In the last 500 million years, there have been five times when life on Earth has almost ended. The reasons for extinctions are varied. According to scientists, they include volcanic eruptions, asteroids hitting the Earth from space, changes in sea levels, the decrease of the oxygen content of the sea and global warming. 课后巩固 多维提能 Many scientists say we are now entering the Earth's sixth mass extinction. This time, human activity will be to blame. Although it is not unusual for species to die out naturally, the rate at which this is now happening is cause for concern. A 2015 study in the US, looked at how quickly species die out due to natural causes, that is, the “background extinction rate”．They found that human activity is causing species to die out 1，000 times faster than normal. There is a long list of reasons why so many species are dying out: air and water 课后巩固 多维提能 pollution, forests being destroyed, factory farming and overfishing. It is clear that human activity has negatively affected all other species on Earth, including animals and plants. If a sixth mass extinction occurs, scientists who have studied the issue believe that up to three quarters of all species on Earth could die out. 课后巩固 多维提能 Can a sixth extinction be averted？Experts say that it is not yet too late, if we take action now. This would mean we have to significantly change the way we live. We need to change how we work and travel by using cleaner, more natural sources of energy, such as wind and solar energy. We also need to improve our farming methods to reduce water, air and land pollution. In short, if we want to survive, we need to stop destroying the planet that we live on and start to protect it. 课后巩固 多维提能 1．Which was NOT the reason that caused the five extinctions? A．Volcanic eruptions. B．Changes in sea levels. C．Global warming. D．Human activities. √ 3 4 2 1 课后巩固 多维提能 2．What can we know from paragraph 2? A．Human activity has done harm to nature. B．It is unusual for species to die out naturally. C.Species die out quickly, mostly due to natural causes. D．There are few reasons why so many species are dying out. √ 3 4 2 1 课后巩固 多维提能 3．What does the underlined word “averted” in paragraph 3 mean? A．Tolerated.　　 B．Changed. C．Scheduled.

D．The effects of the sixth extinction on us. √ 3 2 1 4 课后巩固 多维提能 课后巩固 多维提能 Females stay in their family groups for their whole lives, and the males will stay in their family groups until they become teenagers.Then the males will move out and live together with other males.The calves (小象) are raised by their relatives as well as their mum, much like we used to. 课后巩固 多维提能 One of the typical characteristics (特点) of elephants is that they seem to have strong social connections.There have been reports of elephants developing lifelong friendships with each other, and they even mourn the death of their loved ones.For example, mother elephants have been seen grieving over calves born dead, and some elephants have even been found returning to, and wandering near places where their friends and family members died. 课后巩固 多维提能 What's amazing is that elephants always stay in touch in their special way.They will communicate with each other by making sounds, which are within human hearing range.But we know that they also use a very low-frequency (低频的) sound that can travel a long distance.We believe that when elephants separate from each other in groups, they will keep in touch with each other using low-frequency sound, finally meeting back up together again. 课后巩固 多维提能 Elephants have a unique social structure that seems like our own.They face many of the struggles of co-existence and emotional problems as we do.With less than 650，000 elephants remaining on the planet, they are in real danger of extinction, and it's our job to protect them. 【解题导语】　本文是一篇说明文。文章介绍了大象与人类之间令人惊讶的相似性，包括它们的社会结构、情感表达及交流方式，并强调了保护这一智慧物种的重要性。 课后巩固 多维提能 3 4 5 6 7 8 2 1 1．Which of the following statements is true? A.Female elephants play a very important role in family groups. B．Calves are only raised by their mothers. C．Elephants enjoy living alone by nature.

A．Feeling sad about. B．Feeling angry about. C．Feeling shocked about. D．Feeling nervous about. √ 课后巩固 多维提能 3 4 5 6 7 8 1 2 解析：词义猜测题。根据画线词下文“For example, mother elephants have been seen grieving over calves born dead...where their friends and family members died.”可推知，大象之间会发展出终生的友谊，它们甚至会哀悼亲人的死亡。因此，画线词意为“哀悼”，与A项意思相同。 课后巩固 多维提能 4 5 6 7 8 2 1 3 3．How do elephants stay in touch with each other? A．By using only low-frequency sound. B．By touching their trunks. C．By making sounds of different frequencies.

A．Elephants：Our Friends! B．Elephants：In Real Danger of Extinction C．Female Elephants：Head of the Family D．Elephants and Humans：Much Alike 解析：标题归纳题。通读全文，尤其是第一段内容可知，文章主要强调了大象与人类在社会结构、情感和行为上的相似性。因此，D项最适合作文章标题。 √ 课后巩固 多维提能 B Several days of unusually warm weather in northern Greenland have caused rapid melting(融化). “Temperatures have been running around 15.5 ℃. It is warmer than normal for this time of year，” scientists said. The amount of ice that melted in Greenland between July 15 and July 17 alone—6 billion tons of water per day—would be enough to fill 7.2 million Olympic-sized swimming pools, according to the report from the US National Snow and Ice Data Center. To put it another way, it was enough to cover the whole state of West Virginia with a foot of water. 课后巩固 多维提能 For the scientists out on the ice sheet (冰盖), the warmth has been alarming. “It really makes me anxious，” said Kutalmis Saylam, a scientist who is now working in Greenland. “Yesterday, we could hang about in our T-shirts, which was not really expected. Since Greenland holds enough ice, sea level would rise by 7.5 meters around the world if ice all melted.” 课后巩固 多维提能 In 2020, scientists found that Greenland's ice sheet had melted beyond the point of no return. “No efforts to prevent global warming can stop it from finally breaking into small parts，” said researchers. 课后巩固 多维提能 Aslak Grinsted, a climate scientist, said that they were trying to get flights into the camp so that they could ship out the ice cores (冰芯) they had collected. But the warmth is destabilizing the landing site. “The weather we are seeing right now is too hot for the ski-equipped planes to land，” Grinsted said. “So we store the ice cores in large caves we have made into the snow to protect it from the heat of the summer.” Scientists made use of the abnormal warmth while they were waiting, playing volleyball in their shorts on an ice sheet at the top of the world. 课后巩固 多维提能 Grinsted referred to the temperatures as a heatwave, and noted that the possibility of temperatures getting this hot was clearly connected to global warming. 【解题导语】　本文是一篇说明文。文章主要介绍了格陵兰岛北部连续几天温度上升导致冰川快速融化，这种状况令人担忧。 课后巩固 多维提能 3 4 6 7 8 2 1 5 5．How does the author support the topic of paragraph 1? A．By exploring reasons. B．By making comparisons. C．By designing the numbers. D．By doing some experiments. 解析：推理判断题。根据第一段中的“Temperatures have been running around 15.5 ℃.It is warmer than normal for this time of year”可知，作者通过比较气温来支持主题。 √ 课后巩固 多维提能 3 4 5 7 8 2 1 6 6．What did Kutalmis mean in paragraph 2? A．He disliked wearing a T-shirt. B．He was concerned about the warmth. C．He was deeply impressed by the ice. D．He was thirsty for enjoying the sea view. 解析：推理判断题。根据第二段中的“For the scientists out...said Kutalmis Saylam”可知，第二段中库塔尔默斯表明，他很担心气温变暖这件事。 √ 课后巩固 多维提能 3 4 5 6 8 2 1 7 7．What does the underlined word “destabilizing” mean in paragraph 4? A．Quitting.　　 B．Removing. C．Sheltering. D．Destroying. 解析：词义猜测题。根据第四段中的“But the warmth is destabilizing the landing site.”和“The weather we are seeing right now is too hot for the ski-equipped planes to land”可推知，气候变暖影响了飞机的着陆地点，画线词与D项意思最为相近。 √ 课后巩固 多维提能 3 4 5 6 7 2 1 8 8．What will the author probably do in the following paragraph? A．Recommend visiting Greenland. B．Describe how to ship out the ice core. C．Call on people to protect the environment. D．Plan to organize a sports meeting on ice. 解析：推理判断题。根据最后一段中的“global warming”可知，温度升高显然与全球变暖有关，由此可推知，作者在下一段中可能会呼吁人们保护环境。 √ 课后巩固 多维提能 Ⅱ.完形填空 (2025·青海名校联盟联考)The incident began early on November 27.A horse named Hank was _________________ in a narrow cave.Its owner, Dave, discovered Hank, and without hesitation, he _________________ called for help.What followed was the remarkable _________________ of neighbors and even nearby businesses.
