Answer the questions on each text by choosing A, B, C or D. Today there are three different kinds of New Yorkers: the people who act as if they were born here: the people who are here and wish to be elsewhere: and the collection of virtual New Yorkers all over the world, who wish they were living in New York. These are the three states of mind and what they have in common are longing and illusion. In fact, it´ s a city of dreamers.What makes New York special? New Yorkers are convinced of its specialness—but Toronto is more diverse, London is larger, Washington is more powerful. So why does New York think it´ s the capital of the world?People often explain the problems in European cities by citing inequality. But New York today is one of the most unequal cities in America. In 2010, 1 percent of New Yorkers earned 45 percent of its income. That works out to an average of $3.7 million a year for the city´s top 34,500 households. The average daily income of this group is greater than the average annual income of the city´ s bottom 10 percent.So why would people still come to try their luck in this tough place? Is it opportunity or illusion that draws them?They come because any newcomer can find a place in the hierarchy of New York. If you look at a New York City restaurant, for example, the cook might be French, the people washing dishes might be Mexican, the hostess might be Russian, the owner might be British. They are not all equal. They earn different rates. But they work together to get food to hungry people.What New York demonstrates is this: immigration works. The city can use its immigrants, eventhe illegal ones. Though they broke the law by illegally crossing the borders, the city´ s economy would be a shell of itself had they not, and it would collapse if they were deported. Attracted here by the founding myth of the city, each immigrant is seeking to escape from history, personal and political. For him, New York is the city of the second chance.第46题The writer mentions the three kinds of New Yorkers to stress that______.A.they share the same longingB.they are in pursuit of dreamsC.they are proud of their birthplaceD.they wish to live in another place第47题In the eyes of New Yorkers, their city is______.A.powerfulB.diverseC.specialrge第48题The figures in paragraph 3 are given to show that New York______.A.favors the luckyB.favors the localsC.is a city of inequalityD.is a city of opportunities第49题People keep coming to New York because they can find jobs that______.A.challenge themB.suit them wellC.pay them wellD.raise their status第50题It is implied in the text that New York is______.A.a tolerant cityB.a wealthy cityC.a mythical cityD.a historical city上一题下一题(51~55/共15题)ComprehensionDirections:Read the following two texts. Answer the questions on each text by choosing A, B, C or D.We´ ve read how babies stare longer and cry less when held by pretty people, and heard tales of handsome children doing better in school, given special attention by their teachers. In life, as in love, beautiful people seem to have it awfully easy. But what if we told you that when it comes to online dating, good looks could actually hurt you?According to a recent survey of 43,000 users by OK Cupid, an online dating site, the more men disagree about a woman´s looks, the more they end up liking her. What does that mean for ladies looking for a match? " We now have mathematical evidence that minimizing your´weaknesses´ is the opposite of what you should do," says the site´s co-founder, Christian Rudder. "If you´re a little fat, play it up. If you have a big nose, play it up. Statistically, the guys who don´ t like it can only help you, and the ones who do like it will be all the more excited. "The results of this study end up highlighting an idea that recent scientific research does indeed support. Which is this: the beautiful may have it good, but online, as in work and life, women who are too attractive don´t always have an advantage.Beauty creates more competition—among women, taught they must out-look each other for men and jobs and everyday satisfaction: and among men, who are competing for the most attractive prize. All of which might help explain why 47 percent of corporate recruiters believe it´s possible for a woman to suffer for being " too good-looking": why attractive women tend to face heightened examination from their female peers: or, finally, why men on OK Cupid end up contacting women who may ultimately be less attractive—because it removes the opposition. " If you suspect other men are uninterested, it means less competition," explains Rudder. " You might start thinking: maybe she´ s lonely... maybe she´ s just waiting to find a guy who appreciates her... at least I won´ t get lost in the crowd.

四、简答
1、回转式粗粉分离器工作原理?
答:煤粉气流由下部进入分离器,因流通面积增大,气流速度降低,一部分煤粉在重力作用下被分离出来;气流进入转子区域,被转子带动旋转,粗粉受到较大的离心力而分离出来;当气流沿转子叶片间隙通过时,煤粉颗粒收叶片撞击又有部分粗粉被分离。
分离出来的煤粉回到磨内重新磨制。
2、空气预热器的作用?
答:利用排烟余热加热锅炉燃烧和制粉需要的空气,使排烟温度降低,减少排烟热损失,提高机组的效率。
3、凝渣管作用?
答:形成宽敞的烟气通道以使烟气通过,并进一步冷却烟气,使烟气中携带的飞灰处于凝固状态,防止在炉膛出口和密排的过热器进口处产生结渣现象。
4、为何直流锅炉点火前要进行循环清洗?
答:机组停用时,内部会由于氧化生产氧化铁;锅炉运行时给水中的杂质除部分被蒸汽带走,其余都沉积在受热面上。
为了清除这些污垢,点火前要用一定温度的除氧水进行循环清洗。
5、影响再热汽温的因素?
答:高压缸排气温度;再热器吸热量;再热蒸汽量;减温水量;烟气挡板开度。
