Is the basketball more interesting than the football?
Hai Nan is hotter than Wu Han{改为一般疑问句}
Is Hai Nan hotter than Wu Han?

不含be动词的句子,变一般疑问句怎么变？
首先be动词：am is are——过去式 was were ——过去分词been变一般疑问句，把be动词提前到句首，句号变问号变否定句 在be动词后面加not 可以写成缩写 ：isn't aren'teg：陈述句：He is at home.否定句：He isn't at home.一般疑问句：Is he at home ?
含有动词can的句子如何变一般疑问句？
我告诉你一个最简单的规律，转换句型时数动词的个数。
一. 1个动词的：一个动词的不是be就是行为动词。
方法是：有be变be真容易，行为动词要小心，do和does来帮助，否定疑问别忘记。
有动词be你直接提前到句首就变成一般疑问句了。
如：He is poor.-- Is he poor?如果是行为动词你就看它的形式：原形的用do，带s的用does，过去式的用did提前，因为do有前面已经代表动词的时态和形式了，后面那个行为动词就全部用原形了。
如：They come from China. --Do they come from China?He lives here. -- Does he live here?He bought a new car. -- Did he buy a new car?单个动词的就这两种情况，不管第几人称，按这个规律全部搞定。
二.两个或两个以上的动词：这个就更简单了。
只要把第一个动词提到句首就变成一般疑问句了。
如：He is studying. -- Is he studying?He will study. -- Will he study?He has done it. -- Has he done it?He will be waiting for you. -- Will he be waiting for you?不管第几人称，全部适用。
最后加一句：其实学习英语就在于方法。
方法对头，把复杂问题简单化之后，随便练习一下，就ok啦！

陈述句变一般疑问句
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：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。
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,在助动词后加not。
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。

陈述句变为一般疑问句
是把陈述句改成一般疑问句吗？如下：一、要将陈述句变成一般疑问句，可以遵循下列步骤：1.看句中有没有be动词（am、is、 are、 was、 were）、助动词（do、does、did、 have、 had）或情态动词（can、must、will、may等），如果有，将其提到句首，句末打上问号即可。
例：It was rainy yesterday.→Was it rainy yesterday?Tom's father can play the piano.→Can Tom's father play the piano?I have finished my homework.→Have you finished your homework?2.如果句中没有be动词、助动词或情态动词，则根据谓语动词的形式借助do的相应形式放在句首。
具体方法是：①如果谓语动词是原形，则借do;②如果谓语动词是一般现在时第三人称单数形式，则借does;③如果谓语动词是过去式，则借did.需要注意的是，借does或did后，原句的谓语动词要变回原形。
例：They go to school by bike.→Do they go to school by bike?Bill gets up at 6:30 every day.→Does bill gets up at 6:30 every day?The students saw a film yesterday.→Did the students see a film yesterday?二、陈述句变一般疑问句应注意的事项陈述句变成一般疑问句除了遵循上述规则以外，还应注意下列几点：1.如果陈述句中有第一人称，则变问句时最好要变为第二人称。
例：I usually have lunch at school.→Do you usually have lunch at school?My father is playing soccer.→Is your father playing soccer?2.如果陈述句中有some， 则变问句时往往要变成any 。
例： There is some water on the playground.→Is there any water on the playground?3.复合句变一般疑问句通常只变主句，从句不变。
例：I know he comes from Canada.→Do you know he comes from Canada?4.如果句中含有实义动词have且表示“有”时，除借do外，也可将其直接提到句首。
例：I have some friends in America.→Have you any friends in America?/Do you have any friends in America?
