D
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.
68. What is mainly talked about in this passage?
A. The melting of glaciers. B. Global warming.
C. The world’s weather. D. The earth’s temperature.
69. What causes global warming according to scientists?
A. Human activities. B. The nature itself.
C. The earth’s atmosphere. D. New discoveries
70. How can greenhouse gases make the globe warm?
A. They keep heat in the atmosphere
B. They let the heat go out into space.
C. They release heat into the air.
D. They can make the other gases warm.
71. From the passage we can see that global warming will bring about _________.
A. the pollution in the atmosphere B. natural disasters
C. population pollution D. the rise of glaciers
第三部分: 阅读理解(共20小题；每小题2分，满分40分)。
阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项，并在答题卡上将该项涂黑。 A
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.
