at the weekend, I love sleeping in. 周末的时候，我喜欢睡懒觉
on Saturdays I sometimes lie in till 11. 周六有时候我会赖到11点才起。
I can’t have a lie-in if I have an Ielts test to take, though. 要是周六要考雅思我就不能赖床了。
If I get home on Saturday night before my flatmates, I wait up until they arrive and we have a drink and a chat before going to bed.
move out/in 搬出去/进来 move in together Sam and I have always been good friends so when we both get jobs in Rio, we decided to move in together.
live on sth I earn just enough to live on.
live off While Sue was unemployed she had to live off her saving.
sleep over My daughter loves it when a school friend sleeps over. The kid had a sleepover. 小孩在外过夜。
