Imagine that a cool bamboo-like grass can be used to make green energy. Scientists at Landuo Biotech, a business in Wuhan, have created one such plant recently. They name it “super giant reed” (超级芦竹).

Since 2012, the Landuo team have collected over 1,000 wild giant reeds for experiments. As a result, more than 40 varieties of super giant reed have been “born”. In the Landuo’s factory, hundreds of young reeds are grown in glass bottles. Fully grown, super giant reeds are cut and put in a special place without O₂. The Landuo team heat them up to make natural gas, which can then be used for energy.

Thanks to the scientists’ efforts, super giant reed has a biomass (生物量) three times that of wild giant reed. A kilogram of super giant reed also has 4,000 to 4,500 kilocalories (千卡) of energy. So, super giant reed is a great choice for taking the place of fossil fuels (化石燃料).

What’s more, growing super giant reed helps a lot. Planting 13,000 hectares of it can produce 0.45 to 1.5 million tons of fuel a year. 40 million hectares of super giant reed can be used instead of 2.2 billion (1 billion=1,000 million) tons of coal and can cut CO₂ emissions (排放) by 4 billion tons in China every year.

Super giant reed is also well-suited for growing on some land like beaches, wetlands and salty lands. Once a reed is planted, it can be cut and used many times during the next 15 to 20 years. By the end of 2024, over 3,300 hectares of super giant reed had been planted across 53 areas in China.

At present, China is developing this new energy source—super giant reed and we hope that it can help to make our planet cleaner and cleaner.

1.1.What is the right order according to paragraph 2? a.The super giant reeds are cut by the Landuo team. b.The super giant reeds are heated up to make natural gas. c.The Landuo team grow lots of young super giant reeds in glass bottles. d.The Landuo team put the super giant reeds in a special place without O2.

A a-b-c-d

B b-a-c-d

C c-b-d-a

D c-a-d-b

解析：选D。D 细节理解题 解析：首先定位第二段中超级芦竹的处理流程：①“hundreds of young reeds are grown in glass bottles”（在玻璃瓶中培育幼苗，对应选项 c）→②“Fully grown, super giant reeds are cut”（成熟后收割，对应选项 a）→③“put in a special place without O2”（放入无氧环境，对应选项 d）→④“heat them up to make natural gas”（加热制造天然气，对应选项 b）。因此顺序为 c-a-d-b，选 D。

2.2．How many kilocalories of energy does a kilogram of super giant reed produce?

A 1,000 to 1,500.

B 2,000 to 3,500.

C 4,000 to 4,500.

D 5,000 to 5,500.

解析：选C。C 细节理解题 解析：题干问 “每千克超级芦竹的能量”，定位第三段 “A kilogram of super giant reed also has 4,000 to 4,500 kilocalories of energy”，直接匹配选项 C，其余选项均无原文依据。

3.3．How does the writer support the main idea of paragraph 4?

A By listing numbers.

B By telling stories.

C By asking questions.

D By giving suggestions.

解析：选A。A 细节理解题 解析：第四段核心观点是 “种植超级芦竹益处多”，支撑该观点的内容为 “13,000 hectares”“0.45 to 1.5 million tons”“40 million hectares”“2.2 billion tons”“4 billion tons” 等具体数字，通过列数据（listing numbers）增强说服力，而非讲故事（B）、提问题（C）或给建议（D），故选 A。

4.4．In which part of a newspaper can you probably read the text?

A People.

B Science.

C Sports.

D Travel.

解析：选B。B 题细节理解题 解析：选项 A（People，人物版）聚焦人物故事，本文无人物事迹；B（Science，科学版）涵盖科技、新物种等内容，“超级芦竹” 是新型能源植物，属科学范畴；C（Sports，体育版）与运动无关；D（Travel，旅游版）涉及旅游信息，本文不涉及。故选 B。

5.5．What can be the best title for the text?

A Fossil Fuels

B CO2 Emissions

C Wild Giant Reed

D Super Giant Reed

解析：选D。D 主旨大意题 解析：文章围绕 “超级芦竹” 展开，从培育、特性、价值到种植现状，核心对象是 “超级芦竹”。A（化石燃料）是超级芦竹的替代对象，非核心；B（二氧化碳排放）是超级芦竹的作用效果，非主体；C（野生芦竹）是实验基础，非重点。故选 D。
