Question

They were here just now.改为一般疑问句

Answer 1

你好！首先看一下什么是一般疑问句：
一般疑问句是疑问句的一种。它是指用yes（是）或no（否）来回答的句子。其结构是：

　　系动词be/助动词/情态动词+主语+其他成分

　　通常回答为：

　　肯定：Yes，+主语+提问的助动词.

　　否定：No，+主语+提问的助动词+not.

　　如:

　　Are you from Japan﹖

　　Yes I am． / No I'm not．
　1．将陈述句变为一般疑问句时，如句中有be 动词（am/ is/ are）时，可直接将它们提至主语前。如主语为第一人称，应将其改为第二人称。如：

　　I'm in Class 2Grade 1． →

　　Are you in Class 2Grade 1﹖

　　We're watching TV． →

　　Are you watching TV﹖

　　2．陈述句中有情态动词（can、may、must …）时，也可直接将它们提至主语前，即可成为一般疑问句。如：

　　He can swim now． →

　　Can he swim now﹖

　　The children may come with us． → May the children come with us﹖

　　3．陈述句中只有一个实义动词作谓语且其时态为一般现在时，变为一般疑问句时要在句首加do或does 主语后的实义动词用原形。如：

　　I like these animals． →

　　Do you like these animals﹖

　　She wants to go to the movies． → Does she want to go to the movies﹖

　　4．一般疑问句一般读升调(↑)

　　5．一般疑问句有时不用yes或 no 回答。如：

　　Are they in town now﹖

　　I think so.

　　May I sit here﹖

　　Certainly．

　　Does he like soccer﹖

　　Sorry I don't know．

综上所述：将They were here just now.改为一般疑问句为：Were they here just now?

Were they here just now？一般疑问句就是把be动词（am，is，are以及他们过去式），助动词（do/does/did,have/has/had）提前。
