1 . 听下面一段较长对话，回答以下小题。
1. What can we say about the weather on Sunday?

A．It was fine.

B．It was hot.

C．It was changeable.

2. What do the locals think of small balls of ice in midsummer?

A．It’s beyond their expectations.

B．It’s a common phenomenon.

C．It’s caused by climate change.

2 . Scientific reports show the destructive effects of climate change, but many scientists say it is important to remain positive. If the world continues to change, don’t give up, and we can still prevent some of the worst effects of climate change.

Recently, however, many scientists are dealing with the feeling of doom about climate change or “doomism.” Jacquelyn Gill is a climate scientist at the University of Maine. She says that around 2018 she noticed an increase in these “doomers,” or people who think that saving the earth is hopeless. They refuse to change their behavior or consider how they can work to prevent climate change.

The United Nation’s Intergovernmental Panel on Climate Change (IPCC) recently published its third report. This report explained the damage caused by the burning of traditional fuels, like oil and coal. New investments in traditional fuels and removal of forests for farming are preventing the world from helping stop climate change.

Anderson is the Environment Program Director for the United Nations. She says officials are trying to get people to take action because there is a climate crisis. Their goal is not to scare people into doing nothing.

“We are not doomed, but rapid action is absolutely essential. With every month or year that we delay action, climate change becomes more complex, expensive and difficult to overcome,” Andersen said.

The UN IPCC report stated that without fast and extreme measures to cut carbon pollution, the world is not likely to limit warming to 1.5 degrees Celsius. The global temperature has already increased by 1.1 degrees Celsius. After 1.5 degrees, climate change will quickly worsen causing environment to be in danger. It will cause an increase in weather disasters.

James Skea is a leader from the UN IPCC Report. “We don’t fall over the cliff at 1.5 degrees. Even if we were to go beyond 1.5, it doesn’t mean we throw up our hands in despair,” Skea said.

Michael Mann is a climate scientist at Pennsylvania State University. He says that scientists used to think Earth would continue to warm decades after we balance emissions. Balancing emissions to net zero means not creating more carbon in the atmosphere than oceans and forests can remove. New research suggests that it will only take a few years to decrease carbon levels in the air after we balance emissions.

1. What is the writer’s attitude towards climate change?

A．Optimistic.

B．Pessimistic.

C．Cautious.

D．Objective.

2. According to the passage, which is mentioned in the third report by UN IPCC?

A．The change of people’s behaviors.

B．The damage caused by human activities.

C．The sharp increase in number of doomers.

D．The measures to help stop climate change.

3. What is the main idea of the last paragraph?

A．The significance of UNIPCC third report.

B．The difficulties of decreasing carbon levels.

C．Scientists’ optimistic attitude towards climate change.

D．The need to take immediate actions against climate change.

We hear about climate change pretty much every day now. Scientists have just announced that July was the hottest month ever     1     (record). The scientists are from the National Oceanic and Atmospheric Administration (NOAA) in the USA. A spokesperson from NOAA said, “July is     2     (typical) the world’s warmest month of the year, but July 2021 beat     3     (it) as the hottest July and hottest month ever.” NOAA said Earth’s land and ocean surface temperature in July increased     4    0.93 degree Celsius,compared to the 20th-century average of 15.8 degrees Celsius. The Northern Hemisphere was 1.54 degrees Celsius hotter than average.

The NOAA spokesperson said this new record was     5     (worry). He said, “In this case, first place is the worst place to be.” The announcement from NOAA comes a week after a 4,000-page report on climate change from the United Nations. It clearly     6     (state) that humans had affected the climate. It wrote, “It is clear     7     human influence has warned the atmosphere, ocean and land.”     8     total of 234 scientists from 66 countries worked on the report. It warns that extreme weather     9     (continue) to get worse. It says every region will experience multiple     10    （change) in weather, like sweltering heat and flooding.

When we talk about climate change,we mean the unusual changes in the earth's weather patterns that     1     (happen)over the past 100 years.

It is true    2     the weather is always changing and sometimes the weather changes in ways we really don't expect. By     3     (record) the temperature of each day in many different parts of the world we can find the average global temperature. When all     4     (temperature)are taken together,we can expect ups and downs in the year to cancel each other out and the average temperature to stay roughly the same from one year to the next. However,scientists have found that the temperature is not constant and our planet is    5     (actual) getting warmer each year. This is called"global warming" and it is     6     major part of climate change.

Extreme changes in climate are nothing new on the earth. In     7     (it)long history,there have been times since the earth's average global temperature rose, causing ice     8     (melt)and sea levels to rise. At other times the earth has been very cold. These "ice ages"saw huge areas of the planet     9     (cover)with snow and ice. These might sound like extreme changes in the earth's climate,but they came out very gradually over thousands     10     years.

Global temperature changes are in fact a natural process. However, human demands for energy, manufactured goods, transport and animal products have increased carbon emissions (排放). We     1     (cause) over 1°C of warming since the 19th century. For comparison, it     2     (take) 5,000 years for the Earth to warm up by 4-7°C after ice ages.

The small numbers may seem insignificant,     3     this temperature increase has had a huge impact globally. Sea levels have risen 15cm in the past century. Animals and ecosystems can’t keep up with the new rate of change,            4     forces many species into extinction. In turn, this comes back to bother humans, who rely on a balance of all ecosystems     5     (keep) our way of life.

Unless we completely change our habits, our future could be     6     (hope). In face of climate change,     7     governments should be focusing on now is promoting the use of renewable energy, supporting green farming, and reducing population     8     (grow). Individuals can pay attention to     9     (cut) out car and plane travel, limiting their intake of animal products, and consuming far less manufactured goods. It will take much more than a village, but it’s possible — and everyone is responsible     10     what happens next.
