The cat can't Catch the mouse.变否定句和疑问句怎么变？

The cat can't catch the mouse.猫不会抓老鼠。 这句话本来就是否定句。不用变了。 变为疑问句： 否定疑问句： Can't the cat catch the mouse?难道猫不会抓老鼠吗？ 一般疑问句： Can the cat catch the mouse?猫会抓老鼠吗？ 肯定句： The cat can catch the mouse.猫会抓老鼠。 这句话是泛指的。 也就是相当于： A cat can't catch a mouse. 猫不会抓老鼠。 应该说不太合适了。 不过，现在的猫不会抓老鼠也不是怪事。
