次の英文の日本語訳がわかりません。誰か教えてください。 (1)There are, however, two problems with its industrial use. (2)First, the fusion of deuterium and helium-3 is very difficult to start and sustain, requiring roughly more energy than the fusion of deuterium and tritium. (3)Second, there are no plentiful stocks of helium-3 on earth. (4)Although the isotope is found naturally as a trace component in stocks of natural gas and also as a decay product of tritium, there is not enough helium-3 on our planet to support commercial power generation through fusion. (5)Because the moon has been exposed for billions of years to the solar wind, which consists largely of ionized hydrogen and ionized helium, helium-3 is available in the dust of the lunar surface.

(1) しかし、その工業的利用には2つの問題が、あります。 (2) 第1には、ジュウテリウム(重水素)とヘリウム-3の融合はとても始めにくいし、継続しにくいのです、また、ジュウテリウムとトリチウム(三重水素)の融合より大まかに言っても多くのエネルギーを必要とします。 (3) 第2には、地球上には、ヘリウム-3の豊富な資源がありません。 (4) 同位体が、天然ガスの資源の微量成分として、また、トリチウムの減衰成分として自然に見つかりますが、核融合によって商業発電を維持してゆくのに十分なヘリウム-3は、地球にはありません。 (5) 月は、主として、イオン化された水素とイオン化されたヘリウムからなる、太陽風に、何十億年もの間さらされているので、ヘリウム-3は月面のちりの中から手に入ります。

    以下の英文の日本語訳で困っています。誰か教えてください。 (1)Of the 12 men who have walked on the moon, Harrison Schmitt, is the only one with scientific training in geology. (2)Schmitt's work on the Moon in 1972 ranks as one of the most exciting and productive episodes in the history of exploration. (3)His new book, Return to the Moon, is structured as a legal document, in which Schmitt argues for returning to the moon to mine the isotope helium-3. (4)He claims that because fossil fuels are limited in supply and because their extraction and use harm the environment, our world requires new sources of energy. (5)The ultimate solution, he suggests, is the generation of power by nuclear fusion-not of deuterium and tritium, as is usually proposed, but of deuterium and helium-3.

    A good farmer is always one of the most intelligent and best educated men in our society. We have been inclined in our wild industrial development, to forget that agriculture is the base of our whole economy and that in the economic structure of the nation it is always the cornerstone. It has always been so throughout history and it will continue to be so until there are no more men on this earth. We are apt to forget that that the man who owns land and cherishes it and works it well is the source of our stability as a nation, not only in the economic but the social sense as well. できるだけ詳しく教えていただけると嬉しいです。 よろしくお願い致します🙏

    次の英文を日本語訳にしたいのですが、うまく訳せません。だれか教えてください。お願いします。 (1)Even there, however, helium-3 is present only in concentrations between 10 and 20 parts per billion. (2)We must mine hundreds of millions of tons of lunar soil to extract a ton of helium-3. (3)Schmitt has looked at this problem in some detail, and he outlines a plan for mining helium-3 on the moon to feed a commercial industry for generating power here on earth. (4)After a brief introduction and a short discussion of the data obtained from the Apollo Moon missions, Schmitt considers the future of energy production on earth, concluding that all of the various proposed alternatives to fossil fuels have problems. (5)However, he maintains that mining the moon for helium-3 is a viable solution to our energy problems. 問題は以上です。特に、(4)がめちゃくちゃ長くて、どう訳したらいいかさっぱりです。

    The forests of the earth are home to most of the world’s species, but living things there are in crisis today. Many places on the earth need to be protected, but how can we protect all of them at the same time? In 1988, a British biologist named Norman Mayers conceived of the idea of “hot spots” to identify particular places on the earth that need to be protected urgently. A hot spot is determined by the level of danger faced by a species in a particular region. There are hot spots on land as well as in coral reefs, but in the case of land hot spots, the number of native plants in a region is one factor that determines whether of not it is a hot spot.

    And should we defeat every enemy, and should we double our wealth and conquer the stars, and still be unequal to this issue, then we will have failed as a people and as a nation. For, with a country as with a person, "what is a man profited if he shall gain the whole world, and lose his own soul?" There is no Negro problem. There is no Southern problem. There is no Northern problem. There is only an American problem.This was the first nation in the history of the world to be founded with a purpose. The great phrases of that purpose still sound in every American heart, North and South: "All men are created equal." "Government by consent of the governed." "Give me liberty or give me death." And those are not just clever words, and those are not just empty theories. In their name Americans have fought and died for two centuries and tonight around the world they stand there as guardians of our liberty risking their lives. Those words are promised to every citizen that he shall share in the dignity of man. This dignity cannot be found in a man's possessions. It cannot be found in his power or in his position. It really rests on his right to be treated as a man equal in opportunity to all others. It says that he shall share in freedom. He shall choose his leaders, educate his children, provide for his family according to his ability and his merits as a human being. To apply any other test, to deny a man his hopes because of his color or race or his religion or the place of his birth is not only to do injustice, it is to deny Americans and to dishonor the dead who gave their lives for American freedom. どなたかお願いします。

    part1の続きです。 It is claimed that many British companier are losing business through a lack of language skills. Telephone operators often do not understand enough to put through overseas calls,and in a league of European companies with executives who are able to negotiate in a foreign language,Britain is second from bottom. Because of poor language skills at home,employers in Britain are turning increasingly to nationals of other countries when recruiting staff,especially in areas such as hotels,commerce and international transport. Nor is there much good news from British schools,where statistics show that languages are not given as much priarity as in other parts of Europe.

    結構長い英文なのですが、英語が得意な方翻訳お願いします。それか各小節の概要でも教えて頂けるとありがたいです。 The ancient city of Peshawar is located in Pakistan, close to the site of the earliest Buddhist sculptures. Sheep are abundant in that area. Medieval wooden homes line the dark streets, and here and there smoke rises from small restaurants nestled among the homes. All the restaurants serve sheep meat, or mutton. The meat is served grilled on skewers or as small steaks. The most delicious fragrance of all comes from kabobs. Kabob, also called kebab, means "grilled meat" in Arabic. The most common meat comes from sheep. The cheapest and best kabobs are found in small restaurants where the meat is grilled over charcoal. Chunks of meat are placccl on skewers and grilled over a charcoal fire. That's it. If the cook is skillful, the meat is moist, and melts in your mouth. Large restaurants will season the meat and cook it with onions, however, the authentic kabob is not even seasoned with salt. The quality of the meat determines the flavor, so small authentic restaurants are the best place for kabob. The word shish kabob comes from the Turkish language, and is understood just about everywhere. Sheeps meat is considered a great delicacy just about everywhere in the Middle East and Central Asia. The entire animal is eaten, including its innards stand alongside stalls selling mutton. There are corners where dozens of sheep's heads will be displayed for sale. The brains are considered the tastiest part of the animal, and area eaten boiled with a squirt of fresh lemon. In various regions throughout the Middle East and Central Asia, there is an annual rite in which sheep are sacrificed, and the meat is distributed to relatives and neighbors. It is said that in Pakistan, the finest hospitality is shown to company by killing a sheep in the morning and serving its brain in the evening. There is probably no meat as universally populer mutton. It cuts across religions and cultures. For example, Japanese research institute found that the traditionally picky Parisians consumed more sheep and duck than any other types of meat. A guest at a Parisian family dinner is likely to find a mouth-watering plate of roast leg of lanb on the bone in the center of the table. There are Japanese who claim to be put off by the smell of roast lamb, but that is probably because they have never smelled really fresh roast lamb. There are sometimes surprises in sheep cusine. There are many restaurants in Sofia, Bulgaria, specializing in sheep cusine, but if you cannnot read the Bulgarian menu and simply order "the specialty of the house," you are likely to end up with roast sheep's head. This is considered a Bulgarian delicacy, and the tastiest part of the sheep. The British English expression, "mutton dressed as lamb," goes back a long way. Mutton is meat from mature sheep, while lamb is meat from a young sheep. The phrase indicates an older woman who tries to make herself look young. The old English phrase "eat one's mutton with..." means "to dine with..." Sheep are not just for meat. In the Middle East, Europe, and elsewhere, sheep are free-range domestic animals who are loved for their cute cuddliness.
