譯文

因?yàn)楹苌儆兄髁鞒霭嫖飳?duì)普通非洲裔美國(guó)婦女進(jìn)行深入的專題報(bào)道，所以很少有人知道我們是誰(shuí)，很少有人知道我們的想法以及我們經(jīng)常會(huì)面臨什么樣的問(wèn)題。

點(diǎn)睛

本句的主干是little is known about...。其中because引導(dǎo)的是原因狀語(yǔ)從句；who和兩個(gè)what引導(dǎo)的兩個(gè)從句分別作介詞about的賓語(yǔ)。

in-depth意為“深入的，全面的”。如：

It is time for in-depth reflection on moral. 現(xiàn)在是該對(duì)道德進(jìn)行深入反思的時(shí)候了。

feature意為“特寫(xiě)；專題節(jié)目；特色”。如：

The magazine makes a feature of youth's stories. 該雜志以刊登青少年的故事為特色。

on a regular basis意為“定期地；經(jīng)常地”。如：

I've been saving money on a regular basis for ten years. 10年來(lái)，我始終堅(jiān)持定期存錢(qián)。
