问题     During the last decade computers have developed at such an enormous speed in terms of capacity,  efficiency and versatility that they have practically "invaded" almost each and every human  domain(领域). They have undoubtedly gone far beyond the expectations of a generation that had already lived under the spell(一段时间) of the TV set.
   Throughout history there have been inventions that have been particularly remarkable and  influential(有影响力的) within the scope of transport, education, health or communication. They have brought out comfort, health, knowledge or power. Some of them have produced minor effects; others have brought about very great changes. Think of the invention of the wheel, the automobile or the printing press, and what about the computer?
   At the beginning the computer was thought mainly as an instrument to be used in the mathematical field, but soon people from other sciences began to get interested in this little "brain" that was capable of performing thousands of operations in a few seconds without getting tired or confused.  They realized it could not only store millions of pages of information but also organize it in every possible way enabling man to carry out tasks unthinkable by other means.
   Computers are now everywhere. They can make vehicles at supersonic(超音速的) speed and precision; they can control world banking transactions(交易), predict weather conditions, conduct an aircraft or a space craft, play instruments, manage nuclear weapons; they can operate on human  patients, they can transfer information from one continent to another in seconds, they can... they can... they can... Yet, thank God, they still need human beings: to draw the instructions, to design the programs or to push the button!
选项 A、All inventions have brought about complete changes.
B、Few of the inventions have brought about minor changes.
C、The inventions of the wheel and the automobile are not remarkable and influential.
D、We’ve benefited from the comfort, health, knowledge or power brought out by the inventions.
答案D
解析 第二段第二句表明发明给我们带来舒适、健康、知识和力量。
