（此条戒律请背 10遍！！！）

believe（相信），doubt（怀疑），see（看见），hear（听见） ，know（知道），understand （理解），belong（属于），think（认为），consider（认为），feel（觉得），look（看起来）， seem（看上去），show（显示），mind（介意），have（有），sound（听起来），taste（尝起来）， require（要求），possess（拥有），care（关心），like（喜欢），hate（讨厌），love（喜爱）， detest（憎恨），desire（意欲）

【简单记忆】

● 永远不要说I'm believing...或He is seeing a house. 再简单一点说，这些动词后面不要随意加-ing.

● 可怕的是：我们在写作及口语中常犯此类大错！

● 注意：have a party / think about可以用进行时，因为这里have意为“举行”；think意为“考虑”。
