Carlos and I arrived in San Francisco last Wednesday night at 9:00. The next day, it rained, but the weather did not/didn't stop us from sightseeing. We carried our umbrellas and visited Fisherman's Wharf. Then the rain stopped, so we climbed Telegraph Hill. We walked around there a bit, and then we boarded a bus to Baker Beach. We watched the sun set next to the Golden Gate Bridge, and we listened to the ocean waves. I was so tired, I did not/didn'twant to stay out any longer. I wanted to go back to our hotel. On the way home, we decided to have dinner. Chinatown was the perfect spot. We ordered a "bird's nest" and red bean soup. It was delicious. Everything in San Francisco was amazing.
This whole paragraph has to be in past tense form, so we have to put "-ed" after the end of each regular verb. Additionally, to describe a verb which the subject hasn't done, you use "did not <verb>". DO NOT put -ed after the verb because you already have the past tense form of do: "did."

Reliance on open fires or traditional stoves can lead to deadly indoor air pollution. A lack of food, clean water and sanitation can also be fatal.</em>
