1、2022届辽宁省普通高中高三模拟试卷(一)英语试题学校:_姓名:_班级:_考号:_一、阅读理解The Surprising Benefits of Taking a Cold ShowerYoull procrastinate (拖延) less.Putting things off is a habit everyone would love to lose. No one wants to take a cold shower, but the more routinely you bite the bullet and get it over with, the more youre t
2、raining your body not to get hung up on those moments of hesitation. As time goes on, this habit will extend to other areas of life.Youll be more resistant to stress and depression.Brief changes in body temperature like a cold shower have been theorized to help brain function and activate beta-endor
3、phin (B-内啡肽) and noradrenaline (去甲肾上腺素) in the brain. Beta-endorphins are “feel-good” molecules that give a sense of well-being. Noradrenaline is an adrenal hormone (肾上腺激素) that helps depressed people feel more “up” naturally. Cold water bathing, meanwhile, also reduces the cortisol hormone (皮质醇激素),
4、 which usually kicks into action when stress and anxiety take over.Youll get sick far less.Cold showers lead to higher numbers of white blood cells circulating throughout your body, which is never a bad thing. Those helpful little cells work hard to protect you from disease and illness.Your skin and
5、 hair will glow.Cold water tightens your skin that gives a natural glow to the skin. When it comes to your hair, cold showers close and fortify your hair cuticles while adding more strength to them. Moreover, cold water also doesnt harm the natural barrier of your skin and hair.1Which of the followi

7、m for rail operators.When leaves fall on to a railway line, they form an extremely low-friction black paste. When compressed by a slowly moving train, the paste becomes sticky and prevents the wheel from touching the rail, leading to lengthy delays and extreme safety concerns.Discovering why leaves
8、pose such a problem has taken years of research.Sycamore (梧桐树) leaves are known to create this slippery black substance. It reduces friction between wheel and rail to around 0.01 per cent the same as between ice and a skate.To find out what chemical in the leaves was responsible for the paste, the r
9、esearchers used a process of elimination (排除过程). Different chemicals were removed but the paste still formed. However, when tannins (单宁酸) were removed, the paste did not form.In plants, these large molecules are used to soak up disease and stop it spreading, as well as making the plants taste bitter
10、 in order to discourage animals from eating them. But when the leaves fall on to a railway line, these tannins react with charged iron particles from the steel rails to form an extremely low-friction black paste.“With this chemical reaction found and linked to low friction phenomena, interventions (
11、干预措施) can be designed,” researchers conclude. They say this discovery could help design policies to cut down problem trees. For example, instead of removing all trees near railway lines, it may be better to just cut down the species that contain tannins.However, another solution may lie in stopping
12、the tannins from the leaves interacting with the ions (离子) in the steel at all. “Interventions can be designed to target the specific reactions or chemicals,” the researchers say. At present they are still working on it.4Whats the problem with leaves on the line?AThey do harm to the environment.BIt
13、s hard for rail operators to clean up them.CWhen pressed their chemical slows down the train.DThey increase the friction between the train and railway.5What does the underlined phrase “soak up” probably mean in Paragraph 6?Acause.Babsorb.Creduce.Dincrease.6Whats the proper solution according to rese
14、archers?ARemove tannins from leaves.BGet rid of all trees near railway lines.CChange the position of railway lines to avoid leaves.DPrevent the chemical reactions between tannins and ions.7What can you infer from this text?AThe troublesome leaves will cause danger to passengers.BThe discovery of the
15、 chemical reaction helps design policies.CTannins are responsible for the paste formed by compression.DCurrently, researchers succeed in stopping the chemical reaction.The worlds first 3D-printed steel footbridge, measuring 12 meters in length, has been installed in Amsterdam. The bridge, created by
16、 a Dutch company called MX3D, has been installed over the Oudezijds Achterburgwal canal.More than four years in the making, the S-shaped bridge will act as a “living laboratory” in the Dutch capital as it handles pedestrian traffic.Researchers at Imperial College London are assessing the “performanc
17、e” of the bridge, which is packed with sensors, as its being walked on.Data collected from the sensors will enable experts to monitor how it changes over its lifespan, such as if the steel yields (变形;弯曲) due to football, and measure how the public interacts with the bridge, such as how many people a
18、re using it.“A 3D-printed metal structure large and strong enough to handle pedestrian traffic has never been constructed before,” said Leroy Gardner of the Department of Civil and Environmental Engineering. “We have tested and stimulated the structure and its components throughout the printing proc

Performance of the physical bridge will be tested against the twin, which will hel
20、p answer questions about the adequacy (妥善性) of 3D- printed steel and inform future construction projects. According to MX3D, the bridge is more than just a functional object for the public, but an art, installation and a celebration of technology.“3D printing presents tremendous opportunities to the
21、 construction industry, enabling far greater freedom in terms of material properties and shapes,” said Gardener. “This freedom also brings a range of challenges and will require structural engineers to think in new ways.”8What makes the bridge special?AThe S-shape.BThe metal structure.CThe 3D-printi
