ПОМОГИТЕ ПОЖАЛУЙСТА С АРТИКЛЯМИ (the,a,an,-)

I. Margaret was talking to the Osbaldistons. 2. In dim light streaming down the stairs from behind her, he scarcely recognised the Lily he had known. 3. The barbaric Bertie got no hint whatever that he was barbaric. 4. The father and daughter appeared at last. 5. Gradman is here, darling, and  mother, and Aunt Winifred, and Kit and Michael. Is there anyone you would like to see? 6. Louis seemed rather grave, still, retiring man, but the Caroline of this evening, which was not the Caroline of every day, thawed his reserve. 7. She watched advent of Tasburghs almost maliciously. Hubert and young Tasburgh at once discovered mutual service in Mesopotamia. 8. My visit was specially made to the good Mrs. Ames. 9. Professor Beans is the man to whom you'll be responsible for your undergraduate teaching. 10. This Pat wasn't at all like the Pat of his memories. When she smiled he saw the Pat he had known, the Pat smiling at him from the worn photo that still lay in a pocketbook against his heart. But watching her, he grew aware that the family was divided in its attitude. Alice and Mrs. Baxter were partisans of a new Pat. He still felt that he couldn't bring the two Pats together; but he didn't hold that against the Pat of the present. 11. A flustered Clarice stood beside me. 12. If you are a Napoleon, you will play a game of power; if you're a Leonardo, you'll play for knowledge; the stakes hardly matter. 13. At that time I had the greatest admiration for Impressionists. I longed to possess a Sisley and a Degas, and I worshipped Manet. 14. The medical practitioner quite refused to accept unhappy Selina's theory. 15. He cared to say no more; he had thrown quite dust enough into honest Adam's eyes. 16. This was the famous Frank A. Cowperwood whom he had read about. 17.  A certain Joseph Zimmerman suggested that he undertake operating in street railway shares for him. 18. Elsie said she would ring up Doctor Worple. 19. Poor Edward muttered something, but what it was nobody knew. 20. The difference between the pair was that while the father was violent and bully,  the son had thrice the nerve and courage of the parent, and could not merely make an attack, but resist it; and finding that the moment was not come when the ­contest between him and his father was to be decided, he took his dinner with perfect coolness and appetite before the engagement began.  Old Osborne, on  the contrary, was nervous and drank much.
