A brief introduction to the author of verb (abbreviation of verb)
Wang Xiaoyu, an Australian Chinese writer, has lived in Australia for nine years. I like Australian animals and plants very much. After the busy work of the editor-in-chief of Melbourne newspaper, I insist on writing thousands of words every day. Collected a lot of information about animals, and published the first Chinese version of Australian animal book-Portrait of Rare Animals-Australian Endemic Animals before the 20xx Sydney Olympic Games.
There are thousands of unique animals in Australia, and only 13 common and famous animals are selected in the book. While introducing animals, the author inserts some of his own views by means of narration and discussion.
Sixth, the structure of the article.
The text *** 10 paragraph can be divided into four parts.
The first paragraph is the first part. The Sydney Olympic Games introduced the main body of things-the echidna, and emphasized that "only Australia has its footprint on the whole earth", which aroused people's interest in reading from the beginning and highlighted its rarity and rarity.
The second part (2 ~ 5) introduces the appearance of the echidna and its excavation characteristics. The author uses the method of column number and comparison to illustrate the following characteristics of the echidna: its body is very small, full of thorns like a hedgehog, and it is very good at digging and fast. "Even modern tools, even machines, may not catch up with it." This paragraph is about the magic of the echidna from the outside.
The third part (6 ~ 9) describes the life habits of the echidna: mainly eating ants, active in the daytime, dormant in winter, able to swim, rough stomach epidermis, and so on.
The fourth part (10) focuses on the breeding of echidna. This passage can best reflect the rarity of the echidna: it is oviparous and belongs to mammals (there are only two known oviparous mammals in the world: echidna and platypus); Although there are cysts, they only appear during the breeding period; Dig a "nursing nest" when you are pregnant, and have a unique feeding method, and so on.
Seven, writing characteristics
1. Grasp the characteristics of the explained things and highlight their rarity.
2. Clear organization and detailed introduction from several different angles.
3. The proper use of metaphors, figures, analogies and other explanatory methods makes readers have a clearer understanding of this strange little animal.
4. The language is concise and vivid
Eight, after-school problem solving
(1) 1. The main characteristics of the echidna are: small size, full of thorns; Have sharp claws and are good at digging; Mainly eat ants and sleep in winter; Laying eggs, breastfeeding, temporary bags under the eyes, etc.
2. The text can be divided into four parts. The subheadings of each part are: the first part (paragraph 1), the mascot of the Sydney Olympic Games; The second part (paragraphs 2-5) is an expert at digging holes with thorns all over; The third part (paragraphs 6-9), human friends who eat ants; The fourth part (section 10) is a peculiar breeding mode. Subtitles don't have to be the same, as long as they can summarize each part more accurately. )
(2) This topic is an open topic, mainly to arouse students' attention to animal protection, and practice briefly explaining one thing at the same time.

How do verbs (short for verb) judge the following sentences?
1. The shape of the echidna is similar to that of a hedgehog, with a length of 300 ~ 450mm and a width of less than 70mm. ( )
2. (echidna) Curls its body like a hedgehog, like a ball ...
3. Its food sources are ants and earthworms in Australian grasslands, hills, deserts and mountains. ( )
It is not as fast as hedgehogs and rabbits, and even modern tools and even machines may not be able to catch up with it. ( )
Read the following article and then answer the questions.
(1) Of course, digging holes is not the main duty of the echidna. Its food source is ants and earthworms in Australian grasslands, hills, deserts and mountains, including termites that Australians hate. Many houses in Australia are destroyed by termites every year, and farmers like cute little echidna, which naturally includes this factor.
The echidna has a long tubular mouth, and its nostrils open at the top of its beak. The tongue is also an important weapon of the echidna. It can stick out its mouth for more than a foot. A thick mucus is secreted on the tip of the tongue, which is used to stick the ant's stomach. It is estimated that it can eat tens of thousands of ants and termites a day.
The echidna usually moves during the day, and goes out to look for food every day 18 hours, and detects invertebrates such as ants and earthworms with its nose. Its nose and mouth can detect and feel very subtle bioelectric signals and quickly capture food. At night, it sleeps in bushes, hollow logs, crevices in stones, and even caves of rabbits and wombats, because these animals are helpless. Of course, it doesn't compete for other people's food. It hibernates in winter, even in the mountains for 28 weeks. During this period, its movements and reactions are very slow. In fact, winter in Australia is not cold, and there is no ice and snow. The temperature in parts of North China and Central China is still above zero 15 degrees Celsius. In the first few days of spring, the echidna that comes out for food moves slowly and comes out more often. The echidna moves slowly, such as rolling, but strangely, it can swim and float on the water like a hairball, which is very funny.
August to 10 is the season when the echidna attacks large ant nests. There are many fat queens with wings in the nest. These queens have prepared enough fat and nutrients to fly out of their nests and build new homes. At this time, the echidna uses its long nose and mouth () to attack the nest, () to show its tongue full of mucus, () to hold food, and () to enter the mouth. When it sticks to the queen, it will also bring in a lot of dirty things, but it doesn't matter. The echidna eats a lot of soil every day, which not only helps digestion, but also contains rare elements. The echidna has a rough stomach epidermis, which is very different from other mammals. After eating such a sumptuous dinner, the little echidna grew very fast, and suddenly became much bigger in spring and summer.
1. Fill the brackets in the fourth paragraph of the selected article with appropriate verbs.
2. What is the important reason why the echidna becomes a friend of Australians?
3. How much do you know about the life habits of the echidna from the selected articles?
4. What are the characteristics of the bold words in the second paragraph in the selected text in the language described in this article?
5. What other rare animals do you know? Please briefly introduce their growing environment, habits and present situation.
(2) The unique skills of Arctic insects
(1) In the Arctic region, due to the harsh environment and climate, the species of insects are much less, only a few thousand, mainly including flies, mosquitoes, mites, midges and spiders. Among them, flies and mosquitoes account for the most, accounting for 60% ~ 70% of the total number of insects.
(2) Large animals and birds can rely on long hair to resist the cold, but insects can only be naked forever. So, how do they survive the severe winter in the Arctic? In fact, most insects are frozen for about nine months in a year. They exist in soil, mud or swamp, and freeze with the surrounding materials. We know that ice is a crystal, but if an insect's body crystallizes, it may destroy its blood vessels and its body. In order to prevent this, arctic insects have evolved a stunt, that is, they can automatically minimize the moisture in cells, thus effectively avoiding crystallization. There is also a cow fly in the Arctic, which is a terrible parasitic insect. After hatching, it enters the reindeer and swims all over the body along the blood vessels. When I grow up, I go back to the reindeer's spine and open a skylight to breathe fresh air until I grow up and drill out the reindeer's body for a new round of reproduction. Arguably, the reindeer is delicate and delicious, and has no defensive ability. They are the best delicacies, but cows and flies never attack them. Because if cattle flies lay eggs on young reindeer, although it is much easier, it may lead to a sharp decline or even extinction of reindeer population. At that time, the flies themselves will be difficult to survive. Small cattle and flies, as early as hundreds of thousands of years ago, knew such a profound truth and had to arouse human thought. In addition, there are certain restrictions on the number of eggs laid by cattle flies in each herd of reindeer. They keep the number of eggs in a certain proportion and try to avoid laying too many eggs on the same reindeer. If you lay too many eggs on a herd of reindeer, it may lead to the extinction of the whole herd. If the same reindeer lays too many eggs, it may die or be eaten by natural enemies because of its weakness. In this way, their descendants will perish together.
Insects living in the Arctic face another special difficulty. After all, the Arctic is vast and sparsely populated, and even animals are scarce. How do insects find their targets? According to the research of biologists, mosquitoes have a very advanced infrared detector, which can accurately detect the infrared rays emitted by people and animals at a long distance, so as to track the tracks and attack them in groups. The infrared detectors used by human beings have only been developed in recent decades, which are not only bulky and bulky, but also display blurred images. Compared with small mosquitoes, humans have fallen behind for centuries. As for those moths and butterflies, how they fall in love from a distance makes biologists puzzled.
(4) in the arctic land for field work, the most terrible is blackfly. Their sense of smell is very sensitive, and they can smell people from a distance. They immediately flew in droves and buzzed like bombers, which made people jumpy. Because even wearing thick clothes is useless. Their steel-needle-like mouths can bite through the old skin on their feet, then go deep into your skin and suck your blood. At the same time, also spit out a kind of venom. It is unpleasant to feel blisters, swelling and pain, or even ulceration at the bitten place.
In the Arctic, the world of insects is so wonderful.

(or: insects can't find food to live on) (2) automatically reduce the water in cells to avoid crystallization; Use infrared detectors or a keen sense of smell to find the source of food. 2.( 1) Cattle and flies do not lay eggs on young reindeer, because doing so may lead to a sharp decline or even extinction of reindeer herds, and it will be difficult for cattle and flies to survive then. (2) In order to survive better, human beings must protect the environment on which they live. 3. For example, the first paragraph "mainly includes flies, mosquitoes, mites, midges, spiders, etc." 4. Survival of the fittest (or: only by adapting to changes in the environment or practicing stunts to adapt to changes can we survive. )
