Human body is made up of countless millions of cells. Food is needed to build up new cells and replace the worn out cells. However, the food that we take must be changed into substance that can be carried in the blood to the places where they are needed, this process is called digestion.
The first digestive process takes places 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, mixed and moving the food on wards.
In a few hours, the food changes into acids. There are soon absorbed by the villi (microscopic branch projections from the intestine walls) walls and passed into the bloodstream.

a good process of digestive system will help our body becoming healthier.
everybody must conduct the processes of digestive system well.
the digestive system is needed if we are eating the food instantly.
no one concerned with the process of digestive system for their health.

Acid rain is rain that is highly acidic because of sulfur oxides, nitrogen oxides, and other air pollutants dissolved in it. Normal rain is slightly acidic, with a pH of 6. Acid rain may have a pH value as low as 2.8.
Acid rain can severely damage both plant and animal life. Certain lakes, for example, have lost all fish and plant life because of acid rain.
Acid rain comes from sulfur in coal and oil. When they burn, they make sulfur dioxide (SO₂). Most sulfur leaves factory chimneys as the gaseous sulfur dioxide (SO₂) and most nitrogen oxides (NO ᴏr NO₂), both of which are gasses. The gasses may be dry deposited-absorbed directly by the land, by lakes or by the surface vegetation. If they are in the atmosphere for anytime, the glasses will oxidize (gain an oxygen atom) and go into solution as acids. Sulfuric acid (H₂SO₄) and the nitrogen oxides will become nitric acid (HNO₃). The acids usually dissolve in cloud droplets and may travel great distances before being precipitated as acid rain. Catalysts such as hydrogen peroxide, ozone, and ammonium help promote the formation of acid in clouds. More ammonium (NH₄) can be formed when some of the acids are partially neutralized by airborne ammonia (NH₃).
Acidification increases with the number of active hydrogen (H⁺) ions dissolved in acid. Hydrocarbons emitted by, for example, car exhaust will react in sunlight with nitrogen oxides to produce ozone. Although it is invaluable in the atmosphere, low-level ozone causes respiratory problems and also hastens the formation of acid rain. When acid rain falls on the ground it dissolves and liberates heavy metals and aluminum (Al). When it is washes into lakes, aluminum irritates the outer surfaces of many fish. As acid rain falls or drains into the lake the pH of the lake falls. Forests suffer the effect of acid rain through damage to leaves, through the loss of vital nutrients, and through the increased amounts of toxic metals liberated by acid, which damage roots and soil microorganisms.
The acid of normal rain is…. then the acid rain.

higher
severer
lower
denser

Dear Betty,
I’m writing to you concerning of my last day in Yogyakarta. I just got back from Borobudur, the wonderful temple I’ve ever seen. The weather is fine. We are now staying in a hotel. It’s not far from Malioboro. We are treated well here. It has many excellent staff who serve the customers. We plan to go around Malioboro after the children take a short nap. We want to enjoy having “lesehan” there. It is a kind of restaurant but we sit on the ground.
Many kinds of local handicraft are sold along Malioboro streets. Both domestic and foreign tourist are interested in them. I want to buy some as souvenir.
Don’t worry, I’ll also buy you the most interesting one.
