广东省梅州市部分学校2023-2024学年高二下学期4月期中英语试题

阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。

An international team of astronomers used a database combining observations from the best telescopes in the world  (detect) the signal from the active supermassive black holes of dying galaxies(星系) in the early universe. The  (appear) of these active supermassive black holes is related to changes in the host galaxy. This means a black hole could have far reaching effects  the evolution of its host galaxy.

The Milky Way Galaxy  we live includes stars of various ages, including stars still forming. But in some other galaxies, (know) as elliptical(椭圆的) galaxies, all of the stars are old and about the same age. This indicates that early in  (they) histories elliptical galaxies had a period of rich star formation that suddenly ended. Why this star formation stopped in some galaxies  not others is not well understood. One possibility is that a supermassive black hole disrupts(瓦解) the gas in some galaxies, (create) an environment unsuitable for star formation.

To test this theory, astronomers look at distant galaxies. Due to the limited speed of light, it takes time for light to travel across the void of space. The light we saw last night from an object 10 billion light years away  (travel) for 10 billion years to reach Earth. Thus the light we see today shows us what the galaxy looked like when the light left that galaxy 10 billion years ago. So looking at distant galaxies is like looking back in time. But the longer distance also means that distant galaxies look  (small), making study more difficult.

    Google's new artificial intelligence can defeat both humans and other AIs. Fortunately, the only war zone where it fights and wins is the ancient board game Go(围棋).

    AlphaGo Zero, developed by Google-owned DeepMind, is the latest AI program. The original AlphaGo defeated Go master Lee Sedol last year, and AlphaGo Master, an updated version, went on to win 60 games against top human players. What's different about AlphaGo Zero is that it became potentially the world's best Go player without any help from humans.

    The program AlphaGo Zero started off knowing only the basic rules and then played millions of games against itself in just a few days. After almost five million games played against itself, AlphaGo Zero could outplay humans and the original AlphaGo. After 40 days, it was capable of beating AlphaGo Master.

The program learned the strategies humans accumulated over thousands of years in a matter weeks and also developed nontraditional strategies and moves that beat the techniques of the human masters, leaving them astonished. "At each stage of the game, it seems to gain a bit here and lose a bit there, but somehow it ends up slightly ahead, as if by magic," said Andrew Jackson of the American Go Association

    DeepMind says it has plans for the technology behind AlphaGo Zero beyond just defeating all over an ancient game board. "In the end, we want to apply these breakthroughs to helping solve all sorts of pressing real world problems like designing new materials," said Demis Hassabis, co-founder and CEO of DeepMind, in a statement.

    That sounds great, but just as a precaution, let's take the advice of Elon Musk and Stephen Hawking and keep any super-fast learning AI away from the nuclear launch codes for now.

    A sea turtle named Herman, an octopus called Octavia, and a seal named Lidia all spent this summer at the Smithsonian's National Zoo in Washington, D.C. But unlike the zoo's other residents, they are not real animals. These creatures are actually huge sculptures and they're made entirely out of plastic trash from the ocean.

    These giant artworks, along with 14 others, are part of a traveling exhibit called “Washed Ashore: Art to Save the Sea”. The Washed Ashore project, led by artist Angela Haseltine Pozzi, works to raise awareness about the problem of plastic pollution in Earth's oceans.

    More than 315 billion pounds of plastic litter the world's oceans today. Most of the plastic is garbage from towns and cities, as well as trash that people leave on beaches, rainwater, winds, and high tides bring the trash into the ocean or into rivers that lead to the ocean. Once it is under the waves, the plastic begins to break up into smaller and smaller pieces. It often collects in spots called garbage patches, which spread over large areas of the ocean.

    Thousands of marine animals--including whales, sea turtles, and fish--die each year from eating or getting stuck in plastic bags and other items. Plastic pieces can also injure coral and kill sea grass.

    Washed Ashore and other organizations are working to stop that from happening. Since 2010, Washed Ashore volunteers have collected 38,000 pounds of plastic trash from more than 3000 miles of beaches. They helped Pozzi create more than 60 sculptures of marine creatures that were harmed by plastic pollution.

    The artworks on display at the National Zoo include a 20-foot-long coral reef, a 12-foot-long shark, and a 16-foot-long parrot fish. Each one is made from hundreds of pieces of trash like water bottles and sunglasses.

    “These sculptures are a powerful reminder of our personal role and global responsibility in preserving biodiversity(生物多样性) on land and in the sea,” says Dennis Kelly, director of the National Zoo.

    Steven Stein likes to follow garbage trucks. His strange habit makes sense when you consider that he's an environmental scientist who studies how to reduce litter, including things that fall off garbage trucks as they drive down the road. What is even more interesting is that one of Stein's jobs is defending an industry behind the plastic shopping bags.

    Americans use more than 100 billion thin film plastic bags every year. So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts(收银台) . The bags are prohibited in some 90 cities in California, including Los Angeles. Eyeing these headwinds, plastic-bag makers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume.

    Among the bag makers' argument: many cities with bans still allow shoppers to purchase paper bags, which are easily recycled but require more energy to produce and transport. And while plastic bags may be ugly to look at, they represent a small percentage of all garbage on the ground today

    The industry has also taken aim at the product that has appeared as its replacement: reusable shopping bags. The stronger a reusable bag is, the longer its life and the more plastic-bag use it cancels out. However, longer-lasting reusable bags often require more energy to make. One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic.

    Environmentalists don't dispute(质疑) these points. They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years.

Bees (蜜蜂) touch our lives in ways we may not realize. They are responsible for as much as one third of the food that we eat, and even play a role in growing the cotton (棉花) used in much of our clothing. {#blank#}1{#/blank#} Here's how you can help:

1. Plant more flowers

Bees depend on garden flowers to ensure they have different kinds of diet. By planting flowers in your garden you can create a pleasant place for bees. {#blank#}2{#/blank#} Another idea is to add hanging baskets of flowers next to your front door.

2. Find a space for a beehive (蜂窝) in your garden

Many would-be beekeepers find it difficult to find a safe space for their bees. If you have some space, contact your local beekeeping organization. {#blank#}3{#/blank#} You will be surprised what a difference a beehive will make to your garden.

3. Give bees water

{#blank#}4{#/blank#} They use water to produce food for their bee families and control the temperature in their hives. Bees look for a clean source of water. Leave out containers filled with clean water in your outdoor spaces and refresh them often.

4. Be bee friendly

Bees are good neighbors, and only sting (蜇) when they feel threatened. Beekeepers wear protective clothing when they are dealing with bees. If a bee flies in front of you when unprotected, do not flap (拍打) your hands. {#blank#}5{#/blank#} The bee will soon lose interest.

A. Stay calm and move slowly away.

B. Fight the diseases that affect bees.

C. They could find a beekeeper in need of a site.

D. One way to help bees is to buy local produce.

E. Like every living creature, bees need water to survive.

F. But more than one quarter of the species is facing extinction.

G. You don't even need a garden space to attract bees; your window box will do.
