halfway的含义和句子结构

问题描述

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。
