A seven day long holiday has flown away.Mourning my happy hours during the vacation,I've been looking forward to winter holidays.People around me seemed to have enjoyed the vacation,too.Then,is it fair that people have the same amount of holidays regardless of their occupations?Nevertheless,divergent views emerge on the matter in question.Some people are of the opinion that laborers should have the same length of holiday.They hold the view that people are born equal and should be treated equally.The same amount of leisure time may eliminate the unfairness among people who might be upset psychologically if otherwise.At first sight,it may seem to be an attractive idea,but it doesn't bear much analysis.To begin with,people do different kinds of jobs featuring different labor intensity and so the time needed to refresh their physical condition varies.For example,blue collar workers may work longer hours before they get tired physically,while white collar workers such as doctors and teachers are more mentally stressed.Unable to work continuously as long as those physical labor workers,white collars need more time to pull through the mental weariness than physical tiredness.All in all,people in different jobs assume different responsibilities and have different degrees of pressure.Secondly,different tasks and duties are required for different professions,resulting in the variety of holiday periods for people in different walks of life.Some employees cannot have their legal holidays and even have to work overtime,such as policemen,construction workers and people in the service line.Those professions just can't be interother wise the society will be in a mess.Even for some people in the same occupation,they cannot have the same holidays entitled to them due to many factors out of human control,such as special assignments,and health conditions etc,then not to say people in different fields.Suppose we,as teachers do,all have three months' holiday in a year.Then factories have to employ considerably more workers because some of them are enjoying happy holiday.That's obviously against the principles of doing business at lower cost and efficiency.If we have only three days off in a year,then all the people in our country will be working day after day.No one can squeeze time to visit those tourist resorts leisurely.It goes without saying that the tourist trade and catering industry thus cannot develop rapidly and healthily.有什么问题 请随时提问 有问必答 这篇作文希望对你 没有的话 我 在去英语作文大全里面帮您找找看 一定会有你喜欢的作文哈 不过希望 找和自己水平差不多的 你找的太好了 老师以为你英文很好了 到考试 时候 就没那么理想了 所以建议 不要和自己水平差太多的如何提高英语成绩大神们帮帮忙_百度知道

在，提高口语能力，每天背单词很重要，就想想它用英文怎么说，或者与其他人交谈，也容易懂。多听听力，如果觉得没兴趣的话可以听一些简单的英文儿歌，里面单词比较简单，有兴趣的话可以看看英文原声的电影，不要死背，起床之后可以晨读。口语也很重要刚起步应该打好基础，刚开始学英语时学习的单词都是很日常，中英文字幕都有的那种，简单的。生活里看到一样东西
1.听力： 听力部分是在考试里面最容易拿分数的部分。总分20分里面，如果听力水平较好，拿16-18分不成问题。所谓的水平好，我觉得只要能听懂voa stand english，应付六级就足够了。作为我个人，我没系统听过历年考试的题目，但是考试估分，听力都是16-18分。 最开始的时候，我连听voa special english都很困难。我的方法是：一个sp要听4-5次，把里面不懂的英语单词的发音，含义全部搞清楚，然后每天坚持2个小时的听力训练，狂攻sp。如果没事，就拿一个MP3吊耳朵，让 自己慢慢习惯英语语境。2个月后，我听了一盘四级英语考试磁带，发现自己原来根本听不明白的东西变的简单了。 现在，你已经具备了一定的听力基础。接下来，可以进行一些special的听写，尝试听stand English。这个阶段真是打击你信心的时候^^：听写...

[30%]b) Air enters a gas turbine system with a velocity of 105 m/s and has a specific volume of 0.8m3/kg. The inlet area of the gas turbine is 0.05m2. At exit the air has a velocity of 135 m/s and has a specific volume of 1.5m3/kg. In its passage through the turbine system, the specific enthalpy of the air is reduced by 145kJ/kg and the air also has a heat transfer loss of 27 kJ/kg. Determine:i) The mass flow rate of the air through the turbine.ii) The exit area of the turbineiii) The power developed by the turbine system in kW.[70%]2. Answer all parts of this questiona) A turbine operating on a steady flow rate of nitrogen is to produce 0.8kW of power by expanding nitrogen from 300kPa, 350K (inlet specific volume of 0.346 m3/kg) to 120kPa. For preliminary design, the inlet velocity is assumed to be 50m/s and the expansion will be considered as a quasi-equilibrium process such that PV1.40 = constant.Determine the required flow rate. All assumptions must be clearly stated. [40%]b) A mass of 1.32 kg of fluid is contained in cylinder at an initial pressure of 12bar. The fluid expands reversibly and moves a piston according to the law PV2= constant, until the volume is increased by 200%. The fluid is then cooled reversibly at constant pressure until the piston moves back to its original position. Heat is then supplied reversibly with the piston firmly locked in position until the pressure rises to the original value of 12 bar. Sketch the process and calculate the net work done by the fluid, for an initial volume of 0.11 m3. [60%]EE1TF13EE1TF1 Turn Over3. Answer all parts of this questiona) An unknown mass of ideal gas occupies 370ml at 16oC and 150kPa. What is its volume at -21oC and 420kPa?
