halfway的含义和句子结构
A：How can I find the direction using my own watch?
B: Imagine a line which runs from the center of the watch through a point halfway between the hour-hand and number one.This line will surely point south.
问题：
1. run from怎么翻译，是固定短语吗？
2. through a point 能改成 cross 吗？
3. halfway 这句怎么翻译？什么词性? halfway 做什么句子成分？
4. 能把 Imagine a line which runs from the center of the watch through a point halfway between the hour-hand and number one. 句子成分划分一下吗？后面定语从句内部根本读不明白。
非常感谢老师的帮忙！

【参考译文】
A: 如何使用(我的)手表来判定方向呢？
B: 假想有条直线从手表中心起始，穿过时针与数字1间的中间点，那么该直线就指向正南方向。
（注：运用此方法确定方向时，时针要对准太阳）
【参考解析】
1. run这里的完整搭配为run from point A through point B 穿过AB两点的直线，属于一般的常见搭配吧。也可以这样表达：run through points A & B.这同时也回答了您第2个问题，这种搭配通常through没见过被across替代的例子。
2. Half这里为副词，意思为【在…中间】，at an equal distance between two points,这里与between介短一起作point的定语。例;
It’s about halfway between London and Bristol.它大约位于伦敦和布里斯托尔的正中间。
3. Imagine a line which runs from the center of the watch through a point
halfway between the hour-hand and number one.
这是一个祈使句，主语省略；imagine为谓语；a line为宾语；which分句为定从。
