English for Starters, Vocational Stream – Industrial
English for Starters, Vocational Stream – Industrial, is an English
language course that was specially written for vocational / industrial
secondary schools in Syria The course progresses from an intermediate level
of English in Grade 10 to an advanced level of English in Grade 12 The book
introduces students to concepts in industry; it assumes no prior knowledge
of industrial skills on the part of students and teachers
The course aims to review and consolidate the language and skills learnt
at previous levels and equip students for their future foreign language
needs in the following areas: language skills (reading, listening, speaking and
writing), grammar, vocabulary and industrial knowledge It enables students
to perform routine tasks at work and to take part in social interaction in an

Read the text then answer the following questions
Electricity must be transmitted from the power plant to the places that use it such as fl ats and offices
The electric current needs to be sent over long distances, so set up transformers are used to increase the voltage of the current which is generated by the plant F or example, if a power plant generates 6 6 kilovolts of electricity, the voltage is increased to 110 kilovolts before it is transmitted
O verhead transmission lines are used to carry the electricity from the power plant to the substations These lines are suspended from steel towers called pylons
W hen it is not possible to use overhead transmission lines, underground lines are used They are used, for example, in big cities or under the sea
A t the substation, the voltage of the current is decreased to 6 6 kilovolts, and other low voltages, by a step down transformer The voltage may be decreased again by another step down transformer near the place where the electricity will be used
D istribution lines carry the electricity from the substations to buildings, factories, schools and many other users

a decrease the voltage b produce electricity c increase the voltage
5 are used to distribute electricity to the places that use it

Definitions Function of Device Function of Parts Operation of Device Main Parts of Device Title
Fibre-Optic Cable
A fibre¯optic cable is a cable which carries hundreds or thousands of fibre¯optic
wires A fibre¯optic wire is a long, thin thread of very pure glass, about the diameter
of a human hair
Fibre¯optic cables are used for carrying digital signals in the form of light waves
over long distances
A fibre¯optic wire consists of the following parts: a core, a cladding and a buffer
coating The core is located in the centre and is made of thin glass The cladding
is made of optical material and surrounds the core The buffer coating is made of
plastic and surrounds the cladding and core
The function of the core is to carry the light signals The purpose of the cladding is to
reflect the light back into the core, and to prevent it from escaping from the core The
buffer coating has the function of protecting the fibre from damage and moisture
The light in an optical fibre travels through the core by constantly bouncing from
the cladding, which acts as a mirror Because the cladding does not absorb any
light from the core, the light wave can travel great distances

Free Electricity!
Intel said it is researching technology to harvest free energy from the environment, which could lead to devices such as mobile phones running for indefinite periods without recharging Intel is working on tiny sensors that can capture energy from sources such as sunlight and body heat to power personal electronic devices such as MP3 players, cell phones, portable handheld gaming devices, etc
Intel is also looking at powering a mobile phone by converting the energy the user is creating simply by moving the phone›s trackball Additionally, the radiation of cell phone or TV signals might be used to power devices One example given is an accelerometer buried in the wall of a building that could automatically recharge itself by harvesting the energy of radiation from a cell phone tower

Read the text then answer the following questions
A Scientific research satellites gather data for scientific analysis These satellites are usually designed
to perform one of three kinds of missions (1) Some gather information about the composition and effects of the space near the Earth (2) O ther satellites record changes in the Earth and its atmosphere (3) Still others observe planets, stars and other distant obj ects
B Earth observing satellites are used to map and monitor our planet’s resources U nder constant
and consistent illumination from the Sun, they take pictures that computers on Earth combine and analyse Scientists use Earth observing satellites to locate mineral deposits to determine the loca-tion and size of freshwater supplies, to identify some of the sources of pollution and study their effects and to detect the spread of disease in crops and forests
C Com munication satellites receive radio signals from one location and transmit them to another
Coun tries and commercial organisations, such as television broadcasters and telephone companies, use these satellites continuously
D Ar tificial satellites are classified according to their mission There are six main types of artificial
satellites: scientific research, weather, communication, navigation, Earth observing and military
E N avigation satellites enable operators of aircraft, ships and land vehicles anywhere on Earth
to determine their locations with great accuracy N avigation satellites operate in networks, and signals from a network can reach receivers anywhere on Earth
F Military satellites include weather, communications, navigation and Earth observing satellites
used for military purposes Some military satellites – often called “s py satellites” – can detect the
launch of missiles and the course of ships at sea
G W eather satellites help scientists study weather patterns and forecast the weather W eather
satellites observe the atmospheric conditions over large areas Some weather satellites measure temperature, air pressure and precipitation They are eq uipped to detect distress signals from all commercial and many private planes and ships
