【導語】英語語法讓很多學生都頭疼，因爲複雜難懂的句式和詞組有時難以記憶。爲大家整理了英語語法大全，希望對同學們的英語語法學習有所幫助。更多內容盡在。
我們在說話、寫文章的過程中，爲了要突出句子中的某一部分時，就常使用某種方法、手段使它突出，以便能引起他人的注意，這就是強調。
英語中，表示強調的方法一般分爲三種：位置的強調;用詞強調;句型強調。如：
一、位置強調
英語句子的語序，一般爲：主、謂、賓、表、狀。有時爲了強調某個成份，就故意將它移到句首或句末。如：
A.強調主語及狀語。如：
(1) I was reading English this morning. — This morning, I was reading English. 今天早晨，我一直在讀英語。
(2) I’ll go to see Li Lei tomorrow. — Tomorrow, I’ll go to see Li Lei. 明天，我要去看李蕾。
B. 強調謂語(as, though引導的讓步狀語從句)
(1) Though he will try, he can’t succeed. — Try as / though he will, he can’t succeed. 儘管他會嘗試，但他不會成功。
(2) Though she can sing, she can’t sing well. — Sing though / as she can, she can’t sing well. 儘管她會唱，但唱得不好。
C. 強調賓語或表語(as, though引導的讓步狀語從句)
(1) Though he learnt English, he didn’t learn it well. — English as / though he learnt, he didn’t learn it well. 儘管他學過英語，但他學得並不好。
(2) Though he is ill, he keeps on working. —Ill as / though he is, he keeps on working. 儘管他有病，他仍堅持工作。
二、用詞強調
英語中強調的另一種方法，就是用不同的詞進行誇張從而達到強調的目的。用詞強調主要有以下幾種形式。
A. 在句子中的謂語動詞前加助動詞do, 對謂語進行強調。如：
(1) I do like swimming. 我的確喜歡游泳。
(2) He did go there last night. 他昨天晚上的確去過那兒。
B. 用awfully, badly, dead, deeply, ever, extremely, highly, indeed, lightly, not…at all, particularly, pretty, really, so, strongly, terribly, utterly, very, very much,等副詞修飾以加強語氣。如：
(1) He wants to get it very much. 他非常像得到它。
(2) I miss you terribly. 我非常思念你。
C. 用短語at all, on earth, in the world, under the sun等表示強調，意思是：到底，究竟，根本。如：
(1) I don’t know it at all. 我一點也不知道。
(2) What on earth are you doing there? 你到底在那幹什麼?
4) 用重複某一個詞或短語來強調。如：
(1) He thought and thought, and suddenly he got a good idea. 他想啊想啊，突然想到了一個好主意。
(2) He ran and ran, and at last he caught up with other students. 他跑啊跑啊，終於趕上了其他的同學們。
三、用句子來強調
英語中最常見的強調手段，也是我們必須要掌握的`方法就是句型強調，即：強調句型。It is / was + 被強調的部分 + that (who)…如：
(1) It was in the room that Li Lei was born. 李蕾出生就在這間房子。
(2) It is Wei Fang who has broken the record. 就是魏方打破了紀錄。
B.在使用強調句型時須注意的幾個問題：
(A) 原句子是現在時或將來時，強調句用It is + 被強調的部分 + that (who)…; 若原句子是過去時，強調句用：It was + 被強調的部分 + that (who)…
(1) Li Lei’s father will work in America. —It is in America that Li Lei’s father will work. 李蕾的父親的工作將就在美國。
(2) I studied at this school a few years ago. —It was at this school that I studied a few years ago. 幾年前我就在這所學校讀書。
(B) 即使被強調的部分是複數，It後面始終用單數形式。如
(1) Tom and Lucy gave us much help. —It was Tom and Lucy that gave us much help. 正是湯姆和露西給了我們很多的幫助。
(2) I saw swans in the lake yesterday. —It was swans that I saw in the lake yesterday. 昨天我看到在湖裏的就是天鵝。
(C) 強調人時，可用who 代替that, 但若強調時間、地點、原因、方式時，不能用when, where, why, how代替 that。如：
(1) It is our teacher who / that helps us make great progress. 正是我們的老師幫助我們取得了很大的進步。
(2) It is by bus that I go to school every day. 每天我就是乘公共汽車上學。
(D) 在強調not…until結構中的時間狀語時，應將not移到until前，再將not until部分移到被強調的位置。如：
I didn’t go to bed until twelve o’clock last night. — It was not until twelve o’clock last night that I went to bed. 昨天晚上我一直到十二點才睡。
(E) 強調一般疑問句中的某一成分時，將強調句中的主句用一般疑問語序。如：
(1) Do you like English?—It is English that you like? 英語就是你喜歡的嗎?
(2) Will you go to London?—It is London that you will go to? 你要去的就是倫敦嗎?
(F)特殊疑問句中只有疑問詞可以被強調。句型爲：特殊疑問詞+be + it that+…? 如：
(1) What made him so angry?—What is it that made him so angry? 是什麼東西使他如此生氣?
(2) Why did she cry?—Why was it that she cried? 是什麼原因使他哭了起來?
(G) 強調主語時，who 或that後面的謂語形式須與被強調的主語保持一致。如：
(1) Lily speaks Chinese very well. —It is Lily who / that speaks Chinese very well. 李麗的漢語講得很好。
(2) Children like stories. —It is Children that like stories. 孩子們喜歡故事。
(H) 強調句中的be前可用表推測的情態動詞：must, can, may等。如：
(1) It must be Piney that sent us this present. 肯定是Piney 給我們寄來了這件禮物。
(2) How can it be that he didn’t pass the exams. 他考試沒有通過怎麼可能呢?
(I) 強調句型不用於強調謂語、表語、since, as等引導的原因狀語從句。如：
He is better today since he can walk around without my help. 就不能有下列強調形式：
It is better today that he is today since he can walk around without my help. (錯)
It is since he can walk around without my help that he is better today. (錯)
