A very important hydropower (水力发电) project started on Saturday in Xizang, China. The project is located on the lower part of the Yarlung Zangbo River. Chinese Premier Li Qiang announced the start at a special ceremony.

The ceremony happened in Nyingchi City, at the place where the dam for the Mainling hydropower station will be built. Many people attended, including government workers, company representatives, experts, and local people.

This big project will build five hydropower stations, one after another. It will cost about 1.2 trillion yuan. Most of the electricity made here will be sent to other parts of China, but some will also be used in Xizang itself. A new company, the China Yajiang Group, was set up in Beijing to help build and run these power stations well.

Premier Li Qiang visited Xizang before the ceremony. He said that building big national projects must be done with high quality. He added that these projects help the economy, improve people’s lives, and support all ethnic groups. He especially asked everyone to protect the environment while building. “Don’t harm nature,” he said.

He stated that the Yarlung Zangbo hydropower project was extremely important. He wants builders to use the best technology and materials. His goal is to make this a great project for the new era, while carefully protecting the river and land around it.

1.1.Where is the hydropower project located?

A In Beijing.

B On Yarlung Zangbo River.

C Out of Nyingchi City.

D In a new company.

解析：选B。B 细节理解题。根据第一段的“The project is located on the lower part of the Yarlung Zangbo River”可知，项目位置在雅鲁藏布江下游。干扰项 A（北京）是新公司成立地，C（林芝市）是仪式举办地，D（新公司）与位置无关；均属于张冠李戴。故选B。

2.2.What does the underlined word “It” in Paragraph 3 refer to?

A The project.

B Electricity.

C A company.

D The dam.

解析：选A。A 词意指代题。第三段首句介绍该项目将建设五个水电站，随后这句“It will cost about 1.2 trillion yuan”中的“It”显然指代前文的“this big project”。干扰项 B（电力）、C（公司）、D（大坝）均不符合语境；属于望文生义。故选A。

3.3.How much will the project cost?

A 12 trillion yuan.

B 1.2 trillion yuan.

C 120 billion yuan.

D 12 billion yuan.

解析：选B。B 细节理解题。第三段中明确给出“It will cost about 1.2 trillion yuan”。干扰项 A（12 万亿）和 D（120 亿）是对数字的偷梁换柱，C（1200 亿）虽数值接近但单位不符，属于缩小范围。故选B。

4.4.What does Premier Li Qiang care about most?

A Spending less money.

B Finishing the project fast.

C Building more big projects.

D Protecting the nature.

解析：选D。D 推理判断题。第四段中提到“He especially asked everyone to protect the environment while building. ‘Don’t harm nature,’ he said.”，他特别要求大家在建设的同时保护环境。“不要破坏自然，”他说。由此可知，他最在意的是保护自然环境。故选D。

5.5.What is the main idea of the passage?

A A new company in Beijing.

B A hydropower project in Xizang.

C Premier Li Qiang’s visit to Xizang.

D The Yarlung Zangbo River.

解析：选B。B 主旨大意题。全文围绕西藏雅鲁藏布江水电项目展开，介绍了项目启动、规模、意义等相关内容。干扰项 A（北京新公司）、C（总理访问西藏）、D（雅鲁藏布江）均为文中细节，属于以偏概全，无法概括主旨。故选B。
