完全否定
英語中的完全否定可以用not, no, never, none, nobody, nothing, neither...nor, nowhere等表示。
如:
1.Nothing is difficult for him. 沒什么難得到他。
2.Mary never has beef. 瑪麗從來不吃牛肉。
3.Neither answer is correct. 兩種答案都不對。
部分否定
英語中表示“全體”意義的代詞, 形容詞或副詞。如:all, both, altogether, always, completely, every day, everyone, everything, everywhere, every, everybody, many, often等與not搭配時,通常表示部分否定,意思是“并非都是”“不完全是”“不是每個都是”等。
例如:
1.Not everyone was amused by these April Fool's jokes.
并不是每個人都覺得這些玩笑有趣。
2.Food likes and dislikes do not always seem related to nutrition. 對食物的好惡似乎并不總與營養(yǎng)有關(guān)。
比較:
Nothing makes him happy.
(全部否定)沒有哪一件事情讓他開心。
Not everything makes him happy.
(部分否定)并不是每一件事都讓他開心。
None of the students went to visit the science museum last week.(完全否定)上周沒有一個學生去參觀科技博物館。
Not all of the students went to visit the science museum last week.(部分否定)上周并不是所有的學生都去參觀了科技博物館。
幾乎否定(半否定)
一些半否定詞表否定之意。他們不可再與否定詞連用,他們與謂語肯定式連用,構(gòu)成幾乎否定句。如:hardly, scarcely, seldom, little, few等詞。
例如:
1.I could hardly hear what he said.
我?guī)缀鯖]聽見他說了什么。
2.There is little water in the bottle, isn't there?
瓶子里幾乎沒有水,不是嗎?
雙重否定
雙重否定句由not + 具有否定意義的詞構(gòu)成,形成“否定+否定=肯定”的語言效果。雙重否定可以表示強調(diào),也可以表示委婉的含義。
例如:
1.Her name can't escape me forever.
我永遠忘不了她的名字。
2.The songs never fail to make the children smile.
這些歌曲一向都能使孩子微笑。
轉(zhuǎn)移否定
轉(zhuǎn)移否定,即句中的否定雖然出現(xiàn)在謂語部分,否定范圍卻不在主句謂語動詞本身,而轉(zhuǎn)移到了句子中的賓語、狀語或其他成分上。這種形式在初中比較常見的有以下兩種情況:
1.轉(zhuǎn)移否定多用于表思維活動
如:believe(相信), expect(期望), hope(希望), imagine(想象), think(認為)等。
例如:
I don't think he will pass the exam.
我認為他考試會不及格的。
2.主句的謂語動詞是表感覺的系動詞,通常也用于轉(zhuǎn)移否定句
這類動詞有:seem(好像), feel(感覺), appear(出現(xiàn)), look like(看起來像)等。
例如:
It doesn't look like it's going to rain.=It looks like it isn't going to rain. 好象不會下雨。
No matter how hard he studies, he never seems to be able to pass the exam. 不管他多么努力的學習,他似乎永遠也考不及格。
運用某些結(jié)構(gòu)表達否定意義
1.too...to 太……而不能

2.more A than B(與其B不如A)或more than +含有can的從句

這年輕人有勇無謀。
The gratitude for your help is more than I can express.
對于你給我的感激之情我無法言表。
3.prefer to do sth rather than do sth 寧愿(喜歡)……而不愿……,
例如:
He prefers to write his letters rather than dictate them.
他喜歡自己寫信而不愿口授自己的信。
運用含否定意義的詞或詞組表否定意義
1.動詞短語表否定意義,
如:
