注意：1 把陈述句改为一般疑问句时,要特别注意在需要的地方改变人称.
\x09 2 把陈述句该为一般疑问句时,如果句中有some,要把some改为any.但是在表示请求的句子中,却不要做这种改动,因为这表示问话的人希望得到一个肯定的答复.
\x09 3 把陈述句改为一般疑问句时,不要改动时态.
\x09 4 把陈述句改为一般疑问句时,如果句中有do或have以及其相关形式,要注意看do和have是否助动词,如果是实意动词则需要再加适合的助动词.

英语中一般都是把陈序句该疑问句。
就是把谓语动词提前。如果是有时态的话，就把该时态的助动词放在句首，实意动词位置不变。
比如 Is this his book？
Has he done the project?
