If you begin to understand what you are without trying to change it, then what you are undergoes a transformation." j.krishnamurti.

Explanation:

 So, I am going to explain all kind of verb forms like present and past and how can you use them in a sentence.

  A) SIMPLE PAST

We use the SIMPLE PAST for something that we start on the past and just finished. We didn't continue this on the present, nor on the future. Examples:

I visited my mother last year (I did it and finished)

I traveled to NY last month and it was great (I did it and finished)

However, we have two kind of verbs that I need to explain here: regular verbs and irregular verbs.

When we talk about regular verbs, whether you want to write a sentence on the past, you must to add on the final of the verb "ED" or "IED". But, how can you know if the verb is regular? Just practice and try to fix it, to fathom all the contents you are able to fix. Here are some example:

He worked so hard today. The verb "to work" is regular and for this reason you have to add "ED".

 However, when the verb ends in "y" it loses the letter "y" and gains "ied" and the following example: I studied english all night long. The verb "to play" has "y" on the final, so you have to take it and add "ied".

I carried all my luggages. The verb is "to carry".

However, when "y" is preceded by a vowel, we just add "ed".

To play. I played soccer last night

When the consonant is at the end of the tonic, we do not double the consonant, just add "ed".

Examples:

Listen - Listened

Open - Opened

The irregular verbs have different flexions in simple past, and do not follow any rules. See some examples:

Eat - Ate

Make - Made

Cut -cut

Drive - Drove

Do- did

keep- kept

How can you know if the verb is regular or irregular? You must to decorate it, to practice, to study and then try to fix it in your mind.

The general formula to make senteces on the simple past is the following:

SUBJECT + VERB(SIMPLE PAST) + COMPLEMENT

Whether you want to make sentences into negative or interrogative form, you have to use the auxiliary verb "DID". For instance:

Did you travel to USA last month? Look that the "verb" is on the infinitive and not on the past. The reason is that we already have the auxiliary verb on the past "DID".

 Negative form is the same way.

I did not study english/ I didn't study english

B) PRESENT PERFECT.

We use "PRESENT PERFECT" to talk for something that started on the past and is still happening on the presente and maybe is going to continue on the future. Examples: I have started my english studies when I was about 7 years old (It means I am studying now, I started and I continue studying english).

 However, when you want to use the PRESENT PERFECT. it's such a different about the verbs you are going to use.  The kind of verbs you have to use is "PARTICIPLE" and not like the simple past. For example:

The verb "to get" is irregular. If you want to make phrases on the simple past, you have to use "got". But, if you want to makie phrases using Present Perfect, you have to use "gotten".

I got sick yesterday- SIMPLE PAST

I have gotten sick every day- PRESENT PERFECT

As you can see, you have to fix all the verbs regular and irregular and if the verb is PARTICIPLE OR ONLY SIMPLE PAST.

  However, when we talk about PRESENT PERFECT, we have to think about the verb "HAVE". The general formula is:

SUBJETC + HAVE/HAS + VERB(PARTICIPLE) + COMPLEMEN

I HAVE WORKED IN THIS COMPANY FOR TWO YEARS (I'M STILL WORKING IN THIS COMPANY IN THUS CURRENT DAY).

Now let's talk about PRESENT. I'm going to explain here one kind of PRESENT we can make: SIMPLE PRESENT

A) SIMPLE PRESENT. You use it for something on the present, can be a routine, your day by day, something that you always do, etc. Here are some examples: I wake up every day at about six o'clock

I love to eat apple, orange and grapes.

But, if the subject is "singular third person" like (he, she, it), you have to add "es", "ies" or "s" on the final of the verbs. Examples:

She studies english so hard. The verb is "to study". This verb end with "y" and before it you have a consoant, so you have to take "y" and add "ies".

I plays soccer every week

She goes to the supermarket every morning.

If you want to make phrases into negative or interrogative form, you have to  use the auxiliaries following auxiliaries verbs: DO and DOES.

You use DO with the following subjects (I, we, you, they) and you use DOES with (he, she, it).

Example:

Do you speak english?

I do not speak english

Does she speak english

She does not speak english

The general formulas about simple present are:

A) AFFIRMATIVE

SUBJECT + VERB + COMPLEMENT

B) NEGATIVE

SUBJECT + DO/DOES + NOT + COMPLEMENT

C) INTERROGATIVE

DO/DOES + SUBJECT + VERB + COMPLEMEN?

DON'T FORGET TO ADD "S" "ES" OR "IES" ON THE FINAL OF THE VERBS, WHEN YOU MAKE PHRASES USING SIMPLE PAST ON AFFIRMATIVE FORM. DO NOT USE THIS RULE WHEN THE SENTENCE IS ON INTERROGATIVE OR NEGATIVE FORM.

Answer:

c. a potential decrease in the species of fish

Explanation:

Dams block the migration of fish, deplete oxygen from rivers, and interfere with the biological triggers that guide fish. They also reduce self-cleaning ability of rivers. Due to the construction of dams and other factors, the population of freshwater fish species declined 37% between 1970-2008 - more than the populations of all other ecosystems. Populations of tropical freshwater fish species declined by as much as 70%.
