Essay on the Types of Germs - bacteria [22]
Do not cry! Just take it step by step, and your writing will improve.
I notice that not much time elapsed between when you got the feedback and when you reposted the essay. That was not enough time to review your English learning materials for the rules about articles and plurals and then go sentence by sentence carefully.
So, I am continuing to think that one problem is that you are in too much of a hurry!
What you need to do -- just on the problem of plurals -- is to go through each sentence, looking at each noun and asking whether you have properly used the singular or plural form. If the noun is the subject of a sentence, then you must also check to make sure that the verb matches the noun -- singular noun with singular verb, plural noun with plural verb.
After doing that, you can start to think about punctuation, again reviewing your learning materials before going through your essay sentence by sentence.
So, for example, if you did that and then considered this sentence:
It is, consist of single cell and its tiny usually cannot see it without using a microscope.
you would see that the verb does not match the noun -- "it" is singular, "consist" is plural -- and you also have an extra verb in there. Is "it" proper? Yes, if it refers to a single protozoan parasite. Hmm... just to be sure your reader does not misunderstand, why not say "protozoan parasite" instead of "it"?
So, then you would have:
A protozoan parasiteis consist
s of single cell and its tiny usually cannot see it without using a microscope.
It is not correct yet! I said you should review articles. Just as we needed an "a" before "protozoan parasite," we need an "a" before "single cell."
So, then you would have:
A protozoan parasite consists of
a single cell and its tiny usually cannot see it without using a microscope.
It's still not correct! Now we have to turn to punctuation. You have written "its" when you mean "it is." It's fine to use the contraction, but you must remember the apostrophe or the word has a different meaning. Also, you have combined two sentences into one, leaving out the subject of the second sentence.
Fixing all of those things, you would have
A protozoan parasite consists of a single cell
, and it
' s tiny
; you usually cannot see it without using a microscope.
As you can see, that took a lot of time. This is why I would like to see you take a lot of time going over your sentences carefully, looking first at noun and their articles, then at verbs, and finally at punctuation, before posting the essay as revised.
