Discuss: 20-mile-trip

來源: 於 2015-07-11 11:52:47 [博客] [舊帖] [給我悄悄話] 本文已被閱讀：次

Please advise for the following:

1: Can "20-mile-trip" be used as a noun combination? or is it supposed to be "20-mile trip"?
2. I also do not like the expression "hang down", but was unable to find a more accurate "expression". Any suggestions?

The typos have been corrected.

Thanks.
