Unit 2 Grammar reference and Grammar test
Expressing attitude: Conditional sentences type 3
Conditional tenses are used to speculate about what could happen, what might have happened, and what we wish would happen. In English, most sentences using the conditional contain the word if. Many conditional forms in English are used in sentences that include verbs in one of the past tenses. This usage is referred to as "the unreal past" because we use a past tense but we are not actually referring to something that happened in the past. There are five main ways of constructing conditional sentences in English. In all cases, these sentences are made up of an if clause and a main clause. In many negative conditional sentences, there is an equivalent sentence construction using "unless" instead of "if".
In this article we publish Grammar reference section from Business Result, Unit 2 complimented with a test. The test has two parts: conditional sentences type 3 and conditional sentences mixed type. Below you will find a table with the rule overview.
