me, etc.

Exercise 22. Make up general and disjunctive questions and answer them ac-
cording to the models to enhance your speaking skills. Pay your attention to 
the forms of the verb “to be”.
Model A:
This internal combustion engine is very efficient.

Is this internal combustion engine very efficient? — Yes, it is.
 
This internal combustion engine is very efficient, isn’t it? — Yes, it is. 
1. An internal combustion engine is an engine in which combustion of the 
fuel takes place in a confined space, producing expanding gases used directly to 
provide mechanical power. 2. The most significant distinction between mod-
ern internal combustion engines and the early designs is the use of compres-
sion. 3. The Wankel engine is the only design that has ever become common 
in an automobile. 4. The combustion chamber is in the closed end of each 
cylinder in reciprocating engine. 3. The rotary engine is made of a block (sta-
tor) built around a large non-concentric rotor and crankshaft.
Model B:
Different kinds of fuel are used in engines.
 
Are different kinds of fuel used in engines? — Yes, they are.
 
Different kinds of fuel are used in engines, aren’t they? — Yes, they are.
1. Combined fuels are used in developing third world countries because of 
the high cost of the diesel fuel. 2. In radial engines, the pistons are positioned 
in a circular plane around a circular crankshaft. 3. In V-type engine, two banks 
of cylinders are placed at an angle with each other along a single crankshaft. 
4. The combustion chambers are built into the non-rotating block. 5.
 
The con-
necting rods of the pistons are connected to a master rod.
