261. Because few mainstream publications have done in-depth features on regular African-American women, little is known about who we are, what we think and what we face on a regular basis.
译文因为很少有主流出版物对普通非洲裔美国妇女进行深入的专题报道，所以很少有人知道我们是谁，很少有人知道我们的想法以及我们经常会面临什么样的问题。
点睛本句的主干是little is known about...。其中because引导的是原因状语从句；who和两个what引导的两个从句分别作介词about的宾语。
in-depth意为“深入的，全面的”。如：
It is time for in-depth reflection on moral. 现在是该对道德进行深入反思的时候了。
feature意为“特写；专题节目；特色”。如：
The magazine makes a feature of youth's stories. 该杂志以刊登青少年的故事为特色。
on a regular basis意为“定期地；经常地”。如：
I've been saving money on a regular basis for ten years. 10年来，我始终坚持定期存钱。
考点归纳与basis有关的短语还有：
on a fifty-fifty basis对等地（平分）
Costs are to be shared on a fifty-fifty basis between the manufacturer and distributor. 费用由厂商和批发商均摊。
provide a...basis for 为……提供……根据
Religion should not provide the basis for ethics. 宗教不应该为道德规范提供依据。
