It’s vs. its vs. its’

This is a rule that’s pretty much guaranteed to show up on every ACT and SAT, and knowing it can get you an easy couple of points.

 

It’s = It is

Correct: It’s very rainy outside today, but it might be sunnier tomorrow.

Incorrect: Its very rainy outside today, but it might be sunnier tomorrow.

 

Its = Possessive form of “It”

Correct: The book has lost its cover.

Incorrect: The book has lost it’s cover.

 

Its’ = does not exist

 

It’s vs. its can be tricky because nouns with apostrophes are possessive (e.g., the boy’s hat = the hat that belongs to the boy). As a result, many people very logically mistake it’s ( a pronoun) for the possessive form. Note that on the ACT, its is almost always the correct answer for precisely this reason.

There is, however, a simple trick.

If you see both it’s and its show up as answer choices and aren’t sure which one to choose, plug in it is. If the sentence makes sense, you need the apostrophe; if it doesn’t (much more likely), you don’t need the apostrophe.

 

Incorrect: Florida, the site of some of the first European settlements in North America, increased it’s population very slowly after being established as a state.

Plug in: Florida, the site of some of the first European settlements in North America, increased it is population very slowly after being established as a state.

Correct: Florida, the site of some of the first European settlements in North America, increased its population very slowly after being established as a state.

 

Finally, remember that its’ does not exist. (Nor, for that matter, does its’s, which has been known to appear on occasion.) The plural of its is their. Any answer that contains its’ can be automatically eliminated—no exceptions. 

No comma between compound items (subjects, objects, verbs)

This is one of the most common errors involving commas on the ACT, and it’s one that’s very easy to identify and fix.

A compound item is simply two nouns or verbs joined by the word “and.” The rule is that you never need a comma before the “and.”

If the grammatical terminology makes you too nervous, there’s also a great shortcut: comma + and = period, and if you plug in a period, you won’t have two full sentences. Since the period isn’t correct, “comma + and” isn’t correct either.


Compound Subject Errors

Incorrect: The cover, and the binding of the old book are beginning to disintegrate.

Period replaces “comma + and:” The cover. The binding of the old book are beginning to disintegrate.

Correct: The cover and the binding of the old book are beginning to disintegrate.


Compound Object Errors

Incorrect: The book has many pages, and illustrations.

Period replaces “comma + and:” The book has many pages. Illustrations.

Correct: The book has many pages and illustrations.


Compound Verb 

Incorrect: The cover of the old book is beginning to fade, and disintegrate.

Period replaces “comma + and:” The cover of the old book is beginning to fade. Disintegrate.

Correct: The cover of the old book is beginning to fade and disintegrate.

How to use a colon

For some reason, colons have a tendency to make people nervous. There’s really no reason for concern, though, because there are only three things you need know in order to use them flawlessly.


Colons can be used in two situations:


1) Before a list

New England consists of six states: Maine, Vermont, New Hampshire, Massachusetts, Rhode Island, and Connecticut.


2) Before an explanation

Correct: I spoke to my supervisor, and this is what she said: I should come in early tomorrow morning in order to make up for the shift that I missed last night. 

The first half of the sentence sets up the information after the colon, which explains what the supervisor said. 

 

Let’s look at a slightly more challenging example.

Correct: The Greek goddess Athena was a complex figure: she was a patron of the arts and music, but she also was a warrior who was typically depicted as wearing armor and carrying a shield.

Again, the second half of the sentence expands on the first — it explains why Athena was a complex figure. 

 

Now, there is an additional requirement:

The sentence before a colon must be able to stand on its own as a complete thought. 

For instance, in the second example above, the statement The Greek goddess Athena was a complex figure is both a grammatically complete sentence and a statement that makes sense on its own. 

 

In contrast, we cannot say this: 

Incorrect: The Greek goddess Athena was: a complex figure. 

Even though The Greek goddess Athena was is technically a complete sentence because it contains a subject (The Greek goddess Athena) and a verb (was), it does not make sense as an independent thought. 

 

One more example. 

Incorrect: In recent years, forest fires have become: an increasing threat in the United States and abroad.

Because In recent years, forest fires have become does not make sense as an independent statement, it should not come before a colon.

Correct: In recent years, forest fires have become an increasing threat: they burn earlier and later in the year, both in the United States and abroad. 

Because In recent years, forest fires have become an increasing threat does make sense on its own, it can come before a colon.

 

No That = No Comma

Questions that look like the following appear on the English portion of virtually every ACT:

What do you get when you cross a chicken with an apple? A daffodil with rice? A flounder with a tomato? These aren’t jokes, waiting for a punch line.

A. NO CHANGE
B. jokes waiting
C. jokes, waiting
D. jokes, waiting,

Although this appears to be a question about commas, it’s actually about something else entirely: relative clauses. Now, the term “relative clause” is one that I avoid whenever possible; it tends to make people a little bit nervous. It also sounds kind of icky and grammatical, the sort of thing that’s so absurdly complicated that it makes you want to throw up your hands in utter defeat before you’ve even started to try to understand what it is.

Here’s the thing, though: relative clauses aren’t actually that hard. And in order to be certain about these questions — which can be among the trickiest English questions on the ACT — it really helps to understand the basic grammar behind them.

Relative pronouns are words like which, who(se), and that. They are frequently used to connect two sentences that would sound stiff and unnecessarily repetitive when written separately.

Who

Without relative pronoun: I saw a man. The man was eating a hamburger.

With relative pronoun: I saw a man who was eating a hamburger.

That

Without relative pronoun: This is the book. I read the book yesterday.

With relative pronoun: This is the book that I read yesterday.

It is also possible to join the sentences and create a relative clause without using a relative pronoun. For example:

Correct: I saw a man who was eating a hamburger.

OR

Correct: This is the book that I read yesterday.

When you get rid of the relative pronoun, however, you do not ever need to replace it with a comma — but this is exactly what the ACT does. And in the vast majority of instances, the pronoun in question will be that:

Correct: This is the book that I read yesterday

Correct: This is the book I read yesterday

Incorrect: This is the book, I read yesterday.

Which brings us back to the original question. The underlined portion of the sentence is in fact a relative clause. It could have also been written this way:

These aren’t jokes that are waiting for a punch line.

But since the relative pronoun that doesn’t appear in the sentence, no comma is necessary. The answer is therefore B (“These aren’t jokes waiting for a punchline.”)

Recognizing these questions can take a little bit of thought — they’re easy to overlook if you’re not expecting them to be there. But since there’s at least one on pretty much every single test, learning to recognize them can get you a guaranteed point or two.

Don’t just read the lines you’re given

SAT and ACT Reading Tip: Whenever a question gives you a set of line numbers to refer to, always start a few lines above and read to a few lines below to establish context.

One of the most common errors that test-takers make on both the SAT and ACT Reading is to read only the lines referred to in the questions. After all, if the question refers you to line 15, then shouldn’t the answer be in line 15?

Here’s the problem, though: it might not be.

A line reference only tells you that a particular word or phrase appears in a given place. It does not indicate that the answer is necessarily in that place.

Remember: a lot of the time you’re being asked to identify the role a particular set of lines plays within a larger argument, and frequently that role isn’t apparent from reading the lines themselves. It’s apparent from what comes before…occasionally after.

In general, if the lines in question are relatively close to the beginning of a paragraph, you want to start from the beginning of paragraph. Think of it this way: the role of most information in a paragraph is to support the point made in the topic sentence, so if you go straight to the topic sentence, you’ll automatically get the point of the rest of the information. And chances are you’ll save a whole lot of time.
