imperfect tense造句

• Instead of considering the imperfect tense as a specific tense , consider it as a time reference
  我们最好不要将未完成式视为一具体时式，而是视之为一参考性质的时间座标。
• So , if the main verb is in the present tense , the imperfect tense will be translated as a present
  （拉丁文）主要子句的动词为现在式，则（拉丁文）附属子句的未完成式动词要译成英文的现在式。
