(2025·潍坊市高二下期末)
Early in the autumn of 1674,Henry Oldenburg,secretary of the Royal Society in London,received an extraordinary letter.Sent by Antonie van Leeuwenhoek,a draper from Delft in the Netherlands,it contained an unlikely-sounding claim.
Using a microscope of his own invention,van Leeuwenhoek had seen tiny creatures,invisible to the naked eye,living in lake water.Some of these “animalcules (微生物)” were so small,and he later estimated that 30 million of them would still be smaller than a grain of sand.
Royal Society fellows couldn’t believe it.Even with his most powerful instruments,the celebrated English microscopist Robert Hooke had never observed anything like the little creatures.
In fact,the Dutchman had developed far superior lenses to Hooke’s,and had discovered bacteria and protozoans (原生动物).By producing even smaller and more curved lenses—using a technique that he kept secret—van Leeuwenhoek was able to magnify objects up to 500 times.As well as discovering microorganisms,he was the first to see red blood cells.
In 1677,van Leeuwenhoek sent the Society further animalcule observations.Hooke eventually improved his own microscopes to the point where he,too,could see the tiny creatures.Three years later van Leeuwenhoek was made a fellow.
It was not until 1890,more than 160 years after van Leeuwenhoek’s death,that bacteria were linked with diseases.“Reading van Leeuwenhoek’s letters,you very much get the impression of somebody dazzled by what he was finding,” says Lesley Robertson,leader of the archives at Delft University’s school of microbiology.“He thought he’d found a whole new world—but he certainly never picked up on the connection with illness.”
【语篇解读】　本文是一篇说明文。文章主要介绍了列文虎克用自己制作的显微镜观察到微生物,使得把细菌和疾病联系在一起成了可能。
1.What did Antonie van Leeuwenhoek see with his own microscope
A.A letter.
B.Bacteria and protozoans.
C.Small animals in the water.
D.The element of water.

√
2.From the passage we can see ________.
A.van Leeuwenhoek knew the tiny creatures in the water had something to do with nature
B.van Leeuwenhoek discovered the little creatures earlier than Robert Hooke
C.van Leeuwenhoek was the first one to use the microscope
D.van Leeuwenhoek was the first one to know how to observe bacteria and protozoans
解析　推理判断题。根据第二段中的“Using a microscope...in lake water.”和第三段可知,列文虎克比胡克更早发现了这些微生物,因此B项正确,故选B项。
√
3.What does the underlined word “magnify” in the fourth paragraph mean
A.To clear away. B.To improve.
C.To collect. D.To make large.
解析　词义猜测题。联系全文以及画线词后的“up to 500 times”可知,列文虎克自己改良后的显微镜能把物体放大500倍,故选D项。
√
4.From the last paragraph we can see,when Antonie van Leeuwenhoek saw the tiny creatures,invisible to the naked eye,living in lake water,________.
A.he was overexcited
B.he knew he followed someone else’s discovery
C.he was a bit disappointed
D.his discovery was to lead a connection between bacteria and illnesses
解析　推理判断题。根据最后一段的“Reading van Leeuwenhoek’s... by what he was finding”可知,当时他对自己的发现是极度兴奋的,故选A项。

(2025·濮阳市高二下期末)
Researchers in the US are developing an app called FoodImage to handle the problem of food waste.This app is based on a previous app named SmartIntake,which measures food consumption by comparing photos taken before and after meals.
According to Corby Martin,a clinical psychologist at Pennington Biomedical Research Center,SmartIntake allows users to take photos of their plates before and after eating.These images are then sent to servers where researchers analyze the food for its calorie and nutrient content.Martin believes this photo comparison method can be adapted to measure how much food is left uneaten and ends up as waste.
“We fully expect that SmartIntake can measure food waste,but it needs to be improved to capture (捕捉) waste wherever it occurs,” says Martin.The goal is to measure not just leftovers but also waste produced during meal preparation and whether leftovers are ever consumed.This is important because,according to Brian Roe,a behavioral economist at Ohio State University,Americans waste about a quarter of the food they buy annually (about 40 million tons,which also means 1.5 million tons of food was thrown away every day),costing each family between $1,365 and $2,275.
FoodImage aims to provide researchers with exact data on when and how food waste occurs.For instance,if a household buys food in large amounts because it’s on sale,FoodImage could help determine if this leads to increased waste,advice against such buying will be possibly given.
Efforts to reduce food waste are gaining attention globally.The US Department of Agriculture and the Environmental Protection Agency have set a goal to halve America’s food waste by 2030.
The FoodImage project is currently at the research stage,which the researchers hope to complete by the end of the year.Martin and Roe think it will take 9 to 12 months to develop the final product once funding is solved.“If we can conduct studies that really point out how the different approaches affect household behaviors,then we can help prioritize which of these will deliver the biggest impact,” says Roe.“But you need good household-level data to accomplish that.”
【语篇解读】　本文是一篇说明文。文章主要介绍了美国研究人员正在开发的一款名为FoodImage的应用程序,该应用程序旨在解决食物浪费问题。
5.What do the figures in paragraph 3 indicate
A.The seriousness of food waste in the US.
B.The high living costs of American families.
C.How difficult it is for people to reduce food waste.
D.How useful SmartIntake is in measuring food waste.
解析　推理判断题。根据文章第三段“This is important because...costing each family between $1,365 and $2,275.”可知,这些数据表明美国人每年浪费大量食物,每个家庭为此付出高额成本,这充分体现了美国食物浪费问题的严重性,故选A项。
√
6.What is the main function of the FoodImage app
A.Raising people’s awareness of healthy eating.
B.Teaching people how to cook with less food waste.
C.Offering researchers detailed information on food waste.
D.Helping researchers to determine the food quality correctly.
解析　细节理解题。根据文章第四段“FoodImage aims to provide...how food waste occurs.”可知,FoodImage这款应用程序的主要目的是为研究人员提供有关食物浪费何时发生以及如何发生的确切数据,也就是为研究人员提供关于食物浪费的详细信息,故选C项。
√
7.What can we learn from the last paragraph
A.The FoodImage project is well received by the public.
B.Information from the household is important to the project.
C.The research stage of the project will take another 9 months.
D.Lack of money is the main problem for the project’s development.
解析　推理判断题。根据文章最后一段内容可知,需要通过研究指出不同方法对家庭行为的影响并确定哪种方法影响最大,这表明来自家庭层面的信息对于该项目很重要,故选B项。
√
8.What would be a suitable title for the text
A.Global Efforts to Reduce Food Waste
B.The Role of Hi-Tech in Managing Food Waste
C.FoodImage:A New Approach to Food Waste
D.SmartIntake:A Good Measure of Food Consumption
解析　标题归纳题。根据文章内容可知,文章开篇指出研究人员正在开发名为FoodImage的应用程序来解决食物浪费问题,接着介绍了其基于的SmartIntake应用,阐述了FoodImage旨在为研究人员提供食物浪费的确切数据,以及项目目前所处阶段等内容,全文围绕FoodImage 这一解决食物浪费的新途径展开。选项C符合文章主旨,故选C项。

【语篇解读】　本文是一篇说明文。文章主要介绍了上海博物馆为纪念意大利旅行家马可波罗举办的展览。
1.who　 [考查定语从句。此处引导的是一个非限制性定语从句,从句缺少主语,先行词为Marco Polo,指人,应用关系代词,故填who。]
2.death　 [考查词性转换。此处用所给动词的名词形式作介词of的宾语,故填death。]
3.named　 [考查非谓语动词。此处用非谓语动词作后置定语,修饰名词exhibition,动词name和逻辑主语exhibition是动宾关系,所以应用过去分词,故填named。]
4.started　 [考查动词的时态。根据空后的时间状语“in 1271-1295”可知,句子应用一般过去时,所以此处用所给动词的过去式,故填started。]
5.walking　 [考查非谓语动词。此处填非谓语动词,动词walk与其逻辑主语Marco Polo之间存在逻辑上的主谓关系,故此处用所给动词的动词-ing形式作伴随状语,故填walking。]
6.and　 [考查连词。根据句意可知,空前的动词remained与空后的动词wrote为并列关系,故此处填并列连词,故填and。]
7.a　 [考查冠词。a large number of意为“许多”,为固定短语,故填a。]
8.economic　 [考查词性转换。此处用所给名词的形容词作定语修饰空后的名词life。economic意思是“经济(上)的;经济学的”,主要用于描述与经济体系、经济活动等有关的事物,符合句意。economical意思是“节约的;节俭的;经济实惠的”,侧重于表示在资源使用、金钱花费等方面节省的意思,故可排除,故填economic。]
9.to see　 [考查非谓语动词。“It is+形容词+to do sth”意为“做某事怎么样”,为固定句型。故填to see。]
10.to　 [考查介词。contribute to意为“有助于”,为固定搭配,故填to。]
