3、有关副词的重要注释：
⑴ as…as…常构成一些词组：as soon as…(一旦…就…), as well as…(同样), as+形容词/副词+as possible(尽可能……地)。如：Please ring me up as soon as you get to Beijing.(请你一到北京就给我写信。)/ Miss Gao hurried to the school gate as quickly as possible.(高小姐尽快地赶到了校门口。)
[注释] “as long / much as + 名词”可以表示“长达/多达…”的含义。如：The house costs as much as five hundred thousand yuan.(那幢房子花费高达50万元。)/ They stayed in the cave(山洞)as long as two weeks.(他们呆在山洞里长达两周。)
⑵ later、after、ago、before的用法：①“一段时间+later/ago”分别表示“(多久)以后/以前”,主要用于过去时态。②“after/before+某个时刻”分别表示“在某时刻之后/之前”,此时两个词是介词。③ago与before：ago只能用于过去时,before用于完成时。如：He had an accident a week ago.(一周前出了一个事故)/ Some years later, the boy became a very famous singer.(数年后这个男孩成了著名的歌唱家)/ Have you been there before?(你从前到过那儿吗？)/ After a few years he gave up smoking.(过了几年他戒了烟。)
⑶ above、below、over、under的用法：在上下方用above和below,在高低处用over和under.如：The stars are high above in the sky.(星星高挂在空中) / A plane flew over quickly.(一架飞机从头顶飞过。)
当above、below、over、under是介词性质时,意义相似。
⑷ too、also、either、nor的用法：too(“也”)用于肯定句和疑问句的末尾,且用逗号隔开；also(“也”)用于肯定句句子谓语动词之前；either(“也”)用于否定句末尾,也用逗号隔开；nor(“也不”)用于倒装句句首；如：Are you American,too?(你也是美国人吗？)/ He is not happy and I am not happy, either.(他不愉快,我也不。) / He didn’t watch the football game. Nor did I.(他没有看足球赛,我也没有。)/ You can also find the market is very good.(你还可以发觉那个市场很好。)
⑸ enough、too、so、very、quite、very much的用法： enough (“足够,十分”)放在形容词或副词之后；too(“太”)、very(“非常”)、quite(“相当”)、so(“如此地”)等放在形容词或副词之前,very much(“非常”)放在动词之后。如：It’s too/so/very/quite expensive.(它太贵/那么贵/非常贵/相当贵。)/ I don’t like sweets very much.(我不很喜欢糖果)
[注意] very与 much的区别：very修饰形容词、副词的原级和现在分词形容词,much修饰形容词和副词的比较级；much还可以修饰疑问句和否定句中的动词,very不可以。如：He is very stupid.(他很笨)/ The film was very moving and everyone swept.(电影非常动人,大家都哭了)/ You must work much harder or you will fail to enter the good school.(你得学习更努力,不然你考不进那所好学校)/ I don’t like him much.(我不太喜欢他)
⑹ sometimes、 sometime、 some times 、some time的用法：sometimes(有时)用于一般现在时、 sometime(在将来某时)用于将来时、 some times(数次)表示次数、some time(一些时间)表示一段时间。如：Sometimes they go hiking in the mountains.(他们有时徒步旅行到山里去)/ I will stay here some time.(我会在这儿呆些时候的。)/ I will meet your father sometime.(我什么时候要见见你的父亲。)
⑺ how、what用于感叹句的用法：对句子中的形容词或副词感叹时用how,对人或事物(可能含有形容词作修饰语)进行感叹用what. 如：What a fine day (it is) today!(今天天气真好！) / How difficult (the problem is)!((问题)真难呀！)
⑻ already、yet的用法：在完成时中,already一般用于肯定句,yet一般用于否定句和疑问句。如：Have you done it already?(你已经做好了？) / I have not had my breakfast yet.(我还没有吃早饭呢。)
⑼ hard与hardly的用法：hard作为副词意思是：“努力地,猛烈地”,hardly是否定词,意思是：“几乎不”,一般与情态动词can/could连用。如：They study English very hard.(他们英语学得很刻苦)/ You can hardly see a person spit in a public place.(在公共场所你几乎看不到一个人随地吐痰)
⑽ like...very much、like...better(=prefer)、like...best的用法：三个短语分别表示“非常喜欢”、“更喜欢”、“最喜欢”。如：I like baseball very much.(我非常喜欢棒球)/ Do you like butter better than cheese?( / They like hamburgers best.
⑾“quite/what+a+形容词+名词”的用法：记住：①quite/such/what...+a+形容词+名词;②too/so/how+形容词+a+名词;③rather+a+形容词+名词 = a+ rather+形容词+名词。如：I have never seen such a strange guy(家伙).(我从未见过这样奇怪的家伙) / It is quite a nice day for a walk.(这真是散步的好日子)
⑿ how 的几个短语：how often“多常,每隔多久”,用于一般时态,对表示频度的词语进行提问； how soon“多久以后”,用于将来时态； how long“多久”,用于过去时、完成时或其他时态； how many times“多少次”,用于过去时或完成时,对总计次数进行提问； how much“多么,多少”,对程度进行提问,也可以对数量(不可数)或金钱进行提问。如：How long have you been like this?(你这样已经多久了？)/ How often does he wash his face?(他每隔多久洗一次脸？)
⒀ much、more与most的用法：这三个词除了是形容词作名词的修饰语之外,还是程度副词,much表示“很”,修饰原级形/副,more表示“更”用来构成多音节形/副的比较级,most表示“最”用来构成多音节形/副的最高级。此外,much也可以修饰比较级形/副。如：This park is much more beautiful than that one.(这个公园比那个漂亮多了)/ It is the most instructive film I have ever seen.(这是我看过的最有教育意义的电影)
⒁ no more、no longer、not...any more、no...any longer的用法：表示时间,可以用no longer、not...ny more、no...any longer,而且no longer只能放在谓语动词之前；表示程度,可以用no more、not...any more.如：He no longer lived there.(他不再住在那里) / Tom wanted no more cakes.(他不想再要蛋糕) / He didn’ t smoke any more/longer.(他不再抽烟)
⒂ 被动语态中,方式副词一般放在be与谓语动词之间。如： The runner was badly hurt.(赛跑运动员受了重伤) / English is widely spoken in the world today.(如今世界上英语说得很广泛)
⒃ too...to...与so...that...的问题：副词too/so后面跟形容词或副词,to后面跟动词,that后面跟从句。Too...to... (“太.……以致不……”)是否定的结构,用于简单句；so...that...(“如此…以致…”)是肯定结构,用于复合句。如：The child is too young to join the army.(这孩子年龄太小还不能参军)/ He is so strong that he can lift the heavy box.(他这么强壮,搬得动那个重箱子。)
⒄ 既是形容词也是副词的单词有：early, late, long, last, next, first, near, enough, much, all, hard, alone, fast, slow, high, low, straight等等。如：It was a long holiday.(那是个长假)/ He stayed there very long.(他在那儿呆了好久)/ Think hard then you will find a way.(好好想你就会找到办法)/ He is a very hard(难对付的) person.(他是个难玩的家伙)
⒅ farther与further的用法区别：表示地点、方向或距离时两个词同义,意思为“更远、较远”,但是further还表示“更多、进一步、额外”等意思,此时不能换为farther. 如：They decided to go farther/further the next day.(他们决定第二天走得再远些)/ This problem will be further discussed.(这个问题还要进一步讨论)/ Every one of them had their further studies after they left college.(他们每个人大学毕业后继续进修)
⒆ rather与quite的用法区别：同very一样,两个词都表示形容词或副词的程度,quite表示“不到最高程度但是比预料的好”,rather比quite更接近very的含义,含有令人惊讶的意思。见下图对“nice”程度的描绘：
not nice (fairly) nice quite nice rather nice very nice
如：It’s quite a nice film.(这是部好片子)。(可能意味着不是一部最好的电影) / It’s rather a nice film.(这是部很不错的电影。)(意味着比大多数电影都好)
[注意]注意quite与rather后面的次序词序。
⒇ maybe、possibly、perhaps的区别：maybe“可能、也许”,比另外两个词更不正式、更随便、可能性不大；possibly“可能地、或者、也许”,可能性较大,在否定句和疑问句中表示“无论如何”；perhaps“可能”,较为常用而且正式,可能性也不大。如：You could put it over there,maybe.(也许你可以把它放在那边) / I couldn’t possibly have finished such a long book in such a short time.(我不可能在这么短的时间内完成这么长的一本书)/ I thought perhaps it was the letter you have been expecting.(我以为那也许就是你期盼的信件)
(21) most、mostly的区别：most作为形容词和名词时意思是“大多数的、大部分的”,作为副词时意思为“最,十分、很”；mostly仅为副词,意思为“主要地、多半地、大部分地”。如：I was at home most of the time when I was free.(我有空时大部分时间都在家)Most children are naughty.(大部分的孩子都淘气)/ This is the most exciting part of the film.(这是电影中最令人兴奋的部分)/She is mostly out on Sundays.(星期天她一般不在家)
(22) (be) worth、(be) worthy of的区别：worth一般被看作是介词,后面接名词或者动名词,用主动表示被动含义,还可以用副词well修饰；worthy of表示“值得的、配得上的”,后面跟动名词的被动形式。如：What is worth doing at all is worth doing well(凡是值得做的,就值得好好去做). / The house is worth ￥300,000.(房子价值30万元)/ This book is well worth reading several times.(这本书值得好好读几遍)/ It is a thing worthy of being seen.(这是一个值得看的东西)
(23)almost、nearly的区别：两个词意思相近,都表示“几乎、将近”,大多数情况下可以互换,与否定词连用时用almost不用nearly. almost no 相当于hardly any(几乎没有)。如：He had done almost nothing today.(他今天几乎没有干什么) / We are almost/nearly there.(我们几乎就到那里了)/ Almost nobody/Hardly anybody understood his words.(几乎没有人懂他的话)
(24) a bit与a little的区别：这两个名词短语经常当作副词使用,修饰形容词或副词的原级或比较级,可以互换,语气比rather弱。如：This digital camera is a bit(a little) expensive.(这台数码相机有点贵)/ It is a little(a bit) colder than yesterday.(今天比昨天冷了点)
另外,a little可以直接加不可数名词,a bit 则采用“a bit + of +名词(不可数或可数名词复数)”的形式。如：I have got a bit of a cold.(我有点感冒)/ Go and get a little water for me, please.(请你去给我搞点水来)
[注意] not a bit(=not at all)意为“根本不”,而 not a little则意为“非常,不是一点”。
3、形容词、 副词的原级、比较级和最高级
1、分类：形容词和副词有原级、比较级和最高级三级。
原级变为比较级和最高级有规则变化和不规则变化两种。
2、规则变化:
(1)单音节和部分双音节形容词和副词,在原级的后面加上er,est构成比较级和最高级。
a)直接加er,est ：
b)以重读闭音节结尾的,要双写最后一个辅音字母,后加er,est：
c)以辅音字母+y结尾的,先把y改为i再加上er,est：
(2)两个音节或两个以上的音节的,在原级前加more / most.
3、不规则变化:
| 原级 | 比较级 | 最高级 |
| good好的 | better更好的 | best最好的 |
| well好；(身体)好的, | ||
| bad,badly糟糕的,糟糕地 | worse更糟糕的,更糟糕地；(身体)更不舒服的 | worst最糟糕的,最糟糕地；(身体)最不舒服的 |
| ill(身体)不舒服的 | ||
| many许多的(可数) | more更多的；更 | most最多的；最 |
| much许多的(不可数)；非常 | ||
| little少的 | less更少的 | least最少的 |
| far远的；远地 | farther更远的；更远地 | farthest最远的；最远地 |
| further进一步的(地) | furthest最深刻的(地) |
4、形容词和副词的原级、比较级和最高级的用法：
(1)讲述某人/物自身的情况时,用原级。基本句型是：
主语(sb./sth) + 谓语动词 + (very/too/so/quite/rather…) + 形容词/副词原级 +….
如：He is very old now.(他现在很老了) / They ran quite fast.(它们跑得相当快) / The weather looks rather bad.(天气看上去相当糟) / I am so happy!(我是如此的快乐)
☆表示两者之间没有差别时,使用句型：
主语(第一个人物) + 谓语动词 + as + 形容词/副词原级 + as + 第二个人物 +….
如：He is as excited as his younger sister.(他和他妹妹一样兴奋)/ Lily rode her bike as slowly as an old lady.(莉莉骑车像老太太一样慢)/ They picked as many apples as the farmers (did).(他们摘的苹果和农民一样多)
☆表示第一个人比不上第二个人时,使用句型：
主语(第一个人物) + 谓语动词(否定式) + as / so + 形容词/副词原级 + as + 第二个人物+….
如：He is not so / as excited as his younger sister.(他没他妹妹那么兴奋) / Lily did not ride her bike so / as slowly as an old lady. (莉莉骑车不像老太太那样慢) / They didn’t pick so / as many apples as the farmers (did). (他们摘的苹果不如农民多)
(2) 讲述两者有差异,第一个人物超过第二个人物时,用比较级。基本句型：
主语(‘A’)+谓语动词+(much/a little/even/still)+形容词/副词比较级+than+第二个人物(‘B’)+….
如：A modern train is much faster than a car.(现代的火车比轿车快多了) / This book didn’t cost me more than that one.(这本书花费我的钱不比那本多)
讲述两者有差异,第一个人物不及第二个人物时,用比较级。句型是：
主语(‘A’) + 谓语动词 + less+ (多音节形/副)比较级 + than + 第二个人物(‘B’) +….
如：I think English is less difficult than maths.(我认为英语不比数学难)/ Do you think it less important to learn a foreign language?(你认为学外语不那么重要吗？)
(3)讲述某人/物是一群之中最突出的一个时,用最高级。句型是：
主语(sb./sth) + 谓语动词 +(the) +形容词/副词最高级 +in / of ….
如：The Changjiang River is the longest in China.(长江是中国最长的河流) / He jumped (the) highest of the three (boys).(三个男生中他跳得最高)
4、关于比较等级的重要注释：
1、以上六个句型中,如果动词是及物或不及物动词,则后面用副词；如果后面是连系动词,则后面用形容词。如：This car is the fastest of the four.(形容词)(这辆汽车是四辆之中最快的)/ This car runs (the) fastest of the four.(副词)(这辆汽车是四辆之中跑得最快的)
2、“比较级+and+比较级”表示“越来越……”。如：The weather is getting warmer and warmer.(天越来越温暖了)
3、“the+比较级…,the+比较级…”表示“越…就越…”。如：The more trees we plant,the better it will be.(我们栽的树越多,情况就会越好)/ The harder you try,the greater your progress is.(你越是努力,进步就越大)
4、一般的形容词或副词的比较级前面可以加much/a little/even/still,而表示数量的more之前还可以加some/ any/ no/ one/ two/ many/ several/ a lot等词。如：It is much colder today than yesterday.(今天比昨天冷多了)/ Would you like some more coffee?(你还要些咖啡吗？)/He did not eat any more.(他没有再吃)
5、more than / less than分别可以理解为“多于/少于”,相当于副词,more than=over; less than=under.如：I lived in New York for more than four months.(我在纽约生活了四个多月)
6、“one of the +最高级+名词(复数)”整个短语为单数含义,谓语要用单数形式。如：One of the oldest houses has been burnt in a fire.(最古老的一幢房子在一场大火中被烧毁了)
7、“Which / Who+动词+形/副,□,□or□?”句型中,如果有两个选项,形/副用比较级,如果有三个选项,形/副用最高级。如：Who has more books, Lin Tao or Han Mei?(林涛和韩梅谁的书最多？)/ Which is the heaviest,a pig,a horse or an elephant?(猪、马、象哪个最重？)
8、上下文中含有both/either/neither/two/twins等表示两个事物的词时,用比较级,而且往往还要加the；含有all/none/no one/ every 等表示三个或三个以上事物时,用最高级。如： --Do you like the smaller one?—Neither.(小一点的那个你喜欢吗？一个都不喜欢)/ --Which do you like best? –All of them!(你最喜欢哪个？全部。)
1、介词的主要用法：
介词是一种虚词,不能独立使用。介词之后一般有名词或代词(宾格)或相当于名词的其他词类、短语或从句作它的宾语,即构成介词短语。有些介词是由两个以上的词构成的短语介词,如：out of(从…中出来), because of(因为), away from(距离…), on top of(在…顶上), ever since(自从…), next to(在…隔壁), according to(根据…), in front of(在…前方)等。
2、介词的分类表： (见下表)
地点(位置、范围)介词：above在…前, about在…附近, across在…对面, after在…后面, against倚着..., along在…近旁, among在…中间, around在…周围, round在….周围, at在…处, before在...前, behind在...后, below低于..., beside在...旁边, between在...之间, by在...旁, down在...下面, from来自..., in在...里面, inside在...里面, near靠近..., of在...之中, on在...上面, out of在...之外, outside在....外面, over在....上方, under在...下方, up在...上面, on top of在...顶部, in front of在...前, close to靠近..., in the middle of在...的中间, at the end of在...的末端,等等。

3、介词短语的句法作用：
介词短语相当于一个形容词或副词,可用作状语、定语和表语。如：The man came <down the stairs>.(状)(那个人走下楼来)/The woman <with a flower on her head> is from the countryside.(定)(头上戴花的妇女来自乡下)/The teacher is now with the pupils.(表)(老师现在和学生在一起)
4、介词短语在句子中的位置：
介词短语做状语时,如果表示时间/地点,可以放在句首或句尾,如果表示方向/方式/伴随/涉及/原因/目的/比较,一般放在句尾； 介词短语作表语时放在连系动词之后；介词短语作定语时,只能放在被修饰的名词之后。如：He wanted to find a good job in Shanghai the next year.(状语)(他想来年在上海找份好工作)/ They searched the room for the thief.(他们在房间里搜索小偷) / The letters are for you.(表语)(信是给你的)/ Have you seen a cat with a black head and four white legs?(定语)(你看见一只黑头白腿的猫了吗？)
5、重要注释：
⑴ this / that / these / those / last / next / a / every / each等词构成的时间短语,前面不用任何介词。如：Every year travellers from abroad come to visit Pingyao.(每年都有国外的游客来游览平窑镇)/ He had a bad cold that week.(那个星期他患重感冒)
⑵ for有时用来引出动词不定式的逻辑主语,常翻译成“对于…而言”。如：It’s too hard for me to finish the work in only one hour.(让我在区区一个小时内完成这项工作太难了)/ The house is big enough for 10 men to live in.(房子够大的可以容10个人住)
⑶ of有时用来表示后面的人物正好是前面的表语的逻辑主语。如：It’s very nice/kind of you to do so.(你这么做真是太好了)
⑷ 介词有时会与它的宾语分离,而且宾语前置。
① 当宾语是疑问词时。Who are you talking about?(你们在谈论谁？)
② 宾语在从句中当连接词时。He has a younger brother who he must take good care of.(他有 一个需要他照顾的小弟。) / Do you know who our teacher is talking with over there?(你知道我们的老师在那边和什么人谈话吗？)
③ 动词不定式作定语且该动词为不及物动词,后面有介词。I finally found a chair to sit on.(我 最终找到了一张椅子坐。)
(5) 记住一些固定词组：arrive at/in(到达…),on foot(步行),not…at all(根本不),to the north of(在…以北),in the east of(在…的东部),in the night(在夜间),at night(在晚上),be afraid of(害怕…),be full of(充满/ 装满….),be filled with(充满/ 装满….),be good/bad for(对…有益/有害),be made of(由…做成),be made from(由…制造),play with(玩耍……),look out of(朝…外面看),at the end of(在…末梢/结束时),by the end of(不迟于…/到…末为止),with the help of或with one’s help(在…的帮助下),look after(照料…),look for(寻找…),on a bike(=by bike)骑车, help sb. with(帮某人做…),get on (well) with(与某人相处[融洽]),等等。
6、某些介词的用法辨析：
⑴ 时间或地点介词in、on、at的用法区别：表示时间时, in表示在一段时间里(在将来时句子中则表示在一段时间之后), on表示在具体的某一天或者某天的上下午等, at表示在某个时刻或者瞬间； 表示地点时, in表示在某个范围之内, on表示在某个平面上或与一个面相接触,at则表示在某个具体的场所或地点。如：He was born on the morning of May 10th.(他出生于五月十日的早晨)/ I usually get up at 7：00 in the morning.(我通常在早上的七点钟起床) / His glasses are right on his nose.(他的眼镜就架在他的鼻子上)/ He is at the cinema at the moment.(此刻他正在电影院)
⑵ after与in表示时间的用法区别：“after+(具体时刻/从句)”表示“在…时刻之后”常用于一般时态；“in+(一段时间)”表示“在(多久)之后”,常用于将来时态。如：He said that he would be here after 6：00.(他说他六点钟之后会来这儿)/ My father is coming back from England in about a month.(我父亲大约一个月以后从英国回来)
⑶ since与for表示时间的用法区别：“since+(具体时刻/that-从句)”表示“自从…起一直到现在”,“for +(一段斶间)”表示“总共有…之久”,都常用于完成时态；如：Uncle Li has worked in this factory since 1970.(李叔叔自从1970年起就在这家工厂工作了)/ Uncle Li has worked in this factory for over 30 years. (李叔叔在这家工厂已经工作了30多年)
⑷ by、in与with表示方式的用法区别：都可以表示“工具、手段”,但是by主要表示“乘坐”某个交通工具或“以……方式”,在被动句中可以表示动作的执行者；in表示“使用”某种语言/文字,with表示“使用”某个具体的工具、手段。如：We see with our eyes and walk with our feet.(我们用眼睛看东西,用双脚走路)/ Please write that article(文章) in English.(请你用英语写那篇文章)/ Let’s go to the zoo by taxi.(我们打的去动物园吧。)/ It was written by Lao She.(那是老舍写的)
⑸ about与on的用法区别：都可以表示“有关…”,但是about的意义比较广,而on主要表示“有关…(专题/课程)”。如：Tom is going to give a talk on the history of America.(汤姆要作一个美国历史的报告)/ They are very excited talking about the coming field trip.(他们兴致勃勃地谈论着即将来到的野外旅游)
⑹ through与across、over的用法区别： through指“穿过…(门洞/人群/树林)”； across和over可以指“跨越…(街道/河流)”,可互换,但是表示“翻过…”时只能用over. 如：Just then a rat (鼠)ran across the road.(就在那时一只老鼠跑过路面)/ There is a bridge across/over the river.(河上有座桥)/ They climbed over the mountain and arrived there ahead of time.(他们翻过大山提前到达了那里)/ The visitors went through a big gate into another park.(参观者们穿过一个大门来到另一个公园)
(7)as与like的区别：两个词都表示“像……”,但是as译为“作为……”,表示的是职业、职务、作用等事实,而like译为“像……一样”,表示外表,不是事实。如：Let me speak to you as a father.(我以父亲的身份和你讲话。)(说话者是听者的父亲) / Let me speak to you like a father.(让我像一位父亲一样和你讲话)(说话者不是听者的父亲)
(8)at the end of、by the end of、to the end、in the end的用法区别：at the end of…既可以表示时间也可以表示地点,译为“在…末；在…尽头”,常与过去时连用；by the end of…只能表示时间,译为“在…前；到…为止”,常用于过去完成时； in the end与at last基本等义,表示“终于、最后”,通常用于过去时；to the end译为“到…的终点为止”,前面往往有表示运动或连续性的动词。如：By the end of last term we had learned 16 units of Book III.(到上学期期末我们已经学习了第三册16个单元)/ At the end of the road you can find a big white house with brown windows.(在路的尽头你能找到一幢有棕色窗户的白房子)/ They left for Beijing at the end of last week.(上周末他们动身去了北京)/ In the end he succeeded in the final exams.(他最终在期末考试中考及格了)/ We should go on with the work to the end.(我们应该把工作干到底)/ Follow this road to the end and you will see a post office.(沿这条路走到底就能看见一家邮电局)
(9)for a moment、for the moment、in a moment、at the moment的区别：for a moment“一会儿、片刻”(=for a while),常与持续性动词连用；for the moment“暂时、目前”,常用于现在时；in a moment“一会儿、立即、马上”(=soon; in a few minutes),一般用于将来时；at the moment“此刻,眼下”(=now),用于现在进行时。如：Please wait for a moment.(请稍等)/ Let’s leave things as they are for the moment.(暂时就维持现状吧！) / I’ll come back in a moment.(我过会儿回来)/ I am very busy at the moment.(眼下我很忙)
(10)but的问题：用介词but引出另一个动词时,要注意：如果前面有do,后面就用原形动词,前面没有do时,后面的动词要加to。如：I could do nothing but wait.(我什么也做不了只能等) / They had no choice(选择) but to fight.(他们没有选择只有战斗)
(11)in front of 与in the front of： in front of“在…的前面”, 与in the front of“在…的前部”。如：A car was parking in front of the hall.(大厅跟前停着一辆汽车)/ In the front of the hall stood a big desk.(大厅前部立着一个大讲台)
(12)except与besides的区别：except“除了”,表示排除掉某人物,即不包含；而besides“除了”则表示包含,即“不仅……又……”。如：Everyone went to the Palace Museum except Tom.(除了Tom,大家都去了故宫博物院)(Tom没有去故宫)/ Besides Chinese he also studied many other subjects.(除了汉语之外,他还学其他许多功课)(“汉语”也是他学的功课之一)

★重要注解：
(1) 关于实义动词：
① 英语的实义动词又可分为及物动词和不及物动词两大类：
后面必须跟宾语意义才完整的叫及物动词；本身意义完整,后面不需跟宾语的叫不及物动词。
② 有些动词通常只作不及物动词。如：go,come,happen,lie,listen,rise,arrive,hall等。
有些动词通常用作及物动词。如：say, raise, lay, find, buy等。
③ 大多数动词可以兼作及物动词和不及物动词。如：study, sing等。
④ 有些动词作及物动词与作不及物动词时的意义有所不同。如：know, wash等。
⑤ 有些动词常和介词 、副词或其它词类一起构成固定词组,形成短语动词。如：listen,reply,wait,look.
(2) 关于连系动词：
① 连系动词用来连接主语和表语,连系动词后面常为形容词。
② 常见的连系动词有：be、become、look、feel、sound、smell、taste、seem、turn、grow、get、 go、fall、sit、stand、lie 等。
③ 有些连系动词来源于实义动词,意思也跟着变化：look(看→看起来)、feel(感觉、摸→感到)、 smell(闻、嗅→闻起来)、taste(尝→尝起来)、turn(翻转、转动→变得)、grow(生长→变得)、get(得到、到达→变得)、go(去→变得),所不同的是,作为实义动词时,后面不能跟形容词。
[注释]
become、get、go、be、grow、turn的用法区别：become表示“变成”,比较正式,通常不用将来时表示动作已经完成。get也表示动作已经完成,但是更加口语化,通常表示温度、时间、岁数等变化。go表示“变得”,常见于某些短语中,后面常有形容词bad、blind、hungry等。be表示“是、成为、当”,多用于将来时、祈使句或不定式中。grow表示“变得”,常指逐渐的变化,表示身高、岁数的增长。turn表示“变得”,指变为与原先不同的情况,通常指颜色等变化。如：I was caught in the rain and I became ill.(我淋雨感冒了)/ He has got rich.(他变富了)/ He will be a scientist in the future.(将来他将成为科学家)/ My little brother has grown much taller in the past year.(在过去的一年里我的弟弟长得高多了)/ The sandwich has gone bad.(那块三明治已经变坏)/ Her face turned red after her mother criticized(批评) her.(妈妈批评了他以后他的脸变红了)
(3) 关于助动词：
①常见的助动词有：用于进行时和被动语态的be (am, is, are ,was, were, been, being ) ;用于完成时的have(has,had,having) ;用于将来时的shall (should) ; will (would)和用于一般时的do(does,did) .
②助动词必须同主语的人称和数一致,也就是说因主语人称、数的不同而采用不同的形式,其中有些助动词也可作情态动词。如：shall, will, should, would.
(4) 关于情态动词：
①常见的情态动词有：can (could) ,may (might), must ,shall (should), will (would), dare (dared) , need等,另外,have to、had better也当作情态动词使用。情态动词后面必须加动词的原形。
②can表示体力、脑力方面的能力或客观的可能性。口语中, 在询问或说明一件事可不可以做时,常用“can”代替“may”。情态动词“can”的过去式是“could”,否定式是“cannot”通常缩写成“can’t”,“could”的否定式是“could not”,通常缩写成“couldn’t”。如：Can I help you?(要帮忙吗？)/ He can swim.(他会游泳)/ That can’t be Mr Li.(那不可能是李先生)
③ may表示允许、请求或可能性,用may提问时,肯定回答一般用Certainly或Yes,you may.;否定回答一般用can’t或mustn’t. 如：May I ask you a question?—Certainly.(可以问你一个问题吗？当然可以)/ You may go now.(现在你可以走了)/ It may be in your pocket.(它可能在你的衣袋里)
④ must表示“必须”、“一定”的意思。表示“必须”时否定形式是mustn’t；表示“一定”时,否定形式是“can’t” 如：We must be very careful when we cross the road.(我们过马路时一定要非常小心)/ It must be Jack.(那准是杰克)/ I haven’t seen Kate today. She can’t be here.(我今天没有看到过凯特,她不可能在这里)
[注意]用must(必须)进行提问时,肯定回答用must,否定回答用needn’t；用must(一定)进行提问时,肯定回答仍用must,但是否定回答用can’t.如：Must we clean the room before we leave? –Yes,you must.或No,you needn’t.(我们走之前必须要打扫房间吗？是的,必须打扫。/ 不,不需要。) / Must she be in the romm? –Yes,she must.或No,she can’t.(她一定在房间里吗？是的,一定。/ 不,不可能在。)
⑤ “have to”表示“不得不”、“必须”。We’ll have to leave now for it is very late at night.
have to的疑问形式是：助动词+…+have to,否定形式是：助动词+not+have to或者用needn’t.如：Do you have to stay until 8 o’clock?(你得呆到8点钟吗？)/ You don’t have to do so.(=You needn’t do so.)(你不用这么做)
⑥ shall在问句中,可表示征求对方意见,与第一人称连用；在陈述句的第二、三人称的主语后或表示“命令”、“警告”、“允许”等。如：Shall we go to the zoo this weekend?(我们这个周末去动物园好吗？)/ He shall bring his own book next time.(他下次必须带自己的书来)
⑦ should可表示“劝告”、“建议”、“惊奇”等意思。We should speak to old people politely.(我们应该礼貌地对老人讲话)
⑧ will表示“意愿”、“决心”等意思,一般与第二人称连用。如：Will you please close the door for me?(请你替我把门关上好吗？)/ I will teach you a lesson.(我要教训你一顿)
⑨would表示过去的“意愿”、“决心”等。He would sit near the fire every time he returned home.(每次他回到家中总要坐在火炉边)
would也可以表示现在的情况,表达说话人向对方提出的要求,语气比“will”婉转、客气。在日常会话中,“我想要…”通常用“I would like to”或“I should(I’d) like to”来表示。如：Would you like to have a rest at the moment?(你现在想要休息一下吗？)
would还可以表示过去经常发生的事情。如：Every year parents would tell their children about the boy who would save his people.(每一年父母们总是向孩子们讲述这个将会拯救他的人民的男孩的事)
⑩ need表示“需要”,用于疑问句或否定句。“need”作实义动词时,在肯定、否定、疑问句中都可以用。如：He needn’t do it in such a hurry.(他不需要如此匆忙地做这件事)/ He needs some help.(他需要一些帮助)/ He doesn’t need to bring his football socks then.(那么他就无须带上足球袜了)
⑾ dare是“敢”的意思,用法几乎与“need”完全相同,即在疑问句和否定句中,可以作情态动词,后面用不带“to”的动词不定式。在肯定句中和实义动词一样,后面的动词不定式要带“to”。How dare you say I am a fool?(你竟敢说我是个傻瓜？)/ He didn’t dare to touch the red button.(他不敢触碰那个红色的按钮)
⑿ ‘d better (do)(“最好是”)一般也当作情态动词使用,否定式是：’d better not (do). 如：You’d better sit here and say nothing.(你最好坐在这儿不讲话)/ You’d better not speak because he is sleeping.(你最好不要讲话因为他正在睡觉)

+动词-ing were | would + 动词原形
+going to+动词原形 were | had +过去分词 |
| 瞬间性动词的完成时 | → | 延续性动词或状态动词的完成时 | ||||
