B(此篇精读)
(2025·湖南湘西州高二上期末)
Many previous studies have indicated that frequent walking was associated with a lower risk of developing type 2 diabetes(糖尿病) in the general population，in a way that those with more time spent walking per day were at a lower risk.But their findings haven’t offered much guidance on the best habitual walking speed needed to lower diabetes risk.
语篇解读　本文是一篇说明文。文章通过介绍一些研究结果讲述了降低糖尿病风险的简单方法——步行。
A new study’s authors reviewed 10 previous studies conducted between 1999 and 2022，which assessed(评估) the links between walking speed and the development of type 2 diabetes among adults from the United States，the United Kingdom and Japan.After a follow-up period of eight years on average，compared with those who took easy or casual(休闲的) walking (less than 2 miles per hour)，those who walked at an average or normal pace (2 to 3 miles per hour) had a 15% lower risk of developing type 2 diabetes，the researchers found.Walking at a “fairly quick” pace (3 to 4 miles per hour) meant a 24% lower risk than those who easily or casually walked.And quick walking(more than 4 miles per hour) had the biggest benefit：a 39% reduction in risk.
The overall message is that walking is an important way to improve your health.It may be true that walking faster is even better.But given the fact that most Americans do not get sufficient walking in the first place，it is most important to encourage people to walk more as they’re able to.
If you want to challenge yourself，however，using a fitness tracker—via a watch or smartphone app—can help you measure and maintain your walking pace，experts said.If you can’t get a fitness tracker，an easy alternative for tracking exercise intensity(强度) is the US Centers for Disease Control and Prevention’s “talk test”，which relies on understanding how physical activity affects heart rate and breathing.If，while walking，you’re able to talk in a labored voice but not sing，your pace is probably quick.
4.How did the researchers get the new findings
A.By studying former research.
B.By interviewing volunteers.
C.By carrying out an experiment.
D.By conducting an online survey.
细节理解题。根据第二段的“A new study’s authors reviewed 10 previous studies conducted between 1999 and 2022...the United Kingdom and Japan.”可知，研究人员通过研究以前的研究获得新发现。故选A。
解析
√
5.Which type of walking is the best for reducing diabetes risk
A.Easy walking. B.Quick walking.
C.Average walking. D.Casual walking.
细节理解题。根据第二段的“And quick walking (more than 4 miles per hour) had the biggest benefit：a 39% reduction in risk.”可知，快速步行最能减少糖尿病风险。故选B。
解析
√
6.What matters most to Americans in diabetes prevention
A.Buying a fitness tracker.
B.Avoiding eating too much.
C.Following the “talk test” rule.
D.Walking as much as possible.
细节理解题。根据倒数第二段的“But given the fact that most Americans do not get sufficient walking in the first place，it is most important to encourage people to walk more as they’re able to.”可知，对于美国人来说，预防糖尿病最重要的是尽可能地多走路。故选D。
解析
√
7.What is the best title for the text
A.Walking：the Secret to Physical Health
B.Walking：the End of Diabetic Patients’ Worries
C.Walking：a Simple Way to Reduce Diabetes Risk
D.Walking：an Effective Treatment for Diabetes
标题归纳题。根据第一段首句并纵观全文可知，文章主要讲述了走路对降低糖尿病风险是有益的，并建议多走路。因此推断C项“步行——降低糖尿病风险的简单方法”为最佳标题。故选C。
解析
√
1.be associated with与……有关/有联系
2.habitual adj.习惯性的；惯常的
3.follow-up(合)＝follow＋up adj.后续的
4.on average平均
5.labored adj.吃力的；费劲的
词汇积累
But given the fact that most Americans do not get sufficient walking in the first place，it is most important to encourage people to walk more as they’re able to.
分析：Given为介词，意为“考虑到”，the fact后面跟that引导的同位语从句；it为形式主语，to encourage people to walk more是真正的主语，as they’re able to为方式状语从句。
翻译：但考虑到大多数美国人一开始就没有进行足够的步行，最重要的是鼓励人们尽可能多地走路。

(2025·湖南湘西州高二上期末)
Many previous studies have indicated that frequent walking was associated with a lower risk of developing type 2 diabetes(糖尿病) in the general population，in a way that those with more time spent walking per day were at a lower risk.But their findings haven’t offered much guidance on the best habitual walking speed needed to lower diabetes risk.
A new study’s authors reviewed 10 previous studies conducted between 1999 and 2022，which assessed(评估) the links between walking speed and the development of type 2 diabetes among adults from the United States，the United Kingdom and Japan.After a follow-up period of eight years on average，compared with those who took easy or casual(休闲的) walking (less than 2 miles per hour)，those who walked at an average or normal pace (2 to 3 miles per hour) had a 15% lower risk of developing type 2 diabetes，the researchers found.Walking at a “fairly quick” pace (3 to 4 miles per hour) meant a 24% lower risk than those who easily or casually walked.And quick walking(more than 4 miles per hour) had the biggest benefit：a 39% reduction in risk.
The overall message is that walking is an important way to improve your health.It may be true that walking faster is even better.But given the fact that most Americans do not get sufficient walking in the first place，it is most important to encourage people to walk more as they’re able to.
If you want to challenge yourself，however，using a fitness tracker—via a watch or smartphone app—can help you measure and maintain your walking pace，experts said.If you can’t get a fitness tracker，an easy alternative for tracking exercise intensity(强度) is the US Centers for Disease Control and Prevention’s “talk test”，which relies on understanding how physical activity affects heart rate and breathing.If，while walking，you’re able to talk in a labored voice but not sing，your pace is probably quick.
语篇解读　本文是一篇说明文。文章通过介绍一些研究结果讲述了降低糖尿病风险的简单方法——步行。
4．How did the researchers get the new findings
A．By studying former research.
B．By interviewing volunteers.
C．By carrying out an experiment.
D．By conducting an online survey.
答案　A
解析　细节理解题。根据第二段的“A new study’s authors reviewed 10 previous studies conducted between 1999 and 2022...the United Kingdom and Japan.”可知，研究人员通过研究以前的研究获得新发现。故选A。
5．Which type of walking is the best for reducing diabetes risk
A．Easy walking. B．Quick walking.
C．Average walking. D．Casual walking.
答案　B
解析　细节理解题。根据第二段的“And quick walking (more than 4 miles per hour) had the biggest benefit：a 39% reduction in risk.”可知，快速步行最能减少糖尿病风险。故选B。
6．What matters most to Americans in diabetes prevention
A．Buying a fitness tracker.
B．Avoiding eating too much.
C．Following the “talk test” rule.
D．Walking as much as possible.
答案　D
解析　细节理解题。根据倒数第二段的“But given the fact that most Americans do not get sufficient walking in the first place，it is most important to encourage people to walk more as they’re able to.”可知，对于美国人来说，预防糖尿病最重要的是尽可能地多走路。故选D。
7．What is the best title for the text
A．Walking：the Secret to Physical Health
B．Walking：the End of Diabetic Patients’ Worries
C．Walking：a Simple Way to Reduce Diabetes Risk
D．Walking：an Effective Treatment for Diabetes
答案　C
解析　标题归纳题。根据第一段首句并纵观全文可知，文章主要讲述了走路对降低糖尿病风险是有益的，并建议多走路。因此推断C项“步行——降低糖尿病风险的简单方法”为最佳标题。故选C。
[词汇积累] 1.be associated with与……有关/有联系 2.habitual adj.习惯性的；惯常的 3.follow-up 合 ＝follow＋up adj.后续的 4.on average平均 5.labored adj.吃力的；费劲的 [句式分析] But given the fact that most Americans do not get sufficient walking in the first place，it is most important to encourage people to walk more as they’re able to. 分析：Given为介词，意为“考虑到”，the fact后面跟that引导的同位语从句；it为形式主语，to encourage people to walk more是真正的主语，as they’re able to为方式状语从句。 翻译：但考虑到大多数美国人一开始就没有进行足够的步行，最重要的是鼓励人们尽可能多地走路。
Ⅳ.七选五阅读(共5小题；每小题2.5分，满分12.5分)
While many people might be quitting formal New Year’s decisions this year，others may mark a fresh start by deciding to make up for poor eating habits of the past. 1 Without a solid plan，you may fail quickly.So consider starting with these three easy ways to eat a healthier diet.
Aim for real food only. 2 Maybe it’s the whole thing (like a frozen dinner)，or maybe it’s just part of your meal (like the bottled dressing on your salad)．Think of where you can replace processed foods for healthier ones.For example，eat whole-grain pasta instead of enriched white-flour spaghetti.
Schedule your meals and snacks.Set times on your phone for three different meals and two snacks (if you need them)． 3 This might control your desires，reduce stress about when you’ll eat next，and cut down on the extra calories of unnecessary snacking—a real challenge if you’re close to a refrigerator all day while at home or work.
Reduce your portion sizes.If you’re like most Americans，you’re eating too much food.An easy way to carry out portion control：load your plate as you normally would，then put back a third or half of the food. 4
You don’t need to include all of these steps at one time；try one step per week.Write down what you’re eating and any thoughts or questions you have about the process. 5 Before long，you’ll have the confidence to attempt new steps.
A．Avoid having late-night meals or snacks.
B．Don’t eat in between these scheduled times.
C．Processed foods are linked with many diseases.
D．After a week，assess what worked and what didn’t.
E．You can also use a salad plate instead of a dinner plate.
F．Look at your plate and note what’s processed and what isn’t.
G．But this motivation is often focused on a diet that is too ambitious.
