Hetty Robinson learnt all about money when very young. As a child, she read the financial pages of the newspaper to her rich father. Her father died when Hetty was 30, and she inherited $1 million. When she herself died in 1916, she left almost $100 million to her two children.

    Hetty made her money on the New York stock(股票) exchange. She was a financial genius. She made money so easily that people called her the Witch of Wall Street. But although she was one of the richest women in the world, she counted every cent and spent as little as possible. She didn't own a house, because she didn't want to pay taxes. So she and her children lived in cheap hotels. She spent almost nothing on clothes, and always wore the same long black dress. She washed it herself, but to save soap she only washed the bottom of the dress, where it touched the ground. Other people had their own offices, but Hetty used a desk in the bank where she kept her money, because it didn't cost anything. She sat in the bank and ate her sandwiches while she bought and sold stocks and shares. If the bank complained, she just moved all her money to another bank.

    Hetty's family paid the price for her meanness. When she was 33 she married a millionaire, Edward Green, and they had two children. But Green lost all his money, so she left him. When her son, Ned, injured his knee, Hetty didn't want to pay for a doctor, so she took him to a free hospital for poor people. Unfortunately the doctor knew Hetty was rich and he asked for money. Hetty refused and took the boy away. His leg got worse and two years later doctors removed it.

    But eventually Ned got his revenge(报复). At the age of 81, Hetty had an argument with a shop assistant about the price of a bottle of milk. She became so angry that she had a heart attack and died. So Hetty's meanness finally killed her. Ned inherited half his mother's fortune, and he spent it all on parties, holidays and expensive jewellery.

    We could say that any animal that knows how to find food, avoid being eaten, and raise babies is pretty smart. But can animals learn and remember or can they solve problems?

Many animals have good memories for where food is — a useful skim Scrub jays (灌丛鸦) may be the champions. In one experiment, scientists put them in pre-made holes. After the jays had hidden some food, they were taken out. Scientists mapped where the food was hidd6n and then remove ii, which meant the jays couldn't find the holes by smell. But when the jays came back again, they went right to the hiding they had used. In the wild, they remember where thousands of holes arc. Could you do that?

    Another important smart skill is being able to spot shapes and generalize. This kind of test work best with animals that see well and are interested in pictures. Call in the pigeons(鸽子)! In this test, pigeons had to learn to pick out photos with trees in them, and to ignore photos that didn't include any trees. Once they had learned the rules, they were very adept at it.

    Scientists have to be careful when they test animals for smarts, and the person giving the test has to know the animal really well, in one experiment, a few bananas were hung out of reach over a p on the ground. Monkeys figured out right away how to get the bananas: pick up a stick and knocked down. But clever elephants kept failing this test. Finally scientists figure out why. An elephant's trunk work as both its hand and its nose. When it got the stick, it couldn't smell the bananas. When the elephants were given a couple of boxes instead, they quickly use them to make a step and got the bananas.

    As we're learning, the world is full of smart animals, each thinking in its own special way.

    Tang Dynasty poets sang for about three centuries in different tones. There were many famous poets living in the Tang period such as Li Bai, Du Fu, Bai Juyi and Li Shangyin. Poems of the Tang Dynasty edited in the Qing Dynasty is a collection of more than 48,900 poem that were written by over 2,200 poets. But it didn't cover all the poems of the Tang Dynasty.

    During the Tang Dynasty, poems were recited when lovers walked under the moonlight. Poems were also recited when soldiers fought on the battlefield. People recited them in the open air or at temple fairs.

    Tang Dynasty poets wrote poems to win fame and also to develop their temperament(性情). They poured out deep feelings for their friends and criticized in injustice in the world through poems.

    In the Tang Dynasty scholars had to be poets. Their readers were not only people of high social position but also common people. Poets recited poems, women singers sang poems and other ranks of people, including old women and children, read Tang poems. This atmosphere affected foreigners who visited the country at that time. As a result, Tang poetry was introduced to some adjacent countries, like Japan and Vietnam.

    Tang poetry is a most brilliant page in the history of ancient Chinese literature. It's a miracle in the cultural history of mankind. The Tang Dynasty was a powerful empire with a vast territory. It inherited(继承)Chinese civilization that went back to ancient times, was combined with the best of other cultures and adopted the benefits of other nations in the world. Tang poetry wasn't the only spiritual wealth created by the Tang Dynasty people. Philosophy and religion, handwriting and painting and music and dance all gained new peaks of development. Tang poetry, however, was the jewel in the crown and its greatest achievement.

    Nature Nurtures Farm plans to organize some charity activities in this summer. It hopes to teach young people about charity. The farm wants to get about 30,000 dollars through these activities.

    As our closest neighbor in space, the moon has been the subject of popular myths, songs and poems since ancient times. And it has no less fascinated scientists. But even after centuries of research many questions remain to be answered about Earth's only satellite. Perhaps the Chang'e-4 lunar probe will be able to reveal more of its secrets.

    On Dec 8, the probe lifted off from Xichang Satellite Launch Center in Sichuan Province. It is the first probe to the far side of moon.

    The Earth's gravity slows the moon's rotation, matching it to the speed of its orbit. Thus, the far side of the moon is always dark and has never been seen. It's this sense of the unknown that makes the far side of the moon such an interesting place for scientific and space exploration.

Long exposed to solar winds, the far side may have the special soil and minerals in its upper mantle(地幔).For this reason, Chang'e-4 will study the effect of solar winds on the lunar surface and any minerals found beneath the spacecraft.

    Chang'e-4 is also carrying flower seeds and potato and silkworm eggs to see whether life is possible on the moon. If it is, then the moon will become a more likely destination for space travel in the future. However, due to communication problems, exploration of the dark side will not be easy.

    As the far side is blocked off from us, radio noise coming off Earth is also blocked. This is why China launched the relay satellite Queqiao in May—so that communication between Earth and the probe could go ahead. Power supply will also be a challenge to the mission.

    Chang'e-4 gets energy from the sun through its solar panels. However, a lunar day has the length of 28 Earth days. This means that the probe will need to orbit the moon for over 20 days to be in a position to be able to land in moon daylight and so use its solar panels.

    According to Xinhua, if everything goes well, the satellite will land on the far side on Jan 2.

    The New York Times described the journey as “groundbreaking”, and wrote that it will “give clues to the history and development of the moon”.

Uggs(雪地靴) are certainly ugly, or at least inelegant. The shapeless boots, pulled on in a hurry, can make anyone look like a slob(懒惰的人), which has made them the target of disrespect. It hasn't been hard to find someone strongly condemning them." Ugg boot s are no sexy," The Independent declared in 2003," unless you' re Mrs. Bigfoot on a lo ne mission across Antarctic to find Mr. Bigfoot. When wearing the boots, a writer of The Gloss complained," There's nothing to indicate that you don't have square, horrible shoeboxes in place of human feet." In 2015, one coffee shop on Brick Lane in east London ever banned ugg- wearers.

And yet, over the years, plenty of strange and unattractive shoes have met with the approval of the fashion establishment. The problem with ugg' s wasn't that they were ugly; it's that they were common.

But a funny thing happened on the way to fashion's tomb: the universal ugg has not gone anywhere. Uggs have quietly stayed here since their best time. Once you start paying attention, you' ll be shocked to discover how many people are still wearing them. They are worn by mothers in town and in the country, by teenagers on Saturday shopping trip and by people in fashion.

Perhaps the secret of uggs's unstoppable success is that, if there is a dividing line between public appeal and private style, it might be a pair of cozy boots. They are certainly comfortable, soft and warm, as if your feet were in the hugging of someone who really loves you. At$150a pair, they are neither cheap nor entirely out of range. They are casual and indulgent(纵容的).

Somehow uggs, the boots that so many people hate, have managed to challenge the cruel logic of the fashion cycle and carry on whether you approve of them or not.
