建设工程总分包模式的特点有（）。
A.总承包商的责任重，获利潜力大
B.业主合同结构简单，组织协调工作量小
C.业主选择总承包商的范围大，合同总价较低
D.总包合同价格可以较早确定，业主的风险小
E.承包商内部增加了控制环节，有利于控制工程质量
参考答案：A, B, D, E
解析：采用总分包模式具有以下特点。（1）有利于项目的组织管理。由于合同数量少，使得业主的组织管理和协调工作量小，可发挥总承包商多层次协调的积极性。（2）有利于控制工程造价。由于总包合同价格可以较早确定，业主可以承担较少风险。（3）有利于控制工程质量。由于总承包商与分包商之间通过分包合同建立了责、权、利关系，在承包商内部，工程质量既有分包商的自控，又有总承包商的监督管理，从而增加了工程质量监控环节。（4）有利于缩短建设工期。（5）对业主而言，选择总承包商的范围小，一般合同金额较高。（6）对总承包商而言，责任重、风险大，需要具有较高的管理水平和丰富的实践经验。当然，获得高额利润的潜力也比较大。
Passage Four
| Roger Federer Lights up the Arabian Night 罗杰·费德勒点亮阿拉伯之夜 Plenty of people will be glad Tim Henman was not here to trouble Roger Federer once more last night，as the seedings said he should have been.Popular with the expatriates though he may be，and capable of upsetting Federer though he undoubtedly is，there is nothing quite so stirring as seeing one of the most gifted world No l s of all in full cry. Instead of struggling with his jinx player，Federer imposed a spell of his own.He beat Andrei Pavel，whom Henman beat in the Paris Masters final，by6-3，6-3，and strode the court like a ruler who knows his aura is expanding. It carried the Swiss imperiously into a semi-finals of the Dubai Championships，where he will face Jarkko Nieminen.The Finn earned his place by defeating the Dutch No 8 seed Sjeng Schalken 6-3,6-3. Federer insisted he was not at his best-"I haven’t wanted to chase the fines as much as I should，"he said. Pavel was driven to distraction as it was.He had akeady lifted himself near the level he showed when he was in the top 20.But just when he looked as if he might prolong the second set， Federer struck. He retrieved one ball from deep，outside the tramlines on the forehand side，turned and reached the next ball from short and outside the tramlines on the backhand side，and still somehow hit a controlled winner.It completed the decisive break of serve. Pavel responded by launching a spare ball towards the sky and it landed on the whiskey tables in the lrish village below.The umpire uttered a code violation warning in little more than a whisper.It was as though he felt sympathy for the Romanian. If Federer reaches tomorrow’s final he will play Spain’s Feliciano Lopez，whose Davis Cup debut came in the singles in the 2003 final in Melbourne，or Mikhail Youzhny，whose first Davis Cup experience was as a ball boy in the 1995 final in Moscow. That spurred Youzhny to make a top-level breakthrough seven yearslater，and to develop perseverance which has been revealed this week in a 6-3，1-6，6-1 quarter-final win over Rafael Nadal yesterday in heat which would have made a camel protest，and in a recovery from two days’vomiting after eating Japanese seafood."My cap felt as if it weighed five kilos."he said. |
