同位语问题

This automobile is running at a speed of 70 miles an hour.这里是of 70 miles an hour作状语还是79 mils an hour作状语？

we have several things, namly, pears, apples and oranges. 这里namly只是一个引导词吗？并不作成分吗？

This automobile is running at a speed of 70 miles an hour.

of 70 miles an hour为介词短语作定语修饰a speed, 表示同位关系。at a speed of 70 miles an hour.这个介词短语作状语，修饰动词is running.

We have several things, namly, pears, apples and oranges.

namely为插入语，不参与句子成分划分。pears, apples and oranges是several things但同位语。namely可用破折号替换

We have several things — pears, apples and oranges.
