Our environment isn't as green and beautiful as it should be. There are steeK钢铁)monsters blocking out the sun, blowing out dangerous smoke,and letting out poisonous chemicals into rivers,cars producing harmful waste gases,people throwing out waste in a wrong way,and all other kinds of sources that ruin the planet. Facing current environmen?tal problems, people need to do their best to save the earth.

You can see many big garbage dustbins in the streets. They're not there for a show,but for you to drop your waste. We should realize that what we do does count. So next time you get that urge to throw gum or a chocolate package out of the car window,or "accidentally" drop as you walk down the street,ask yourself how much waste you've been contributing to the environment with that bad habit going on for years.

At home,the first thing we can do to protect the environment is to avoid letting water run continuously and make sure that taps(水龙头)are not leaky (泄漏的), which would help greatly in scrimping. Another is to use energy-saving lights,and turn them off before you leave the rooms. It not only saves energy, but also cuts down electricity costs.

Recycling is a method to make items reusable. Many things you want to throw out can be made into new products through the reproducing process. Use your imag?ination to come up with ways on things that you can use again.

Pass on the message of simple ways to save the environment to kids. Starting with kids is a good way of teaching the message early in their lives,in the hope that they can carry it forward as they grow older.

With environmental protection awareness(意识)in mind, we can do what we can,for the results are to have a big effect on the planet. As long as we do our part, the world is one small step closer to being saved.

Astronauts on shorter shuttle missions (使命)often work very long days. Tasks are scheduled so tightly that break time is often used to finish the day's work. This type of schedule is far too demanding for long missions on the International Space Station (ISS). ISS crew members usu?ally live in space for at least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on the earth as much as possible. Weekends give the crew valuable time to rest and do a few hours of housework. They can communicate with families and friends by e-mail, Internet phone and through private videoconferencing.

While astronauts cannot go to a baseball game or a movie in orbit, there are many familiar activities that they can still enjoy. Before a mission, the family and friends of each ISS crew member put together a collection of family photos?messa?ges ,videos and reading material for the astronaut to look at when he will be floating 370 kilometres above the earth. During their mission, astronauts also receive care packages with CDs, books, magazines, photos and letters. And from early 2010 , the Internet became available on the ISS,giving astronauts the chance to do some "web surfing(冲浪),,in their personal time. Besides relaxing with these more common en?tertainments ,astronauts can simply enjoy the experience of living in space.

Many astronauts say that one of the most relaxing things to do in space is to look out the window and stare at the universe and the earth. Both the shuttle and the ISS circle the planet several times each day, and every moment offers a new view of the earth's vast land mass and oceans.
