Conditionals can be a confusing aspect of the English language to grasp for both ESL and native speaking students. However, like many other aspects of second language acquisition, the concept can be considerably more difficult for ESL students.
Different languages approach conditionals in different manners, so ESL lessons that address conditionals will be interpreted differently by students depending on their native language. The following sections cover the concept of conditionals and suggest teaching strategies that could be implemented for your students.
Conditionals are sentence structures that explain a particular situation or circumstance and its consequences. If this happens, then that happens. Conditionals are commonly referred to as "if sentence structures" because they often contain the word "if."
There are four main conditionals that are commonly used in the English language: first conditional, second conditional, third conditional and zero conditional.
The first conditional deals with issues that have a real possibility of occurring. This conditional typically deals with future, real world events that are pondered on a daily basis. When people make plans and suggest back up plans, they are utilizing the first conditional.
The first conditional uses the if/then structure and the words will, shall, can or may to convey the future action being considered. The following sentences are examples of the first conditional:
The second conditional is a bit more tricky. In some ways it is similar to the first conditional. It utilizes the same if/then structure, but instead of using the words will, shall, can, or may, the second conditional uses would, could, or might. The most significant difference between the second conditional and the first conditional, however, is that the second conditional deals with events that are not real possibilities. In many cases, the events could happen; they are not physical impossibilities. However, they are not tangible events that are certain to impact daily life.
In many respects, the second conditional is what English speakers use when they are dreaming about something or fantasizing about a particular scenario. See the following sentences for examples of the second conditional:
While the first two conditionals talk about possible future events, the third conditional deals with the past. Specifically, the third conditional talks about events in the past and ponders the effects of those events not happening.
Because we can't go back in time, the third conditional deals with events that have no possibility of happening. The third conditional uses the words would have to convey these impossible events. The following are examples:
The zero conditional deals with issues that are always true. They can often be thought of as stating a scientific fact. The following are examples:
When teaching conditionals for ESL students, it is most useful to construct your lessons so they follow a logical progression through the four conditionals.
This process is useful for all student populations, but particularly for ESL students who may require additional time and practice to fully grasp some of the more obtuse concepts. Be as flexible as possible with your schedule, and move on when the students are ready.
