  1. Essential grammar Week 6 – Clauses Participial phrases By Peiling Hsia

  2. Contents: • A quick review of relative clauses • Adverb Clause - Time Clause • Participial phrases • Reducing dependent clauses

  3. A quick review of relative clause 由關係代名詞所引導的子句 基本核心就是在處理 如何避免名詞重覆 There are now three options for direct flights between Vancouver and Hong Kong, and the three options mean finding bargain airfares is much easier. There are now three options for direct flights between Vancouver and Hong Kong, which means finding bargain airfares is much easier.

  4. 排列的次序問題 There are now three options for direct flights between Vancouver and Hong Kong, which means finding bargain airfares is much easier. 如果說含有關係子句的主要子句是個簡單不複雜的句子,如 “He tore up my photo, which upset me.” 是很容易安排次序。 如果主詞出現了4個直接、間接的形容詞來修飾,就會產生排序問題。 • 4 message units: (1) there are now three options (2) for direct flights (3) between Vancouver and Hong Kong (4) which means finding bargain airfares is much easier

  5. Message unit 位置分配原則是: 1. 主要資訊 - 一定是句子核心 (core) 2. 補語 受詞或主要相關資訊 優先於修飾語 3. 修飾語間,有其約定俗成的優先次序 : - 地點, 時間 - 數量, 大小, 顏色其它修飾等 4. 會讓人產生ambiguity部份優先

  6. (1) there are now three options (2) for direct flights (3) between Vancouver and Hong Kong (4) which means finding bargain airfares is much easier • 4 message units: 1423 : There are now three options, which means finding bargain airfares is much easier, for direct flights between Vancouver and Hong Kong. 1243: There are now three options for direct flights, which means finding bargain airfares is much easier between Vancouver and Hong Kong. 1324 : There are now three options between Vancouver and Hong Kong for direct flights, which means finding bargain airfares is much easier. 1234: There are now three options for direct flights between Vancouver and Hong Kong, which means finding bargain airfares is much easier.

  7. Adverb clauses - Time Clauses • Adverb clause is dependent/subordinate clause that acts as “adverb”. http://esl.about.com/library/grammar/blgr_adverbclauses_time.htm

  8. Adverb – it modifies adjective, verb, and adverb.It tells us: When Where How Let’s clean the garage on Sunday. I ate my lunch at a nice restaurant. we waited patiently.

  9. Clause: Adjective clause Adverb clause – provides information for a noun. – tells us when, where, how, why. 7 common conjunctive adverbs used in adverb clause: when, while, where, as, since, if, although

  10. Example: Adverb clause – it is a group of words with a subject and a verb, and it is acting as an “adverb”. It modifies verb, adjective, adverb, entire clause. • Today is an adverb modifying • the verb walked. It is telling us • when I walked. A whole clause is modifying the verb walked. It is still telling us when I walked. I walked today. I walked before the sun went down.

  11. Adverb clause = dependent clause I listen music until I fall asleep. Whenever my teacher yells, I know she’s having a bad day. I will take out the trash after I walk the dog. Until I fall asleep Whenever my teacher yells After I walk the dog

  12. When an adverb clause begins the sentence use a comma to separate the two clauses. When the adverb clause finishes the sentence there is no need for a comma. As soon as he arrives, we will have some lunch. He gave me a call when he arrived in town.

  13. Time Clauses = Using adverb clauses with time expressions Time clauses and phrases help show the continuity of development in a process. The most common time words used to introduce time clauses are: before, after, when, while, as, and until.

  14. Examples: • Autumn is the season. The leaves of many trees change color during the season. • 2. Thanksgiving is a holiday. Families like to gather together on the holiday. Autumn is the season when the leaves of many trees change color. Thanksgiving is a holiday when families like to gather together.

  15. Types of time clause: • Simultaneous action • Sequential action • Participial phrases

  17. Time clauses2. Sequential action • ________the eggs have thickened, serve them with toast. • The eggs must have thicken ______ you serve them. • Do not serve the eggs ______ they have thickened.

Just take whatever you want. = please give it to any who needs it. Say hello to any whom you meet. Take any that you like. Take any that you want.

  30. Participial Phrases分詞片語

  31. Participle - a word formed from a verb and used as an adjective to modify nouns. A participle often appears with additional words that adds details to it. Present participle: V - ing Past participle: V –ed

  32. Together, the participle and the additional words form a “participial phrase”, such as noisily burping, circled by the hungry sharks, waving at the TV camera… • participles + other modifiers; • used to modify nouns and pronouns.

  33. Examples: • In his movie, Arnold Schwarzenegger uses his muscles more readily than his brain. • In his movie, Arnold Schwarzenegger uses his muscles more readily than his brain, choppingoff barbarians’ heads with his gigantic sword in another.

  34. Using participial phrases to suggest relationships Participial phrases not only wake up your sentences but also suggest time or cause-result relationship. Participial phrases suggest such relationship less directly than clauses beginning with terms like “because”, “thus”, “therefore”, and “as a result.” Example: Because many actors glared directly at the camera and did not blink for long periods of time, they started to have eye problems several years later. Glaring directly at the camera and did not blink for long periods of time, many actors started to have eye problems several years later.

  35. More examples: • Some Vietnam vets were disillusioned by the American public’s negative perception of the war. Therefore, they suffered severe mental problems when they returned to civilian life. • We pulled off the interstate. Then we descended the exit ramp to the stadium, a crowd of people came out and waved to us. Disillusioned by the American public’s negative perception of the war, some Vietnam vets suffered severe mental problems when they returned to civilian life. We pulled off the interstate, descending the exit ramp to the stadium, a crowd of people came out and waved to us.

  36. Participial phrases formed from relative clauses (by reducing subject pattern)

  37. Perfect Form Participles:Active (having discovered) & Passive (having been discovered) emphasize the “completed” action.

  38. Participial Phrases from Adverbial Clauses: Before choosing a college, a student should consider several factors. A student should consider several factors before choosing a college. Since coming to the United States three years ago, Carlos hasn’t been back home. Carlos hasn’t been back home since coming to the United States three years ago.

  39. Coming from a very conservative family, Carlos was shocked at the American system of coed dormitories. Gradually getting used to American customs, he became less homesick.

  40. After passing the TOEFL exam, he became a freshman at the college. Having passed the TOEFL exam, he became a freshman at the college. While preparing for the TOEFL exam, he lived with an American family. Preparing for the TOEFL exam, he lived with an American family. When asked about his life in the United States, he said that he was enjoying himself. Asked about his life in the United States, he said that he was enjoying himself.

  41. Position and Punctuation of Participial Phrases • A restrictive participial phrases follows the noun it modifies. There are twelve students receiving rewards this year. • A nonrestrictive phrase may precede or follow the noun it modifies. Teresa, hurrying to catch a bus, stumbled and fell. Hurrying to catch a bus, Teresa stumbled and fell.

  42. Sometimes, we can move participial phrases from one position to another in a sentence – before the main clause, after it, in the middle of it. 1. Keeping one eye on his professor, Ross quickly scanned the comic hidden behind his bulky biology textbook. 2. Ross, keeping on eye on his professor, quickly scanned the comic hidden behind his bulky biology textbook. 3. Ross quickly scanned the comic hidden behind his bulky biology textbook, keeping one eye on his professor.

  43. If the participial phrase describes something that happened before the main action of the sentence, the participial phrase will precede that main action. • Introduced twenty years ago as labor-saving devices, computerized cash registers are now installed in about 85 percent of all china stores. If the participial phrase describes something that happened after the main action of the sentence, the participial phrase will follow that main action. • John opened the brightly wrapped package, discovering a small wooden box.

  44. Using present participial phrases – two actions are occurring simultaneously, whether the phrases come before or after the main clause. • Carrying the cumbersome bass drum in front of me, I jostled my way through the stubborn crowd to the bandstand. • I jostled my way through the stubborn crowd to the bandstand, carrying the cumbersome bass drum in front of me.

  45. Practice – making participles • Peter Mark Johnson, who conducts ocean tours off the coast of Baja California, claims that animals in the wild like people. He noted that grey whales observe his tour boat from afar, then approach. They touch the craft with their snouts and refuse to leave until the startled tourists pet them. The tour guide thinks all this means that nature is not necessarily hostile. • He noted that grey whales observe his tour boat from afar, then approach, touching the craft with their snouts and refusing to leave until the startled tourists pet them.

  46. Practice: (不管是現在式或過去式,動作若是主動 -Ving. 動作若是被動,- V p.p) They, assisted by brave and dedicated abolitionists, slept in barns and churches. 1. They slept in barns and churches. They were assisted by brave and dedicated abolitionists. 2. He decided to help fugitives. He made his house into a station on the Underground Railroad. 3. Cold travelers still stay in the basement. Cold travelers are warmed by the working fireplace. 4. They have kept the basement in good condition. They have kept it as a tribute to the Underground Railroad. He, making his house into a station on the Underground Railroad, decided to help fugitives. Cold travelers, warmed by the working fireplace, still stay in the basement. They have kept the basement, as a tribute to the Underground Railroad, in good condition.

  47. Reducing Dependent Clauses • We can save words by reducing a dependent clause to a phrase or a word.

  48. Reducing Dependent Clauses to… 1. Prepositional phrases 2. Infinitive phrases 3. To participles or participial phrases 4. To adverbs. 5. To adjectives
