Hi,<br/><br/>Some transitive phrasal verbs allow their "particle" to be separated from them while some don't. <br/><br/><i>ex) "throw away"</i><br/><br/><i>A: Mark threw away the ball.(O)</i><br/><br/><i>B: Mark threw the ball away.(O)</i><br/><br/><i>ex) "come across"</i><br/><br/><i>A: I came across an interesting article last night.(O)</i><br/><br/><i>B: I came an interesting article across last night.(X)</i><br/><br/>Then, how about "<i>put on</i> (pounds/weight)"?<br/><br/><i>A: Amber put on 15 pounds in just 10 days(O)</i><br/><br/><i>B: Amber put 15 pounds on in just 10 days.(?)</i><br/><br/>Is 'B' correct or wrong?<br/><br/>I would appreciate an answer. Thanks.
