I've been reading some books and confusing about how to use "verb plus "ing" in the beginning of a sentence". Here
Here are some examples: 1.a large crowd was still huddled around Bird, "blocking" him from site. 2.He's going to be okay, Mrs.Banks interrupted, "seeing" the frightened looks on her son's faces. 3.You don't look so great, Greg blurted out, "stepping" up cautiously to the bed. 4.Shari and Greg, "running" side by side at full speed, "reached" him together
- A large crowd was still huddled around Bird, blocking him from site. 2. He's going to be okay, Mrs.Banks interrupted, seeing the frightened looks on her son's faces. 3. You don't look so great, Greg blurted out, stepping up cautiously to the bed.
4. Shari and Greg, "running" side by side at full speed, reached him together
In the fourth example, reach is also a verb, why couldn't it be a verb+ing form ? If there's any rules to learn how to identify the difference ?
