Answer these questions below based on the text given correctly.
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 often disastrous 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.

Recycling is a collection, processing, and reuse of materials that would otherwise be thrown away. Materials ranging from precious metals to broken glass, from old newspapers to plastic spoons, can be recycled. The recycling process reclaims the original material and uses it in new products. In general, using recycled materials to make new products costs less and requires less energy than using new materials. Recycling can also reduce pollution, either by reducing the demand for high-pollution alternatives or by minimizing the amount of pollution produced during the manufacturing process. Paper products that can be recycled include cardboard containers, wrapping paper, and office paper. The most commonly recycled paper product is newsprint. In newspaper recycling, old newspapers are collected and searched for contaminants such as plastic bags and aluminum foil. The paper goes to a processing plant where it is mixed with hot water and turned into pulp in a machine that works much like a big kitchen blender. The pulp is screened and filtered to remove smaller contaminants. The pulp then goes to a large vat where the ink separates from the paper fibers and floats to the surface. The ink is skimmed off, dried and reused as ink or burned as boiler fuel. The cleaned pulp is mixed with new wood fibers to be made into paper again. Experts estimate the average office worker generates about 5 kg of wastepaper per month. Every ton of paper that is recycled saves about 1.4 cu m ( about 50 cu ft) of landfill space. One ton of recycled paper saves 17 pulpwood trees ( trees used to produce paper ).

Human body is made up of countless millions of cells. Food is needed to built up
new cells and replace the worn out cells. However, the food that we take must be
changed into substances that can be carried in the blood to the places where they
are needed. This process is called digestion.
The first digestive process takes place in the mouth. The food we eat is broken up
into small pieces by the action of teeth, mixed with saliva, a juice secreted by glands
in the mouth. Saliva contains digestive juice which moisten the food, so it can be
swallowed easily.
From the mouth, food passes through the esophagus (the food passage) into the
stomach. Here, the food is mixed with the juices secreted by the cells in the stomach
for several hours. Then the food enters the small intestine. All the time the muscular
walls of the intestine are squeezing, mixing and moving the food onwards.
In a few hours, the food changes into acids. These are soon absorbed by the villi
(microscopic branch projections from the intestine walls) and passed into the
bloodstream.
5. What is the text about?
A. The digestive system
B. The digestive juice
C. The method of the digestive system
D. The process of intestine work
E. The food substances
6. How can we swallow the food easily?
A. The food changes into acids absorbed by the villi.
B. The food must be digested first through the process.
C. The food is directly swallowed through esophagus into the stomach.
D. The food is mixed with the juices secreted by the cells in the stomach.
E. The food we take must be changed into substances carried in the blood to
the places.
7. From the text above, we imply that ....
A. a good process of digestive system will help our body becoming healthier.
B. no one concerned with the process of digestive system for their health.
C. the digestive system is needed if we are eating the food instantly.
D. every body must conduct the processes of digestive system well.
E. the better we digest the food we eat, the healthier we will be.
8. Human body is made up of countless millions of cells. (Paragraph 1)
The phrase made up means ....
A. Produced
B. Managed
C. Arranged
D. Completed
E. Constructed

Have you ever wondered how people get chocolate from? In this article we’ll
enter the amazing world of chocolate so you can understand exactly what you’re
eating. Chocolate starts with a tree called the cacao tree. This tree grows in equatorial
regions, especially in places such as South America, Africa, and Indonesia. The cacao
tree produces a fruit about the size of a small pine apple. Inside the fruit are the
tree’s seeds, also known as cocoa beans.
The beans are fermented for about a week, dried in the sun and then shipped to
the chocolate maker. The chocolate maker starts by roasting the beans to bring out
the flavour. Different beans from different places have different qualities and flavor,
so they are often sorted and blended to produce a distinctive mix. Next, the roasted
beans are winnowed. Winnowing removes the meat nib of the cacao bean from its
shell. Then, the nibs are blended. The blended nibs are ground to make it a liquid.
The liquid is called chocolate liquor. It tastes bitter. All seeds contain some amount
of fat, and cacao beans are not different. However, cacao beans are half fat, which
is why the ground nibs form liquid. It’s pure bitter chocolate.
9. The text is about ....
A. the cacao tree
B. the cacao beans
C. the raw chocolate
D. the making of chocolate
E. the flavour of chocolate
10. The third paragraph focuses on ....
A. the process of producing chocolate
B. how to produce the cocoa flavour
C. where chocolate comes from

has the closest meaning to ....
A. Arranged
B. Combined
C. Separated
D. Distributed
E. Organized
12. How does the chocolate maker start to make chocolate?
A. By fermenting the beans.
B. By roasting the beans

What is photosynthesis? Photosynthesis is a food-making process that occurs in
green plants. It is the chief function of leaves. The word photosynthesis means
putting together with light. Green plants use energy from light to combine
carbon dioxide and water to make sugar and other chemical compounds.
How is the light used in photosynthesis?
The light used in photosynthesis is absorbed by a green pigment called chlorophyll. Each food-making cell in a plant leaf contains chlorophyll in small
bodies called chloroplasts. In chloroplast, light energy causes water drawn form
the soil to split into hydrogen and oxygen.
What are the steps of photosynthesis process? Let me tell you the process of
photosynthesis, in a series of complicated steps, the hydrogen combines with
carbon dioxide from the air, forming a simple sugar. Oxygen from the water
molecules is given off in the process. From sugar together with nitrogen,
sulphur, and phosporus from the soil-green plants can make starch, fat, protein,
vitamins, and other complex compounds essential for life. Photosynthesis
provides the chemical energy that is needed to produced these compounds.
13. What step after the hydrogen combines with carbon dioxide from the air ...
A. Photosynthesis provides the chemical energy that is needed to produced
these compounds.
B. Water drawn form the soil to split into hydrogen and oxygen.
C. Food-making process that occurs in green plants.
D. Phosporus from the soil-green plants can make starch, fat, protein,
vitamins, and other complex compounds essential for life.
E. Oxygen from the water molecules is given off in the process.
14. What are photosynthesis need ....
A. Water, light, oxygen, worm
B. Soil, chlorophyll, sun, human
C. Bug, air, oxigen, food
D. Light, Carbon dioxide, humus
E. Candle, vitamins, hydrogen
15. What the product of photosynthesis ....
A. Sugar
B. Food and O2
C. Root
D. Food
