假设条件句

一般说来，假设条件句的谓语动词时态是后移的：过去时形式用来指现在时间，过去完成体形式用来指过去时间。

More generally , the verbs in the hypothetical conditional clauses are backshifted , the past tense form being used for present and future time reference and the past perfective form for past time reference .

在假设条件句的两个分句中，动词的一般规则是：1.若与现在或未来事实相反的假设，条件分句中用的是动词的过去时，母句中则是情态动词的过去时；

The general rule for verbs in both clauses of hypothetical conditions may be expressed thus : for the hypothesis which is contrary to the present and future facts & verb used in conditional clause would be the past tense , and past modal would be used in matrix clause ;

如果我们的论述中有如果，我们在主张先行词，假设条件句或者结果，然后从句，或者我们说如果P那么。

If we got an if then statement are we asserting an antecedent , an if clause or the consequent , Q the then clause , or are we saying if P then Q.

依据假设连词引导这两类假设复句的能力，又将假设连词分为专表可能性假设连词、兼表可能性假设连词和专表反事实假设连词三类。英汉假设条件句比较
