。
四、強調(diào)結(jié)構(gòu)的省略式
—who is making so much noise in the garden? 誰在花園里吵鬧？
—it is the children. 就是那些小孩呀。(=it is the children that are making so much noise in the garden. )
五、如何強調(diào)否定句
要將not一同強調(diào)，構(gòu)成it is/was not…that…
it is not he that/who studies french. 學法語的不是他。(原句：he doesn’t study french. )
六、如何強調(diào)雙賓語
無論強調(diào)哪個賓語，都必須根據(jù)動詞的搭配關(guān)系，加上to或for。如：
原句：he gave mary a pen.
強調(diào)直接賓語：it was mary that he gave a pen to.
強調(diào)間接賓語：it was a pen that he gave to mary.
七、強調(diào)結(jié)構(gòu)作賓語時的語序
要與陳述句語序相同。如：
i don’t know where it is that he has gone. 我不知道他去哪里了。
八、強調(diào)結(jié)構(gòu)與類似句型的區(qū)別
判斷是否是強調(diào)結(jié)構(gòu)的方法是：去掉it is/was和that后，剩余部分(經(jīng)調(diào)整后) 是否依然是個完整的句子，若是，就是強調(diào)結(jié)構(gòu)，否則就不是。
it is a pity that you could not come. 真遺憾，你不能來。(去掉it is和that后，句子不成立，是形式主語句型)
it was at ten that he got home. 他是十點回到家的。(去掉it was和that后，原句可調(diào)整為he got home at ten. 句子完整正確，故這是強調(diào)結(jié)構(gòu))
7）.it 短語
make it ①成功,做到,趕上 ②約定:let’s make it next week
as it is ①用于句前表 “事實上” ②用于句末, “照原樣”
leave the chair as it is. 讓這椅子照原樣放著.
as it were 可以說,在某種程度上.he is, as it were, a walking dictionary
see to it that 注意,留神, 負責 see to it that everything is ready.
四、it常考察句型
1. it is + 被強調(diào)部分 + that ... 如果把這種句型結(jié)構(gòu)劃掉后，應(yīng)該是一個完整無缺的句子。這也是判斷強調(diào)句型與其它從句的方法。
