(2) used to?与?be used to的用法比较
·used to?意为“过去经常”，其中的?to?是不定式符号，后接动词原形。

例文赏析：
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
