不定冠词的基本用法:
(1)不定冠词有a和an两种:a用于辅音音素开头的词前,an用于元音音素开头的词前。
例如:a boy, a city, a girl, a useful animal , an old man, an honest boy, a bad apple, a tall elephant
(2) 用来表示“一”的意思,但不强调数的观念,只说明名词为不特定者。即不具体说明是何人何物。
例如:A teacher is looking for you. We work five days a week.
(3)不定冠词含有“一”的意思,但数量观念没有one强烈,在句子里边一般可以不必译出,但若有“一个”的意思则译出,
例如:An orange is good for you. 桔子对你有好处。
(4)一般用在可数名词单数前,指人或事物的某一种类。
例如:Bill is a student. This is a ruler.
(5)用在某些固定词组中。
例如:a lot of, a moment ago, a few, a little
an与a的区别:
1)a用在以辅音字母开头,或以读做辅音的元音字母开头的单词前面:
例如:a man一个男人 a university一所大学 a hat一顶帽子 a European一个欧洲人
2)an用在以元音字母(a,e,i,o,u)开头,或以不发音的h字母开头的单词前面:
例如:an apple一个苹果 an island一个岛 an uncle一位大叔 an onion一个洋葱 an egg一个鸡蛋 an hour一小时
3)an还用在发音以元音开头的单个字母前面:
例如:an L-plate一块“实习驾驶”车牌 an MP一个国会议员 an SOS一个呼救信号 an‘x’一个x字母、X形的东西或未知数
4)a/an没有性的变化:
例如: a man一个男人 a woman一个女人 an actor一个男演员 an actress一个女演员
不定冠词与数词one区别:
不定冠词与数词one都可表示“一”的意思,前者可视为后者的弱式。
如:I have a [one] brother and two sisters. 我有一个兄弟和两个姐妹。
但是,尽管两者有时可换用,但由于两者词性和用法不同,在多数情况下不能互换,其主要区别有以下几点:
区别一:
从本质上说,不定冠词侧重指“类别”概念,而数词one侧重指数量概念。有时尽管两者都可用,但含义有差别:
I bought a dictionary yesterday. 我昨天买了本词典。(意指买的是词典,不是语法书,也不是钢笔等)
I bought one dictionary yesterday. 我昨天买了一本词典。 (意指买的是一本词典,不是两本或三本词典等)
"Can a boy do it?" "No, but a man can." “小孩做得了吗?”“做不了,要大人才行。”
"Can one boy do it?" "No, but two (boys) can." “一个小孩做得了吗?”“不行,要两个小孩才行。”
区别二:
当要强调数量概念或进行数量对比时,只能用数词 one。如:
"How many pens do you have?" "I have one (pen)." “你有几支钢笔?”“我有一支钢笔。”
I want one apple, not three apples. 我要一个苹果,不是三个苹果。
区别三:
若不是表示“一”的数量概念,而是表示“类别”概念,则只能用不定冠词。如:
A computer is useful. 电脑是有用的。
He is an excellent teacher. 他是位优秀的教师。
区别四:
在某些短语中,两者均可用,含义相同。如:
at a [one] blow 一下子,一举
in a [one] word 一句话,总而言之
而在某些表达中,两者均可用,但含义不同。如:
at a time 每次,同时
at one time 一度,曾经
还有一些表达,两者均可用,虽含义相同,但表达不同。如:
on a hot summer afternoon 一个炎热的夏日的下午 (用介词 on)
one hot summer afternoon 一个炎热的夏日的下午 (不用介词 on)
an hour and a half 一个半小时 (不说 one hour and a half)
one and a half hours 一个半小时
a minute or two 一两分钟 (不说 one minute or two)
one or two minutes 一两分种
注意,在绝大多数习语中,两者是不能换用的。如:as a result 结果,all of a sudden 突然,one day 一天,one by one 一个一个地,等等。
区别五:
与表示时间或度量衡的名词连用表示“每”时,只用不定冠词。如:
Brush your teeth twice a day at least. 每天至少要刷牙两次。
They are sold at two dollars a dozen. 他们的售价是每打两美元。

情态动词:
是一种本身有一定的词义,但要与动词原形及其被动语态一起使用,给谓语动词增添情态色彩,表示说话人对有关行为或事物的态度和看法,认为其可能、应该或必要等。
情态动词后面加动词原形。情态动词词义不完全,不能单独作谓语,只能与动词原形一起构成谓语。
情态动词有四类:
①只做情态动词:must,can(could),may(might)……
②可做情态动词又可做实义动词:need,will
③具有情态动词特征:have(had,has) to,used to,ought to
④情态动词表猜测:一肯一否三不定(must一肯,can not一否,may,might,could,三不定。)
注:mustn't代表强烈禁止 must表示主观,have to表示客观。
常用的有:can may could must have use .(can,may,must,should,need)
例:Kate can swim. 凯特会游泳。
May I borrow your dictionary, Ann? 安,我可以借用你的字典吗?
Shall we meet at seven o’clock tomorrow? 我们明天七点见面怎么样?
比较can 和be able to:
1.can/could 表示能力;可能 (过去时用could), 只用于现在式和过去式(could)。
be able to可以用于各种时态。例如:
They will be able to tell you the news soon. 他很快就能告诉你消息了。
2.只用be able to的情况:
a.位于助动词后。
b.情态动词后。
c.表示过去某时刻动作时。
d.用于句首表示条件。
e.表示成功地做了某事时,用was/were able to,不能用could。例如:
He was able to flee Europe before the war broke out.= He managed to flee Europe before the war broke out.
他在战争爆发之前逃离欧洲。
注意:could有时不表示时态
1.提出委婉的请求,(注意在回答中不可用could)。例如:
Could I have the television on? 我能看电视吗?
Yes, you can. / No, you can't. 可以/不可以。
2.在否定句、疑问句中表示推测或怀疑。例如:
He couldn't be a bad man. 他不大可能是坏人。
比较may和might:
1.表示允许或请求;表示没有把握的推测;may 放在句首,表示祝愿。例如:
May God bless you! 愿上帝保佑你!
He might be at home. 他可能在家。
注意:might 表示推测时,不表示时态,只是可能性比may 小。
2.成语:may/might as well,后面接不带to 的不定式,意为"不妨"。例如:
If that is the case, we may as well try.如果情况确实如此,我们不妨试一试。
比较have to和must:
1.两词都是“必须”的意思,have to 表示客观的需要,must 表示说话人主观上的看法,既主观上的必要。例如:
My brother was very ill, so I had to call the doctor in the middle of the night.
弟弟病得很厉害,我只得半夜里把医生请来。(客观上需要做这件事)
He said that they must work hard.
他说他们必须努力工作。(主观上要做这件事)
2.have to有人称、数、时态的变化,而must只有一种形式。但must 可用于间接引语中表示过去的必要或义务。例如:
He had to look after his sister yesterday. 他昨晚只得照顾他姐姐。
3.否定结构中:don't have to表示"不必",mustn't表示"禁止"。例如:
You don't have to tell him about it.你不一定要把此事告诉他。
You mustn't tell him about it.你不得把这件事告诉他。
比较shall和should:
1).shall 用于第一人称,征求对方的意见。
What shall we do this evening?
2).shall 用于第二、三人称,表示说话人给对方的命令、警告、允诺或威胁。
①. You shall fail if you don’t work hard.(警告)
②. He shall have the book when I finish it.(允诺)
③. He shall be punished.(威胁)
will和would的用法:
1.表示请求、建议等,would比will委婉客气。如:
Would you pass me the book?
2.表示意志、愿望和决心。如:
I will never do that again.
They asked if we would do that again.
3.用“will be”和“will(would) + have + 过去分词”的结构表示推测,主要用于第二、三人称。
前者表示对目前情况的推测,后者表示对已经完成的动作或事态的推测。如:
This will be the book you want.
He will have arrived by now.
The guests would have arrived by that time.
I thought you would have finished this by now.
4.will表示习惯、请求,固有性质等。
Everyday he will sit here hour after hour doing nothing.(习惯)
Will you help me with my English?(请求)
The door won't open. (固有性质)
5.Would可表示过去反复发生的动作或某种倾向。
Would表过去习惯时比used to正式,并没有“现已无此习惯”的含义。如:
The wound would not heal.
During the vacation he would visit me every week。
6.表料想或猜想。如:
It would be about ten when he left home.
What would she be doing there?
I thought he would have told you all about it.
情态动词用法口诀:
情态动词两特点,动词原形接后面,说话语气较委婉。
can"能力"may"许可",must"责任"或"义务"。
否定回答needn’t换,"需要"need,dare"敢"。
should"应该",would"愿",haveto"被迫"表客观。
一般疑问句的改写:
一、含有be动词的一般疑问句,通常把be动词调到句首。例如:
陈述句:They are in the swimming pool.
一般疑问句:Are they in the swimming pool?
注意:一般疑问句句末要用“?”。
二、含有情态动词的一般疑问句(can, may...),把情态动词调到句首。例如:
陈述句:He can drive a car.
一般疑问句: Can he drive a car?
三、含有have的一般疑问句,have译为“有”。一般疑问句式有两种形式:
1.把have/has调到句首。例如:
陈述句:Tommy has a computer.
一般疑问句:Has Tommy/he a computer?
2.加助动词do/does,第三人称单数用does,其他人称用do。其句型为:Do/Does + 主语 + have...?
例如上句可变为: Does Tommy have a computer?
四、一般动词的一般疑问句,也要借助助动词do/does,第三人称单数用does,其余人称用do。
其句型为:Do/Does + 主语 + 动词原形+其它?
陈述句:Amy speaks English.
一般疑问句:Does Amy speak English?
一般疑问句的回答:
首先要有人称的改变。当主语为名词时,在答语中要改成其相应的代词。
另外,答语有两种,肯定的回答(用yes)和否定的回答(用no),否定式常用缩写形式。
现在还是让我们分句型一一说明。
一、一般疑问句含be动词时,用be动词回答,句末用句号。例如:
-Is Mary your sister?
-Yes, she is. / No, she isn’t.(缩写)
二、一般疑问句含有情态动词(can, may, should等)时,用情态动词回答。例如:
-May I come in?
-Yes, you may. / No, you can’t.
三、一般疑问句含有have(译为“有”)时,有两种回答方式。
1.直接用have/has回答。
例如:
-Have they any pictures?
-Yes, they have. / No, they haven’t.
2.用助动词do/does回答。
例如:
-Does Millie smoke?
-Yes, she does. / No, she doesn’t.
四、一般动词的一般疑问句回答时也用助动词。
例如:
-Do the workers live in London?
-Yes, they do. / No, they don’t.
