在英语作文中举例子的方法如下：

使用常见的举例句式

For example：例如，我在校对方面有问题。

For instance：举例来说，我讨厌清洁厨房，但我还是因为喜欢看到一个整洁的厨房而做了。

Such as：比如，我喜欢诸如茶和汽水之类的饮料。

Take...for example：让我以爱迪生为例。

提供具体细节

在举例时，尽量提供具体的细节，这样可以使例子更加生动和可信。例如：“First, ads disturb our life. Surely, we all have the experience that an insert of the information about a product often interrupts our pleasure of watching an exciting film on T.V, which makes us so annoyed that sometimes we have the impulse to call the T.V station to make a complaint.”

使用个人经历

描述自己或亲友的经历可以使例子更加真实和有说服力。例如：“I have problems with proofreading. For example, I often miss small errors when I am writing a long essay.”

引用权威人物或事件

引用知名人物或历史事件可以增强例子的权威性。例如：“Raoul Wallenberg was a young Swedish aristocrat. In 1944 he left the safety of his country and entered Budapest. Over the next year he outwitted the Nazis and saved as many as 100,000 Jews （he was not himself Jewish） from the death camps.”

对比例子

通过对比不同的例子，可以更清晰地说明观点。例如：“My best friend and I have different personalities. While she is outgoing and sociable, I am more reserved and prefer to spend time alone.”

结合个人感受

在例子中加入个人的感受和想法，可以使例子更加贴近读者的情感。例如：“Whenever I hear my favorite song, I cannot but feel excited and energized.”

通过以上方法，可以使英语作文中的例子更加生动、具体和有说服力。
