英语高手帮我解决几道语法题吧！

    1。It is essential that he___in extracurricular activities。 rticipate rticipates C。
  will participate all participate \\\\ A participate It is essential that 是虚拟语气句式，that 的从句中 用 should + 动词原形，而should 可省略。
     2。Research findings show we spend about two hours dreaming every night,no matter what we__during the day。
   ould have done B。would have done y have done st have done \\\\\\\ may have done 研究发现显示，每天夜里我们花大约2个小时做梦，不论我们在白天期间可能做了什么。
     只有选 C 句子的意思才是通顺的。 3。It was impossible to avoid___by the stormy weather。 be much affected ing much affected C。
  having much affected have been much affected \\\\\B being much affected avoid 后 接动名词，不能接不定式。  所以 A D 错误。
  而C是主动句式，不是被动句式，不符合句子的意思。 4。Although he knew little about the large amounts of work done in the field,he succeeded___other more well-informed experimenters failed。
     A。which at C。what D。where \\\\\\\ D where 虽然他对这个领域里的大量工作 知之甚少，但是他在其他更家 内行 的实验者失败的问题上 取得了成功。
   succeed后要接状语从句，表示 在什么地方什么问题上 成功了。只有 where 才能构成状语从句。   5。The king commanded that enough money___to fund the project。
   collected st be collected collected n be collected \\\ A be collected command 后得that 从句中要使用虚拟语气 should+动词原形。
    should 可省略。 6。Frankly speaking,I'd rather you___anything about it for the time being。
   A。didn't do B。haven't done n't do D。have done \\\\\\\ A didn't do would rather + that 从句，要使用虚拟语气，that 从句中的动词 使用 过去式。
