急...英文ARTICLES (a,an,the)係咩用???(20點)

We use 'a' with singular nouns beginning with a consonant sound (b,c,d,f,g,h,j,k,l,m,n,p,q,r,s,t,v,w,x,y,z). It is used when we are talking about things in general. However, we use 'a' in words e.g. 'uniform , 'university because they begin with a consonant sound, though the first alphabet a vowel. We do not use it when there is a uncountable or plural nouns.
The use of 'an' is similar to the use of 'a', but it is used with singular nouns beginning with a vowel sound (a,e,i,o,u). However, we use 'an' in words e.g. 'hour because it begins with a vowel sound.
We use 'the' in the following conditions:
1. unique object e.g. the moon
2. object that we have mentioned for the second time.
3. musical instruments e.g. the piano
4. family names
