We spend a good deal of our lives comparing and contrasting things Whenever we want to explain

something, for example, we often use comparison (showing how two or more things are

similar) We might say, for example, that mint chocolate chip ice cream tastes just like a York

Peppermint Pattie; or that the new manager looks just like Clint Eastwood When we want to show how things

are different or not alike, we contrast them We might say that York Peppermint Patties are mintier than any mint

chocolate chip ice cream; or that the new manager may look like Eastwood, but he doesn’t have Eastwood’s dimple

Similarities and Differences:

C o n t r a s t Wo r k

When writers compare and contrast, they provide a way

of classifying or judging the items they are discussing

They show how two (or more) things are similar or

dif-ferent when placed side by side Consider, for example,

the following paragraph Read it carefully, and then

answer the questions that follow

Planting a garden is a lot like having a family Both

require a great deal of work, especially as they grow

and as the seasons change As summer days

lengthen, your plants become dependent on you for

sustenance, much like your children depend on you

for food and drink Like a thirsty child asking for a

drink of water, your plants do the same Their bent,

wilted “body” language, translated, issues a demand

much the way your child requests milk or juice

When their collective thirsts are quenched, you see

the way they both thrive in your care The fussy

child becomes satisfied, and the plant reaches toward

the sun in a showy display You might also find that

you have to clean the space around your plants much

like you would pick up toys and clothes that have

been thrown helter-skelter in your toddler’s room

Similarly, plants shed spent petals, roses need to be

pruned, and weeds need to be pulled To keep

chil-dren healthy, parents protect their chilchil-dren against

disease with medicine, and gardeners do the same

with insect repellent To nourish them, parents give

children vitamins, and gardeners use fertilizer, as

both promote healthy growth As children grow and

become adults, they need less and less care However,

here’s where the similarity ends While plants die and

become dormant during winter, children still

main-tain a vital role in the family unit

Finding the Facts

1 What two things are being compared and

contrasted here?

2 In what ways are these two things similar?

(There are four similarities; list them here.)

a.

b.

c.

d.

3 In what ways are these two things different?

(There is one aspect that is different; write it here.)

Answers

1 The two things being compared and contrasted are

a parent and a gardener

2 Gardeners are like parents in that: a) plants are

dependent on gardeners as children are on parents; b) plants require care from gardeners as children

do from their parents; c) gardeners tidy up after their plants, as parents do after children; and d) gardeners protect their plants, as parents protect their children

3 Gardeners are unlike parents in that their

respon-sibility for their plants ends when the plant dies or goes into winter dormancy

Finding the Main Idea

Now that you’ve answered those questions, consider

one more Read the previous passage again, and then

answer this question:

4 What is the main idea of this passage?

Did you notice that the opening sentence, “Planting

a garden is a lot like having a family,” is the topic

sen-tence that expresses the main idea of this paragraph?

The paragraph does mention a difference between these

two roles, but notice that the topic sentence does not

claim that gardeners and parents are exactly alike.

Instead, it asserts that they are “a lot” alike

Transitional Devices

As you read the paragraph about gardeners and parents,

did you notice the transitional words and phrases that

show you when the writer is comparing (showing

sim-ilarity) and when the writer is contrasting (showing

dif-ference)? Here’s the passage once more As you read it

this time, underline the transitional words and phrases

you find

Planting a garden is a lot like having a family Both

require a great deal of work, especially as they grow and

as the seasons change As summer days lengthen, your

plants become dependent on you for sustenance,

much like your children depend on you for food and

drink Like a thirsty child asking for a drink of water,

your plants do the same Their bent, wilted “body”

language, translated, issues a demand much the way your child requests milk or juice When their collective thirsts are quenched, you see the way they both thrive

in your care The fussy child becomes satisfied, and the plant reaches toward the sun in a showy display You might also find that you have to clean the space around your plants much like you would pick up toys and clothes that have been thrown helter-skelter in your toddler’s room Similarly, plants shed spent petals, roses need to be pruned, and weeds need to be pulled

To keep children healthy, parents protect their children against disease with medicine, and gardeners do the same with insect repellent To nourish them, parents give children vitamins, and gardeners use fertilizer, as both promote healthy growth As children grow and become adults, they need less and less care However, here’s where the similarity ends While plants die and become dormant during winter, children still maintain

a vital role in the family unit

There are several transitional words and phrases writers use to show comparison and contrast In this paragraph, you should have underlined the following

words: much like, in the same way, similarly, and however.

These words and phrases show similarity:

These words and phrases show difference: but

on the other hand however

conversely

yet

on the contrary nevertheless

similarly likewise like just as

in the same way

in a like manner and

also

Now look more closely at the sample paragraph to

examine its structure Exactly how is this paragraph

organized?

First, you’ve noticed that the paragraph begins

with a topic sentence that makes the initial comparison:

“Gardeners are like parents.” Then, the paragraph

iden-tifies four ways in which gardeners are like parents:

1 Plants become dependent upon gardeners as

children do on parents

2 Plants require care from their gardeners as

chil-dren do from parents

3 Gardeners clean up after their plants as parents

do after children

4 Gardeners protect plants from “dangers” as

par-ents protect children

Finally, after pointing out these similarities, the

paragraph concludes by pointing out an important

difference between parents and gardeners:

1 A gardener’s responsibility for his or her plants

ends with time while a parent’s doesn’t

Perhaps you noticed something else in the way

this paragraph is organized Did you notice that every

time the paragraph mentions something about a

par-ent’s role, it also mentions something about a

gar-dener? Each aspect of the gardener’s role is followed by

a comparable aspect of the parent’s role Thus, for

every aspect of “A” (the gardener), the paragraph

pro-vides a comparable aspect of “B” (the parent) to

com-pare or contrast The paragraph is therefore organized

like this: ABABABABAB

On the other hand, some writers prefer to deal first with all aspects of A and then with all aspects of B

This is called the block method of comparison and

con-trast; it goes AAAAABBBBB Here is the same para-graph arranged using the block method:

Planting a garden is a lot like having a family A plant becomes dependent on the gardener and begs for water on a hot summer day Gardeners also have to clean up the space around their plants

as they shed spent petals, as they require pruning, and as they become choked with weeds Garden-ers also provide for the health of their plants through insecticide and fertilizer applications A gardener’s responsibility for his or her plants lessens as they die at the end of the season or they

go into winter dormancy

Like a gardener, a parent finds their children dependent upon them for food and nourishment Like a gardener, a parent is constantly picking up after their children, as toys and clothes are scattered throughout the house Like a gardener, a parent pro-vides for the nourishment and well-being of their children with vitamin supplements, food, and med-icines However, unlike gardeners, parents will find that their responsibility lessens as the child grows, but it does not come to an end

Here, the passage treats each of the things being compared and contrasted separately—first, all aspects

of the gardener, then all aspects of the parent—rather than one aspect of the gardener, one of the parent; another of the gardener, another of the parent So the organization is quite different

But you should notice one thing that is similar in both passages: They compare and contrast aspects of A and B that are comparable or parallel When an aspect of

A is discussed, that same aspect of B (whether similar

Being a parent is a lot like being a gardener Parents

must bathe, clothe, and feed their children Parents

must also create and maintain guidelines for

accept-able behavior for children Also, parents must see to

it that their children get a proper education

Gardeners nurture the plants in their gardens

They pull weeds and prune them to encourage them

to grow They feed them and apply insecticides

They watch them flower and then witness their

demise

You’ll notice that this passage seems to focus on

differences between gardeners and parents rather than

the similarities But is this really a fair contrast? Look at

the aspects of A (the gardener) that are described here

Do they have any relationship to the aspects of B (the

parent) that are described? No And a compare and

con-trast passage can’t be successful unless the aspects of A

and B are discussed comparably These two paragraphs

don’t really seem to have a point—there’s no basis for

comparison between gardeners and parents

Practice

Suppose you were going to write a paragraph that

com-pares and contrasts readers and detectives The

fol-lowing are five aspects of being a reader and five aspects

of being a detective listed Only three items in each list

are comparable Find those three items in each list and

pair them with their matching item Remember, these

items may be either similarities or differences What’s

important is that they are comparable aspects

A reader:

1 Looks for clues to meaning.

2 Has many different types of books to read.

3 Can choose what book to read.

4 Builds vocabulary by reading.

5 Becomes a better reader with each book.

A detective:

1 Has a dangerous job.

2 Gets better at solving crimes with each case.

3 Requires lots of training.

4 Doesn’t get to choose which cases to work on.

5 Looks for clues to solve the crime.

Did you find the aspects that are comparable? Did you match reader 1 with detective 5 (similarity)? Reader 3 with detective 4 (difference)? And reader 5 with detective 2 (similarity)? If so, you did terrific work Here’s how this information might work together

in a paragraph:

In many ways, readers are a lot like detectives Like detectives looking for clues at the scene of the crime, readers look for clues to meaning in the books that they read And, like detectives who get better and better at solving crimes with each case, readers get better and better at understanding what they read with each book Unfortunately for detectives, how-ever, they cannot choose which cases they get to work on, whereas readers have the pleasure of choos-ing which books they’d like to read

 W h y C o m p a r e a n d C o n t r a s t ?

In addition to following the ABABAB or AAABBB structure, compare and contrast passages must, like all other passages, have a point There’s a reason that these two items are being compared and contrasted; there’s something the writer is trying to point out by putting these two things side by side for analysis This reason or point is the main idea, which is often stated in a topic sentence
