CINDERELLA
Once upon a time, there was a young girl named Cinderella. She lived with her step mother and two step sisters.
The step mother and sisters were conceited and bad tempered. They treated Cinderella very badly. Her step mother made Cinderella do the hardest works in the house; such as scrubbing the floor, cleaning the pot and pan and preparing the food for the family. The two step sisters, on the other hand, did not work about the house. Their mother gave them many handsome dresses to wear.
One day, the two step sister received an invitation to the ball that the king’s son was going to give at the palace. They were excited about this and spent so much time choosing the dresses they would wear. At last, the day of the ball came, and away went the sisters to it. Cinderella could not help crying after they had left.
“Why are crying, Cinderella?” a voice asked. She looked up and saw her fairy godmother standing beside her, “because I want so much to go to the ball” said Cinderella. “Well” said the godmother,”you’ve been such a cheerful, hardworking, uncomplaining girl that I am going to see that you do go to the ball”.
Magically, the fairy godmother changed a pumpkin into a fine coach and mice into a coachman and two footmen. Her godmother tapped Cinderella’s raged dress with her wand, and it became a beautiful ball gown. Then she gave her a pair of pretty glass slippers. “Now, Cinderella”, she said; “You must leave before midnight”. Then away she drove in her beautiful coach.
Cinderella was having a wonderfully good time. She danced again and again with the king’s son. Suddenly the clock began to strike twelve, she ran toward the door as quickly as she could. In her hurry, one of her glass slipper was left behind.
A few days later, the king’ son proclaimed that he would marry the girl whose feet fitted the glass slipper. Her step sisters tried on the slipper but it was too small for them, no matter how hard they squeezed their toes into it. In the end, the king’s page let Cinderella try on the slipper. She stuck out her foot and the page slipped the slipper on. It fitted perfectly.
Finally, she was driven to the palace. The king’s son was overjoyed to see her again. They were married and live happily ever after.

Notes on Generic Structure of Narrative Text
Orientation: it means to introduce the participants or the characters of the story with the time and place set. Orientation actually exists in every text type though it has different term. In this story, the first paragraph is clearly seen to introduce the participants of the Cinderella Story. They were Cinderella her self as the main character of the story, her step mother which treated Cinderella badly, and her steps sister which supported her mother to make Cinderella was treated very badly. Cinderella was introduced as a hero in this story. She struggled against the bad treatment from her step mother and sisters.
Complication: it is such the crisis of the story. If there is not the crisis, the story is not a narrative text. In a long story, the complication appears in several situations. It means that some time there is more then one complication. In this Cinderella story, we can see clearly that there are Major Complication and Minor Complication.
The second paragraph is the major complication of this Cinderella story. Cinderella got bad treatment from her stepmother. It is the bad crisis which drives into several minor complications which Cinderella has to overcome.
Resolution: it is the final series of the events which happen in the story. The resolution can be good or bad. The point is that it has been accomplished by the characters. Like complication, there are Major Resolution and Minor Resolution.
In the last paragraph, it is said that finally Cinderella lived happily. It is the happy resolution of the bad treatment.

 

Why Eiffel Tower was Built

If we talk about the Wonders of the World buildings, then we will see Eiffel Tower as one of them. However many of us do not know the tower’s past history on why it was build. Everything has the reasonable background, especially for the tower which is to be one of the most recognized buildings in the world.

Primarily, the Eiffel Tower was built for the World Exhibition. It was called Paris Exposition in 1889. The exhibition was organized to celebrate the 100th anniversary of the French Revolution. The purpose of building Eiffel Tower in such structure was to show to the world France’s advancement of technology and beauty. The Eiffel Tower was designed by Gustave Eiffel. It seemed that then the name of the tower was derived from the designer’s last name, “Eiffel”

Another reason on why the tower was built was for scientific progress. Although few realized it, the Eiffel Tower would become the prominent structure in terms of science and technology. Many experiment with temperature, pressure and pendulums were performed atop the unique famous building. Additionally the Eiffel Tower was used for radio transmission tower. Many experiments were conducted atop the Eiffel Tower for radio transmission advancement. Once the Eiffel Tower was proposed to be demolished but it was spared because the tower had the promising future as a radio tower.

Generic Structure of Explanation Text

The best discourse on how and what is explanation text is answering the question word “how” and “why”. Such question words need detail explanation on it relates. However, explanation text is written in narrative style and not instructional. If it is written for the purpose of instruction, then the text genre will be labeled as PROCEDURE.

From the above example of explanation text, we see that it has the generic structure as follow:

• General Statement; the introduction of the passage on why the Eiffel Tower was built.

Sequenced Explanation; this is the main element of explanation text. This explanation is explored to answer the “why” or “how” question introduced in the general statement. From the example above, the text was written to explain why, not how, the Eiffel Tower was built. Then it elaborates the reasons. First is for the show case and the second is for scientific and technological purposes.

 

 

Nuclear power is generated by using uranium which is a metal mined in various part of the world. The first large scale of nuclear power station was opened at Calder Hall in Cumbria, England in 1956.
Some military ships and submarines have nuclear power plant for engine. Nuclear power produces around 11% of the world's energy needed, and produces huge amounts of energy. It cause no pollution as we would get when burning fossil fuels. The advantages of nuclear plant are as follow:

• It costs about the same coal, so it is not expansive to make.
• It does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect.
• It produces huge amounts of energy from small amount of uranium.
• It produces small amount of waste.
• It is reliable.

On the other hand, nuclear power is very, very dangerous. It must be sealed up and buried for many years to allow the radioactivity to die away. Furthermore, although it is reliable, a lot of money has to be spent on safety because if it does go wrong, a nuclear accident ca be a major accident.
People are increasingly concerned about this matter. In the 1990's nuclear power was the fastest growing source of power in many parts of the world.

Discussion is a process to find the meet point between two different ideas. It is important to to get the understanding between the two differences. In many social activities, discussion is the effective way to calm down any friction and difference in thought, perception and recommendation.
This example of discussion text present the two poles, between the advantage and disadvantage of using nuclear plant to fulfill the energy needed. It is a case which need to be talked and discussed from two points. They are represented in the generic structure which is used:
Stating the Issue: In the first paragraph, it is stated that using nuclear power can be the choice in fulfilling the needed energy.
Supporting Point: In the second paragraph, it is presented the advantages of nuclear power plant to be used as the source of the world's energy needed
Contrastive Point: The third paragraph shows the balance. It gives the contradictory idea in using nuclear power plant as the resource of energy.
Recommendation: This text is ended with a similar recommendation on how people should concern in the matter of nuclear energy.

Minta tolong dong tentang pembahasan expression love , sadness and embarrassment beserta contoh yang lengkap . makasih :)

Expressing Love

Love is a complicated emotion and without really understanding love and its secrets many relationships get into trouble and sometimes the damage can be hard to repair.   Embarrassment is an emotional state experienced upon having a socially or professionally unacceptable act or condition witnessed by or revealed to others. Usually some amount of loss of honour or dignity is involved, but how much and the type depends on the embarrassing situation. It is similar to shame, except that shame may be experienced for an act known only to oneself. Also, embarrassment usually carries the connotation of being caused by an act that is merely socially unacceptable, rather than morally wrong.   The Sad Expression A. The crying baby face shows elements of the sad expression: narrowed eyes and raised cheeks, eyebrows pulled together, lip corners pulled down, chin boss pushed up, but also includes lateral lip stretching and has no raising of the eyebows in the center of the forehead . B. A suffering child shows a typical sad expression, with narrowed eyes and raised cheeks, eyebrows pulled together and raised in the center of forehead forming wrinkles in the glabella, and a slightly pushed up chin boss. The lips may be slightly pulled laterally and downwards. C. This depiction of sadness shows the downturned lip corners and pushed up chin boss consistent with a sad expression. Also, the eyes are narrowed, but any actions in the brow area are obscured. Her posture, gaze direction, and head orientation help convey the overall sad expression.

Matematika Kelas 8

 

 

Empat tahun yang lalu umur seorang ayah 5 kali umur anak pertamanya. Tiga tahun mendatang umur ayah itu tiga kali umur anak tersebut. Berapa umur ayah itu sekarang?

Jawab

Misal umur anak sekarang = x dan umur ayah = y

4 tahun lalu          Sekarang                    3 tahun akan datang

 x - 4                            x                                   x + 3

y - 4                             y                                    y + 3

y - 4 = 5(x - 4)                                                    y + 3 = 3(x + 3)

y - 4 = 5x - 20                                                     y + 3 = 3x +9

y - 5x = - 20 + 4                                                    y - 3x = 9 - 3

y - 5x = - 16 ....... (1)                                              y - 3x = 6 ......(2)

 

Dari (1) dan (2) diperoleh sbb:

 y - 5x = - 16

 y - 3x = 6   -

    - 2x  = - 22

        x = 11 .............> umur anak

nilai x = 11 disubstitusikan pada pers (1) diperoleh

y - 5x = - 16

y - 55 = - 16

     y  = 55 - 16

     y = 39 ..............> umur ayah

Jadi umur anak sekarang = 11 tahun dan umur ayah sekarang = 39 tahun

Demikian semoga jelas.

Bahasa Inggris Kelas 9

minta tolong kasih contoh karangan deskripsi...maksi sebelumnya

Terima Kasih atas pertanyaannya.

Here are the examples of report texts :

 

Bees are small creatures. They have no bones, but have six legs. Insects live everywhere: in our garden, in the fields and in many other places. Insect are not always bad as sometimes people. Bad insects are for instance flies, cockroaches and mosquitoes. Such insect are not only bad, but sometimes also dangerous. Files like to live on rubbish and other dirty places. They may cause disease such as typhus, cholera etc. a certain type of mosquito brings malaria.

Bees are not usually dangerous, except you make them angry. If you disturb bees, they will be angry. And if they are angry they will fly to attack you wherever you go. This is very dangerous.

The tiger is the largest member of the cat family. There were once eight sub species: Caspian, Bengal, Indochinese, Chinese, Siberlan, Sumatran Javanese and Balinese. Three sub species are extinct, while the rest are endangered, so we have to protect them.

Tiger have reddish skin, a white belly and white and black tail. The head, body and the taill have black brown and grey strips. Tigers usually eat deer, bufalloes and rabbits.

Tigers are now protected species, but the hunters continue to kill them for their skins. In some parts of Asia, some parts of boy tigers are used as medicines.

DINOSAURS

Dinosaurs were a type of lizards. They lived from about 230 million to about 65 million are ago. In 1842, Sir Richard Owen created the word dinosaur. It came from Greek words inos, meaning "terrible" and sauros, meaning "lizard". Dinosaurs lived on earth for about 140 million years.

During the dinosaurian era, the days were short. The sun was not as hot as it is today. On earth there was only one big continent and one big ocean. The name of the continent was pangea all lands) and the name of the ocean was panthallassa (all seas).

There were many kinds of dinosaurs. Some of them were very big and some others were small. Some dinosaurs ate leaves and some others ate meat. Some dinosaurs could fly.

What happened to dinosaurs? Dinosaurs became extinct because there was a large comet getting the earth. The comet caused fire and it killed the trees. Dinosaurs could not eat because here were no trees on earth and finally they died and became extinct.

 

 

Here are the examples of descriptive texts :

 

Tourist guide

A person who guides visitors in the language of their choice and interprets the cultural and natural heritage of an area.

The guide will normally possess an area-specific qualification usually issued and/or recognised by the appropriate authority. Tourist Guides are representatives of the cities, regions and countries for which they are qualified. It depends largely on them if visitors feel welcome, want to stay longer or decide to come back. They therefore contribute considerably to the perception of the destination. Tourist Guides are able to help travellers understand the culture of the region visited and the way of life of its inhabitants. They have a particular role on the one hand to promote the cultural and natural heritage whilst on the other hand to help ensure its sustainability by making visitors aware of its importance and vulnerability.

BOROBUDUR

Borobudur, Hindu-Buddhist temple, near Magelang on the island of Java in Indonesia. Built in the 9th century under the Sailendra dynasty of Java, it was abandoned in the 11th century and partially excavated by archaeologists in the early 20th century.

Influenced by the Gupta architecture of India, the temple is constructed on a hill 46 m (150 ft) high and consists of eight step-like stone terraces, one on top of the other. The first five terraces are square and surrounded by walls adorned with Buddhist sculpture in bas-relief; the upper three are circular, each with a circle of bell-shaped stupas (Buddhist shrines). The entire edifice is crowned by a large stupa at the center of the top circle. The way to the summit extends through some 4.8 km (some 3 mil) of passages and stairways. The design of Borobudur, a temple-mountain symbolizing the structure of the universe, influenced temples built at Angkor, Cambodia. Borobudur was rededicated as an Indonesian national monument in 1983 following extensive reclamation, aided by the United Nations.
