[单项选择]Science and new technology have made such rapid progress in agriculture that modern machines can do almost all farm work, and therefore have made it possible for farmers to pro- duce more food on the same amount of land. When people live in plenty, vegetables and fruits are becoming more and more popular. As a result more and more vegetables and fruits are in greater need.
Can orchard workers harvest fruits with machines as farmers to crops Yes, they can. Scientists have already invented many different fruit-harvesting machines. Now, let’s take cherry picking machine for example. The cherry-picking machine first shakes a cherry tree, then catches cherries in heavy sheets and pushes the fruit along belts. The cherries are then dropped into huge containers of water, in which they are washed clean, and look fresh and pretty when they are placed into plastic boxes which come along the belt one after another. All this work is finished within three minutes. In this way two orchard worke
A. are on the belts, fresh and pretty
B. are soaked in a large container of water
C. are in heavy sheets, unwashed and dirty
D. have been put into plastic boxes, fresh and clean

[单项选择]Physicists have made new discoveries that challenge our（）theories of the universe.
A. existed
B. adapted
C. accepted
D. established

[单项选择]Modem technology and science have produced a wealth of new materials and new ways of using old materials. For the artist this means wider opportunities. There is no doubt that the limitations of materials and nature of tools both restrict and shape a man’s work. Observe how the development of plastics and light metals along with new methods of welding has changed the direction of sculpture. Transparent plastic materials allow one to look through an object, to see its various sides superimposed on each other (as in Cubism or in an X-ray). Today, welding is as prevalent as casting was in the past. This new method encourages open designs, where surrounding and intervening space becomes as important as form itself.
More ambiguous than other scientific inventions familiar to modem artists, but no less influential, are the psychoanalytic studies of Freud and his followers, discoveries that have infiltrated recent art, especially Surrealism. The Surrealists, in their struggle to escape t
A. can cause a lot of changes in sculpture arts
B. permit details of an object to be seen clearly
C. can superimpose multiple sides of sculptor’s designs
D. can make artists adaptable to be surroundings
