一九.so與such區別：so是副詞，后跟形容詞/副詞，so tall/slowly…

such是形容詞，后跟名詞短語。such bad weather / good news…;

such a beautiful girl / an important lesson / a heavy stone…;

such kind boys / new desks / friendly people / amazing movies…;

若名詞前形容詞是many, much, few, little時，不用such, 而用so.

so many flowers / much rain / few friends / little water…

也常有“so / such …that…”句型，譯為“如此…以致于…”。

二○.so的另兩個用法：1so + be/情態動詞/助動詞+主語，“…也”

上下文所指不是同一個人或物。The twins are working, so am I.

I will stay up tonight, and so will Peter.

以及對話形式：A: I woke up late this morning. B: So did I.

2so + 主語 + be/情態動詞/助動詞，“的確…是”上下文所指是同一個人或物。A: We have lunch at school. B:

二一.the number of / a number of: 前者“…的數量”；后者“許多的”

都跟可數名詞復數。前者作主語，謂語用單數；后者作主語，謂語用復數。The number of the trees is two thousand. 用單數is.

A number of trees have been cut down.用復數have.

40.延續性動詞：How long，since，for，(以上見84）until/till等所在肯定句中的主句謂語要用延續性動詞。

3Both of the twins are clever. 后面謂語用復數。

4None of the students has/have been there before.

none +of +限定詞+復數, 謂語用單、復數都可。另見88

6-When shall we meet, Saturday or Sunday?

二四.hundred/thousand/million/billion: 前有具體數字，不加s及of. 否則加s, 加of. 如：thousands of trees; many millions of people.

nine hundred people, ten thousand students等。但前若有several,后常不加s和of：several million pounds

二五.反意疑問句(QT)部分用法:1something, nothing, anything, everything作主語，QT主語用it.

Something is wrong, isn’t it? / Nothing is difficult, is it?

2I think Lucy can do well in the exam, can’t she?

>

I don’t think he will 買粉絲e here on time, will he?

QT要結合think后的從句而定。

3祈使句的QT一般用will you? 而Let’s …用shall we?

Get up now, will you? Don’t be noisy, will you?

Be quiet, will you? Please don’t talk, will you?

Let us do it now, will you? Let’s do it now, shall we?

4There be句型，QT主語用there.

There is a man working in the field, isn’tthere?

There used to be a meeting on Friday, didn’tthere?

There won’t be a movie in the theatre, willthere?

二六.虛擬語氣部分用法：在非真實條件句中要用虛擬語氣，即if 從句中用一般過去時，而主句動詞用would/should+動詞原形，表示與現在相反的主觀設想，也可以表示在說話人看來實現的可能性很小的情況。（注意：虛擬語氣中的be動詞都要用were.）

If there were no air, people would die. (與現在事實相反)

Mrs. Green has two sons, one is interested in math, the other (one / son) is good at science. 又如：This pair of shoes is strange. One is blue, yet the other is green. 這雙鞋子很怪，一只藍色，而另一只綠色。

第二種，只有兩部分：此種 情況下the other后接可數名詞復數，或不接名詞而只在the other后加s. Two fifths of the students in our class are boys, the other students are girls / the others are girls. Two children went, but the others stayed. （其他孩子都留下了。）

3如果沒有顯示出只有兩部分，未給出范圍，則是泛指，不加the.

Lei Feng liked helping other people / others.

Have you any other questions?

Alice didn’t like that dress, so she asked to see some others.

4other的另一用法：用比較級的形式，體現最高級的含義。

He is taller than any other boy in his class. (劃線中boy用單數) =

He is taller than all the other boys in his class. (劃線中boy用復數)

他比班里任何男孩都高（他是班里男孩中最高的）。
