第一节（共15小题；每小题2分，满分30分）
阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项
A
You might not expect it, but cows are a large source of the greenhouse gases that are driving climate change. Cows produce lots of methane by breaking down the grass, Now scientists have shown that the pollution from cows canbe reduced by adding a little seaweed to their food.
Scientists first discovered that seaweed could help control methane from cows several years ago. But this work was done in a laboratory, there were many questions about whether the idea could work in real life.
In the lab studies, the cows were given quite a bit of seaweed, and they would cause losing weight. That wasn't helpful, since cows are often sold by weight. It also wasn't clear if the seaweed would stop working if it was used for a longer period of time.
Now, scientists from the University of California, Davis have answered several of these questions.
The researchers studied 21 cows on a farm for about five months. They taught the cows to get their food from inside a special hood, which allowed the scientists to measure the methane that the cows were giving off. This time, they used a much smaller amount of seaweed, which they mixed with the cows' food.
The results were surprisingly good. In some cases, the cows produced 82% less methane. The improvement depended on the kind of food the cows were given, but even the worst-polluting cows produced 33% less methane.
Over the five months, the scientists didn't see any signs that the cows' stomachs were getting used to the seaweed and starting to produce more methane again.
Another surprise came when they looked at the weight of the cows. The cows that were fed seaweed gained just as much weight as the other cows, but they didn't need as much food.
But there are still some big problems with the idea of feeding cows seaweed. For one thing, there's notadequateseaweed to feed all of the cows in the world. So farmers would have to figure out a way to grow lots of seaweed.
A bigger problem is that for most of their lives, cows live in fields, where they eat the grass. That means there's no chance to feed them seaweed every day. These problems need to be taken seriously if the world is going to avoid the worst effects of the climate crisis.
Still, it's true that something as simple as feeding cows seaweed can help reduce some of the pollution causing the climate crisis.
1. Why did the scientists do the experiment on the farm?
A. To control the amount of seaweed.
B. To record the weight cows gained.
C. To confirm the effect of seaweed in real life.
D. To measure the amount of seaweed cows ale.
2. The underlined word “adequate” means ________ .
A. common
B. special
C. lacking
D. enough
3. The passage is written to ________ .
A. appeal to people not to raise the cows
B. encourage people to plant the seaweed
C. remind people of controlling cows' weight
D. call on people to take actions to reduce the pollution
B
“We are running out of space and the only places to go to are other worlds... Spreading out may be the only thing that saves us from ourselves. I am convinced that humans need to leave Earth.” These are the words of the famous scientist Stephen Hawking, spoken at a science festival inNorwayin 2017, a year before his death.
Hawking was not alone in this view. Many experts feel that the only way for humanity to last far into the future is to colonize other planets. That way, if an asteroid, a terrible disease, nuclear war, or some other disaster strikes Earth, civilization as we know it would still have a chance. Mars is one of the most tempting destinations. NASA, theUnited Arab Emirates, the private company SpaceX, and the organization Mars One all have plans to send humans there. “Either we spread Earth to other planets, or we risk going extinct, SpaceX founder Elon Musk said at a conference in 2013.
But not everyone agrees that colonizing Mars or any other planet is such a great plan. The most common argument against going is that it’s just too expensive or dangerous. It will take huge amounts of money and other resources just to get people there, let alone set up a place for them to live. It’s not even clear if humans could survive on Mars. One of the biggest dangers there is deadly radiation that bombards the planet.
Maybe all the time and money people would pour into a Mars mission would be better spent on more urgent projects here on Earth, like dealing with poverty or climate change. Some experts argue that handling a problem like an asteroid strike or disease outbreak while staying here on Earth would be much easier and less expensive than surviving on a new planet.
In addition, moving to a new planet could harm or destroy anything that already lives there. Mars seems
uninhabited, but it could possibly host microbial life. Human visitors may destroy this life or permanently change or damage the Martian environment. Some feel that’s too much of a risk to take.
What do you think? Should humans colonize outer space or stay home?
4. What can be inferred from the passage?
A. Many experts insist that humans should take the risk.
B. Mars is the most attractive destinations for human beings.
C. Hawking firmly believes the only way to save humans is moving to Mars.
D. All the other experts don’t agree with Hawking’s idea.
5. Why do some experts disagree with the plan to colonize Mars?
A. It will cost much more money to settle on Mars than on Earth.
B. It is too long a distance from the Earth to the Mars.
C. Human visitors will bring diseases to Martian environment.
D. The deadly radiation that bombards the planet is the biggest danger.
6. What’s the writing purpose of the passage?
A. To raise people’s awareness of protecting the environment.
B. To present different opinions on whether to move to the Mars.
C. To arouse readers’ reflection on whether to colonize outer space.
D. To inspire people to deal with the environmental problems.
7. In which section of a magazine is the passage most likely from?
A. Fiction.
B. Current affairs.
C. Social Studies.
D. Science.
C
Disease-carrying mosquitoes can spread diseases without affecting themselves. Nearly 700 million people get a mosquito-borne illness each year, which results in over one million deaths. Humans experience continuous pressures from disease-carrying mosquitoes in many parts of the world, so we have to find ways to fight against those insects because they keep getting scarier.
Even though DEET remains the most commonly used, and most powerful, mosquito repellent ever developed, scientists are actively pursuing effective products based entirely on plant oils. While DEET is an effective contact repellent, many people dislike the oily feel and smell on their skin, and sometimes some people are sensitive to it. Consumers are always interested in alternatives to DEET and other synthetic repellents, so there are numerous natural repellents on the market.
In his lab atIowaStateUniversity, Dr. Joel Coats and his team have successfully tested these repellents against three species of dangerous mosquitoes. The first group of the new repellents act through the air. These chemicals have a vapor action that provides protection, and they are called “spatial” repellents, since they act through space. These are potentially most useful in backyards, parks, and houses. The other group are the classic ones that stop insects from standing on a treated surface, such as human skin, clothing or tents; collaborators at the USDA-ARS and BioGents have conducted testing with humans to confirm the effectiveness and identify the very best ones.
The new repellents were designed and made from the natural materials in plant essential oils. They maintain many of the advantages of the natural repellents: They are fully biodegradable, with no ecological concerns or environmental wastes, and generally considered safe like the thousands of types of plant essential oils used in the flavor and perfume industries. However, thorough testing will be conducted to determine if they are truly non-poisonous because there is still no enough evidence.
8. What does the author mainly want to show in paragraph 1?
A. The way mosquitoes spread disease.
B. The high death rate of mosquito-borne illness.
C. The difficulty of fighting disease-carrying mosquitoes.
D. The urgency of finding tools to fight against mosquitoes.
9. What is a disadvantage of DEET?
A. It won’t be effective for long.
B. It can’t be applied universally.
C. It causes discomfort to the users.
D. It greatly harms people’s health.
10. What can we learn about the second group of the new repellents?
A. They can kill mosquitoes indirectly.
B. They are mainly used in the open air.
C. They are more effective on human skin.
D. They can prevent mosquitoes from contacting users.
11. What’s the author’s attitude to the new repellents?
A. Subjective.
B. Objective.
C. Doubtful.
D. Disapproving.
D
For fishermen and sailors in the seaside town of Shangpan in Linhai, Zhejiang province, where recently 12 stranded（搁浅的）whales were found, it is not unusual to spot whales or dolphins in the sea — they would always
call them haizi, or “son of the ocean”. And if the local fishermen spot such intelligent sea creatures in need, they will save them from danger without hesitation.
In the recent rescue of melon-headed whales, they tried their best to help as a 37-second video of a young man sleeping in the water holding a whale soon went viral online, with netizens applauding his constant efforts and caring heart in trying to keep the whale alive. “The melon-headed whale knew I was trying to save it and would be more cooperative and wouldn’t move.” said Lu Wenhui, a 21-year-old diver from Hangzhou Changqiao Polar Ocean Park, who held up the whale’s head so it could breathe easily. Lu had been staying in the water for 10 hours by 4 a.m. Wednesday after coming for the rescue work on Tuesday, when the stranded whales were first spotted.
“Whales are mammals and need to breathe in air — that’s why I had to hold its head, to ensure it could breathe smoothly the whole time,” Lu said. The stranded whales, after the struggling of being transported, were worn out when they arrived at the fish farm and might have drowned if they were left unattended.
The reason why the whales were stranded is still not clear. And these stranded whales were returned to the ocean because they are not adapted to artificial breeding environments on land.
12. What do local fishermen usually do after finding haizi in danger?
A. Ignore them.
B. Feed them.
C. Transport them.
D. Protect them.
13. Why does the author describe Lu’s rescue work?
A. To introduce the whales in detail.
B. To voice his views on the diver.
C. To praise the efforts made by rescuers.
D. To explain the value of the whales.
14. What can we say about the melon-headed whales according to the text?
A. They are rarely seen by locals.
B. They are used to breathing in the sea.
C. They aren’t suited to artificial surroundings.
D. They are fond of swimming near the seaside.
15. Which of the following can be the best title for the text?
A. Melon-headed Whales Were Stranded
B. Rescuers Went All out to Help Whales
C. Fishermen Transported Stranded Whales
D. Witnesses Voiced Opinions on Rescue Work
