以下是一些新闻报道的信息:

[A]. Science magazine published the study about orangutans(长臂无尾猩猩). The scientists collected evidence from years of observations in six areas on Borneo and Sumatra. The scientists found that the animals demonstrated a total of twenty-four signs of cultural activity. Several actions were demonstrated in some orangutan groups, but not others.

[B]. The Environmental Investigation Agency and Telapak released the report. Telapak is an environmental group based in Indonesia. The Environmental Investigation Agency operates in several countries. The two groups say Indonesia controls ten percent of the world's tropical rainforests.

[C]. Richard Sandor is the chairman of the C-C-X. He praised the companies forming the group for demonstrating leadership. He said they believe that an active way to deal with global warning helps everyone. The group said its members want to reduce costs they may face from future rules on greenhouse gas emissions. Trading credits may help businesses find the most effective methods to reduce pollution. Members also hope to improve their public image on environmental issues.

[D]. Their most detailed effort involved ninety-nine kinds of birds, insects and plants in North America and Europe. They found that the territory where these plants and animals live has moved north by an average of six kilometers every ten years. In Europe, some butterflies now live as much as one hundred kilometers to the north because of changes linked to higher temperatures.

[E]. The new report says many areas experienced unusual weather in two thousand and two. Most of Asia, for example, was warmer than usual. India had unusually high temperatures in April and May. The extremely hot weather caused hundreds of deaths. There also were extremely dry conditions across India. Parts of Africa experienced unusual heavy rains. Yet other areas in Africa had unusual dry weather.

[F]. Hydrogen(氢) is the most common element in the universe. Hydrogen is a colorless gas. On Earth, it is present in large amounts in natural gas, coal, plants and water. By weight, hydrogen produces the highest energy levels of any known fuel. When burned in an engine, hydrogen releases no harmful pollution into the environment. When powering a fuel cell, the only waste is water. However, hydrogen is difficult to store. It also burns easily.

小题1:A severe ocean storm hit South Korea in August. It set a new national record for rainfall. In central Europe, more than one hundred people died in flooding caused by heavy rainfall in September. The flooding also resulted in thousands of millions of dollars in property damage. Yet large parts of North and South America had extremely dry weather.

小题2:One member of the Chicago Climate Exchange is American Electric Power. It's the biggest owner of electric power producers in the United States. Company officials say they hope their company's membership will demonstrate the ability of the C-C-X to grow.

小题3:For example, members of some groups make a kissing noise by tightening their mouths and sucking in air. Some groups use leaves to clean themselves or protect their hands from sharp objects. The scientists found that some of the animals use sticks as tools to remove insects from holes in trees. Other orangutans use leaves to crush insects or gather water.

小题4:Professors Parmesan and Yohe used similar methods to examine one hundred and seventy-two kinds of wildlife. They examined the timing of events in the spring, such as the appearance of flowers and the reproduction of animals. They found that these events happened an average of two days earlier than normal every ten years.

小题5:They say illegal operations to remove trees are causing large areas of forest to disappear. Environmental Investigation Agency director Dave Currey says the illegal operations are completely out of control.
