which word? 词语辨析
Many of these words involve making sb believe sth that is not true, but some of them are more disapproving than others. Deceive is probably the worst because people typically deceive friends, relations and others who know and trust them. People mayfeel cheated/betrayed by sb in authority who they trusted to look after their interests. If sbtakes you in , they may do it by acting a part and using words and charm effectively. If sbcheats/fools/tricks/cons you, they may get sth from you and make you feel stupid. However, sb mightfool you just as a joke; and totrick sb is sometimes seen as a clever thing to do, if the person being tricked is seen as a bad person who deserves it.以上各词多含使人将假话信以为真之义，但其中有些词贬义较另一些词强。deceive 大概贬义最强，主要指欺骗朋友、亲戚和其他认识和信任自己的人。相信掌权者能够顾全自己利益却遭欺骗可用 feel cheated/betrayed。通过装腔作势或花言巧语等骗人用 take sb in。哄骗、愚弄他人用 cheat/fool/trick/con。只为开玩笑可用 fool。如果被戏弄者是应该受到惩罚的坏人，可用 trick，表示计谋巧妙。
