題目列表(包括答案和解析)
The Florida sun baked my shoulders as I worked along the I-595 freeway near Fort Lauderdale, picking up rubbish. I paused to 36 the sweat off my forehead and look up at the cloudless blue sky.“ 37 can’t it rain?” I thought. That would 38 things down.
I thought about my 39 , who were probably sitting in an air-conditioned 40 right now. I’d had some problems in school, 41 my parents decided to let me 42 full-time with my dad, We both worked for my uncle, who had taken 43 of a maintenance（道路養(yǎng)護）company. It was up to us to keep the roads 44 of rubbish. The job was 45 and dirty, especially on hot days 46 this. I wondered why I ever agreed to do it.
We continued our 47 route along the I-595, 48 for the overpass bridge. Then I noticed an area where some 49 were broken on the ground. It wasn’t like that before.
“Dad! Pull over! I want to 50 something out.”
I jumped off the truck and rushed to the bridge. Something was telling me to 51 …there wasn’t much time. 52 I saw a Toyota that 53 upside down in the tree. Maybe it was a stolen car that somebody 54 there, I thought. Then, just at that 55 , I noticed something moving. It was a bloody leg poking out of the driver’s side window!

The basics of infrastructure design
It is rightly pointed out various intellectuals that the lifestyle of today is vastly different from that of the earlier times especially in terms of its pace. Lifestyle of today is remarkably fast paced and so in order to catch up with such a pace of life, the adoption of smart and time saving methods is of real significance. Well, the highways have certainly contributed in this direction and have made our lives a lot easier. Thanks to the modern flyovers and expressways, a single route can be accessed by twice the number of vehicles at the same time.
These facilities and supplies have made our lives double free but it needs to be realized that designing and constructing it is a very complex and a long process. You have to hold fast to the various rules of designing, government standards and most importantly, their safety and usability for the people. In the end it is a joint effort of a number of skilled engineers, scientists and statisticians. The material that is used in the construction is finalized after it undergoes certain tests for evaluating their qualities like hardness, roughness, thickness and all that is required.
Some of the points you have to take care of while laying an infrastructure design are as follows:
The basic layout (布局) of the road — At this level of planning, various civil engineers have meetings to figure out the basic requirements of the road like thickness of the asphalt (瀝青), the size of lanes, distance to be covered, degree of curves and much more. These fundamental points help them decide the further line of action.
The prior steps — Before any work is stated over the basic plan layout, there are various preparations to be made like placing road signs, the removal of trees that may prove to be dangerous in the event of a storm or other natural causes, the positioning of fire hydrants (消防栓) based on special designs to be useful when required, etc.
Inclusion of safety barriers — The safety barriers are placed on almost all roads and highways that are made over or near to rivers and cliffs. These barriers keep the vehicles from moving into the traffic in instances of accidents. These should also be designed in advance of placing them on a road and the design should be such that it makes minimum impact upon the people sitting in the car. These include supplies like side rails and light poles.
Asphalt pavement marking — It is the process of using a reflective material to indicate various important points on the road like lanes, turns, passing areas, two way and one way roads.
Though the smooth and wide highways constructed in big cities seem to be very attractive for the drivers, the ease of use is also the cause of accidents. Cars rushing at extremely high speeds and insecure change of lanes are a common sight on the highways. With the help of novel infrastructure design engineers, we can make the best possible use of highways. If these are designed properly and sign boards are placed at the required points, a number of road accidents can be avoided.
