一、There be 句型是干什么用的 汉语说"桌上有一本书"，英语不能说 "A book is on the desk" 吗？语法上可以，但更自然、更常用的说法是 There is a book on the desk. There be 句型的核心意思是"某处存在某物"，它回答的是"有什么"，而不是"谁做了什么"。 基本结构：There is/are + 名词 + 地点/时间状语。 用 is 还是 are，只看紧跟其后的那个名词： 可数名词单数或不可数名词 → There is。例：There is a pen on the desk. There is some water in the bottle. 可数名词复数 → There are。例：There are two books in the bag. There are many trees in the park. 五年级上册第五单元 There is a big bed 和第六单元 In a nature park 都在反复练这个句型，可见它是本册的重点中的重点。
二、就近原则：最容易丢分的一条 当一个句子里出现两样或更多东西时，be 动词跟着离它最近的那个名词变。 There is a pen and two books on the desk.（最近的是 a pen，用 is） There are two books and a pen on the desk.（最近的是 two books，用 are） 注意：课本里出现过 "There is a bed, a desk and two chairs in my room." 这类句子，绝不能说成 There are a bed...。做题时先数"be 动词后面的第一个名词"，这是判断的唯一标准。
三、否定句：加 not，some 变 any 否定形式直接在 be 后面加 not： There is not (isn't) a cat under the table. There are not (aren't) any pandas in this zoo. 规律：肯定句里的 some 在否定句和疑问句中通常变成 any。 There is some milk in the glass. → There isn't any milk in the glass. There are some flowers in the garden. → Are there any flowers in the garden? 但要注意两个例外：表示请求或希望对方肯定回答时，疑问句仍用 some，如 Would you like some tea?；以及 some 修饰可数名词单数时表示"某个"，如 Some boy is waiting for you.
四、一般疑问句：be 提前，回答用 there 变疑问句时，把 is/are 提到 there 前面： Is there a library in your school? — Yes, there is. / No, there isn't. Are there any birds in the tree? — Yes, there are. / No, there aren't. 答语里必须用 there，不能回答 Yes, it is. 或 Yes, they are. 这是选择题的高频陷阱。
五、特殊疑问句：对数量提问 对可数名词的数量提问，用 How many + 复数名词 + are there + 地点？ How many students are there in your class? — There are forty-five. 对不可数名词的量提问，用 How much + 不可数名词 + is there？ How much water is there in the bottle? — There is a little. 另外两个常考句型： What's + 地点？用来问那里有什么。What's in the nature park? — There is a small river and some hills. How many ... are there? 的答语可以用 There are + 数字，也可以直接说数字。
六、情景对话示例（In a nature park） Amy: Look! This is a nature park. Mike: Wow! Is there a river in the park? Amy: Yes, there is. There is a long river in the middle of the park. Mike: Are there any fish in it? Amy: Yes, there are. There are many fish. And there are some ducks, too. Mike: How many ducks are there? Amy: There are about twenty. Look, there is a small boat near the bridge. Mike: Great! Let's go and have a look. 这段对话把 is/are、any、How many 三个考点全用上了，建议整段背下来，口语和写作都能直接套用。
七、四个高频易错点 易错点1：there be 与 have/has 混用。There is a book on the desk.（正确，表示"存在"）I have a book.（正确，表示"拥有"）。不能说 There has a book，也不能说 I am a book。 易错点2：be 动词与名词数不一致。There are a pen...（错），There is two books...（错）。 易错点3：否定句忘变 any。There aren't some chairs.（错），应为 any。 易错点4：答语用错代词。Are there any apples? — Yes, they are.（错），应为 Yes, there are. 还有一个小细节：There be 句型后面接地点状语时，地点状语一般放在句末；如果地点状语较长，也可以放句首，如 In the park there are many trees.
八、分层练习 一、用 is 或 are 填空 1. There ___ a big bed in my room. 2. There ___ some apples on the plate. 3. There ___ a desk and two chairs in the study. 4. There ___ two chairs and a desk in the study. （答案：is, are, is, are）
二、按要求改写句子 1. There is a park near my home.（改为否定句） （There isn't a park near my home.） 2. There are some flowers in the garden.（改为一般疑问句并作肯定回答） （Are there any flowers in the garden? Yes, there are.） 3. There are thirty students in the classroom.（对 thirty 提问） （How many students are there in the classroom?）
三、翻译句子 1. 你的书包里有一些书吗？是的，有。 （Are there any books in your schoolbag? Yes, there are.） 2. 山上有许多树，但是没有花。 （There are many trees on the mountain, but there aren't any flowers.）
四、小作文（5句左右） 用 There is/There are 描述你的卧室，至少写两样物品和一处位置。 （示例：There is a bed in my room. There is a desk near the window. There are two chairs and a bookshelf in it. There is a computer on the desk. There are some pictures on the wall. I like my room very much.） 把 there be 句型和方位介词 on/in/under/near/behind 搭配起来用，描述房间、教室、公园的作文就再也不会写不出来了。
