【说明】其中的动词通常为连系动词，也就是说位于句首的名词是其后连系动词的表语。另外，要特别注意位于句首的名词前习惯上不用冠词，即使其前有形容词修饰也不用冠词。比较：

Boy as [though] he is, he likes to play with girls.=Though [Although] he is a boy, he likes to play with girls. 他虽是男孩，却喜欢与女孩子玩。

Strong man as [though] he is, General Botha has been severely put to the test during the past few weeks.= Though [Although] he is a strong man, General Botha has been severely put to the test during the past few weeks. 波赛将军虽然坚强，但在过去的数周里也受到了严峻的考验。

【说明】有的词典将much as 作为习语看待，认为它是一个用以引导让步状语从句的复合连词。再如：

Much as I like you, I couldn’t live with you. 我尽管很喜欢你, 却不能和你在一起生活。

【三条补充说明】

1. 这类倒装的让步状语从句可用as, though 来引导，但不能用although来引导；但是，未倒装的让步状语从句则可用though, although来引导，而不能用as来引导。也就是说，although 引导让步状语从句时不能倒装，as引导让步状语从句时必须倒装，而though引导让步状语从句时可以倒装也可以不倒装。如：

虽然很晚了，但我们还是继续工作。

正：Late as [though] it was, we still went on working.

正：Though [Although] it was late, we still went on working.

误：Late although it was, we still went on working.

误：As it was late, we still went on working.

2. 上面提到的倒装结构有时也可用来表示原因，区别的办法主要看句子的内容：让步从句的内容大多数与主句在意义上相反，而原因从句则与主句之间有因果关系。比较：

Tired as he was, he sat up late studying at night. 昨晚他虽然很疲倦了，但还是学习到很晚才睡。(表让步)

Tired as he was, he went to bed early. 因为很累，所以他睡得很早。(表原因)

Young as he was, he was equal to the task. 他虽年轻，却能胜任这项工作。(表让步)

Young as he was, he was not equal to the task. 他因为年轻，所以不能胜任这项工作。(表原因)

3. 在美国英语中，人们通常用as…as引导让步状语从句。如：

Cold as it was, we went out.=As cold as it was, we went out. 尽管天气冷，我们还是出去了。

Successful as he is, he is not proud.=As successful as he is, he is not proud. 他虽成功了，但不骄

Be动词和助动词用法辨析

Be动词和助动词用法区别其实be动词也是助动词（auxiliary verbs）。英语动词大致可分为三种：助动词（auxiliary verbs），情态动词（modal verbs），实意动词（full verbs）。助动词（auxiliary verbs）：do，be，have。没有实意，“帮助”别的动词，表示时态，否定和提问。情态动词（modal verbs）：can，must，may。也是“帮助”别的动词，但是有自己的实意。实意动词（full verbs）：play，run，think。其他有实意的动词。 be动词可用作助动词（auxiliary verbs）：1，be+Ving：所有的进行时态，如：2，be+过去分词：被动式。 be动词也可用做实意动词（full verbs）：be[bi]v.有；在；是。你这样想，一个句子里要有动词吧。再看看它们的名字，“be 动词”和“助动词”，先说“be动词”，（1）这名字里有动词，说明他是动词，句子里有他就不会有别的动词（除非这些动词以别的形式出现，这是后话）了，（2）“am,is,are,was,were”叫be动词，是因为他们是be的不同形式再说“助动词”，（1）一定要注意“助”，是帮助的意思，说明他不是动词，只是起到了辅助的作用，所以，他们就一定要与动词同时出现。[记住啊，他们离不开动词，但是动词没有他们也是可以的]

（2）did,do,does只是do的不同形式，根据你所需要的时态来选择（1）用于肯定句，否定句和疑问句 am：第一人称单数（即只与I连用），用于现在时（一般现在，现在进行，只要那时态中是现在的就行）eg:①I am a girl.一般现在时②I am eating an apple.现在进行时 ③I am going to do my homework.[be going to表将来，将来中只有这一种] is：第三人称单数，用于现在时（一般现在，现在进行，只要那时态中是现在的就行）(it就不举例了)eg:①She/He is a girl/boy.一般现在时②He/She is eating an apple.现在进行时③He/She is going to do his homework.[be going to表将来，将来中只有这一种] are：第二人称单数，所有人称复数，用于现在时（一般现在，现在进行，只要那时态中是现在的就行）eg:①You are a girl. We/You(你们)/They are girls.一般现在时②You are eating an apple.We/You(你们)/They are eating apples.现在进行时③We/You(你们)/They are going to do our/your/their homework.[be going to表将来，将来中只有这一种] was：第一人称单数，第三人称单数，用于过去时（一般过去，

however的用法

With the possible exception of the Beatles, no other band has become so successful so quickly. 可能除了披头士乐队这个例外，还没有哪个乐队如此转瞬走红的。并列句中连接词语的功能 2006-03-01 18:54:21 ??英语中，包含两个或两个以上互不依从的主谓结构的句子称为并列句，各个相互独立的主谓结构叫作分句，多数情况下并列句中的分句由并列连接词来连接。并列句的分句之间关系密切，而并列连接词是分句之间关系的纽带，它们起着承上启下的作用，显示了分句之间逻辑关系，指示了说话人思维的走向。因此，正确理解和掌握连接词语是我们能否正确理解话语篇章意义的关键。表示并列关系的词语除了并列连词（如：and，but，or，so，for等），还有并列词组（如：in addition，as a result 等）和连接性副词（如：however，moreover，otherwise等），这里统称为连接词语。根据连接词语的语义功能，可将其分类如下： 1．表示补充、添加关系的连接词这类连接词表示后面分句的句意是对前面分句句意的补充，说的是同类事情。常用的有：and，in addition，besides，moreover，furthermore，likewise，in the same way，what’s more 等。例如： Irene did not answer，and James，too，ceased speaking．艾琳没有回答，詹姆斯也不再说话。（说的都是"保持沉默"） Bicycling is good exercise，moreover，it doesn’t pollute the air．骑自行车是项很好的运动，而且又不污染空气。（说的都是骑自行车的优点） A flood will break a dam；likewise， the oppressed people everywhere will overthrow their oppressors in the end．洪水会冲毁大坝，同样，任何地方的被压迫人民也会推翻他们的压迫者。（说的是同一道理） 2．表示转折关系的连接词这类连接词表示后面分句在意义上与前面的分句发生了转折，说的是不同情况或不同的观点。常见的有：but，however，nevertheless，instead，on the contrary，on the otherhand，yet，by contrast，whereas等。例如： The situation looked desperate，but they didn’t give up hope．形势看来非常危急，但他们没有放弃希望。 It’s too wet to go for a walk；let’s go swimming instead．天气潮湿，不宜去散步，我们改去游泳吧。 There was no news；nevertheless，she went on hoping．尽管没有消息，她仍抱着希望。 3．表示因果关系的连接词

助动词的用法大全

助动词的用法大全助动词的形式与作用 1)英语常用的助动词(auxiliary verb)有shall，will，should，would，be，have，do等。助动词一般无词义，不能单独作谓语动词。助动词在句中的作用，在于帮助构成各种时态、语态、语气、否定和疑问结构等。如：China has entered a great new era. 中国已进入了一个伟大的新时期。(帮助构成完成时态) Some boys are playing on the grass. 一些男孩正在草地上玩。 (帮助构成进行时态) Mother is written by Gorky. 《母亲》是高尔基写的。 (帮助构成被动语态) We Shall have the football match if it does not rain.如果不下雨，我们就赛足球。(帮助构成将来时态和否定结构) Do you see my point? 你明白我的意思吗?(帮助构成疑问结构) [注]在否定结构中，not须放在助动词后面。 2)助动词加not一般都有简略式，用于口语中。如： is not-isn't would not--wouldn't are not--aren't [B:nt] have not--haven't was not -- wasn't has not--hasn't were not-- weren't [wE:nt] had not--hadn't shall not--shan't [FB:nt] do not--don't [dEunt] will not--won't [wEunt] does not--doesn't

but,however,while,although和though用法小结

but, however, while, although和though用法小结【观察】阅读下列句子，注意各句中黑体单词的用法。 1. We have made some achievements, but we should be modest. 2. He promised to help me. However, he is busy and hasn’t come. 3. She felt ill. She went to work, however, and tried to concentrate. 4. He said that it was so; he was mistaken, however. 5. You like sports, while I’d rather read. 6.

I heard nothing, though. 【归纳总结】 ★but与however均可表示转折，意为“但是，然而”，都可以引出表转折意义的句子（句1-句4），但二者用法也有区别： 1. 从语义上看，but所表示的是非常明显的对比，转折的意味较however要强。 2. 从语法上看，but是个并列连词，而however却是个连接副词（句2-句4）。 3. 从语序上看，but总是位于它所引出的分句之首，而however可位于句首、句中或句尾。

it 做形式主语和however 用法

不管however以何种形式出现，它都不外乎以下两种用法。 1. 用作副词 (1) 表示让步：意为“无论如何”“不管怎样”，用来修饰形容词或副词，其词序为：however+形容词或副词+主语+谓语。这样用的however其实具有连词的功能，用以引导让步状语从句。如： however much he eats, he never gets fat. 不管他吃多少，他永远吃不胖。用于此用法时，请注意以下几点： ①此用法属however所有用法中最重要的考点，同学们务请引起高度重视。 ②这样用的 however 与 no matter how 大致同义。如： People always want more, however [no matter how] rich they are. 人总是富了还想再富。 however [No matter how] hard I worked, she was never satisfied. 无论我多么努力地工作，她从来没满意过。 ③有时从句谓语可用情态动词。如： Don’t laugh, however funny it may be. 无论多么有趣也不要笑。 I’ll try to finish it in time, however hard it may be. 无论多么难，我也要按时完成。 ④“however＋形容词或副词＋主语＋谓语”有时可以有所省略。如： I refuse, however favorable the conditions. 不管条件如何有利，我都不干。(conditions 后省去了are) I’d rather have a room of my own, however small (it is), than share a room. 无论房间多么小，我宁愿一个人住一间，而不愿意与别人合住一个房间。 A grammar rule, however true (it is), is useless unless it can be understood. 一条语法规则，不管如何正确，除非能懂，否则毫无用处。 (2) 表示转折：尤其用于谈及一个既成事实时，表示转折，其意为“可是”“仍然”等。可放在句首、句中或句末，通常用逗号与句子其他成分隔开。如： My father, however, did not agree. 但是，我父亲不同意。 My room is small; however, it’s comfortable. 我的房间很小，但却很舒服。 He said that it was so; he was mistaken, however. 他说情况如此，可是他错了。注：however不能像 but(但是)那样直接连接两个句子(注意正句中的标点符号)。如：我们都已尽了最大的努力，不过我们还是输了。. 正：We all tried our best, but we lost the game. 正：We all tried our best; however, we lost the game. 正：We all tried our best. however, we lost the game. (3) 表示惊奇或强调：相当于how ever的用法，其意为“究竟怎样，到底以什么方式”。如：however did you get here without a car? 没有汽车你究竟是怎样来的呢? No matter +疑问词或者疑问词-ever 含义为“无论……都, 不管……都”。他们引导让步状语从句，并且可以互换。
