初中不定式todo的用法

初中不定式todo的用法

1. 不定式的用法------1.1 不定式作主语 不定式作主语，往往用it作形式主语，真正的主语不定式放至句子的后面。 例如：It's so nice to hear your voice. 听到你的声音真高兴。 It's necessary for you to lock the car when you do not use it. 不用车的时候，锁车是有必要的。 It's very kind of you to help us. 他帮助我们，他真好。 It seemed selfish of him not to give them anything. 他不给他们任何东西，这显得太自私了。 但是，用不定式作主语的句子中还有一个不定式作表语时，不能用It is… to…的句型。另外，这样的句子，不能用动名词作表语。例如： （对）To teach is to learn. （错）It is to learn to teach. （错）To teach is learning. （错）Teaching is to learn. 典型例题 The chair looks rather hard, but in fact it is very comfortable to ___. A. sit B. sit on C. be seat D. be sat on 答案：B. 如果不定式为不及物动词，其后应有必要的介词。当动词与介词连用时，常位于"形容词+动词不定式"结构的末尾。 1.1.1 不定式做主语It's for sb/It's of sb to do sth 这样的句子中，由于表语形容词性质的不同，导致了不定式逻辑主语标志用for或of 的区别。 1）for sb.句型中的形容词一般为表示事物的特征特点，表示客观形式的形容词，如easy, hard, difficult, interesting, impossible等：例如： It's very hard for him to study two languages. 对他来说学两门外语是很难的。

可用虚拟语气的用法总结

虚拟语气的用法总结 语气：语气是动词的一中形式，它表示说话人对某一行为或事情的看法和态度。 虚拟语气表示动作或状态不是客观存在的事实，而是说话人的主观愿望，假设或推测等。如If I were you, I should study English. 一．虚拟语气在条件从句的用法 条件句有两类，一类是真实条件句；一类是非真实条件句，也就是虚拟条件句。 如果假设的情况是有可能发生的，就是真实条件句，谓语要用陈述语气。如If it doesn’t rain tomorrow, we will go to the park. 如果假设的情况是过去或现在都不存在的，或将来不大可能发生的，则是虚拟条件句。如If he had seen you yesterday, he would have asked you about it. 在含有虚拟条件句的复合句中，主句 If her mother had taken the doctor’s advice, she would/might have got well earlier. If it were to rain tomorrow, the match would be canceled. 有时候省略if，采用局部倒装语序。把had /should/were 等动词（不包括行为动词）移到从句的句首。例如： Were it to rain tomorrow, our picnic would be canceled. Had it not been for the storm, we would have arrived in time. Should the earth stop running, what would happen? 二. 错综时间条件句 有时条件从句的动作和主句动作发生的时间不一致，这时需要根据意思采用表示不同时间的动词形式来进行调整。 If she had taken the doctor’s advice, she might still be alive. If I were you, I would have accepted their terms. 三．含蓄条件句

常见的todo与doing

常见的“to do”与“doing”现象 有些动词后既可接to do，也可接doing，它们后接to do与doing在意思上有时有较大的差别。因为它们也是中考的常考点之一，因而我们应该搞清楚它们的区别。 1. stop to do/stop doing sth。 解析：stop to do sth.意为“停下来（正在做的事）去做（另外的）某事”，to do sth.在句中作目的状语。而stop doing sth.意为“停止做（正在做的）某事”。如Mary stopped to speak to me.玛丽停下（手头的工作）来跟我讲话。 When the teacher came in. the students stopped talking.老师进来时，学生们停止讲话。 2. remember to do/remember doing sth 解析：remember to do sth.意为“记住要去做某事”（还没有做）。而remember doing sth.意为“记得（已经）做过某事”如： Please remember to send the letter for me.请记住为我发这封信。 I don’t remember eating such food somewhere.我不记得在哪里吃过这种食物 3. forget to do/forget doing sth 解析：forget to do sth.意为“忘记做某事”（动作还没有发生）。而forget doing sth.意为“忘记做过某事”（动作已发生）。如： Don’t forget to bring your photo here.别忘了把你的相片带来。 I have forgotten giving the book to him.我忘记我已把书给了他。 4. go on to do/go on doing sth 解析：go on to do sth.意为“做完一件事，接着做另外一件事”，两件事之间有可能有某种联系。而go on doing sth.意为“继续做下去”。如： After reading the text, the students went on to do the exercises.学生们读完课文后，接着做练习。 It’s raining hard, but the farmers go on working on the farm.虽然天正下着大雨，但农民们继续在农场干活。 5. try to do/try doing sth 解析：try to do sth.意为“尽力去做某事”，而try doing sth.意为“（用某一种办法）试着去做某事”。如： Try to come a little early next time, please.下次请尽量早点来。 You can try working out the problem in another way.你可以试试用其它的方法解答这道题目。 6. can’t help to do/can’t help doing sth 解析：can’t help to do为动词不定式结构；can’t help doing sth.意为“身不由己地去做某事”或“情不自禁地去做某事。”如： We can’t help to finish it.我们不能帮忙完成此事。 I couldn’t help laughing when I saw her strange face.当我看到她奇怪的脸时，我情不自禁地笑了。 7. hear sb. do/hear sb. doing sth 解析：hear sb. do sth.意为“听见某人做某事”，指听到了这个动作的全过程；hear sb. doing sth.意为“听到某人做某事”，指听到时候，这个动作正在发生。如： I often hear him sing in the classroom.我经常听见他在教室里唱歌。 Do you hear someone knocking at the door?你听见有人在敲门吗？ 应该说明的是：和hear的用法一样的还有see、watch、notice等。

红景天的用法总结

红景天用法汇总 1. 简介 红景天是历朝历代帝王延寿抗衰老的首选之品，也是各朝名医心领神仪的名贵药材。红景天生长在深山大川、悬崖峭壁之上，红景天的足迹往往在人迹罕见的冰川脚下、在白雪覆盖的林海深处，红景天几乎统治了2000公尺雪线生长带，以其生命不衰的顽强生存意识，成为历代皇家御用药材。据《神农本草经》（2200年）记载红景天被列为上品：“主大热生疮、身热烦、邪恶气”。红景天含有具有生物活性的微量元素钙、镁、铁、铅、锌、银、钴、镉、钼、钛、镭等21种。还有人体所需要的十几种氨基酸，其中几种是人体必须的而体内有不能合成的氨基酸，含有丰富的维生素。 2. 食用方法 每日用量：保健3g，治病6g-12g（仅作参考）。 服法：泡开水当茶喝。红景天性寒多服也不会造热生火，且消炎清热，可常年服用。 1）活血消肿：红景天（泡高度白酒） 2）美容润肤：红景天（熬汤汁）+牛奶（敷脸） 3）抗疲劳、抗高原反应：红景天（泡水当茶） 3. 红景天功效1 具有抗缺氧、抗寒冷、抗疲劳、抗微波辐射、抗毒、抗瘟疫、双向调解功能。其具有提高工作效率，补充心脑血氧浓度、抗氧化，延缓人体细胞介质水渗透互换，改善微循环作用，大量增加抗体，提高免疫力，使之延缓衰老，防治老年疾病等功能。 1）抗缺氧作用：红景天可增强人体对缺氧的耐受性，降低氧耗量，同时又加大动脉氧压差，提高氧的利用率，保护肌体脏器官在低氧环境中不受损害，使细胞代谢旺盛。 2）抗疲劳作用：功效类似人参，可明显提高运动员的无氧阀，降低心肌和脑组织的血乳酸值，加快清除疲劳，恢复体力，可提高运动成绩和人们的工作效率，增强记忆能力。 3）双向调节作用：能使“亢进”的功能下降，也能使衰弱的肌体兴奋，从正负两方面使肌体趋向正常。对糖尿病、甲亢、甲低，高低血压病有明显的治疗作用，对高血压患者的降压作用优于复方降压片。 4）活血化淤作用：防止缺氧使血液流变的发生“粘、浓、聚”变化形成血栓，还可用于妇女月经不调、红崩、白带，外用止血消肿等。 5）抗病毒作用：能阻止病毒颗粒的吸附，保护细胞不受病毒的损害，并有一定抑制病毒的作用。 6）抗衰老悦颜健美作用：能消除自由基能力，阻止过氧化反应，抑制此处褐素形成和堆积，从而提高细胞生命力，延缓细胞衰老。 7）抗幅射、抗癌作用：抑制癌细胞，减轻化疗、放疗的副作用。 8）提气升阳，清音利喉作用：慢性咽炎成了歌唱家、教师、公务人员的顽症，泡水常服可消除顽疾。 4. 红景天功效2 红景天可以补气清肺；健脾益气，活血化瘀、益智养心；收涩止血；散瘀消肿。主要针对气虚体弱；病后畏寒；气短乏力；肺热咳嗽；咯血；白带腹泻；跌打损伤；烫火伤；神经症；高原反应等症状。 红景天可以泡水喝，不过这样红景天中的有效成分不能够充分的溶解到水中。相比之下，煎煮会好些，一般先将红景天浸泡3到4个小时，然后用小火煎煮40分钟，让红景天中的有效成分能够溶解出来。当然还有红景天胶囊，提取出来的红景天，更能够容易被人体吸收。.红景天，藏语名：苏罗玛保。在民间被喻为“长生不老草”和“九死还魂草”。盛产于青藏高原，生长在海拔3500—5000米的高寒地段，在缺氧、低温、干燥、狂风、强紫外线辐射的恶劣环境里具有极强的生命力。

虚拟语气用法总结讲课稿

虚拟语气用法总结

虚拟语气用法总结 朱世梅 新时代大学英语中针对虚拟语气的练习题较多,而学生们往往把握不好虚拟语气的正确使用,现将其用法总结如下: 一.虚拟语气在英语里主要用来表达： a. 非真实的情景，不可能发生的事，即某种与事实相反或难以实现的情况，或说话人主观愿望。 b. 与客观事实相反地情景，即强制性虚拟语气，表示建议、命令、劝告这一类的意思上，表示强烈的要求做到、必须做到这样的含义。 c. 虚拟语气的表达形式是通过动词的变化形式表达的，其特点是主从句时态的不一致，而且一般有明显得标志。 二.虚拟语气的考点为： 1.If 句型 (共有三种句型) 非真实条件句: a.与现在的事实相反：从句用一般过去时，主句的谓语用would (could, might) ＋动词原形 If I were Bill Gates, I would not work so hard every day. b.与过去的事实相反：从句用过去完成时，主句的谓语用would (could, might) ＋现在完成时 If I had gone to America when I graduated from middle school, I would have got my PhD degree. c.与将来的事实相反：从句用should (were to，did) + 动词原形，主句的谓语用would (could, might) ＋动词原形 If it should/were to snow tomorrow, I would go skiing.

注意：虚拟条件句的倒装虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略，再把were, should或had 移到从句句首，实行倒装。 Eg: Should it rain, the crops would be saved. =Were it to rain, the crops would be saved. Eg:_____ to do the work, I should do it some other day. A. If were I B. I were C. Were I D. Was I 答案C. 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前, 变成 were, should, had +主语的形式。但在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说 Were I not to do., 而不能说 Weren't I to do. d.混合条件句主句与从句的动作发生在不同的时间，这时主，从句谓语动词的虚拟语气形式因时间不同而不同，这叫做混合条件句。例如：条件句动作发生在过去，主句的动作发生在现在)谓语动词要根据表示的时间进行调整。 Eg: If it had rained last night (过去), it would be very cold today (现在). 2.Wish 句型表达“但愿…，要是…多好”的语气表示与事实相反的情况，或表示将来不太可能实现的愿望。其宾语从句的动词形式为： He wished he hadn't said that. 他希望他没讲那样的话。 I wish it would rain tomorrow. 我希望明天下雨就好了。 Wish to do表达法: Wish sb / sth to do I wish to see the manager. = I want to see the manager. I wish the manager to be informed at once. (= I want the manager to be informed at once.) 3.在强制性语气的宾语从句中的运用即表示建议、命令、劝告、决心等主观色彩的动词 + that + (should) + 动词原形，其中should 经常被省略。这类动词包括： suggest, propose, recommend, demand, order, command, desire, require, insist,
