下一个 日 when Wilson goes to work, House asks his friend to cover him because he has to go to his place to finish some things for the 圣诞节 party. Cuddy doesn't suspect anything at all, and that's good because it is a great surprise from House. Greg is changing a bit for her. He wants to do things to make her happy. This party is a nice gesture of him, it was all his idea, and Wilson is sure she’ll like it.

Cuddy spends the whole morning working, in meetings and looking for House. Wilson has told her that Greg is in a patient’s house and he’ll come back later. She goes back to her...

When Lisa gets home, goes to her dorm and sits on the edge of the bed. Greg gets there some 分钟 later. ‘Anybody here?’
‘I’m here.’
He goes to her dorm. ‘How did it go?’
‘Very well thanks. Where have 你 been?’ 答案 Lisa selfconfident and trying to avoid 问题 about her date.
‘Out there...’
‘Yeah, I guessed that when I didn’t find 你 here.’
‘Smart girl. And that guy... did 你 like him?’
“No, I think I like YOU!” thinks Lisa. ‘Yes, sure. He's handsome, nice, interesting... a good guy.’
‘Good... well, I'll go to read a little...’ House goes to his...

House and Cuddy get to the hotel. ‘Here we are.’
‘Wow! Have 你 ever been here?’
‘Well, a few days...’
She didn’t need to ask more, she knew it was with Stacy. ‘Well, okay... we go in?’
‘Sure.’
They go in and approach to the receptionist, who is typing on the computer. ‘Good evening, we’d like to book a double room.’
‘Sure. Could 你 tell me your name, please? And how many days do 你 want to book the room?’
‘Gregory House. Days...’ He looks at Lisa. ‘How many days do we have?’
‘Hmmm I-I don’t know, we could stay here about four nights.’
House nods and turns...

Les alcanes sont des hydrocarbures saturés. C’est-à-dire qu'ils ne sont constitués que d'atomes de carbone (C) et d'hydrogène (H). Les alcanes se différencient des hydrocarbures insaturés (les alcènes, les alcynes, et les composés aromatiques) par le fait que les atomes ne sont liés que par des liaisons simples, ce qui donne un nombre maximal d'atomes d'hydrogène (d'où le nom de "saturé"). Les alcanes non cycliques possèdent donc une formule brute de la forme CnH2n+2 où n est un entier naturel
