SC：（参考意义不大）
我做了一道考了单复数的，是a company balabala its balabla，就是要从这个its去推定前面a company的单复数的，its这个位置没划线的，大家细心点；选项似乎有companies这个选项；
最后一点小感想：
1.我的sc开窍全赖Ron的视频，他真讲得很好，他很多思路都很对，包括对sc考点的分类，也是最得我心的；（但感觉这次sc没考好，也是哭了）
People don't want to hear this——it's a blow to the ego——but almost 100% of problems rely on one of the following 6 types of errors:
• Parallelism
• S-V agreement
• Pronoun problems
• Placement (when words are moved around)
• Choice between/among different kinds of modifiers
• Overall sentence integrity (is it a sentence? vs. a fragment/run-on)
