What's difference between these two sentences?

In the second sentence it involves a senior officer (this is not specified in the first sentence) and he/she did not stop the man himself/herself. The senior officer issued an order that the man was to be stopped by another customs officer.

to have something done (rather than to do it yourself) is simply to arrange for it to be done by someone else.  For example, you can wash your own clothes or have your clothes washed (by someone else).  You can pull a tooth, or have a tooth pulled (by a dentist).  You can make your bed or have your bed made (by a maid).

Hi,

what is the difference between these two sentences:

i'll look foward to seeing you in class again...

i look foward to seeing you in class again...

In terms of grammar, #1 means the 'looking forward' will happen in the future, while #2 means it happens in the present.

However, in terms of meaning in everyday conversation there is really no difference. You can interchange these.

You seem to be interested in tenses but not in capital letters.

Best wishes, Clive
