一、句子的重點可以通過下列方法，加以突出：
1. 把重點擺在句首或句尾. 一般而論，最顯眼的位置是在“句尾，其次是在句首，中間的位置最平淡，乏善可陳。例如：
(1)rrect grammar and improper construction invariably distract readers' attention.
(2) The history of vocabulary is, in many ways, the record of civilization.
把重點放在句尾是種“吊胃口”的方法，讀者或聽者非得讀完或聽完整句不可。
2. 在複雜句裡，把主句放在從句之後.除了名詞從句和形容詞從句之外，因為它們位置較固定，副詞從句中有幾種的位置靈活，可以在主句之前出現，也可以跟在主句之後。通常我們就把這樣的副詞從句提前，重點則放在後頭的主句，如：
(3a) I came upon an old classmate when I went to town yesterday.
When I went to town yesterday, I came upon an old classmate.
副詞短語更是如此，如 :
(4a) Steel is commonly used to make knives, razors and other useful tools because of its durability.
Because of its durability, steel is commonly used to make knives, razors and other useful tools.
3. 把較重要或有分量的詞語放在後頭，如和：
(5a) I was delighted and amused by the classical opera
I was amused and delighted by the classical opera.
(6a) That singer's life was tragic and brief.
That singer's life was brief and tragic.轉載自:考試大 - []
4. 把句子中一系列的專案作邏輯性的排列。例如：
(7) Tony ate his dinner, watched TV, and then went to bed.
(8) Were you bored with years of study in elementary school, high school and institute of higher education?
5. 必要時，重複重要的語詞或概念。 例如：
(9) Jackie enjoys the company of ladies. He likes their beauty, he likes their delicacy, he likes their vivacity, and he likes their silence.
(10) land stretched out without names. Nameless headlands split the surf; nameless lakes reflected the nameless mountains and nameless rivers flowed through nameless valleys and nameless bays.
6. 儘量用主動語態，因此比(11a)好：
(11a) A pedestrian was struck on the head by a flying stone.
A flying stone struck a pedestrian on the head.
7. 適當時候，可用倒裝句和平行句，如：
(12) Seven dwarfs lived here in the center of the dark forest. →
Here, in the center of the dark forest lived seven dwarfs.
(13) Severity breeds fear; roughness breeds hatred.
(14) Honesty recommends that I speak; self-interest demands that I remain silent.
二、it作句子的真正主語
指前面已經提到過的人或事物，有時指心目中的或成為問題的人或事物，作真正主語。
例如： What’s this? 這是什麼?
-It is a sheep? 這是一隻綿羊。
Who is it? 誰?
-It's me. 是我。
It’s the wind shaking the window. 是風颳得窗戶響。
指時間、季節
一般用在無人稱動詞的主語。
例如： What time is it? -It’s nine.
幾點了?九點了。
It’s time for the meeting. Let’s go.
開會的時間到了，我們走吧。
What day is today? -It’s Saturday. 今天星期幾?今天星期六。
What’s the date today? -It is October 1st. 今天是幾號? 今天是十月一日。
What season is it? -It is summer. 現在是什麼季節?是夏季
指氣候
一般作無人稱動詞的'主語。
例如： Is it cold in this room? -No, it isn’t. 屋裡冷嗎?不冷。
What’s the weather like today? -It is fine. 今天天氣怎麼樣?是晴天。
It often rains in summer and it often snows in winter in this city.
這個城市夏天經常下雨，冬天經常下雪。
指距離、情況等
一般用作無人稱動詞的主語。
例如： It is five kilometers from my home to the school. 從我家到學校有五公里。
It is very near from this factory to that one. 從這個工廠到那個工廠非常近。
It is a long way to the sea. 離海很遠。
Is it well with you? 你身體好嗎?
三、it作形式主語
動詞不定式、動名詞短語、從句在句子中起主語作用，而這一部分用詞較多時，可以用it作為形式主語，放在句首代表其後所說的事實上的、真正的主語，而把真正的主語放在後面。
+謂語+動詞不定式。It 作形式主語，動詞不定式作真正的主語。
例如： It is difficult to climb a mountain. 爬山是很艱難的。
It’s a good habit to do morning exercises. 作早操是個好習慣。
It’s important to do proper memory work in the study of a foreign language.
在學習外語時適當地做一些有助於記憶的練習是很重要的。
It is right to do so. 這樣做是對的。
+謂語+動名詞短語
It 作形式主語動名詞短語作真正的主語。
