【答案解析】Prompt
Using points from the lecture, explain how the passion plant and the potato plant defend themselves from insects.
Important Points
For this task, you should use the examples from the lecture to explain how plants defend themselves from insects. You should explain that plants can use both physical and chemical defenses. The passion plant uses a physical defense. This plant has spiky hairs on its leaves which prevent insects from landing on the plant and eating the leaves. The potato plant, on the other hand uses a chemical defense. This plant releases a chemical through its leaves when an insect eats it. The chemical makes the insect feel full, so it stops eating the plant.

The speaker gives a well-organized, clear response and is able to summarize all of the important information from the lecture. He jumps immediately into a summary of the examples, but he shows a clear connection between the two examples to the main concept. Consider his sentence: " On the other side, potato plants uses chemical features to prevent being eaten by insects ." Though there are some grammatical errors in this sentence, he uses a transitional phrase " on the other side ," and he stresses the word " chemical " to emphasize the contrast between the two examples. He does speak very quickly at times, but he shows that he is able to communicate without too many pauses and searching for words. He makes occasional pronunciation errors but has the ability to correct himself. For instance, he describes the chemical defenses that the potato plant uses " to prevent being eaten ." At first, "being eaten" is pronounced incorrectly, but he quickly corrects his pronunciation and continues with the response.

This speaker is able to convey all of the important points from the lecture, but her response takes some effort to understand. She pauses frequently, searching for words. She clearly understood and is able to explain both examples, but her vocabulary is sometimes vague (" the potato plant has some, like, chemical things ") or inaccurate. For instance, in the first point about the passion plant, she describes the spikes " which prevent him from the insect " instead of "which protect it from the insect." Her pronunciation is mostly easy to understand, but she does make a few mistakes that confuse her meaning. For example, while describing the chemical defenses of the potato plant, she says that " the insect doesn"t feel hungry ," but her pronunciation of "hungry" sounds more like "angry." [听力原文]
