再贴几道语法题。 (from PP-Test 1), 谢谢谢谢
填空
4. Perhaps the most significant postwar trend was the decentralization of cities throughout the United States, (a phenomenon that accelerated) when massive highway-building programs permitted greater suburban growth.
这句句子的结构是怎样的呢?a phenomenon 是同位语,后面又跟个怪怪的that accelerated?
改错
97. The pericardium, a double-layered sac, (it surrounds) the heart (and) the (large vessels) entering and (leaving) the heart.
选A没错,删去it. 但是后面的半句and之后的怎么没有谓语呀,直接用-ing??
131. (As sweeteners), there is very (small) difference between honey and sucrose, (although) the former des contain minimal (quantities) of vitamins, minerals, and amino acids.
答案是B, 改成little.我觉得两种都可以地说。大家觉得呢?D有没有问题?
