Answer
Va rog mult de tot ! Ofer 45 de puncte... 1. Why does Annie decide to go to Montana? 2. How does Grace behave when comes to the house? 3. What does she think about her mother's idea 4. On what condition does Tom agree to Help Pilgrim? Repede va rog, dau coroana!!! TEXTUL: Annie and Robert McClean live in New York. They have a thirteen-year-old daughter, Grace. Grace has a riding accident in which she and her beloved horse, Pilgrim, are seriously injured. When neither Grace nor Pilgrim is able to recover from the accident, Annie asks the help of Tom Booker, a man who cures troubled horses and who lives on a ranch in Montana, USA. When Tom comes to see Pilgrim, he says that the horse is extremely damaged for him to help. However, Annie still feels that Grace will only get better if her horse recovers. She takes them both across America to Montana, where she contacts Tom, who very reluctantly agrees to look at the horse again. Tom could hear Pilgrim kicking the door of the old stable. The horse looked worse than he remembered. How could he even stand when his front leg was so thin? But here he was, kicking like a wild animal. Tom drove from the stable to Annie’s house and pushed the bell. He was surprised at the horrid face of the girl who answered the door. As Tom followed Grace into the sitting room, he noticed her leg and stick. The television was on and Grace sat down in front of it. Tom knew that she wanted him to feel unwelcome. « Listen, » she muttered. « I don’t know if she’s told you but I don’t want to know anything about this. It was all her idea. I think it is crazy and weird. They should just let Pilgrim die. » At that point, Annie came in from the hall. « Well, » Tom said in a nervous tone, « he is in a bad state. » He didn’t know how he was going to tell her the bad news. Then over her shoulder, he saw Grace. She didn’t seem upset, though she was trying to look uninterested. Suddenly it became clear how the three of them – the mother, the daughter and the horse – were all joined in suffering. If he could help the horse, perhaps he could help them all. He had worked it all out. He heard himself saying, « Perhaps we could do something. » Annie’s eyes shone with hope. « I said perhaps, but I need to know something first. It is a question for Grace. » Grace looked at him. « I can only help a horse if the owner is there. I am still not sure I can do anything with old Pilgrim. But I’ll try if you help me. Do you have a problem with that, Grace? » There was no answer from Grace. She left the room. Tom turned to Annie. « Right, I have to go now. » « Wait! What does she have to do? » « Just be there. Help me. » He was on his way out when he saw Grace standing in the doorway of the sitting room. She said something softly without looking at him. «I'm sorry? What was that?» «I said OK. I'll do it.»

Toamna tarzie isi ingramadea norii negri si miscatori deasupra muntelui.Dupa doua zile petrecute la cabana, coboram de pe creasta ca sa luam trenul spre casa .Era liniste.Deodata,Ioana ,sora mea mai mica, a scos un strigat cumplit.Ne-a aratat ingrozit culmea din fata, unde, pe doua cercuri aurii, se plimbau omuleti strani, pe care-i inconjurau niste miscarii geometrice. -Asi vrea sa-ti pot raspunde. -Ce ar putea fi ? Până să înțeleg ce fenomen producea neobișnuita priveliște , omuleții s-au adunat , s-au îmbrățișat și au fost acoperiți de cercurile galbene ,care au dispărut apoi cu mare viteză. Delimitati frazele si aratai felul lor adica P1=PP sau PS ?
