6 . Light pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.
Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial light at night — in combination with habitat loss, chemical pollution.invasive (入侵的) species, and climate change — is driving insect declines, " the scientists concluded after assessing more than 150 studies.
Insect population collapses have been reported around the world, and the first global scientific review published in February, said widespread declines threatened to cause a "catastrophic collapse of nature's ecosystems".
There are thought to be millions of insect species, most still unknown to science, and about half are active at night. Those active in the day may also be disturbed by light at night when they are at rest.
The most familiar impact of light pollution is moths (飞蛾) flapping around a bulb, mistaking it for the moon. Some insects use the polarisation of light to find the water they need to breed, as light waves line up after reflecting from a smooth surface. But artificial light can scupper (使泡汤) this. Insects are important prey (猎物) for many species, but light pollution can tip the balance in favour of the predator if it traps insects around lights. Such increases in predation risk were likely to cause the rapid extinction of affected species, the researchers said.
The researchers said most human-caused threats to insects have analogues in nature, such as climate change and invasive species. But light pollution is particularly hard for insects to deal with.
However, unlike other drivers of decline, light pollution is relatively easy to prevent. Simply turning off lights that are not needed is the most obvious action, he said, while making lights motion-activated also cuts light pollution. Shading lights so only the area needed is lit up is important. It is the same with avoiding blue-white lights, which interfere with daily rhythms. LED lights also offer hope as they can be easily tuned to avoid harmful colours and flicker rates.
What is discussed in the passage?A.Causes of declining insect populations. |
B.Consequences of insect population collapses. |
C.Light pollution: the key bringer of insect declines. |
D.Insect declines: the driver of the collapsed ecosystem. |
7 . To reduce coffee cup waste, Cup Club is already replacing millions of takeaway cups in the UK, while Recup in Germany, has performed a deposit system that simply adds a small extra fee to any coffee cup which is returned to the buyer after the cup is deposited in any registered collection point.
......
What does the word “which” in the last paragraph refer to?A.A collection point. | B.A deposit system. |
C.A small extra fee. | D.Any coffee cup. |
8 . The creators of the wall hope it will bring an urgently needed solution to the threats facing the African continent, creating 10 million jobs in rural areas, as well as preventing 250 million tons of carbon. The initiative is Africa-driven, which for those on the continent, is vital, and may hold the key to success. “The Great Green Wall…is about ownership, and that has been the failure of development aid because people were never identified with it,” said Elvis Paul Tangam, African Union Commissioner for the Sahara and Sahel Great Green Wall Initiative.“But this time they identify. This is the very thing of us!”
What does “us” underlined in Paragraph 3 refer to?A.African Unions. | B.All advocates. | C.Land owners. | D.All Africans. |
9 . A tree-planting initiative in Kenya has seen over 30,000 trees being planted. The Green Generation Initiative is a Kenyan charity that has been planting trees to counter climate change and the reduction in forest in the East African nation since 2016.
......
Speaking to world leaders at the recent United Nations Climate Conference in Glasgow (COP26), Elizabeth issued a serious warning on the threat of climate change. Over two million of Kenyans are facing climate related starvation. In 2025, half of the world’s population will be facing water shortage. The climate crisis will displace 80 million people in sub-Saharan Africa alone.
Elizabeth said, “I have been doing what I can. Inspired by the great Wangari Maathai, I founded a tree growing initiative that enhances food security for young Kenyans.” So far, they have grown 30,000 fruit trees to maturity, providing desperately needed nutrition for thousands of children. “Every day we see that when we look after the trees, they look after us. We are the adults on this Earth right now, and it is our responsibility to ensure that the children have food and water,” she added.
Which of the following can best describe Elizabeth Wathuti?A.Friendly and talented. | B.Caring and responsible. |
C.Honest and determined. | D.Ambitious and humorous. |
10 . Tree-planting, intended to help draw down carbon dioxide from the atmosphere, has become a synonym (同义词) for climate action. In our constant focus on trees, we’ve developed a fixed understanding: Trees absorb carbon dioxide, end of story. The reality is that trees don’t grow well alone. They exist within complex communities, helped along by each other as well as the animals they coexist with. The woodland isn’t nature’s only carbon sink: Grasslands and oceans also help reduce the carbon level and rely on a healthy amount of biodiversity.
That’s what the paper, published in Nature, wants to get across. Co-author Oswald J. Schmitz, a professor of ecology at Yale University, said trees might not be able to do their carbon-uptake job efficiently without the right animals in their ecosystem. That’s because animals animate the carbon cycle through their behavior and roles in the ecosystem. He added that the very presence of wild animals could cause feedback effects that change the ecosystem’s capacity to absorb, release, or transport carbon.
In Serengeti, for instance, the sharp decline in wildebeest (角马) population s during the mid-20th century allowed grass to grow wildly, eventually promoting wildfires that consumed 80 percent of the ecosystem annually and led to a net release of carbon dioxide into the atmosphere. When disease management and bans on illegal hunting helped animal populations recover, a greater share of the carbon stored in plants was consumed by wildebeest and released as waste, keeping it in the system and restoring the grassland as a carbon sink.
