Dion was having a running race. This race would stretch in six stages over seven days and cover almost 155 miles. Gobi, a little she-dog happened to join him. It was their third day.
The sky was clear, the weather was warm: the ground was firm beneath Gobi’s feet. From time to time, Dion would look over at her and smile. The warmth of that smile was even brighter than the sun beating down on them, but in a good way. It filled Gobi up.
As they progressed, a broad river popped into their sight, lying right in front. Dion had no idea how deep it was, but the race markers led right across, so he had to assume he’d be able to make it across as well.
Taking a deep breath, he took a careful step into the water. It was surprisingly cold considering how warm the day was, and he sank down up to his waist, but that was it. At least the riverbed seemed solid. He could make his way across; he just had to go slowly. One wrong step and he’d get completely wet. Plus, he could hurt himself since he couldn’t see where he was putting his feet. This was going to take a while.
Gobi watched as the man jumped into the water. She wagged her tail, but he didn’t look her way. He was clearly busy concentrating. She sat down just before the water and watched. Surely, he would turn around and notice that she wasn’t with him. But several minutes passed, and he got farther and farther away. Finally, Gobi couldn’t take it any longer. She began anxiously running up and down the riverbank. Was the man going to leave her?
At the sound of her bark, Dion stopped. He always made a point of facing forward, always forward, during a race. But this time he did glance back. Gobi was sitting at the river’s edge, barking fiercely. There was no way the little dog could cross that on her own. These days, he’d fed her, given her water, and named her. He had to admit that he liked having her with him. She lifted his spirits.

5 . For those of us who grew up watching Star Trek, exploring space has been about discovering strange new worlds. And there are plenty of worlds to explore in time, but we still need major technological advancements to reach planets that are light years away.
What we are doing in space today is providing unbelievable benefits right now, right here on Earth. From space, we can monitor, manage and care for our planet. Satellite-based sensors show us the short- and long-term effects of human activity on our environment. Many companies are using their interest in space to help solve problems here, from using hyperspectral imaging(高光谱成像), which enable us to map vegetation(植被) and rain forests, to microsatellites that provide global connectivity for the network of things.
My company, OneWeb, is focusing on what I believe is one of the world’s most important issues: the need for equal access to the Internet. The Internet has become our economic lifeblood. And yet, nearly half of the world’s population doesn’t have Internet access. Space is playing a key role in bridging this digital divide. OneWeb is launching 1,980 satellites to help bring Internet access to people everywhere, and our first production satellites are already flying in space and have shown very high download speeds.
Fiber and cable Internet access technologies already cover most financially viable(可行的) major cities. Similarly, these regions will also be the first to be served with 5G. Poor communities are the last to get connected, and without connectivity, those communities have no chance to lift themselves from poverty. OneWeb’s satellites will reach every community in the world and enable equal access to the Internet for the world’s less developed places.
Fifty years from the day when man first walked on the moon, we are still only approaching the possible. There will be tens of thousands of new satellites, space stations and factories in the coming years to bring advancements in communications, scientific research, monitoring the earth, exploring space and more. This is exciting, but we must take action carefully.

6 . The cotton harvest is about to get underway in the Texas High Plains, the windswept region that grows most of the crop in the nation’s top cotton-producing state. But Barry Evans, a third-generation cotton grower, has already walked away from more than 2,000 acres (英亩) of his bone-dry fields. “It just didn’t come up. We hardly had anything,” said Evans.
Extreme heat and a lack of rainfall have severely damaged much of this year’s cotton harvest in the U.S., which produces about 35% of the world’s crop. The U.S. Department of Agriculture (USDA) forecast that more than 40% of what U.S. farmers planted in the spring would be abandoned because of drought. Nowhere is this more apparent than the flat, dry stretch of Texas. The USDA says Texas cotton farmers are likely to abandon nearly 70% of their spring planting. That has been the worst harvest since 2009.
The region normally receives around 18 to 20 inches of rain per year, but saw less than three inches of rain from August through the summer, as nearly all of Texas baked under drought. Much of the cotton grown in the region needs rain. Even those with irrigated (灌溉的) fields are expecting low yields (产量) this year.
The losses in cotton could cost the Texas High Plains $1.2 billion after farmers receive federal (联邦的) crop insurance payments, estimates Darren Hudson, director of the International Center for Agricultural Competitiveness at Texas Tech University. That leaves out others who depend on the crop, such as cotton gins (轧棉机) and storehouses. “Any time you have a bad year in cotton, it has a role to play in the overall economy,” Hudson said.
Fortunately, most cotton farmers in this part of Texas plan to use cotton seed varieties that can resist drought. Varieties are continuously developed and will be adjusted to generate high yields if dry conditions continue. “Even though it’s drought resistant,” Hudson added, “we still have to have a little bit of help from Mother Nature.”

7 . Vast lands of America are dominated by corn, nearly 100macres of it, stretching from Ohio to the Dakotas. What once was forest today produces the corn that feeds people, cattle and, when made into ethanol (乙醇), cars.
Now, the nation’s airlines want to power their planes with corn, too. United Airlines signed a deal with a Nebraska ethanol company to buy enough sustainable fuel, to power 50,000 flights a year. The government could decide on its tax incentives (税收激励) for the industry as soon as December. “Mark my words, the next 20 years, corn farmers are going to provide 95% of all the sustainable airline fuel,” President Biden said in July.
The airlines’ ambitious goal would likely require nearly doubling ethanol production, which airlines say, with great expectation, would decrease their greenhouse gas emissions. If they succeed, it could transform America’s Corn Belt, stimulating farmers and ethanol producers, but potentially further damaging one of the nation’s most important resources: groundwater.
Corn requires a lot of water to grow and it can take hundreds of gallons to produce a single gallon of ethanol. But as airlines take the idea of ethanol, the vital groundwater faces serious risks. “We’re on track to massively increase water usage without any real sense of how sensitive our groundwater is,” said Jeffrey Broberg, who is concerned about groundwater in Minnesota, a major corn state.
The Department of Energy said in a statement that “water use is a critical part of the conversation surrounding bio-energy sustainability”. It pointed to a 2022 department study that concluded that the United States could significantly reduce pressure on groundwater by shifting fuel production away from water-intensive crops like corn, instead growing more crops that don’t require irrigation (灌溉), like various types of straw, grasses and trees. Hopefully, a better approach will be soon studied and adopted.

9 . Tropical (热带的) forests could become so hot that some kinds of leaves will no longer be able to conduct photosynthesis (光 合 作用), according to a study. The photosynthetic machinery in tropical trees begins to fail at about 46.7℃ on average. The research suggests that forests may be nearing dangerous temperature sooner than expected. Models predict that once we hit a global temperature increase of 3.9℃, these forests might experience mass leaf damage.
Chris Doughty, an associate professor at Northern Arizona University and the lead researcher of the study, said the leaf-warming experiments had revealed a nonlinear rise in temperatures. “We were really surprised that when we warmed leaves by 2, 3 or 4℃, the highest leaf temperatures actually increased by 8℃. This shows a concerning nonlinear feedback that we were not expecting.” said Doughty. “If we adopt a do-nothing response to climate change and tropical forest air temperatures increase by greater than 4℃, there could be massive leaf death.” he added.
Avoiding high emissions (排放) in the first place is key to stabilizing temperatures. “We should do all we can to avoid high-emissions. Under low-emissions, almost all tropical forest tree leaves can avoid death from overheating and the trees will survive,” said Simon Lewis, a professor of global change science at University College London. “Yet what the study doesn’t look at is heatwaves. We still might see tree deaths from overheating for limited periods during heatwaves under lower emissions.”
Researchers suggest that the damage is not yet unchanged. “Vote for people who are serious about addressing climate change and transferring to low-carbon economies, ”Disney, one researcher, advocated. More generally, we can all recognize the importance of supporting those countries and people who live in and rely on tropical forests economically, But the serious changes to tropical forests don’t just affect the local people it’s a global issue.
1. Which of the following can best replace the underlined word “nonlinear” in Paragraph 2?A.Global. | B.Dramatic. | C.Steady. | D.Minor. |

10 . Can you name a famous elephant? Babar, perhaps? Or Dumbo? Though these names may be memorable to humans, they sound nothing like the names elephants give each other. “If you’re an elephant, your name is something more like a low, rumbling sound (隆隆的声音),” scientists say. Researchers have found that African elephants emit sounds in response to individuals in their social group, and the receivers respond accordingly.
Researchers recorded 527 elephant calls in northern Kenya and 98 calls in southern Kenya. They then distinguished which members were separated from the herd at the time of each call, or which members were close to the herd. Researchers correctly identified the receivers of 20.3% of the 625 recorded calls. This marks a step forward in understanding how these highly intelligent animals communicate.
“There’s a contact rumble, an anti-predator rumble and a greeting rumble. If you look at a spectrogram (声谱图) with your eyes, they all look almost exactly the same,” said Caitlin O’Connell-Rodwell, an elephant biologist at Harvard Medical School. “That’s why artificial intelligence(AI)has been exciting. It allows us to really figure out what the elephants are saying.”
As it turned out, the calls were distinct to the receivers. Even calls from different callers to the same receiver were similar. The pattern was less obvious than it was between a single caller and his or her receiver. This may be because rumbles encode multiple messages at the same time, so the AI system in computer model may not have been able to pick out the “name” used in each call. “It just highlights the complexity of what’s going on. And we’re not skilled enough in these measurements to figure out what’s going on,” said Caitlin.
However, the research shows how elephants are navigating through a large landscape and can still keep in touch with specific individuals. It allows them to spread out much further and still have very close tabs on individuals, not just the group.
