I should thank the development of science and technology.As we all konw,science brings us convenience and comfort.For example,by using washing machines,we can change our clothes to keep ourself comfortable and clean,without it we have to wash the dirty clothes by hand,so that we won't change and wash our clothes every day,we will enjoy neither comfort nor neatness.
