50:正确的表达 According to some analysts, the gains in the stock market reflect growing confidence that the economy will avoid the recession that many had feared earlier in the year and instead come in for a “soft landing,” followed by a gradual increase in business activity.
考的用and instead 连接的带转折的平行结构. the economy will avoid the recession....and instead (will) come in for a "soft landing" 用and连接平行结构,instead表达略带转折的逻辑含义。
BD: 少了连接句子的and,同时没有平行结构
57:if we invert this construction(用it做形式主语)
B: That educators have not anticipated the impact of microcomputer technology can hardly be said to be at fault
-----> It can hardly be said to be at fault that educators have not anticipated the impact of microcomputer technology.
这样我们可以比较明白的感觉到it can hardly be said to be at fault这个表达is awkward and unclear. be at fault 的是人,而不是that 所引导的整个句子。
而B中是将整个that所引导的句子跟上main verb(can hardly be said),不仅没有清晰表达出who are at fault,同时还有logical problem.
