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?
正确答案：D
解析：短文提到，“我”画树时会用很多浓淡不同的绿色和更多不同色调的褐色。可知“我”用了多种颜色。所以D正确。由选项中的关键词可猜测本题问与画画有关的内容。原文提到“我”用了不同色度的绿色和棕色来画树，其中棕色比绿色要多，因此排除A。shade“色调”与shadow“阴影”发音相似，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"?
正确答案：B
解析：短文提到，树木的气味有如夏日里的一杯凉水，滚烫的额头前一块湿润的布，令人感觉清新。故答案为B。四个选项分别是对树木的外观和质感的描述，可猜测话题与树木的特征有关。文中相关的地方重复了两次smell这个词，而且用refreshing来补充说明它的效果。
34. What does the speaker like doing in the grandfather's tree?
正确答案：D
解析：短文提到，“我”小时候喜欢爬上爷爷的苹果树，边思考边吃苹果。故答案为D。四个选项都是动名词结构，描述某人的活动细节，其中A、B两项与树有关。另外选项内的eating，是原词再现，听到什么选什么。
35. According to the speaker, how do trees make life possible?
正确答案：C
解析：短文提到，树木为生命提供可能，是因为它们吸收二氧化碳和释放出氧气，使我们能呼吸。故答案为C。根据选项的描述，联系上几道题的选项，可知这道题的主题是“树”，因此，主语they指的是trees。每项的描述本身都没有错，估计问题规定了某些范围或条件，解题的关键是有针对性地回答问题。
