RATIONALE
With the increasing variety of options and opportunities emerging for Diploma
students, fulfilling their communication needs become highly important. Proficiency in
communication can equip them to be confident and to cope with the employment and
educational situation in any part of the world. Communication levels inspire higher
aspiratory levels in the process of upward mobility in career and socio-cultural evolution
of the young individuals. At the end of the course the student should be able to express
himself in oral and written communication effectively.
SPECIFIC INSTRUCTIONAL OBJECTIVES
All the four skills - listening, speaking, reading and writing - should be developed
in the communication process for a polytechnic student who is at the intermediate level
and transitional period from school to college.
Silent reading of the English text book acquaints him with the grammatical
structures and the nuances of the language indirectly and also triggers reaction in the
thinking process according to the student’s specific learning background. Loud
reading equips the student with confidence and practice for oral communication. Both
these should be given due importance in the class room situation.
Developing listening skills equip them with the necessary focus in understanding
oral communication without difficulty to react and interact properly. Proper exposure in
developing these two skills facilitates speaking and writing which are very essential in day
to day interaction in any official, social or personal context. Matching to the entry level
quality of the polytechnic student and his technical background, this text book is aimed at
fulfilling the needs of all the four communication skills with suitable texts, language
exercises and activities. Grammar items prescribed in the syllabus are embedded in the prescribed texts to
make the teaching learning process contextualised and activity based to ensure proper
textual orientation. Exercises and group activities are given in the text itself for the
students to get practiced.

stage.
Mr. Nair was addressing the inaugural session of the 8th International Conference on
‘Low Cost Planetary Missions’ here. He said ISRO was poised to launch the Chandrayaan-2
mission to land on the Moon and conduct experiments in 2012-13. This would be followed by a
manned expedition to the Moon in 2015 and plans to explore Mars, later.
The five-day conference, organized by ISRO in collaboration with the International
Academy of Astronautics (IAA) and the Astronautically Society of India (ASI), was
inaugurated by Chief Minister Mr. Digambar Kamat. The Goa Minister for Science and
Technology Mr. Churchill Alemao was also present.
Speaking about low-cost planetary missions, Mr. Nair said India had set a trend in
building low-cost satellites with Chandrayaan-1 being the best example. It was below $100
million as compared to the nearly $500 million that were spent on similar expeditions by other
developed countries.

The solar system
Our solar system consists of the sun, the nine planets and the asteroids, comets
and meteoroids that are associated with the planets. The nine planets that make up our
solar system are Mercury, Venus, Earth, Mars, Jupiter, Uranus, Neptune and Pluto.
Mercury is closest to the sun. It is hot and dry. Venus is one of the brightest objects in the
sky after the sun and the moon. Venus is also the hottest planet in the solar system. Next
is the Earth, the only living planet. After Earth is Mars which is also called the Red
Planet. Mars is very dry now.
Jupiter is the largest planet. Its bright colour comes from its clouds. Saturn is
the second largest planet and has wide rings. The planet Uranus is a bright blue colour.
After Uranus is Neptune. Neptune rotates around the sun once in every 164 years. Pluto
is the farthest planet from the sun.
