A．产后第2天宫底平脐
B．产后1个月子宫恢复正常大小
C．产后宫底每天下降1～2cm
D．产后10天为血性恶露
E．产后14天宫底在耻骨联合上2cm
参考答案：C
解析：解 析：产后第1天宫底平脐是盆底肌肉恢复将子宫上托的结果，以后子宫底以每日1—2cm的速度下降，至产后～10天降至骨盆腔内，耻骨联合上不能触及，产后6周子宫恢复正常大小。血性恶露于正常产褥时仅持续3～4天。

| Do you have many friends in this busy and noisy world? I think you can give me your answer without thinking for a minute. Friendship is so important that no one can live if he has no friends. 1 is happy to have a good friend to talk, laugh, and do other things with. Everyone will feel 2 if he has no friends. Maybe you will say that sometimes friends quarrel (争吵) with each other, but it doesn't matter. That doesn't mean they no longer 3 each other. They will make up and become 4 again. If our friends go to another place, we will feel very 5 . We miss them very much, but we can 6 them and write to them. Maybe we will never see them again. And we can 7 new friends. It is surprising to find out 8 we like new friends when we get to know them. There is more good news for people who have friends. They live longer than people who have no friends or have few friends. Why? Perhaps because they are 9 . Being happy helps you keep healthy. If you know someone cares about you, you may take 10 care of yourself. Do you think so? | ||||
