such 后面如果跟名词,名词一定要是单数吗
举些例子吧

{回答：不一定,请参考以下讲解,望对你有所帮助}
1.such修饰 [单数名词] 时,放于不定冠词a(an)之前,若名词前有one,no,any,some,all, many等修饰时,such放在这些修饰词之后.
He's such a man. 他就是这么一个人.
One such table is enough. 这样的桌子,有一张就够了.
There is no such thing. 没有这么一回事.
2. such位于 [句首] 时,句子须倒装,谓语动词的单复数根据其后的名词决定.
Such is my hope for the future. 我对未来的希望就是这样.
Such were the facts. 事实就是这样.
3.在such…that…,such…as…句型中,如从句不缺少句子成分,用that引导,表示“如此… 以至于”；如从句中缺少句子成分,用as引导,表示“像…
He had such long arms that he could almost touch the ceiling. 他的胳臂很长,几乎能碰到天花板.
She is such a good teacher just as we expect. 正如我们所料,她是一位好老师.
The book is written in such easy English as beginners can understand.
这里的as引导定语从句,替代先行词easy English 在从句中作understand的宾语.
*因先行词前有such修饰,as不可用其他关系词代替.
The book is written in such easy English that beginners can understand it. 这时由that引导结果状语从句,与such构成搭配such…that… 如此……以至于……
★注意：此时that只起到连接词的作用,在从句中不充当成分.
4. 短语：such as表示列举,有“例如、诸如”等意思, as such则是“作为一个…,本身”等意思,
such and such表示“某某,这种那种的”等意思.
1. 表示举例,意为“例如,诸如此类的,像……那样的”,相当于like或for example.如：
There are few poets such as Keats and Shelly. 像济慈和雪莱这样的诗人现在很少了.
*(1) 这类结构既可表现为“名词+such as+例子”,也可表现为“such+名词+as+例子”.如：
I enjoy songs such as this one. = I enjoy such songs as this one.
(2) 若后接动词,通常用动名词,有时也可用动词原形.如：
Don’t do anything silly such as marry him.
Magicians often perform tricks such as pulling a rabbit out of a hat.
(3) 不要按汉语意思将such as用作such like.
(4) 其后不可列出前面所提过的所有东西.如：
I know four languages, such as Japanese and English.
(5) 在现代英语中,such as可与etc. 连用.
They planted many flowers, such as roses, sunflowers,etc. 他们种了许多种花,如玫瑰花、向日葵等.
2. 表示“像……这样的”,其中的 as 用作关系代词,引导定语从句,as 在定语从句中用作主语或宾语.as 不可换成like.如：
He is not such a fool as he looks. 他并不像他看起来那么傻.
3.凡是……的人(或事物)”,相当于 everything that, all those, those that (who)等.其中的 such 为先行词,as 为关系代词.如：
Take such (things) as you need. 你需要什么就拿什么.
You may choose such as you prefer. 你可挑选自己想要的东西.
4. such as 也可引导定语从句.如：
We had hoped to give you a chance such as nobody else ever had. 我们本来希望给你个别人从未有过的机会.
Then I left it,feeling a weight at my heart such as I had never had before. 然后我离开那里,心头感到一种前所未有的沉重心情.
5. Such…as to do sth表示结果,其中的such为限定语,as to do sth 表示结果.如：
It was such a loud noise as to wake everybody in the house. 声音很大,屋里的所有人都被吵醒了.
You shouldn’t put such high prices as to frighten your customers off. 你不应该要价这么高,以致把顾客都吓跑了.
6. such as to do sth,表示程度或结果.其中的such是代词,as to do sth引出的结构作程度状语或结果状语.如：
Her illness was not such as to cause anxiety. 她的病不是很重,不必担心.
The pain in her foot wasn’t such as to stop her walking. 她脚疼,但还不至于不能行走.
7. such as it is “尽管不怎么好”
The food, such as it is, is plentiful. 食物不是很好,但量很多.
You may use my bike, such as it is. 尽管我的自行车不好,你可以将就着用吧.
so as to: 为的是,以便
1. He ran quickly so as to catch the last bus. 他跑得很快以便赶上那末班车.
2. I left a message so as to be sure of contacting her. 我留下了张条子以便与她取得联系.
3. Listen carefully so as to follow the teacher. 要仔细听才能听懂老师讲的课.
4. Please check the list carefully so as to avoid mistakes. 请仔细核对单子以避免发生错误.
such as to: 达到这样的程度以致
1. His speech is such as to incur enmity. 他的演说会引起别人的敌意.
2. Her madness is not such as to fill her mother with despair. 她还没有疯到令其母亲绝望的程度.
