北师版（2019）必修三Unit 8 Green Living 单元练习（含答案）

Unit 8 Green Living
一、阅读理解（本大题共4小题，共8.0分）
A
Kevin Randall, a teacher, who teaches biology at Grandville High School, runs the environmental club at the high school which has around 2,000 students. The club is known as the GHS Green Team, and it aims to raise awareness among students and teachers of sustainability(可持续性). It also works on projects to reduce the environmental footprint of the building itself.
One of the club's recent projects focused on reducing waste in the school cafeteria. Randall said their cafeteria supervisor told them that the school went through 54,000 plastic forks every year. The club applied for financial help, built recycling centers for the cafeteria and bought metal silverware.
And now every student uses a durable metal fork or spoon instead of disposables. "And that's just one way we're trying to capture the low-hanging fruit," Randall said.
The efforts of Randall and his students have earned Grandville High School the Michigan Green School certification from the state. In addition to their work reducing waste in the cafeteria, the GHS Green Team has also built a garden with flowers and vegetables on campus. Over the years, Randall and his students have also been working on raising money to install solar panels(太阳能电池板) on the roof of the high school.
Randall said he was inspired to take the lead on environmental issues for his school because he wanted his students to have someone to turn to in the building who understands what's at stake(有风险) when it comes to climate change.
"And I also felt like I needed to do more in my life for my own two children at home," Randall added. "They need to know that their dad is working as hard as he can to reduce the effects of climate change and to make sure that other students out there are learning about this just the way they are at home."

二、阅读七选五（本大题共5小题，共10.0分）
As you get older, you'll meet a wider range of people from different cultures. Culture is an idea that isn't easy to understand. People often use the term to refer to things like food, holidays, clothing and music. (1) Customs, beliefs and values are also part of your culture. So when meeting people from different backgrounds, you can sometimes find that there're huge differences in how you see the world.
(2) For example, when you meet people from a different culture, ask them about their lives. It is one of the best ways to understand the culture. But be polite about it and remember they don't owe you an answer, and might not want to give it—not everyone wants to explain everything about their culture.
Maybe you've recently met someone from a different culture you find interesting. (3) Get to know his/her families and see how their customs and traditions differ from yours. You might be surprised to find how culturally different two people living even in the same town can be! Read books by and about people who are different from you. Reading memoirs(回忆录), biographies and other nonfiction books is an obvious way to learn about a country or someone's life. (4) Like with books, you can also watch movies to learn more about a culture. What's more, keeping yourself in a different culture through travel is also an amazing way to understand another culture.
(5) So accept and respect the differences between yourself and your friends from different cultures—remember that what is a difference to you is just their normal life!
A. Make friends with him/her.
B. But it also goes much deeper than that.
C. Show respect for people from other cultures.
D. You may think you know a lot about a culture or place.
E. Differences between us are what makes life so interesting.
F. There are many ways to understand other people's cultures.
G. Also don't ignore novels that have been translated from other languages.
5. A. A B. B C. C D. D E. E F. F G. G
6. A. A B. B C. C D. D E. E F. F G. G
7. A. A B. B C. C D. D E. E F. F G. G
