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.

C. The world’s weather. D. The earth’s temperature.

Marie Curie was a Polish physicist and chemist who lived between 1867---1934.
Together with her husband, Pierre, she discovered two new elements (radium and polonium) and studied the x-rays. She found that the harmful properties of x-rays were able to kill tumors(肿瘤). By the end of World WarⅠ, Marie Curie was probably the most famous woman in the world. She had made a conscious decision, however, not to patent（申请专利）methods of processing radium or its medical applications.
Marie Curie was born on November 7, 1867, in Poland and died on July 4, 1934.
Her co-discovery with her husband Pierre Curie of the radioactive elements radium and polonium represents one of the best known stories in modern science for which they were recognized in 1901with the Nobel Prize in Physics. In 1911, Marie Curie was honored with a second Nobel Prize, this time in Chemistry, to honor her for successfully isolating pure radium and determining radium’s atomic weight.
As a child, Marie Curie amazed people with her great memory. She learned to read when she was only four years old. Her father was a professor of science and the instruments that he kept in a glass case fascinated Marie. She dreamed of becoming a scientist, but that would not be easy. Her family became very poor, and at the age of 18, Marie became a governess(家庭教师). In 1891, Marie attended the Sorbonne University in Paris where she met and married Pierre Curie, a well-known physicist.
Marie Curie contributed greatly to our understanding of radioactivity and the effects of x-rays. She received two Noble Prizes for her brilliant work, but died of leukemia, caused by her repeated exposure to radioactive material.

Do you enjoy reading? Do you read newspapers or magazines? Chances are, if you do any of these activities, your pre-school child is on his way to becoming a reader.
The process of learning to read is complex, and one of the most important things to know is that parents can help their children learn to read. As children have conversations with adults, they hear both new and familiar words and their vocabulary grows.
There are many opportunities for adults and children to talk together, such as when riding in the car or in a bus, doing housework like fixing dinner, or bathing and getting ready for bed. A major part of conversation is listening. When children talk, adults listen and respond. Then children listen and respond, and so the flow of conversation happens.
Have you watched you pre-school child pretend to read to his younger sisters or brothers? Have you read his favorite story over and over? These experiences tell children that reading is fun. And when things are fun and they are repeated, your child will see letters. He begins to connect them to familiar words, especially the letters that make up his name. A natural next step for him to take is to write the letters.
When children see parents make a grocery list, they want to use a pencil and paper to make their own list. To encourage these beginning writing activities, have pencils, markers, crayons and scrap paper within your children’s reach.
The more children get connected with talking, listening, reading and writing, the easier it is for them to become active readers. While you as a parent have a big influence on these early behaviors, it is important to remember that opportunities for literacy experiences happen when you and your child share in the basic routines（日常生活）of everyday life.
