※ 引述《kuoyuhsuan (yuhsuan)》之銘言：
: PARAGRAPH 2:
: Nearly any kind of plant of the forest understory can be part of a deer's diet.
: Where the forest inhibits the growth of grass and other meadow plants,the
: black-tailed deer browses on huckleberry,salad, dogwood, and almost any
: other shrub or herb. But this is fair-weather feeding.What keeps the black-
: tailed deer alive in the harsher seasons of plant decay and dormancy?
: One compensation for not hibernating is the built-in urge to migrate. Deer
: may move from high-elevation browse areas in summer down to the lowland areas
: in late fall.Even with snow on the ground, the high bushy understory is
: exposed; also snow and wind bring down leafy branches of cedar,hemlock,red
: alder, and other arboreal fodder.
: 2.It can be inferred from the discussion in paragraph 2 that winter conditions
: 1.cause some deer to hibernate
: 2.Make food unavailable in the highlands for deer
: 3.make it easier for deer to locate understory plants
: 4.prevent deer from migrating during the winter
: 答案是3但我選4!????
: 想請教大家這一題
: 還有文章裡的understory是甚麼意思?!
: 謝謝!
"Even with snow on the ground, the high bushy understory is exposed; also
snow wind bring down leaf branches……
意思是："即使地上有積雪，灌木下層較高處依然暴露在外；雪和風也會將長樹葉的樹枝
往下帶…。"言下之意，在冬天，deer還是可以取得食物。
understory指的是森林中較下層接近地面的部份。
