Срочно ,переведите пожалуйста!!!! 1. My parents were surprised to see me at home. I hadn't warned them about my visit but, naturally, they were glad to see me anyway.
2. By the evening it became clear that Jack and his friends were lost in the taiga. Unfortunately they hadn't told anybody about their camping route and the emergency workers didn't know where to search for them.
3. The people of the village could smell smoke but they didn't realize that they were in danger. For some reason the radio hadn't broadcast anything about the coming forest fire by the next morning,
4. The emergency workers did everything they could to save the people. They worried as the helicopter hadn't arrived yet and some people needed medical care urgently.
5. It was getting late and I was still far from home. I felt uneasy because I hadn't left a note for mum — she would worry a lot.
