五、任务型阅读
阅读下面短文，简略回答问题。
Plants: more than we thought
Plants are amazing! In the past, there were some ideas that plants had feelings and could act like people. But now, new studies show that plants are unusual in their own ways.
Protecting (保护) themselves
One way is how plants protect themselves. For example, when worms eat them, tomato plants can make their leaves taste bad with a special juice. This can even make the worms eat each other! Corn (玉米) plants can check what worms leave behind and then use that information to call a bee to hunt the worms.
Plant communication
Plants can also talk to each other. They mainly use special air. There are small openings on plants that look like little fish mouths under a microscope. These openings let out air with information. When a plant has problems, like being eaten or hurt by wind, it sends a “call”. Other plants close to it can get this “call” and get ready to stay safe.
Plant memory
Do plants have memory One example is the “memory of winter”. Many fruit trees need to “remember” the number of cold days in winter to blossom in spring. They remember the cold and warm days to stop flowering too early during a warm time in winter.
Now, when we look at plants in a park, we can think of them as little “strangers” (陌生人) with their own “stories” going on all around. We don’t know if they feel pain (疼痛), but they sense touch or respond to being eaten, even though they don’t feel pain like we do.
28．What can tomato plants do when worms eat them
29．What do plants mainly use to talk to each other
30．Why do plants remember the cold and warm days in winter
31．What’s the main idea of the passage
32．How do you usually look after the amazing plants around us
