5. Not a chance. 一点机会也没有.
这句话根 "You don't have any chance" 是一样的, 都是表示根本就没有机会. 例如比赛前别人问你, "Can we beat them?" 你就可以说, "Not a chance"
跟 Not a chance 意思相当的句子有很多, 例如 "Not really", "Not in a million years", "Not in my life time" 或是 "Not in your life time" 例如你要跟朋友去打球, 你朋友说, "You man. I'm gonna kick your ass!" 你就可以说, "In your dream, pal! Not in your life time" 意思就是, 作你的大头梦去吧! 我看在你的有生之年是不可能了!
6. Not at all. 一点也不.
这句话通常是用来回答别人的问题, 例如别人问你, "Do you like American food?" 你就可以回答 "Not at all". 这句话强调出一点也不喜欢. 如果只说 "No, I don't like it." 可能多少还会吃一点, 可是 "Not at all" 可能就是连吃都不会想去吃了, 算是全部否定对方的回答.
如果是部份否定的话, 你可以说 "Not really" 表示你不全然同意对方所说的话. 像是同样如果别人问你, "Do you like American food?" 你说 "Not really." 就表示出你不是那么喜欢.
7. Not good enough. 还不够好.
这句话是专门用来挑剔别人用的. 例如小孩考了八十分就很兴奋地跑去跟父母说, "I got 80 in the test!" 他父母如果是那种比较严苛一点的人的话, 可能就会说, "Not good enough." 或是你也可以泼别人冷水, 例如别人说, "That book is awesome!" 你就可以回他一句, "Not good enough for me."
8.Not again 不会再来一次吧.
当有什么倒霉事第一次发生时, 你可以笑笑地说 bad luck 或是 rotten luck. 但是当第二次又接著发生了, 你大概就会说, "No, not again" 例如车子爆胎了, 你刚拿去补完才出汽车修理店门口又被一根铁钉刺到, 我想任何正常人的反应一定都是 No, not again 吧!
9. Not possible. 不可能.
这个 not possible 跟 impossible 是一样的意思. 可是就算有了 impossible 这个字, 很多老美还是喜欢说 not possible. 可能是这个 not 比较能强较出 "不"的意思吧! 例如有人问你可不可以在半小时内到某地会面, 你就可以说, "Not possible, it's rush hour now."
10. Not a soul in sight. 半个人影也没有.
这句话算是固定的用法. Soul 在这里就是指人而言. 如果讲的不是人而是其它的东西的话, 则用 "Not a thing." 例如别人问你, "Did you see anything in the bush?" 要是你什么也没看到, 你就可以回答, "Not a thing."
 
表示“正在进行”的be＋介词短语
表示“正在进行”这一动作，通常用现在进行时表示。如：I am having a class now．（我正在上课。）但“正在进行”这一动作，还可以用“be＋介词短语”来表示。常见的介词短语类型有： be ＋at引导的介词短语；be ＋in引导的介词短语；be ＋on引导的介词短语； be ＋under引导的介词短语等。

值得英语学习者注意的是
⑴尽管be＋介词短语能表示“正在进行”这一意义，但它和be＋现在分词所表示的语法意义是有差别的。前者着重事物所处的状态，偏重于静态；后者着重事物的动态，集中表示事物的动感。
⑵绝大部分这类结构，其名词前都没有冠词，假如加一冠词，意义将大相径庭。如：The Conservative Party is in office．保守党在执政。The principal is now in the office．校长现在在办公室。英语学习者对上述差别决不可掉以轻心。
 
★起形容词作用的分词（形容词型分词）★
记得前两天有旺友问“动词+ed"作形容词的问题，刚好张道真的一本语法书上有很详细的介绍，准备把它拿到这和大家共享。有点长，而我打字又慢，慢慢输吧，争取在7-10天内完成：）
起形容词作用的分词（形容词型分词）
a. 分词作定语的用法
1)总的特点
分词可以作定语，修饰或是限制一个名词，可以放在它前面，也可以放在它后面。一般说来，简单分词可以放在名词前面，分词短语放在名词后面。
a)放在名词前面的分词
1/表示动作的分词：
一个现在分词或过去分词放在名词前时，可以表示一时的动作，这时它的动词特点胜过形容词特点，相当于一个定语从句
Do you see the rising sun(=sun which is rising) in the east?
They tried to surround the retreating troops (=troops which were retreating).
The roaring lion frightened all the animals in the jungle.
They tried to deliver the besieged city (=city which was being besieged).
These repeated efforts(=efforts which were being repeated) were still inadequate.
Those oppressed nations (=nations that are being oppressed ) are rising to liberate themselves.
2/表示特点的分词：
它也可以表示比较长久或永久性的特点。这时它的形容词特点胜过它的动词特点：
Germs are living creatures (=not inanimate things, creatures that can live).
She is a charming lady (attractive lady, lady who charms others)
The working classes are usually poor.
There were many flying fish.
We watched the moving pictures (=motion pictures)
Used cars (=old cars,cars which have been used) are cheaper than new ones/
Stolen love (=Secret love, love which is stolen), though dangerous, tastes exceptionally sweet.
This printed matter may be sent by mail.
3/和用作形容词的动名词的差别：
用在名词前的现在分词和用在名词前起形容词作用的动名词是有区别的，从意思上、重音上及是否加连字号，都有区别。下面各对句子中，第一句中带-ing词尾的动词为分词，第二句中带-ing词尾的动词为动名词：
Boiling water(=Water that is boiling) can produce enormous power.
Water begins to boil at the boiling-point(=point at which liquid boils;而不是point which boils).
He is a walking dictionary (=dictionary that canwalk, learned man).
He came with a walking-stick (=stick for walking;非stick that os walking)
How clever that dancing bear (=bear that is dancing) is!
He is a dancing-master (=master who teaches dancing).
Someone said many years ago thatChinawas a sleeping lion (=lion that was sleeping).
He is in the sleeping-car (=car for sleeping,而不是 car that is sleeping).
Running water is cleaner than stagnant water.
It is a running-track for sportsmen.
4/用作名词的情况
和形容词一样，某些分词在加the时（后面不跟名词），可以代表一类人或一种抽象东西：
Which are more numerous, the dead or the living (=the living people)
Something must be done immediately with the wounded and the dying.
What should we do with the oppressed, the defeated the insulted and the injured?
Can we say anything about the unseen (=the thing unseen) and the unknown (=the thing unknown)?
放在名词后的分词
放在名词后的分词多数是分词短语，它可以变成一个定语从句（尽管定语从句不一定都能变成分词短语）：
1/表示一时动作的分词短语：
The danger threatening the world (=which is threatening the area ) is too many people with too little food.
They looked on at the city being attacked by the enemy (=which was being attacked by the enemy).
The man being followed by guards (=who are being followed by guards) is a party leader.
2/表示长久特点的分词短语：
A man respecting others (=who respects others ) will be respected.
Can you teach a boy refusing to be taught (=who refuses to be taught)?
It is difficult to save a man enchanted by the beauty of a woman.
Books called the comics (=that are called the comics ) are sometimes harmful to children.
Any books well read (=that are well read ) are good books and any men well treated are good men.
名词前作定语的分词
a)用在名词前的不及物现在分词
