Reggie Carrillo is an environmental activist who lives in the Southwestern U.S. city of Phoenix, Arizona. He recently said that climate change affects the temperatures of city neighborhoods. He wants to share his knowledge with his neighbors to cool his community.

In Phoenix, some neighborhoods do not have many trees and open spaces. Some reports say temperatures are as much as 7℃ higher than in other areas of Phoenix with more trees. Those parts of the city were built with mostly roads and buildings but not much green space. Summer temperatures in Phoenix can be dangerous. One day last summer, the high was over 46℃. In the last year, the heat caused over 300 deaths.

Carrillo has learned about the city’s history by joining the Urban Heat Leadership Academy that is run by groups trying to protect natural resources. They are working to add green space to parts of Phoenix that have not received attention. The academy holds classes through videos on Saturday mornings. It helps teach people like Carrillo about why their living areas are so hot. It also teaches them how to organize activities that will help cool things down. They also discuss air and water quality.

Carrillo is working with others who went to the Urban Heat Leadership Academy. They want to build a walking area that will be known as a “cool corridor”, a place that has local plants that can help reduce temperatures. He is also organizing events to talk to people and to learn what they want.

Curtis Merritt is planting trees in another part of Phoenix. He is another graduate of the academy, like Carrillo. Merritt said many people have trouble getting enough food each day. So he is planting fruit trees—apples, and oranges. “What’s great about this project is that I not only get to help cool down my neighborhood by teaching...,” said Merritt. “Someday with those trees I’ll be able to feed my neighbors, too.”

A People in Phoenix don’t want trees or open spaces.

B High temperatures cause over 300 deaths in 2022.

C Areas of Phoenix with more trees are hotter.

D Trees may be good for reducing the heat.

解析：选D。D细节理解题。根据第二段第二句“Some reports say temperatures are as much as 7℃ higher than in other areas of Phoenix with more trees.”可知，在凤凰城，一些地区没有很多树木和空地，这些地区的气温比凤凰城其他树木较多的地区高出7摄氏度，由此可见树木对降温可能有帮助。故选D。

2.What can Carrillo do at the Urban Heat Leadership Academy? ① Know the reason why their communities are so hot. ② Learn how to organize helpful activities to beat the heat. ③ Learn how to protect animals and plants in danger. ④ Know whether the air and water are clean in their communities.

A ①②③

B ①②④

C ②③④

D ①③④

解析：选B。B细节理解题。根据第三段最后几句的“It helps teach people like Carrillo about why their living areas are so hot. It also teaches them how to organize activities that will help cool things down. They also discuss air and water quality.”可知，这个课程可以帮助像Carrillo这样的人了解他们居住的地区为什么如此炎热，它还教他们如何组织有助于降温的活动，他们还讨论空气质量和水质。故选B。

3.What does Curtis Merritt think of planting trees?

A It reduces the noise pollution and improves the air quality.

B It provides home for some animals and makes them comfortable.

C It not only helps beat the heat but also helps stop hunger.

D It not only cools things down but also makes the city beautiful.

解析：选C。C细节理解题。根据最后一段最后两句“I not only get to help cool down my neighborhood”和“I’ll be able to feed my neighbors”可知，在Curtis的社区，许多人每天都难以获得足够的食物。他认为种果树不仅可以降温，还可以喂饱他的邻居。故选C。
