Questions 1-3
根据以下材料，回答题目。
As technology continues to advance, more and more jobs are at risk of being automated. Some experts predict that by 2030, up to 800 million jobs worldwide could be taken over by machines. This has raised concerns about the future of employment and the impact it will have on our society.
One profession that many believe could be facing extinction is that of truck drivers. The rise of self-driving vehicles threatens to replace the need for human truck drivers, which could have a significant impact on the economy. In the United States alone, there are approximatel
y 3.5 million truck drivers, making it one of the most common occupations. If these jobs were to disappear, it would have a devastating effect on individuals and communities who rely on this type of work.
However, not everyone believes that automation will have such a negative impact. Some argue that while certain jobs may be replaced by machines, new jobs will also be created as a result of technological advancements. They believe that humans will always be needed to perform certain tasks that machines are incapable of doing. Additionally, they argue that automation will improve efficiency and productivity in many industries, which can lead to economic growth and job creation.
Overall, the impact of automation on employment is still uncertain. While it is possible that certain jobs may become obsolete, it is also possible that new jobs will arise as a result of technological advancements. The key is to properly manage the transition and ensure that workers are equipped with the skills necessary to adapt to the changing job market.

Passage 2
Questions 4-6
根据以下材料，回答题目。
Climate change is one of the most pressing issues facing our planet today. The increase in greenhouse gas emissions has led to rising global temperatures, melting ice caps, and more frequent extreme weather events. This has had devastating effects on ecosystems, wildlife, and human populations.
In order to mitigate the impact of climate change, many countries have pledged to reduce their greenhouse gas emissions. This involves transitioning to renewable sources of energy, such as solar and wind power, and implementing policies to promote energy efficiency. However, there are still many challenges to overcome.
One major challenge is the high cost of renewable energy technologies. While the prices of solar panels and wind turbines have decreased in recent years, they are still relatively expensive compared to traditional sources of energy, such as coal and natural gas. This makes it difficult for some countries, particularly those with limited resources, to invest in renewable energy infrastructure.
Another challenge is the reliance on fossil fuels in many industries. Despite efforts to transition to renewable energy, fossil fuels still dominate the global energy market. This is due to their low cost and high energy density. In order to effectively combat climate change, there needs to be a shift away from fossil fuels and towards cleaner alternatives.
Additionally, there is a lack of global cooperation and commitment to addressing climate ch
ange. While many countries have signed international agreements, such as the Paris Climate Agreement, there is still a need for stronger commitments and actions. The issue of climate change requires a collective effort, and without global cooperation, it will be difficult to achieve meaningful progress.
Question 4: What is one consequence of climate change?
M)Rising global temperatures.
N)Melting ice caps.
O)四级真题试卷电子版及答案More frequent extreme weather events.
P)All of the above.
Question 5: What is one major challenge in transitioning to renewable energy?
Q)The high cost of renewable energy technologies.
R)The reliance on fossil fuels in many industries.
S)The lack of global cooperation and commitment.
T)The devastating effects on ecosystems.
