Earthquakes are the shaking, rolling or sudden shock of the earth’s surface. Earthquakes happen along "fault lines" in the earth’s crust. Earthquakes can be felt over large areas although they usually last less than one minute. Earthquakes cannot be predicted -- although scientists are working on it!

Most of the time, you will notice an earthquake by the gentle shaking of the ground. You may notice hanging plants swaying or objects wobbling on shelves. Sometimes you may hear a low rumbling noise or feel a sharp jolt. A survivor of the 1906 earthquake in San Francisco said the sensation was like riding a bicycle down a long flight of stairs.

The intensity of an earthquake can be measured. One measurement is called the Richter scale. Earthquakes below 4.0 on the Richter scale usually do not cause damage, and earthquakes below 2.0 usually can’t be felt. Earthquakes over 5.0 on the scale can cause damage. A magnitude 6.0 earthquake is considered strong and a magnitude 7.0 is a major earthquake. The Northridge Earthquake, which hit Southern California in 1994, was magnitude 6.7.

Earthquakes are sometimes called temblors, quakes, shakers or seismic activity. The most important thing to remember during an earthquake is to DROP, COVER and HOLD ON. So remember to DROP to the floor and get under something for COVER and HOLD ON during the shaking.

Which statement about earthquakes is not correct?

A. Earthquakes are the result of the sudden shock of the earth’s surface.

B. Earthquakes usually can be felt because they can last for a long time.

C. There are usually some signs for people to notice an earthquake.

D. People can feel an earthquake over 6.0 because it is very strong.

A. was riding a bicycle                 B. was just climbing the stairs

C. The Northridge Earthquake in Southern California in 1994 caused severe damage.

Not long ago the movie 2012 came into screen. The people were threatened by those scenes of destroying flood, severe earthquake, terrifying hurricane and constructions representing human civilization being destroyed and even swallowed by disaster. Luckily, they are just the director’s imagination, but the present situation is not heading a positive direction, either.

Take my own experience in Alaska as an example. Once I took a trip to the glacier. Along the way there stood signposts marking the snow lines of different years. They started from the foot of the mountain, but it was at the top when I finally saw melting glaciers(融化的冰川). My heart ached seeing the beautiful blue ice melting at every second.

Sad but true, they are the effects of global warming and the result of our human impact. Furthermore, each year the rising sea level will kill 56 million people, and that's about the population of the en tire Italy. According to studies, if the temperature keeps on rising like this, by the year 2050, some islands and coastal cities including New York, Shanghai, Tokyo and Sydney will be drowned in water.

Our fortune is in our own hands. It depends on us to shape our future, to reduce future human impact and find ways to form a peaceful relationship with our environment. Therefore, it's time for actions to be taken right now. Contribute a little to energy saving by using more efficient light bulbs and less hot water. Let recycle become our habit by thinking twice before throwing something away. Let us take public transportation as our first choice when going to a certain place. It might cost more time for now, but it' s to the benefit of a permanent future. Take care of every tree and grass around us by watering them or simply just avoid destroying them.

In a word, small drops of water make a big ocean. The earth does not belong to us. On the contrary, we belong to the earth. Please bear in mind that the earth is our home. It is our responsibility to build a brighter and better future of our planet and prevent what happened in the movie 2012 from becoming reality.
