(2016·银川检测)

As a boy，like many others，I used to love looking through maps.My family spent

the 1 holidays beside the coast in Dorset，in southern England，and on the 2 of the cottage where we stayed there was a large framed 3 of an Ordnance Survey map from 1963, 4 the surrounding area at a scale of six inches to one mile.

5 it rained — which，since this was summertime in Britain，was very often — I would

6 this black－and－white map，marvelling (感到惊奇) at its complex system of marks and symbols.

Even today，when I go for a long walk in the countryside，I still like to 7 an OS Explorer map.It's 8 than, say, an app on my smartphone，which is prone to run out of power，or losing its 9 ．

This is the thing about maps: properly 10 ，they feel objective and authoritative (权威性的 ) — 11 tools that allow us to locate ourselves within the world.Indeed，the Ordnance Survey，Britain's famous mapping agency, still 12 itself on being as comprehensive and 13 as possible.

Today it has 14 developed into a digital powerhouse maintaining an enormous 15 of geographical information.All of its maps are produced from

its 16 “OS MasterMap” of Great Britain，which 17 more than

460 million geographic features and is continually 18 —astonishingly，more than 10，000 times a day — by a team of 270 surveyors using GPS 19 ．“Our survey is to centimetre accuracy，” explains OS sector manager Elaine Owen，“our mapping database is the most 20 geographical database in the world.”

本文为说明文，主要介绍了OS Explorer map，该地图对地形和地点描述精确，有助于

游人探险。

1．A.spring B．summer

C．autumn D．winter

B[考查语境选词。由下文中的“since this was summertime in Britain”可知，此

处只有summer符合题意。]

2．A.floor B．wall

C．TV D．desk

B[考查语境选词和常识。由常识可知地图一般是挂在墙上的，故选B。]

3．A.sheet B．book

C．picture D．paper

A[考查语境选词。由本句可知墙上挂着的是英国测绘局1963年印制的一张大型地图，再由本文的主题可判定选项中的picture，book不符合题意。而选项D中的paper“纸”为不可数名词，不与a large连用。所以A项sheet“一张”符合题意。]

4．A.drawing B．representing

C．dotting D．charting

D[考查动词辨析。本文讲的是地图，在这儿作者暗示地图制作精致，该图对周围地形的制图标准是“图上六英寸，实际一英里”。所以本题应填与绘图有关的词语。draw“描绘”，多指手绘；represent“描绘，展示”；dot“加点于”；chart“绘制(区域)的地图”。故选D。]

5．A.However B．Wherever

C．Whenever D．If

C[考查语境选词。根据语境可知，此处表示只要天一下雨，作者就会待在家里研究地图。所以C项whenever符合题意。]

6．A.study B．write

C．read D．observe

A[考查语境选词。参考上题解析可知，此处表示只要天一下雨，作者就会待在家里研究地图。英语中表示看地图一般用study，所以选A项。]

7．A.buy B．borrow

C．pack D．draw

C[考查语境选词。由本文首句“As a boy，like many others，I used to love looking through maps.”可知，作者喜欢地图。此处是说作者无论到哪里都喜欢带上一份地图。所以pack“塞进，装”符合题意。]

8．A.cheaper B．more reliable

C．more convenient D．simpler

B[考查语境选词。空格后面提到“an app on my smartphone，which is prone to run out of power，or...”，由此可推知作者认为地图比智能手机上面的app可靠。] 9．A.map B．systems

C．information D．signal

D[考查生活常识。依据常识可知手机的不便之处除了比较容易没电之外就是没信号，所以D项signal“信号”符合题意。]

10．A.carried B．packed

C．produced D．studied
