Part 3 : Simple, Complex, and
Compound Sentences
Simple Sentence
Compound Sentence
Complex Sentence
The sentence contains a subject and a verb and expresses a complete thought.
Example:
Rahman (subject) plays (verb) football every afternoon.
In this type of sentence, there is only one independent clause and there might be multiple dependent clauses joined by non-finite verbs (gerund, participle, infinitive. See Unit 3). But there can be only one finite verb.
Example:
While going (non-finite verb: present participle) there, I (subject) met (finite verb) him.
Despite being (non-finite verb: present participle) sick, he attended (finite verb) the meeting.
There is no use of conjunction (to join clauses) in simple sentences. But joining words can be used by ‘and’.
Bread and butter are my breakfast.
Rahman and Selim are two friends.
ii) Compound Sentence
In this type of sentence, there are multiple independent clauses and no dependent clause. All the clauses are joined together by coordinating conjunctions. Such sentences have two finite verbs and two subjects.
List of Coordinating Conjunctions
Coordinating conjunctions connect two equal parts of a sentence. Here are they:
And, but, nor, or, so, yet
Examples:
I (subject) tried (finite verb) to speak Spanish, and my friend (subject) tried (finite verb) to speak English.
Rahman (subject) played (finite verb) football, so Ria (subject) went (finite verb) for shopping.
This type of sentence consists of at least one independent clause and one dependent clause. There are two finite verbs joined by subordinating conjunction.
Subordinate conjunctions connect two unequal parts, e.g., dependent and independent clauses.
Here is the list of subordinating conjunctions:
Since, as, when, though, although, so that, whenever, because, than, whereas, that, wherever, that, whether, if, though, which, till, while, unless, who, until, why, how, what
Examples:
When (subordinator) he (subject) handed (finite verb) in his homework, he (subject) forgot (finite verb) to give the teacher the last page.
The teacher (subject) returned (finite verb) the homework after (subordinator) she (subject) noticed (finite verb) the error.
The students (subject) are studying (finite verb) because (subordinator) they (subject) have (finite verb) a test tomorrow.
Roy (subject) and Rahman (subject) went (finite verb) to the movies after (subordinator) they (subject) finished (verb) studying.
Complex sentences with relative pronouns as subordinators/subordinating conjunctions:
The woman (subject), who (subordinate) my mom (subject) talked to, sells (verb) cosmetics.
The book (subject) that (subordinate) Ria (subject) read is (verb) on the shelf.
The town (subject) where (subordinate) I (subject) grew up is (verb) in Bangladesh.

Part 5 : Active and Passive Sentences
Active Sentence means the subject of the sentence is the doer of the action.
Example:
He (subject: doer) plays football.
Passive Sentence means the subject of the sentence is not the doer of the action. In three situations, passive is mandatory:
When the subject is unknown
When the subject is unnecessary to mention
When the speaker wants to hide the subject
Note: Learn more in Unit 4 about Active and Passive Voice
Example:
He (subject: non-doer) was arrested last night.
Note: Here the doer is the police which is hidden in the meaning and it is unnecessary to mention this subject.
Active : I must do it.
While transforming, the object (non-doer) in the active becomes the subject (non-doer) in the passive. And the subject in the active becomes the object. Usually preposition ‘by’ is used in the passive to add the subject in the active.
Passive: Geetanjali was written by Tagore.
Here Tagore is the subject and the doer. So the sentence is Active. As it is in Past Simple Tense, the structure is: Subject + v2 (past form of verb) + object.
When the doer is unknown, ‘by + object’ is not used:
Example:
Passive: My watch was stolen.
Here the doer (who did the action) is unknown, so there is object in the sentence.
In some cases, when the object in active is material or substance, ‘by’ preposition is not used, rather than ‘with’ is used:
Example:
Active: Gas filled the kitchen.
Passive: The kitchen is filled with gas.
Sometimes, there are two objects (non-doers) in active sentences.
For example:
Active: He teaches us English.
‘English’ and ‘us’ both are objects and non-doers. It can be made passive in two ways. Both are correct:
Passive: English is taught to us by him.
Passive: We are taught English by him.
Unchanged extension/compliment of verb:
Active: They kept me waiting.
Passive: I was kept waiting.
Here the word waiting is the compliment of the verb and it is not changed in passive.
Some sentences are always passive:
For example: Get + past participle:
I got dressed as quickly as possible.
Someone got hurt in the accident.
Other prepositions except ‘by’:
Active: Your conduct surprises me.
Passive: I am surprised at your conduct.
Active: This news alarmed us
Passive: We are alarmed at this news.
With infinitive:
Active: make/see/hear/help/watch + v1
Passive: make/see/hear/help/watch + to + v1
Example:
Active: He made me laugh.
Passive: I was made to laugh.
Active: He saw a mango fall.
Passive: A mango was seen to fall.
In case of infinitive:
Active: To + v1
Passive: To + be + v3
Example:
Active: I want to do it.
Passive: It is wanted to be done by me.
Note: Here both verbs (finite and non-finite) are changing.
In case of Modal:
Active: Modal + v1
Passive: Modal + be + v3
Example:
Active: I can do it.
Passive: It can be done by me.
a. Do/did/does in active sentences becomes is/are/was/were in passive sentences.
Example:
Active: Do you want it?
Passive: Is it wanted by you?
b. question statements with auxiliary verbs in active sentences:
Active: Can they solve this?
Passive: Can this be solved by them?
c. In ‘Wh’ question word sentences:
Active: What do you want?
Passive: What is wanted by you?
Imperative Sentence
In case of order/command:
A passive imperative begins with ‘let’, followed by the object in the active.
Example:
Passive: Let + subject + be + v3 (past participle)
Active: Let her to wait here.
Passive: Let her be told to wait here.
Active: Close all the gates.
Passive: Let all the gates be closed.
In case of advice/suggestion:
Passive: should/must + be + past participle
Active: Take medicine on time.
Passive: Medicine should be taken on time.
Imperative request:
Active: Please give me some more time.
Passive: You are requested to give me some more time.
Multiple Clauses
Example:
Active: It is time to change our home.
Passive: It is time our home to be changed.
Active: There is no time to lose.
Passive: There is no time to be lost.
In other cases, the whole object becomes the subject:
Active: Everyone says that he is a fool.
Passive: That he is a fool is said by everyone.
In case of universal/general statements, ‘it is believed’, or ‘it is hoped’, ‘it is said’ is used in passive. The rest of the clause remains unchanged.
Active: People believe that he is skilled.
Passive: It is believed that he is skilled.
Compound Sentences
Active: They draft applications and type them.
Passive: Applications are drafted and typed.
Taking a new verb:
Active: He reads two hours.
Passive: Two hours are taken in reading by him.

Active: The sun rises in the East.
Passive: It is said the sun rises in the East.
When adjective is object in active:
Active: Honey tastes sweet.
Passive: Honey is sweet when it is tasted.

Active: The cows are milking.
Passive: The cows are being milked.
