考研英语二卷中的一个问题 求解答 谢谢

In this way,many small language could sustain their cultural and linguistic integrity,rather than yield to the homogenizing forces.
yield to是和sustain一样的并列结构，yield不是than的宾语

In this way,many small languages（得加个s) could sustain their cultural and linguistic integrity,rather than yield to the homogenizing forces.
这里结构是：could do...rather than do 后面动词原形，表示：而不是……

类似结构：would do...rather than do
通过这种方式，许多小语种可以维持其文化和语言的完整性，而不是屈服于均化的力量。
I would stay here rather than leave.
如果是并列的选择是可能用doing或名词的。
