五年级英语语法知识汇总 一、词类： 1、名词 这里强调两点：不可数名词都默认为单数，所以总是用is 名词复数如何加后缀：
2、人称代词和物主代词 人称代词：有主格和宾格之分。一般动词前用主格，动词后用宾格。 3、指示代词 4、冠词 有a、an、the。a和an的区别：an用于元音音素（一般就是元音字母a、e、
i、o、u）前，a用于辅音音素前。 二、否定句： be动词（am、is、are）+not、 情态动词can+ not、 助动词（do、does）+ not 如何将一个肯定的陈述句改为否定句： 1、看句中有无be动词，如有，直接在be动词后+ not。 2、看句中有无情态动词，如有，直接在情态动词后+ not。 3、如上述二者都没有，就应用助动词+ not。分四个步骤： （1）肯定陈述句中本来是没有助动词的，要加上去，位置在主语（某人或某物）后，动词前。 （2）确定助动词用do、does，根据句中动词，动词是原形的助动词就用do，动词是第三人称单数的助动词就用does， （3）在助动词后加not。 （4）原句中动词假如发生变化就要恢复成原形。 强调一点，有some的要考虑是否要用any。 三、一般疑问句。 如何将一个肯定的陈述句改为一般疑问句： 1、看句中有无be动词，如有，把be动词提到句首即可。 2、看句中有无情态动词，如有，把情态动词提到句首即可。 3、如上述二者都没有，就应把助动提到句首。分四个步骤： （1）肯定陈述句中本来是没有助动词的，要加上去，位置在主语（某人或
某物）后，动词前。 （2）确定助动词用do还是does，根据句中动词，动词是原形的助动词就用do，动词是第三人称单数的助动词就用does （3）把助动词后提到句首。 （4）原句中动词假如发生变化就要恢复成原形。 强调一点，有some的要考虑是否要用any。 四、特殊疑问句。 表示疑问，有疑问词（在开头），回答有很多种可能。 常用疑问词： 五、时态 1、一般现在时
倒装句 英语句子的主语通常位于谓语动词之前，这种语序被称为正常语序。但有时出于强调或某种特殊的语法结构的需要，需要将谓语动词放在主语之前，这种语序则叫倒装语序。按倒装的形式，倒装可分为两类，一是完全倒装，二是部分倒装。完全倒装是指全部谓语放在主语之前，部分倒装是指只把助动词、情态动词或be动词放在主语之前，谓语的主体部分仍在主语之后。 一、完全倒装 1. 用于there be 句型。 例：There are many students in the classroom. 原句自然顺序是：Many students are there in the classroom. ★2. 表示地点的here和 there位于句首时，其后用完全倒装形式。这类倒装句的谓语通常是动词be和come, go等表示移动或动态的不及物动词，以及stand, lie, live等表示状态的动词(表示存在)。 例：Here comes the bus. 公共汽车来了。 There goes the last train. 最后一班火车开走了。 There stood a desk against the wall. 靠墙放着一张书桌。 注意：若主语为人称代词，则不倒装。如： Here you are. 这就是你要的东西。（给你。） Here it comes. 它来了。 ★3. 表示方向的副词away, down, in, off, out, over, round, up 等位于句首时，其后用完全倒装语序。这类倒装句的谓语通常表示动态的不及物动词。 Out rushed the puppy. 小狗冲了出去。 Away went the girl. 那个女孩走远了。 Down came the rain and up went the umbrellas. 下雨了，伞都撑起来了。 注：若主语为人称代词，则不能用倒装。如： In he comes. 他走了进来。 Down it came. 它掉了下来。 ★4. 表示时间或顺序的副词now, then 等位于句首时，其后用完全倒装语序。这类倒装句的谓语通常表示动态的不及物动词。如：

高中英语倒装句 倒装句分为全部倒装和部分倒装 1 全部倒装 全部倒装是只将句子中的谓语动词全部置于主语之前。此结构通常只用于一般现在时和一般过去时。常见的结构有： 1）here, there, now, then, thus等副词置于句首, 谓语动词常用be, come, go, lie, run等表示来去或状态的动词。 Then came the chairman. 那时总裁来了。 Here is your letter. 你的信。 2）表示运动方向的副词或地点状语置于句首，谓语表示运动的动词。 Out rushed a missile from under the bomber. 轰炸机肚底下窜出一枚导弹。 Ahead sat an old woman. 前面坐着一个老妪。 注意：上述全部倒装的句型结构的主语必须是名词，如果主语是人称代词则不能完全倒装。 Here he comes. 他来了。 Away they went. 他们走开了。 2 部分倒装 部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句子的谓语没有助动词或情态动词，则需添加助动词do, does或did，并将其置于主语之前。 1.句首为否定或半否定的词语，如no, not, never, seldom, little, hardly, at no time决不, in no way, not until…等。 Never have I seen such a performance. 从未见过如此糟糕的表演。 Nowhere will you find the answer to this question. 无论如何你不会找到这个问题的答案的。 Not until the child fell asleep did the mother leave the room. 母亲一直到孩子入睡后离开房间。 2.当Not until引出主从复合句，主句倒装，从句不倒装。注意：如否定词不在句首不倒装。 I have never seen such a performance. ---never have I seen such a performance. The mother didn\'t leave the room until the child fell asleep. ---not until the child fell asleep the mother did leave the room. 2）Not until the early years of the 19th century ___ what heat is. A. man did know B. man know C. didn\'t man know D. did man know 答案D.看到Not until…的句型，我们知道为一倒装句，答案在C，D 中选一个。 改写为正常语序为，Man did not know what heat is until the early years of the 19th. 现在将not提前，后面就不能再用否定了,否则意思就变了。 3.以否定词开头作部分倒装 如Not only…but also, Hardly/Scarcely…when, No sooner…than等，要倒装。 Not only did he refuse the gift, he also severely criticized the sender. 他没有收下礼物，还狠狠批评了送礼的人。 Hardly had she gone out when a student came to visit her. 她刚出门，就有个学生来访。 No sooner had she gone out than a student came to visit her. 她刚出门，就有个学生来访。 4.so, neither, nor作部分倒装 用这些词表示\"也\"、\"也不\" 的句子要部分倒装。 Tom can speak French. So can Jack. 汤姆会讲法语，杰克也会。 If you won\'t go, neither will I.你不去，我也不去。 注意：当so引出的句子用以对上文内容加以证实或肯定时，不可用倒装结构。意为\"的确如此\"。 Tom asked me to go to play football and so I did. 汤姆邀我去踢球，我去了。 ---It\'s raining hard.---So it is. 雨下得真大。是呀。 5. only在句首倒装的情况。 Only in this way, can you learn English well. 只有这样，你才能学好英语。 Only after being asked three times did he come to the meeting. 叫了三次，他才来参加会议。
小学五年级英语必须掌握的一些英语语法知识 一、时态 1、一般现在时： 概念：经常、反复发生的动作或行为及现在的某种状况。 时间状语：often（经常），usually（通常），always（总是），sometimes（有时），every week（day，year，month．．．），on Sundays，… 基本结构：①be动词；②行为动词 否定形式：①am ／is ／are ＋not；②此时态的谓语动词若为行为动词，则在其前加don't，如主语为第三人称单数，则用doesn't，同时还原行为动词。 一般疑问句：①把be动词放于句首；②用助动词 do提问，如主语为第三人称单数，则用does，同时，还原行为动词。 2、现在进行时： 概念：表示现阶段或说话时正在进行的动作及行为。 时间状语：now，look，listen，… 基本结构：am／is／are ＋doing 否定形式：am／is／are ＋not＋doing 一般疑问句：把be动词放在句首 二、第三人称单数
一般现在时的肯定句中，主语为第三人称单数的动词变化主要体现在词尾的变化上，其规律大体有三点： 1. 一般情况下，直接在动词词尾+s ，例如：get→gets; take→takes 2. 以s, sh, ch, x, o 结尾的动词，在词尾+ es，例如：teach→ teaches; wash→washes; go→goes 3. 以辅音字母+ y 结尾的动词，变y 为i，再+ es，如：study→ studies; try→tries 除上述规律外，还应注意下面三点： 1. 动词 have ，遇到主语是第三人称单数时，要用 has；动词 be 的第三人称单数形式是is。 2. 含有动词第三人称单数形式的句子变否定句时，要用doesn't + 动词原形，如： He goes to school at six in the morning. (变否定句)→ He doesn't go to school at six in the morning. 3. 对含有动词第三人称单数形式的句子提问时，要用助动词 does，如： She goes home at five every day. (对划线部分提问)→ When / What time does she go home every day? 三、名词复数 1、构成方法及读音规则
