<h2>现在完成时的延续性动词和非延续性动词</h2>
<p><strong>1. 延续性动词</strong></p>
<p>延续性动词指的是那些可以持续一段时间的动作或状态。在现在完成时中,我们可以用这些动词来描述一个从过去开始并一直持续到现在的动作或状态。</p>
<p><strong>例子:</strong></p>
<ul>
<li>I have lived in Beijing for five years.</li>
<li>She has worked at this company since 2015.</li>
</ul>
<p><strong>2. 非延续性动词</strong></p>
<p>非延续性动词通常表示瞬间动作或状态,不能用来描述一段持续的时间。在现在完成时中,我们通常会用延续性动词或短语来替换它们。</p>
<p><strong>例子:</strong></p>
<ul>
<li>He bought a car. (非延续性)</li>
<li>He has had a car for two years. (延续性)</li>
</ul>
<p><strong>3. 注意事项</strong></p>
<p>当使用非延续性动词时,我们不能直接与表示时间段的介词短语连用。例如,不能说 "I have joined the club for three years",而应该说 "I have been a member of the club for three years"。</p>
