Asimov’s Three Laws of Robotics:
  1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
  2. A robot must obey any orders given to it by human beings, except where such orders would conflict with the First Law.
  3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

1950

Noun Phrase

Noun Phrases
A noun phrase (NP) can consist of one word (for example, the pronoun we or the plural noun cats), or it can consist of a noun with a number of dependents. The dependents occur before or after the noun head depending on their function. For example, the new boat that I bought yesterday is a noun phrase containing the determiner the, the adjective new, the head noun boat, and the relative clause that I bought yesterday.
Noun phrases often function as complements to the verb; for example, in the clause Many people run the marathon every year, the NPs many people and the marathon function as the subject and object respectively. The NP every year is an adjunct, which is an optional element in the grammatical structure of this clause.

a.      Noun Phrase heads

All noun phrases (NPs) have a noun or pronoun as the head. The noun is the anchor of the phrase and the phrase will not be grammatical without it. For example, the NP a really lovely dress from my favourite shop is ungrammatical if the word dress is omitted: * a really lovely from my favourite shop.
Pronouns can stand in place of an NP. An easy way to see how pronouns can substitute for larger constituents is to try substitution. We can substitute it for the NP that house on Plenty Road in the clause I have to paint that house on Plenty Road so that we have I have to paint it.

b.      Noun Phrase dependents

The Noun Phrase can also have different types of dependents, such as determiners (for example, those, the), adjectives (for example, beautiful, green), nominal modifiers (nouns which modify other nouns, for example, bluestone house), prepositional phrases (for example, in Eltham) and relative clauses (for example, which the magazine featured). The dependents modify the noun by adding information. The structure of the noun phrase the beautiful garden in Eltham which the magazine featured is given below:

A dependent in the Noun Phrase can also be categorised according to its position in the NP:
  • Determiners, nominal modifiers and adjectives occur before the Noun Phrase head. (Determiners can have modifiers as well, for example, at least twelve eggs.)
  • There is often restriction on the order of other pre-head constituents. For example, determiners always occur before adjectives: the long red satin ribbon, not *satin the red long ribbon.
  • Some adjectives (often with their own complements) can occur as post-head modifiers, for example, someone skilled, or people taller than 180cm.
  • Post-head modifiers in an Noun Phrase include prepositional phrases (for example, boats on the water), modifying NPs (for example, my sister Bertha, or children her age), relative clauses (for example, a friend [who/whom] I've known for fourteen years) and non-finite clauses (for example, swans floating on the lake).

c.      Function of Noun Phrase

Noun phrases often function as complements to the verb. This means that they fulfil specific grammatical functions required by the verb. The examples below show NPs functioning as subjects and objects in different clauses.
·         subject NPs typically appear before the verb, and control the verb's inflectional agreement (for example, Fenella sings well).
·         object NPs typically follow the verb and are affected by the situation described by the verb (for example, Atticus taught Felix).
We can see that a large NP such as in the diagram above behaves as a unit (constituent) in clause structure because we can use it as a subject or object in a sentence in a similar way to a NP with only one element, the head noun or pronoun:
(The beautiful garden in Eltham which the magazine featured]SUBJECT is closed on Mondays.

[Parliament]SUBJECT is closed on Mondays. [It]SUBJECT is closed on Mondays.
We all loved [the beautiful garden in Eltham which the magazine featured]OBJECT.
We all loved [dinner]OBJECT.
We all loved [it]OBJECT.
Other functions in the clause that an NP can fulfil include the role of complements and adjuncts.
There are a number of types of constituents that take NP complements. At clause level, an NP can function as a subject complement (for example, Georgia is an architect) or an object complement (for example, We voted Kerry class representative). NPs also funciton as complements in prepositional phrases (for example, under the bed).
Noun phrases can also function as adjuncts within a clause. Adjuncts are not essential to a clause but provide additional information (for example, We meet for lunch most Fridays).

Countable and uncountable nouns


Countable and uncountable nouns

You will learn about countable and uncountable nouns. but before you continue the lesson, look at the following chart and study the nouns.
Countable
Uncountable
books
money
friends
meat
teachers
juice
tables
milk

a.      Countable nouns (count nouns):

Countable nouns have a singular and a plural form. In plural, these nouns can be used with a number- they can be counted. (That's why they are called "countable nouns").
Example:
1 friend, 2 friends, 3 friends...
1 book, 2 books, 3 books...
Countable nouns take many.
Example:
100 friends – many friends

b.      Uncountable nouns (uncount / non-count nouns):

Uncountable nouns can only be used in singular. These nouns cannot be used with a number- they can't be counted. (That's why they are called "uncountable nouns").
Examples:
I have a lot of money. (Not 1000 money)
You say I drink a lot of milk. (Not 5 milk)
Uncountable nouns take much.
Example:
 100 money – much money
Note: Of course you can count money, milk, meat; but then you would use the currency, liter, kilo, glass,...and say that you have got:
  • 5 euros or dollars... (but not 5 money).
  • 2 liters, pints, glasses... of milk (but not 2 milk)
  • 3 kilos... of meat (but not 3 meat)
  • 10 bottles of mineral water... (but not 10 mineral water)

Indefinite articles - a and an (determiners)

A and an are the indefinite articles. They refer to something not specifically known to the person you are communicating with.
A and an are used before nouns that introduce something or someone you have not mentioned before:-
For example:
"I saw an elephant this morning."
"I ate a banana for lunch."

A and an are also used when talking about your profession:-
For example:
"I am an English teacher."
"I am a builder."


Note!

You use a when the noun you are referring to begins with a consonant (b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, v, w, x, y or z), for example, "a city", "a factory", and "a hotel".
You use an when the noun you are referring to begins with a vowel (a, e, i, o, u)
Pronunciation changes this rule. It's the sound that matters, not the spelling.

Definite Article - the (determiners)

There are two ways to pronounce "the". One "thuh" and the other "thee". To learn when we use them see the pronunciation files: How to pronounce "the".
You use the when you know that the listener knows or can work out what particular person/thing you are talking about.
For example:
"The apple you ate was rotten."
"Did you lock the car?"

You should also use the when you have already mentioned the thing you are talking about.
For example:
"She's got two children; a girl and a boy. The girl's eight and the boy's fourteen."

We use the to talk about geographical points on the globe.
For example:
the North Pole, the equator

We use the to talk about rivers, oceans and seas
For example:
the Nile, the Pacific, the English channel

We also use the before certain nouns when we know there is only one of a particular thing.
For example:
the rain, the sun, the wind, the world, the earth, the White House etc..

However if you want to describe a particular instance of these you should use a/an.
For example:
"I could hear the wind." / "There's a cold wind blowing."
"What are your plans for the future?" / "She has a promising future ahead of her."

The is also used to say that a particular person or thing being mentioned is the best, most famous, etc. In this use, 'the' is usually given strong pronunciation:
For example:
"Harry's Bar is the place to go."
"You don't mean you met the Tony Blair, do you?"

The passive voice

The passive voice


The passive voice is a grammatical construction (specifically, a "voice"). The noun or noun phrase that would be the object of an active sentence (such as Our troops defeated the enemy) appears as the subject of a sentence with passive voice (e.g. The enemy was defeated by our troops).
The subject of a sentence or clause featuring the passive voice denotes the recipient of the action (the patient) rather than the performer (the agent). The passive voice in English is formed periphrastically: the usual form uses the auxiliary verb be (or get) together with the past participle of the main verb.
For example, Caesar was stabbed by Brutus uses the passive voice. The subject denotes the person (Caesar) affected by the action of the verb. The agent is expressed here with the phrase by Brutus, but this can be omitted. The equivalent sentence in active voice is Brutus stabbed Caesar, in which the subject denotes the doer, or agent, Brutus. A sentence featuring the passive voice is sometimes called a passive sentence, and a verb phrase in passive voice is sometimes called a passive verb.
English allows a number of passive constructions which are not possible in many of the other languages with similar passive formation. These include promotion of an indirect object to subject (as in Tom was given a bag) and promotion of the complement of a preposition (as in Sue was operated on, leaving a stranded preposition).
Use of the English passive varies with writing style and field. Some publications' style sheets discourage use of the passive voice, while others encourage it. Although some purveyors of usage advice, including George Orwell (see Politics and the English Language, 1946) and William Strunk, Jr. and E. B. White (see The Elements of Style, 1919), discourage the English passive, its usefulness is generally recognized, particularly in cases where the patient is more important than the agent, but also in some cases where it is desired to emphasize the agent.

Identifying the English passive

The passive voice is a specific grammatical construction; not every expression that serves to take focus away from the performer of an action is classified as an instance of passive voice. The essential components of the English passive voice are a form of the auxiliary verb be (or sometimes get), and the past participle of the main verb denoting the action. For example:

... that all men are created equal..
We have been cruelly deceived.
The captain was struck by a missile.
I got kicked in the face during the fight.

(For exceptions, see Additional passive constructions below.) The agent (the doer of the action) may be specified, using a prepositional phrase with the preposition by, as in the third example, but it is equally possible to omit this, as is done in the other examples.
A distinction is made between the above type of clause, and those of similar form in which the past participle is used as an ordinary adjective, and the verb be or similar is simply a copula linking the subject of the sentence to that adjective. For example:

I am excited (right now).

This would not normally be classed as a passive sentence, since the participle excited is used adjectivally to denote a state, not to denote an action of excitation (as it would in the passive the electron was excited with a laser pulse). See Stative and adjectival uses below.
Sentences which do not follow the pattern described above are not considered to be in the passive voice, even if they have a similar function of avoiding or marginalizing reference to the agent. An example is the sentence A stabbing occurred, where mention of the stabber is avoided, but the sentence is nonetheless cast in the active voice, with the verbal noun stabbing forming the subject of the simple past tense of the verb occur. (Similarly There was a stabbing.) Occasionally, however, writers misapply the term "passive voice" to sentences of this type.[8] An example of this loose usage can be found in the following extract from an article from The New Yorker about Bernard Madoff (bolding and italics added; bold text indicates the verbs misidentified as passive voice):
Two sentences later, Madoff said, "When I began the Ponzi scheme, I believed it would end shortly, and I would be able to extricate myself, and my clients, from the scheme." As he read this, he betrayed no sense of how absurd it was to use the passive voice in regard to his scheme, as if it were a spell of bad weather that had descended on him . . . In most of the rest of the statement, one not only heard the aggrieved passive voice, but felt the hand of a lawyer: "To the best of my recollection, my fraud began in the early nineteen-nineties.
The intransitive verbs would end and began are in fact in the active voice. Although the speaker uses the words in a manner that subtly diverts responsibility from him, this is not accomplished by use of passive voice.
Examples of misuse of the term are also found in Strunk and White's influential The Elements of Style. Professor Geoffrey Pullum notes that three out of four "passive voice" examples given in that book do not in fact contain passives: "There were a great number of dead leaves lying on the ground" (no sign of any passive); "It was not long before she was very sorry that she had said what she had" (again, no sign of the passive); "The reason that he left college was that his health became impaired" (here became impaired is an example of the adjectival, not passive, use of the past participle)

Form of Passive
Subject + finite form of to be + Past Participle (3rd column of irregular verbs)
Example: A letter was written.
When rewriting active sentences in passive voice, note the following:
the object of the active sentence becomes the subject of the passive sentence
the finite form of the verb is changed (to be + past participle)
the subject of the active sentence becomes the object of the passive sentence (or is dropped)

Passive Sentences with Two Objects Level: intermediate

Rewriting an active sentence with two objects in passive voice means that one of the two objects becomes the subject, the other one remains an object. Which object to transform into a subject depends on what you want to put the focus on.

Subject
Verb
Object 1
Object 2
Active:
Rita
wrote
a letter
to me.
Passive:
A letter
was written
to me
by Rita.
Passive:
I
was written
a letter
by Rita.
.
As you can see in the examples, adding by Rita does not sound very elegant. That’s why it is usually dropped.

Personal and Impersonal Passive
Personal Passive simply means that the object of the active sentence becomes the subject of the passive sentence. So every verb that needs an object (transitive verb) can form a personal passive.
Example: They build houses. – Houses are built.
Verbs without an object (intransitive verb) normally cannot form a personal passive sentence (as there is no object that can become the subject of the passive sentence). If you want to use an intransitive verb in passive voice, you need an impersonal construction – therefore this passive is called Impersonal Passive.
Example: he says – it is said
Impersonal Passive is not as common in English as in some other languages (e.g. German, Latin). In English, Impersonal Passive is only possible with verbs of perception (e. g. say, think, know).
Example: They say that women live longer than men. – It is said that women live longer than men.
Although Impersonal Passive is possible here, Personal Passive is more common.
Example: They say that women live longer than men. – Women are said to live longer than men.
The subject of the subordinate clause (women) goes to the beginning of the sentence; the verb of perception is put into passive voice. The rest of the sentence is added using an infinitive construction with 'to' (certain auxiliary verbs and that are dropped).
Sometimes the term Personal Passive is used in English lessons if the indirect object of an active sentence is to become the subject of the passive sentence.
