Aloe vera is succulent plant from whose leaves are extracted a gel that has been prized since ancient times for is medicinal properties
a.plant from whose leaves are extracted
b.plant from whose leaves is extracted
c.plant form whose leaves they extract
为你解答如下:
第1题,c正确
“国旗被升起来”,用及物动词raise,因为及物动词才有被动形式.
第2题,b正确
主题不同的情况下,主语必须分别出现在主句和从句中,才不会引起意思混乱.
第3题,b正确
从句中含有倒装,主语实际上是a gel,那么谓语动词得用“三单式”is extracted,即a gel is extracted from whose leaves 才符合语法规范.
再问: 第一题其他两个哪里错了
再答: 第1题, is risen 错了,因为rise 是不及物的,没有被动语态。 is rising 是现在进行时,表示“现在正在升起”,和时间状语 each morning 无法搭配使用。
