Read the following and then answer the questions :
You have got some things that are complicated and you don’t know
much about them. Your tongue is about 10 centimeters long . It is covered with
taste buds . These are tiny nerve endings, which enable you to taste your food.
Babies are born with taste buds all over their mouths . Theses gradually
disappear as they grow older leaving only those on the tongue. An adult has
about 1.000 taste buds.
We can taste our food when
saliva, a liquid produced by the mouth, dissolves chemicals in the food and
washes them over taste buds. There are four basic tastes : Sweet, sour, salt
and bitter. All the taste buds can detect all these tastes to some extent, but
different areas of the tongue detect different tastes best .
Sweet tastes such as
sugar, are best detected by the taste buds at the tip of the tongue. Salt is
detected by those at the front sides of the tongue. The taste buds along the
edges at back of the tongue are good at detecting sour tastes , such as lemon,
and those on the back of the tongue detect bitter tastes such as coffee . There
are no taste buds in the center of the tongue.
The tongue is also used
in speaking . The combined action of the tongue, throat, mouth and lips changes
the sounds into words .
A) Answer the following
questions :
1-Name the four taste
types mentioned in the passage and give an example of each .
