职称英语综合类补全短文第四篇The First Four Minute逐句翻译
The First Four Minutes最初四分钟When do people decide whether or not they want to become friends?人们什么时候决定他们是否愿意成为朋友？During their first four minutes together, according to a book by Dr. Leonard Zunin. In his book, “Contact：The first four minutes" he offers this advice to anyone interested in starting new friendships：“Every time you meet someone in a social situation, give him your undivided attention for four minutes.(1) A lot of people's whole lives would change if they did just that. ”按列奥纳多?祖尼博士的书中所说是在他们相处的最初四分钟。
在他的书《接触：最初四分钟》里，他向所有对开始新的友谊感兴趣的人们提出了这样的建议：“每次你在社交场合遇到什么人时，全神贯注地注意他四分钟。
如果这样做了的话，他们的生活就会完全不同。
”；You may have noticed that the average person does not give his undivided attention to someone he has just met. 你可能已经注意到了，一般人都不会全神贯注地注意一个他刚认识的人。
(2) He keeps looking over the other person's shoulder, as if hoping to find someone more.他不停地往其他人身后看，好像要在屋里其他地方找到更趣的人似的。

他是彼得的朋友。
他们正在庆祝他的九岁生日。
分析句子结构可知，第一空所在句子是定语从句，先行词是人，连接词在从句中作主语，所以应该用who/that引导，which连接定语从句时先行词应该是物，故排除C；nine九，基数词；ninth第九，序数词；第二空根据空后的birthday为名词单数可知，此处需要序数词，表示某人几岁生日应该用序数词表示第几个生日，故选A。

be 句式的疑问句，把be 动词提到句首．there be 句型中，be动词根据就近原则做出变化，a ruler离be动词近，所以be用is，There be 的否定回答是No，there isn't．故答案是：Is，isn't．【答案】Are,any,aren't【考点】疑问词组不定代词【解析】我们学校有一些音乐教室吗？不，没有．【解答】答案：Are，any，aren't．本题考查There be句式的一般疑问句与不定代词，music rooms音乐教室是复数，句子开头be动词要用are，疑问句中some 变成any，there be 句式否定回答No，thereisn't/aren't．故答案是：Are，any，aren't．【答案】不可数名词一般疑问句【解析】玻璃杯里有果汁吗？是的，有．【解答】答案：Is，is．本题考查be动词与不可数名词，there be 的一般疑问句是把be

room翻译为美术教室，二者是放在一起作为一个名词来讲的，因此变复数直接在room的词尾加s，所以答案是art，而不是arts．【答案】any【考点】不定代词【解析】我们学校有一些音乐教室吗？【解答】答案：any．本题考查不定代词，There be 句型的疑问形式是把be动词提到句首，用any表示"一些"；肯定句用some表示"一些"．【答案】mangoes【考点】可数名词及其单复数【解析】你们学校有多少芒果树？【解答】答案：mangoes．考查可数名词的复数形式．how many

动词要用单数is．句首大写字母，故答案是Is．【答案】the first【考点】序数词【解析】这是一周的第一天．【解答】答案：the first．本题考查序数词的用法．根据语境It is﹣﹣（one） day of the week（星期）．可以推知句意为这是一周的第一天，这里表示第几天应该用序数词，序数词前面一般加定冠词the．one的序数词是first．故填first．五、根据上下文完成对话．【答案】Are,Thereare,Are,any,they're,aren't【考点】补全对话【解析】安：你好，杰克．欢迎来到我们的学校．杰克：谢谢．你的学校里有很多花吗？安：是的．也有一些树．杰克：有乒乓球室吗？安：有，它们在三楼．杰克：有多少间音乐教室呢？安：对不起，这里没有音乐教室．【解答】（1）根据"___there a lot of flowers in your school？"可推测是询问"你的学校有很多花吗？"是there be句型的一般疑问句形式，把be提到句首．因为a lot of flowers是复数，所以be用复数are，句首大写，故填Are．（2）联系上句，可知此句意为：也有很多树．用there be句型表示"某地存在某物"，由于some trees是复数，句首大写．故填There are．（3）there be句型的一般疑问句是把be提到句首，be的单复数由主语决定．table tennis rooms是复数，所以开头要用Are．复数名词前可用some或any修饰，在一般疑问句中常用any．故本题填Are，any．（4）联系上文"有乒乓球室吗？答句意为：有，它们在三楼，可知空缺的地方是指乒乓球室．用they指代乒乓球室，table tennis rooms是复数，用谓语动词are．故填they're．（5）联系上文"有多少间音乐教室呢？"根据关键词Sorry，以及出现在否定句中的any可知是否定回答．故填aren't．六、阅读短文并判断，相符的写T，不相符的写F．【答案】F,F,F,F,T【考点】判断正误【解析】Kate是一名新学生．她十二岁了．她来自于美国．她英语说的非常好而且能说点中文．她在南京．她的父母都是医生．Kate 在她家附近的一所学校学习．她从星期一到星期五上课．在周六和周日，她经常和她的中国朋友做游戏，她喜欢中国和她的中国朋友们．【解答】（1）F 考查点判断正误，根据原文的第三句"She is from America"可知Kate来自于美国，不是来自于中国，故判断为"F"．（2）F 考查点判断正误，根据原文的第四句"She can speak English very well and she can speak a little Chinese．"Kate 会说点中文，并不是不会说．故判断为"F"．（3）F 考查点判断正误，根据原文的"Her parents are doctors．"可知她的父母都是医生，这说明她的爸爸也是一名医生．故判断为"F"．（4）F 考查点判断正误，根据原文的"She has some classes from Monday to Friday"可知她周一到周五有课，故判断为"F"．（5）T 考查点判断正误，根据原文的"On Saturdays and Sundays，she often plays games with her Chinese friends"她在周六和周日经常和她的中国朋友们做游戏，故判断为"T"．试卷第11页，总11页。

The first postal service 阅读理解
The first postal service 阅读理解Passage ThreeThe first postal service in North America began in New England in the 17th century. All mail arriving in Massachusetts colony was sent to the home of appointed official in Boston. In turn, the mail would be delivered from Boston on horseback to its destination, receiving one penny for each good article of mail. Later in the century postal services were established between Philadelphia and Delaware. In 1691,(33) (34) the British crown appointed the first postmaster general to have charge of the mail for all the colonies in North America. Later, Benjamin Franklin served as the postmaster general for the British government and then (35) was made postmaster by the newly formed United States' postal systems on a permanent basis. He increased the number of post office, introduced the use of stagecoaches to carry mail, and started a package service system. They were used to carry mail into the towns. Some communities, especially those out west, were far from the services of transportation. To serve them, the post office developeda system called"star routes".Private contractors paid to deliver mail to the communities from railways by horse and wagon.(32) The postal service, which was started 3 centuries ago, has developed into an extensive government service with post offices in every city, town, and village in the United States.32. What is the main topic of this passage?B)。

19、解法一：设y为流出的水中杂质的质量分数，则y=k/ab，其中k>0为比例系数，依题意，即所求的a,b值使y值最小。
根据题设，有4b+2ab+2a=60(a>0,b>0)，
得b=30-a/2+a (0<a<30)，①
于是y=k/ab=k/((30a-a2)/(2+a))
=k/(-a+32-64/(a+2))
=k/(34-(a+2+64/(a+2))
当a+2=64/(a+2)时取等号，y达最小值。
这时a=6,a=-10（舍去）。
将a=6代入①式
得b=3。
故当a为6米，b为3米时，经沉淀后流出的水中该杂质的质量分数最小。
解法二：依题意，即所求的a,b的值使ab最大。
由题设知4a+2ab+2a=60 (a>0,b>0)，
即a+2b+ab=30 (a>0,b>0)。
∵a+2b≥2，
∴
2+ab≤30，当且仅当a=2b时，上式取等号。
由a>0，b>0，解得0<ab≤18。
即当a=2b时，ab取得最大值，其最大值为18。
∴2b2=18。
解得b=3，a=6。
故当a为6米，b为3米时，经沉淀后流出的水中该杂质的质量分数最小。

20、解：（Ⅰ）作A1D⊥AC，垂足为D，
由面A1ACC1⊥面ABC，得A1D⊥面ABC，∴∠A1AD为A1A与面ABC所成的角。
∵AA1⊥A1C，AA1＝A1C，∴∠A1AD＝45°为所求。
（Ⅱ）作DE⊥AB，垂足为E，连A1E，则由A1D⊥面ABC，得A1E⊥AB。
∴∠A1ED是面A1ABB1与面ABC所成二面角的平面角。
由已知，AB⊥BC，得ED∥BC。
又D是AC的中点，
BC＝2，AC＝2，∴DE＝1，AD＝A1D ＝，
tgA1ED＝A1D/DE=。
故∠A1ED＝60°为所求。
（Ⅲ）解法一：由点C作平面A1ABB1的垂线，垂足为H，则CH的长是C到平面A1ABB1的距离。
连结HB，由于AB⊥BC，得AB⊥HB。
又A1E⊥AB，
知HB∥A1E，且BC∥ED，∴∠HBC＝∠A1ED＝60°。
∴CH＝BCsin60°＝为所求。
解法二：连结A1B。
根据定义，点C到面A1ABB1的距离，即为三棱锥C－A1AB的高h。
由V锥C－A1AB＝V锥A1－ABC得1/2S△AA1Bh＝1/2S△ABCA1D，
即 1/3×2h=1/3×2
×∴h= 为所求。
21、（Ⅰ）解：曲线C1的方程为y=(x-t)3-(x-t)+s。
（Ⅱ）证明：在曲线C上任取一点B1(x1,y1)。
设B2(x2,y2)是B1关于点A的对称点，则有x1+x2/2=t/2, y1+t2/2=s/2。
∴x1=t-x2, y1=s-y2。
代入曲线C的方程，得x2和y2满足方程： s-y2=(t-x2)3-(t-x2)，
即y2=(x2-t)3-(x2-t)+s，可知点B2(x2,y2)在曲线C1上。
反过来，同样可以证明，在曲线C1上的点关于点A的对称点在曲线C上。
因此，曲线C与C1关于点A对称。
（Ⅲ）证明：因为曲线C与C1有且公有一个公共点，
所以，方程组 y=x3-x, y=(x-t)3-(x-t)+s
有且公有一组解。
消去y，整理得
3t x2-3t2x+(t3-t-s)=0，这个关于x的一元二次方程有且仅有一个根。
所以t≠0并且其根的判别式△=9t4-12t(t3-t-s)=0。
即 t≠0, t(t3-4t-4s)=0。
∴s=t3/4-t 且 t≠0。
22、（Ⅰ）解：曲线C1的方程为y=(x-t)3-(x-t)+s。
（Ⅱ）证明：在曲线C上任取一点B1(x1,y1)。
设B2(x2,y2)是B1关于点A的对称点，则有x1+x2/2=t/2, y1+t2/2=s/2。
∴x1=t-x2, y1=s-y2。
代入曲线C的方程，得x2和y2满足方程： s-y2=(t-x2)3-(t-x2)，
即y2=(x2-t)3-(x2-t)+s，可知点B2(x2,y2)在曲线C1上。
反过来，同样可以证明，在曲线C1上的点关于点A的对称点在曲线C上。
因此，曲线C与C1关于点A对称。
（Ⅲ）证明：因为曲线C与C1有且公有一个公共点，
所以，方程组 y=x3-x, y=(x-t)3-(x-t)+s
有且公有一组解。
消去y，整理得
3t x2-3t2x+(t3-t-s)=0，这个关于x的一元二次方程有且仅有一个根。
所以t≠0并且其根的判别式△=9t4-12t(t3-t-s)=0。
即 t≠0, t(t3-4t-4s)=0。
∴s=t3/4-t 且 t≠0。
