1、Preliminaries:1. Why sentence b cannot replace sentence a? a. Mary is poor but John is happy. b. ?*Although Mary is poor, John is happy. 2. What do coordination and subordination means? Illustrate the terms with exemplifications. Coordination Subordination Coordination A coordination is a sequence o

2、f semantically-related grammatical units that are similar in form, equal in rank of structure, identical in function and are connected by coordinators, e.g.husband and wife, up and downgood but expensive, brave but foolishstay or leave, to be or not to beNotes:Coordination may be on different level

3、of structures (words, phrases, or clauses)Coordinating devices may include coordinators and punctuation marks.CoordinatorsModern English has three basic coordinators: and, or, but. Added to these are yet, so, nor, items that can function both as conjunctions and as conjunctive adverbs. In addition,

4、there are some correlative coordinators semantically related to the basic coordinators such as bothand, not only but also, not nor, neither nor, either or, etc.There are also quasi-coordinators such as well as, as much as, rather than, more than, etc. ranking between a coordinators and a subordinato

5、r or complex preposition.Finally, for can be a either as a coordinator or as a subordinator. In our course book, for is treated as a subordinator, introducing an adverbial clause of cause, like because.Coordinators Semantically considered, English coordinators can be roughly divided into three types

6、: And-group coordinators addition Or-group coordinators alternation But-group coordinators contrast/transferAnd-group coordinatorsObserve the following examples involving semantic extension via coordinators: and, both and, not only (but) also, not nor, neither nor.As is reported, a trade agreement w

7、as signed, and a cultural exchange was arranged.Mrs Cox is both kind and gentle to her pupils.He not only wanted the diamond but wanted it desperately.Jane will never compromise with Bill, nor will Bill compromise with Jane. He has neither phoned nor written us recently.And-group coordinators But: H

8、e is nice and gentle. Ill go and bring back your boots. You must try and persuade her to come. Can you touch pitch and not be defiled? nicely / verygo totry towithout being defiledAnd-group coordinatorsNote that besides “addition”, coordinator and also carries some other senses, e.g.He is Jack of al

9、l trades and master of none.He took a cigarette and handed it to a stranger.Turn left at the first crossing and youll see the school.Mary likes music and Jim is fond of sports.He is a bit barbaric, and I dont like this. transfertemporal sequencecondition & resultcontrastAttitudinal disjunctOr-group

10、coordinators This group includes or and eitheror, denoting “alternation”. But it is worth noting that they can also denote negative condition e.g. Make up your mind, or you will miss the chance. Youll either behave yourself, or youll never go out to play. *Both Jane wanted to go to the south, and he

11、r husband wanted to go there, too. *He both like music and sports. *He not only likes music but also sports. *He both likes music and he likes sports. *He not only likes music but he also like sports.Observe the unacceptable sentences below, transform them into grammatical forms:But-group coordinato

12、rs This group includes but, notbut, while, whereas, yet, only, etc. denoting “contrast or a turn in meaning, e.g. This coat is not mine but yours. It never rains but it pours. She is a funny girl, yet you cant help liking her. I often dream of buying a big house in Guangzhou, only I cannot afford it

13、.Subordination A grammatical unit that functions as a constituent of another unit of equal or lower rank of structure is called a subordinate construction. Subordinate construction can be a finite clause, a non-finite clause, a verbless clause or a phrase. Subordinate clauses are generally introduce

14、d by subordinators, which in terms of word formation, can be classified into (P346-347):simple subordinators (e.g. when, before, thoughetc.)complex subordinators (e.g. now that, such thatetc.) correlative subordinators (e.g. no sooner than, etc.)marginal subordinators (e.g. on the grounds that)The r

15、ain stopped, and the sun came out.When the rain stopped, the sun came out.Coordination and subordination are two devices for combining and relating ideas. Generally speaking, coordination establishes a relationship between ideas of approximately equal importance, while subordination establishes a ki

16、nd of relationship which indicates that one idea is more important than the other.Observe the pair of sentences below:It is a general practice to put the main idea in the matrix clause and the minor idea in a dependent clause. Subordinate ideas can be expressed through finite or nonfinite clauses or

17、 by a verbless clause, e.g.As they were curious about their new neighbors, the Johnsons went and visited them at the first opportunity.Being curious about their new neighbors, the Johnsons Curious about their new neighbors, the Johnsons With curiosity, the Johnsons Ways of subordinating minor ideasS

18、yntactically, subordinate clauses can be subdivided into three types:nominal clause perform the functions of nouns, introduced by that or wh-word such as: who, what, which, whether, where, when, how, why, etc. relative clause perform the function of adjectives, introduced by relative pronouns and re

19、lative adverb (we will return to this in next lecture) adverbial clause perform the function of adverbs, denoting time, place, manner, cause, result, purpose, condition and concession, etc.Subordinate clauses (finite) You must give it back to whoever it belongs to. My first question, why he was late

20、, has not yet been answered. The question is whether he ever went there alone. I cant imagine what made him so popular among the youngsters. It is quite clear that the crime was done deliberately. What caused the fire is still a mystery. Tell the syntactic functions of the nominal clauses:object of

21、prep.appositionSubj. complementobjectsubjectsubject When/Whenever he goes to town, he always visits his aunt. She felt ill when/whenever she ate oyster (牡蛎). He cooked while I read the paper. He was cooking while I was reading the paper. He worked as long as we played.Observe the adverbial clauses o

22、f time, pay attention to their temporal features:same time, habitual, = if/every timeBoth actions are durative, happen at the same period of time,emphasizing equal length of time The dog barked when it heard a noise. The instant he saw her, he recognized her. Let me know as soon as you arrive. Hardl

23、y had I left the room when they began to quarrel. No sooner had I left the room than it collapsed.Observe the adverbial clauses of time, pay attention to their temporal features:Two simultaneous short action, I broke a glass while I was cooking the dinner. I was cooking the dinner when I broke a gla

24、ss. = , and at that time I broke a glass I met Marry as I was going home. I was going home when I met Marry. =, and at that time I met MarryObserve the adverbial clauses of time, which action lasted longer?One action happens in the process of another.One action happens in the process of another.

25、er he painted the windows, he painted the doors. When he had painted the windows, he painted the doors. He didnt paint the doors until after he had painted the windows. When I reached the station, the train had left. The train had left before I reached the station. I reached station after the train

26、had left.Observe the adverbial clauses of time, which action takes place earlier or later? We hurried because / for it was getting dark. It must be very late because / for the streets are quite deserted. In denoting direct reason, because and for are interchangeable, but in current speech because is

27、 preferable to for which is commonly used in formal style and sounds more or less bookish. Observe the adverbial clauses of cause:A because-clause can appear either before or after the main clause, whereas a for-clause can only follow rather than precede the main clause.A because-clause can stand al

28、one as a response to a why-question, while a for-clause cannot.Because can be negated by not or be modified by an adverb. It also admits coordination like “not because but because”, while for cannot be used in this way.A because-clause can function as the focal element of a cleft sentence, where for

29、-clause cannot. The differences between because & for:For example:John failed the exam, because / for he did not study hard.Because /*For he did not study hard, John failed the exam.It is because /*for he did not study hard that John failed the exam. Why did John failed the exam? Because / *For he d

30、id not study hard. The differences between because & for:Note: for can also be a coordinator, introducing an independent clause of cause, whereas because is always a subordinator, only introducing a dependent clause which cannot stand alone unless it is used to answer a why-question, e.g.When I saw

31、her in the river, I was frightened. For / *Because at that point the currents were dangerous.The differences between because & for:Among because, since and as, because is the strongest in tone; since ranks next, and as next to since. When used to denote cause, because supplies new information. There

32、fore, a because-clause can be used as an answer to why-question and as the focal element of a cleft sentence. Since and as express the information already known to the listener. because, since, asI dislike those luxurious hotels, not because I cannot afford the expenses, but because I dont think it

33、deserves the price they ask. Since China has a population as huge as 1.3 billion, a very small problem in China, if multiplied by 1.3 billion, will turn out to be extremely serious.In order to prevent the pollution from reaching the point of no return, lets take actions from ourselves to protect our
