Unit 4 Learning efficiently Part One: Teaching Design Period 2: A sample lesson plan for Learning about Language (Revise the Subjunctive Mood) Aims To help students revise the Subjunctive Mood To help students discover and learn to use some useful words and expressions To help students discover and learn to use some useful structures Procedures I. Warming up by learning to guessing the meaning of words from context Students should be encouraged to try to guess the meaning of unfamiliar words using clues in the context. These clues may be in the surrounding words. The text may provide a definition that explains the unfamiliar word, or it may give examples to illustrate the unfamiliar word. There may be connecting words used after the familiar word that indicates similarity or contrast. If the student is familiar with the item that is being compared or contrasted this should provide a clue to the unknown word. Another strategy is to break the word down into syllables. Sometimes knowledge of common roots and affixes or similarity to words in the students own language can help them guess the meaning of a particular word. II. Discovering useful words and expressions Turn to page 35 and do the words and expressions exercises 1, 2 and 3. III. Revising the Subjunctive Mood The Subjunctive Mood A verb is in the subjunctive mood when it expresses a condition which is doubtful or not factual. It is most often found in a clause beginning with the word if. It is also found in clauses following a verb that expresses a doubt, a wish, regret, request, demand, or proposal. These are verbs typically followed by clauses that take the subjunctive: ask, demand, determine, insist, move, order, pray, prefer, recommend, regret, request, require, suggest, and wish. In English there is no difference between the subjunctive and normal, or indicative, form of the verb except for the present tense third person singular and for the verb to be. The subjunctive for the present tense third person singular drops the -s or -es so that it looks and sounds like the present tense for everything else. The subjunctive mood of the verb to be is be in the present tense and were in the past tense, regardless of what the subject is. Incorrect: If I was you, I would run. Correct: If I were you, I would run. (The verb follows if and expresses a non-factual condition.) Incorrect: I wish he was able to type faster. Correct: I wish he were able to type faster. (The second verb is in a clause following a verb expressing a wish. It also suggests a non-factual or doubtful condition.) Incorrect: His requirement is that everyone is computer literate. Correct: His requirement is that everyone be computer literate. (Subordinate clause follows main clause with a demand.) Incorrect: He recommended that each driver reports his tips. Correct: He recommended that each driver report his tips. Sometimes we may use the conditional auxiliary verbs of could, should, or would to express the same sense. Subjunctive: I wish he were kinder to me. Conditional: I wish he would be kinder to me. Note: In modern English, the subjunctive is only found in subordinate clauses. Subjunctive form subjunctive present If + s + verb word , s + will + verb word subjunctive past If + s + verb (past tense) , s + would (should, could, might) + verb word subjunctive past perfect If + s + had + p.p , s + would (should, could, might) + had + p.p Meaning subjunctive present real possibility for future subjunctive past not real possibility ; opposite of present fact subjunctive past perfect opposite of past fact IV. Revising useful structures To revise and consolidate your learning of the Subjunctive Mood please go to page 36 and do the three exercises. V. Closing down by reading more about the Subjunctive Mood 1In Conditional Sentences (用于条件句中) 虚拟语气用于非真实条件句时谓语动词的主要形式见下表： 非真实条件句主 句 与现在事 实相反 过去时（ be 用 were） would 动词原 形 与过去事 实相反 过去完成时 would have + 过 去分词 与将来事 实相反或 推测 A. 过去时（ be 用 were） B. were to动 词原形 C. should动词 原形 would动词原 形 以上结构中，主句谓语动词除了用would 外，有时还可用might 或 could，第一人称还 可用 should，但美国英语都用would 。 如果条件句的谓语中含有were, had 或 should 时，有时可省略if 而用把 were, had 或 should 放到主语之前的倒装句。现分别举例如下： 与现在事实相反 If I knew French, I would read the book in the original. If I were (Were I) in your position I would tell her the truth. 与过去事实相反 If you had (Had you) come a few minutes earlier, you would have caught the train. 与将来事实相反或表示推测 If he came tomorrow, I might have time to see him. If it were (Were it) to rain next Sunday, the match would be postponed. If we should (Should we) fail again, we wouldn't lose courage. 2In the That-Clauses ( 用于 that 从句中 ) wish 后的宾语从句 a. 所希望的事与wish 同时发生，从句用过去时，如： I wish you didn't smoke too much. b. 所希望的事在wish 之前发生，从句用过去完成时，如： I wish I had paid more attention to my spelling. c. 所希望的事在wish 之后发生，表示忠告或请求等，从句一般用would动词原形，如： He wishes we would help him in the work. 在表示愿望、请求、建议、打算、命令等意义的词，如suggest, command, demand, decide, propose, order, recommend, request, require, desire, insist, urge 等后的宾语 从句中，以及这些词用于被动语态的主语从句中，都用(should +) 动词原形，如： He suggested that the meeting (should) be held at once. It is desired that Tom (should) get everything ready by ten o'clock. 上述动词转化或派生的名词以及idea, notion, no wonder, a shame, a pity 等后的表语 从句，主语从句或同位语从句中也用(should +)动词原形，如： Our decision is that the school remain closed. It's a pity that he (should) call black white. He made a request that the new electronic instrument (should) be tested at once. 在 It is necessary (important, desirable, essential, amazing, strange, urgent, vital, natural, unusual, possible), etc. 后的主语从句中也用(should +) 动词原形，如： It is necessary that the problem (should) be solved at once. 3In the Clauses and Constructions (用于从句和结构中) as if (though) 引导的从句中（谓语形式和wish 后从句相同），如： He treated me as if (though) I were a child. He acted as if nothing had happened. 在 It's (high/about) time that 后的从句中，从句通常用一般过去时，表示“是.时候了 “，如： It's time you went to bed. 在 would rather/sooner that 的从句中，从句通常用一般过去时，表示“宁愿 “，如： I would rather (sooner) that you started the work at once. 用在含有without, but for, in the absence of等介词或介词短语的句中，表示“要不是 “， 句子谓语形式和wish 后的从句相同，如： Without (But for, In the absence of) the rain, we should have had a pleasant journey.
