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.

原级

比较级 最高级

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 3、不规则变化:

better更好的 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 more更多的;更 less更少的 farther更远的;更远地 further进一步的(地) (身体)最不舒服的 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:

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。

方向(目标趋向)介词:across横越..., against对抗..., along沿着..., around绕着..., round

环绕..., at朝着..., behind向…后面, etween…and…从…到...,by路过/通过..., down向…下, for向..., from从/离..., in进入..., into进入..., inside到...里面, near接近..., off脱离/除..., on向...上, out of向...外, outside向....外, over跨过..., past经过/超过..., through穿过..., to向/朝..., towards朝着..., on to到...上面, onto到...上面, up向...上, away from远离...

时间介词:about大约..., after在…以后, at在… (时刻), before在…以前, by到…为止,

during在…期间, for有…(之久), from从…(时)起, in在(上/下午);在(多久)以后, on在(某日), past过了…(时), since自从…(至今), through 贯穿…(期间), till直到…时, until直到…时, to到(下一时刻), ever since从那时起至今,at the beginning of在...开始时 ,at the end of在...末 , in the middle of在...当中 ,at the time of在...时

方式介词:as作为/当作..., by用/由/乘坐/被..., in用…(语言), like与…一样, on骑(车)/

徒(步),通过(收音机/电视机), over通过(收音机), through通过..., with用(材料),用(手/脚/耳/眼), without没有…

涉及介词: about关于..., except除了…, besides除了…还... for对于/就…而言, in

在…(方面), of…的,有关..., on关于/有关..., to对…而言, towards针对..., with就…而言 其它介词:

【目的介词】 for为了..., from防止…, to为了…

【原因介词】 for因为..., with由于…, because of因为...

【比较介词】 as与…一样,like象…一样,than比...,to与…相比, unlike与…不同 【伴随/状态介词】 against和…一起(比赛),at在(上班/休息/上学/家,etc.),in穿着…(衣服/颜色),into变成...,on在(值日), with与…一起,有/带着/长着..., without没有/无/不与…一起

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 .(状)(那个人走下楼来)/The woman 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:

? 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) ? 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) ? 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) ? 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…
