文章大意:这是一篇说明文。文章讲述了,研究人员通过研究西班牙加那利群岛的沉积物,发现了撒哈拉尘埃的证据,通过评估古代土层中灰尘的年龄来确定撒哈拉沙漠的形成时间,报告说撒哈拉沙漠有近500万年的历史。

1 . The Sahara is the world’s largest and most magic desert, but knowledge about it is surprisingly limited. Even estimates of when it formed vary widely, from more than five million years ago to mere thousands. Now, however, geographers studying wind-carried Saharan dust on the Canary Islands have come closer to settling this: it is, they report, close to five million years old.

One reason for the uncertainty over the Sahara’s age is that researchers use different methods to estimate it. These include studying desert dust found in sediment (沉积物) under the Atlantic Ocean, analyzing sandstone and modeling the ancient climate. To help settle the uncertainty, Daniel, geographer of the U.S. Geological Survey, and his workmates looked at sediment on Spain’s Canary Islands. They found evidence of Saharan dust. The dust appeared in ancient soil layers (层), whose age they assessed on the basis of fossils (化石) found in the same layers — and that age agreed with the earlier ocean’s sediment studies. The researchers reported their findings in November in Palaeogeography.

“The conclusion of the study is very good,” says Zhongshi Zhang, a climate modeler at the University of Bergen in Norway, who was not involved in the work. “Because the dust found on the islands is distinct from the ocean’s record,” Zhang adds, “it helps to build the case for a five-million-year age.”

The Sahara is the biggest source of wind-carried dust in the world — and that dust’s journey does not end in the Canary Islands, which lie just off the western coast of Africa. It continues onto places such as the Amazon rain forest in South America, Daniel notes. Amazon soils are poor in nutrients, and he says the new results help to show how rich dust from Africa could have been supporting the South American region’s incredible biodiversity for millions of years — adding to the Amazon’s own origin story.

1. How did Daniel settle the formation time of the Sahara?
A.By modeling the ancient climate in Spain’s islands.
B.By studying the desert dust under the Atlantic Ocean.
C.By assessing the age of the dust in ancient soil layers.
D.By analyzing the wind-carried sandstone in the Sahara.
2. What is the underlined words “their findings” in the paragraph 2 refer to?
A.The appearance of the dust.B.The formation of two layers.
C.The age of the Saharan dust.D.The agreement of two layers.
3. What contributes to the biodiversity of the South America?
A.The Saharan dust.B.The Amazon soils.
C.The Amazon rain forest.D.The Coastal waters.
4. Which is the most suitable title for the text?
A.The Study of the Sahara.B.The Birth of the Sahara.
C.The Source of the Sahara.D.The Effect of the Sahara.

2 . Standing on the shore of a lake, I can’t help but feel surprised at the thousands of small rocks that surround my boots. They were all created from _________ surfaces, their edges softening over time. I wonder, “Can we learn from a pile of rocks?”

Even the tallest mountains have _________; none are as tall as they were 1,000 years ago. And much like a rock, I’ve found my _________ has softened and my desire to better understand others has expanded with each trip around the sun.

_________, I was also a sharp rock covered in pointy edges. Today, after decades of the waters of life coursing over me, my edges are softer and I’m more _________. I’m less likely to judge and more interested in learning how we can _________ together.

Two years ago, while traveling in the Pacific Northwest, I watched a restaurant owner ask several young men to _________ for not wearing masks. Not _________ and not rude.

The group of young men wanted to __________ about the note. I sat at the restaurant watching, understanding both sides. I’ve been one of them before, using my youthful edges to chip away at (削弱) the world. What I lost, __________, was the ability to grow from __________ by looking through the eyes of others. In learning to be more __________, I’ve also found more happiness and success.

You can fit more rounded rocks in a jar than those with sharp edges. The former look for ways to __________ and make room for others, while the latter never give an __________ to accommodate others.
