3 . Each year, the world loses about 10 million hectares of forest—at area about the size of Iceland — because of cutting down trees. At that rate, some scientists predict the world’s forests could disappear in 100 to 200 years. To handle it, now researchers at Massachusetts Institute of Technology (MIT) have pioneered a technique to generate wood-like plant materials sin a lab. This makes it possible to “grow” a wooden product without cutting down trees.
In the lab, the researchers first take cells from the leaves of a young plant. These cells are cultured in liquid medium for two days, then moved to another medium which contains nutrients and two different hormones (激素). By adjusting the bormone levels, the researchers can tune the physical and mechanical qualities of the cells: New the researchers use a 3D printer to shape the cell-based material, and let the shaped material grow in the dark for three months. Finally, the researchers dehydrate (使脱水) the material, and then evaluate its qualities.
They found that lower bormone levels lead to plant materials with more rounded, open cells of lower density (密度), while higher hormone levels contribute to the growth of plant materials with smaller but denser cell structures. Lower or higher density of cell structures makes the plant materials softer or more rigid, helping the materials grow with different wood-like characteristics. What’s more, it’s to be noted that the research process is about 100 times faster than the time it takes for a tree to grow to maturity!
Research of this kind is ground-breaking. “This work demonstrates the great power of a technology,” says lead researcher, Jeffrey Berenstab. “The real opportunity here is to be at its best with what you use and how you use it. This technology can be tuned to meet the requirements you give about shapes, sizes, rigidity, and forms. It enables us to grow’ any wooden product in a way that traditional agricultural methods can’t achieve.”

8 . My daughter will turn 17 in three months! As a parent, I feel the urgency (紧迫) to teach her important skills before she goes off to college.
Start the savings habit. Start to set aside money for the future now, while you are young.
Be careful with credit cards. When you go to college, you may find credit card companies often attract you to sign up for their credit cards. They will try to convince you that a credit card is like having free money for you to spend while you only pay the smallest amount each month.
Be a smart shopper. Plan ahead weekly by making a shopping list and stick to the list. Consider using recipes (食谱) that use low-cost, healthy materials.
A.Write down your needs and wants |
B.This idea of money can be very dangerous |
C.Get a part-time job when you're old enough |
D.Now put aside some money when you have any income |

9 . An Inuit-developed app, named SIKU after the Inuktitut for “sea ice”, allows local communities from Alaska to Greenland to connect traditional knowledge with scientific data to track changes in the environment, and make decisions about how to manage wildlife.
A group of Inuit elders and hunters from Sanikiluaq, Nunavut, thought up the idea for SIKU more than ten years ago to document and understand the changing sea ice they were seeing in southeastern Hudson Bay. The group turned to the local non-profit Arctic Eider Society (AES) to develop a web-based platform (平台).
Over the years, SIKU has developed, and recently, the elders saw that the platform could help address a familiar challenge: sharing knowledge with younger people who often have their noses in their phones. In 2019, SIKU was reintroduced as a full-fledged (全面发展的) social network — a platform where members can post photos and notes about wildlife sightings, hunts, sea ice conditions and more. The posts tell stories of hunting and traveling; the impacts of climate change and industrial activity; and the traditions, diets and illnesses of local animals.
Inuit communities are already using the app to inform important decisions. In 2021, for example, elders in Sanikiluaq were worried that the local reindeer (驯鹿) population had reduced, so the Hunters and Trappers Association used SIKU to survey hunters and look at recent reported harvest rates. The information led the association to close the hunt for a short time to reduce pressure on the population and to reintroduce hunting slowly when the number of reindeer increased.
Traditionally, Inuit communities shared this information orally (口头上地). “We have lived in the environment for centuries and know about the wildlife. Now armed with SIKU, information is documented in a way that other people will understand. The advantage of SIKU is that it’s part science and part Inuit knowledge and it supports community-driven research,” says Lucassie Arragutainaq, a co-founder of AES.
