3、祈使句。 No smoking! 禁止吸烟 !No fishing! 禁止钓鱼 ! 3. 祈使句的回答 祈使句的动作通常是表示将来发生的动作,所以回答祈使句时,一般用 will 或 wont。 在回答具有否定意义的祈使句时,要注意两点: 1) 形式一致 (即 Yes 与 will 保持一致; No 与 wont 保持一致 ) 2) 意思相反 (即 Yes 是 “不”的意思; No 是 “是”的意思 )。 在回答时,要注意分析上下文语境中所提供的条件。 如: - Dont go out, please. Its raining heavily outside. 请不要出去。外面雨下得很大。 -

(2) 否定祈使句的反意疑问句反问部分只用 will you。 Dont be late again, will you? 别再迟到了,行不行? (3) 以 lets 开头的祈使句反意疑问句反问部分用 shall we。 Lets turn on the
5、 TV, shall we? 我们把电视打开,好吗? 只有以 lets 开头的祈使句的反意疑问句的反问部分才用 shall we,而 let us 开头的祈使句的反意疑问句的反问部分应为 will you 或 wont you.如: Let us stay here, will/ wont you? 请(你)让我们留在这好吗? 练习题 一 . 用括号内所给动词的适当形式填空。 1.

10、首,其它部分用陈述句语序。 一、 由 “what“引导的感叹句: “what“意为 “多么 “用作定语,修饰名词(被强调部分),单数可数名词前要加不定冠词 a/an,复数可数名词或不可数名词前不用冠词。这类句子的结构形式是: what+(a/an)+adj.+n.+主语 +谓语 . 如: What a clever girl she is! 多么聪明的姑娘呀!

How nice the pictures are! 多么漂亮的图画呀! How happy they lo
12、ok! 他们显得多么高兴呀! How well she sings! 她唱得多好呀! How hard they are working now! 他们干得多么起劲呀! 三、在表示同一意义时,英语感叹既可用 “what“引导,也可用 “how“引导。如: Wha t a hot day it is! = How hot the day is ! 多么热的天气呀! What tall buildings they are! = How tall the buildings are! 多么高的楼房呀! What bad weather it is! = How bad the weather is
13、! 多么糟糕的天气呀! What bright sunshine it is! = How bright the sunshine is! 多么明亮的阳光呀! 4 四、感叹句在表示激动强烈的感情时,口语中常常采用省略句,其后面的主语和谓语往往略去不讲。 如: What a fine day! 多么晴朗的天呀! What an honest boy! 多么诚实的孩子呀! What red apples! 多么红的苹果呀! How cool! 好凉快呀! How wonderful! 精彩极了! 练习题 一、填入适当的词完成下列感叹句。 1)._ difficult homework we had

19、分倒装 。 在倒装语序中若整个谓语都在主语之前称为全部倒装;若谓语的一部分(情态动词或助动词)位于主语之前称之为部分倒装。 一、 全部倒装 1、 以介词开头的地点状语位于句首。 例: In front of the house stand a lot of trees. 注:谓语动词要与其后的主语保持时态和数的一致。 2、表示时间和方位的副词 there, here, out, off, now, up, down 等 ,位于句首。 例: Here came a bus. 注:若主语是人称代词时则用正常语序。如: Here you are. 3、 such 位于句首。 例: Such was
20、Doctor Li. 4、表语 位 于句首。 例: Gone are the days when we lived in that city. 5、直接引语的一部分或全部位于句首。 例: “Dont do it again!” said the mother to her son. 注:如果主语是代词时则 不 倒装。如: “What are you doing?” he asked. 6 6、为了使全句平衡,而将较长的主语放在句末。 例: Among these men was a man called Tom. 二、 部分倒装 1、否定词或否定短语位于句首时 ,常见的否定词或否定短语有: n
21、o, not, never, hardly, scarcely, little, seldom, not until, no sooner than , hardly when , not only but also , in no time, in no way, by no means 等 . 例: Never did I saw it. Not until she went home did I leave.(主句倒装,从句不倒装。) 注:上述句子中的否定词或短语不位于句首时,句子结构不倒装。 2、 so/such + adj/adv + that 句型位于句首,表程度。 例: So d
22、irty is the cloth that we cant use it. 3、表示程度、方式、时间频率的状语位于句首且表强调时 ,常用的状语有 : always, often, once, every day, usually, many a time, now and then 等。 例: Often did I tell you not to do it. 注:若不表强调时,也可用 Often I told you not to do it. 4、在虚拟语气中,当连词 if 省略时,助动词移到句首。 were had 主 should 例: Were I in your place,
23、I wouldnt agree with her. 5、 as 或 though 引导的让步状语从句(只需将表语、状语或动词原形提到 as 或 though 之前)。 例: Hard as he studied, he failed. Try as they might, they couldnt do it better. Child as he is, he is brave. 注 : 作表语的单数可数名词放在句首时,冠词要省略。如例 。 6、 Only+状语位于句首。 例: Only in this way can we do it better. 注: only 位于句首修饰 主 语时
24、,则无需倒装。如 Only I can do it. 7、 neither nor 连接两个句子时,两个句子都要倒装。 例: Neither will they study nor will they play. 8、 no sooner than ; hardly scarcely when 表示 “一 就 ”时,从句用过去完成时(倒装)主句用过去时。 例: No sooner had I got home than it began to rain. 9、代词 so, nor, neither 位于句首,表示谓语所述情况与上句的 “也一样 ”或 “也不一样 ”(主语不同)时。 例: I s
25、aw the movie, so did he. I dont smoke, nor do you. 注: 前面所说的内容既有肯 定又有否定或前后的谓语动词形式不一致时,用 “It is the same with +主语 ”结构或 “So it is with+主语 ”结构。 如: She is a teacher and she enjoys music, so it is with me. so+主语动词( be 动词助动词情态动词)则表示对前句内容的肯定和附和,译成 “确实,就是 ”。 如 : John studies hard, so he does. 7 10、强调宾语,表语、状语
26、时,将其位于句首。 例: Very strange it looks.(强调表语 ) Very good holiday we had last year.(强调宾语 ) 11、在一些 “祝愿句 ”中。例: May you succeed! 练习题 1. -“ Look ! Here _.” -“Oh, thank God .
