21、It is said that many brain training products is able to keep us mentally fit. Some products even claim that brain training can prevent dementia (痴呆) in old age. Many such products are only money-making rubbish. Also, there is no scientific proof that games or other brain exercises can have this effect. That is what the German Institute for Quality and Efficiency in Health Care (IQWiG) pointed out.
As we get older, our thinking gets slower and it is harder for us to learn new things. Many people try to stay mentally fit by, for example, learning a new language or doing crossword puzzles. Computer games that aim to keep the brain active are also becoming increasingly popular. “Doing exercises like trying to find symbols on a computer screen as fast as possible can actually improve your reaction time,” explains Professor Peter Sawicki, the Institute’s Director. “But scientific studies have shown that brain training only leads to an improvement in one aspect that it is aimed at. So if you learn to find symbols quickly, it does not mean that you will be able to improve your memory.”
Research has not shown that brain training can keep up or enhance (加强) people’s overall (全面的) mental abilities as commonly thought. “So there is no need to feel bad if you do not enjoy brain training: there are no health reasons for doing it,” says Sawicki. “But if you think brain training exercises are interesting, you can try out different things. For example, completing the order of letters can improve your logic skills. And practicing word association techniques can help you to remember things better. You can do all of these things at home on your own.”
【1】What can we learn about the brain training products according to the passage?
A．They are expensive.
B．They are effective.
C．They are harmful to the brain.
D．They are unreliable
【2】According to Peter Sawicki, brain training exercises can________.
A．only improve a certain ability of people
B．help all people improve their memory
C．keep the brain active for a longer time
D．only improve your reaction time
【3】The last paragraph shows that brain training exercises should be done_______.
A．when you can’t learn new things
B．in a relaxing way
C．under strict instructions
D．when your thinking gets much slower
【4】On the whole, researchers think that brain training exercises_______.
A．aren’t as effective as commonly thought
B．are just designed for young people to have fun
C．may benefit people in some indirect ways
D．shouldn’t be encouraged
22、 Solar cars aren't so familiar to us as solar water heaters on top of buildings. However, they're already in races. Solar-powered cars, to be exact, are powered by solar cells that convert (转换) solar energy into electricity. Every few years a collection of strange-looking low black vehicles gather in Australia for the World Solar Challenge, a solar-powered car race covering 3,020 kilometer from Darwin to Adelaide. Various teams from around the world will join in the race, most of which are sponsored (赞助) by universities and companies. The most successful team in the past decade has been a Dutch team from Delft University. Another team, consisting of Hawaiian high school students, was the subject of a famous film, Race the Sun.
The solar-powered cars are allowed to drive through the Outback, the remote and arid areas in the centre of the country in the World Solar Challenge. averaging over 90 km/hr. The purpose of the race is to promote the development of solar-powered cars. This aim has been more than realized, as solar technology has improved so much since the first race in 1987 that the cars can now go well over the legal speed limits. In fact, new rules have been introduced to reduce speeds.
The new aim for solar powered vehicles makers is to develop cars larger and more comfortable than the racing models. In December, Swiss teacher Louis Palmer completed a 17-month, 52,000 km trip around the world in a "solar taxi". His three-wheeled car pulled a trailer with solar cells and batteries. Palmer's solar car can travel 300 km on a single charge, and reach the speed of 90 km/hr. The prototype (原型) was expensive but he hopes that, if mass produced, it would sell for around 10,000 Euros.
【1】According to Paragraph 1, solar-powered cars are .
A.invented in Australia B.used as taxis in daily life
C.powered by electricity D.produced in large numbers
【2】The passage shows the World Solar Challenge .
A.takes place every year B.is sponsored by universities
C.aims to develop solar cars D.features cheap and comfortable cars
【3】What do we know about Louis Palmer?
A.He's the winner of the race this year. B.He's travelled around the world by air.
C.His solar car can travel 300 km per hour. D.His solar car cost more than 10, 000 Euros.
【4】What is the best title for the passage?
A.Solar-powered Cars B.Race the Sun
C.Car Race in Your Dream D.Future Transportation
23、Tiny homes have been popular as home prices have climbed to new heights and people have looked for creative ways to downsize. We’ve seen many design concepts, including storage units and buses, but Jim Dotzenrod and his daughter Danielle recently came up with a unique one. The pair worked together on the family project to transform a 1973 train caboose into the sleeper car.
The CR Station Train Caboose, as it’s known on Airbnb, which has become somewhat of its own tourist destination in the small town that houses it, is available to rent for $124 a night, and has an excellent rating of 4.86 out of 5 from more than 300 guests on the booking website.
According to Insider, the project began when Jim saw a bunch of train cabooses along the side of the road during a drive out of town. He said he wondered if he could change one of them into a place where people could live or stay. So, he bought the 52,000-pound caboose for $8,000. Getting the caboose to its final home took some creative thinking and some heavy-duty equipment.
Danielle said the work was challenging, especially since she and her dad both have day jobs. But their schedules didn’t stop them from finishing the project. “My dad can do anything he sets his mind to — like, absolutely anything — but my dad is so low maintenance himself,” Danielle told the website. “So when we built this together it was a good combination because he could build whatever and have me pushing him like, ‘Hey, let’s make this as cool as we can.’”
This caboose also has Wi-Fi, air-conditioning, a refrigerator, a shower and more. So, if you’re ever traveling in Iowa and want to experience something special, book a stay at the CR Station Train Caboose!
【1】What can we know about the CR Station Train Caboose?
A．It can only be booked online.

【2】The words “low maintenance” in paragraph 4 indicate Jim Dotzenrod is ________.
A．easy and pleasant to deal with
B．determined to do what he wants
C．excellent at building houses
D．experienced in project design
【3】What is the purpose of the last paragraph?
A．To introduce a lifestyle.
B．To share an experience.
C．To show a travel trend.
D．To make an advertisement.
24、 Gray wolves will no longer be protected under the Endangered Species Act in most of the US, federal officials announced this week.
“After more than 45 years as a listed species, the gray wolf has reached all conservation goals for recovery,” Interior Secretary David Bernhardt said.
This move was criticized by wildlife advocacy groups and environmentalists who decided to challenge the decision.
“Abolishing protections for gray wolves is irresponsible,” said Defenders of Wildlife President and CEO, Jamie Rappaport Clark. “Gray wolves occupy only a small part of their former range and need continued federal protection to fully recover. We will be taking the US Fish and Wildlife Service to court to defend this species.”
The new rule will officially publish next week, and go into effect 60 days after that. Then, states will assume control of gray wolves and accept for Mexican wolves, a subspecies that will remain protected under the Endangered Species Act.
Over the years, there has been a back-and-forth between conservation groups and the Fish and Wildlife Service over whether the gray wolf should be delisted (除名) as an endangered species. The last attempt was under the Obama administration, but was met with fierce opposition and was later withdrawn.
There was also a lot of opposition to the recent delisting of the gray wolf, with more than 837,000 comments noted online. According to the Humane Society of the United States (HSUS), the organization submitted more than 1. 8 million comments opposing the rule.
While the federal government is removing protections, at least one state is hoping to add them. There is currently a question on the vote in Colorado about a gray wolf recovery program, which would reintroduce the animal in the state. The proposal would reintroduce and manage gray wolves by the end of 2023.
"Wolves remain absent from about 70% of currently suitable habitat in the lower 48 states, and this rule could have terrible consequences for their future,” Amanda Wight, Program Manager of Wildlife Protection said.
【1】How does Bernhardt feel about the gray wolf recovery?
A．Urgent.
B．Worrying.
C．Successful.
D．Impossible.
【2】What will environmentalists do to defend gray wolves?
A．Set more protection rules.
B．Call on environmentalists to donate.
C．Ask the government to set up more reserves.
D．Accuse the US Fish and Wildlife Service.
【3】What can we know about the delisting of the gray wolf?
A．The related rule has been in effect.
B．It has been under debate for years.
C．Many people vote to support it.
D．Colorado will be the first to carry it out.
【4】What can be the best title for the text?
A．The Endangered Species Act is going into effect
B．The number of gray wolves is largely increasing
C．Gray wolves will lose Endangered Species Act protection
D．The Endangered Species Act will meet great change
