8.Many managers have access to your computer and can watch ______ you are doing on your screen in real time.(  )
A.howB.ifC.whatD.when

分析 很多经理能够进入你的电脑,看到现实中的你在电脑上做什么.

解答 答案:C 题干中you are doing on your screen in real time充当watch的宾语从句;从句中doing缺少宾语,要用连接代词.故选C.

点评 在句子中起名词作用的各种从句统称为名词性从句.根据它们在句中的语法作用,这类从句又可分为主语从句、同位语从句、表语从句和宾语从句. 本题中what在宾语从句中起连接作用,同时又充当了从句的宾语.

4.The Most Fantastic Staircases in the World
Infinity and beyond
The architecture of the staircase combines form and function,upper and lower space.It can represent power or status,or symbolize spiritual uplift and the climb to knowledge.A new book published by Thames&Hudson,The Staircase:The Architecture of Ascent explores the history and meaning of the staircase,from the simple,straight-fight steps of the Mayan pyramids,to the spiral ramp(螺旋型坡道)of Frank Lloyd Wright's Guggenheim Museum and the computer-aided designs of today.
The steps of the Toltec-Maya pyramid at Chichen Itza is the ancestor of all stair design.Appearing to stretch up to the sky,this style of staircase came to symbolize a rise to heaven and infinity,and has captured artists'imaginations.
Let there be light
The"lantern"at the dome(圆顶屋)of a staircase is an important design feature----allowing the light to stream in.The view shown here of the lantern of the Chateau of Chambord in the Loire,France,shows the flat ceiling decorated with coffering(方格天花板).The Chateau marks a high point in the development of the staircase,reflecting the Renaissance(文艺复兴) architects'liking for the spiral structure around an open space.
High and mighty
The spirit of the Baroque(巴洛克)appears in the monumental staircase of the Palazzo Canossa in Mantua,Lombardy,Italy,built in the 1600s for the Gonzagafamily,who ruled that part of northern Italy from the14th to the 18th centuries.The figures that greet the visitor on the landing include two large dogs,symbolizing the powerful family.
High drama
The palaces of Germany and Austria showGerman Baroque at its most dramatic and rich.At the Würzburg Residenz,the ceiling is covered in a painting by Venetian artist Giambattista Tiepolo describing the four comers of the earth above the great staircase.

60.The stair designers of today draw inspiration fromB.
A.the Guggenheim Museum    
B.the Toltec-Maya pyramid
C.the Chateau of Chambord      
D.the Würzburg Residenz
61.Which of the following designs would probably be of the Renaissance style?C
A.A simple,straight staircase.
B.A flat ceiling left bare.
C.A spiral staircase with careful decoration.
D.A plain dome of a staircase.
62.The staircases of the Palazzo Canossa and the Würzburg ResidenzA.

2.American cities are similar to other cities around the world:In every country,cities reflect the values of the culture.American cities are changing,just as American society is changing.
After World WarⅡ,the population of most large American cities decreased; however,the population shifts(转移)to and from the city reflect the changing values of American society.In the late 1940s and early 1950s,city residents(居民)became wealthier.They had more children so they needed more space.They moved out of their apartments in the city to buy their own homes.They bought houses in the suburbs(郊区).
Now things are changing,The children of the people who left the cities in the 1950s are now adults.Many,unlike their parents,want to live in the cities.They continue to move to Sun Belt cities and older ones of the Northeast and Midwest.Many young professionals are moving back into the city.They prefer the city to the suburbs because their jobs are there; or they just enjoy the excitement and possibilities that the city offers.
This population shift is bringing problems as well as benefits.Countless poor people must leave their apartments in the city because the owners want to sell the buildings or make apartments for sale instead of for rent.In the 1950s,many poor people did not have enough money to move to the suburbs; now many of these same people do not have enough money to stay in the cities.
