语法归纳
【语境感悟】
阅读以下有关“科学”的短文,感知加黑部分,并回答其后的问题。
The biggest attraction of scientific exploration is ①that it
holds countless secrets waiting to be discovered. It is also
②what drives scientists to constantly push the boundaries of
human knowledge. Moreover, scientific exploration is ③where
new technologies and innovations are born. The doubt in
many people's minds is ④whether there is life on other
planets. Another mystery scientists often study is ⑤why some
species evolve faster than others. A key focus of medical
research is ⑥how we can develop better treatments for
diseases. What remains unclear sometimes is ⑦which approach
will work best in complex experiments.
【自主发现】
以上语段中,①、②、③、④、⑤、⑥、⑦句均为______从句;其
中that,whether为__________,在从句中不作成分;what,which为
__________;where,why,how为__________。
表语
从属连词
连接代词
连接副词
Predicative clauses
(表语从句)
在复合句中,位于系动词之后作表语的从句叫作表语从句。表语
从句常用以下引导词:
类别 例词 说明
从属连词 that,whether 两者在从句中都不作成分,that无实
义,whether意为“是否”,通常不能用if替换
连接代词 who, whose, what, which等 在从句中作主语、宾语、表语、定语
(who除外)
连接副词 when, why, where, how 在从句中作时间、原因、地点、方式状语
其他连接词 because 主句主语不用reason
as if/as though 表语从句表示的情况发生的可能性较小时
常用虚拟语气
如:The most important thing is that we should find enough
water for the sheep.
最重要的事是我们应为羊找到足够的水。
The doubt is who has taken away the valuable painting.
疑问是谁拿走了那幅珍贵的画。
The black clouds are gathering. It looks as if it is going to
rain.
乌云正在聚集。天看起来好像要下雨了。
注意:
1.that,why,because引导表语从句的区别:
(1)表示原因的名词(reason,cause)作句子主语时,其后的表语从句常用
that引导,不可用because。 如:
The reason why he was late was that he missed the first bus
this morning.
他迟到的原因是他今天早晨错过了首班公共汽车。
(2)because引导的表语从句常用于“That's because…”结构中,说明产
生上述结果的原因,表示前果后因;why引导的表语从句说明由上述原
因导致的某种结果,表示前因后果。 如:
I was late for school this morning. That's because I stayed up
too late last night. (果→因)
今天早晨我上学迟到了,那是因为我昨晚熬夜太晚了。
I stayed up too late last night. That's why I was late for school
this morning. (因→果)
我昨晚熬夜太晚,那就是我今天早晨上学迟到的原因。
2.表语从句中的虚拟语气
当主语是表示“建议、命令、要求、计划(suggestion,advice,proposal,
order,command,request,requirement,demand,plan)”等的名词时,
表语从句应该用虚拟语气,即从句谓语用“should+动词原形”形式,
should可以省略。 如:
My suggestion is that we (should) set off early tomorrow.
我的建议是我们明天早点儿动身。

Ⅳ 阅读理解(每小题2.5分,满分10分)
Laughter comes in many forms, from a polite chuckle to an
infectious howl of amusement. Scientists are now developing an
AI system that can copy various forms of laughter accurately.
The team behind the laughing robot, Erica, say that the system
could improve natural conversations between people and AI
systems.

课后素养提升练
Dr Koji Inoue, lead author of the research from Kyoto
University, highlights empathy (共情) as a crucial aspect of
conversational AI, suggesting laughter sharing as a means for
robots to connect with users. To achieve this, Inoue and his
team gathered data from over 80 speed-dating dialogues
between male students and Erica, initially operated by amateur
actors.
Dialogue data labeled for individual, social, and joyful
laughter was used to train an AI system to identify and produce
1

fitting laughter responses. Based on the audio files, the
algorithm (算法) learned their subtle differences, aiming to
imitate social laughs subtly and hearty laughs empathetically.
“Our biggest challenge in this work was identifying the
actual cases of shared laughter,” explained Inoue, emphasizing
the need for careful categorization. Erica's “sense of humour”
was tested with four dialogues, integrating the new shared-
laughter algorithm. These were compared to cases where Erica
didn't laugh or emitted social laughs upon detecting laughter.

The clips were played to 130 volunteers who rated the
shared-laughter algorithm highly for empathy and naturalness.
The team believed laughter could imbue robots with unique
character traits, including conversational behaviours like laughter,
eye gaze, gestures, and speaking style. However, Inoue
acknowledged it could take over 20 years to have a “casual
chat with a robot like we would with a friend”.
Professor Sandra Wachter, of the Oxford Internet Institute at
the University of Oxford, said, “One of the things I'd keep in
1

mind is that a robot or algorithm will never be able to
understand you. It doesn't understand the meaning of laughter.
They fail to feel, but they might get very good at making you
believe they understand what's going on.”

Ⅴ 阅读七选五(每小题2.5分,满分12.5分)
Physicist and Nobel Prize winner Richard Feynman
developed a clever learning method known as the Feynman
Technique (费曼学习法). It involves explaining what you're
learning to others. By teaching what you've learned from
memory, you engage in active recall.1.___ It also ensures that
you understand the topic, because you can only explain an idea
if you truly understand it. The technique is made up of four
repeatable steps.
A
1
2
3
4
5
To begin, choose a concept or topic you wish to fully
understand.2.___ The more interested you are, the faster you'll
grasp it. Moreover, a personally interesting topic will keep you
motivated and engaged.
3.___ Write notes and explain it in a way that makes sense
to a five-year-old. If you'd rather avoid actually teaching
someone, you can just teach it to an imaginary audience. But it
works much better if you use a real person. They'll be able to
let you know when something isn't clear.

While teaching you may discover gaps in your
understanding.4.___ Review your notes, reread books, or seek
external help to ensure you have a complete understanding of
the context before moving forward.
F

5
Now that you fully grasp the concept, test your
understanding by trying to teach it to another person. This will
help you identify any remaining areas of uncertainty you need
to revisit.
The Feynman Technique is a great way for kids and grown-
ups to learn. It is mentally demanding. You need to actively
think about the problem instead of passively reading or listening
to someone else. 5.___

A.This helps the information stick in your mind better.
B.Teach it to a five-year-old, who would give you direct
feedback.
C.Once you have chosen a topic, you can teach it to someone
else.
D.Your curiosity about it will determine the pace of your
learning.
E.Active engagement plays a key role in promoting deeper
learning.

F.When this happens, refer back to the original material for the
missing pieces.
G.However, with great efforts in mastering this method, your
