Hi, could you help me with these doubts I have?<br/><br/>1) Someone wrote" The first day, I xxxxxx". Is it optional to add the preposition ON before??<br/><br/>2) " I would like to go on a horse ride" It does not sound correct to me. But is it?<br/><br/>3) "I would like to play some tennis". Is the word "some" correct in this sentence?<br/><br/>4) " I went to Oxford 3 days". I would add FOR three days. but is the original wrong?<br/><br/>5) "We got all wet". Is this correct? or should he write "We all got wet?"<br/><br/>Thank you.
