Dear Teachers,<br/><br/>1. I have to look good for the clients.<br/><br/>- What does this mean?<br/><br/>2. Tenement house.<br/><br/>- Are there any other words the same meaning as this word?<br/><br/>3. If I could sleep in 3 or 4 hours, I would get back my working spirit.<br/><br/>4. If you don't keep your mouth shut, I'll kick you out of my house.<br/><br/>- Are 3 & 4 natural?<br/><br/>Thanks very much to Teachers,<br/><br/> Stevenukd.
