　　 With golden sunshine and a gentle breeze（微风）, autumn is the most beautiful seasons in the year. This is a great time to go outside and have fun. Go to a valley to see red maple trees,go and pick fruit in an orchard or find an open field to fly your kite in.

　　However, for many high school students, these great activities may be just a dream. With plenty of work to do, they spend all their hours indoors, struggling for a high mark in their exams. Of course, study is one of the most important things for teenagers. But life is definitely much more than that.

　　Sometimes we spend so much time studying that we forget how to make life wonderful. In doing so, we lose the real purpose of life -to be a valuable and happy person. To enjoy just how great it is to be alive, we have to put down our books and pens and look around us. Students, take some exercise to improve your health, talk with your parents and friends for understanding and walk around outside to refresh（振作）our body and mind.

　　Going out and enjoying the beautiful countryside often helps our creativity in our work. Chinese craftsman, Lu Ban created a saw to help woodworkers. But if he hadn't walked outside, he would not have been inspired by a kind of toothed（锯齿状的）grass. We could also suppose if Newton hadn't rested under that apple tree, then he wouldn't have been hit by an apple, and his classic（经典的）theories would not have come out.

　　Going out is not only a break from hard work, but a chance to add to life experience. So come on, give your brain a good rest. Step out of the books and get your bag ready for an autumn outing. We are sure you will get much more than knowledge from the exciting journey.

　　 Walk through the Amazon rainforest today and you will find it is steamy, warm, damp and thick. But if you had been around 15,000 years ago, during the last ice age, would it have been the same? For more than 30 years, scientists have been arguing about how rainforests like the Amazon might have reacted to the cold, dry climates of the ice ages, but until now, no one has reached a satisfying answer.

Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to slow global warming. Currently the trees in the Amazon take in around 500 million tons of CO2 each year: equal to the total amount of CO2 giving off in the UK each year. But how will the Amazon react to future climate change? If it gets drier, will it still survive and continue to draw down CO2 ?
