跟读心得日记：
1、A more plausible explanation is that people are having to move around for work and often end up living miles away from their family and friends.(C20 Test1 Par3第19句)
miles away, 可不是几公里以外，而是千里之外，表示很遥远的距离
而且miles away还有一个非常有趣的俗语意思，表示心不在焉，思想开小差。
最经常的表达是， Are you listening to me now? you seem miles away. 你的思想在开小差。
When we were watching that movie, his mind was miles away.
2. Unquestionably, the data on that is sound.(C20 Test1 Par3第28句)
Sound, 在这里不是声音的意思，而是可靠的，有效的意思
