Question 4 is based on the news report you have just heard.

听力原文

        Two boys and four girls were born on Monday, to the surprise of a young couple and doctors who had expected five babies. This was the first record of six babies being born at the same time in that region. (3) [The doctors prepared from early in the morning to help deliver five tiny citizens. They were in the operating room with five teams of doctors, one for each baby.] The first five babies were delivered successfully, and all baby beds were occupied. And then all of a sudden, it turned out there was another waiting to come out. (4) [The doctor said the babies were in healthy condition, but could not go home immediately. They needed to stay in the hospital for two to three months for medical supervision.] The mother, who was in stable condition could return home a day later if all physical tests came back normal. The babies’ mother commented that they had already prepared room for five babies at home, so they will have to rearrange things for their happy surprise. The new parents have yet to name the sixth baby, but are considering either Lily or Rose.

4. What did the doctor say about the newborns?（关于新生儿，医生说了什么？）

解析：C。录音中间部分提到，医生说婴儿们需要在医院待两到三个月来接受医疗监护。C项与此内容相符，其中的needed to stay in the hospital原词复现，for a couple of months是对录音中for two to three months的同义替换，故C项正确。

错项排除：录音中虽然提到了physical tests，但没有明确说必须接受2到3次体检，故排除A项。录音中医生说六名婴儿都很健康，没有提到婴儿的体型大小，故B项排除。录音中医生说宝宝妈妈可以一天后回家，但婴儿要留院观察数月，故D项错误。
