ENGLISH WORKSHEET-2 1. Read the passage below and attempt the questions that follow: 1. Bubble wrap is a flexible transparent plastic material used for packing fragile items. It was invented by
two engineers Al Fielding and Swiss inventor Marc Chavannes in Hawthorne, N.J. in 1957. However both
of them were not trying to make a product to be used as packaging material. In fact they were trying to
create textured wallpaper. They started out by sealing two shower curtains together in such a way that
it would capture air bubbles which would make the textured appearance for their wallpaper. But this
wallpaper idea didn’t sell too well. 2. Not to be deterred, they then set about finding another use for their product. The alternate use they
came up with was to use it as greenhouse insulation. While bubble wrap by itself does create somewhat
of an insulating effect, this idea didn’t become popular either. 3. It was three years after the initial creation of Bubble Wrap that Frederick W. Bowers, a marketer at
Sealed Air, which makes Bubble Wrap, finally came up with the perfect use for their product. On
October the 5, 1959, IBM announced their new 1401 variable word length computer. Bowers got the
idea that Bubble Wrap could be used as a good packaging material to protect the computer while it was
being shipped. He then pitched the idea to IBM and demonstrated Bubble Wrap’s protective abilities.
His demonstration went over well and IBM began purchasing Bubble Wrap to protect their 1401 and
other fragile products they sold and shipped. 4. One of the downsides to Bubble Wrap has always been the space it takes up during shipping and
storage, for customers who are just buying the Bubble Wrap. In order to get around this problem, one
of the dreams of the original inventors was that they’d someday be able to create a Bubble Wrap that
customers could self-inflate, as needed. 5. While originally being used primarily for packaging for electronics equipment, today the vast majority
of Bubble Wrap made is used for food packaging. Because bubble wrap makes a satisfying popping
sound when compressed and ruptured, it is often used as a source of amusement. 1.1. Fill in the blanks:
(a) Bubble wrap was, at first, thought by the two engineers to be useful to___.
(b) The engineers were trying to create textured wallpaper by ____________.
(c) The alternate use of their product was___________________________.
(d) IBM purchased Bubble Wrap to __________________.
(e) The flipside of bubble wrap is ___________________________________.
(f) The solution thought of was ____________________________________.
(g) The word which means the same as „surfaced is _______ (para 1).
(h) The word which means the same as „exhibition is _______ (para 3).
(i) The word which means the same as „cracking is _________ (para 5).
(j) The word which means the same as „crushed is __________ (para 5) 2. Drinking water is becoming a rare commodity. Industrial development is filling our rivers, seas and
oceans with toxic pollutants which are a major threat to human health. You as a student is deeply
saddened to see water pollution as an appalling problem, which is powerful enough to lead the world
on a path of destruction. Write a letter to the people of Delhi, to make them aware about the causes of
water pollution and also suggest measures to prevent water pollution. (About 100 -120 words) You may use the clues given below:
• industrial waste
• treatment of wastes before discharge

3. Nowhere in the world is found such beauty, different and diversified climate, flora, fauna, religions,
languages, dialects, dressing patterns, life style and rituals, like India. The Indian tourism and hospitality
industry has emerged as one of the key drivers of growth among the services sector in India. Write a
letter to the Ministry of Tourism in about 100-120 words, offering suggestions for promoting the
tourism industry. You may use the clues given below:
• indirectly generates more employment and helps to raise our economy as foreign money will flow in
• development of infrastructure to meet the present and future needs of tourists
• starting overseas offices at different countries to promote India as a tourism destination
• try to provide best of the services in Air India and in Indian Rail
