C- Reading Comprehension

5- Read the following passage, then answer the questions below:

Plastics are very important in industry. Some plastics are made
from natural substances like rubber or wood. These are chemically treated to
produce natural plastics. But most plastic are synthetic. They are made from
petroleum products like polyester and polythene.

Plastics are very useful in industry. They are often used as
cheap substitutes for natural substances. This is because the properties of
plastics can be controlled to suit different purposes. In this way, plastics
can be used to manufacture many products, from cooking pots and coverings for
electric cables to textiles and car bodies.

A) Answer the following questions:

1. What are most plastics
made from?

2. What are plastics used
for?

3. Why are we able to
control the properties of plastics?

B) Choose the correct answer from a, b, c or d:

4. Some natural plastics
are made from

a) petroleum products b)
synthetic products
c) rubber or wood d)
chemical substances

5.types of plastics are mentioned in the passage.

substitutes for natural substances.

a) All b)
Some c) Few d) Many

7. Polyester and
polythene are plastics.

a) natural b)
synthetic c) ordinary d) normal

ملخص على الدرس

What makes an aero plane rise into the air?ما الذى يجعل الطائرة ترتفع فى الهواء

• The most important
factor is the shape of the wing.

• Air approaches the wing
at high speed and splits into two air currents.

• One air current goes
over the upper surface of the wing, and the other one

goes under the lower
surface of the wing.

• The upper air current
moves faster than the lower air current because of the

shape of the wing.
This decreases the air pressure on the top of the wing.

• The lower air current
moves more slowly than the upper current This

increases the air
pressure on the bottom of the wing.

• The higher pressure
from below pushes the wing upwards to the lower

pressure area.

• The plane can rise more
by increasing its speed or by changing the angle of

the wing. This can be
done by lowering the flaps or ailerons.

Complete these sentences. Choose the correct word in brackets:

(a) Air
travels faster over the top surface of the wing.

(b) Air
travels slower under the bottom surface of the wing.

(c) The
air pressure is lower on the top of the wing.

(d) The
air pressure is higher on the bottom of the wing.

(e) Lower
pressure pulls the wing upwards.

Answer the following questions:

(a) What
do these words refer to? one (line 5); this (line 15).

One (line 5) = the air current

this (line 15) = changing the angle of the wing

(b) What
makes the upper air current travel more quickly than the lower (current)?

The shape of the wing.

(c) What
causes the wing to rise into the air?

ft is pushed up by the higher air current from below.

(d) What
is the function of an aileron or flap on a wing?

Changing the angle of the wing.

At one-week
intervals, or every 1,000 kin, whichever is the sooner.
