THOMAS EDISON
On the night of 21 October 1931, millions of Americans took part in a coast-to-coast ceremony to commemorate the passing of a great man. Lights 【B1】______ in homes and offices from New York to California. The ceremony 【B2】______ the death of an inventor—indeed, to many people, the most important inventor of 【B3】______ time: Thomas Alva Edison.
Few inventors have 【B4】______ an impact as great as his on everyday life. While most of his 1 000- plus inventions were devices we no 【B5】______ use, many of the things he invented played a crucial 【B6】______ in the development of modern technology, simply by showing what was possible. And one should never 【B7】______ how amazing some of Edison's inventions were.
In so many ways, Edison is the perfect example of an inventor, by which I 【B8】______ not just someone who 【B9】______ up clever gadgets, but someone whose products transform. the lives of millions. He possessed the key characteristics that an inventor needs to 【B10】______ a success of inventions. Sheer determination is certainly one of them. Edison famously tried thousands of materials while working 【B11】______a new type of battery, reacting to failure by cheerfully 【B12】______to his colleagues: 'Well, 【B13】______we know 8 000 things that don't work.' Knowing when to take no 【B14】______ of experts is also important. Edison's proposal for electric lighting circuitry was 【B15】______ with total disbelief by eminent scientists, until he lit up whole streets with his lights.
【B1】______
A．turned out
B．came off
C．went out
D．put off
The analysis phase answers the questions of who will use the system, what the system will do, and where and when it will be used.

Questions （1）to（5） are based on the following passage:
What makes a person a scientist？ Does he have ways ---or tools ---of learning that are different from those of others？ The answer is no. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power saw is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further: he must be sure that he has a reasonable answer to his question and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works
The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the condition permit. What works under one set of conditions at one time mustwork under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of his mathematics was latter tested through investigation. Einstein’s ideas were shown to be correct. A scientist uses many tools for measurement. Then the measurements are used to make mathematical calculations that may test his investigations.
（1）A sound scientific theory should be one that .
A) works under one set of conditions at one time and also works under the same conditions at other times
B) leaves no room for improvement
C) does not allow any change even under different conditions
D) can be used for many purposes
（2）What, according to the passage, makes a scientist？
A) The tools he uses.
B) His ways of learning.
C) The way he uses his tools.
D) The various tools he uses.
（3） Albert Einstein built up his theory of relativity through .
A) investigation
B) experiments
C) tests
D) mathematics
（4）“…Knowing how to investigate, how to discover information, is important to everyone.” The author says this to show .
A) the importance of information
B) the importance of thinking
C) the difference between scientists and ordinary people
D) the difference between carpenters and ordinary people
（5） What is the main idea of the passage？
A) Scientists are different from ordinary people.
B) The theory of relativity.
C) Exactness is the core of science.
D) Exactness and way of using tools are the key to the making of a scientist.
试题（71）～（75）
The software architecture is a set of software components, subsystems, relationships, interactions, the properties of each of these elements, and the set of guiding principles that together constitute the fundamental properties and constraints of a software system or set of systems. （71） defines a general set of element types and their interactions. The examples include Pipes and Filters, Model-View-Controller, and Reflection. A （72） in software architecture is a representation used to understand or document one or more aspects of a problem or solution. Architecture is usually used in conjunction with many adjunct terms. The （73） defines the key strategies, organization, goals and related processes of the enterprise. At the enterprise level, the （74） may be more of a set of guidelines on how the various software architectures should be constructed consistently across the enterprise. The （75）, which describes the high-level set of elements involved in application from a particular domain along with their interactions, is often used to focus on subsystem definition rather than application process level definition.
