Путь будет общий s=vt; s=18000м=18км, а время экспресс поезда можно рассчитать уже зная его путь t=s/v; t=900c

Convert into indirect speech. 1. Swindon: Who arrested this man? Sergeant: I did, sir. I found him in the minister's house, sitting at tea, with the lady with his coat off, quite at home. If he isn't married to her, he ought to be. 2. "I beg your pardon, Sir," said Mr. Pickwick [to the young man], "and I am very sorry to disturb the other gentlemen, too, but I come on very particular business." 3. "Good-bye, Lilian," he said to his wife, pleasantly, kindly. "I'll be coming out to attend some of these court proceedings." To his sister he said: "Good-bye, Anna. Don't let the others get too down-hearted." 4. "You wouldn't," he said, "like to leave a message, Miss, or write a note?" "Thank you, no." He stood a moment, looking at her as if debating whether she was armed. "Miss Tasburgh?" he said. "Tasborough," answered Jean. "Lord Saxenden knows me," and raised her eyes. 5. "Monsieur," she asked, "do you speak French?" "Perfectly." "Then can you tell me where they take the tickets?" The young man shook his head. "No," said he, "I am a foreigner." The girl sighed. "But what is the matter, ma'moiselle?" 6. "There is no good in my going to see little Hans as long as the snow lasts," the Miller used to say to his wife, "for when people are in trouble they should be left alone, and not be bothered by visitors. That at least is my idea about friendship, and I am sure I am right. So I shall wait till the spring comes, and then I shall pay him a visit, and he will be able to give me a large basket of primroses, and that will make him so happy." "You are certainly very thought¬ful about others," answered the wife. 7. "Have you mended the hole in the roof yet, little Hans?" cried the Miller in a cheery voice. "It is quite mended," answered little Hans. "Oh!" said the Miller, "there is no work so delightful as the work one does for others." "It is certainly a great privilege to hear you talk," answered little Hans,... "But I am afraid I shall never have such beautiful ideas as you have." 8. "Dear little Hans," said the Miller, "would you mind carrying this sack of flour for me to market?" "Oh, I am so sorry", said Hans, "but I am really very busy today. I have got all my creepers to nail up, and all my flowers to water, and. all my grass to roll." 9. "Who is there?" cries the Doctor. "Little Hans, Doctor." "What do you want, little Hans?" "The Miller's son has fallen from a ladder, and has hurt himself, and the Miller wants you to come at once." 10. She [Caro] said, her eyes wild, but with no tears in them. "I don't know how I shall bear being alone. I don't know how I am to bear it." 11. "I'm coming to Drover all in good time," Bennett said. "There'll be petition to sign. Do you expect us to attack the prison?" 12. Drouet was on the corner waiting, in good spirits. "Hello, Carrie," he said... "Got here safe, did you? Well, we'll take a car." 13. "Minnie! What's the matter? Here, wake up," said Hanson, disturbed, and shaking her by the shoulder. "Wha-what's the matter?" said Min¬nie drowsily. "Wake up," he said, "and turn over. You're talking in your sleep." 14. Mrs. Volterra shook hands with Erik. "Hello," she said, "I'm very glad to know you at last." 15. Dinny took a cigarette, and, with a long puff, said: "You saw great Uncle Cuffs, didn't you, Uncle Adrian?" 16. She said quickly, trying to divert him: "I saw the Queen just now. Going into the cinema. Why does she wear hats like that?"

Исправьте речевые ошибки в предложениях. В нашем городе скверы и парки дислоцированы очень удачно. Езжай прямо по проспекту. А.С.Грибоедов был еще и автором шикарного вальса. Ляжь лицом к стене и постарайся заснуть. Благодаря пожару я лишился дома. Он упал навзничь и уткнулся лицом в землю. Отец пристально слушал мой рассказ. Памятник поражает нас своими причудливыми габаритами. Поэт испытывал сильную ностальгию по родине. Помещики присваивали львиную часть доходов крестьян. Не могла и не схотела Катерина жить в “темном царстве”. Оплачивайте поскорее за учебу.
