Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna surroundings in which it lives, therefore _ of existence for millions of other animals that live in its habitat. It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas . In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters. Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well. What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem. Question: The passage is developed mainly by _ . Options: A: showing the effect and then explaining the causes B: pointing out similarities and differences C: describing the changes in space order D: giving examples

Q: Read the article and select the best answer. Article: What are you feeling right now as you start to read this? Are you curious? Hoping that you'll learn something about yourself?

Perhaps you're attracted by something else, like feeling excited about your weekend plans or sad because you just went through a breakup. Emotions like these are part of human nature. They give us information about what we're experiencing and help us know how to react. We sense our emotions from the time we're babies. Young children react to their emotions with facial expressions or with actions like laughing or crying. They feel and show emotions, but they don't yet have the ability to name the emotion or say why they feel that way. As we grow up, we become more skilled in understanding emotions. Instead of just reacting like little kids do, we can identify what we feel and put it into words. With time and practice, we get better at knowing what we are feeling and why. This skill is called emotional awareness. Emotional awareness helps us know what we need and want, or don't want! It helps us build better relationships. That's because being aware of our emotions can help us talk about feelings more clearly, avoid or settle conflicts better, and move past difficult feelings more easily. Some people are naturally more in touch with their emotions than others. The good news is that everyone can be more aware of their emotions. It just takes practice. But it's worth the effort. Emotional awareness is the first step toward building emotional intelligence, a skill that can help people succeed in life. Question: How do young children react to emotions? Options: A: With laughter and shouts. B: With signs and expressions. C: With facial expressions and actions. D: With gestures of different kinds.
