    While you are at the bookstore, you may be faced with a difficult decision: e-books or paper books? Each one has its advantages and disadvantages. Making the best decision depends on a number of factor (因素).

    An e-reader can carry a whole library wherever you go, which is great for travelers or those who always want a choice of reading material Although e-readers are convenient, high levels of screen brightness from an electronic device(电子设备) can cause eye problems. A study in the Information Science Research found that young people preferred e-readers, like smart phones or iPads. That's why most teenagers are short-sighted.

    Many book lovers still prefer paper books and value the feeling of them. Paper books are very well designed, they look and smell good, and they carry with them a more human touch. Avid (热衷的)readers prefer reading on paper. Perhaps this is their choice because paper books give them a sense of ownership. It is reported that reading on paper rather than an electronic screen is better for memory and focus. But paper books are heavy and they are not convenient to carry.

    Which is your decision, an e-book or a paper book?

    Saving water is an important part of going green. As water becomes less and is polluted (污染的) more, conservation (保护) becomes more and more important. If people keep wasting water, more water needs to be treated and cleaned. This process (过程) needs quite a lot of money.

    As it is said above, cutting down on water usage is one of the most important things you can do for your local environment. That is why more green families are going blue by conserving and harvesting water.

    It may seem like a big concept (概念), but going blue starts with small changes. Something as simple as turning off the tap when you brush your teeth can save a lot of water. Wash your fruits and vegetables in a bowl instead of under a tap to save even more. Make sure that the taps are fully turned off every time you step away.

    Another way of reducing water usage is reducing your dependence on the main water supply. Rainwater harvesting can meet a lot of your home's water needs. Collecting rainwater is a great way to keep your garden green without running the sprinkler (洒水器).
