※ 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
