UNIT 7 CAREERS(二)
Ⅰ.阅读理解
A(2025山东泰安三模)
In recent years,scientists have become aware of new problems associated with the mass production of microplastics,which can now be found on every part of the earth,including inside almost every person on the planet.Part of the problem is the difficulty and expense involved in recycling plastics,which makes it easier to throw them in the trash or the ocean.In a new study,the researchers in Switzerland have developed a way to break down plastics into their monomer(单体) substances,allowing for much easier and cheaper recycling.
Plastics are substances made up of large molecules(分子),which consist of smaller subunits called monomers.They are formed using a process called polymerization,which in essence combines the monomers into a single substance,namely plastic.Pulling them apart again has proven to be difficult and expensive,until now.
The new process involves placing the plastic substances in a chemical liquid and then shining a violet light on it as reactions in the liquid take place—no substance that promotes reactions is needed.The only caveats are that conditions in the container must be kept above 90℃,and the light must remain on the whole time.Once finished,the result is a container filled with monomers and other chemicals,which can be easily separated and recycled.
The technique was discovered by accident,so the team sought to explain why it worked so well.They found that the chemical,when exposed to the plastic substance,produced chlorine radicals(氯自由基) under the light.The radicals then pulled hydrogen atoms from seemingly random parts of the plastic substance backbone,causing it to break.Even better,when it broke,a new radical was formed,kicking off more reactions.
The researchers acknowledge that the reaction is slow,but also note that it has high output and that it is simple,easy and inexpensive to conduct.They suggest it could transform the recycling of plastics around the world.

A.To compare old and new recycling methods.
B.To stress the urgency of preventing plastic pollution.
C.To show the complexity of the new plastic-recycling technology.
D.To provide plastic knowledge for the new recycling method.
2.What does the underlined word “caveats” in paragraph 3 probably mean
A.Results. B.Requirements.
C.Advantages. D.Barriers.
3.What might the follow-up study focus on
A.Speeding the reactions in the liquid.
B.Reducing operating costs in the process.
C.Raising people’s awareness of recycling.
D.Increasing the temperatures in the container.
4.Which of the following serves as the best title for the text

D.Breakthrough:Plastic to Monomers
B(2025山东日照三模)
Scientists have recently developed a groundbreaking carbon capture material using metal-organic frameworks(MOFs) to achieve highly efficient carbon dioxide adsorption(吸附) under normal temperature and pressure,with energy consumption reduced by 90% compared to traditional methods.This breakthrough,led by a research team from Cambridge University,offers a revolutionary solution for industrial emission reduction and could become a critical component in global decarbonization efforts.
Traditional carbon capture methods rely on amine solution(胺溶液) adsorption,which requires high temperature and pressure,consuming significant energy and causing damage to equipment.In contrast,the new MOF-based material employs precisely engineered porous crystal structures to selectively adsorb CO2 under surrounding conditions.“The adsorption efficiency is 20 times higher than that of conventional materials,and the material can be reused over 1,000 cycles,” explained Alex Rodriguez,the lead researcher.Experimental data revealed that the material achieved a single capture efficiency of 98% in man-made flue gas from coal-fired power plants,far above industry averages.
The core innovation lies in the MOFs’ “molecular sieve” properties.Researchers finely adjusted the rate of metal nodes(节点) to organic linkers,creating 0.35-nanometer holes that precisely accommodate CO2 molecules while excluding nitrogen,oxygen,and other irrelevant components.Remarkably,material regeneration requires only normal-temperature cleaning,removing the need for energy-intensive heating during desorption.This approach theoretically reduces the cost of capturing one ton of CO2 to $15.
Beyond its technical superiority,the material boasts economic and environmental benefits.Made from sand-originated silicon and eco-friendly polymers,its production costs are 30% lower than traditional methods.Partnering with industrial giant Siemens,the team has launched pilot lines capable of mass-producing kilometer-long adsorbent sheets.“This isn’t lab-bound tech—we’re already installing systems in cement plants,” noted Alex Rodriguez.
Looking ahead,the technology holds promise for stabilizing renewable energy grids by storing solar or wind power as compressed CO2.Its closed-loop recyclability also removes electronic waste concerns.“A fireproof,paper-thin material that’s cheaper than conventional batteries,” summarized Alex Rodriguez.“As steelmakers and energy providers line up for licensing,this MOF-based breakthrough is likely to rewrite the rules of carbon management.”
5.What is paragraph 2 mainly about concerning MOF-based material
A.Its basic components.
B.Its excellent ability to capture CO2.
C.Its complex production process.
D.Its unique principle of regenerating CO2.
6.What do we know about MOFs’ “molecular sieve”
A.It requires high energy to operate.
B.It distinguishes CO2 from other gases.
C.It needs high temperatures to store CO2.
D.It creates large holes for gas capture.
7.What can be inferred about MOF-based technology according to Alex Rodriguez
A.It is still at the testing stage.
B.It raises concerns about energy waste.
C.It will replace conventional batteries.
D.It has a great potential for applications.
8.Which of the following is the best title for the text
A.Challenges of Carbon Capture
B.Innovations in Energy-saving Technology
C.MOFs:A Carbon Adsorption Breakthrough
D.MOFs:The Future of Clean Energy Storage

7.D 推理判断题。根据第四段中的“‘This isn’t lab-bound tech—we’re already installing systems in cement plants,’ noted Alex Rodriguez.”及第五段“Looking ahead...rewrite the rules of carbon management.”可知,Alex Rodriguez认为该技术已应用于工业场景且被多行业关注,具有广阔的应用潜力。
8.C 主旨大意题。通读全文,尤其是第一段中的“Scientists have recently developed a groundbreaking carbon capture material using metal-organic frameworks(MOFs) to achieve highly efficient carbon dioxide adsorption under normal temperature and pressure,with energy consumption reduced by 90% compared to traditional methods.”及全文对MOFs材料捕碳优势、原理和应用的介绍可知,“MOFs:碳吸附的突破”最能概括文章核心,适合作为最佳标题。

9.B 根据上文“Last Friday,Brinley Tatsey,holding the school record for the one-mile run,competed in a race.”可知,Tatsey在比赛中,所以她看到的应该是一同比赛的“竞争对手”。
10.A 根据上文“During it,she noticed a(n) gasping for air and breathing hard among the trees.”可知,她注意到一个竞争对手呼吸困难,结合下文“the severity of the situation and seeing no one else around”可知,此处指的是Tatsey看到对方的状况,“意识到”情况很严重,所以才决定去帮忙。
11.C 根据下文“reached for her inhaler”可知,Tatsey去帮助了对方,所以此处表示她“决定”去帮忙。
12.A 根据上文“ the severity of the situation and seeing no one else around,Tatsey to assist”可知,Tatsey停下来帮助对手,这一行为会“花费”她的比赛时间。故选A项。
13.D 根据上文“gasping for air and breathing hard”可知,对方呼吸困难,Tatsey拿吸入器是希望它能让对方的状况得到“缓解”。
14.B 根据上文“She reached for her inhaler,hoping it would provide some .”可知,Tatsey帮助对方,结合下文“After seeing that,Tatsey returned to her race.”可知,此处表示女孩在得到“妥善照顾”后情况良好。in good hands为固定短语,意为“得到妥善照顾”。
15.C 根据下文“about her uncharacteristically slow finish”以及“Tatsey said,‘I was just slow today.’”可知,母亲是对她成绩慢这件事进行“询问”。
16.A 根据下文“I was just slow today”可知,她没有提及帮助人的事情,只是“简单地”解释了一下。
17.D 根据上文“ the severity of the situation and seeing no one else around,Tatsey to assist,though she knew that it would likely her time.”可知,Tatsey在比赛中不顾可能要耽误的时间停下来帮助对手,这是一种“无私”的行为。
18.B 根据下文“Moved by Tatsey,he sent a letter to the Heart Butte athletic department”可知,这位观众被Tatsey的行为感动并写信说明情况,所以他是“目睹”了整个事件。
19.C 根据上文“Tatsey’s might have gone unnoticed but for a viewer from another school,who the entire event.”可知,有位观众目睹了Tatsey的无私行为,结合“Moved by Tatsey”可知,这位观众被感动,所以写信赞扬的是她的“行为”。
20.D 根据上文“he sent a letter to the Heart Butte athletic department”可知,观众是在信中表达对Tatsey的赞扬,所以此处表示“写道”。
21.B 根据上文“During it,she noticed a(n) gasping for air and breathing hard among the trees.”可知,这位运动员呼吸困难,处于“陷入困境的”状态。
22.A seek for寻求;show off炫耀;turn down拒绝;worry about担心。根据上文“When her mother,Gina Dosch, about her uncharacteristically slow finish after the competition,Tatsey said,‘I was just slow today.’”可知,Tatsey面对母亲询问只是简单解释,没有提及帮助人的事情,由此可知,此处指的是她没有“寻求”赞扬。
23.C 根据下文“The school community applauded her not just for her athletic competence but for her character and empathy.”可知,学校全体师生不仅为她的运动能力喝彩,更为她的品格和同理心而鼓掌,由此可推断,此处指的是学校为了表达对Tatsey的敬意,“赠送”给她一份纪念品。
