California has lost half its big trees since the 1930s, according to a study to be published Tuesday and climate change seems to be a major factor (因素).

The number of trees larger than two feet across has declined by 50 percent on more than 46 000 square miles of California forests, the new study finds. No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles. In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts of southern California the decline was nearly 75 percent.

Many factors contributed to the decline, said Patrick McIntyre, an ecologist who was the lead author of the study. Woodcutters targeted big trees. Housing development pushed into the woods. Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources (资源).

But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010, Meltyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development.

The loss of big trees was greatest in areas where trees had suffered the greatest water shortage. The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking into account such things as rainfall, air temperature, dampness of soil, and the timing of snowmelt (融雪) .

Since the 1930s, McIntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which reduces the water supply available to trees during the dry season.

12. What is the second paragraph mainly about?

A. The seriousness of big-tree loss in California.

B. The increasing variety of California big trees.

C. The distribution of big trees in California forests.

D. The influence of farming on big trees in California.

13. Which of the following is well-intentioned (出于好意的)but may be bad for big trees?

A. Ecological studies of forests.             B. Banning woodcutting.

C. Limiting housing development.           D. Fire control measures.

14.What is a major cause of the water shortage according to McIntyre?

A. Inadequate snowmelt.                    B. A longer dry season.

C. A warmer climate.                      D. Dampness of the air.

15.What can be a suitable title for the text?

A. California's Forests: Where Have All the Big Trees Gone?

B. Cutting of Big Trees to Be Prohibited in California Soon

C. Why Are the Big Trees Important to California Forests?

D. Patrick McIntyre: Grow More Big Trees in California

B.

In 2021, Canadian glaciers (冰川) melted rapidly. In some parts of Asia, months' worth of rain fell in just a few hours. Europe saw severe flooding, and Madagascar faced a big drought. The world is going through a series of weather disasters caused by climate change.

Faced with these serious problems, from Oct. 31 to Nov. 12, the 26th United Nations Climate Change Conference of the Parties(缔约方) (COP 26) took place in Glasgow, UK. Global leaders from more than 190 countries came together, reviewing progress on their promises made since the 2015 Paris Agreement, and also discussing new steps to fight against the climate crisis(危机).

The main aim of COP 26 was to make sure that previous goals could be reached. They include achieving net zero (净零) carbon emissions（碳排放）globally by mid-century and keeping the global temperature increase below 2°C.

Net zero means that a country should take as much climate-changing gases out of the atmosphere as it puts in. China, for example, promised to peak carbon emissions before 2030 and reach net zero before 2060.

To reach these goals, all parties need to work together. At COP 26, developed countries agreed to raise $ 500 billion (about 3. 185 trillion yuan) over the next five years to help developing regions with climate change. More than 100 nations reached some agreements, one of which is to stop deforestation and restore the world's forests by 2030. Brazil has cut down huge amounts of the Amazon rainforest in recent years. The country also backed the deal.

16. What does the writer want to tell us by examples in Paragraph 1?

A. When weather disasters happen.

B. Climate problems are getting worse.

C. Where climate problems are most go serious.

D. Climate problems are different in different places.

17. According to the article, what's the main goal of COP 26?

A. To change the Paris Agreement.

B. To share technology for reaching net zero.

C. To make sure earlier goals will be be achieved.

D. To choose a new leader for the organization.

18. What might the writer suggest doing to deal with weather disasters?

A. The developed countries should set more five-year plans.

B. All developing regions should depend on developed countries.

C. All countries should stop making money at the cost of global climate.

D. The world needs to make a joint effort to fight against the climate change.

19. Where can we most probably read this article?

A. In a newspaper.   B. In a novel.   C. In a guidebook.     D. In a poster.
