Worksheet Overview

QUESTION 1 of 10

A conditional sentence is a sentence in which one thing depends on another.

 

 Result

 Condition

 I will get fit

 if I ride my bike every day.

 

 

The two clauses can be swapped around.

If I ride my bike every day I will get fit.

I will get fit if I ride my bike every day.

 

We sometimes use a comma if the conditional part of the sentence comes first.

If I ride my bike every day, I will get fit.

 

Other conjunctions can be used in conditional sentences as well as 'if'.

Provided it doesn't rain we will go to the beach tomorrow.

There were three different conjunctions used in these sentences. Did you spot them? They were 'if', 'unless' and 'provided'.
  • Question 3

Which word is the conjunction in this sentence?

 

I will help you if you get stuck.

CORRECT ANSWER
if
EDDIE SAYS
The conjunction word was 'if'. It is useful to remember that the conjunction word can join the two parts (clauses) of the sentence together.
  • Question 4

Which word is the conjunction in this sentence?

 

Unless you eat your vegetables you won't get any pudding.

carrot

CORRECT ANSWER
unless
EDDIE SAYS
The conjunction word was 'unless'. In this sentence they have used the conjunction at the start, this is fine, it still makes sense!
  • Question 5

Which word is the conjunction in this sentence?

 

If I lived nearer to school I could get up half an hour later in the mornings.

CORRECT ANSWER
if
EDDIE SAYS
The conjunction word was 'if'. They have used it at the start of the sentence here too. Can you rearrange the sentence so that 'if' is used in the middle? Check that it still makes sense.
  • Question 6

Read this sentence and identify the condition, the conjunction and the result.

 

If I won the lottery I would buy a yacht.

yacht

CORRECT ANSWER

Column A

Column B

condition
I won the lottery
conjunction
if
result
I would buy a yacht
EDDIE SAYS
Wow, a yacht sounds rather fancy, doesn't it? If you won the lottery what would you buy?

Provided you do your homework you can go out to play.

CORRECT ANSWER

Column A

Column B

conjunction
provided

EDDIE SAYS
It may help you to remember that the condition and the result will be the two long parts of the sentence (the clauses) and the conjunction is usually one word that joins these together.
  • Question 8

Read this sentence and identify the condition, the conjunction and the result.

Car

CORRECT ANSWER

Column A

Column B

result
we can't afford to buy a new car
conjunction
unless
condition

EDDIE SAYS
How did you get on? You will notice that the condition and result are closely linked, one can't happen without the other. For example: without Mum's pay rise they can't afford a new car.
  • Question 9

Choose the correct way to complete this sentence.

 

If Manchester United win the Champions League I __________ very happy.

CORRECT ANSWER
will be
EDDIE SAYS
This conditional sentence is talking about something that might happen in the future so the correct answer is 'will be'.
