广东省各专业工程
定额运距计价区别
一、建设工程：粤建市[2010]15号
土石方运输子目适用于运距在30KM以内的运输，
超过30K部分按照每增加1KM相应定额子目乘以系数0.65计算。
二、交通工程：JTGB06-2007 交通部2007第33号
自卸汽车运输路基土石方定额项目，仅仅适用于平均运距15KM以内的土石方运输，
当平均运距超过15KM时，应按照社会运距的有关规定计算其运输费用。
当运距超过第1个定额运距单位时，
其中：
运距尾数不足一个增运定额单位的半数时不计，
等于或者超过半数时按照1个增运定额运距单位计算。
三、水利工程：粤水基【2006】2号文
汽车运输定额，适用于地方水利水电工程施工路况6KM以内的场内运输。
当运距大于6KM，超出部分按增运定额的台班数乘以系数0.75计算；
当运距大于30KM，超出部分按增运定额的台班数乘以系数0.65计算；
四、轨道交通工程：GCG103-2008建标[2008]193号
土石方水平运距是按照最远开挖点距离工作井800M以内考虑的。
若最远开挖点距离工作井在800-1200M以内，超过800M部分土石方水平运距机械消耗量乘以系数1.15；
若最远开挖点距离工作井在1200M以外，超过1200M部分土石方水平运距机械消耗量乘以系数1.25。

And anyone who isn’t living cannot have the job.”The man left with no hope at all. He didn’t know what to do with only $10 in his pocket. He thought and thought. Then he went to the supermarket and bought 10 kilos of tomatoes. He sold the tomatoes from door to door. In less than two hours, he had 20 dollars. He repeated the operation three times, and started to go early every day, and returned home late. Shortly, he bought a cart(手拉车) , then a truck, then he had his own fleet of delivery vehicles(运货车队). Five years later, the man was one of the biggest food retailers (零售商) in the US.One day, one of his friends asked him for his e-mail.

Nothing in the world is impossible if we w ork hard.CYou’ve probably seen it before－two elderly people walking hand in hand down the street and looking very much like each other. They look so much alike that they could be brother and sister.Do you believe that people who live together for many years would look alike? It’s strange. but scientists say it’s true.How scientists proved it? In a study, scientists found young couples only showed similarity by chance. However, elder couples were very likely to look like each other. The similarity could be very subtle(微妙) and could be found in wrinkles(皱纹) or furrows, etc. Besides, some couples look far more alike than other couples.The scientists thought of several possible reasons:1. Diet. “We are what we eat.” As couples usually share the same diet, will they probably look alike? For example, if both partners eat a high fat diet, their faces will tend to look fat. However, the scientists ruled this out(排除) using another small study.2. Environment. Will elderly couples show similarity because they live together in the same area for a long time? The environmental factors(因素) such as sunshine and wind affect the skin in similar ways. The scientists ruled this possibility out as well.3. Empathy(移情作用). This is the theory(理论) the scientists believe in. Couples grow to look similar because they are empathizing with each other. They copy each other’s facial expressions. For example, if one partner often smiles in a certain way, the other is likely to copy it. In this way, their faces share similar wrinkles and furrows.( )51. The old couples look ________ than the young couples.A. much more alikeB. more differentC. less alikeD. 1ess different ( )52. Scientists think that the old couples look alike in their ________.A. agesB. educationC. appearanceD. abilities( )53. How many reasons did the scientist think of about it?A. One.B. Two.C. Four.D. Three( )54. Which of the following is NOT true?A. Your diet can affect your appearance.B. You will look slim if you eat a high fat diet.C. Old couples look similar because they are empathizing with each other.D. Old couples usually share similar wrinkles and furrows.( )55. Which is the theory the scientists believe in?A. Empathy.B. Diet.C. Environment.D. Wrinkles.DNever try to work when you are very hungry. If you decide to do your homework right after school, you may get something to eat before getting to work. Always do your homework before you get too tired. Don’t wait until very late in the evening, or your work will seem much harder than it really is.If you have more than an hour’s work, give yourself a break after an hour. On the other hand, don’t break it up so much that you can’t get anything done ,you should be able to work at least a half at a time without stopping.Don’t put it off until t he last minute. If you put off doing your homework, you will have it on your mind, and you won’t enjoy your free time so much. If you put it off until the end of the week or until right before a test, you will have too much catching up to do. A little bit each night enough to keep up with what is happening each day in school, will take the fear out of tests and keep you on top of it all.Do your homework at the same time every evening. This will help you make it a habit. It will make it easier to do and it will make your free time more enjoyable, as well.( )56. If we wait very late in the evening, our work will ___________.A. become a bit hardB. seem much harderC. look very easyD. go to so much trouble( )57.

You have to sit down and write a thank-you note. The words “thank you” are very important. We have to use them on many occasions. We say them when someone gives us a drink, help us to pick up things, hands us a letter, lends us a book or gives us lift.(1)______ important word is “please”, _____ many people forget to use it. (2)It is impolite to ask someone to do something without saying “please”.We have to use it when we ask for something , too. It may be a book or a pen, more rice or more milk, help or advice. It may be in the classroom, at home, at the bus stop or over the counter. We have to use “please” to make request pleasant.We have to learn to say “sorry” too. When we have hurt someone’s feeling, we will have to go up and say we’re sorry. When we have told a lie and feel sorry, we will have to use the same word. When we have forgotten something or broken a promise, we will have to explain with that word, too. “Sorry” is a healing w ord. We can make people forget wrongs by using it sincerely.“Thank you! Please! Sorry!”—these words are simple but important. Man had to use them long ago. We have to use them now. Our children will have to use them again.1. 在(1)句空白处填上恰当的词使句意完整、上下文通顺:____________ 、____________2 将(2)句译成汉语。
