How to use active voice?

The active voice is the "normal" voice.  In the passive voice, the object receives               the action  of the verb:

 A cti ve Fo rm:

Thing doing action verb

thing receiving action

Examples:

Nadech sings a song.

How to use passive voice?

The passive voice is less usual. In the passive voice, the subject receives the action of the verb:

Passive voice is used when the focus is on the action. It is not important or not known, however, who or what is performing the action.Example: The song is sung by them.

Thing receiving

Brain The brain is the most important organ in our bodies. It controls the body and makes sure that it works properly. The human brain is divided into two halves and each half has a different responsibility. The right-hand side controls imagination, and artistic and musical talent. The left-hand side controls memory, speaking, reading, writing and mathematical ability.

heart The heart is a muscle inside

your chest. It sends blood around the body, which provides the body with oxygen and nutrients it needs. The heart is also like a pump. It takes blood from the body and sends it to the lungs. The heart beats when it fills with blood and contracts to send the blood out moving around your body.

lungsThe lungs are one of the

largest organs in the body. They are located in the chest and make up part of the respiratory system, which is a group of organs and tissue that allow us to breath. They allow the body to breath oxygen from the air and help get rid of carbon dioxide (a waste gas that can be toxic) from the body.

liver The liver is the largest

solid organ in the body. It cleans the blood by taking toxins out. It also makes an important liquid called bile, which helps the body absorb fat into the bloodstream. This yellowish liquid is stored until the body needs to use it to digest fat. The liver also stores energy in the form of a sugar.

kidneys The kidneys are a pair of

organs that clean waste, which is what the body does not need, out of the blood. The waste is passed out of the body as urine. Kidneys also make important hormones and control blood pressure. They also control the levels of water, salts, and minerals in the body.

stomachYour stomach is a stretchy

bag of muscle that is very important in digesting food. It is part of your gastrointestinal system. When you have chewed and swallowed your food, your stomach mixes and churns it like a blender, then adds stomach acid and enzymes, which speed digestion up.

small IntestineThe small intestine (small

bowel) is about 20 feet long and about an inch in diameter. Its job is to absorb most of the nutrients from what we eat and drink. Velvety tissue lines the small intestine, which is divided into the duodenum, jejunum, and ileum.

large IntestineThe large intestine (colon or

large bowel) is about 5 feet long and about 3 inches in diameter. The colon absorbs water from wastes, creating stool. As stool enters the rectum, nerves there create the urge to defecate.
