Silkworms live for only two or
three days after laying eggs. About 36,000 to 50,000 eggs are laid, and these
are carefully stored at the silkworm farm until they are ready to hatch. The
eggs hatch into caterpillars, which feed on mulberry leaves. Soon, the
caterpillars are ready to spin their cocoons. Not all caterpillars can spin
silk cocoons. Only the caterpillars of a silkworm moth known as ‘Bombyx mari’
can do such spinning. This caterpillar has special glands which secrete liquid
silk through its lower lip. The liquid produced later hardens to form tine
strands.
The caterpillar makes its
cocoons using these strands. The threads on the outside of the cocoon are
rough, while those inside are soft and smooth.
Some fully-spun cocoons are
heated. This kills the pupa inside. The cocoons are then put into hot water to
loosen the fine threads. Finally, these threads are reeled off the cocoons.
The length of unbroken thread
produced by a single cocoon measures about one-and-a-half kilometers. Being
twisted together several of these threads make single woven materials.

A geyser is the
result of underground water under the combined conditions of high temperatures
and increased pressure beneath the surface of the earth. Since temperature
rises approximately 1 F for every sixty feet under the earth’s surface, and
pressure increases with depth, the water that seeps down in crack and fissures
until it reaches very hot rock in the earth interior becomes heated to
temperature in excess of 290 F. Because of the greater pressure, the water
shoots out of the surface in the form of steam and hot water. The result is a
geyser. In order to function, then a geyser must have a source of heat,
reservoir where water can be stored until the temperature rises to an unstable
point, an opening through which the hot water and steam can escape, and
underground channels for resupplying water after an eruption.
Favorable conditions for
geyser exist in some regions of the world including New Zealand, Iceland, and
the Yellowstone National Park area of the United States. The most famous geyser
in the world is Old Faithfull in Yellow Park. Old Faithfull erupts almost every
hour, rising to a height of 125 to 170 feet and expelling more than ten
thousand gallons during each eruption.

A kite is an
object which is made from a light material stretched over a frame. Due to its light
material a kite will lift off the ground and fly when it is tilted into the
wind.
A kite is uses wind to make it fly because it is heavier than air. When wind
travels over the surface of the kite, it is split into two streams of air. One
stream of the air goes over the kite while the second stream goes under the
kite.
The upper stream above the
kite. The lower stream hits the kite at a shallow angle and creates an area of
high pressure.
The high pressure area has a
pushing effect while the low pressure area has a pulling effect. The
combination of push and pull can creates enough force to lift the kite into the
air.
Kites have been known for thousand of years. They are used for military or
scientific purposes. Todays kites are much used for leisure and competition.
8. What media which use by kite to
fly?
A. Air

stream?
A. hits the kite at a shallow angle
B. creates an area of high pressure

A natural disaster is a terrible accident,
e.g. a great flood , a big fire, or an earthquake. It usually causes great
suffering and loss of a large sum of money. The causalities are injured or
died. Some people are homeless and need medical care.
Floods occur when the water of rivers,
lakes, or stream overflow their banks and pour out into the surrounding land.
Floods are caused by many different things. Often heavy rainstorms that last
for a brief time can cause a flood. But not all heavy storms are followed by
flooding. If the surrounding land is fl at and can absorb the water, no
flooding will occur. If, however, the land is hard and rocky, heavy rain cannot
be absorbed. Where the banks are low, a river may overflow and flood adjacent
lowland.
In many parts of the world floods are
caused by tropical storms called hurricanes or typhoons. They bring destructive
winds of high speed, torrents of rain, and flooding. When a flood occurs, the
destruction to the surrounding land can be severe. Whole villages and towns are
sometimes swept away by water pouring swiftly over the land. Railroad tracks
and buckles are uprooted from their beds. Highways are washed away.
When a building caught fire, the firemen
pitched in to help battle the blaze. Before the pumps were invented, people
formed bucket brigades to fight fires. Standing side by side, they formed a
human chain from the fire to nearby well or river. They passed buckets of water
from hand to hand to be poured on the flames.
The damage of fire did depend a great deal
on where it happened. In the country or a small village, only a single house
might burn down. But in crowded cities, fire often destroyed whole blocks and
neighborhoods before being controlled.

Tsunami
Tsunami occurs when major fault under the
ocean floor suddenly slips. The displaced rock pushes water above it like a
giant paddle, producing powerful water waves at the ocean surface. The ocean
waves spread out from the vicinity of the earthquake source and move across the
ocean until they reach the coastline, where their height increases as they
reach the continental shelf, the part of the earth crust that slopes, or rises,
from the ocean floor up to the land.
A tsunami washes ashore with
oftendisastrous effects such as severe flooding, loss of lives due to drowning
and damage to property.
A tsunami is a very large sea wave that is
generated by a disturbance along the ocean floor. This disturbance can be an
earthquake, a landslide, or a volcanic eruption. A tsunami is undetectable far
out in the ocean, but once it reaches shallow water, this fast traveling wave
grows very large.

All human beings eat food and make
use of the chemical energy in it, so do all other animals. Perhaps you wonder
where all that chemical energy comes from. Why doesn’t the food all get used
up?
The answer is that new food is being grown
as fast as old food is used to. It is the green plants that form the new food.
Animals either eat the plants or eat other animals that have eaten plants.
The green substance of plants is
chlorophyll. Chlorophyll can absorb sunlight. When it does so, it changes the
energy of the sun into chemical energy. The chemical energy present in sunlit
chlorophyll is used to combine dioxide in the air with water from the soil.
Starch and other complicated compounds are formed. These are high in chemical
energy obtained from the sunlit chlorophyll.
They make up the food on which mankind and
all other animals live. In the process of forming this food, some oxygen atoms
are left over. These are given off into the air by the plants. The whole
process is called photosynthesis.
Thus, plants use sunlight to from food and
oxygen to from carbon dioxide and water again. Plants change the sun’s energy
into chemical energy. And animals change the animal energy into kinetic and
heat energy.

C. Plants

While
the size of a lake or other body of water will vary with seasonal changes in
precipitation and show melt, it is not a significant flood unless such escapes
of water endanger land areas used by man like a village, city or other
inhabited area.
Floods
can also occur in rivers, when fl ow exceeds the capacity of the river channel,
particularly at bends or meanders. Flood often cause damage to homes and
businesses if they are placed in natural flood plains of rivers. While flood
damage van be virtually eliminated by moving away from and other bodies of
water, since time out of mind, people have lived and worked by the water to
seek the sustenance and capitalize on the gains of cheap and easy travel and
commerce by being near water. That humans continue to inhabit areas threatened
by flood damage is evidence that the perceived value of living near the water
exceeds the cost of repeated periodic flooding.

B. Place
