TPO 11 MINERALS AND PLANTS - 英檢

根據題目所述，我們很快的在閱讀 passage 裡找 "standard practices for
remediation of contaminated suils"。我們在 passage 約 2/3 處找到 "after
several years of cultivation and harvest, the site would be restored at a
cost much lower than the price of excavation and reburial, the standard
practice for remediation of contamindated soils"。這一句提到時間 "After
several years"，所以我們得知時間是一個關鍵因素，而且需要的不是短時間；我們找答
案 "is less suitable for soils that need to be used within a short period of
time"不適合短時間內就要用的土壤，是正確答案。

很多同學都希望能夠不用翻譯全句而找到答案，這邊所示範的就是根據關鍵字句快速找到
答案的方法，但是前提是同學基礎功夫要有，閱讀速度要快才能迅速找到關鍵句，字彙量
要夠才能讀得快也讀得懂。基本功夫有底子，我們就可以進階用技巧來找正確答案了。

※ 引述《tom192180 (tom510558)》之銘言：
: Paragraph 6:
: Only recently have investigators considered using these plants
: to clean up soil and waste sites that have been contaminated by toxic levels
: of heavy metals – an environmentally friendly approach known as
: phytoremediation. This scenario begins with the planting of hyper
: accumulating species in the target area, such as an abandoned mine or an
: irrigation pond contaminated by runoff. Toxic minerals would first be
: absorbed by roots but later relocated to the stem and leaves. A harvest of
: the shoots would remove the toxic compounds off site to be burned or
: composted to recover the metal for industrial uses. After several years of
: cultivation and harvest, the site would be restored at a cost much lower than
: the price of excavation and reburial, the standard practice for remediation
: of contaminated soils. For examples, in field trials, the plant alpine
: pennycress removed zinc and cadmium from soils near a zinc smelter, and
: Indian mustard, native to Pakistan and India, has been effective in reducing
: levels of selenium salts by 50 percent in contaminated soils.
: 11. It can be inferred from Paragraph6 that compared with standard practices
: for remediation of contaminated soils, phytoremediation
: 1.does not allow for the use of the removed minerals for industrial purposes.
: 2.can be faster to implement
: 3.is equally friendly to the environment
: 4.is less suitable for soils that need to be used within a short period of
: time.
: 答案是四， 想請問大家為什麼是四= =
: 他不是說"compare with standard practices for remediation" 可是文章沒有說
: standard practices for remefiation 比較適合說@@
: 請大家解答摟 !!!謝謝~
