⑦ Grammar｜Modal verbs工程用法
今天开始系统整理：
may / should / must
这三个你在工程英语里会天天遇到。
may
表示：
可能
不是确定。
Further investigation may be required.
可能需要进一步调查。
should
表示：
应该 / 建议 / 一般要求
Engineers should assess the damage.
工程师应评估损伤。
must
表示：
必须
语气明显强于should。
Critical defects must be repaired immediately.
严重关键缺陷必须立即维修。
练习6题
选择：
may / should / must
1
Minor defects ___ only require monitoring.
2
Engineers ___ record all significant observations clearly.
3
A critical safety hazard ___ be addressed immediately.
4
Further investigation ___ be necessary if the cause remains uncertain.

答案
答案
may
should
must
may

must
今天真正理解：
may = possibility should = recommendation / expected practice must = obligation

Defect Monitoring and Maintenance Decisions
Not every structural defect requires immediate repair. Minor cracks, small areas of corrosion, or limited local damage may remain stable for long periods. In these cases, regular monitoring may be more appropriate than immediate remedial work.
Monitoring allows engineers to determine whether a defect is stable, improving, or continuing to develop. Measurements, photographs, and inspection records can be compared over time. Progressive increases in crack width, deformation, settlement, or corrosion may indicate that the structural condition is deteriorating.
The required response depends on the severity, rate of change, and possible consequences of the defect. Minor stable defects may require only continued monitoring, while significant or progressive damage may require maintenance, repair, strengthening, or further investigation.
Engineers should clearly record the reason for each maintenance decision. The records should identify what has been observed, how the condition has changed, what action is recommended, and when the structure should be inspected again.

每段一句中文。
参考：
P1
并非所有缺陷都需要立即维修，轻微稳定缺陷可以先监测。
关键词：
minor defects / stable / monitoring
P2
监测用于判断缺陷是否持续发展。
关键词：
monitoring / compare / progressive
P3
处理方式取决于缺陷严重程度和发展速度。
关键词：
severity / rate / response
P4
工程师应记录维护决策及后续检查要求。
关键词：
records / action / inspection

⑪ 今日长难句
Minor stable defects may require only continued monitoring, while significant or progressive damage may require maintenance, repair, strengthening, or further investigation.
主句1
主语：
Minor stable defects
谓语：
may require
宾语：
continued monitoring
minor和stable都修饰：
defects
only强调：
只需要监测
while
这里不是单纯的“当……时候”。
这里表示：
而、然而、相比之下
第二分句
主语：
significant or progressive damage
谓语：
may require
宾语：
maintenance, repair, strengthening, or further investigation
最短逻辑
Minor defects may require monitoring, while serious damage may require action.
自然翻译：
轻微且稳定的缺陷可能只需要持续监测，而明显或持续发展的损伤则可能需要维护、维修、加固或进一步调查。
⑫ 阅读题 Part A
Q1
Why may some minor defects not require immediate repair?
Q2
What can monitoring help engineers determine?
Q3
What changes may indicate that structural condition is deteriorating?
Q4
What factors determine the required response to a defect?
Q5
What may significant or progressive damage require?
Q6
What should engineers record when making a maintenance decision?
⑬ Rewrite｜2题
1
Engineers monitor minor defects regularly.
改被动：
Minor defects…
2
Inspection records help engineers identify changes.
改成：
Engineers are helped…
这句会稍微别扭，所以除了直接被动，再想一下工程英语里更自然的改法。
参考
参考
1
Minor defects are monitored regularly by engineers.
工程写作更自然：
Minor defects are monitored regularly.
2
机械被动：
Engineers are helped by inspection records to identify changes.
语法可以，但非常不自然。
更自然：
Inspection records allow engineers to identify changes.
这题的目的就是让你知道：
不是所有主动句都值得强行改被动。
