部分否定(不完全否定)的幾種方法
一、all的否定形式： not all……(all ……not)並非都……(不是所有的都)
not all men can be masters. = all men cannot be masters.並非人人都能當頭頭。
not all bamboo grows tall.並非所有竹子都會長得很高
二、both的否定形式：not……both或both……not 並非兩個……都……
i don’t want both the books我並不是兩本書都要。
both (the) windows are not open.兩扇窗並不是都開著。
三、every的否定形式：不是每……都
not every book is educative. = every book is not educative.不是每本書都有教育意義。
not everyone likes this book。並非人人都喜歡這本書。
this flower is not seen everywhere. 這花並非隨處可見。
四、always的否定形式：並非總是(並非一直……)
he is not always so sad .他並非一直都這樣悲傷。
五、entirely、altogether、comply、quite的否定形式：不完全……並非完全
the busineman is never to be trusted.不可以完全信任商人。
he felt not altogether satisfied.他不完全滿意。
i don’t agree completely。我不完全同意。
what he did was not quiet proper.他做得不十分妥當。
六、all the time ……並非一直/未必老是
a foolish man doesn’t make a mistake all the time.笨人並不是老是犯錯誤
七、not……and的否定形式：往往是否定and後面的部分
he did not speak clearly and correctly。他講得清楚但不正確
this film is not interesting and instructive.這部電影有趣但沒有教育意義。
she can not sing and dance. 她會唱歌但不會跳舞。
and如果換成or，not對其後面的部分完全否定
he did not speak clearly or correctly.他講得極不清楚又不正確。
如果上述的all、both、always以及entirely、altogether、completely、quite和all the time等詞作完全否定，那就要分別用於之相對應的完全否定詞，如no 、none、nether、no one 、never、not(never)……at all等。
all of them can do it. —— none of them an do it.
both are good.—— nether is good.
everybody likes it.—— nobody likes it.
he is always late.—— he is never late.
he was here all the time.—— he was never here.
It's very kind of you.
How nice of you.
Thanks a lot.
Thanks very much.
在日常對話中，一提起“感謝”或“感激”，我們通常會想到最常用的英語單詞“thank”。學過英語的`人都會說類似的感謝語，如Thanks，Thanks a lot，Thank you very much，Thank you for your help等。其實，在英文信函往來或對外交流中，除了thank以外，還比較經常使用appreciate這個詞來表示感謝。下面是一些常見的例句：
1、We appreciate your efforts for the development of the company.
我們感謝你對公司發展所作的努力。
2、We greatly appreciate your timely help.
我們非常感謝你們及時的幫助。
3、I'd appreciate it if you would turn the TV down.
請你把電視機的音量調低一些。
4、I appreciate your telling me the truth.
感謝你告訴我真-相。
值得注意的是，appreciate是及物動詞，當它表示“感謝”時，它的賓語通常是人做的事，而並不是人本身，這一點與中文表達習慣完全不同。所以，我們不可以說I would be much appreciated if you could send me the reply as soon as possible. 而應該說成It would be much appreciated if you could send me the reply as soon as possible. 或者是I would much appreciate it if you could send me the reply as soon as possible。
