Global warming is the process of earth’s atmosphere heating up. Over the last 100 years, the average temperature of earth’s atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth’s climate.

Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment are some of the reasons that the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.

The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, prevent heat energy from escaping back into space. In the past, the climate didn’t change much because nature produced just the right amount of greenhouse gases to deal with it.

Today, most scientists are pretty sure that the rising temperature can’t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.

The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.

Over the past last 100years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts.

When I was growing up, I had an old neighbor named Dr. Gibbs. He didn’t look like any doctor I’d ever known. He never yelled at us for playing in his yard. I remember him as someone who was a lot nicer than most of the adults in our community.

　　When Dr. Gibbs wasn’t saving lives, he was planting trees. His house sat on ten acres, and his life’s goal was to make it a forest.

　　The good doctor had some interesting theories concerning plant care and growth. He never watered his new trees, which flew in the face of conventional wisdom. Once I asked why. He said that watering plants spoiled them so that each successive tree generation would grow weaker and weaker. So you have to make things rough for them and weed out(淘汰) the weaker trees early on.

He talked about how watering trees made for shallow roots, and how trees that weren’t watered had to grow deep roots in search of moisture. I took him to mean that deep roots were to be treasured.

　　So he never watered his trees. He planted an oak and, instead of watering it every morning, he’d beat it with a rolled-up newspaper. Smack! Slap! Pow! I asked him why he did that, and he said it was to get the tree’s attention.

Dr. Gibbs passed away a couple of years after I left home. Every now and again, I walked by his house and looked at the trees that I’d watched him plant some twenty-five years ago. They’re extremely tall, big and robust since they have deep roots now. However, the trees in my garden trembled in a cold wind although I had watered them for several years.

It seems that adversity(逆境) and suffering benefit these trees in ways comfort and ease never could. I stood there deep in thought.

　　Every night before I go to bed, I check on my two sons. I stand over them and watch their little bodies, the rising and falling of life within. I often pray for them. Mostly I pray that their lives will be easy. But I think it’s time to change my prayer(祷词) because now I know my children are going to encounter hardship..

4. Which of the following may be the author’s best prayer for his two sons now ?

  B.I wish them nice fortune so that they can meet people like Dr. Gibbs in the future.

  C.I wish them deep roots into the earth since the rains fall and the winds blow often.

  D.I wish them great shades under the tree since the sunlight is always sharp and bitter.

Ever wondered how one person could save the planet from the effects of climate change?

A British-made computer game on trial release on Monday creates different ways of doing just that．

“Fate of the World”puts the Earth’s future in players’ hands, placing them in charge of an international environmental body which could save the world from the effects of rising greenhouse gas emissions（排放）or let it destroyed by more emissions．

    Through different scenes, players can explore options such as geoengineering（地球工程） and alternative energy sources to save the planet from rising temperatures, decreasing natural resources and a growing population over the next 200 years．

    An improved version of the game will be followed by a three-month feedback period from players, with final release due in February next year．

    Created by Oxford-based games developer Red Redemption, the game is different from other mainstream action games mainly by using data from real climate models and advice from scientists and economists．

“Science data is often inaccessible and we are trying to put players in a position of power and connected with the issues,” Gobion Rowlands, Red Redemption’s founder and chairman said．

This year, a series of apparent errors in climate science and the failure of UN talks to reach an international deal to cut greenhouse gas emissions appeared to weaken the public’s interest in climate change．

However, games centered on sustainability（持续性）and human rights have been growing in popularity and are welcomed by green groups as a way of raising awareness．

Using climate change as inspiration for entertainment shows the issue has affected global culture, which can only be a good thing．Friends of the Earth's head of climate Mike Childs said.“We need creative industries to work with these big issues as the results can be extremely powerful and can help us to understand what a sustainable future looks and feels like,”he added．

    D．It aims to affect the global culture．
