Passage Three
I love trees because they have many different shades of green, so many that it's almost impossible to count. When I paint a picture of a tree I [32]use many shades of green and many more shades of brown. My favorite thing about trees is that they always seem to have a glow around them. I love trees because they always smell so fresh and clean. I like to go to the nursery because I [33]love the smell of trees, it's so refreshing. It's a glass of cool water on a hot day, or a damp cloth on a hot forehead.
One of my favorite things about trees is that they are fun to climb. I started climbing trees when I was very little. I especially like to climb my grandpa's apple tree. I love to wind through the branches, and climb up to a board that has been placed there. [34]Once up, I like to think and relax, or bring a book up there with me. It's fun to let my imagination run away with me while eating apples.
I love trees in the autumn when they display their beautiful colors. In the autumn time, splashes of red, yellow, orange, and green decorate the mountainsides. The maples go red, the oak and aspen go yellow while the evergreens maintain their beautiful shade of green.
[35]Trees make life possible because they use the carbon dioxide and release oxygen which makes it so that we can breathe. If we exterminate trees, the effects could be fatal. There may be global warming, lack of oxygen, and we would definitely not have any lumber or paper.

Questions 32 to 35 are based on the passage you have just heard.
32. What does the speaker do when painting pictures of trees?
正確答案：D
解析：短文提到，“我”畫樹時會用很多濃淡不同的綠色和更多不同色調的褐色。可知“我”用了多種顏色。所以D正確。由選項中的關鍵詞可猜測本題問與畫畫有關的內容。原文提到“我”用了不同色度的綠色和棕色來畫樹，其中棕色比綠色要多，因此排除A。shade“色調”與shadow“陰影”發音相似，是B迷惑性所在。
33. What aspect of trees is the speaker referring to when saying that "It's a glass of cool water on a hot day"?
正確答案：B
解析：短文提到，樹木的氣味有如夏日里的一杯涼水，滾燙的額頭前一塊濕潤的布，令人感覺清新。故答案為B。四個選項分別是對樹木的外觀和質感的描述，可猜測話題與樹木的特征有關。文中相關的地方重復了兩次smell這個詞，而且用refreshing來補充說明它的效果。
34. What does the speaker like doing in the grandfather's tree?
正確答案：D
解析：短文提到，“我”小時候喜歡爬上爺爺的蘋果樹，邊思考邊吃蘋果。故答案為D。四個選項都是動名詞結構，描述某人的活動細節，其中A、B兩項與樹有關。另外選項內的eating，是原詞再現，聽到什么選什么。
35. According to the speaker, how do trees make life possible?
正確答案：C
解析：短文提到，樹木為生命提供可能，是因為它們吸收二氧化碳和釋放出氧氣，使我們能呼吸。故答案為C。根據選項的描述，聯系上幾道題的選項，可知這道題的主題是“樹”，因此，主語they指的是trees。每項的描述本身都沒有錯，估計問題規定了某些范圍或條件，解題的關鍵是有針對性地回答問題。
