a.

He has no friends in this city.
在這個(gè)城市里他沒有朋友.
Palmer有明白的規(guī)定,說在no后接不可數(shù)（uncountable）的事物時(shí),是用單數(shù),并舉例句說I have（or there is）no water（money,bread,hope,difficulty）.所以凡是不可數(shù)的名詞,一概都用單數(shù).成為問題的是那些可數(shù)的名詞（countable noun）,如問句中提出的brother之類.
在“no+名詞”而成為動(dòng)詞have的賓語時(shí),也有種種不同的情形,現(xiàn)分別加以說明如下.
例如一把茶壺普通只有一個(gè)壺蓋,在這種情形下,說“這茶壺沒有壺蓋”時(shí),當(dāng)然是以用單數(shù)為原則：
This teapot has no 1id.
同此類的,都用單數(shù),如：
That cat tias no tail.
He has no fa．ther.
普通一個(gè)人只帶一只手表,出門只帶一架照相機(jī)：
I have no watch.
He has no camera.
至于樹上的葉子必然是很多的,飛螞蟻的翼翅必然是成雙的,人的牙齒也有三十個(gè)以上,所以當(dāng)然都要用復(fù)數(shù)名詞：
That tree has no leaves.
The ant has no wings.
My grandmother has no teeth.
例子：請(qǐng)說明下列三句英語的不同及在no后接名詞時(shí)單復(fù)數(shù)的用法.
(a)I have no brother.
(b)I have no brothers.
(c)I have not a brother.
說到brother這樣的名詞,就很難講了,因?yàn)橛腥酥挥幸粋€(gè)哥哥或一個(gè)弟弟,有人則有好幾個(gè)兄弟,實(shí)在沒有一定,所以問句中的(a)例既可以說,(b)例也可以說,沒有一點(diǎn)什么不同.把no后接的名詞,用作單數(shù)或復(fù)數(shù),全在說話者當(dāng)時(shí)的感觸,如果他覺得對(duì)方只有一個(gè)兄弟他就用單數(shù)名詞,如果他覺得對(duì)方可能兄弟很多他就用復(fù)數(shù)名詞.二者并沒有不同之處,只是反映說話者的意識(shí)而已.再舉同樣情形的例如下：
She has no child(or children).
I have no sister(or sisters).
We have no egg(or eggs)left.
至于(a)及(b)I have no brother(s)與(c)I have not a brother兩句,意思是有些不同的.(a)或(b)句只是說“我無兄弟”,而(c)句則語氣要強(qiáng)得多,可譯成“我連一個(gè)兄弟也沒有”.
There is no(=not any)man who can do it.(普通)
There is not a man who can do it.(強(qiáng)調(diào))
I have no book(s).(普通)
I have not a book.(強(qiáng)調(diào))
There was no egg in the nest.(普通)
There was not an egg in the nest.(強(qiáng)調(diào))
如果不是用在動(dòng)詞have之后,或由there is開頭的旬中,而是用于be動(dòng)詞的場(chǎng)合,意思又不同了.
He is not a teacher．意為“他不是教書的力,他可能是公務(wù)員,也可能是商人等等.
He is no teacher.意為“他不是一個(gè)好教師”,他教書簡(jiǎn)直不成.這句比上句意思強(qiáng)得多.
He is not a poet.(他不是詩人,可能是小說家等.)
He is no poet.(他算不得什么詩人.)
He is not a fool.(他不是一個(gè)笨人.)
He is no fool.(他很聰明.)
It is not a joke.(這不是笑話.)
It is no joke.(這可不是開玩笑的.)
He is not a scholar.(他不是學(xué)者.)
He is no scholar.(他不學(xué)無術(shù).)
I am not a coward.(我非膽怯.)
I am no coward.(我很膽大.)
在there is之后,“no+名詞”的單數(shù)或復(fù)數(shù),和在動(dòng)詞have后的情形一樣,可單可復(fù),例如：
There is no stove in my room．因一間房子中通常只裝一個(gè)爐子,所以用單數(shù).
There are no books on the shelf．因書架上通常要放許多本書,故用復(fù)數(shù).
如果那名詞的數(shù),通常可單可復(fù),則說：
There is no bottle on the table．或
There are no bottles on the table皆可.
在have以外的動(dòng)詞,也可照此原則辦理,例如：
I saw no dog(s).
He wears no tie.
She wears no earrings.
