A complex sentence contains at least two clauses: a main clause and a subordinate clause. 2. A subordinate clause, which is dependent on the main clause for its meaning, may function in a sentence as an adjective, an adverb, or a noun. (i) An adjective clause (also called a relative clause) usually begins with a pronoun, such as who, whom, whose, that, which, where, or when, and immediately follows the noun or pronoun which it describes. (ii) An adverb clause clause begins with an adverbial conjunction, such as because, although, if, or while, and is frequently found at the beginning or the end of a sentence. (iii) A noun clause begins with the word that or a question word, such as why, what, or how, and can function in a sentence in any of the ways that a noun can. 1.To distinguish between main clause and subordinate clause. A main clause is a subject-verb combination that can function independently as a sentence. A subordinate clause is a subject-verb combination that begins with a word such as because, which, after, if and cannot function independently as a sentence. For example: Main clause (MC): the rain stopped. Subordinate clause (SC): after the rain stopped. 7 2. A subordinate clause contains a subject and a full verb; a phrase does not. For example: SC: if the doctors operate soon. Phrase (PHR): before finishing dinner. 3. Remember that a main clause, in either statement form or question form, can function alone. An adjective clause is a subordinate clause which must always follow a noun in the main clause. Some of these clauses can function in both ways (both). For example: MC: adults do well on only six hours per night. SC: that is used by navigators. Both: whom did they visit. 4. Complex sentence contain at least one main clause and one subordinate clause. Each of the following complex sentences contain at least one subordinate adjective clause which begins with a word such as: who, whom, which, that, where, when, etc. For example: Modern man struggled for many years to develop a process that he could Main clause use to separate aluminum from other element to which it was bonded. Subordinate adjective clause 1 subordinate adj clause 2 + Adj clause may be marked by introductory words such as which, whom, that, etc, or they may be unmarked. For example: The capsule [the astronauts rode in] was also designed to be used only once. (In this case, the word ” which ” is obmitted because the subject referred is object. This sentence is combined from two sentences: The astronaut road in the capsule. The capsule was also designed to be used to only once.). 5. To identify all the adverb clauses within a complex sentence. Here is the table of some of the words that can introduce subordinate adverb clauses, arranged in columns according to their meanings. Some introductory words can have more than one meaning. Time Cause/result Condition Opposition Manner Comparison After Because If even if Although As though Than 8 Since Before By the time When Whenever While Now that Until Once As soon as As\ so long as As Since So (that) Whereas In order that Unless Only if Once In case (that) Whether or not In the event (that) Provided (that) While Though Whereas even though As if as A noun clause is a subordinate clause that function as a noun. Noun clause can function as subjects, but they are more commonly used as objects of verbs of telling, feeling, and thinking. These noun clause frequently begin with the word that. For example: The doctor said that the man would get well quickly. S V O That it rained so much this year is fortunate for farmers. S V O +When a noun clause functions as an object, the word that is frequently obmitted. For example: Ambitious students feel (that) hard works is ultimately rewarded. (That can be obmitted). Noun clause can also begin with question words such as what, why, how, and so on. This type of noun clause can also function as a subject or as an object. For example: (What you said) was very nice. (Noun clause: what you said functions subject) S V Everyone knows (what you said). (Noun clause: what you said functions object) 9 S V Noun clause and infinitive phrase are often found in sentences beginning with the subject it. Both noun clause and adjective clauses following special words like fact, hope, etc, can begin with the word that but only adj clause can also begin with the word which. There is a quick way to test a clause to determine whether or not it is a noun clause: If you can insert the word is between the noun and its clause, you have a noun clause, if you cannot insert is the clause is an adj clause. Objective 4: check the verbal An infinitive is a verbal which is formed with to and the based form of the verb. Although the word to may be the first word of an infinitive, it also begins many prepositional phrases. For example: Infinitives: to eat, to walk, to enjoy Prepositional phrase: to school, to Alaska, to the dance. A gerund is a verbal which is formed by adding the suffix –ing to the base form of a verb. A gerund never function as a verb in a sentence. It always function as a noun. Gerunds should not be confused with –ing words that are part of all progressive tense verbs. For example: Gerund: swimming, singing, participating Verbs: are swimming, were singing, have been participating A verbal adjective can be formed by reducing an adjective clause to a phrase or a word. A one-word verbal adjective goes before the noun it describes. A verbal phrase follows the noun it describes. For example: Adjective clause: Doctors couldn’t save the man who was dying of cancer Verbal adj phrase: Doctors couldn’t save the man dying of cancer One-word verbal adj: Doctors couldn’t save the dying man. Like gerund and infinitive, verbal adj are formed from verbs but do not function as finite verbs. Each verb has two basic verbal adj forms: the present participle and the past participle. Verb: eat  verbal adj: eating, eaten Verb: interest  verbal adj: interesting, interested A verbal adj can take the form of either the present participle (-ing) or the participle (-d, -n, -t). when the noun that is being described is actively “doing” the 10 [...]...
