在开始动词时态课程之前，去了解并非所有英语动词都相同，这非常重要。英语动词分为三组：普通动词、非连续动词和混合动词。
Before you begin the verb tense lessons, it is extremely important to understand that NOT all English verbs are the same. English verbs are divided into three groups: normal verbs, non-continuous verbs, and mixed verbs.
第一组 普通动词（Normal Verbs）
Most verbs are "normal verbs." These verbs are usually physical actions which you can see somebody doing. These verbs can be used in all tenses.
大多数动词是“普通动词”。这些动词通常是您可以看到某人正在做的身体动作。这些动词可以用于所有时态。
普通动词 Normal Verbs
to run, to walk, to eat, to fly, to go, to say, to touch, etc.
Examples:
I eat dinner every day.
I am eating dinner now.
第二组 非连续动词 Non-Continuous Verbs
第二组，称为“非连续动词”，较小。这些动词通常是你看不到有人在做的事情。这些动词很少用于连续时态。它们包括：
The second group, called "non-continuous verbs," is smaller. These verbs are usually things you cannot see somebody doing. These verbs are rarely used in continuous tenses. They include:
抽象动词 Abstract Verbs
to be, to want, to cost, to seem, to need, to care, to contain, to owe, to exist...
占有动词 Possession Verbs
to possess, to own, to belong...
情感动词 Emotion Verbs
to like, to love, to hate, to dislike, to fear, to envy, to mind...
Examples:
不正确 He is needing help now.
正确 He needs help now.
不正确 He is wanting a drink now.
正确 He wants a drink now.
第三组 混合动词（Mixed Verbs）
第三组，称为“混合动词”，是最小的组。 这些动词有不止一个意思。 在某种程度上，每个含义都是一个独特的动词。 有些含义表现得像“非连续动词”，而其他含义表现得像“正常动词”。
The third group, called "mixed verbs," is the smallest group. These verbs have more than one meaning. In a way, each meaning is a unique verb. Some meanings behave like "non-continuous verbs," while other meanings behave like "normal verbs."
混合动词 Mixed Verbs
to appear, to feel, to have, to hear, to look, to see, to weigh...
