Question

Seeing from the top of the hill, and you'll find the city more beautiful

1.Seeing from the top of the hill, and you'll find the city more beautiful

2.Study harder,and youwill catch up with the others in your class.
这两个句子的see和study为什么一个用现在分词一个用原型？

Answer 1

第一句是现在分词作条件状语， 注意把and 去掉！！！
第二句是个常见的句型：
祈使句（动词原形开头， 表条件） + and + 陈述句（一般用will + 动词原形）
Work hard , and you'll catch up with him.
=If you work hard, you'll catch up with him
如果表否定， 中间用or
Hurry up, or you 'll miss the train.
=If you don't hurry, you'll miss the train

也就是说，第一个句子应该是Seeing from the top of the hill, you'll find the city more beautiful？确定？

追答

我是教英语的。 分词短语和句子之间不可能有并列关系的。所以不要and

Answer 2

1 中see做动名词 所以用seeing
2中study hard 是祈使句 所以直接用原型
