bring back 恢复；使想起；归还
not only ... but (also) ... 表示“不但……而且……”。本句中的not only位于句首，其后的主谓要部分倒装，即根据主语的人称和数以及时态的变化，将不同的助动词提到主语前，需要注意的是but (also)后面的主谓不用倒装。
? Not only did my aunt teach at school, but (also) she wrote articles for newspapers.
我阿姨不仅在学校教书而且还给报纸写稿。

Write a letter to the city mayor about the problems and your suggestions.
Dear Sir/ Madam,
Environmental problems are becoming more and more serious all over the world.
With the development of the society, there are too many cars on the streets in our city. Cars have made the air unhealthy for people to breathe. Black smoke and poisonous gas are given off by factories. Factories also put waste into the river. And wherever we go, we can find rubbish.
Now more and more people have realized these problems. I think that governments should close down the factories and develop laws to stop people from driving cars every day. I suggest everyone in this town should help to clean up the river and the streets. We should call on everyone in the town to throw rubbish in the dustbins.
I hope the problem will be solved in the near future and our home will become better and better.

写作一封书信，信中首先要介绍你所在城市存在有哪些环境问题，是谁造成的这些问题，然后提出解决这些环境问题的方法和措施。
Dear Mr. Mayor, Thanks for making some time to read this letter. I’m a native here. I think everyone in this city wants to have a bright and beautiful home. But there are some environmental problems in our city. The river used to be very clean, but now the river was dirty. Even the bottom of the river was full of rubbish. People are littering in the river, Factories are pouring rubbish into the river. The air has become really polluted around here. There are so many cars on the road these days. More and more people driving to work or school today. Factories that burn coal also pollute the air with a lot of black smoke. There is also too much rubbish and waste around our living places. People throw away rubbish like waste plastic in public places. This turns beautiful places into ugly places.
To cut down environmental pollution, I think we should develop laws to stop factories’ littering. We should take the bus or subway instead of driving. Never take wooden chopsticks or plastic forks when buying takeaway food, remember to throw rubbish in the cans and keep public places clean and beautiful for everyone. I suggest that everyone in this town should play a part in improving the environment. I believe that our actions can make a difference and lead to a better future!
Best wishes,
John
