[請益] TPO9 THE ARRIVAL OF PLANT LIFE IN HAWAII
Paragraph 3: Lichens helped to speed the decomposition of the hard rock
surfaces, preparing a soft bed of soil that was abundantly supplied with
minerals that had been carried in the molten rock from the bowels of Earth.
Now, other forms of life could take hold: ferns and mosses (two of the most
ancient types of land plants) that flourish even in rock crevices. These plants
propagate by producing spores-tiny fertilized cells that contain all the
instructions for making a new plant-but the spores are unprotected by any outer
coating and carry no supply of nutrient. Vast numbers of them fall on the
ground beneath the mother plants. Sometimes they are carried farther afield by
water or by wind. But only those few spores that settle down in very favorable
locations can start new life; the vast majority fall on barren ground. By force
of sheer numbers, however, the mosses and ferns reached Hawaii, survived, and
multiplied. Some species developed great size, becoming tree ferns that even
now grow in the Hawaiian forests.
6. According to paragraph 3, what was the relationship between lichens and
ferns in the development of plant life on Hawaii?
○Ferns were able to grow because lichens created suitable soil.
○The decomposition of ferns produced minerals that were used by lichens.
○Lichens and ferns competed to grow in the same rocky environments.
○Lichens and ferns were typically found together in volcanic areas.
我考慮AD 最後選A
但原因不是很確定
因為文章一開始提到lichen會讓土壤更有營養
但沒有明確指出對fern及moss的好處
文中提到lichen被發現在molten rock
又說fern及moss之後接手(take hold)
所以有考慮答案D
正確解答給D
因為我下載兩個板本的黃金閱讀
另一個版本竟然給A
請問大家這題正確答案是甚麼呢?
謝謝大家的解答!
