Nashville Sail Camp
Nashville Sail Camp is a learntosail camp for all levels of sailors.Along with sailing, campers will learn valuable problemsolving and creative thinking techniques.They spend their days on shore and on the water, and will come home with plenty of handson sailing experience.
Place | Weeklong Day Camp at Hamilton Creek Marina on Percy Priest Lake |
Time | 9:00 am-4:00 pm, Monday-Friday |
Ages | 7-17 |
Price | * $485/week * An extra $65/week (Weekly Extended Care: dropoff as early as 7:45 am and pickup as late as 5:15 pm for car rider campers) |
All groups are coached by US Sailing qualified instructors and helped by camp counselors (顾问) and junior counselors.Each day includes lessons proper for each learning level.
Option 1
Our youngest and smallest campers will take the helm (舵柄) for the first time, learning the basics of sailing in pairs on board their boats.
Option 2
Beginners aged 9 and up as well as Option 1 graduates will increase their skill level at the helm of an Option sailboat.Campers are encouraged to learn singlehanded sailing after mastering sailing in pairs.
Sunfish
Sailors aged 11 and up will explore the waters on a leisure sunfish boat, one of the world's most popular day

sailing boats.Starting off in pairs to increase confidence and get practice with a friend on board, campers are encouraged to try singlehanding the boat by the end of the week.Sunfish campers spend most of their time on the water throughout the week.
Tips
● Campers must be comfortable in boats and have strong swimming skills.
● All campers are required to wear life jackets in and around the boats and water.

[语篇解读]本文是一篇应用文。文章介绍了Nashville Sail Camp的营地活动。
1.How much should a camper pay if he wants to be picked up at 5:15 pm?
A.600 dollars. B.485 dollars.
C.550 dollars. D.65 dollars.
解析:选C。细节理解题。根据表格中Price部分“* $485/week (每周485美元)”及“* An extra $65/week (Weekly Extended Care: dropoff as early as 7:45 am and pickup as late as 5:15 pm for car rider campers)”可知,如果露营者想在下午5点15分被接走,他应该支付485加65等于550。故选C。
2.What are Sunfish campers encouraged to do at the end of their camp?
A.Master sailing in groups.
B.Sail by themselves.
C.Explore the waters in pairs.
D.Make friends with other campers.
解析:选B。细节理解题。根据Sunfish部分的“Starting off in pairs to increase confidence and get practice with a friend on board, campers are encouraged to try singlehanding the boat by the end of the week.”可知,建议Sunfish露营者在露营结束时自己航行。故选B。
3.What is a must for campers?
A.Wearing a certain life jacket.
B.Learning about sailing beforehand.
C.Staying comfortable in camps.

(2025·湖南长沙高二上期末)A team of AI researchers at Microsoft, working with colleagues from the Pacific Northwest National Laboratory(PNNL), has used AI to develop a battery that uses less lithium (锂).
Lithium batteries have become the industry standard for electronic devices and electric vehicles and are expected to play a major role in the change to green power.But lithium is expensive, which has led multiple teams across the globe to look for alternatives.In this new effort, the research team looked for ways to reduce the amount of lithium used in batteries.
This would normally take a long time because of the detailed approach required.To reduce the workload and the time needed to process millions of alternatives, the researchers turned to AI.Noting that AI applications are good at using massive amounts of data to learn how to do things, the researchers designed one that could study millions of materials that might be added to a lithium battery to replace some amount of the lithium and test the results for factors such as stability and how a battery using a given material would behave.
Using this approach, the research team reduced the list of possible alternatives to just a few hundred possibilities.They then turned to materials scientists at PNNL for advice on how to reduce the possibilities even further.The scientists suggested adding more specific screening criteria and more testing rounds.After adopting that advice, the team arrived at a promising alternative and an approach that involved replacing approximately half of the lithium atoms in a battery with sodium (钠) atoms.
After using the new approach to build a working battery, the researchers found it had lower conductivity (导电性) than needed—but they also believe that there is room for improvement.They plan to continue working on the approach and the process they used to find their solution, which they suggest could eventually solve other types of material processing problems.
[语篇解读]本文是一篇说明文。文章主要说明了微软的一组人工智能研究人员与太平洋西北国家实验室(PNNL)的同事合作,利用人工智能开发了一种使用更少锂的电池。
4.Why did the research team want to develop a battery that uses less lithium?
A.To reduce carbon emissions.
