A
Mama and I spend mornings cleaning up the dirt that blows into our house. Mama says all the dust is due to the drought. The dirt sifts into everything. It covers our clothes. We have to wash the dishes before each meal. We rarely drive the truck because Papa fears the dust from the road will ruin the motor.
When my sister, Faye, and I walk to school, we wear kerchiefs over our mouths so we don’t breathe in the dirt. On days when the air is so bad that they close the school, we stay home and help Mama put wet sheets over the windows. But the dirt always finds a way in.
Last Sunday, there was no dirt in the air, only bright spring sunshine and a clear blue sky. After lunch, Papa headed out to the field to check on the cattle while I played with Faye in the yard. The temperature suddenly dropped. I looked to the west and saw a huge black cloud of dust. All the birds flew away. “I must warn Papa,” I thought to myself. To avoid her panicking, I gently told Faye to go back inside where she would be safe, and then headed off to the field.

The storm hit so fast, and in an instant the day turned into night. By the time I entered the cow field the fine sand was whipping across my face. I screamed for Papa, hoping my voice would lead him back.
The dirt and sand stung my skin like a thousand bees. Although I was terrified, I refused to turn back. My dad was stranded and needed my help. Covering my face with one hand, I groped my way toward the truck and opened the door. First I tried turning the truck’s lights on and off, hoping that Papa would see them flashing, but the sandstorm let no light escape. Then I pushed the horn again and again, so Papa would hear it. I pushed until I had no more strength in my arms.
Suddenly, Papa’s face appeared at the window. My heart leaped with surprise and relief. He opened the door and climbed onto the seat next to me. He then pulled me into his arms and said, “Oh, Iris, you saved me!”
Finally, the wind subsided and the dust began to settle. Dirt was piled up to the window on one side of the truck and halfway up the door on the other. Papa kicked against the door, opening it far enough to let us out.
Sand and soil drifts were everywhere, but we were safe.

The Silk Road is arguably the most famous long-distance trade route of the ancient world. This passage connected Europe in the West with China in the East, and allowed the exchange of goods, technology, and ideas between the two civilizations. Although merchants could make huge profits travelling the road, it was not without risk.
The main Silk Road started in Chang’an (known today as Xi’an), the early Han capital. Travelers commencing their journey from this city could take a northern route that would take them across China’s northwestern provinces. After this, they would face the Gobi Desert, arguably the greatest danger of the Silk Road.
The Gobi Desert, the largest desert in Asia, consists mainly of rocky, hard earth. This feature made it easier for traders to travel across, compared to sandy deserts like the neighboring Taklamakan Desert. Like other deserts, the Gobi Desert is dry and hot, and therefore the biggest challenge travelers faced was obtaining enough water for themselves as well as for their camels.
So, rest stops were created along the route, allowing travelers to rest, eat and drink. These places also promoted the exchange of goods, and even ideas, amongst the travelers who stopped there. Usually, the rest stops were placed within a day’s journey of each other. In this way, travelers could avoid spending too much time in the desert, which would make them targets for robbers, another danger of the Silk Road.
Once through the Gobi Desert, travelers would continue their journey into Iran, Turkey, and finally Europe. Whilst this part of the journey may have been less dangerous, it is not entirely without its perils.
28. The underlined word “it” in the first paragraph refers to A. making huge profits B. traveling the Silk Road C. exchanging goods and ideas D. connecting different civilizations
29. Why was the Gobi Desert easier to cross than other deserts? A. The desert’s surface was easier to walk on. B. Camels for transportation were easier to find. C. It was smaller and could be crossed in less time. D. There were more natural water sources available.

30. What can we guess about the rest stops in the Gobi Desert? A. Travelers were offered free accommodation. B. They were located around the edges of the desert. C. Travelers staying there were often attacked by criminals. D. They were shared by travelers from different countries. 31. What is the passage mainly about? A. The origins of the Silk Road. B. The benefits of the Silk Road.
C. The difficulties faced by Silk Road travelers. D. The cultural exchanges among Silk Road travelers.
D
Let’s begin with the story: King Hiero contracts the ancient Greek polymath Archimedes ( 阿基米德) to detect fraud in the manufacture of a golden crown. Archimedes accepts the challenge
and, during a subsequent trip to the public baths, realizes that the more his body sinks into the water, the more water is displaced — making the displaced water an exact measure of his volume. Realizing he has hit upon a method to determine whether the King’s crown was made of gold or silver, the young Greek leaps out of the bath and rushes home naked crying “Eureka! Eureka!” Or, translated: “I’ve found it! I’ve found it!”
Too bad, however, Archimedes probably never uttered the phrase in that way.
First and foremost, Archimedes himself never wrote about this episode, although he spent plenty of time detailing the laws of buoyancy ( 浮 力 ). The oldest authority for the naked-Archimedes eureka story is Vitruvius, a Roman writer, who included the tale in his introduction to his ninth book of architecture. “Vitruvius may have gotten it wrong,” says Chris Schmitt, a mathematician at the University of Berlin and a self-described Archimedes fan. “The method attributed to Archimedes in the story works in theory so it sounds right, but when you actually try it, you find that the real world gets in the way.”
In fact, Schmitt is one of a long line of scientists, including Galileo, who have read the account and thought, “That can’t be right.” As Galileo wrote, Archimedes could have achieved a far more precise result using his own law of buoyancy and an accurate scale. In fact, the surface tension of water can make the volume of a light object like a crown immeasurable. “There may be some truth to it,” Schmitt adds. “Archimedes did measure the volume of things but the eureka moment was maybe due to his original discovery concerning buoyance, not to sitting in the bathtub and then running through the streets naked.”
