2 . Canada geese are a common and plentiful North American bird found in many urban parks, golf courses, airports, or areas with large lawns near water. They are a large waterbird with a fairly brown body, pale breast, and long black neck with white cheeks.

Canada geese are particularly attracted to urban areas for the many grassy lawns near small bodies of water. They can often be seen feeding on lawns or playing in shallow water by tipping forward and extending their necks underwater to reach for plants. Canada geese prefer to gathering in large flocks (群) and can be seen flying over in the classic V formation.

In Chicago, Canada geese may remain in the city throughout the year, although some geese get used to moving long distances to more southern sections for the winter or northward in spring to breed. Each breeding season, pairs build large open cup ground nests and lay 2 to 8 eggs which are raised in a single brood (窝). Urban habitats are also attractive to this species as neatly-maintained lawns make it easy when grazing with young to keep watch for approaching enemies. It is, however, their use of these urban areas that often leads to conflicts with humans.

As Canada geese numbers rise, so do their conflicts with humans. Canada geese’s daily activities may damage gardens and landscaping. Geese may also cross roads when searching for food or walking between nesting sites and bodies of water, slowing movement or posing a potential risk on the roadway. Although direct injuries by fierce geese are uncommon, people sometimes fall and pick up injuries when surprised by a charging goose. Additionally, people often feed the birds. Not only are the types of food people typically provide, such as bread, unhealthy for the birds, but this encourages high concentrations of geese leading to more harmful behavior and higher risk of diseases. Lastly, plane-bird conflicts are estimated to be rising, likely due to increasing numbers of planes, but also increases in populations of certain bird species, including Canada geese. Although crashes rarely result in an accident, they often cause costly damage to planes.

4 . Why should mankind explore space? Perhaps the best answer lies in our genetic makeup as human beings. What prompted our distant ancestors to move from the trees into the plains, and on into all possible areas and environments?    1    . The wider the distribution of a species, the better its chance of survival.

Exploration also allows minerals and other potential resources to be located. Additional resources are always beneficial when used wisely, and can increase our chances of survival. Knowledge or techniques acquired through exploration, or preparing to explore, filter from the developers into society at large.     2    . Also, we have already benefited from other by-products, including improvements in earthquake prediction — which has saved many lives —   in satellites used for weather forecasting and in communications systems. Even non-stick saucepans and mirrored sunglasses are by-products of technological developments in the space industry!

    3    . The chances of a large comet hitting the Earth are small, but it could happen in time. Such strikes in the past may account for the extinction of dinosaurs and other species. Human technology is reaching the point where it might be able to detect the possibility of this happening, and enable us to minimize the damage, or prevent it completely, allowing us as a species to avoid extinction.

In certain circumstances, life on Earth may become impossible: over-population or wide spread diseases, for instance, might eventually force us to find other places to live. While the earth is the only planet known to sustain life, surely the adaptive ability of humans would allow us to inhabit other planets and moons. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.     4    .

A．The techniques may have medical applications which can improve the length or quality of our lives.

B．Space allows us to expand and succeed: for the sake of everyone on the earth, now and in the future, space exploration is essential.

C．The mysterious space objects varying in size have been fascinated scientists and scholars for years.

D．It appears that we are driven to ensure the success and continuation of not just our own genes, but of the species as a whole.

E．Therefore it still poses a problem for us human beings whether to explore the space at the cost of our own homelands.

F．While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers.

There’s a rarely-visited, dusty corner of the world where something magical happens. The place, which looks like Mars with its red rock landscape, is the Tatacoa Desert, in Colombia.

Tatacoa is located in the region of Huila, south of the country’s capital Bogotá. Although Tatacoa, with its protruding cacti and red rippled rocks, is called a desert, it is in fact a dry tropical forest. But the exciting, and very     1    , feature of this desert, is what happens above it, at night.

Thanks to its remote location — it’s almost 30 miles and an hour’s drive over bumpy winding roads to the nearest town — Tatacoa has no light pollution to     2     with the night sky.

Up to 88 constellations (星座) are visible on a clear night, as well as both hemispheres — something that happens nowhere else in the world.

The warm and dry climate helps with stargazing; a     3     atmosphere, which happens in dry spots or places of high elevation, decreases something called scintillation, which is when a star’s light rises and falls rapidly. It’s why stars twinkle, which looks beautiful but isn’t so great for astronomers.

Not only is Tatacoa a natural wonder, but the DIY observatory that’s run by a Colombian man named Javier Fernanda Rua Restrepo has become a star     4     too. In fact, this humble building attracts stargazers from all over the world, from China to Iceland to Australia. And Restrepo has also become well-known in astronomer circles, with a few scientists     5     their own telescopes to support the grassroots observatory.

The Colombian, who is     6     from Cali, fell in love with the stars thanks to his father’s interest in astronomy and science, and first visited Tatacoa in 1997, to try to see the Comet Hale-Bopp. He stayed for a couple of days before heading back to his hometown. But within a month, he returned to Tatacoa — and never left, camping out for weeks on end     7     for the night to come so that he could watch the stars.

At first Restrepo had worked at the Colombian government’s observatory, which he helped staff for 15 years. But after budget cuts meant he lost his job, he figured he would     8     build his own.

In 2015, Restrepo opened the doors to his observatory — Tatacoa Astronomia — with just one telescope. Now, as Colombia has grown in     9     as a tourist destination, hundreds flock to Restrepo’s star party, which he holds once a year in July.

Tatacoa Astronomia is only open on starry nights, and Restrepo remains the sole employee. But that doesn’t distract from the intimacy and the specialness of the place. The structure sits on a small patch of land that Restrepo bought himself, and is cordoned (隔离) off by tarpaulin (油布) to add an extra sense of     10     and intrigue (阴谋) for visitors.

“The stars… they put my life into its tiny perspective,” he says, “and they constantly remind me there are greater things out there.”

8 . Wildlife populations around the world are facing dramatic declines, according to new figures that have led environmental campaigners to call for urgent action to rescue the natural world. The 2022 Living Planet Index (LPI), produced by the Zoological Society of London (ZSL), reveals that studied populations of mammals, birds, reptiles (爬行动物) and fish have seen an average decline of 69 per cent since 1970, faster than previous predictions. The LPI tracked global biodiversity between 1970 and 2018, based on the monitoring of 31,821 populations of 5230 vertebrate (脊椎动物) species. Mark Wright of WWF says the degree of decline is destructive and continues to worsen. “We are not seeing any really positive signs that we are beginning to bend the curve of nature,” he says.

Freshwater vertebrates have been among the hardest-hit populations, with monitored populations showing an average decline of 83 per cent since 1970. The Amazon pink river dolphin, for example, has experienced a 65 per cent decline in its population between 1994 and 2016. Meanwhile, some of the most biodiverse regions of the world are seeing the steepest falls in wildlife, with the Caribbean and central and south America seeing average wildlife population declined by 94 per cent since 1970. Habitat loss and reduction is the largest driver of wildlife loss in all regions around the world, followed by species overexploitation by hunting, fishing or poaching (偷猎).

In December, governments from around the world will gather in Montreal, Canada, for the COP15 Biodiversity Framework, a much-delayed summit that aims to agree on a set of new targets intended to prevent the loss of animals, plants and habitats globally by 2030. “This is a once-in-a-decade opportunity that’s coming up,” says Robin Freeman of ZSL. He says it is vital that governments use the summit to agree on “meaningful, well measurable targets and goals”. “We need governments to take action to ensure that those goals deal with the complicated combined threats of climate change and biodiversity, in order for us to see a meaningful action,” says Freeman. But some researchers are critical of the LPI’s use of a headline figure of decline, warning it is easy to be misunderstood.

The findings don’t mean all species or populations worldwide are in decline. In fact, approximately half the populations show a stable or increasing trend, and half show a declining trend. “I think a more appropriate and useful way to look at it is to focus on specific species or populations,” says Hannah Ritchie at Our World in Data. But Wright says the LPI is a useful tool that reflects the findings of other biodiversity indicators. “All of those show they all scream there is something going really very badly wrong,” says Wright.

Is Banning Single-use Plastic the Right Option?

The harmful effects of using plastic are becoming increasingly apparent. Plastic does not decompose, but breaks down into smaller and smaller particles. It threatens our nature as well as our health. One popular solution to the problem is to prohibit single-use plastics. In the UK, supermarkets are being encouraged to set up plastic-free aisles, in which the food is displayed loose, and shoppers are encouraged to make more environmentally-friendly choices in packing and transporting their food.

Such plans are well-intentioned, but it may not be beneficial to eliminate(清除) the use of single-use plastic altogether. One of the fields where single-use plastic has a vital role is the food industry. When food or fresh goods are packed in plastic, they are protected and preserved, helping them remain fresher and keeping them from spoiling. Single-use plastic is also crucial in the medical industry. This is not just because of its low cost. It helps to prevent the spread of infection and that is the biggest benefit of the material in the medical field.

Replacing plastic with other materials is neither simple nor straightforward, mainly due to the challenge of finding an alternative that combines all the most desirable plastic properties. For example, glass products are a potential alternative, but cleaning them would be extremely expensive while increasing the risk to health. Another issue is that alternative materials to plastic are often more environmentally harmful than plastic. Take paper bags, for example. Research by the Northern Ireland Assembly shows four times more energy is required to manufacture a paper bag than a plastic bag. If people respond by simply using other materials, a ban on single-use plastic can end up making the problem worse.

Clearly there is a need to reduce plastic waste and its impact on the environment. However, simply banning their single use may not be the best option.
