By “luxury(奢侈品)”, we mean "a pleasant and often expensive thing that is not necessary". From a historical point of view, things which were a luxury when they first came into being all became necessities later.
Anything, no matter luxurious it is, will become a necessity, when it is widely used. This is true of many of the present luxuries, among which mobile phones, cars, computers and many other things
(include). It is known to all that the purpose of the development of science is
(make) things easy for the mankind, not for only
small number of people.
, the first thing to do after a new invention occurs is to spread it so as to benefit
many people as possible. In the course of the spread, the luxury becomes decreasingly luxurious until
the end it becomes a necessity. This is an objective law, and
can be an exception.
With the quick (develop) of science and technology, the process for many things to become a necessity from a luxury will be greatly shortened. Anything that can be imagined will be invented and in no time becomes a necessity
(access) to ordinary people.

(shock) to see so much leftover food thrown away by students. What a waste! Concerned about it, my classmates and I had a

any leftover. Food was saved and the dining hall was cleaner.
