Storytelling is one of the few human features that are truly universal across culture and through all of known history. Anthropologists find evidence of folktales everywhere in ancient cultures,written in Sanskrit，Latin，Greek，Chinese，Egyptian and Sumerian. People in societies of all types weave stories，from oral storytellers in hunter-gatherer tribes to the millions of writers bringing out books，television shows and movies. And when a characteristic behavior. shows up in so many different societies. researchers pay attention：its roots may tell us something about our evolutionary past.

To study storytelling，scientists must first define what constitutes a story，and that can prove tricky. Because there are so many diverse forms，scholars often define story structure. known as narrative，by explaining what it is not. Exposition contrasts with narrative by being a simple，straightforward explanation，such as a list of facts or an encyclopedia entry. Another standard approach defines narrative as a series of causally linked events that unfold over time. A third definition draws on the typical narrative's subject matter：the interactions of intentional agents-characters with minds-who possess various motivations,

However narrative is defined，people know it when they feel it. Whether fiction or nonfiction. a narrative engages its audience through psychological realism-recognizable emotions and believable interactions among characters.

“Everyone has a natural detector for psychological realism，”says Raymond A. Mar，assistant professor of psychology at York University in Toronto. “We can tell when something rings false. ”But the best stories-those retold through generations and translated into other languages-do more than simply present a believable picture. These tales attract their audience. whose emotions can be closely tied to those of the story's characters. Such immersion(沉浸)is a state psychologists call“narrative transport”. Researchers have only begun figuring out the relations among the variables that can initiate narrative transport.

The passage indicates that storytelling______.

A．is becoming less and less popular in modem societies

B．attracts researchers' attention all through human history

C．is the best way to show the evolutionary past of human beings

D．is a common cultural phenomenon all through the known history

Soil quality is one of the most basic and perhaps least understood indicators of land health. Soil supports plant growth and represents the living reservoir that buffers tile flows of water, nutrients, and energy through an ecosystem. Soil quality refers to the capacity of a soil to perform. these beneficial functions and is determined by its texture, structure, water-holding capacity, porosity, organic matter content, and depth, among other properties. Because soils naturally vary in their capacity to perform. these functions, we must tie our understanding of soil quality to landscapes and land use. We must understand soil quality for two important reasons: First, we must match our use and management of land to soil capability. Second, we must establish baseline understanding about soil quality so we can recognize ongoing trends. If soil quality is stable or improving, we have a good indicator that the ecosystem is sustainable. If soil quality is deteriorating, the larger ecosystem will almost certainly decline with it.

People describe soil types in all kinds of ways such as heavy, light, sandy, clay, loam, poor or good. Soil scientists describe soil types by how much sand, silt and clay is present. This is called texture. It is possible to change the texture by adding different things to the soil. You can roughly estimate the texture of a soil by a simply method called "manual texturing", through determining the feel of a moist sample when rubbed between the thumb and forefinger. If the soil sample is predominantly sand, it will feel very gritty. If it is predominantly silt, it will feel smooth or slippery to the touch. And if it is predominantly clay, it will feel sticky.

Particle size has a lot to do with a soil's drainage and nutrient holding capacity. Sand is the largest particle and doesn't hold many nutrients. Silt is a soil particle whose size is between sand and clay. When wet, silt feels smooth but not sticky. Clay is smooth when dry and sticky when wet. Soils high in clay content are called heavy soils. Clay also can hold a lot of nutrients, but doesn't let air and water through it well. To better understand how big these three soil particles are, think of them like this. If a particle of sand were the size of a basketball, then silt would be the size of a baseball, and clay would be the size of a golf ball.

What does the passage mainly discuss?

A．Characteristics of soil quality.

B．Particles typically found in soils.

C．The importance of soil texture.

D．How to determine soil texture.
