考点二 过去分词 /5f=a
1. 过去分词作定语 4%
jQHOZ
与现在分词类似,过去分词作定语常可和定语从句替换, 通常表示被动的含义. Nqj5, 9
*c
如:a theory derived from rich experience
kL -f@CD
= a theory that has been derived from rich experience T<0V ^B7
a gas composed of four chemical elements <Um 5w1
= a gas that is composed of four chemical elements !3*%-8bp
单个分词可放在被修饰词之前,如:distinguished guests, unexpected trouble :-+j,G9t
改错题中常考现在分词和过去分词的混用,关键看被修饰词和分词代表的动作是主动还是被动关系。 1=jwJv.^/
例如: boiling water (沸腾的水,表示正在沸腾); boiled water(开水, 表示已经烧开) VQ2B|v
2. 同源现在分词和过去分词做定语的区别 *.-qbwOg
有时一个动词词尾分别加上-ing和-ed就构成了一组同源现在分词和过去分词, 这样的例子在英语里很多, 如: interesting/interested, exciting/excited, disappointing/disappointed等, 这些由动词变化而来的分词已经被人们视为形容词了. 但是, 同源现在分词和过去分词做定语时有什么区别呢? *Y ?&N2@c
现在分词通常表示某个事物的特性, 通常用来修饰某事或某物, 含有“使人(令人)感到…”的意思, 如: an interesting novel, a confusing question等; 1W>0
过去分词通常表示人的感受或状态, 意思是“…的…”, 如: a worried look (焦虑的神情) @l~MY*hp
试比较: an interesting boy (一个有趣的男孩 - 让人觉得很有趣) ","to
an interested boy (一个产生了兴趣的男孩 )5s-"o<
同样, 当同源现在分词和过去分词做表语时, 在意思上也存在同样的区别, 如: U]iZ3^8VT
The results are very disappointing. (结果很让人失望) 4m_CPe
We are very disappointed at the results. (我们对这样的结果很失望) 6[]O3Aa

(C) it was chartered U{0!
<*W>
(D) to be chartered e>_Il']Mb
答案:A 9Qc=D"'
解释:本句主谓结构完整, 缺少的是主语的修饰成分, A构成过去分词短语作定语;B C 的动词结构与原句谓语冲突; D 不定式一般表示即将发生的动作, 与in 1785不符 BHIC6i%

(A) called 3rVWehCv
(B) to call uBxs`'C
(C) is called "I&,':O+
(D) call as z%[^-l-
答案:A |Ht~o(]&&/
解释:此句主谓完整, 句中又无连词, 需填的只可能是非谓语成分, A 是过去分词短语作定语, 等效于which is called, 符合题意. C D 属谓语结构, 与原句谓语冲突; B 不定式表用途或目的, 意思不通 JCZ 5q9b
3. 过去分词作状语 {~~'
过去分词也可放在句首、句中、句尾作句子的状语,常表示事件发生的背景或原因, oD7^9=#
如:Seen from far away, the islands look like a chain of pearls in the midst of the lake. 4lF?s\W:
De iig@$
i#
D=!5l4
feated in the final, the team gathered to analyze its technical disadvantages. Vi\kB%
特别注意:分词状语的逻辑主语和句子的主语要保持一致. 选择题中, 经常要求考生在分词状语部分填入合适的过去分词或现在分词. 到底选择哪种分词, 考生可以采取这样的作题方法: 首先根据“分词状语的逻辑主语和句子的主语要保持一致”的原则确定状语部分的主语, 再判断这个主语和分词是什么关系, 若是主动关系则应该用现在分词, 若是被动关系则要用过去分词. h<IPV'1

EXYLG
(B) Founding 3q:>NB<
(C) To found Vh5Z'4N
(D) Having founded g)Dg=3+

答案:A ZH8Oidj`
解释:分词部分的逻辑主语也应当是the Boston Latin School, 它和found之间是被动关系, 所以空格处应填入过去分词 J+=+0{}

答案:A $WHmG!)*
应改为:Almost destroyed ZT

解释:by是被动式的标志词, 动词destroy应用过去分词destroyed, 这样既表被动又构成句子的状语 ^h\Y.

考点三 独立主格结构 Q=Y1kcTOn
独立主格结构是介于分词和主谓句之间的非谓语形式,对于分词来讲其逻辑主语必须和句子的主语保持一致,而独立主格则在很大程度上克服了这一局限性 vK~tgZ&
1、主要特征 c6Z\ecH9
(1) 独立主格是含有主语的分词结构,分词与主语间是主谓关系, "fX9bh^
基本形式为:主语+现在分词或过去分词 <\C/;
如:his heart bleeding O[/l';i
the baby crying tX *}l|;(
the project completed w,v~
The school being over, the street was full of the students. AEr8^6
= When the school was over, the street was full of the students. dpWBY3(7a
(2)切记独立主格不等同于主谓结构, vgvJ6$#
比较:my mind wandering (独立主格); ?ta(`+"
My mind was wandering (主谓结构) H|i39XV
(3)独立主格的主语和句子主语不一致 d0MF\yxh
如:(With) His mouth filled with water, he couldn't utter a word. (独立主格) ;
&v~tD7
对于分词来讲其逻辑主语必须和句子的主语保持一致: [>N`)]fP
Filling his mouth with water, he couldn't utter a word. Q1
?09
2. 在句子中的作用 Zn]njf1x
独立主格结构通常在句中表示时间、条件,原因、伴随状态等 }HC6m{vH(
如:The film being over, we had a stroll on the nearby street. (时间) )r^)e4UI
Weather permitting, I will go fishing with my family. (条件) Yf=Puy}q
Time pressing, they had to work overtime. (原因) JTn\NSa
The leaves rustling in the breeze, I roamed on the country road. (伴随) 8kwe ._&)

(1) d} `Z| ex
----modern offices becoming more mechanized, designers are attempting to personalize them with warmer, less severe interiors. V<%eWT)x7C
(A) If ]&mN~$+C
(B) But
E,nxv+AQ
(C) With QFS5PZ
(D)Once CCQ38P@rv
答案:C ?=\&O=_ln
解释:句中主干完整, 主语是designers, 谓语是are attempting, 之后是不定式构成的宾语. 空白后 becoming 采取分词形式, modern offices是becoming的逻辑主语, 因此可确定需填入的词会与原句构成独立主格结构, 而不是从句, A B D可一次性排除, 其实此句除去空白处, 已是完整的句子, 类似句子如: The man entered the room, his hair flying in the air. Z+G.v=2q<
注意: 表示伴随状态的独立主格结构通常可以由with引导, 如本例题. 3w-0IP]<
[G/ti&Od^
第三节 动名词 SL O~
动名词是动词的特殊形式,拼写类似现在分词,用法类似名词,具有与二者均不同的特点:动名词可作动词或介词宾语(分词不行)之后可以再接宾语(名词不行),它兼备了动词和名词的功能,故称作动名词 fd<a%nSD
考点一 动名词作宾语 ?Dr K2;q
1. 许多动词不能接不定式作宾语,同时又需要动宾结构作宾语,此时动名词便可大显身手了,如:enjoy singing(喜欢唱歌), [m9Iz!E
avoid looking me in the eye bI_T\Eft
miss crashing into the tree
-J<{NF
Fancy meeting you here! (想不到在这里见到你了) 7|/Ct;oO:
常接动名词doing做宾语的动词有: |pA
enjoy, mind, delay, avoid, consider, deny, miss, escape, fancy, suggest, insist等 % >\v6ea
另外, 在一些固定用法当中, 也需要用动名词做宾语, 如: [7btoo|P]
can't help doing, it's no use doing, it's worth doing, be busy doing, feel like doing等. V4.&"0\n #
2. 有的动词既可以用动名词作宾语,也可以用不定式,两者意思区别不大, 如: like, begin, start, love, learn等, TJY
[s-
如: She began playing piano when she was five. $gv3Up"U
She began to play piano when she was five. ^z%ShmM&LZ
但是对于remember, forget, try等动词来说,接不定式和接动名词意义不同, 如: dN%*-p(
How many people remember listening to the radio broadcast, "The War of the Worlds" |*T3TsP u
(还有多少人记得听过无线广播-- The War of the Worlds) (表示已经听过了) oieJ7\h]m
I remember to listen to the radio broadcast, "The War of the Worlds" ,Y\`n7Ww
(我想起来要听广播-- The War of the Worlds) (表示还没有听过) [K=M;$
iQ
We must try to work this problem out. (我们必须尽力把这道题做出来)(表示努力,设法) ;tZ;C(;<
We can try doing it. (我们可以试着做它) (表示尝试) }^@Q9<P^E
动名词作介词宾语的情况更加普遍,详见第四章介词-介宾短语 T.}wcQf&*
例题: E<~Fi.M;\
(1) C;UqLMrOI
A mortgage enables a person to buy property without paying for it outright; thus more =sYUzYm
A B C 3!H&bOF
people are able to enjoy to own a house. Nf!g1D"U
D hn-!W;j
答案:D 0{q>'dv
应改为:owning :< d
.
解释:enjoy doing是固定用法,必须用动名词作enjoy的宾语 g5OKhL0u
2YbI."o
b
考点二 动名词作主语、定语或表语 $5]}]
和名词相仿,动名词可作句子的主语、表语或名词的定语 4!</JZX~$
如:Meeting you is my pleasure. ^c-8~r|y,
His job is driving a bus. [qL{w&R
The opening ceremony will begin in five minutes. b4R;#rm
在简单句中, 只能有一个主语和一个谓语, 考试时经常会出现在一个简单句中主语部分不全或干脆没有主语部分, 需要考生将句子补全, 这时要注意的是主语部分只能是名词短语, 动名词短语或不定式短语, 而不能是动词短语或句子, 如: $1E'0M`
例题: Lhz*o6)
(1) @fc-[pv
---- by transferring the blame to others is often called scapegoating. 1o8C4?T&
(A) Eliminate problems ;}dvc7
(B) The eliminated problems 1`Ig A0V`"
(C) Eliminating problems 3!u`PIQv
(D) Problems are eliminated 0Xw$l3@N^
答案:C TFAd
解释:此句只是主语部分不完整,可排除A,D; B与句意不符,只有C动名词词组合适,与scapegoating相呼应。注意by后面的短语表示一种方式、手段,而不是被动式的施动者 ;H4 s[#K
(2) [2P6XoI#
---- raw materials into useful products is called manufacturing. _yRD*2 !;
(A)Transform KPrH1 [VU
(B) Transforming PNs*+/-S
(C) Being transformed T!ww3d
(D) When transforming =o5|W'>`
答案:B Ntt*}|:QV<
解释:此句is之前是句子的主语,之后是谓语,空格处需要一个能接宾语raw materials的名词性结构,这正是动名词所具备的特点,因此答案非B莫属 sxn{uRF
注意:有时需要在动名词之前加上物主代词或名词,表示动名词的逻辑主语 ~Jh1$O,9o
如: Would you mind my turning off the radio? F;L8FL-
I'm rather disappointed at Helen's putting on airs at the party. SaIY-PC

K@z&G
第四节 助动词 Ii&\LJ
yu>o7ie+;Y
助动词没有独立的语义,主要作用是协助谓语动词表示时态、语态或构成疑问式、否定式等 *>h|<|T'
助动词和情态动词的共同特点是需要和其他动词搭配使用才有意义,而且句子的否定式和疑问式都可通过这两类词体现 |[)n.N65=
一、have/has (现在完成时), had (过去完成时) v&qL r+_7
这组助动词主要用来构成完成时态,形式为:have /has /had + 过去分词 aH?+^f"D
如:I haven't seen you for ages. q
-s(2C
She had mentioned this before. hXh nJ
二、be zd6F}2*6
be本身可作谓语动词,但在进行时中它是助动词,与现在分词搭配使用,缺一不可 }P'c8$
如:She's watching a football match. ,M9e *
He's looking for his favorite pet. Ew JNpecX
此外,be和过去分词搭配构成被动语态 N%F4ug@i
如:The vicar was killed in a car accident. !
nsx!M
三、do/does (一般现在时), did (一般过去时) "~
mY4WVG
此组助动词用于构成疑问式或否定式 .e5d#gE0
如:He doesn't feel like smoking at the moment. \n`/?\r.z
Did you meet the manager this morning? Z2t\4|wr:
四、will, shall, would & 'CUc/,
此组助动词用于构成将来时 THlQifA!
如:He won't be able to see you until an hour later. Z9.0#Jnu

(B) and they are always >(-A"jf
(C) always _RIlGs\.
(D) are always =Oq*9=v|
答案:D qX*xQA|ak,
解释:空格前是句子的主语,之后是过去分词短语,空格处需要补全句子的谓语,A使原句只有从句无主句;B并列句的前一个分句无谓语;arrange与color是被动关系,C是主动式,可排除;只有D助动词are恰好与arranged构成句子的谓语 2]<.m]
第五节 情态动词 rvlvk"
R
+U$;r8l
情态动词有表示能够、愿意、请求等多种意思,比助动词用法要相对复杂些,TOEFL考试中,首先要记住语法上的要点,即情态动词之后必须接动词原形 +TyN;e
常见情态动词有: #N"u 0
must, may, might, can, could, need, shall, should, ought to, will, would, dare, dared yVgC1-8i*
情态动词表示现在对过去发生的事的猜测、想法时应该用 (情态动词 + 完成时动词),表示“应当已经 / 一直……”,“想必已经 / 一直……”。使用不同的情态动词,存在着语气、意思上的区别。 ="5D}%
must + 完成时动词:表示对过去事情的肯定性推测,意思为“一定”,“必定”。 ^vPsp?
It's ten o'clock now, they must have arrive in Beijing. 5.*,IedY
(现在10点了,他们肯定已经到了北京。) -pIz-*
He is quite tired, he must have been overworking last night. uorX;yekC
(他太累了,准是昨晚加班了。) P6O\\,B1A
may/might /can/could + 完成时动词 f9 \$,7F
(1) 均表示不肯定的推测,注意与must 肯定语气的比较。 A.Wf6o
He is so depressed, I'm afraid that he might have failed in the test. K2yu}F ^}
(他心情这么沮丧,恐怕考试没有过。) pY@QR?
F\
(2) 另外表示责备“本来可以(而竟没有)之意。 oOaFA+0x
(3)注意cannot / couldn't + 完成时动词,表示对过去事情进行肯定性的否定推测,意思为“不可能干/做”,“肯定没有做……”。 lOp.c
U
He couldn't have finished the homework in such a short time. +C8O"
他不可能在如此短的时间内作完家庭作业。 Y X^c}t}U
should / shouldn't / ought to / ought not to + 完成时动词: bY2R/FNL=
用于表示与过去事实相反的虚拟语气,意思为“应该做而未做 / 不应该做却做了”(参考“虚拟语气”章节) F_(~b
I should have brought the wallet with me. 我该带上钱包的。 e`s
1z|h
He oughtn't to have been complaining about such a trivial matter. 他不应该为这件小事而抱怨不休。 u\Ylo.)b
needn't + 完成时动词;表示做了不必要的事,意思是“原本不必”。注意与cannot / couldn't + 完成时动词 进行比较。
M2 |!,2
You needn't have told him the matter. 你其实不必告诉他这件事。 = V2Rq(jH
You couldn't have told him the matter. 你不可能把这件事告诉他了。 Ga5*tWj
区别于 would + 动词完成时,用于与过去事实相反的虚拟语气,表示对过去事情的假设。(参考“虚拟语气”章节) ;_vhKU)%J#

不定代词的用法区别在TOEFL中经常出现,这些区别对许多同学来讲比较容易混淆 {B=64,D^7R
一、比较both 和All Wv3p!zW3I
Both,either, neither都是在谈到两个人或者东西的时候用到 c-zW
2;|61
Both of them are right. (他们两个人都对) B$c'^

You can take either book.(两本书你可以任意挑一本) H1~9f{
Neither of them is going to get haircut. (他们俩谁也不愿意理发) e8SAjl"}

None of them is going to get haircut. (them指三个人以上) Nba1!5:M
I like any of them. (them指三个人以上) pb<eg,
二、None 和no R(>
oyxA[F
None和no都用于否定的意思。但是None是“没有一个人或者没有一个东西”,在句子中可以用作主语、宾语、同位语等。而No是“没有”的意思,只能够当作形容词用,不能够作代词用。 vzAY+EEx
None of them knew how to do it. (不能够说no of them) xxGQXW
No women are allowed to come in. O&CY9

三、another, the other, others, the others 7F]oK0l_
1.在涉及到两个人或者东西的时候,任意取一个用one, 另外那个用the other(表示特指) 1=_?Wg:
I have two computers; one is IBM, the other is Dell. 1.2qh"#
2.涉及到三个以上时,任意取一个用one, 泛指另外一个用another O?#<kmd/)
Three people went to the meeting. One was a software programmer, another was a network expert, and the third was a college student. {JQV~rfh`
3.涉及到三个以上时,任意取一个用one, 表示特指其他的那些用the others或者用 UM1h[#?&V)

第七章简单句 GOCe&?
J"eE9FLM
只包含一个主谓结构(一个主语+一个谓语)的句子称作简单句,是英文句子的基本形式。麻雀虽小,五脏俱全,简单句同样可以包括主语、谓语、宾语、状语、同位语等多种成分 .4z_ohe
P1qnU
第一节 主谓结构 wx/*un%2
)"bP]t^_
考点一 一般主谓结构考法 N,ihQB5
1. 主谓结构可谓是句子的核心与灵魂,完整的句子不能缺少主谓结构,即主语+谓语。 uw&p)
2. 填空题中大量涉及句子的主谓结构,这不仅适用于简单句,并列句和复合句也是同样的道理,无论是并列分句、主句还是从句都需要主语和谓语。 2reQd47
解题的步骤: 要求首先确定句子的主谓结构,根据缺少的成分对选项进行排除和筛选 J.,7d ,
例题: Ap(>mUs!i
(1) -
[vH4~
Traditionally, ----in New England on Thanksgiving Day. om0g'Qa
(A) when served is sweet cider =eeZtj.
(B) when sweet cider is served h"$],=
(C) is served sweet cider I|P#|0< 2
(D) sweet cider is served )O6_9f_
答案:D G8CM
解释:此句只给出时间和地点状语, 需填入完整的主语和谓语作为句子的主干, A B 只有when引导的从句没有主句; C 上来就是is, 没有主语; D 由名词词组sweet cider和serve的被动式构成主谓语, 使原句成为一个简单句 &(X-b"2
(2) $@ZrGT
A historical novel may do more than mirror history; ----future events. vy5SBiK
(A) even influencing ;LFs.Jc<
(B) it may even influence X=X
(C) may even influence R|t.JoP9
(D) that it may even influence $tca:
b}Mk
答案:B ":Ll.=!
解释:分号可以连接两个语义并列的完整句子, 此句需填入一个主谓结构, 从而使分号后的句子完整. A不能作谓语, 且缺主语; C缺主语; D 构成从句, 无法与分号前的句子并列 OR-fC
3. 主语多由名词充当,还可能是代词、动名词、不定式等 mRD '@n
如:He ran away. (此句中代词he是主语,ran away是谓语) e_t""h4D
有的题目选项中无明显的主谓结构,往往需要考虑there be句式,严格的讲there be是倒装句,但由于它是固定句式,可视为主谓结构 J*r%b+
如:There are a lot of monkeys in the zoo CoQ<Ky}*
5|bc*iqU
考点二 谓语动词 47^R
1. 主谓结构十分重要,谓语动词则是要点中的要点,国不可一日无君,句子不可缺少谓语动词。象祈使句可以没有主语,但却少不了谓语动词。 !:<n]
-U
2. 一个句子当中可能出现多个动词形式,却未必而且往往不都是谓语动词,必须掌握确定谓语动词的方法,才能从容解题。 #bdSH)V
一般说来能够决定句子的时态、语态、语气的词就是谓语动词,如:studies, was known, is reading, has achieved, must be, can make等形式的动词肯定是谓语;单独的分词、不定式都属于非谓语形式,如:broken, ringing, to look after }>~]q)]
例句: Having thought for a while, she decided to forgive the man caught stealing her diamond. Jhr3[A
此句中有四个动词结构,但只有decided是谓语形式,其他分别为分词作状语(having thought)、不定式作宾语(to forgive)、分词作定语(caught stealing) o"e]9{+<
3. 谓语专一原则 fg0zD:@rA
(1) 简单句中只允许存在一个谓语动词,其余动词必须是非谓语形式,如上面的例句。 tG(!d$^
英文中切忌:两个谓语形式的动词直接连接(尤其是be动词不能和实意动词连用,is do是绝不可能出现的),或以逗号连接 HD{2nZT
(2) 确实需要多个谓语时需用连词, 或主从句形式加以连接(分号也可) {G4{4D }
如: She looked and smiled. &!
MV!9$
He will give you some advice; he may even help you do it. $"6O92G(hJ
(3) 值得注意的是并列句中的每个分句及主从句中的每个简单句仍需遵循谓语专一原则。 gOKF%Ej31T
牢记这一原则才可准确地排除干扰选项,找出句中的致命错误 +*ZF52hy|

A B C D

(B) to have |;k@Zlvc
(C) having $F/Uk;*d!
(D) has Vp
j[)W%L
答案:D \GEf,%U<K
解释:此句已给出主语和由定语从句修饰的宾语,缺少谓语动词,只有D可单独作谓语 5}MjS$2og
考点三 表语 bL9vjD'}
系动词be作谓语时,与之搭配的部分被称作表语,表语多由形容词、名词担当,也可是介宾短语、不定式、分词或动名词等 C])b 3tM,7
如:He is a doctor. 1sN >U<

(C) are starlike objects !aQQq[
(D) are they starlike objects Ia!B8$$'RP
答案:C |fhYf

解释:此句缺少谓语,C由系表结构组成,原句中的分词短语恰好作表语的定语。A B 与原句主语冲突,也不符合同位语的要求;D中they和starlike objects重复 @=G6fW:
(2) ;r.0=Uo9]

(A) abundant 3tu:Vc.:M
(B) the abundance l`k""f69W
(C) an abundant A4
(D) it abundant OuuN~yC
答案:A Iq["(!7E5
解释:空格处需要is的表语,B不可数名词abundance之前不应加the;C少名词;D多代词it; A形容词,恰好作表语 5g\>x;cc
N&jHU+{OU
第二节 状语 EPu-oE=HW4
uZhY)o*]@
句子中除了主谓结构外,还可能包含表示时间、地点、方式等内容的状语,通常由副词、介宾短语来承当。 c[<>e#s+;
如:At night, I don't go out very often., 此句中at night, very often都是状语 &8x
wR
介宾短语作状语是填空题的重要考点,若空格处或空格所在部分之后是完整的主谓句,且两部分之间多以逗号隔开,若选项中无从句结构或分词,此时空格处需填入介宾短语作状语。 OLs<]0H

(A) Its } 8&?
(B) Where its TnXx;v
(C) Since its >O$JS,
(D) Because of its ]TX"BH"2
答案:D wS+ekt5
解释:此句主干完整, 主语是the use of phenol as a general antiseptic, 谓语是has been largely discontinued, 逗号之前应是状语. A构成名词短语, 与该句主语发生冲突; B、C欲构成从句, 但缺少从句的谓语动词; D恰好构成表示原因的状语, 短语because of 之后常接名词或动名词表原因, 如: He failed the exam because of his carelessness. hSgH;k
