2 Read the text. Match sentences A-I with gaps 1–7 in the text. There are two extra sentences. My trip to Delhi Saturday After two flights, I finally arrived in Delhi.! It didn't take long, and I was soon driving through the streets to my small hotel. The owner was really kind and friendly. 2_ It was very clean and comfortable. I was really tired, so I read some of my tourist guide to India. Sunday I got up at about 8 o'clock and went down for breakfast. Afterwards, I went out into Delhi. I found a taxi and went to my first tourist spot: the Shri Lakshmi Narain Temple. 5_ Inside, I found a guide and learned a lot about the history of the beautiful building. After this, I went to Raj Ghat. This is the last resting place of Mahatma Gandhi. The gardens were very green and there were lots of trees, but the fountains were dry because of the heat. After this I was very tired and hot. 6 Later, when I felt better, I went for dinner at a restaurant. I had a dosa, which is a kind of pancake with curried potatoes and onions. Tomorrow, I'm going to visit Humayun's Tomb and the museum. I'm going to go to the markets and do some shopping too.? Then I'll probably catch a flight to Varanasi. It's a very famous historical place. I'll let you know what it's like! 4
