B 选项 没有谓语动词了~E选项 是倒装 看后面的 主语 应该是~the rate at which trees grow
。。应该是单数主语 所以 没错~作者: nkzhengduo 时间: 2011-5-6 22:57
E选项是倒装，因为among介词结构提前所以要倒装，正常语序应该是 The rate at which trees grow is believed to be among the surest indications on Earth of sunspot cycles 真正的主语是rate 所以 is 没有问题作者: lala974 时间: 2011-6-30 04:24
