Phrasal verb?
It beats me. My friend wrote me a letter with a line like this:\"... so I can LAUNCH OFF a search exercise....\"
Should that be \"launch out\"? But not \"launch off\"? If there is such
a phrasal verb, what's the meaning and usage or it's just purely a
mistake?
Thanks. http://www.google.cn/search?client=aff-os-maxthon&forid=1&ie=utf-8&oe=UTF-8&hl=zh-CN&q=launch+off
应该有这种用法的
