英語寫作是英語考試的重要一部分，它佔的分數還蠻重的。熟悉英語句式，可以給你的英語寫作加分，並且可以減少語法錯誤。下面我介紹幾種英語句式結構：
陳述句中有肯定句與否定句之分。其中可以分為以下五種：
①主語+不及物動詞。如：I arrived at six last night.
②主語+及物動詞+賓語，如：I bought a good English Chinese Dictionary yesterday.
③主語+及物動詞+間接賓語+直接賓語，如：Please tell me a story before I go to bed. 這樣可加雙賓語的句子有buy,tell, give, ask, pass, teach.
④主語+及物動詞+賓語+賓語補足語，如：I found it impossible to do it. Please keep the classroom clean and tidy.
⑤主語+系動詞+表語，如：Tom is an American boy. The grass turned green in spring.
在初中常見的句型中有There be…句型，表示存在某種事物，如：There is a map on the wall 其be動詞的形式要與其後面相近的那個名詞相一致。要注意的是這種句型加入助動詞後，也要保持be動詞，不要換用have,如：There is going to be a meeting tomorrow.
在句子結構中要注意主謂一致的問題，即句子的主語與謂語動詞要相呼應。要注意的有如下幾點：
①用and連線兩個主語時一般應視為複數，但如一人身兼兩職時則要用單數謂語動詞形式，如：A singer and dancer is coming to our party. a singer and dancer 既歌唱又可舞的演員。而 a singer and a dancer 則要譯為：一位歌唱家和一位舞蹈家。
②有些以 s 結尾的名詞謂語動詞要用單數，如： The news is good (news為不可數名詞)。
③有量詞時應按量詞的數量計算；如： This pair of glasses is good My glasses are broken.
④有些形單卻意為複數的名詞，如： People are coming here 這樣的詞還有 Police，如果要講一個警察時，應講 a policeman。兩個警察為 two policemen。又如 a policewoman, two policewomen
⑤所有不定代詞 each， either， neither， one， the other， nobody，nothing， anyone， anything， someone， something …要作為單數如： Someone is waiting for you 在並列句中表示聯合關係的連詞有：and not only … but also， neither … nor， either … or 如: My sister and my parents are going to the cinema。表示轉折關係的並列連詞有： but和 yet，如： She is a good student, but she didn't pass the final exam.又如： I think the news is strange, yet it is true 表示選擇關係的連詞有：or， either … or，如： Hurry up, or you will be late for school 表示因果關係的並列連詞有： for， so 如： They studied very hard， so they all passed the exam
賓語從句
①在及物動詞的後面可以接一個名詞來充當賓語，如： I knew the man,而這時也可以用一個句子來充當賓語，如： I knew that he was a good man 這時賓語從句的連線詞有 that, (that 只在從句中起聯接作用，不在句中充當語法成分，既不是主語也不是賓語，所以在口語中常常被省略。如： I am sure (that) she has passed the exam
②if, whether 它們在賓語從句中只起連線作用，不起語法作用，當作是否講。從句中有 or not 結構時，要用 whether, 如： I ask him if (whether) he has had his lunch I asks him whether he has had his lunch or not
③what 它在賓語從句中除了作連線詞外，還要作主語或賓語成份，如： I don't understand what you said (what 作 said 的賓語)。又如： I asked him what made him sick (what 在賓語從句中作主語)。
④who，它也和what一樣，在句中除作連線詞外，可以充當句中的成份，如：I know who she is looking for?
⑤whose 如： I want to know whose book this is?
⑥which 如： Do you know which book is mine?
在連線詞中還有4個常用的連線副詞，
①how 它的應用最廣，如： how much, how many, how long, how soon, how old …。如： How much does it cost?
②when 它只是連線時間狀語，如： Please tell me when the meeting will begin?
③where 它連線地點狀語，如： Where are you from?
④why 它要連線的是原因狀語從句，如： The teacher asked why Tom didn't come to school.
在考試中常見到的考點是：賓語從句的時態與主句時態的呼應問題。①主句謂語動詞如果是現在時或將來時，賓語從句的時態可以是任何所需要的時態，如： I know he didn't come. 我知道他沒來。 I know he will come tomorrow 我知道他明天來。I know he has gone to London 我知道他已去倫敦了。
②主句中的謂語動詞若是過去時，賓語從句也要用過去時態中的某一種。比如：一般過去時，過去進行時，過去將來時，過去完成時。除了在表達宇宙中的客觀真理時，不能用現在時態。如： I wanted to know when he would come The teacher told me the earth moves around the sun
時間狀語從句
其連線詞有：after， before， when， as， as soon as， until (till)，while， since， by 其中較難掌握的有以下幾點
①until (till) 直到，在用 until 表達時間狀語的句子中，主句中的動詞是要十分小心去選擇。如動詞是持續性動詞，它要用肯定句，如： I studied hard until 12 o'clock last night. 如果動詞是瞬間截止性動詞，則要用否定句，如： He didn't go to bed until his mother came back
②由 since， for， by， before 來引導的時間狀語從句。 since 引導的時間狀語是動作的開始時間，如： I have studied English since 1990. 而由 by 引導的時間狀語通常是動作的結束時間，如： I had learned 25 English songs by the end of last term 而before 則多用於完成時， ago則多用於一般過去時，如： He had finished his work before twelve yesterday I left my hometown two years ago
③在狀語從句中用一般現在時或一般過去時表示將來。它們可能是主句用一般將來時，從句用一般現在時，如： If it rains, they won't go to the park on Sunday 也可以主句是一般過去時，從句用一般過去進行時，如： He said if it rained the next day he would not go to the park
④考試中常見的考點有：要學生區別是條件、時間狀語從句還是賓語從句，因在賓語從句中該用什麼時態用什麼時態，如： I want to know if he will come here tomorrow 在賓語從句中的條件狀語從句與主句的關係，如： I want to know if it rains he will come here tomorrow
原因狀語
①because，應譯為"因為"。它表達的因果關係最強，如： He didn't pass the exam because he didn't study hard
②since 應譯為"既然"，如： Since you were ill yesterday I left some notes on your desk
③as 應譯為"由於"，如： As it is too hot we'd better go swimming since與 as 所表達的因果關係遠比 because 弱得多。而 for 表達的因果關係最弱。它不能用於句首，如： He studies hard, for he wants to go to college
比較狀語從句
同級比較 as … as，如： This book is as good as that one 要注意的有兩點：
①as … as 中間要用原級而不是比較級。
②用形容詞還是副詞，如： Mary writes as carefully as Tom 而其否定句為 not as (so) … as，如： They didn't work so hard as we did, 而不同級比較用比較級加 than, 如： He is younger than I am
要注意的是表示"越來越"這一概念時有兩個句型：
①比較級＋and＋比較級，如： The days are getting longer and longer The little girl is becoming more and more beautiful
②定冠詞 the ＋比較級＋ the ＋比較級，如： The harder you study, the more you can learn 方式狀語中要注意的是as (連詞)與 like (介詞)的區別。 as 作為連詞其後接從句，如： Please do it as I did it 但後面的句子常作省略，如： Please do it as I 而 like 是介詞，其後要接的是賓語，如： Please do it like me
結果和目的狀語從句
主要有 so … that， so that， in order that等幾種用法。
① so … that 用在單數可數名詞前，so ＋形容詞＋ a ＋名詞＋ that，如： She is so beautiful a girl that everyone likes her 或用 such ＋ a ＋形容詞＋名詞＋ that, 如： She is such a beautiful girl that everyone likes her
③在不可數名詞或可數名詞複數前只能用 such，如： It is such good weather we want to go for a picnic 又如： They are such good players that they should win the game.
④在much， many， few， little 之前只能用so，如： I have so little money that I can't buy it
⑤so … that 之間只有形容詞時，則不能用 such，如： It is so good that I want to buy
⑥so tha
