SUBJECT/VERB AGREEMENT

The subject of a verb affects the verb.
A verb in present tense form changes depending on the subject.

I walk we walk
you walk you walk
he/she/it walks they walk

Notice that when the subject is he, she or it, you need to add an “s” to the end of the verb. The same is true when the subject is a noun such as Cathy, a pen, or Vancouver. If you replace these nouns with a pronoun, they are replaced with he, she or it.

He washes the dishes every day. John is usually late.
They wash the dishes every day. John and Susan are usually late.

Exercise 1: Choosing singular or plural verb forms.

Circle the subject in each of the following sentences. Then underline the correct verb form and cross out the incorrect verb form.

Example:

Every morning Peter (walk/walks) to the park.
Here you would underline walks, and cross out walk.

1. He always (take/takes) his dog.
2. The dog (is/are) called Bear.
3. Bear and Peter especially (like/likes) walking through the woods.
4. After their walk, they often (go/goes) to the coffee shop.
5. Bear sit/sits outside and wait/waits while Peter get/gets a coffee.
6. Then they sit/sits outside and watch/watches the people go by.
7. When Peter finish/finishes his coffee, Bear and Peter go/goes home.
8. At home, Bear lie/lies down have/has a nap, and Peter leave/leaves for work.

Complications with Subject/Verb Agreement:

Exercise 1 is not difficult, but subject/verb agreement isn’t always so easy. Things that confuse writers about subject/verb agreement include:

♦ The subject doesn’t look plural, but it is.

♦ The subject is a noun we don’t count.

♦ Words come between the subject and the verb.

♦ The subject is a word like who, which, or that.

♦ The verb comes before the subject.

♦ The subject is an indefinite pronoun like each, anybody or both.
Each of these is explained here.

♦ The subject doesn’t look plural, but it is.
Usually plural nouns in English have an “s” or “es” on the end. However, some plural words do not end in “s”. For example, people, children, sheep and mice can all be plural words. So, the subject is treated like they when you use these words. The question to ask yourself is, “Am I talking about one or more than one?” In this example, Most children love chocolate., you are writing about more than one child. Most children can be replaced by they. Therefore, the verb does not get an “s”.

♦ The subject is a noun we don’t count
In English, some nouns are not counted. For example, we don’t count water, happiness or gold. We might count glasses of water or liters of water, but we don’t count the water itself. We cannot say one water or two waters. When we use non-count nouns like these, we treat the subject as singular. For example, we might say, Water is a precious natural resource. Water in this sentence can be replaced by it, so we treat water as a singular subject.

• Words come between the subject and the verb:

Sometimes people get confused about the subject of a verb. This often happens when other words come between the subject and the verb. Look at these examples. Which one is correct?

a) The potatoes in the fridge are left over from last night.
b) The potatoes in the fridge is left over from last night.

To decide on the correct verb form, you need to decide which noun is the subject. What is left over, the potatoes or the fridge? Clearly, it is the potatoes. Therefore, the verb is controlled by the potatoes. The correct answer is a). The words in the fridge are between the subject and the verb.

When you decide on subject/verb agreement, you need to ask yourself, “What is the real subject of this verb?” It is a mistake to only look at the noun that comes before the verb.

Exercise 2: Choosing the correct verb form: complications 1, 2 and 3:

Circle the subject in each of the following sentences. Then underline the correct verb form and cross out the incorrect verb form.

1. The cost of mattresses has/have gone up lately.
2. People often forget/forgets the importance of free time.
3. Brown rice is/are nutritious.
4. The homework for those classes is/are very time-consuming.
5. The equipment in those storage rooms is/are used by gym classes.
6. Unfortunately, many children in Mexico City lives/live on the streets.
7. My notes from that class isn’t/aren’t very hard to read.
8. Iron rusts/rust easily in wet weather.
9. The buildings under the bridge seems/seem empty.
10. The students in her class doesn’t/don’t like her exams.

• The subject is a word like who, which or that.
Look at the following example.
This course is not for people who hate writing.
This sentence has two verbs. Can you find them? The first verb is is. The subject of is is this course. The second verb is hate. The subject of hate is who. Now look at the next example.

"She met a man who works for the phone company".

In this sentence, there is also a who subject. Who is the subject of the verb works. So, in the first sentence the subject who takes a verb without an “s”, but in the second sentence, the subject who takes a verb with an “s”. Can you explain why both are correct?
The reason both who hate and who works are correct is that the verbs are controlled by the noun who refers to. The who in who hate refers to people, a plural noun. The who in who works refers to a man.

When we use who, that or which, we have to look at what noun those words are referring to. Then we can decide on the subject/verb agreement.

Exercise 3: Choosing the correct verb form – complication 4 :

Circle the subjects in each of the following sentences. Then underline the correct verb form and cross out the incorrect verb form.

1. They lives/live in a city which has/have a high crime rate.
2. She goes/go to Douglas College which has/have three campuses.
3. John and his friend Lisa eats/eat at a restaurant which is/are near the skytrain station.
4. The man that was/were in the front row is my father.
5. That movie isn’t/aren’t for people who scares/scare easily.
6. Claire and Amanda shares/share an apartment which has/have two bedrooms.

• The verb comes before the subject

When the verb comes before the subject, some people get confused about subject/verb agreement. Look at the following sentences.

- In the corner of the living room are two china dogs.
- There is a stain on the carpet.
- Why are Paul and Simon so tired?

In each of these sentences, the verb comes before the subject.
The first step in deciding on the agreement is to find the verb in each sentence.
To find the subject, ask yourself a who or what question about the sentence. For example, you might ask, “Who or what are in the corner of the living room?” The answer is two china dogs.
Therefore, two china dogs is the subject of the verb. If there was only one china dog, look what would happen to the sentence.

"In the corner of the living room is one china dog".


Exercise 4: Choosing the correct verb form – complication 5:

Circle the subjects in each of the following sentences. Then underline the correct verb form and cross out the incorrect verb form.

1. There is/are ants on the windowsill.
2. When is/are the movies starting?
3. Under the pillow is/are a quarter.
4. In the sky is/are millions of stars.
5. There is/are 25 students in that class.
6. Why does/do the student always come late?

♦ The subject is an indefinite pronoun like each, anybody or both
Most indefinite pronouns are treated as singular nouns. They include:
one, anyone, everyone, someone, nobody, anybody, everybody, somebody, nothing, anything, everything, something, each, either and neither.

For example, we say:

Everybody is coming at 6:00.
The only indefinite pronoun that we treat as plural is both.

For example, we say:
Both are late for class.

Exercise 5: Choosing the correct verb form – complication 6:

Circle the subjects in each of the following sentences. Then underline the correct verb form and cross out the incorrect verb form.

1. One of my friends is/are from France.

4. Each of the girls is/are wearing her best dress.
5. Nobody likes/like that restaurant.

THE COLUMBIA ICEFIELD

The Rocky Mountains, on the border of the provinces of Alberta and British Columbia, has many attractions for tourists. One attraction is the Columbia Icefield. This huge field of ancient ice cover 125 square kilometers. The Athabasca, Stutfield and Dome glaciers make up the icefield. As the ice melts, the water flow into four major river systems. These systems is the Columbia, Fraser, Mackenzie and Saskatchewan. The meltwater flows down these rivers into three different oceans, the Pacific, Arctic and Atlantic. This high point in a continent’s water system is called a “hydrological apex”, and the Columbia Icefield is one of only two such apexes in the world. Tourists visit the icefield from April to October each year. Walking tours and snowcoach tours is available. Many people go to the icefield because it is the biggest area of ice and snow in North America south of the Arctic Circle.

THE BEAVER

The beaver, Canada’s national animal, have some unusual characteristics. One unusual fact about beavers is their large size. The beaver is the largest rodent in North America, weighing from 13 to 35 kg. It spend a lot of time in the water, so its feet is large and webbed for swimming. The beaver’s tail which is wide and flat like a paddle also helps it to swim. Thick underfur keep the beaver warm and dry, even in very cold water. In fact, beavers have been known to stay under water in icy ponds for as long as fifteen minutes. Beavers also has long teeth which grows all their lives. They use these powerful teeth to cut down trees which they use for food and and shelter. Another unusual fact about the beaver is that it is one of the few animals that change its own environment. Beavers create ponds by building dams with roots, sticks, mud and stones. Each family of beavers build a lodge, or nest, in a riverbank or in the middle of a pond. They build an underwater entrance to the lodge. Having the entrance underwater protects them from their enemies. Beavers is also very social animals. They not only communicate with each other by making sounds with their mouths but also by slapping their big flat tails on the water. The beaver’s social life is complex and focus around the female. These very special animals are found in every province in Canada.
