He saw some birds in the tree 改成一般疑问句和对划线部分提问 划线部分是：some birds 怎么改
一般疑问句：Did he see any birds in the tree?
划线提问：What did he see in the tree?
注意：
1、some在否定句和疑问句中要改成any..
2、划线提问的要领：划线提问用“替换法”,即用一个特殊疑问词替换掉划线部分.以He saw some birds in the tree 为例：
如果划线部分是he,he指人,而且是主语,所以用 who替换,说成Who saw some birds in the tree.
如果划线部分是some birds,some birds指物,就用what替换.
如果划线部分是in the tree,in the tree是地点状语,就用where替换,说成Where did he see any birds?
另外,时间状语用when替换,原因状语用why替换,方式或状态用how替换,数量的多少用how many或how much替换,价格用how much替换,等等.如：
He is very good.如果划线部分是very good,就问How is he?
