Carol is very 4 to have a little sister. So she is always talking about her to Susan. At first she is very 5 in the new baby because she doesn't have any brothers or sisters. But 6 some time she begins to get tired of Carol's endless talking(喋喋不休的谈论) about it. She also feels a little jealous(嫉妒) of her friend. One morning when the two girls 7 7 in the school ground, Carol says to Susan , " Do you 8 , Sue , my ba- by sister has put on nearly half a pound in weight(体重增加了半磅) this week.
