英語it強調句與其他it句子的區別
強調句結構 常考的強調句結構是it 引導的句子. It is (was) 被強調部分+ that (who) + 句子其他部分. 此結構強調的成分僅限于主語，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. 強調句的結構是： It +be +強調部分 + that (who) + 主謂句. 強調句的連詞只有兩個，that和who.當強調的部分是人，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. 強調主語： It was my father who did the experiment in the lab yesterday evening. 強調賓語： It was the experiment that my father did in the lab yesterday evening. 強調時間： It was yesterday evening that my father did the experiment in the lab. （注意不用when） 強調地點： 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. 其實本句不是強調句.若是，去掉It be… that還應是一個完整的句子.而本句去掉 'It is…that'，只剩下ten years Miss Green returned to Canada. 不成句.因此本句不是強調句. It is /was +時間+ since… 其中is has been was had *的強調句只有這些其他的IT 可以做形式上的主語 但不是強調句。
看看這個英語句子造得正確與否It'
基本上是對的，不過一般說in the morning.時態的話我覺得用過去時（recited）或現在完成時（have recited）或現在進行時（am reciting）都說得過去對于it's the first time that。
這個句型，意思根據時態有細微的差別.加上"在中學時"的話我覺得用過去時比較好.It's the first time that I recited English words in the morning at home in the junior high school 這個句子是不對 是in the morning你要強調的是你在某個時間做第一次事情.在中學時加上去的話就要變成過去時.The first time i recited english words was in the morning at home in the high school.我第一次背誦英語單詞是在家里的一個早上，那時候在上中學.。
英語句子分析“It'salsoenvironmentallyfriendly.”全句是：
在北京，公共汽車為人們的出行帶來了很大的便利，并且它還很環保.Environmentally 是副詞，Friendly 是形容詞.environmentally修飾friendly，這個沒錯！friendly就是用來說 buses 的啊.單看后面這句話，去掉also,environmentally這樣的修飾的成分，句子主干就變成了 It is friendly！這樣的句式就好比 you are beautiful .I am cold 一樣.（ Environmentally friendly就是【環保的】的意思，這個屬于一種搭配，根據句意，是不能拆開的，否則就不符合句子想表達的意思了，我之所以把句子拆開，提出主干，是為了方便你理解.）歡迎追加.。
