What is Explanation?
1. 1. Definition and purposes of Explanation Explanation is a text which tells processes relating to forming of natural, social, scientific and cultural phenomena. Explanation text is to say ‘why’ and ‘how’ of the forming of the phenomena. It is often found in science, geography and history text books.
1. 2. Generic structure of Explanation General statement; stating the phenomenon issues which are to be explained.Sequenced explanation; stating a series of steps which explain the phenomena.
1. 3. Language Feature Featuring generic participant; sun, rain, etcUsing chronological connection; to begin with, next, etcUsing passive voice patternUsing simple present tense
1. 4. Examples Example of Explanation Text
1. A.
Tsunami The term of “tsunami” comes from the Japanese which means harbour (“tsu”) and wave (“nami”). A tsunamigk is a series of waves generated when water in a lake or the sea is rapidly displaced on a massive scale. A tsunami can be generated when the sea floor abruptly deforms and vertically displaces the overlying water. Such large vertical movements of the earth’s crust can occur at plate boundaries. Subduction of earthquakes are particularly effective in generating tsunamis, and occur where denser oceanic plates slip under continental plates. As the displaced water mass moves under the influence of gravity to regain its equilibrium, it radiates across the ocean like ripples on a pond. Tsunami always bring great damage. Most of the damage is caused by the huge mass of water behind the initial wave front, as the height of the sea keeps rising fast and floods powerfully into the coastal area.
1 B. What is
honey? How do honey bees make honey?
Honey is a sweet, thick sugary solution
made by bees. The composition of honey consists of varying proportions of
fructose, glucose, water, oil and special enzymes produced by bees. (Glucose and fructose are types of
suger)
The
first step in making honey begins when field bees fly from flower to flower
collecting the sweet juices or nectar that a flower provides. With their
tongues, the field bees suck out the nectar and store it in sacs within their
bodies. After filling their sacs with these sweet juices, the field bees fly
back to their bee hive and regurgitate the stored nectar into the mouths of
house bees.
These
house bees are assigned the job of adding enzymes from their bodies to the
nectar. The enzymes cause the water in the nectar to evaporate-thereby turning
the nectar into honey. Lastly, the nectar is stored in a cell of a honeycomb.
Overtime, the nectar ripens and becomes honey.
The
buzz on honey...
- Honey is one of the easiest foods to digest.
- Honey is used in many cough syrups because its smooth, thick texture soothes throats.
- As a result of honey's unique ability to readily absorb air, it is often used as a moistening agent in baking.
- Honey comes in all types of colors and flavors. The color and flavor of honey depends on the how old the honey is and the kind of flower that the nectar was extracted from.
