Hi,<br/><br/><br/><br/>Are the following sentences natural to a native ear?<br/><br/><br/><br/>1. Did you put that channel on? (I was asking who put on a particular TV channel?)<br/><br/><br/><br/>2. I have been working with them <u>for last week</u>. (I am not sure if ‘for last week’ sounds natural)<br/><br/><br/><br/>3. It was <u>only on</u> Monday, three days after the incident, that <u>the </u>police broke the news to media.<br/><br/><br/><br/>Thanks,<br/><br/>MG.
