Write ONE WORD for each blank on the Answer Sheet.

Science and engineering have varied meanings and different ways in which they can be understood, though the differences are not easy to tell.

First is science. This is nothing but the use of reasoning to know how things work and what causes the happenings.

Engineering is about the way some tools, machines, systems etc are made with the help of human resources, raw materials and some scientific techniques. Science is important for engineering. Engineering can’t be done without knowing the basic principles of the working of the device that one wants to make. For example, if one wants to make a fan and they do not know how a fan works, then it is practically impossible for them to do so. Thus knowing how the fan works is science and making a fan is engineering.

Then comes the most important factor, the technology. Technology is always evolving with the help of the existing science and engineering techniques. It has to satisfy the usage of it by the consumers and safety of the people. For example, science will tell people the rules or the working of the equipment, engineering techniques will tell them how the equipment is made and the technology will consider both the above factors to create the same equipment but in a different way or using a different technique with some alterations(改变) giving birth to newfound technology. Thus again, science and engineering are important for technology to take place and the people who undertake the activities of science and technology are considered technologists.

All these three above discussed factors are important when one undertakes some kind of research work.

Some people think that technology is nothing but the way science is applied. If they make good investment in the field of science, then they would gain a lot from new technology. Thus, people start investing in many new ventures(项目)。

So we can see clear differences between science, technology and engineering. New technology is the best way to take a country to a higher economic position and to the path of fast growth. Technology requires the use of science and engineering as this is the best way to start and put the use of them into practice.

Title: Clear the doubts about technology

An old woman had two large pots, one on each end of a pole. She carried the pole with the pots across her neck.

One of the pots had a crack in it while the other pot was perfect and always delivered a full pot of water. At the end of the long walk from the well to the house, the cracked pot arrived only half-full.

For two years this happened daily, with the woman bringing home only one and a half pots of water. Of course, the perfect pot was proud. But the poor cracked pot was ashamed of its own imperfection.

One day, the cracked pot spoke to the woman by the well: “I am ashamed of myself because this crack in my side causes water to leak out all the way back to your house.”

The old woman smiled: “Did you notice that there are flowers on your side of the path, but not on the other pot’s side? That’s because I have always known about your crack, so I planted flower seeds on your side of the path. And every day while we walk back, you water them.”

“For two years I have been able to pick these beautiful flowers to decorate the table. Without you being just the way you are, I would not have this beauty.”
