[析] 副词在句中的位置很活，但主要有以下几种用法：①实意动词之前，如：He quickly give me the answer. ② 在be动词之后，如：The little boy is often late for class. ③ 第一助动词之后，如：This book has almost been finished. ④ 在单独使用的be动词和助动词之前，如： Can you help me this afternoon? 　I certainly can.　但是无论如何也不能将副词置于动词与宾语之间，如果是宾语从句或是很长的名词

　　词组作宾语则才可以这样用：

　　He heard clearly what the teacher said.

　　[误] The children came late yesterday to the cinema.

　　[正] The children came late to the cinema yesterday.

　　[析] 表示一定长度的时间的副词不应放于句中，可放于句尾。如果表示强调则可放于句首。

　　[误] You have few new books, haven't you?

　　[正] you have few new books, have you?

　　[析] 英语中的数量形容词有两组。修饰可数名词的有few(很少，几乎没有)，a few(有一些，几个);修饰不可数名词的有little (很少，几乎没有)，a little(有一点，有一些)。要注意的是当few和little用于句中时应看作否定句，而 a few 和a little 用于句中时则应看作是肯定句。

　　[误] He spent quite little money on his food.

　　[正] He spent quite a little money on his food.

　　[析] quite a 为一固定用法，其意为"十分，相当，所以"。 quite a few=many, quite a little=much 而only a little=little, only a few=few.

　　[误] Do you want to have many bread?

　　[正] Do you want to have some bread?

　　[析] some与any都可以用作形容词、副词或代词，在一般情况下，some用于肯定句，any用于疑问句和否定句，但在希望得到肯定答复时，应用some。 其次是some 可以用来修饰可数名词和不可数名词。

　　[误] Please tell me wher the shoes shop is?

　　[正] Please tell me wher the shoe shop is.

　　[析] 在用名词作修饰词来修饰另一名词时，这个作修饰词的名词应用单数形式，如：

　　a shoe shop 鞋店

　　a fruit shop 水果店

　　a book shop 书店

　　a post office 邮局

　　a police station 警察局

　　a bus stop 汽车站

　　[误] He is weak at physics.

　　[正] He is weak in physics.

　　[析] 在表达擅长于作某事时用be good at something, 而其反意词为be bad at something， 但be weak in something。

　　[误] This dictionary is worth to buy.

　　[正] This dictionary is worth buying.

　　[析] be worth 后可接动、名词表达值得作某事，又可接价格、金钱表示值多少钱。

　　[误] Don't afraid of that.

　　[正] Don't be afraid of that.

　　[析] afraid 在英文中是形容词而不是动词。这样的词组还有：

　　be afraid of 害怕 be careful of 小心

　　be certain of 有把握，确定 be sure of 确信

　　be glad of 高兴 be sick of 厌恶

　　be fond of 喜欢

　　[误] The work has already been done well.

　　[正] The work has already been well done.

　　[析] well 与badly作副词时，表示好坏，如果句子是被动语态，则应放在过去分词之前，如：This machine has been badly damaged. 如果句子是主动语态，则应放于句末，如：I did my homework well.

　　[误] We are yet in the classroom now.

　　[正] We are already in the classroom now.

　　[析] already主要用于肯定句，而yet多用于否定句和疑问句中，如：

　　Did you finish it? No. not yet.

　　[误] Look. Here comes he!

　　[正] Look! Here he comes!

　　[误] Look! Here the bus comes!

　　[正] Look! Here comes the bus!

　　[析] 在句子开头用Here时，如主语是人称代词则不要用倒装语序，如果主语是名词则要用倒装语序。

　　[误] She is my older sister.

　　[正] She is my elder sister.

　　[析] elder 和eldest是用来指家庭中兄弟姐妹的长幼关系，而older, oldest 则是指岁数大多少，如：She is three years older than I.

　　[误] I'm tired. I can't go further.

　　[正] I'm tired. I can't go farther.

　　[析] far有两个比较级 farther 较远的，further 进一步的，如：Do you need any further explanation? 你需要进一步的解释吗?当然它也有两个高级。farthest和furthest.

　　[误] I went to Beijing University five years before.

　　[正] I went to Beijing University five years ago.

　　[析] ago常与过去时连用，而before则多与完成时连用。

　　[误] - Have you finished your homework??

　　- No, not already.

　　[正] - Have you finished your homework??

　　- No, not yet.

　　[析] 仍然有三个英文字可以表达它们是already， yet 与 still。 要注意的是 already经常用于肯定句中，如The bus has already gone。 而yet 多用于疑问句和否定句中，如：Have you finished your homework yet? 而still则常用于主语与谓语动词之间，如：We still can't decide what to do. 但也有时用于be 动词之后，如：He is still here.

　　[误] He is very higher than I am.

　　[正] He is much higher than I am.

　　[析] much可以用来修饰比较级，而very则用来修饰形容词原级，如：I'm very tired.

　　[误] - Can I walk to the station??- You'd better not. It is very far.

　　[正] - Can I walk to the station??

　　- You'd better not, It is a long way.

　　[析] for一般用在疑问句与否定句中，如：How far is it from here to the station? 又如：It isn't far.

　　[误] I've ever been to America.

　　[正] I've been to America once.

　　[析] once 多用于肯定句，而ever则用于疑问句，否定句，及条件状语从句中，如：Have you ever been to London?

　　[误] - Could you pass the exam this time??

　　- No, I am not afraid so.

　　[正] - Could you pass the exam this time??

　　- No, I'm afraid not.

　　[析] 在肯定的答语中我们可以用so来代替上句所讲的事件，如：Do you think she is a good student? Yes I think so, /I hope so, /I believe so/ I'm afraid so.但在否定的答语中，英语口语的习惯用法则有所不同，如，I don't think so 而在hope, belive 与 afraid后则常用not， 如：I hope not.

　　[误] She didn't work enough hard, so she couldn't pass the exam.

　　[正] She didn't work hard enough, so she couldn't pass the exam.

　　[析] enough 可以作名词用，如：Enough has been said for how to learn English well. (对于如何学好英语已经讲的足够多了。)　另外它可以作为形容词，如：I have enough money (or money enough) to buy this dictionary. 注意 enough作为形容词时即可放于名词前又可放于名词后，在初中范围的考题中多用于名词之前。如果enough 作为副词用，那么它一定要放在被修饰的形容词或副词之后。

　　[误] You can't be very careful.

　　[正] You can't be too careful.

　　[析] 此句话的含意是你如何小心也不过分。too…to的用法是"太……以至于不能作某事"。但在实际应用时也常常将后面的to省去，如：It is too expensive for me.那对我来讲是太贵了。

　　[误] He is good past fifty.

　　[正] He is well past fifty.

　　[析] well 作为副词用时除用于"好"之外还有"大大地、远远地"，等意。往往有人对下面两句的对或错有争议;

　　He is well.

　　He is good.

　　其实这两句都是正确的表达法，只不过其含意不同。He is well是"他身体不错"，而He is good 则为"他是个好人"。

　　[误] She is not as half clever as her brother.

　　[正] She is not half as clever as her brother.

　　[析] 在as…as结构中要将修饰形容词的数量词倍数及nearly, almost, exactly… 等置?于第一?个as之前。

　　[误] He is same age as Tom.

　　[正] He is the same age as Tom.

　　[析] the same…as是固定的用法，其中定冠词the是不可省也不能换成别的词的。

　　[误] Mother and her daughter are exactly like.

　　[正] Mother and her daughter are exactly alike.

　　* like 作为介词，其意为"像"，应用于 look like, be like, sound like, 其后要加宾语。而 ?alike? 是形容词，或副词，如: You and I think alike. The twins are dressed alike。 但 alike 仅作表语而不能用于名词前作定语。

　　[误] Who is taller of the two?

　　[正] Who is the taller of the two?

　　[析] 两者的比较级之前要加定冠词。

　　[误] I have less books than Tom.

　　[正] I have fewer books than Tom.

　　[析] less 是 little的比较级，而fewer是few的比较级。less后应加不可数名词而fewer后是可数名词。

　　[误] There are three girls in my group. The cleverer is Mary.

　　[正] There are three girls in my group. The cleverest is Mary.

　　[析] 在两者之间应用比较级，在三者之间或三者以上的范围内应用高级。

　　[误] The boy sat there as quiet as his sister.

　　[正] The boy sat there as quietly as his sister.

　　[析] as…as的用法要注意的是：①在其中间应加形容词或副词的原级，而不可加比较级，也有的语法书中称为同级比较。②要根据句意决定是加形容词还是副词，这要看它具体是修饰动词还是名词而定，如：He is as good as his friend.

　　[误] The harder you study, and you can learn more.

　　[正] The harder you study, the more you can learn.

　　[析] 英文中如果要表达越来越怎样，在初中范围有两种表达法：①比较级+and+比较级。②定冠词+比较级……，如：The nights are getting longer and longer。 要注意的是多音节形容词的比较级前要加more，这样的用法是：more and more 加形容词，如：The girl is growing more and more beautiful.

　　[误] Studying physics is not so interesting as to learn English.

　　[正] Studying physics is not so interesting as learning English.

　　[析] 在作比较时，英语一般要求对比的两部分结构应一致。如用动名词，应都用动名词，用不定式时则都用不定式。但有时在后一个不定式前的符号to可以省略。 如：To repair the old one is as much expensive as (to) buy a new one.

　　[误] The girl is more cleverer than the boy.

　　[正] The girl is much more clever (much cleverer) than the boy.

　　[析] clever有两个比较级：cleverer和more clever,要注意的是不能用比较级来修饰比较级。　clever的两个比较级也各有不同之处，如用在两种不同性质的比较时多用more clever,如：He is more clever than honest. (他的聪明要远远超过其诚实。)

　　[析] The boy is the tallest to the three.

　　[正] The boy is the tallest of the three.

　　[析] 高级的范围要用of加复数形式或加集合名词。

　　[误] This book is one of the most useful dictionary.

　　[正] This book is one of the most useful dictionaries.

　　[析] 在one of 后面高级形容词后要加可数名词复数。

　　[误] This dictionary is the much best one of the English?Chinese dictionaries.

　　[正] This dictionary is much the best one of the English?Chinese dictionaries.

　　[析] 在修饰高级时应用 far/by far/much 加the加高级。但very例外，如：He is the very best player in the team.

　　[误] Shanghai is bigger than any other cities in China.

　　[正] Shanghai is bigger than any other city in China.

　　[析] 在比较级中表示比较对象时如用any other其后一般要加单数名词。

　　[误] Most of stories in this book are written in English.

　　[正] Most of the stories in this book are written in English.

　　[正] Most stories in this book are written in English.

　　[析] "大多数"一词的表达法有most of the +名词，或most+名词。当用前一种结构时，其后面的定冠词不可少。

　　[误] The temperature of that room is higher than this room.

　　[正] The temperature of that room is higher than that of this room.

　　[析] 比较级用于两句话之间时，比较的部分不可省略掉，但为了避免重复，一般都要用that代替前面的单数名词，而用those代替前面的复数名词，如：The books in that box are bigger than those in this box。

　　[误] He is no more here. Maybe he is at home.

　　[正] He is no longer here. Maybe he is at home.

　　[析] no more在现代英语中多译为："从此再也不会了"，如：His voice is no more here. 他已经去世了，他的声音不可能再出现了。而用no longer 表达目前的状态。要注意下面几组句子的实际含意：　This room is no cleaner than that one.即两间屋子都不干净。(两者都不干净) This room is not cleaner than that one,即这屋子不如那间干净。(前者不如后者干净。即一间干净，一间不干净。)
