[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。) ? 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。)
? 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。
? 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。)
? 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)
? 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。)
? 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！)
? 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。) ? 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)
? 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.
⑴“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)
⑵ 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？)
⑶ 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)
⑷ 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)
⑸ 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)
⑹ 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。) ⑺ 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)
⑻ 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)
⑼ 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。
⑽ 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 good好的 well好；(身体)好的, bad,badly糟糕的,糟糕地 ill(身体)不舒服的 many许多的(可数) much许多的(不可数)；非常 little少的 far远的；远地 比较级 better更好的 最高级 best最好的 worse更糟糕的,更糟糕地；worst最糟糕的,最糟糕地；(身体)更不舒服的 (身体)最不舒服的 more更多的；更 less更少的 farther更远的；更远地 further进一步的(地) most最多的；最 least最少的 farthest最远的；最远地 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。) 七、介词：
