помогите редактору улучшить следующие тексты (обратите внимание, что в редактировании в первую очередь нуждаются подчёркнутые фрагменты):

1. Элизабет торопливо завершила туалет и, напоследок торопливо взглянув в зеркало, выключила в спальне свет и спустилась вниз. Из кухни доносились голоса. Когда раздался звонок, она пошла открывать, довольная представившейся возможностью самой встретить гостя. Дети могли сморозить какую-нибудь глупость, и ей потом придётся краснеть, а тот факт, что она наказала им вести себя наилучшим образом, ничего не менял.

Переведите грамотно текст:

Jim, a young car-driver, was a boarder at old Riddle’s. He was in love with Rosy, Mr Riddle’s only daughter, and Rosy was in love with him. They wanted to get mar ried; but Mr Riddle expected his daughter to marry a richer man, and that meant that Jim was going to have a hard struggle for his happiness.

Jim had a friend called Pilkins who worked as a night clerk at a chemist’s. One day Jim came to the chemist’s, looking very excited, and told him that he and Rosy had decided to run away and get married that night. “That is”, he added, “if she doesn’t change her mind. One day she says she will, and the same evening she says she won’t beca use she’s afraid. But you can help me, can’t you?” Jim asked, finishing his story.

“I don’t see how?” said Pilkins.

“I say, Pilkins, isn’t there a drug that’ll make a girl like

you better if you give it to her? 1 think that if I have a real stuff like this to give Rosy when I see her at supper tonight, she won’t be afraid any longer. 1 don’t mind if I have to pay

for it even if it costs all the money I have.”

“When is all this supposed to take place?” asked Pilkins.

“At nine o’clock. Supper’s at seven, at eight Rosy goes to bed, pretending to have a headache, at nine I go under her window and — Make up the powder, Pilkins, will you? And I’ll look after everything else myself.”

“I’ll do my best,” said Pilkins.

He gave Jim a powder and received his heartiest thanks.

“This,” Pilkins said to himself, “will make Rosy sleep for several hours without any danger to her."

When Jim had gone, Pilkins, who was in love with Rosy too, immediately went to Mr Riddle and told the old man that Jim and Rosy were going to run away that night.

“Can I do anything for you, sir?” he asked politely. “Shall I call the police?”

“No, thank you,” said Mr Riddle. “My room’s just above Rosy’s. I’ll go up myself after supper and take my gun and wait. If he comes under Rosy’s window, he’ll want a doctor, not a policeman, you can be sure of that.”

Pilkins went home. All night he waited for news of the tragedy, but none came. At eight o’clock in the morning when it was the day-clerk’s turn to start work, Pilkins went hurriedly to Mr Riddle’s, As he was crossing the street he was surprised to see Jim, who cried out: “Rosy and I were married at 9.30 last night. She’s up at the flat making lunch — Lord! I am the luckiest man. You must come and have dinner with us some day.”

‘‘And the ... powder?” Pilkins said in a weak voice.

“Oh, that stuff you gave me? Well, it was this way. I sat down next to the old man at supper last night. I looked at Rosy and said to myself, ‘Don’t play any tricks on thal girl. She loves you, that’s clear enough.’ Then I looked al her father and thought ‘There’s the man you should take care of.’ So I watched for my chance and put the powder in old Riddle’s coffee — see?”
