these are not comfortable questions, but, by god, they need to be asked.”he added, “at the moment these costs do not appear in anyones books. yet they are real, they are incurred (遭受) now and in a relatively short time, the damage being caused may be beyond remedy(补救). ”he said the world was “running up the biggest global credit card debt in history, but with little or no thought for how the bill will ever be paid”.flanked by (两侧有) the prime minister and business and community leaders at st james palace, the prince said his new “accounting for sustainability (可持续性)” project would give consumers the power to choose products that caused less damage to the planet.duchy originals, the princes food company, is taking steps to quantify how much carbon dioxide and other greenhouse gas is emitted in growing, processing and distributing its products.the changes to the princes travel arrangements announced yesterday are part of a wider review of the carbon footprint associated with activities at all three of his residences clarence house in london, highgrove and birkhall on the balmoral estate, as well as the activities of his 21 personal and 105 full-time staff.measures incl ude a review of electricity use, commuter(通勤者) and other staff travel and are intended to identify further reductions in carbon dioxide emissions. the review will report in june, when clarence house will announce annual targets to reduce carbon emissions.6. one of the moves prince charles will take to reduce the royal impact on the environment is .a. taking private jets that are not carbon-heavyb. taking helicopters instead of private jetsc. taking trains instead of scheduled flightsd. taking scheduled flights instead of helicopters7. how does prince charles feel about business leaders in terms of environmental protection?a. dissatisfied. b. disappointed. c. doubtful. d. impatient.8. duchy originals will _in response to prince charles-calls.a. make as much green food as possible b. cut down on its electricity usec. figure out its greenhouse gas emission d. reduce its greenhouse gas emission9. the underlined phrase “the biggest global credit card debt” in the third paragraph probably refers to .a. the great amount of waste produced by industryb. the great damage caused for the environmentc. the great amount of debts of the royal familyd. the high cost of industry in the producing process10. what would be the best title of the passage?a. prince charles promises greener royal lifestyle b. better late than never c. prince charles and his concern for the environmentd. the royal family has a role to play in environment protection考试范文你叫李华，是一位生活在济南的中学生，五一节期间，应同学邀请，去乡村游玩。根据你的所见所闻，写一篇120词左右的英文日记，简要说明城市不足与农村的优势。today, my classmate invited me to his hometown, a beautiful village, for a holiday. this was the first time that i had gone to the countryside and i was glad to accept his invitation. when i got there, i was wide absorbed by the beautiful surroundings. the air was fresh; the sky was blue; and the grass was green. what impressed me most was the villagers enthusiasm.compared with the countryside, our city is too crowed. and there are too many cars and buses on the road. also the air pollution is a great problem we are facing, as it may cause us plenty of diseases. and im tired of living in such a place. how i wish i can live in such a beautiful mountain village one day! 选修8 unit 2 cloning答案. 单词拼写. 翻译句子1. tell your parents the tr uth, for they are bound to know all about it.2. the project raised a storm of objections and had a great impact on the villagers.3. though he was in favour of the plan, he didnt make straightforward replies.4. he has accumu lated a lot of teaching experience during the past 10 years.5. his assumption that human beings can clone animals was proved at last.单项填空1. 解析：选a。从just think hes a bit annoying可知，说话人表达的是并非真的讨厌他。not exactly 不完全的。2. 解析：选d。句意表示“只是偶尔去看电影”，因此用from time to time(偶尔)。at one time曾经;for a time一段时间;at a time每次。3. 解析：选d。句意为：尽管这对双胞胎看起来很像，他们在很多方面都
