The cold, wet weather of winter often puts out any wildfires that are still burning, but not in the far North areas, such as Alaska, Canada, and other parts of North America. Some forest fires just don’t die in these places. Think of the fires as “zombies” (僵尸): Scientists do. When summers are warmer than normal, some fires can hide through the winter. They burn dead plant matter and soils under snow. In May 2021, scientists reported their work to a scientific journal. The scientists saw that zombie fires are rare but they could become more common as the world warms, the study warns.

“Some years, new fires were starting very close to the previous year’s fire,” explains Rebecca Scholten. She studies Earth and environmental sciences at Vrije University Amsterdam in the Netherlands. The new fires made scientists wonder how often fires might survive the winter. The scientists started by combing through firefighter reports. Then they compared these with satellite images of Alaska and northern Canada. The scientists looked for fires that began close to fires from the year before. They also focused on blazes starting before the middle of summer. Random lightning or human actions spark most fires in the area, Scholten says. But those fires happen later in the year.

Zombie fires accounted for less than 1 percent of the total area burned by fires from 2002 to 2018. But it changed from year to year. Take 2008, for example. A zombie fire burned Alaska that year. It caused almost one-third of fire damage that year. One clear pattern emerged: Zombie fires were more likely to happen after very warm summers. High temperatures may allow fires to reach more deeply into the soil. Such deep burns are more likely to survive to spring.

The zombie fire threat could grow. The climate is warming. Forests in the far North already are warming faster. “We’re seeing more hot summers and more large fires and intense burning,” Scholten says. Plus, zombie fires could cause more issues. The fires release huge amounts of greenhouse gases. These trap heat in the Earth’s atmosphere. The atmosphere is a layer of gases that surround the Earth. Scholten’s research could help fire management. Firefighters would know to check for them after warm summers.

1. What may lead to zombie fires according to the passage?
A.wet weatherB.hotter summers
C.low temperaturesD.cold winters
2. What can we learn about zombie fires from Paragraph 2?
A.Where flames broke out provided the clue.
B.Changing climate plays a role in the zombie fire threat.
C.Zombie fires are less likely to happen after very warm summers.
D.It is of little use comparing firefighter reports with satellite images.
3. What conclusion will be possibly made based on the last paragraph?
A.It is important to understand zombie fires.
B.Zombie fires are likely to be under control soon.
C.Firefighters cannot do much to stop the zombie fires.
D.We still have much to learn about the warming climate.
4. Which of the following could be the suitable title of the passage?
A.“Zombie“ wildfires do great damage to land
B.“Zombie” wildfires release greenhouse gases
C.“Zombie“ wildfires sparked by human actions

文章大意:这是一篇说明文。文章介绍森林大火。不是所有的森林火灾都是一样的。在正确的条件下,如果安全进行,火灾可以创造许多环境效益,并有助于防止更大的、无法控制的野火。

【推荐1】The public nowadays has a misunderstanding of forest fires, believing that fire s should be kept out of every type of forest. Many of us can recall Smoky the Bear’s famous warning: “Remember, only YOU can prevent forest fires”. However, that’s not always the case. Under the right conditions, and when conducted safely, fire can create many environmental benefits as well as help prevent larger, uncontrollable wildfires.

After a forest fire, many wildlife species will move into recently burned areas to feed on these newly available foods. Some reptiles and amphibians such as the pine snake prefer forests frequently burned by fire. As Herbert Stoddard put it, “One of the most harmful things modern man has done to birds has been his attempt to exclude fire from fire-type pine(松树) forests. Within a few years most forests choke up with bushes, lose their prairie-like vegetation(草原般植被) and can no longer support birds dependent on periodic burning for their food supply and proper cover.”

If you are asked to picture the forest floor, what do you see? Pine needles, cones, leaves, branches might come to mind-all sources of fuel. If these fuel sources build up without any type of removal, the ‘fuel load’ can lead to fires catastrophic to forests and people alike. In contrast, prescribed fire can be used by forest professionals every couple of years to keep forest fuels at an appropriate and manageable level. They can also minimize the spread of pest insects and disease and remove unwanted tree and plant species. Plus, they can create and maintain important wildlife habitats rich in grasses and promote the growth of trees, wildflowers and other various plants.

Many organizations and agencies work to promote fire on the landscape when and where appropriate. Smoky Bear even has an updated warning: “Only You can Prevent Wildfires,” as the Forest Service has over the last few decades developed policies and procedures to include prescribed fire as a management tool, as well as continuing their work to prevent and fight wildfires.

1. Why did the author mention Smoky the Bear’s warning?
A.To raise people’s awareness of forest protection.B.To illustrate a conventional wisdom.
C.To show the significance of fire prevention.D.To introduce the topic of the passage.
2. What can benefit birds according to Herbert Stoddard?
A.Forest bushes.B.Fuel sources.C.Periodic burning.D.Pine forests.
3. What is the purpose of prescribed fire?
A.To keep the forest balance.B.To keep the fuel rich in the forest.
C.To put out wildfires.D.To remove tree and plant species.
4. What might be the best title for the passage?
A.Why Not Keep The Forest Fire BurningB.Not All Forest Fires Are Created Equal
C.Where There Is Smoke There Is A FireD.One Match Can Start A Forest Fire

文章大意:这是一篇说明文。文章讲了如何在突如其来的飓风中生存下来。

【推荐2】Can you survive an unannounced storm? Although there is expert broadcasting and we are equipped with cell phones, there’re still some instances(情况) when the violent weather takes us by surprise.

While most Atlantic hurricanes form off the coast of Africa giving plenty of early warning, sudden Caribbean and Gulf of Mexico hurricanes form and move rapidly in less than a day’s time, endangering everyone and everything in their path.

Oil workers were trapped off the shore when sudden storms appeared. Natural scientists have been stuck in coastal areas without storm warning. Ten years ago a Texas National Guard group was trapped on the beach by rain-forced flooding and had to ride out(经受的住) a major hurricane during a training exercise. There’ve been a few instances when travelers were trapped on an island or in a coastal area and unable to escape in time.

Escaping from the storm-threatened areas is generally a choice for most of us—but not for all. Each year thousands of islanders across the Caribbean face the danger of hurricanes without so much as a public shelter to hide in. Most ride out the storm in their homes.

But there’re a few things you can do to prepare yourself for some unexpected emergencies. Being prepared for the unexpected may be your best and only defense. If you’re headed outdoors for a few days or weeks, you should always carry a flashlight (手电筒) with extra batteries, a Beidou device (装置), and a basic medical box. If you’re traveling in your car, remember you may suffer high winds. You’d better not stay inside to avoid being blown away along with your car. Keeping your head and your courage up is essential to survival in any type of danger. Let common sense guide you and always be prepared for the worst.

1. According to the text, most Atlantic hurricanes ________.
A.form in the Caribbean SeaB.develop off the coast of Africa
C.come from Gulf of MexicoD.are from the Pacific Ocean
2. What is the third paragraph mainly about?
A.People trapped by sudden storms.B.The bad situations of oil workers.
C.The Texas National Guard group.D.The danger of traveling on an island.
3. What can we learn from the passage?
A.We can get through the storm because of the expert broadcasting.
B.Being prepared for the unexpected is likely to be our best and only defense.
C.Escaping from the storm-threatened areas is a choice for all of us in general.
D.We should stay inside the car to avoid being blown away in high winds.
4. What is the purpose of the last paragraph?
A.To give some advice.B.To encourage traveling.
C.To give some warnings.D.To understand the danger of storms.
5. In which part of a website would you most probably find the passage?
A.Science.B.Sports.C.Life.D.Culture.

【推荐3】Angus, Doris, Gabriel and Kamil are some of the 21 names that have been chosen to be given to storms in the UK in the 2016/17 season.

The Met Office, the UK's national weather service, decided to give storms boys' and girls 'names in 2015 in the same way as they did in America.

The Met Office hopes that naming big storms will make people more aware(意识到) of them and how dangerous they can be. Derrick Ryall, from the Met Office, said,“We have seen how naming storms elsewhere in the world raises people's awareness of storms before they break. ”

In the past,the same UK storm could be given different names by different organizations. “We noticed that many organizations during the last couple of winters started giving names to them.Think back to the St Jude's Day storm in 2013,and the so-called(所谓的)Hurricane Bawbag in Scotland in 2011.But it led to confusion(混淆),”a Met Office spokeswoman said.

According to the Met Office, there is a name for each letter of the whole alphabet (字母表),except for Q, U, X, Y and Z. That is the same as the naming tradition used in America. And not all storms will be big enough to get names-only those expected to cause great damage(损失)。

If there are more than 21 storms in a year,the Met Office will start again with another name beginning with “A”。 However, according to Met Office spokeswoman Lindsay Mears, "It's less possible we would get through the whole alphabet in one season. We had 14 storms in the very bad winter of 2013/14, and if the naming system had been in operation then we wouldn't have used the whole alphabet. ”

1. Why are storms in the UK named?
A.To increase public awareness of them.

2. examples are given in paragraph 4 to show______.
A.There are many storms to name in a year.

A.Storms will be given names whatever their sizes.
B.Serious storms will be given boys' names.
C.21 letters will be used to begin the names.
D.21 names will be given at most in a year.
4. What can be learned from Lindsay Mears?
