给你英文的‘script":Script:Let"s say you want to become pope, head of the Catholic Church and shepherd to over 1 billion faithful.What requirements must you have for this lofty position:1) Be a catholic and2) Be a man.Which seems a little thin… and, while it"s technically possible for a regular Sunday Catholic to become pope, the last time this happened was essentially never because becoming pope isn"t like becoming president, you can"t just run for office. Selecting the pope is an inside job and the men who do it are the cardinals, and while in theory they can select any catholic man to become pope, in practice they prefer to elevate one of their own.The last time a non-cardinal become pope was more than 600 years ago. So, while it isn"t an official requirement, it"s an unofficial, official requirement.Thus in order to be pope you"ll first need to be a cardinal and to do that you"ll need to start climbing the catholic corporate ladder.*Step 1: Become A Priest.Unlike some churches where you can fill out a form online and -- poof -- ordained. The Catholic Church treats becoming a priest as a real, you-need-training profession. So you"re going to require a lot of education: usually a college degree in Catholic Philosophy and then a masters in divinity.In addition to your educational qualifications, you must also be:A manUnmarried,Willing to remain celibate forever.�6�9If you meet these requirements, and have been working with the church, then you can be officially ordained as a priest. Which basically means you get to run a Catholic Church, or work with another priest who does.But, you want onward and to do that you need to take the job of the man who just made you a priest.Step 2: Become A BishopBishops are a much more select group: while there are about 400,000 catholic priests world wide, there are only about 5,000 bishops.While priests get churches, bishops get cathedrals, from which they oversee a number of local churches.To advance your career you must wait for a bishop in your area to be forced into retirement at age 75 or die sooner than that -- freeing up space for you.But you can"t just apply, because there"s already a secret list of potential bishops that"s updated every three years based on who the current bishops in your area think would make a good replacement for one of their own.To be on that list, in addition to the obvious requirement of being a pious person, you should also:Be least 35 years oldHave been priest for at least five yearsHave a doctorate in theology (or equivalent)Assuming you"re all these things, your name may, or may not be on the secret list. The local bishops then give that list to the pope"s ambassador for your country, known as the Apostolic Nuncio.The Nuncio picks three priests from the list, does in-depth research on them, conducts interviews and selects the one he thinks is best.But it"s not over, because the Nuncio sends his report to Vatican City and the congress of bishops who work there reviewing potential appointments from around the world.If the congress of bishops doesn"t like any of the three candidates, they can tell the Nuncio to start over: returning to the list, picking another three candidates -- doing more research, more interviews and sending off the results.When the congress of bishops is happy with one of the Nuncio"s candidates that name is given to the pope, who can reject the candidate and start the whole process over.It shouldn"t be a surprise that from a vacancy to a bishop"s replacement can take months and, on occasion, years.But assuming that a bishop in your area retired (or died) at the right time and you were on the secret list of good priestsand the Nuncio picked you and you made it through his interview and the congress of bishops approved you and the pope didn"t veto you -- poof now you"re now a bishop.But you"re still not on top. The penultimate promotion is...Step 3: Become A Cardinal.Despite the fancy name and snazzy red outfits to match cardinals are not the bosses of bishops, they are bishops, just with an additional title and additional responsibilities -- the most notable of which is electing the new pope.�6�0The only way to become a cardinal is to get to current pope to appoint you as one -- and of the 5,000 bishops, only about 200 are ever cardinals.But let"s say your ambition doesn"t go unnoticed by the pope and he makes you a cardinal -- now it"s time to play the waiting game for his death or retirement -- and with popes death is vastly more likely.When either happens the cardinals under the age of 80 are brought to Vatican City where they are isolated from the outside world -- presumably by taking away their cell phones and tablets and carrier pigeons. Once sequestered, the election of a new pope can begin.These elections are never exactly the same because the ex-pope leaves instructions on how he wants his replacement to be picked, but in general it works like this: four times a day the cardinals go to the Sistine Chapel to vote -- to become pope one of them must get a 2/3rds majority.There"s a big dose of mustn"t-be-too-hasty here as the cardinals don"t just raise their hands, or use a modern preferential voting system, but instead write down one name on a piece of paper stand before the alter and say a long latin phrase, before officially casting the ballot.Once all the cardinals have done this, the votes are counted and then burned.This why TV news stations covering the election of the pope use super-modern-hd-livestreaming cameras to look at a chimney. If the smoke is black, no new pope.The high victory threshold, and tediously slow voting process, is why it takes so long to elect a new pope. It"s usually at least two weeks of voting four times a day six days a week (with one day a week for prayer) but the record length is three years.Assuming you, eventually, win the support of your fellow cardinals, you have one final thing to do before becoming pope: pick yourself a new name.There is no formal rule, you can name yourself anything you like but it"s tradition to take the name of a previous pope.Upon your acceptance of the job, the final ballots are burned clean to make the smoke white and announce to the world that a new pope has been selected.So that"s the career path: be born into the right half of the population, become one of a billion catholics, then one of 400,000 priests, then one of 5,000 bishops, then one of 200 cardinals, wait for the current pope to die or retire, and convince 2/3rds of your fellow cardinals to select you as the one, the only pope.

没有competitice这个单词，类似的单词是competitive。typical和competitive区别是：意思不同。如下所示：typical意思是“典型的，有代表性的；一贯的，平常的”。competitive意思是“竞争的；好竞争的，好胜的；有竞争力的”。typical用法：typical后面可接介词of，固定搭配为typical of sb/sth，意为“有代表性的人／典型的事情”。如：This pattern of woods and fields is typical of the English landscape.这是具有典型英格兰风景特征的森林与田野。competitive用法：固定搭配为competitive (with sb/sth)，意为（与…）一样好的；（比…）更好的；有竞争力的。如：We need to work harder to remain competitive with other companies.我们必须更加努力工作以保持对其他公司具有竞争力。

friendship 是友谊companionship 指的是有人陪伴你

television[英][ˈtelɪvɪʒn][美][ˈtɛləˌvɪʒən]n.电视节目; 电视，电视机; 电视业; 网络电视网; 电视,电视机; 电视剧; 复数：televisions

翻译为“成为网络名人”。celebrity 意思是“名人，名声”。network 作为名词，意思是“广播网，电视网；网络；联络网”。

书面语与口语的区别，另外作为口语burn的含义要广的多

celebrate和congratulate均有“庆祝、祝贺”的意思,两者都是动词.区别在于： 1、celebrate：通常指庆祝有意义的日子或事件,常常伴有盛大的庆典仪式,多指庆祝节日. 例如：How do people celebrate new year in your country? 你们国家的人怎样庆贺新年? The Society is celebrating its tenth anniversary this year. 这个协会今年将举办成立10周年庆典. 2、congratulate：指对他人祝贺为目的,希望他人幸福或走运或表达对某人的表扬.有以下三种用法： （1）congratulate sb.for sth.为某事向某人表扬、庆贺 I really must congratulate the organizers for a well run and enjoyable event. 活动安排得有条不紊,充满乐趣,我必须要称赞一下组织者. （2）congratulate sb.on...就…向某人表示祝贺 Congratulate him on following up your leads. 如果他听从你的建议,就向他表示祝贺. （3）congratulate that+从句 We congratulate that he is accepted to join the Party. 我们祝贺他被接受入党. 因此celebrate常用于庆祝某事,而congratulate则多用于祝贺某人.根据题意,his daughter"s being admitted to Qing Hua University 是一件值得庆贺的事情,因此用celebrate.若用congratulate,则可写成：congratulate on him that his daughter has admitted to Qing Hua Universit
