During initial days of computing, software was largely developed by small groups of people. When this software was to be maintained by another set of people, it used to be a nightmarish experience. When large commercial projects were to be handled, it used to be analmost impossible task to keep the time and budget under control, and projects used to get delayed and many projects were abandoned halfway. There was no systematic procedure forthe software development; everything was done on ad hoc basis. This ad hoc approach led tothe 'software crisis'.

Over the last few decades there has been a tremendous growth in information technologyand its impact on everyday life. Complex software systems have become critical to theoperation of many systems in areas such as banking, communications, manufacturing,power generation, and transportation. Progress in computer science and accumulated experience with industrial production of software have led to the emergence of software engineering as a separate discipline. The software engineering discipline has been defined as"the application of systematic, disciplined, quantifiable approaches to the development,operation, and maintenance of software. " that is, the application of engineering to software .

The computer science discipline concerns with developing large applications. Software engineering covers not only the technical aspects of building software systems, but also management issues, such as directing programming teams, scheduling, and budgeting.

For developing a software product, the development process is divided into differentstages. A convenient way of splitting the whole process is to divide the development into thefollowing five stages:

Requirements Analysis & Specification: define the system requirements in detail

Design: specify system architecture and modules in detail

Coding: produce source code

Testing: deal with unit testing and system testing

Maintenance: fix bugs, enhance features and adapt across platforms.

{二)Tell whether the following statements are true (T ) or false (F) according to the passage A.

第1题

Fifty volunteers were alphabetically divided into two equal groups. Group A to participate

in a 7-week exercise program, and Group B to avoid deliberate exercise of any sort during those 7 weeks. On the day before the exercise program began, all 50 men participated in a step-test. This consisted of stepping up and down on a 16-inch bench at 30 steps a minute for 5 minutes. One minute after completion of the step-test, a pulse rate of each subject was taken and recorded. This served as the pretest for the experiment. For the next 7 weeks, subjects in the experimental group (Group A) rode an exercycle for 15 minutes each day. The exercise schedule called for riders to ride relaxed during the first day's ride, merely holding on to the handle bars and foot pedals as the machine moved. Then, for the next 3 days, they rode relaxed for 50 seconds of each minute, and pushed, pulled, and pedaled actively for 10 seconds of each minute. The ration of active riding was increased every few days, so that by the third week it was haft of each minute, and by the seventh week the riders were performing 15 solid minutes of active riding.

At the end of the 7 weeks, the step-test was again given to both groups of subjects, and their pulses taken. The post exercise pulse rates of subjects in the experimental group were found to have decreased an average of 30 heart beats per minute, with the lowest decrease of 28 and the highest decrease of 46. The pulse rates of subjects in the control group (Group B) remained the same or changed no more than 4 beats, with an average difference between the initial and final tests of zero.

How many people were in each group？

A．100.

B．25.

C．50.

D．15.
