专四的问题是不能请教外国人的，因为外国人也会被误导。以下是我请教老美的结果，人家没有一道做对的...

第一道他选A，看了答案分析道：hmmmm, A only adds "having been" to the answer, making it past continuose tense... so i guess they think that trained is better, because it is past perfect tense, meaning that only after training will they be without fear. so b is best i suppose

第二道他选B，看了答案分析道："of" works, but it means that she thought he first plan was better than someother plan that we don't know about. "than" means she thought of a new solution that is better than her first one (the only solution we are introduced to!) grrrrrr
问题是我现在需要一个应试的，Chinglish的答案。
btw，关于think better of,大家看看下面这个，what do u think? http://www.baidu.com/s?lm=0&si=&rn=10&ie=gb2312&ct=1048576&wd=think+better+of&tn=baidu
