What is an issue of "sentence structure"?
Things that are supposed to be sentences but AREN'T sentences.
*Fragments
My brother.
My friend,who lives in Texas.
*Run-on sentences("too many ingredients"for a single sentence)
My friend lives in Texas,he enjoys the hot weather.
My friend, who lives in Texas, he enjoys the hot weather.
2 goals:
-Understand these sentence structure errors.
-Be able to IDENTIFY these errors WHEN YOU ARE LOOKING AT A PROBLEM.
Although ice particles in the upper atmosphere benefit Earth in that they reflect and absorb solar radiation, acting as a global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate the destruction of the ozone layer by reacting with chlorofluorocarbons (CFC's).
(A) acting as a global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate
(B) acting as a global thermostat and thus keeping Earth either from burning up or freezing over, while also accelerating another modifier---No sentence
(C) act as a global thermostat and thus keep Earth from either burning up or freezing over, while also accelerate
(D) they act as a global thermostat that thus keeps Earth either from burning up or freezing over, even though it also accelerates
(E) they act as a global thermostat to thus keep Earth from either burning up or freezing over, but they also accelerate
第一步 从句意判断转折关系
What are the ideas in this sentence?
1)Ice particles benefit Earth by doing stuff with radiation
2)The act as a global thermostat---they prevent freeze-over and burning.
*BUT* 并不是说一定要加but,只代表着相反的意思,前面已经用了although,后面不能再用but
3)The accelerate the destruction of the ozone layer.
第二步Remember how "Although" works(USE YOUR OWN EXAMPLES if necessary)
Eg. Although I left home early, I still go to work late. ------ this would be a complete sentence
Consider the MEANING of a sentence with Although
Although I Left home early, I still got to work late. contrast
分析以下:
B. Although I left home early, still getting to work late.
C. Although I left home early, still got to work late.
第三步 发现pronounce错误
D. tries to use "IT"to stand "ice particles" Not OK---plural.
第四步 判断modifiers and essential parts---overall sentence construction
E. Subject1+verb1, subject2+verb2 ----run-on
再从modifiers上看一遍:
Although ice particles in the upper atmosphere benefit Earth in that they reflect and absorb solar radiation, acting as a global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate the destruction of the ozone layer by reacting with chlorofluorocarbons (CFC's).
(A) acting as a global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate
(B) acting as a global thermostat and thus keeping Earth either from burning up or freezing over, while also accelerating
(C) act as a global thermostat and thus keep Earth from either burning up or freezing over, while also accelerate 不算真正意义上的modifiers
(D) they act as a global thermostat that thus keeps Earth either from burning up or freezing over, even though it also accelerates
(E) they act as a global thermostat to thus keep Earth from either burning up or freezing over, but they also accelerate
以上绿色为modifiers,蓝色为essential parts。
其余知识点:
知识介绍:
What's in this split?
*Modifiers=neither subject nor verb
*Verb
*Subject+verb
How do we RESOLVE a split like this?
What happens if a modifier is replaced by a subject+verb, or by a verb?
Consider:My friend lives in Texas. ---complete sentence
My friend,who lives in Texas.----not a complete sentence(no main verb)
Modifiers can be eliminated are replaced by elements that CAN'T BE ELIMINATED.
consider the effect on the OVERALL STRUCTURE of the sentence.
Look out for run-ons and fragments.
eg. My friend is a sales manager who lives in Texas. ----complete sentence
My friend is a sales manager lives in Texas. ------run - on (tries to have 2 verbs)
避免受到Spoken language的影响
*DON'T pick a choice because it "sounds good"
BUT
*Don't ELIMINATE a choice because it "sounds good",either.
BUT 是否不能与Although同时出现在同一个句子中:
Specific answer: Sure...if it makes sense.
general advice:
Don't try to memorize entire sentence structures as "right"or "Wrong"!!
You WILL have to THINK ABOUT THE MESSAGE of a sentence to evaluate whether things like "although", "but", etc, actually make
例2:Emily Dickinson’s letters to Susan Huntington Dickinson were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumbering her letters to anyone else.
(A) Dickinson were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumbering
(B) Dickinson were written over a period that begins a few years before Susan’s marriage to Emily’s brother and ended shortly before Emily’s death in 1886, outnumber
(C) Dickinson, written over a period beginning a few years before Susan’s marriage to Emily’s brother and that ends shortly before Emily’s death in 1886 and outnumbering
(D) Dickinson, which were written over a period beginning a few years before Susan’s marriage to Emily’s brother, ending shortly before Emily’s death in 1886, and outnumbering
(E) Dickinson, which were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumber
HINT: Split between MODIFIERS& CORE ELEMENTS(subject/verb)
以上蓝色部分为essential elements,红色部分为modifiers。
Essential elements多了就是add too many things in one sentence----Run-on 例如B
(b)has two blue things.(two verbs)
eg. My friend is a sales manager lives in Texas.
Modifiers 多了可能会出现Fragment.例如C,D
(c)and (d)lack verbs altogether:
eg. My friend, who is a sales manager and lives in Texas.
(b)(c)also have clear non-parallelism
剩余A,E当中如何选择呢?从Grammar上看都是acceptable的,但是从Meaning上看呢?
BRIEF DISCUSSION OF "COMMA+-ING"
---it should describe the whole idea of the preceding clause in some way.
* Immediate result
Eg. I fall in love with Mike, losing my mind under this relationship.
* Ways in which the preceding statement works or is true
* More specific description of the preceding statement
比较以下两句话:
Stuart is one of the highest-achieving students in the class,standing almost seven feet tall. Nonsense 前面是讲achievement,后面讲身高,什么鬼!
Stuart is one of the highest-achieving students in the class,scoring at the top of scale on almost every exam. Sensible 前面讲achievement,后面把成绩爆出来,没错,lz就是比你们强。
(a)The letters were written over xxxxx time period,outnumbering her letters to anyone else.
No significant relationship to blue thing.
假设我问小明,你入伍多少年?
小明说我参军已经十年了,头衔高你好多级。然而我只想知道你到底什么时候开始的,你回答我一个别的东西,这样有意思么,诚心显摆么。
E. Stuart, who stands almost seven feet tall, is one of the highest-achieving students in the class.
这句话就好像说,看那个高高瘦瘦的男孩子,他的GMAT 成绩可棒了!一样的
