第 28 格應填入： (A) In arctic and Antarctic regions, there is very little rain. (B) Hot deserts, on the other hand, have high temperatures, usually over 75°F. in the daytime. (C) Because it stays frozen on the ground, plants cannot use it to grow. (D) In many hot deserts, the wind has blown away the sand, leaving bare rock, boulders, and gravel.

正確答案為 B。本題為填空題，需找出接續「冬夏低溫範圍」後、引入「熱沙漠」話題的銜接句，答案為B（介紹熱沙漠高溫特徵）。 (A) 【語篇銜接／段落轉換】A句「北極與南極地區降雨很少」屬於冷沙漠的補充，與空格27的「Because it stays frozen on the ground, plants cannot use it to grow」更搭配（說明降水結凍植物無法利用），放在28反而破壞段落從冷沙漠轉向熱沙漠的邏輯。 (B) 【語篇銜接／主題句識別】空格28緊接在第一段末（冷沙漠溫度介紹完畢）與第二段首（「As with cold deserts, there is usually little water available for plant growth」開始討論熱沙漠），B句「熱沙漠日間溫度通常超過75°F」正好完成冷→熱的段落轉換，是開啟第二段的主題句。

What do you think of when you hear the word "desert"? We usually think of deserts as hot, dry places. In fact, there are both hot and cold deserts in the world. Scientists defined deserts as areas of land where there are less than ten inches of rainfalls per year and there are few plants. ＿＿（26）＿＿ Precipitation is almost always frozen in the form of ice or snow. ＿＿（27）＿＿ So these regions are considered deserts and given the special label "cold deserts." The low temperature there ranges from 10 to 50°F. in summer and from -50 to 10°F. in winter. ＿＿（28）＿＿ As with cold deserts, there is usually little water available for plant growth. But contrary to what many people think, hot deserts are not lifeless wastelands. ＿＿（29）＿＿ These species have learned to adapt to the lack of water and harsh temperatures. Also, they are not necessarily made up of endless shifting sand dunes. ＿＿（30）＿＿ Some deserts have steep, rocky mountains, while others are flat.
