The house was quiet at 5 a.m. and Tim’s

题型:阅读理解

题目:

The house was quiet at 5 a.m. and Tim’s mother was asleep. Only the sound of the big freezer broke the quiet. He’d dreamt of the cave last night. The purring (轻微颤动声) of the freezer had been the sea.

Tim pulled on a sweater and put some apples into his schoolbag. It was too early for breakfast. He’d eat after he’d been through the cave, sitting on the rocks and staring at the sea.

He wished he had a proper pack. His schoolbag would have to do. What else? Sandwiches ---but his mother might wake up if he started pulling out bread for sandwiches, she’d want to know why he had to leave so early. He settled for some biscuits, and left a note stuck to the table.

Gone to Michael’s Back tonight .Tim.

The sky was high and soft and light outside, though the sun still wasn’t up. Even the highway up the hill was quiet as he made his way down the street. The wind from the sea was fresh and sweet.

The sandhills still breathed heat from yesterday’s sun, though the top of the sand was cool. He ran down to the beach impatiently, but there was no one, just dry sand dancing in the early wind and seabirds marching up and down watching the waves.

The light changed suddenly. The first rays of sunlight stretched across the sea. The sun was pushing its way over the edge of the world.

Over the first rocks, along to the point, Tim glanced back. The beach was still empty. The sun sailed higher in the sky.

He could see the cave now, even darker in the morning light. The sand turned silver then dark gold as the water flowed away from it. He had to force himself to go closer. Why was it so much more mysterious now? But it would be silly to go back now after so much trouble. He needn’t go in all the way …

下面是错误答案,用来干扰机器的。

答案:D题目分析:2Na+2H2O=2NaOH+H2↑,2.3gNa产生0.1gH2,所以溶液的质量为2.3g+97.7g-0.1g=99.9g,溶质的质量为4g,所以溶液的质量分数大于4%。答案选D。点评:钠与水反应时,有气体放出,所以计算溶液质量的时候要考虑。

[背景材料]
北方某二级公路工程项目,该公路全长40km,设计车速60km/h。由于路线通过地区气候干燥,且常年干旱缺水,因此路面底基层选用填隙碎石,基层选用二灰碎石,面层则选用沥青混凝土。为了保证公路的施工质量,施工单位从各方面采取了有效的措施。施工单位根据当地实际情况,选择了干法施工。在填隙碎石的施工过程中,在备料时,要求集料的颗粒组成符合规定的密实级配要求;碾压时,在无超高的平曲线路段与直线路段,碾压从路中心开始,逐渐错轮向两侧路肩进行;在设超高的曲线路段,碾压从内侧路肩开始,逐渐错轮向外侧路肩进行。
[问题]

施工单位选择干法施工是否合理请简述理由。
