Hello, fellas. How’s life today? On this occasion we will learn several forms of conditional sentences. According to Betty Schrampfer Azar, a conditional sentence usually comprises of an adverb clause of condition or if-clause, which contains a condition, and a result clause, which shows a result. Besides, an adverb clause can be introduced by whether or not, even if, in case, in the event that, unless and only if.

Conditional sentences can also be formed by using as if, as though and like. The use of as if or as though usually carries the same meaning as an untrue conditional sentence.
1) She kept playing as if she were a child.
Fact: She is not a child.
2) He explained the lesson to his classmates as though he had learned all the materials.
Fact: He did not learn all the materials.
In conditional sentences, like precedes a clause. However, it is not generally considered appropriate in formal English and more common in informal English.
It looks like it is going to be sunny.
