一般疑问句还有下列特点：1、以be动词、助动词或情态动词开头；例：Is your father a teacher? Does Jack like animals? Can Lucy speak English?2、往往读升调；3、译成汉语，都可以带上“吗”，例如上面三句可分别译为：你父亲是老师吗？杰克喜欢动物吗？露丝会说英语吗？二、如何将陈述句变成一般疑问句？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），2)有，直接将它们提至主语前，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?3)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：如果谓语动词是原形，则借do；如果谓语动词是一般现在时第三人称单数形式，则借does；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。
