語法的幾個問題 麻煩看下
1.Experiments show that insects can function as pollinators of cycads,rare,palmlike tropical plants.這句話rare,palmlike tropical plants是插入語還是同位語還是?為什么?
2.Because the potential hazards pollen grains are subject to as they are transported over long distances are enormous,wind pollinated plants have compensated for the ensuing loss of pollen.從句中有because和as 2個連詞,一個狀語從句里面還可以再加一個狀語從句?
3.The change met the technical requirements of the new age by engaging a large professional element and prevented the decline in efficency that so commonly spoiled the fortunes of family firms in the second and third generation after the energetic founders.后半部分that引導(dǎo)的是什么從句?怎么看的?
