Last week, I did some exercises at The Bedford Handbook.　That is very helpful for international student　to learn　the gummer for writing. After this exercises,　I think there are three parts that　are very helpful for me.　The first one is Active　vs. Be verbs, That could let me know how to use Be verb, and what kind of different between active and be verbs. For example, Be Verb: Sudden loss of weight can be an indicator of many serious health problems. Active: Sudden loss of weight can indicate many serious health problems. The second one is Active vs. Passive verbs; this exercise cloud let me know how to use Active and Passive verbs. When I want to write more powerful and effective sentences, then I can use the active verbs form, otherwise, I can use passive verbs. The last one that I learned is active verbs. That was the one I never use is before when I wrote many paper, but now, I know how to use it. For example, Active: peter cleans the room every day. Passive: The room is cleaned by peter every day.
After all, this is a nice exerises, and it is very helpful, i learned a lot from it.
