题目内容
11.A new eight-kilometre road is under construction that links the port area with the motorway system.It is expected to carry 20,000trucks and cars a day,which greatly reduces the overcrowded traffic in the center of the city.As part of the project,two four-kilometre road tunnels are being built below the central area of the city,one for traffic to the north and the other for traffic to the south.The two tunnels are about 20metres below the surface and are 12metres wide,providing for two lanes of traffic in each direction.In the upper part of the tunnel two air-conditioning pipes remove the waste gas of trucks and cars and keep the quality of air inside the tunnel.The lighting is at the top of the tunnel,practically at its highest point.There will also be electronic signs at frequent intervals (间隔).They show traffic conditions ahead,and can be seen clearly by drivers.The wall is made up of four main elements,which include a waterproofing covering and,on the inside of the tunnel,a concrete lining (混凝土衬砌).
Each tunnel is roughly round and the lower part of the tunnel is somewhat flat.The surface of the road lies on the base,which is made of concrete and steel.The drainage system (排水系统),just below the road surface on one side,removes any extra liquid,particularly water.In the event of fire,the fire main,which is made of steel,pipes water to many fire hydrant stations at regular intervals along the length of the tunnel.The fire main is at the side of the tunnel,and at the level of the road surface.Other systems in the tunnel will include emergency phones.
12.Each of the tunnels under construction isD.
A.eight kilometers long and twelve metres wide
B.eight kilometers long and six metres wide
C.four kilometers long and twelve metres wide
D.four kilometers long and six metres wide
13.Which part of the tunnel in the diagram is used to pipe out extra water?C
A.1
B.3
C.5
D.6
14.Driving in the tunnel,one can know the traffic conditions ahead throughB.
A.the lights
B.the electronic signs
C.the trucks and cars
D.the emergency phones
15.The passage is mainly aboutD.
A.the construction of a road
B.the design of a road
C.the construction of two tunnels
D.the design of two tunnels.
分析 文章大意:本文讲的是两个隧道,主要讲的是隧道的内部结构.
解答 12.D 细节理解题.根据文章第一段中的As part of the project,two four-kilometre road tunnels are being built…可知tunnels长4公里;根据The two tunnels are about 20metres below the surface and are 12metres wide可知两个隧道宽12米,一个隧道宽6米.因此答案选D.
13.C 推理判断题.根据文章第三段的The drainage system (排水系统),just below the road surface on one side,removes any extra liquid,particularly water可知排水系统正好在路表面一侧的下方,对照剖面图,5符合这个位置.因此答案选C.
14.B 推理判断题.根据文章第二段中的will also be electronic signs at frequent intervals (间隔).They show traffic conditions ahead,可知电子告示的作用是显示交通状况,因此答案选B.
15.D 主旨大意题.根据整体内容可知,这篇文章主要讲的是两个隧道,因此排除A、B两项;文章讲到的是隧道的内部结构,因此C项"两个隧道的建设"也是错误的,因此答案选D.
点评 本文是新闻报道类阅读理解.这类题材是高考常考的内容.它注重考查考生对整体文章的把握,要求考生在考试时要通读全文,了解大意,还要结合题目要求以及上下文做出正确的选择.
