105. Some hoped his rise to prominence would have a big impact on white Americans, too, challenging those who still harbour racist sentiments.

译文　

一些人希望他的崭露头角会对美国白人有巨大的影响，同时向那些仍旧心怀种族主义情绪的人发起挑战。

点睛

本句的主干是Some hoped...。his rise to prominence would have a big impact on white Americans是hoped的宾语从句，其主干为rise would have a (big) impact。too为句中的插入语；challenging those...是句子的伴随状语，其中who引导的是those的定语从句。
prominence的意思是“重要，突出，出名”，表示“崭露头角”还可用动词短语come to prominence或gain prominence。如：
He first came to prominence in one competition. 他最初在一次比赛中崭露头角。
have an impact on的意思是“对……产生影响”。如：
His speech had no impact on his kids. 他的话丝毫没有影响到他的孩子们。
harbour此处意为“怀有，心怀（尤指负面的感情或想法）”。如：
They may harbour some sort of grudge against you. 他们可能对你怀恨在心。

考点归纳　

宾语从句中动词的时态往往受到主句谓语时态的制约，即“时态呼应”。当主句谓语为过去时的时候，从句谓语的改变方式一般如下：
一般现在时改为一般过去时。如：
I didn't know where you lived. 我不知道你住在哪里。
现在进行时改为过去进行时。如：
I was glad they were doing well. 他们做得不错，我很高兴。
现在完成时改为过去完成时。如：
I heard you had won a scholarship. 我听说你得奖学金了。
一般将来时改为过去将来时。如：
She wasn't sure if you would accept the offer. 她不确定你是否会接受这份工作。
