MINTA CONTOH TEXT REPORT TENTANG NYAMUK

Mosquitoes are insects in the family Culicidae. They have a pair of scaled wings, a pair of halteres, a slender body, and long legs. The females of most mosquito species suck blood (hematophagy) from other animals, which has made them the most deadly disease vector known, killing millions of people over thousands of years and continuing to kill millions per year by the spread of diseases.

Length varies but is rarely greater than 16 mm (0.6 inch), and weight up to 2.5 mg (0.04 grain). A mosquito can fly for 1 to 4 hours continuously at up to 1–2 km/h travelling up to 10 km in a night. Most species are nocturnal or crepuscular (dawn or dusk) feeders. During the heat of the day most mosquitoes rest in a cool place and wait for the evenings. They may still bite if disturbed. Mosquitos are adept at infiltration and have been known to find their way into homes via deactivated air conditioning units.

1. The Boy who cried “Wolf”

There was once a shepherd-boy who kept his flock at a little distance from the village. Once he thought he would play a trick on the villagers and have some fun at their expense. So he ran toward the village crying out, with all his might,--

"Wolf! Wolf! Come and help! The wolves are at my lambs!"

The kind villagers left their work and ran to the field to help him. But when they got there the boy laughed at them for their pains; there was no wolf there.

Still another day the boy tried the same trick, and the villagers came running to help and got laughed at again. Then one day a wolf did break into the fold and began killing the lambs. In great fright, the boy ran for help. "Wolf! Wolf!" he screamed. "There is a wolf in the flock! Help!"

The villagers heard him, but they thought it was another mean trick; no one paid the least attention, or went near him. And the shepherd-boy lost all his sheep.

Moral value:

That is the kind of thing that happens to people who lie: even when they tell the truth no one believes them.

2.

Once there were two him thin  goats. Both of them were hungry. They were tied together with a brown rope. They wanted to eat the green leaves from two separated bushes. One bush was on the left. The other bush was on the right.

The goats thought they could do everything on their own. The first goat wanted to go to the bush on the left, but the second goat wanted to go to the bush on the right. However, the rope was short. They tried but they could not reach they bushes. They were sad.

Then, the goats decided to work together. First, they are the leaves of the bush on the right. Then, ate the leaves on the left. The leaves were delicious. They were happy.

 

3.

It was a warm day in March. I was very excited. The day had finally come. I was in the rowing team for the Olympics. I got up very early and exercised as always. Then after breakfast I drove to Drummoyne. My team arrived and at last it was time to start.Ready, set and the starting gun went off. We began in the third position and were slowly moving closer. There they were. We could see the second boat and then we did it.We moved past. My arms were aching. My whole body was sore but we all rowed harder.The first boat was just in front  I saw a dark shadow near the boat. I looked again. What was it? I was sure  it was the shape of a cigar. ‘Oh my  God’,  I thought, ‘I must be seeing things. A shark in Parramata River? Impossible!’Just then I pulled my oar out of the water. ‘Oh no, why only half?’ I thought. Then I knew. I shouted to my team, ‘Shark! Shark!’ and suddenly we forgot the race. We rowed faster than ever back to shore. We made it. Phew, we were safe!

Rabbits are small mammals in the family Leporidae of the order Lagomorpha, found in several parts of the world. There are seven different genera in the family classified as rabbits, including the European rabbit (Oryctolagus cuniculus), Cottontail rabbit (genus Sylvilagus; 13 species), and the Amami rabbit (Pentalagus furnessi, endangered species on Amami Ōshima, Japan). There are many other species of rabbit, and these, along with pikas and hares, make up the order Lagomorpha.

 

  • appearence

The long ears of rabbits are most likely an adaptation for detecting predators. In addition to their prominent ears, which can measure more than 10 cm (4 in) long, rabbits have long, powerful hind legs and a short tail. Each foot has five digits (one reduced); rabbits move about on the tips of the digits in a fashion known as digitigrade locomotion. Full-bodied and egg-shaped, wild rabbits are rather uniform in body proportions and stance. The smallest is the pygmy rabbit (Brachylagus idahoensis), at only 20 cm in length and 0.4 kg (0.9 pound) in weight, while the largest grow to 50 cm and more than 2 kg. The fur is generally long and soft, and its color ranges through shades of brown, gray, and buff. Exceptions are the black Amami rabbit (Pentalagus furnessi) of Japan and two black-striped species from Southeast Asia. The tail is usually a small puff of fur, generally brownish but white on top in the cottontails (genus Sylvilagus) of North and South America.

 

  • food

Rabbits are herbivores who feed by grazing on grass, forbs, and leafy weeds. In addition, their diet contains large amounts of cellulose, which is hard to digest. Rabbits solve this problem by passing two distinct types of feces: hard droppings and soft black viscous pellets, the latter of which are immediately eaten. Rabbits reingest their own droppings (rather than chewing the cud as do cows and many other herbivores) in order to fully digest their food and extract sufficient nutrients.

 

  • habitat

Rabbits are ground dwellers that live in environments ranging from desert to tropical forest and wetland. Their natural geographic range encompasses the middle latitudes of the Western Hemisphere. In the Eastern Hemisphere rabbits are found in Europe, portions of Central and Southern Africa, the Indian subcontinent, Sumatra, and Japan. The European rabbit (Oryctolagus cuniculus) has been introduced to many locations around the world, and all breeds of domestic rabbit originate from the European.

 

  • behavior

While the European rabbit is the best-known species, it is probably also the least typical, as there is considerable variability in the natural history of rabbits. Many rabbits dig burrows, but cottontails and hispid hares do not. The European rabbit constructs the most extensive burrow systems, called warrens. Nonburrowing rabbits make surface nests called forms, generally under dense protective cover. The European rabbit occupies open landscapes such as fields, parks, and gardens, although it has colonized habitats from stony deserts to subalpine valleys. It is the most social rabbit, sometimes forming groups in warrens of up to 20 individuals. However, even in European rabbits' social behaviour can be quite flexible, depending on habitat and other local conditions, so that at times the primary social unit is a territorial breeding pair. Most rabbits are relatively solitary and sometimes territorial, coming together only to breed or occasionally to forage in small groups. During territorial disputes rabbits will sometimes “box,” using their front limbs. Rabbits are active throughout the year; no species is known to hibernate. Rabbits are generally nocturnal, and they also are relatively silent. Other than loud screams when frightened or caught by a predator, the only auditory signal known for most species is a loud foot thump made to indicate alarm or aggression. Notable exceptions are the Amami rabbit and the volcano rabbit of Mexico, which both utter a variety of calls.

Instead of sound, scent seems to play a predominant role in the communication systems of most rabbits; they possess well-developed glands throughout their body and rub them on fixed objects to convey group identity, sex, age, social and reproductive status, and territory ownership. Urine is also used in chemical communication. When danger is perceived, the general tendency of rabbits is to freeze and hide under cover. If chased by a predator, they engage in quick, irregular movement, designed more to evade and confuse than to outdistance a pursuer. Skeletal adaptations such as long hind limbs and a strengthened pelvic girdle enable their agility and speed (up to 48 km [30 miles] per hour).

Contoh Teks Report tentang Tiger:

The tiger (Panthera tigris) is a member of the Felidae family; the largest and the most powerful of the four "big cats" in the genus Panthera.[4] Native to much of eastern and southern Asia, the tiger is an apex predator and an obligate carnivore. Reaching up to 4 metres (13 ft) in total length and weighing up to 300 kilograms (660 pounds), the larger tiger subspecies are comparable in size to the biggest extinct felids.[5][6] Aside from their great bulk and power, their most recognizable feature is the pattern of dark vertical stripes that overlays near-white to reddish-orange fur, with lighter underparts. The largest subspecies of tiger is the Siberian tiger.

Highly adaptable, tigers range from the Siberian taiga, to open grasslands, to tropical mangrove swamps. They are territorial and generally solitary animals, often requiring large contiguous areas of habitat that support their prey demands. This, coupled with the fact that they are endemic to some of the more densely populated places on earth, has caused significant conflicts with humans. Of the nine subspecies of modern tiger, three are extinct and the remaining six are classified as endangered, some critically so. The primary direct causes are habitat destruction and fragmentation, and hunting. Their historical range, which once reached from Mesopotamia and the Caucasus through most of South and East Asia, has been radically reduced. While all surviving species are under formal protection, poaching, habitat destruction and inbreeding depression continue to be threats.

Nonetheless, tigers are among the most recognizable and popular of the world's charismatic megafauna. They have featured prominently in ancient mythology and folklore, and continue to be depicted in modern films and literature. Tigers appear on many flags and coats of arms, as mascots for sporting teams, and as the national animal of several Asian nations.

REPORT


Teks Report adalah teks yang menggambarkan sesuatu secara umum.

Generic Structure: General Classification - Description.
Tenses yang digunakan adalah 'Present Tense'.

Contoh Teks Report:

 

1.

Library

A library is a place which collects records of what people have thought and done.(Ini adalah General Classification).

It preserves those records, and it ,makes them available to us, so that we can learn about many things. In the world of library, we can entertain ourselves, teach ourselves, and be inspired by the ideas that we might never have dreamed ot otherwise.(Ini adalah 'Description')
         A library has many sections. Commonly, a library has a reading room, a catalogue section, a newspaper and magazine section, books section, and a librarian desk which deals with book circulation. The books are classified based on the subjects, such as fiction, science, psychology, etc. They are arranged on the bookshelves.(Ini adalah 'Description').
 

2.

Goannas

Goannas are large Australian lizards which belong to the reptile family.Goannas are yellowish-brown in colour and grow to about a metre in length.They live in burrows and eat insects, lizards, mice, eggs, and flesh of dead animals. To breed, the female goanna lays about six eggs in a termite mound.

3.

Fax Machine

 

Fax, the short term for facsimile is a telecommunications technology used to transfer copies (facsimiles) of documents, especially using affordable devices operating over the telephone network. The word telefax, short for telefacsimile, for "make a copy at a distance", is also used as a synonym. The device is also known as a telecopier in certain industries. When sending documents to people at large distances, faxes have a distinct advantage over postal mail in that the delivery is nearly instantenous, yet its disadvantages in quality and its proprietary format have relegated it to a position beneath email as the prevailing form of electronic document tranferral.

 

4.

What is a Whale?

 

Whales are large, magnificent, intelligent, aquatic mammals. They breathe air through blowhole(s) into lungs (unlike fish who breathe using gills). Whales have sleek, streamlined bodies that move easily through the water. They are the only mammals, other than manatees (seacows), that live their entire lives in the water, and the only mammals that have adapted to life in the open oceans

Like all mammals:

  • Whales breathe air into lungs,
  • Whales have hair (although they have a lot less than land mammals, and have almost none as adults),
  • Whales are warm-blooded (they maintain a high body temperature),
  • Whales have mammary glands with which they nourish their young,
  •  Whales have a four-chambered heart.

The biggest whale is the blue whale, which grows to be about 94 feet (29 m) long - the height of a 9-story building. These enormous animals eat about 4 tons of tiny krill each day, obtained by filter feeding through baleen. Adult blue whales have no predators except man.

The smallest whale is the dwarf sperm whale which as an adult is only 8.5 feet (2.6 m) long.

5.

Plants

Plants are living beings. They need food, water and air for survival.

Plants derive their food from the earth and the air. If you look at their roots, you will find that ends of these roots are like fine fibers. We call them root-hairs. They absorb water and minerals, then transport them upwards to the leaves through the trunk and the branches. It is the leaves which prepare the food.

The green material, chlorophyll, prepares the food like a machine. It converts the carbon dioxide taken from the air and water from the ground into sugar with the help of sunlight. This chemical reaction is called photosynthes. In fact, the chlorophyll takes energy from the sunlight and uses it to synthesize the hydrogen from water and carbon from carbon dioxide for making sugar. This reaction also gives out oxygen and water which are excreted by the leaves.

6

Rafflesia

Rafflesia is a genus of parasitic flowering plants. It was discovered in the Indonesian rain forest by an Indonesian guide working for Dr. Joseph Arnold in 1818, and named after Sir Thomas Stamford Raffles, the leader of the expedition. It contains approximately 26 species (including four incompletely characterized species as recognized by Meijer 1997), all found in southeastern Asia, on the Malay Peninsula, Borneo, Sumatra and Kalimantan, West Malaysia, and the Philippines. The plant has no stems, leaves or true roots. It is an endoparasite of vines in the genus Tetrastigma (Vitaceae), spreading its root-like haustoria inside the tissue of the vine. The only part of the plant that can be seen outside the host vine is the five-petaled flower. In some species, such as Rafflesia arnoldii, the flower may be over 100 cm in diameter, and weigh up to 10 kg. Even the smallest species, R. manillana, has 20 cm diameter flowers. The flowers look and smell like rotting meat, hence its local names which translate to "corpse flower" or "meat flower" (but see below). The vile smell that the flower gives off attracts insects such as carrion flies, which transport pollen from male to female flowers. Little is known about seed dispersal. However, tree shrews and other forest mammals apparently eat the fruits and disperse the seeds. Rafflesia is an official state flower of Sabah in Malaysia, as well as for the Surat Thani Province, Thailand.
