Re: [語文] PP-T1-CR-24
這題大概是說，虎甲蟲可以抓到任何沒有在飛的動物
但當虎甲蟲朝昆蟲(獵物)衝去，它不時會停頓一下，然後再繼續它的攻擊
對於這樣的間隔的停頓有兩種假設
1.有人認為虎甲蟲無法持續不停止的進行它的攻擊路線，需要行進間須停頓休息
2.虎甲蟲行進間無法及時的接收處理視覺，暫時會處於看不見的狀態，所以才會有停頓
a.已經離題，他說當虎甲蟲的獵物轉而朝虎甲蟲跑來，虎甲蟲會一反常態的不做停頓跑走
(個人覺得這選項超像笑話的 XD)
bc可以一起做討論
b.他說在虎甲蟲進行攻擊的時候，會及時反應獵物上下左右移動、改變方向，
並且過程中虎甲蟲所作的停頓是規律的。
c.這個選像是說，儘管面前獵物從靜止到開始移動，虎甲蟲仍按照自己規律的步調停頓
但是它會為了去捕捉獵物而加速移動
因此C比B更加支持了假設1，虎甲蟲有它自己的停頓步調而作休息，而不是隨獵物而改變
另外虎甲蟲也會在停頓後加速去追捕獵物，證明剛剛在他眼前的獵物開始移動這件事情，
虎甲蟲是有看到的，因此假設二它無法及時處理眼前快速接收到的視覺這個理論就被
削弱了

: Tiger beetles are such fast runners that they can capture virtually any
: nonflying insect. However, when running toward an insect, the beetles
: intermittently stop, and then, a moment later, resume their attack.
: Perhaps they cannot maintain their pace and must pause for a moment's rest;
: but an alternative hypothesis is that while running tiger beetles are unable
: to process the resulting rapidly changing visual information, and so quickly
: go blind and stop.
: Which of the following, if discovered in experiments using artificially
: moved prey insects, would support one of the two hypotheses and undermine
: the other?
: (A) When a prey insect is moved directly toward a beetle that has been chasing
: it, the beetle immediately turns and runs away without its usual
: intermittent stopping.
: (B) In pursuing a moving insect, the beetles usually respond immediately
: to changes in the insect's direction, and pause equally frequently
: whether the chase is up or down an incline.
: (C) The beetles maintain a fixed time interval between pauses, although when
: an insect that had been stationary begins to flee, the beetle increases
: its speed after its next pause.
: (D) If, when a beetle pauses, it has not gained on the insect it is pursuing,
: the beetle generally ends its pursuit.
: (E) When an obstacle is suddenly introduced just in front of running beetles,
: the beetles sometimes stop immediately, but they never respond by running
: around the barrier.

: 這一題真的很瘋狂，不懂C如何支持其中一個假設，削弱另一個.....
: 有沒有人知道呢？
