解释一下2,3

Answer 1

1 It is time for us to do.=It is time for going.
it is time for sb.to do sth. for 后接名词或动名词
2 Jim has no brothers or sisters. 否定句中的连词用or而不能用and
3 Isn't the dophin cute? Yes, it is. It can play the ball well.
海豚不可爱吗？不，它很可爱，它球玩得很好。
反意疑问句中，yes和no在否定前面句子的意思时候，它们的意思相反。如上面的句子中yes，结合后面的它球玩得很好否定前面的“海豚不可爱”，然后的it is 又对后面的句子的肯定。
4 It is time to do sth.
eg. It is time to go to bed.
