26、Satellites are already in use for so many purposes today — from weather forecasting to communications, GPS, and more. Since the late 1970s, satellites have also been used to monitor changes in the Arctic sea ice. Data suggests that sea ice is thinning over time due to climate change. Over the last forty years, the extent of Arctic ice cover has been declining at a rate of 13%per decade. However, existing ways of measurement do not provide a clear and continuous picture of the state of sea ice.
This September, scientists developed a new method that combines computer modeling and satellite data to predict ice thickness all year round. Over the years, scientists have proposed several methods to measure ice thickness. These include flying planes over the Arctic Ocean or collecting field measurements.
Neither of these methods provides a full picture of Arctic melt, making year-long data collection difficult. Continuous data across the entire region from satellites is a great way for scientists to understand how climate change is playing out in the Arctic.
These satellites use special radar or laser-based altimeter instruments. Sea ice thickness is then calculated as the difference between the height of the ice and the top of the water(ice level — sea level). This method works well during the winter months — September to May.
Unfortunately, satellite-based sea ice thickness measurements are inaccurate during the summer months: the time of the year with the greatest melting. This melting creates a pool of liquid water on the surface. As a result, the simple calculation (ice level — sea level) does not work as radar systems are unable to differentiate between ocean water and ice, thus rendering measurements inaccurate.
New research led by Jack Landy, a scientist, seeks to tackle this age-old issue. The team used machine learning and deep learning methods to distinguish between seawater and ice.
The researchers built a model of the radar system’s predicted data and cross-referenced these values to those collected by a satellite. This model allows the researchers to obtain accurate, year-round Arctic sea ice thickness data.
【1】Why are satellite-based sea ice thickness measurements not accurate?
A．The ice melts in summer months
B．The radar system doesn’t work in winter.
C．The liquid water turns ice in cold days
D．The ocean water comes onto the ice surface.
【2】What does the age-old issue refer to?
A．The changeable climate change
B．The incorrect ice measurements.
C．The constantly flowing ocean water.
D．The great amount of melting ice.
【3】How do the researchers study Arctic sea ice changes in the new research?
A．By using satellites to collect data.
B．By collecting field measurements
C．By flying planes over the Arctic Ocean.
D．By using machine learning and deep learning methods.
【4】What is the best title for the passage?

27、Today we know Antarctica as an extreme environment containing ice and snow. But new research provides evidence that the area had a rainforest in the past.
The researchers collected a piece of Earth sediment (沉积物) from under the seafloor off the coast of Antarctica. In the sediment, they discovered forest material that was estimated to be about 90 million years old. This would have been in the Cretaceous Period, when dinosaurs were the main land animals. The sediment was removed by scientists on the research icebreaker RV Polarstern in the Amundsen Sea near Pine Island Glacier.
Johann Klages is a geologist with the Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research in Germany. He was the lead writer of a study on the findings, published in the journal Nature. He said the sediment was collected from a depth of about 30 meters below the ocean floor. Klages said an examination showed that the material didn’t form in the ocean.
The researchers estimate that the area — about 900 kilometers from the South Pole — had average yearly temperatures of about 12 to 13 degrees Celsius. During the warmest summer months, average temperatures likely reached between 20 and 25 degrees Celsius. The soil included fine dirt particles (颗粒) and hard clay (粘土), as well as substances linked to at least 65 different kinds of plants, the study found. Klages added that the plants included trees, ferns (蕨类) and flowering plants. While no animal remains were found, Klages said there were likely dinosaurs, flying reptiles and many insects in the environment.
The research represents new evidence of the major climate changes that Earth has experienced in the past—and is currently undergoing today. The soil in the sediment dates back to the planet’s warmest period of the past 140 million years, with sea level about 170 meters higher than today. The researchers said that the rainforest environment in Antarctica was especially surprising because each year, the area experiences a four-month polar night when there is no sunlight to fuel plant life. Klages said no ice sheets were present during the time, but seasonal snowfall was likely.

28、A bicycle may be seen by most people as just another vehicle(交通工具), but for many Londoners, cycling is a way of life. According to a UK government survey in 2020, about 570,000 bike journeys were made every day in London. In fact, almost half of the vehicles that pass over London Bridge each day are bikes.
London introduced a public bike-sharing system in 2010. “There can be no doubt that our trusty bicycles have changed that way people get around our great city,” Johnson told The Guardian.
In London, bikes are used for more than just taking short trips to and from the subway. NO matter where you want to go in the city, riding a bike is usually the quickest and easiest choice.
And it’s not just shared bikes that the government is encouraging people to ride. In many companies across the UK, the UK government’s Cycle to Work scheme(计划) allows workers to buy a brand new bike without having to pay any tax (税). This means that it’s common to see many people cycling to and from work, and some employers even provide showers and lockers in the workplaces for their workers. More importantly, a cycle-friendly boss may let you off for being late if you ride a bike to work.
Not only is it great for the environment and our body, cycling is also good for the mind. According to National Geographic, “Bike riding can improve people’s happiness.”
【1】How does the author show the popularity of cycling in London?
A．By using numbers.
B．By giving examples.
C．By making comparisons.
D．By using famous sayings.
【2】What’s Johnson’s attitude towards the bike-sharing system in London?
A．Disappointed.
B．Concerned.
C．Supportive.
D．Uninterested.
【3】What can workers get from the government under the Cycle to Work scheme?
A．Free bike-sharing services.
B．Showers and lockers in workplaces.
C．Shorter working hours.
D．Tax-free bikes.
【4】Which of the following can be the best title of the passage?
A．Cycling, a healthy way of life.
B．How cycling has become popular in London.
C．Why Londoners are encouraged to ride bikes.
D．London’s public bike-sharing system.
29、 With unfamiliar environments, a heavier workload (工作量), and social challenges, the change from primary school to high school is difficult.
When 800 new high schoolers graded their feelings of worry on a scale (量表) of one to ten, one quarter said seven or more, suggesting serious stress (压力). Disturbingly, these uneasy youth were the most likely to cut classes, start smoking or even get involved in (卷入) self-harm, according to McGill University researcher Dr. Nancy Heath, who has studied the students for three years.
Luckily, there’s a good cure for your high schooler’s worries — volunteering. Parents are already struggling with over-scheduled kids, but the mental-health benefits of this particular after-school activity are widely recognized. “There’s clear evidence (证据) that doing something for others can help people manage stress,” Heath says. The biggest benefit is making new friends. High school is a social minefield (雷区). Teens struggling to find new friends can feel lonely.
They need a back-up social scene outside the classroom, Heath suggests. “Volunteering and getting involved gives a sense of community and belonging.” Team sports and some hobbies are social, but they can’t match the other benefits of volunteering. Serving food in a soup kitchen or chatting with lonely old people forces a teenager to focus on the needs of others, instead of thinking about their own worries.
We’ve found that, among youth who volunteer through our service programs, 61 percent report feeling increased self-respect. They’re 1.3 times more likely to have a strong sense of self than their peers (同龄人), and are more comfortable adapting to (适应) changes, according to an independent study by research firm Mission Measurement.
This winter, encourage the new high school student in your house to find a cause they’re interested in and get involved. It won’t help them find their locker, but it will ease the stress.
【1】What would anxious high schoolers probably do according to Heath?
A．Disturb their schoolmates.
B．Damage the environment.
C．Stay away from school.
D．Harm other students.
【2】Why does the author encourage kids to volunteer?
A．It may reduce their mental pressure.
B．It may be good for their physical health.
C．It may help improve their learning skills.
D．It may free them from their busy schedules.
【3】What can we learn about youth volunteers form Mission Measurement’s study?
A．They are glad to help their peers.
B．They begin to respect other people.
C．They are able to fit in with the new conditions.
D．They know more about their problems than peers.
【4】For whom is the text mainly written?
A．Researchers.
B．Teachers.
C．Students.
D．Parents.

31、A patent is an official document 【1】(give)to an inventor by a government. This document 【2】(general) gives inventors the right to stop anyone else from copying, using or selling the invention without their permission.
Inventions are the result of hard work. It may only take a moment of inspiration to think of a good idea but it takes a lot of research and experimentation to turn it into a(n) 【3】(use)and working invention. So, inventors deserve a reward for the amount of time they spend 【4】(develop)their ideas. They also need the 【5】(secure) of knowing that if they share the invention with 【6】rest of the world, nobody will steal it, use it or copy it without their permission.
Patents also benefit the society 【7】 return for patent protection. Inventors agree 【8】(show)all the technical information about their invention. This information is available to everyone and has enough details 【9】can be used by people with basic knowledge to produce the invention. In this way, patents help to spread new knowledge, which can in turn help people find 【10】(solve)to different problems or to make further advances in science and technology.
