Section Ⅲ Grammar and usage
[课时检测]
Ⅰ.阅读理解
A small robot that can change its shape and produce heat shows potential in targeting cancer cells and preventing internal bleeding.It can also be used for delivering drugs directly to tumors (肿瘤) or inaccessible areas within the human body.
Researchers developed a centimeter-sized robot inspired by pangolins (穿山甲).It is constructed with soft and magnetic (磁性的) materials, allowing the robot to change its shape.
To enable movement, shape shifting, and heat generation, the researchers applied magnetic fields to the robot's metal parts.By adjusting the frequency of these fields, the robot was able to heat up and give out heat into its surroundings.The team observed that the robot's body temperature could be over 70 ℃.
In addition, researchers used the robot's heat to deliver substances within a simulated (模拟的) stomach environment.They attached something simulating medicine capsules onto the robot, which dissolved upon heating, thereby releasing the goods.This technique holds promise for targeted drug delivery inside the body.
Researchers also tested the robot's ability to halt bleeding.They created wounds using a dead pig's stomach.By pumping blood through a small incision using a syringe, they simulated bleeding.Subsequently, the robot extended and covered the area, giving out heat to help stop bleeding.
According to researchers, the robot could potentially be employed for targeted destruction of tumor cells, reducing the need for exposing large amounts of tissue to radiation or chemicals.By raising the robot's temperature to a level unsafe for normal cells and keeping it in place for a few minutes, cancer cells can be killed.Researchers emphasize the high temperature sensitivity of the human body.

1.What can we infer about the small robot?
A.It has been put into use.
B.It is mainly used to deliver goods.
C.It draws inspiration from the natural world.
D.It can't be used without adding hard elements.
解析:选C 推理判断题。根据第二段中的“Researchers developed a centimeter-sized robot inspired by pangolins.”可知,这种小型机器人的研发灵感来自穿山甲,由此可知,该机器人的灵感来自自然界。
2.How do the researchers make the robot change shape?
A.By using heat. B.By using magnets.
C.By using radiation. D.By using chemicals.
解析:选B 细节理解题。根据第二段中的“It is constructed with soft and magnetic materials, allowing the robot to change its shape.”可知,这种机器人是由一种柔软的磁性材料做的;结合第三段中的“To enable movement, shape shifting, and heat generation, the researchers applied magnetic fields to the robot's metal parts.”可知,为了让这种机器人能改变形状,研究人员使用了有磁性的材料。
3.What does the underlined word “halt” in paragraph 5 mean?
A.Stop. B.Challenge.
C.Evaluate. D.Explore.
解析:选A 词义猜测题。根据第五段中的“Researchers also tested the robot's ability”可知,此处指的是研究人员要对该机器人的某种能力进行测试;结合下文中的“Subsequently, the robot extended and covered the area, giving out heat to help stop bleeding.”可知,这种机器人能够帮助止血,由此可知,该单词的意思应是“阻止”。
4.Which can be the best title for the text?
A.A Tiny Robot Will Be Used in Medicine
B.Scientists Will Make Robots Give out Heat
C.A Small Robot Was Made to Deliver Goods
D.Doctors Have Used Tiny Robots to Cure Tumors
解析:选A 标题归纳题。首段提到,研究人员设计了一种可以改变形状的小型机器人,这种机器人可以靶向杀灭肿瘤细胞,还能给伤口止血,具有潜在医学应用前景,进而在下文中对该机器人的制作灵感以及该机器人的功能进行介绍。故A项“一种将被应用在医学上的小型机器人”适合作文章标题。

语篇解读:本文是一篇说明文。文章主要介绍了英国卡迪夫大学研究员用人工智能来鉴定帕金森病早期症状。
20.to analyse 考查非谓语动词。分析句子结构可知,空处在句中作目的状语,应用不定式。
21.tracking 考查非谓语动词。介词by后应加动名词作宾语。
22.that/who 考查定语从句。空处引导定语从句,且在从句中作主语,先行词为those people,指人,故填关系代词that/who。
23.a 考查冠词。此处表示“一种实用的工具”,所以应用不定冠词,表泛指,且 practical以辅音音素开头,故填a。
24.gathered 考查非谓语动词。句子谓语动词是are needed,这里other data与gather之间为被动关系,所以应填过去分词作后置定语。
25.devices 考查名词复数。 device表“设备”,为可数名词;根据上文“30% of the UK population”可知,此处应用复数形式作宾语。
26.reliable 考查形容词。 根据and前的“cheap”以及句意可知,此空应填形容词作定语,修饰后面的名词way。
27.from 考查介词。 distinguish ...from ...表示“区分……与……”,为固定搭配。
28.will make/will be making 考查时态。此处表示2027年将有近2.3亿人充分利用可穿戴设备。根据时间状语“in 2027”可知,此空可用一般将来时或者将来进行时。
