(2) cliff swallows develop shorter wings
(3) crows drop nuts near a driving school
(4) anole lizards grow longer legs and stickier feet

解答（逐步）
行為改變：(1) foxes 夜獵、(3) crows 借車輾果（學來的習慣）。
演化改變：(2) cliff swallows 短翅、(4) anole 長腿黏腳、(5) white-footed mice 突變（基因層次、跨世代）。
進階辨識 counterargument → acknowledgement → refutation☐完成
讀下段，標出反論 (C)、讓步 (A)、反駁 (R) 各一句：
"Opponents of vertical farming maintain that it is far too expensive to build and run. Although it is true that the start-up cost is high, the price of LED lights is rapidly falling, so these farms will soon become affordable."
提示
反論常以 Opponents maintain… 起；讓步常以 Although it is true… 起；反駁常用對比/結果連接詞銜接。
解答（逐步）
C（counterargument）：Opponents of vertical farming maintain that it is far too expensive to build and run.
A（acknowledgement）：Although it is true that the start-up cost is high,
R（refutation）：the price of LED lights is rapidly falling, so these farms will soon become affordable.
進階因果連接詞詞性判斷與填空☐完成
從 because of / as a result / due to / consequently / thanks to 選填，並說明後面接名詞片語還是子句：
(1) ___ the falling cost of LED lights, vertical farming is becoming more practical.
(2) Many swallows with long wings could not avoid cars. ___, only short-winged birds survived.
(3) Its use is not yet widespread ___ the high cost.
提示
介系詞 (because of / due to / thanks to) 後接名詞片語；轉折詞 (as a result / consequently) 後接獨立子句。
解答（逐步）
(1) Because of / Thanks to（介系詞）＋名詞片語 the falling cost…。
(2) As a result / Consequently（轉折詞）＋獨立子句 only short-winged birds survived。
(3) due to（介系詞）＋名詞片語 the high cost。
挑戰用指定連接詞改寫因果句（課本 G 題型）☐完成
用括號裡的連接詞改寫，注意詞性：
(1) Many people have left farms because there are new job opportunities in cities. (because of)
(2) Many animals have left their wild homes because there is generally more food in cities. (consequently)
(3) These mutations are helpful, so the animals can survive more easily. (thanks to)
(4) The cost of this technology is quite high, so its use is not yet widespread. (due to)
提示
because of / thanks to / due to 後接名詞片語，需把子句改名詞化；consequently 後接獨立子句。
解答（逐步）
(1) Because of new job opportunities in cities, many people have left farms.
(2) There is generally more food in cities. Consequently, many animals have left their wild homes.
(3) Thanks to these helpful mutations, the animals can survive more easily.
(4) Due to the high cost of this technology, its use is not yet widespread.
挑戰T/F/NG 判斷（Feeding the City）☐完成
依 Reading 2「Feeding the City」判斷 True / False / Not Given 並說明：
(1) Pesticides used on traditional farms can poison nearby water.
(2) Vertical farms use solar energy, so they have a smaller carbon footprint.
(3) Vertical farms use much less water than traditional farms.
(4) Vertical farms use apps to deliver food to their customers.
提示
False＝文章有相反；Not Given＝完全沒提；NG≠False。
