133. Phonological structure encodes (speak) sounds as a (sequence) of vocal tract configuration--(successive) positions of the larynx, jaw, (lips), tongue, and velarn.

这题选A，不知道该怎么改？

140. It (is said) that no potential frontier has (such) fired the imagination or challenged the (ingenuity) of humankind (as has) space.

这题的B，such该怎么改？

142. (Through) his painting, Edward hopper depicted the isolation, (lonely), and lack of (variety) of the daily life (of) small--town America.

这题选B，但C的variety为什么不要改为复数啊？
