subjunctive has only the were form Both are remnants of Old English subjunctive mood be subjunctive were subjunctive Happy times always go by quickly and today s story game is coming to an end Today this happy day will remain in our memory forever Part 1 be subjunctive mood The be subjunctive like the imperative is realized by the base form of the verb Whatever the person of the subject the predicator invarably takes the base form Consequently where the clause has a plural subject there is normally no distinction between indicative and subjunctive forms except for the verb be The

the indicative mood or should may infinitive are used instead e g If the news is true everything is possible He hid himself in the bush lest he should be seen Happy times always go by quickly and today s story game is coming to an end Today this happy day will remain in our memory forever In certain formulaic expressions The be subjunctive is also used in some formulaic expressions to express a wish prayer curse The formulaic use of the be subjunctive tends to be formal and old fashioned in style eg God bless you So be it Exercise May our great motherland live long live Happy times always go by quickly and today s story game is coming to an end Today this happy day will remain in our memory forever Part 2 Were subjunctive The were subjunctive has only one form were which applies to

meaning and is used Happy times always go by quickly and today s story game is coming to an end Today this happy day will remain in our memory forever In certain adverbial clauses The were subjunctive is commonly used in adverbial clauses introduced by if if only as if as though though etc to denote an unreal condition or concession eg If I were you I would try my best in the football match If only

well as in non introduced conditional clauses with inverted word order eg Were I to do it I should rely on you He is my best friend my second self as it were Happy times always go by quickly and today s story game is coming to an end Today this happy day will remain in our memory forever Use of past tense forms of verb The past tense forms of verbs are usually used to express hypothesis the following contexts a It is time that It is time that we left home It is high time that you make your decision It is time you went to bed b I would rather that you he Happy times always go by quickly and today s story game is coming to an end Today this happy day will remain in our memory forever I d rather he told me the truth I d rather you had offered me some juice c If only If only I knew her

coming to an end Today this happy day will remain in our memory forever d as if as though He behaves as if he knew him well They are staring at me as if though I was were a stranger He talked as if it

form is not used past tense form Eg The dish tastes as if it is bad It seems as if we will have to stay here for one night e I wish that I wish that I could stay at home I wish I had brought an umbrella with me Happy times always go by quickly and today s story game is coming to an end Today this happy day will remain in our memory forever I wish and I hope both mean 希望 But I hope that doesn t mean assumption so the verb seldom uses past tense form Eg I hope we can go now I hope tomorrow will be a sunny day I hope she will go through it Happy times always go by quickly and today s story game is coming to an end Today this happy day will remain in our memory forever Use of past tense modals The past tense modals are commonly used to express hypothesis in the following contexts Happy
