21、Deep within the Yukon, one of the most densely wooded areas of Canada, sits a patch of land that is unlike any other forest on the planet. Instead of a canopy of treetops spreading across the horizon, tens of thousands of signposts perch haphazardly one on top of the other. They are all part of the Signpost Forest, the largest collection of signs from places around the world. At last count, the Signpost Forest in Watson Lake, located about 10 miles north of the U.S.-Canadian border, contains 91,000 signs from spots near and far.
The tradition began during the Alaska Highway Project in 1942, when U.S. soldier Carl K. Lindley spent time in Watson Lake recovering from an injury. A commanding officer asked him to repair and erect the directional signposts, and while completing the job, the homesick soldier added a sign that indicated the direction and mileage to his hometown: “Danville, Illinois, 2,835 miles.” Others followed suit, and the trend caught on. Each year, an average of 1,000 new signs are being added to the collection. Lindley’s original sign has since been lost to time. Fifty years later, in 1992, Lindley and his wife Elinor made the pilgrimage back to Watson Lake to place a replica, which is still there.
The Signpost Forest takes up a couple of acres, with huge panels snaking through the trees. There are street signs, welcome signs, signatures on dinner plates, and license plates from around the world. There are also a lot of familial signs; for example, a grandfather will put up a sign and then years later family will come back and try to find it. A lot of these are personal signs to literally say that they are here. Though the visitor center has wood and paints on hand to help create a sign, many people opt to bring their own signs, though illegally, by snatching a metal sign from their hometown and nailing it to one of the wood posts. The forest has grown so vast that the visitor center no longer tries to keep a detailed list of the signs.
【1】What does “The tradition” in the second paragraph refer to?
A.Counting the number of signs in the Signpost Forest.
B.Replacing the natural forest with signs of different kinds.
C.Putting directional signposts on the highways of the Yukon.
D.Bringing signs to the Signpost Forest from around the world.
【2】According to the passage, which of the following is true about the first sign in the Signpost Forest?
A.It remained in the Forest until 1992.
B.It was erected by an American soldier.
C.It was first put on the Alaska Highway.
D.It was brought from Lindley’s hometown.
【3】Which of the following is closest in meaning to the word “replica” in the second paragraph?
A.List.
B.Trunk.
C.Copy.
D.Border.
【4】What is the last paragraph mainly about?
A.The origins and sizes of the signs in the Signpost Forest.
B.The quantity and variety of the signs in the Signpost Forest.
C.The difficulty of categorizing the signs in the Signpost Forest.
D.The practice of nailing illegal signs to the posts in the Signpost Forest.
22、Crossing your legs is an extremely common habit; most people don’t even notice that they’re doing it when they sit down. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.
A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason this happens is because the blood in your legs has to work against gravity to be pumped back to your heart, crossing one leg over the other increases resistance, making it even harder for the blood to circulate. This causes your body to increase your blood pressure to push the blood back to the heart.
Crossing your legs can also lead to neck and back pain. When you sit with your legs crossed, your hips are in a twisted position, which can cause one of your pelvic (骨盆的) bones to rotate. Since your pelvic bone supports your neck and spine, this can cause pressure on your lower and middle back and neck.
You also might notice that when you sit with your legs crossed for long periods of time, your feet and legs get tingly or have the feeling of being asleep. This is because when one leg sits on top of the other, it causes pressure on the veins (血管) and nerves in your legs and feet. It can cause numbness and/or temporary paralysis in the legs, ankles, or feet.
So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.
【1】Crossing legs may lead to the following health problems except ________.
A. It can increase your blood pressure
B. It can cause pressure on your lower and middle back and neck
C. It will make your neck and spine twisted
D. It can cause paralysis for the time being
【2】Why can crossing your legs increase your blood pressure?
A. Because the blood in your legs has to work against being pumped back to your heart.
B. Because it will prevent the blood circulating.
C. Because crossing legs results in less resistance for the blood to circulate.
D. Because higher blood pressure contributes to pushing the blood back to the heart.
【3】What is the purpose of writing this article?
A. To persuade us not to cross our legs any longer.
B. To make us aware of the health problems caused by crossing legs.
C. To tell us the benefits of sitting with our feet on the floor.
D. To show that crossing legs is an extremely common habit.
23、
E-cigarettes一thought by some to be responsible for a decline in youth cigarette smoking---are actually attracting a new population of adolescents who might not otherwise have smoked tobacco products, according to anew UC San Francisco study.
In the first national analysis of the impact of e-cigarettes on trends in youth smoking in the United States, UCSF researchers did not find evidence that e-cigarettes have caused youth smoking to decline. In fact, combined e-cigarette and cigarette use among adolescents in 2014 was higher than total cigarette use in 2009,according to the study.
The authors concluded that the low-risk youth in the study, who went on to smoke regular cigarettes, may not have used nicotine at all if e-cigarettes did not exist.
“We didn't find any evidence that e-cigarettes are causing youth smoking to decline, ”said lead author Lauren Dutra, a former postdoctoral fellow at the UCSF Center for Tobacco Control Research and Education and current social scientist at RTI International, a not-for-profit research organization based in North Carolina.
“While some of the kids using e-cigarettes were also smoking cigarettes, we found that kids who were at low risk of starting nicotine with cigarettes were using e-cigarettes," Dutra said. “Recent declines in youth smoking are likely due to tobacco control efforts, not to e-cigarettes.”
The national analysis builds on several previous studies that have reported that adolescents who start withe-cigarettes are more likely to subsequently smoke traditional cigarettes.
In August 2016, the US Food and Drug Adminis-tration restricted e-cigarette purchases to adults ages 18and older( California set the age to 21). The FDA also will require a warning label on e-cigarettes, starting August2018, regarding the addictive nature of nicotine. However, the FDA's ruling does not regulate advertising or flavors,and e-cigarettes continue to be sold in flavors that appeal to youth.
【1】What is the initial purpose for e-cigarettes to be invented?
A.To warn people of the harm of smoking. B.To discourage people from smoking.
C.To make cigarette smoking less harmful. D.To help kids give up smoking.
【2】What do we learn about e-cigarettes, according to the study?
A.They actually have a negative influence on youth.
B.They are helpful in keeping kids away from smoking.
C.They help reduce the number of smokers.
D.They turned out to be less harmful than cigarettes.
【3】What probably caused the decline in youth smoking?
A.People's awareness of health. B.The use of e-cigarettes.
C.Efforts to control tobacco. D.Restrictions on e-cigarette sales.
【4】What's the suggestions of the FDA?
A.Advertising for e-cigarettes should be stopped.
B.There should be a warning label on e-cigarettes.
C.E-cigarettes should not contain flavors.
D.E-cigarettes should be further promoted.
24、Extreme heat often brings extreme wildfires, and this year is no exception, with heat waves fueling giant outbreaks of fires in the western United States and Canada, as well as across the Mediterranean and in Siberia. However, the wildfires can have the opposite effect on temperatures, cooling Earth's surface regionally and globally.
Thick wildfire smoke can temporarily block sunlight near the ground, causing regional temperatures to drop by several degrees. Wildfire smoke can also have global cooling effects by making clouds in the lower atmosphere more reflective or blocking sunlight in the upper atmosphere, similar to what a volcanic eruption does.
Scientists have only recently begun studying these effects, with Australia's record 2019-2020 bushfire season marking the first time researchers detected wildfire smoke-caused global cooling. The effect is far too small to balance human-caused global warming, but beyond that, researchers say it's too early to predict what it means for the broader climate system. But with fire seasons growing severer around the world and this summer witnessing much extreme fire weather in North America and elsewhere, the search for answers is growing increasingly urgent.
Scientists at the National Center for Atmospheric Research reported that those Australian fires poured so much smoke into the Southern Hemisphere's atmosphere which caused a “strong and rapid” global cooling effect of about 0.06℃ (0.01°F). According to the lead study author John Fasullo, this was largely due to how smoke particles interact with clouds in the lower atmosphere.
While Fasullo's research highlights the cooling effects of smoke in the lower atmosphere, on occasion, wildfire smoke rushes into the higher atmosphere. There, it can have additional effects on the climate, which is something that is poorly known. “We might still be in the initial stage of understanding how large and how important the effects of these wildfires are,” says Sergey Khaykin, a fire weather expert at Sorbonne University in France.
【1】What does the second paragraph mainly talk about?
A.Wildfire breaks out more often now.
B.Wildfire smoke cools Earth's surface.
C.Regional temperatures increase due to wildfire.
D.Volcanic eruption affects the upper atmosphere.
【2】What can we infer about the effects mentioned in paragraph 3?
A.They are too small to be noticed.
B.They can be accurately predicted
C.They deserve an in-depth study.
D.They can improve the global climate.
【3】How does the author prove the global cooling effect in paragraph 4?
A.By giving an example.
B.By listing figures.
C.By making comparisons.
D.By doing an experiment.
【4】What message does the author want to convey in the last paragraph?
A.Climate change is in need of a global solution.
B.The higher wildfire smoke rushes, the cooler it gets.
C.Weather experts are satisfied with Fasullo's research.
D.The influence of wildfires needs to be explored further.
