fall down the well 中“down the well ”是不是介宾短语作副词表修饰down作介词,fal

fall down the well 中“down the well ”是不是介宾短语作副词表修饰down作介词,fall 动词作谓语
还是fall down 作谓语 the well 作宾语
go down into the well中go down作谓语,into the well介宾短语作副词表修饰
如果我的分析完全错误请解释一下以上两个短语的词性
well 是井的意思

第一个down表动作持续的状态,如go down the street.
第二个down表动作的方向,即向下.
这是我个人的见解,仅供参考.
你学习英语真用心.
再问： 那词性是什么呢？
再答： down 1 (doun) adv. 1. a. From a higher to a lower place or position: hiked down from the peak. b. Toward, to, or on the ground, floor, or bottom: tripped and fell down. 2. In or into a sitting, kneeling, or reclining position: knelt down; lying down. 3. Toward or in the south; southward: flew down to Florida. 4. a. Away from a place considered central or a center of activity, such as a city or town: down on the farm; sent down to work at the firm's regional office. b. Away from the present place. 5. To a specific location or source: tracking a rumor down. 6. Toward or at a low or lower point on a scale: from the biggest down to the smallest. 7. a. To or in a quiescent or subdued state: calmed down. b. In or into an inactive or inoperative state: The generators went down at midnight. 8. To or at a lower intensity. 9. To or into a lower or inferior condition, as of subjection, defeat, or disgrace. 10. To an extreme degree; heavily: worn down by worry. 11. Seriously or vigorously: get down to the project at hand. 12. From earlier times or people: tradition handed down from one generation to the next. 13. To a reduced or concentrated form: pared the term paper down to five pages. 14. In writing; on paper: wrote the statement down. 15. In partial payment at the time of purchase: put ten dollars down on the necklace. 16. Into or toward a secure position: nailed down the boards; bolted the furniture down. prep. 1. In a descending direction along, upon, into, or through: rolled down the hill; floating down the river; went down cellar. 2. Along the course of: walking down the street. 3. In or at: The cans are stored down cellar. 我认为两个均为介词。 prep. 1. In a descending direction along, upon, into, or through: rolled down the hill; floating down the river; went down cellar. 这里提到后面可以接into，符合你所举的第二种情况。 2. Along the course of: walking down the street. 这是第一种情况。
