)6.(2023·湖北荆州)—What did the shopkeeper say to you?—She asked me
if I preferred that T-shirt
.A.when did the shop close
B.if I preferred that T-shirt
C.what else I will buy
D.where did I see the style
答案
6. B 【点拨】宾语从句使用陈述句语序，排除选项A和D。又因为主句“She asked me”是一般过去时，从句也要用相应的过去时态。故选B。
解析
【分析】
这道题考查宾语从句的用法，解题时可以分两步走：第一步先排查语序，宾语从句必须使用陈述句语序，也就是从句的主语要放在谓语动词前面，不能出现助动词提前的疑问语序，观察选项A和D都把助动词did放到了主语前面，是典型的疑问语序，直接排除这两个选项。第二步排查时态呼应规则，主句的谓语动词是asked，属于一般过去时，按照宾语从句的时态规则，从句要使用和过去相关的对应时态，剩下的B和C选项里，C选项的will buy是一般将来时，属于现在范畴的时态，不符合时态要求，而B选项的preferred是一般过去时，完全符合规则，因此可以确定正确答案。
【解析】
宾语从句需要满足两个核心要求：
1. 语序要求：必须使用陈述句语序，即“连接词+主语+谓语+其他成分”，选项A（when did the shop close）和选项D（where did I see the style）都是助动词did提前的疑问语序，不符合要求，直接排除A、D。
2. 时态呼应要求：当主句的谓语动词为一般过去时（本题主句谓语是asked，为一般过去时），宾语从句需要使用对应的过去相关时态。选项C的what else I will buy是一般将来时，属于现在范畴的时态，和主句时态不匹配，排除C。
选项B的if I preferred that T-shirt既符合陈述句语序，动词preferred也为一般过去时，完全符合规则。
【答案】
B
【知识点】
宾语从句陈述语序，宾语从句时态呼应
【点评】
本题是中考英语典型的宾语从句基础考题，考点清晰明确，只要牢记宾语从句语序、时态两大核心判定规则，按照先查语序再核对时态的顺序解题，就能快速排除错误选项得到正确答案，属于宾语从句考点的必拿分题型。

解析
【分析】
做这类语篇选词填空题，首先要通读完整语篇，明确本文核心是介绍太空存在的各类危险因素以及人类对太空的探索，先把握整体语境逻辑。接下来逐个空格结合前后文的语义、固定搭配、语法规则，对给出的备选词进行正确形式转换：
1. 第一空和后文的dangerous并列作表语，需要把amaze转换为修饰事物的形容词，对应“太空既令人惊叹又危险”的语义；
2. 第二空前后是danger和success两个并列名词，需要用短语连接二者，表达宇航员同时面对危险和成功的含义；
3. 第三空对应固定搭配in danger of，要把形容词dangerous转换为名词形式；
4. 第四空在定冠词the后作主语，要把形容词harmless转换为对应名词，表达辐射的危害的含义；
5. 第五空有时间标志so far，要用现在完成时，同时主语和动词是被动关系，要使用现在完成时的被动结构；
6. 第六空后文多次提到太空垃圾是太空的重大危险，直接对应备选词rubbish即可；
7. 第七空是there be句型的后置定语，人造物体和飞行动作是主动关系，用现在分词作定语；
8. 第八空对应固定搭配in size，表达尺寸大小的含义；
9. 第九空前后是让步转折逻辑，用让步连词连接两个句子；
10. 第十空符合help do sth的用法，把名词improvement转换为动词improve，表达改善太空环境的含义。
【解析】
逐空推导过程：
1. 空1：此处需要形容词作表语修饰space，amaze的形容词形式amazing意为“令人惊叹的”，符合“太空不仅令人惊叹还十分危险”的语境，填amazing。
2. 空2：此处需要连接两个并列名词danger和success，as well as意为“和，也”，符合“宇航员同时面对危险与成功”的语义，填as well as。
3. 空3：固定搭配in danger of 意为“面临……的危险”，将形容词dangerous变为名词danger，填danger。
4. 空4：定冠词the后需要接名词作主语，harmless对应的名词harm意为“危害”，符合“辐射的危害直到他们的孩子甚至孙辈出生才会显现”的语义，填harm。
5. 空5：时间状语so far是现在完成时的标志，主语effective medicine和动词find是被动关系，因此用现在完成时的被动语态has been found，填has been found。
6. 空6：后文重点介绍太空垃圾的危害，此处主语为太空垃圾，直接填备选词rubbish，填rubbish。
7. 空7：此处作后置定语修饰man-made things，二者是主动的“飞行”关系，用现在分词flying，填flying。
8. 空8：固定搭配in size意为“在尺寸上”，符合“每个碎片至少4毫米大小”的语义，填in size。
9. 空9：前后句为让步转折关系，句首首字母大写，填Although，表“尽管太空十分危险，它仍然吸引了地球上的很多人”。
10. 空10：help后接动词原形构成help do sth结构，将名词improvement变为动词improve，表“改善太空环境”，填improve。

五、阅读理解。(2023·江苏南京建邺区一模)
The world is full of amazing things. Let's see China's amazing technology!
In our modern age，we do not think much about how our technology works. We are so used to tapping the phone screen to get a map of our location. But how do our phones know where in the world we are and in which direction we are going? It is all thanks to the satellites in space that help our phones calculate our position. Depending on where you are around the world，your phone may be receiving data from different systems. In Europe，people have the Galileo system. In Russia，they have GLONASS. In the USA，people use GPS. China，meanwhile，has the BeiDou Navigation Satellite System(BDS).
The BDS in operation today is more advanced than the first version(版本) of the system which was sent into space in 2000. The present version has better technology and more satellites. The system is not finished，though. When it is completed，there will be lots of BDS satellites. In the future，those satellites will allow us to discover the position of objects with millimetre accuracy(精确度)：That is ten times more accurate than GPS.
Even though more satellites are being added to the system，the BDS has already been put into use. Over 40,000 Chinese fishing boats are using the system now. These boats are very helpful in search and rescue operations(营救行动) at sea. They are able to communicate with support services on land as well as give the exact locations of ships in trouble.
The BDS is being used on land as well. Of course，it's not hard to imagine how the system is helping police and firefighters do their jobs. Agriculture is another area where there are applications for the system. Farmers are able to put the data to good use when operating smart farming equipment. For example，the BDS can be used to control driverless tractors as they turn up in the fields. Farmers are also using drones(无人机) to check the health of crops and spread seeds over fields.
Although the BDS is of Chinese origin(起源)，the developers have said that “China's BeiDou is the world's BeiDou”，and they are actively developing international cooperation. Developers predict that the system will not only grow in popularity within China，but overseas as well. And when the system is complete and fully operational in the years to come，the BDS will undoubtedly bring lots of advantages to China and the rest of the world.

解析
【分析】
拿到这篇阅读理解，首先先通读全文，明确文章核心是介绍中国北斗导航系统的发展历程、当前落地应用场景以及未来的发展前景。接下来逐题对应考点梳理思路：
1. 第1题是词义猜测题，先定位划线词所在语境，结合前文提到手机要确定自身位置，需要卫星辅助，再对照给出的4个词典释义，匹配符合“通过数据推导位置”的含义即可选出答案。
2. 第2题问写作手法，回到第三段，找段落里的对比对象：把现在运行的北斗系统和2000年发射的初代北斗版本做差异对比，就能判断出作者是通过对比不同阶段的状态来展现北斗的变化。
3. 第3题是推理判断题，把每个选项逐一和原文内容比对，排除和原文表述矛盾的错误选项，剩下符合逻辑推导的正确选项。
4. 第4题判断文章出处，全文围绕前沿科技北斗展开，对应内容所属的书籍类别就能得出答案。
5. 第5题选最佳标题，结合全文既介绍北斗现有应用，也重点展望未来发展趋势的核心主旨，匹配最贴合的标题即可。
【解析】
1. 定位划线词"calculate"所在句："It is all thanks to the satellites in space that help our phones calculate our position."，结合后文提到手机接收不同系统的数据来确定自身位置，该词在这里表示“计算位置”，对应给出的词典释义④“根据数据或线索算出结果”，因此选D。
2. 第三段将当前投入使用的北斗系统和2000年发射的初代北斗系统进行对比，从技术先进性、卫星数量、定位精度等维度展现二者的差异，是通过对比不同阶段的条件/状态来体现北斗系统的变化，因此选D。
3. 逐一核对选项：
A选项：原文最后一段说明北斗未来才会在海内外普及，并非已经流行，表述错误；
B选项：第二段明确提到不同国家使用不同的定位系统，欧洲用伽利略、俄罗斯用格洛纳斯、美国用GPS，并非全球所有人使用同一套定位系统，表述错误；
C选项：原文最后一段说明北斗完全建成并投入全面运行后，会给中国和全世界都带来诸多益处，可以推得数年后全球都能受益于北斗，表述正确；
D选项：文中仅提到北斗在渔业、警务、农业等特定领域应用，并未说明它已经成为日常通用的通讯方式，表述错误。
因此选C。
4. 全文围绕中国前沿科技北斗导航系统展开介绍，属于科技类内容，最可能出现在科学书籍中，因此选C。
5. 全文既介绍了北斗的现有发展和落地应用，也重点展望了它未来完全建成后给全球带来的价值，突出北斗作为先进科技的发展潜力，"Next Up, the BDS（即将登场，北斗）"最贴合主旨，其余选项含义均不符合文章内容，因此选A。

【点评】
本篇阅读选取我国北斗导航系统作为主题，既覆盖了词义猜测、细节查找、推理判断、主旨选择等常规阅读考点，也能让学生了解我国前沿科技成就，题目设置梯度合理，大部分题目可以通过精准定位原文信息直接得出答案，少量推理类题目需要结合全文内容排除干扰项，能够有效锻炼学生的信息提取能力和逻辑推导能力。
