Rotten seaweed is starting to pile up on beaches across the Caribbean. The uncontrolled blooms of sticky brown algae（藻类）called sargassum have become an annual disaster for the coastal areas. Removing seaweed and sending it to the landfill is costly and takes up declining space in landfills. Luckily, a company in Grenada, a small island nation in the Caribbean, has a better idea.
The company that would like to use Grenadian sargassum is SarGas, a start-up founded in 2023 to harvest the sargassum before it hits the beaches and turn it into a renewable source of fuel. The company has set up a small machine called Digester that uses bacteria to swallow sargassum and release methane（甲烷）, the main component of natural gas.
Instead of letting the methane escape and warm the planet, as it would if the sargassum rotted on the shore or in a landfill, SarGas collects the gas and uses it to fuel the oven at a
local bakery. Now the start-up is applying for a permit to build a bigger Digester that would power a biogas-fueled generator（发电机）to make electricity for Grenadians.
Generating electricity this way would be cheaper and cleaner, said SarGas CEO Benjamin Nestorovic. Almost all Grenadian electricity is made from generators running on imported diesel（柴油）, which causes pollution and forces Grenadians to pay some of the highest electricity rates on Earth. That's starting to change as Grenada installs solar panels, but biogas complements solar, because the sargassum-based fuel can generate electricity at night.
The first planned SarGas generator would use 5,000 to 8,000 tons of sargassum per year. It could generate 160 kilowatts of power, which is about half a percent of Grenada's peak demand. By saving diesel and preventing methane emissions at the landfill, it would avoid the equivalent（等量）of about 2,000 cars' worth of greenhouse gas emissions.
1. How does the machine Digester work? （）

D. By breaking seaweed down for energy.
2. What does the underlined word "complements" in Paragraph 4 mean? （）
A. Interacts with.
B. Keeps up with.
C. Competes with.
D. Pairs well with.
3. What effect will the SarGas generator have on Grenada? （）
A. It will remove the pressure of local landfills.
B. It will address a national environmental issue.
C. The nation will depend on imported fossil fuels.
D. The nation will offer new economic opportunities.
4. Which of the following is a suitable title for the text? （）
A. From Seaweed to Power
B. From Rubbish to Digester
C. Calling for Cleanup in Beaches
D. Turning Sargassum into Charity

语篇解读 本文是一篇说明文。文章主要介绍了加勒比海地区海滩上堆积的马尾藻给沿海地区带来困扰,一家名为SarGas的公司利用马尾藻生产燃料发电,变废为宝,解决环境问题。
1.D 细节理解题。根据第二段“The company has set up a small machine called Digester that uses bacteria to swallow sargassum and release methane (甲烷),the main component of natural gas.”可知,Digester机器通过分解海藻来获取能源。故选D。
2.D 词义猜测题。根据第四段“That's starting to change as Grenada installs solar panels, but biogas complements solar, because the sargassum-based fuel can generate electricity at night.”可知,太阳能白天发电,而沼气夜间发电,二者相互配合,“complements”与“Pairs well with(与……很好地配合)”意思相近。故选D。
3.B 推理判断题。根据第一段“Rotten seaweed is starting to pile up on beaches across the Caribbean. The uncontrolled blooms of sticky brown algae (藻类) called sargassum have become an annual disaster for the coastal areas.”以及最后一段“By saving diesel and preventing methane emissions at the landfill, it would avoid the equivalent (等量) of about 2, 000 cars' worth of greenhouse gas emissions.”可知,SarGas发电机将改善格林纳达的一个全国性环境问题,故选B。
4.A 标题归纳题。通读全文可知,文章主要讲述SarGas公司将海滩上堆积成灾的马尾藻转化为能源。故选A。
