對于不經常使用的內置超鏈接可以加上下劃線。

It makes the link stand out a little more than colour alone.

通過對超鏈接使用下劃線（與僅對超鏈接進行顏色變化）更能起到突出超鏈接的作用。

In this example, the underlining works well to distinguish article titles from the sub-title.

在這個案例中，下劃線可以清楚地區分主標題和二級標題。

I think underlining becomes unhelpful when there are numerous inline links in paragraphs, in lists of links, and when there are lots of sets of links on a page.

假如段落中、鏈接列表中或頁面中的超鏈接過多，那對這些鏈接使用下劃線將起不到任何突出作用。

Here are a couple of examples of collections of hyperlinks, showing the original (underlined) and the same with underlines removed.

下面兩組超鏈接效果的對比。左邊的超鏈接包含下劃線，右邊則不包含下劃線，具體如下：

Notice how it's quicker and easier to read the non-underlined blocks of text.

請注重：假如像上面這樣的鏈接列表，那么不使用下劃線將更有助于快速、簡便地閱讀。

In this second example, I have also adjusted the line spacing to make the related words clearer.

在第二個案例中，我還調整了單詞之間的間距以使其看上去更加清楚。
