TPO1 Timberline Vegetation on Mountains - 英檢

※ 引述《comicduo (Jimmy)》之銘言：
: ※ 引述《alvinyeh (alvin)》之銘言：
: : Paragraph 1：The transition from forest to treeless tundra on a mountain
: : slope is often a dramatic one. Within a vertical distance of just a few tens
: : of meters, trees disappear as a life-form and are replaced by low shrubs,
: : herbs, and grasses. This rapid zone of transition is called the upper
: : timberline or tree line. In many semiarid areas there is also a lower
: : timberline where the forest passes into steppe or desert at its lower edge,
: : usually because of a lack of moisture.
: : 3. Which of the following can be inferred from paragraph 1 about both the
: : upper and lower timberlines?
: : 1 Both are treeless zones
: : 2 Both mark forest boundaries.
: 小弟分享一下小弟的看法
: 這題小弟倒是從來沒有考慮過 1
: 這題的題目問的是
: what can be inferred from paragraph 1
: about both the upper and lower timberlines?
: 那小弟先請問一下原PO
: timberline "本身是" treeless 還是 把treeless 和 trees zone 分開的一個邊界
: 文章可從頭到尾都只有告訴過讀者說 "那條line上面植物分布的狀況"
: 可從來沒有有告訴過讀者說 那條line上面是treeless的
: 就算是infer 也只能infer出那條line上面的樹越來越少
: 所以 1 就不成立了
: 3 4 不列入思考 所以答案刪去1 3 4後 就是2啦
: 純粹只是小弟淺見 還請大家討論指教
