Example Input: Article: When people who are nature lovers worldwide wish all humans to realize the importance of their natural surroundings, many Australians are turning caring for the environment into a way of life. Julie, an Australian housewife in Brisbane is one such example. Even though autumn is approaching Australia's Brisbane in April, one can still watch colorful blooming flowers in Julie's little garden, as she tells that in her community,"Each of us has a beautiful yard. The whole community, from children to elderly people, takes care of the environment as if they are taking care of their own garden." "Gardening is the most popular club in our community," she says. "A lot of retired people don't just regularly organize gardening lectures, but also personally visit families in the community to provide gardening training. So you can see that flowers continue to blossom in our gardens throughout the year." Talking about her people's sense of caring for the environment, Julie says when people in the community take along their dog, they always carry a garbage bag to deal with the dog's waste. "In our community, you will never experience the embarrassment of stepping on the dirty waste while you are walking on the grass," says Julie with a smile. "Taking care of the dog's waste can also help to develop children's sense of responsibility!" As to protecting water resources, the Australian government has made strict rules for families. Julie says, "We certainly would not use tap water to water the flowers!" She says almost every family in her community has a huge tank used to store rainwater, which is later used as the resource of all outdoor water use, including car washing and watering the garden. This year, they also asked people to connect the water tank with their toilets.

Another word for criticism is appreciation.When I criticize or appreciate some objector another, I look for its good points and bad points.In reading any printed or written matter, I always have a pencil in hand and put any comments in the book or on a separate paper.In other words, I always talk back to the writer. That sort of critical reading might well be called creative reading because I am thinking along with the author, asking him questions, seeing whether he answers the questions and how well he answers them.I mark the good passages to store them in my memory piece of writing; where, how and why could or should I improve upon it? You might think that doing what I suggested is work.Yes, it is, but the work is a pleasure because I can feel my brain expanding, my emotion reacting and my way of living change. Reading exercises is a great influence on a person.If pictures, still or moving, accompany the reading, the memory will retain the material for a long time. Just as evil books can corrupt, so also can good books gradually work a change on a corrupt person. Let's get back to the beneficial effects of thinking while reading.It helps us to enlarge our minds.We understand more about the universe, its people and many of its wonders.We learn to think and observe in new ways.We certainly do get a feeling for the language we are reading.All good writers in any language have been readers who read critically and continuously.
