一、就近一致原則
1.由or，not only...but also...，neither...nor...，either...or...，whether...or...，not...but...等連接兩個或兩個以上的并列主語時，通常根據就近一致原則，謂語動詞要與離它最近的主語在數上保持一致。
Neither his parents nor I am able to persuade him to change his mind.
2.here/there引導一個句子而主語又不止一個時，通常根據就近原則，謂語動詞要與離它最近的主語在數上保持一致。
Here is a ruler，a few pencils and two copybooks.
二、意義一致原則
1.謂語動詞必須用單數的情況
(1)表示學科的名詞以及works(工廠)，news(消息)等作主語時，雖然本身為復數形式，但表示單數意義時，謂語動詞仍用單數。
Politics is his favorite subject.
(2)表示某些組織機構的名詞、書/報名、國名、地名等作主語時，雖然形式上是復數，但所表示的意義是單數，所以謂語動詞用單數。
Do you know when the United Nations was set up?
2.謂語動詞必須用復數的情況
表示總稱意義的名詞，如people，police，public，cattle等作主語時，謂語動詞用復數。
The police are searching for the murderer.
3.謂語動詞的形式依據主語表示的意義而定
(1)集體名詞，如family，class，group，team，club，company，government，population等作主語時，謂語動詞的形式根據其在語境中表示的意義而定。當其表示集體意義，強調整體概念時，謂語動詞用單數;當其表示集體中各個組成部分，強調個體概念時，謂語動詞用復數。
As far as I know，his family is not very large but the family are all music lovers.
(2)“the+形容詞/分詞”表示“一類人”時，謂語動詞用復數。
The poor were looked down upon in the old days.
三、語法一致原則
1.由and連接的兩個名詞作主語
(1)“a/the+名詞單數+and+名詞單數”表示一個人(雙重身份)，謂語動詞用單數。
The teacher and poet often gives lectures around the city.
(2)“a/the+名詞單數+and+a/the+名詞單數”表示兩個人，謂語動詞用復數。
The teacher and the poet have just arrived.
(3)“every+名詞單數+and+every+名詞單數”表示每一個人，謂語動詞用單數。
Every boy and every girl has the right to receive education in our country.
(4)通常由兩個部件組成的物品如：a knife and fork (一副刀叉)等作主語，謂語動詞用單數。
Bread and butter is not to his taste.
2.表示時間、數量、長度及價格的名詞，盡管有時是復數形式但常被看作是一個整體，謂語動詞用單數形式。
Is fifty pounds enough?
3.“分數/百分數+of+名詞”作主語時，謂語動詞的形式根據of后的名詞的形式來定，如果名詞是可數名詞復數，謂語動詞用復數形式;如果名詞是單數可數名詞或不可數名詞，謂語動詞用單數形式。
Two-thirds of the books are about science.
Only 30% of the work was done yesterday.

1. 定義：用作主語的從句叫做主語從句。
2. 構成：關聯詞+簡單句
3. 引導主語從句的關聯詞有三類：
(1) 從屬連詞that。 如：That they were in truth sisters was clear from the facial resemblance between them.
很明顯，她們確是親姐妹，她們的臉型很相似。
(2) 從屬連詞whether。如：
Whether he’ll come here isn’t clear. 他是否會來這里還不清楚。
(3) 連接代詞who, whom, whose, what, which, whoever, whatever, whichever
連接副詞 where, when, how, why。如：
What she did is not yet known. 她干了什么尚不清楚。
How this happened is not clear to anyone. 這事怎樣發生的，誰也不清楚。
Whoever comes is welcome. 不論誰來都歡迎。
Wherever you are is my home ---- my only home. 你所在的任何地方就是我的家----我的家。
解釋：
1. 主語從句能用it作形式上的主語。常以it作形式主語的句型有：
A. It+be+形容詞(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that從句。如：
It is certain that she will do well in her exam. 毫無疑問她考試成績會很好。
It is probable that he told her everything. 很可能他把一切都告訴她了。
B. It+be+名詞詞組(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that從句。如：
It’s a pity that we can’t go. 很遺憾我們不能去。
It’s no surprise that our team should have won the game. 我們沒贏這場比賽真意外。
C. It+be+過去分詞(said, reported, thought, expected, decided, announced, arranged, etc.)+that從句。如：
It is said that Mr. Green has arrived in Beijing. 據說格林先生已經到了北京。
It is reported that China has sent another man-made earth satellite into orbit.
據報道中國又成功地發射了一顆人造地球衛星。
D. It+seem, happen等不及物動詞及短語+that從句。如：
It seems that Alice is not coming to the party at all. Alice似乎不來參加晚會。
It happened that I was out that day. 碰巧我那天外出了。
E. It+doesn’t matter (makes no difference, etc.)+連接代詞或連接副詞引起的主語從句。如：
It doesn’t matter whether she will come or not. 她是否來這無關緊要。
It makes no difference where we shall have the meeting. 我們在哪里開會毫無區別。
F. 當that引導的主語從句出現在疑問句中時，要以it作形式主語，而把主語從句后置。如：
Is it true that the scientist will give us a lecture next week? 下周那位科學家將給我們作報告是真的嗎?
Does it matter much that they will not come tomorrow? 他們明天不來很要緊嗎?
G. 當主語從句出現在感嘆句中時，要以it作形式主語，而把主語從句后置。如：
How strange it is that the children are so quiet! 孩子們這么安靜真奇怪!
2.注意連接代詞whoever, whatever, whichever等引導主語從句的含義
Whoever comes will be welcome. (whoever=the person who) 來的人將受到歡迎。
Whatever he did was right. (whatever=the thing that) 他所做的事情是正確的。
Whichever of you comes in will receive a prize. (whichever=anyone of you who) 你們當中不論哪個進來將會得到獎
