Metal and Iron in Ancient Times
- Metal, especially iron, played a crucial role in ancient times. It was used for weapons, weights, coins, and monuments.
- Iron was obtained from iron ore, which is a mixture of rock and metal. It was smelted by crushing the ore and heating it to a high temperature using charcoal.
- Once smelted, iron could be shaped into various objects like swords, weights, and seals. Heating iron with charcoal resulted in the production of steel, a harder metal. Steel stamps called punches were used to stamp royal symbols on silver coins.

お願いします。 Metal,especially iron,was very valuable in ancient times.Rulers used it for weapons,weights,coin manufacturing,and monuments.Iron usually starts as iron ore,a mixture of rock and metal.The iron is smelted by crushing the ore and heating it to a very high temperature.Only charcoal burned hot enough to smelt iron.India's jungles have both iron ore and lots of trees to make charcoal. Once a blacksmith smelted the iron,he hammered it into sheets or bars that could later be shaped into swords,weights,or seals.When heating iron with charcoal,carbon fuses with the iron and makes an even harder metal called steel.Because steel is so hard,it could be used to stamp other,softer metals like gold and silver.The Mauryan government soon established mints where steel stamps called punches stamped royal symbols on pieces of silver,turning them into coins. So many of the problems that the people of South Asia tried to solve－how to have healthy,happy life,where we are in the universe,how to keep track of time and money－are the same problems that we try to solve today.And,despite our huge technological advantages,many of their answers continue to be help us thousands of years later.Just think what the doctors who developed Ayurveda and brilliants scientists like Aryabhate might have discovered if they'd had computers!

金属、特に鉄は、古代に非常に貴重でした。 統治者は、武器、重り、コイン鋳造、記念碑のためにそれを使いました。 鉄は、通常、岩石と金属の混合物である鉄鉱石として始まります。 鉱石を圧砕して、それを非常に高い温度まで加熱することによって、鉄は溶解されます。 木炭だけが、鉄を溶解するのに十分熱く燃えました。 インドのジャングルには、鉄鉱石と木炭を作るためのたくさんの木があります。 ひとたび鍛冶屋が鉄を溶かすと、彼は、それを鉄板や鉄棒の形にハンマーで整えました、そして、その鉄板や鉄棒は、後に、剣、重り、印鑑に形を整えることができました。 木炭で鉄を熱すると、炭素は鉄と融合して、鋼と呼ばれるさらにより硬い金属を作ります。鋼はとても硬いので、それは金や銀のような他のより柔らかい金属に印を押すのに用いることができました。 パンチと呼ばれる鋼のスタンプが銀の小片に国王のシンボルを押印し、それらをコインに変える、貨幣鋳造所を、マウリヤ朝の政府はすぐに設立しました。 南アジアの人々が解決しようとしたとても多くの問題 ― 健康で幸せな生活を送る方法、我々が宇宙のどこにいるのか、時間やお金の経過を追う方法 ― は、我々が今日解決しようとしているのと同じ問題です。そして、我々の巨大な技術的有利さにもかかわらず、彼らの答えの多くは、数千年後の我々を助け続けます。 彼らがコンピュータを持っていたならば、アーユルベーダを開発した医者たちやアーリヤバーターのような素晴らしい頭脳の科学者が何を発見したか考えてみてください！

至急こちらをお願いします。続き Does that mean that there were no women potters in later times? Probably not.In many regions of South Asia,even though men may throw pottery using the wheel,the women and young girls do most of the clay preparation and fime decoration work. Not every community lived near riverbed clay deposits,of course,so not every village had its own potter.But they may have had some other precious resource.Young people who lived near the sea,for example,became skilled divers and shell workers.Shell was used to make small tools and ornaments,especially bangles. People who lived in the Baluchistan Mountains to the west or the Aravalli hills to the east of Indus Valley learned how to work the copper in their soil.At first they collected bits of copper that were already in metal form and pounded them into beads or small pins and knives.They also developed techniques for getting copper from copper ore.Metal workers used wood charcoal to make very hot fires that could melt the metal out of the rock.To make the charcoal,people had to cut down forests.Over thousands of years,the copper-producing areas became deforested. Like shell bangles,stone beads were very common in South Asia,where they were symbols of wealth and power.The earliest bead makers drilled stone beads of soft limestone and soapstone in the highlands of Baluchistan and the deserts of Rajasthan.There were also deposits of chert,a hard stone that is easy to split into sharp-edged tonls,and jasper,a kind of quartz,suitable for making drill bits.Later bead makers shaped and drilled other types of stones,such as green serpentine from Baluchistan and blue lapis lazuli from Afghanistan.

以下の文章がものすごく難しくて、長いしどう訳せばいいかわかりません。 だれか教えてください。お願いします。 (1)After spending a period of time abroad, you may have to prepare yourself for a period of re-adjustment when you return home. (2)Simply because, if you have had a full experience living and learning overseas, you are likely to have changed, so the place you return to may itself appear to have changed, as indeed it might have. (3)But as you try to settle back into your former routine, you may recognize that your overseas experience has changed some or many of your ways of doing things, even what it means to “be yourself”. (4)But this intellectual and personal growth means that you can expect a period of difficulty in adjusting to the new environment at home.

日本語訳にしてください! Many governments now have or are considering laws to stop factories and towns from putting polluted water into streams. Factories are being required to treat their water before returning it to a public source. That is, if they put chemicals and other unwanted materials into water, they should be made to take them out again, so that the water can be by others. です、宜しくお願いします(；＿；)

お願いします (4) Egypt's empire stretched from Nubia to Syria. Tribute gifts flooded in from neighboring rulers who hoped to ally themselves with the powerful Egyptian king. Amenhotep IV must have watched a procession of riches being presented to his father. One ambassador after another laid gifts at his feet―exquisite jars from Crete, copper from Cyprus, jewels from Afghanistan, elephant tusks, giraffe skins, and ebony wood from Kush. Materialism was alive and well in Egypt. And everything had to be over the top. It wasn't enough to build a temple; the temple had to be COLOSSAL. A cloud of dust must have spread across Egypt from the dust raised by quarrymen and carvers, working the stone for all the buildings. (5) Traveling the Nile on the royal barge that was a floating palace, Amenhntep IV would have watched his father stop at town after town, performing rituals and paying tribute to the dozens of gods whose temples dotted the riverbank. Sailing against the current for the 400-mile trip from the northern capital of Memphis to the southern capital of Thebes would have taken three weeks without stops, but of course, there were always stops. Gratitude had to be expressed to the gods for Egypt's good fortune. That was the king's job. One day it would be Amenhotep IV's older brother's turn. (6) How different the two capital must have seemed to young Amenhotep IV. In Memphis he wouldn't gave been able to turn around without bumping into a scribe. Egyptians were compulsive record keepers. The archives bulged with their documents. A foreman couldn't hand out a loaf of bread to workman without someone writing it down. Governorr and overseers bustled through the streets of Memphis conducting Egypt's business, and the scribes recorded it all.

お願いします (1) Spartacus was born into a world of comfort and freedom. His father may even have been a nobleman. And yet Spartacus died a Roman slave. (2) Ancient writers give us only a sketchy outline of Spartacus's early years, but he was probably born in Thrace on the eastern fringe of Rome's huge empire. He served in the Roman army for a while but then deserted. Now instead of fighting to defend Rome, he became a rebel and a robber. (3) When the Romans captured him, they made him a slave and put him on the auction block. Whoever offered the most money would own him. Like all slaves in ancient Rome, Spartacus could be bought and sold as easily as a pottery bowl or a bundle of grain. If he got into trouble or tried to escape, he might be forced to wear a metal band around his neck. On one of these collars, now in a museum, are the words:“I have run away. Capture me. When you have returned me to my master...you will get a reward.”He might have had a brand on his face, made with a sizzling-hot iron. He could not own land or vote. He could not marry legally, and his children would be born into slavery. He could not choose his work; his master would make that decision. (4) Many foreign slaves, mostly prisoners of war, did the backbreaking work of building roads and aqueducts. Another unpleasant job was cleaning the public toilets and baths. But one of the worst places to work was in the silver mines of Spain. This was often the fate of slaves who had been convicted of crimes. The Greek historian Diodorus describes the lives of these men: Their bodies are worn down from working in the mine shafts both day and night. Many die because of the terrible treatment they suffer. They are given no rest or break from their work but are forced by the whiplashes of their overseers to endure the most dreadful hardships.... They often pray more for death than for life.

You may think that we make no drastic change to speech sounds we get through the ear. In truth, the brain controls the amount of information within reasonable limits. Two researchers recorded spontaneous conversation without the participants' knowledge. The tape recording was then cut up into recordings of individual words. These individual word recordings were played to people who were asked to identify what they heard. Surprisingly, played in isolation, only about half of the words were identifiable. Yet, when we are listening to continuous speech, we do not have the impression that we are guessing and filling in gaps. The speech sounds clear. If the tape recordings are cut up into larger and larger parts, then the comprehensibility of the speech increases. The normal Clarity of speech is an illusion. The brain imposes an interpretation upon the speech that it hears and constructs hypotheses about the general context and meaning, which enables the interpretation of much of the input. So, when two people claim that they heard a speaker say something slightly different, it may be that both are accurate. Each of them may have heard, in terms of a higher-level interpretation by the brain, a different sentence. The perception of speech may sometimes be a rather automatic process. We may not be aware that we are monitoring conversations in which we are not taking part. At a party you may be able to identify your own name in a conversation across the room despite apparent unawareness of the content of the rest of the conversation. In order to recognize that your name was spoken, the brain must have been monitoring the progress and speech pattern of the conversation which was taking place elsewhere, even though you did not notice yourself doing this. It appears that we can have the capacity to monitor more than one chain of speech at once, though it may not be possible for us to monitor both to the same degree, or for us to have full conscious awareness of the content of both. We are also able to attend selectively to one conversation, even if there are loud competing conversations in the background, by Extracting the relevant information from the complex signal of mixed speech. This is referred to as the cocktail party phenomenon.
