While doing research for her new book, she came across a 16th-century French manuscript (手稿) consisting of nearly 1,000 sets of instructions, covering subjects from tool making to finding the best sand.
The author’s intention remains as mysterious (神秘) as his name; he may have been simply taking notes for his own records. But Smith was struck mainly by the fact that she didn’t truly grasp any of the skills the author described. “You simply can’t get an understanding of that handwork by reading about it,” she says.
Though Smith did get her hands on the best sand, doing things the old-fashioned way isn’t just about playing around with French mud. Reconstructing the work of the craftsmen (工匠) who lived centuries ago can reveal how they viewed the world, what objects filled their homes, and what went on in the workshops that produced them. It can even help solve present-day problems: In 2015, scientists discovered that a 10th-century English medicine for eve problems could kill a drug-resistant virus.
The work has also brought insights for museums, Smith says. One must know how an object was made in order to preserve it. What’s more, reconstructions might be the only way to know what treasures looked like before time wore them down. Scholars have seen this idea in practice with ancient Greek and Roman statues. These sculptures were painted a rainbow of striking colours. We can’t appreciate these kinds of details without seeing works of art as they originally appeared-something Smith believes you can do only when you have a road map.
Smith has put the manuscript’s ideas into practice. Her final goal is to link the worlds of art and science back together: She believes that bringing the old recipes to life can help develop a kind of learning that highlights experimentation, teamwork, and problem solving.
Back when science — then called “the new philosophy” — took shape, academics looked to craftsmen for help in understanding the natural world. Microscopes and telescopes were invented by way of artistic tinkering (修补), as craftsmen experimented with glass to better bend light.
“If we can rediscover the values of hands-on experience and craftwork,” Smith says, “we can marry the best of our modern insights with the handiness of our ancestors.”
According to Smith, the reconstruction work is done mainly to ________.| A．restore old workshops |
| B．understand the craftsmen |
| C．improve visual effects |
| D．inspire the philosophers |

6 . Frozen in time, a 125-million-year-old mammal attacking a dinosaur. A 39-million-year-old whale, the heaviest animal that ever lived. The oldest known jellyfish, from 505 million years ago. Paleontology (古生物学) produces newsworthy discoveries.
Fossils (化石), moreover, provide direct evidence for the long history of life, allowing paleontologists to test hypotheses (假设) about evolution with data only they provide. They allow investigation of present and past life on Earth. Flows of biological diversity, appearances of new life forms and the extinctions of long existing ones, would go undiscovered without these efforts. But the headlines over exciting new fossils greatly underestimate the true importance of paleontology. Its real significance lies in how such discoveries brighten the grand history of life on Earth. From its beginnings, more than three billion years ago, to the present day, fossils record how life adapted or disappeared in the face of major environmental challenges.
Paleontologists provide us with a unique vantage on modern climate change. They play an essential role in interpreting ancient environments, in reconstructing ancient oceans, continents and climates. Fossils provide key limitation on the climate models that are essential for predicting future climate change. And the fossil record gives important insights into how life will respond to predicted future climate conditions, because these have occurred before in Earth’s history.
In addition, paleontology has provided a fundamental contribution to human thought: the reality of species extinction and thus of a world that has dramatically changed over time. In documenting the history of life, paleontologists recognized that many extinction episodes could occur suddenly, such as the event 66 million years ago that ended the dinosaurs. The search for the causes of past mass extinctions started pioneering studies from across the scientific spectrum (科学界), focusing on potential future threats to humanity.
Not only do paleontologists know what happens to life when things go bad, they also know how long it takes for ecosystems and biodiversity to recover from these disasters, which can take far longer than modern humans have existed.
Paleontologists thus provide a unique perspective on the nature and future long-term ecological impact of the current human-produced biodiversity crisis, the so-called Sixth Extinction, and therefore the importance of protecting modern biodiversity. The very concept of a Sixth Extinction would not exist without paleontologists documenting the first five.
Paleontologists know that understanding life’s past is critical to anticipating and adapting to life’s and humanity’s future. Paleontology is important because it brings its unique and critical perspective to current challenges in climate change, biodiversity loss and the environment. Paleontologists can predict the future because they know the past.

9 . In the 17th century when a British businessman heard that there were one hundred million people in China, he was determined to go there and sell spoons. He thought even if he could earn one penny for one spoon, he would still make a lot of money.
Then, why do the Chinese people use chopsticks? Some people did research on the origin of China’s chopsticks. One theory is that chopsticks were very convenient for Chinese to use because China was an agricultural society, relying mainly on vegetables for food. When we steamed or boiled food, it was difficult for us to use spoons to dip vegetables in the soup.
Chopsticks reflect gentleness and kindness, the main moral teaching of Confucianism.
Today, chopsticks have become a typical part of Chinese culture, symbolising the power of unity.
| A．As a result, spoons were designed and preferred by Westerners. |
| B．But to his surprise, the Chinese people use chopsticks, not spoons. |
| C．Therefore, Chinese people cleverly invented chopsticks to pick food. |
| D．Besides, never point at people with your chopsticks while using them. |
| E．Indeed, one chopstick is useless and so delicate that it can be broken readily. |
| F．So these virtues have gradually become the rules people follow in their daily life. |
| G．There are some rules about using chopsticks that you should pay great attention to. |
