Lesson 2

The lesson plan

  1. Lead-in (5 min)

  2. Lexical exercises (20 min)

  3. Speaking practice (60 min)

  4. Homework (3 min)

LEAD-IN

The 20th century can be considered the Computer Age. The remarkable thing about the Computer Age is that so much has happened in such a short time.

Ask students to tell about the history of computer science: main periods?

The periods of computer science development:

circa 2400 BCE; before the 1920s; after the 1920s; after the late 1940s; in 1948

LEXICAL EXERCISES

I. Ask students to give definitions to words and word combinations which they have learnt at the previous lesson and to spell them:

circa– (used with a date) at the approximate time of

computer science– the study of computers and their application

gradually – slowly, over a long period of time

logical– performed by, used in, or relating to the logic circuits in a computer

to run– to launch, to perform a program

BCE– abbreviation for Before Common Era

computation– a calculation involving numbers or quantities

analog– using a continuously changing range of physical quantities to measure or store data

Turing machine– a hypothetical universal computing machine able to modify its original instructions by reading, erasing, or writing a new symbol on a moving tape of fixed length that acts as its program

to refer to– to be relevant (to)

purely– only, completely

digital– using a system of receiving and sending information as a series of the numbers one and zero, showing that an electronic signal is there or is not there

Turing test– a proposed test of a computer’s ability to think, requiring that the covert substitution of the computer for one of the participants in a keyboard and screen dialogue should be undetectable by the remaining human participant

abacus (pl abaci) – a counting device that consists of a frame holding rods on which a specific number of beads are free to move. Each rod designates a given denomination, such as units, tens, hundreds, etc., in the decimal system, and each bead represents a digit or a specific number of digits

to store– to enter or retain (information) in a storage device

to evolve– to develop or cause to develop gradually

value– a particular magnitude, number, or amount

to employ– to give somebody a job to do for payment

to invent– to create or devise (new ideas, machines, etc.)

onset– a start; beginning

to perform– to do, to carry out something

II. Learning new vocabulary for the theme “COMPUTER”. Ask students to match computer terms written in bold with definitions given below. Then ask them to read matched pairs aloud and put between the term and its definition the verb “is”. For example,

Computer science is the study of computers and their application.

Mode, drive, access, driver, multitasking, bus, ROM, device, motherboard, program.

  1. Motherboard is the main board in a computer, into which the circuits are plugged.

  2. Device is a combination of physical components forming a unit that performs a specific function, such as storage or I/O.

  3. ROM is a type of memory chip that can be read but cannot be written on or altered.

  4. Drive is a unit that reads and writes data on an external storage device.

  5. Driver is a program that controls devices or other programs.

  6. Access is the ability to store or retrieve data.

  7. Bus is a circuit for the transfer of data or electrical signal between two devices.

  8. Mode is a method or condition of operation.

  9. Multitasking is the technique of concurrently executing a number of related tasks in the same partition.

  10. Program is a logically arranged set programming statements defining the operation to be performed by a computer.

III. Ask students to read the words as they are used in the following sentences and to try to come up with students’ own definition.

  1. Using computers to create graphics and sounds, virtual reality makes the viewer believe he or she is in another world.

  2. Three-dimensional images are created using technology that fools the viewers’ mind into perceptive depth.

  3. Plug a terminal directly into the brain via a prepared skull and you can enter cyberspace.

  4. I’ve got a set of eyephones, 3D goggles, a fiber optic glove and the rest of the gear.

  5. There are many word substitutes for invalids, e.g. the handicapped, challenged by birth or by accidents, disabled people.

  6. The bowman took a deep breath, aimed at the target and shot, but the arrow went astray.

Virtual reality – a computer-generated environment that, to the person experiencing it, closely resembles reality.

Three-dimensional (3D) – having, or relating to three dimensions; simulating the effect of depth by presenting slightly different views of a scene to each eye.

Cyberspace – all of the data stored in a large computer or network represented as a three-dimensional model through which a virtual-reality user can move.

Gear – equipment for a particular operation.

Disabled – lacking one or more physical powers, such as the ability to walk or to coordinate one’s movements, as from the effects of a disease or accident, or through mental impairment

To go astray – to be mislaid; go missing.

Grammar explanation

Explain students the formation of the Present Perfect Tense. You may use it as a self-study activity. Additional information students can find in “Essential Grammar In Use. Raymond Murphy”.

Ask students to listen to the Present Perfect explanation from BBC Learning English (06:00 min).

BBC Learning English

Grammar Challenge

http://www.bbclearningenglish.com/

Nuala’s Grammar Explanation:

Present perfect

Nuala: Elena used the present perfect ‘I’ve lived’. We use the present perfect when we want to talk about a period of time that started in the past and continues until now. If the activity is completed or finished or we mention the exact time something happened, we use the past simple. Listen to Finn:

Finn: I lived in London for 20 years.

Stop the audio file and ask students to write down Finn’s words and to pronounce them.

Continue playing the audio file.

We use the present perfect to talk about an action that began in the past and is still continuing now, sometimes called the unfinished past.

Finn: I haven’t experienced many cities in my life.

Stop the audio file and ask students to write down Finn’s words and to pronounce them.

Continue playing the audio file.

He hasn’t experienced many cities in his life. The period of time we are talking about is his life, which hasn’t finished yet.

Elena: I’ve lived here for 6 years.

Stop the audio file and ask students to write down Elena’s words and to pronounce them.

Continue playing the audio file.

She’s lived here for six years means she came to London six years ago and she’s still here now.

So, to recap then: We use the present perfect to talk about an action or state that began in the past and is still continuing now. That’s all from me, good luck with your grammar challenge!

Host: OK. That’s the Present Perfect. Are you ready for your grammar challenge?

Fatima: Yes, I am ready.

H: OK. We are going to talk a little bit about the actor Tom Cruise. With the prompts that I give you have to make a true sentence about Tom. OK. Here is the first one.

He …………. acting in films in 1981. Begin.

Stop the audio file and ask students to write down the answer they think is correct.

Continue playing the audio file.

F: He began acting in films in 1991.

H: Oh, in 1981.

F: Oh, in 1981.

H: OK. Well done. OK. That was the Simple Past. Good.

He …………. more than 30 movies. Start.

Stop the audio file and ask students to write down the answer they think is correct.

Continue playing the audio file.

F: He starts-ts-ts. I don’t know.

H: Do you think it’s Present Perfect or Past Simple?

F: Past Simple, I think.

H: Is he making movies now?

F: Yes. Still.

H: So, he’s still making movies. So, he can start in some more movies.

F: He has started more than 30 movies.

H: OK. Well done.

He ……………. three Golden Globe Awards. Win.

Stop the audio file and ask students to write down the answer they think is correct.

Continue playing the audio file.

F: He has won three Golden Globe Awards.

H: Excellent.

He ……………. in the first Mission Impossible film in 1996. And use the verb “act”.

Stop the audio file and ask students to write down the answer they think is correct.

Continue playing the audio file.

F: He acted in the first Mission Impossible film in 1996.

H: You got. Exactly. There is the Simple Past because we have 1996. It’s in the past, it’s finished. It’s Simple Past.

He …………….. three times. Be married.

Stop the audio file and ask students to write down the answer they think is correct.

Continue playing the audio file.

F: He married three times.

H: If he was dead you could say that. But he is still alive. So, maybe he ….

F: He has been married three times. H: Excellent. Very good. Well done.

Check students’ answers.

Then ask students to listen to the Present Perfect explanation from BBC Learning English once more. Ask students to tell what the audio file is about.
