世界上第一艘零排放货船

田静

挪威的一家公司推出全球第一艘电动无人驾驶货船，这对引领航运业走向自主航行和零排放航运起着非常重要的作用。

1 A Norwegian company has created what it calls the worlds first zero?emission， autonomous cargo ship. Developed by chemical company Yara International， the ship was designed to reduce emissions of pollutants and greenhouse gases， and move freight （货运） away from roads to the sea.

2 The shipping industry accounts for between 2.5% and 3% of global greenhouse gas emissions， according to the International Maritime Organization. Nearly all of Norways electricity is generated by hydroelectric power （水力发电）， which is generally considered to have much lower carbon emissions than burning fossil fuels， although it still produces

greenhouse gases.

3 Capable of carrying 103 containers and with a top speed of 13 knots， it will use a

7 MWh battery， with about a thousand times the capacity of one electrical car. The ship will be charged near the port before sailing to container harbors along the coast and then back again， replacing 40，000 truck journeys a year.

4 As well as providing a greener option compared to conventional cargo ships， there is

no crewman， which means it will be more cost?effective to operate. Initially， loading and unloading the ship will require humans， but gradually， all loading， discharging （卸货）， and some other operations will also be eventually operated using autonomous technology. That will involve developing autonomous cranes and carriers， which are the vehicles that place containers onto ships.

5 According to researchers， fully autonomous vessels are the future. But there are many challenges to overcome before autonomous ships can be used for commercial long sea journeys. Navigating traffic in large ports could be a major obstacle.

6 Without a crew onboard to carry out maintenance checks， autonomous ships would need built?in self?diagnosing systems with the ability to detect and fix problems， or call for human assistance.

7 Although Yara International has no plans to add more autonomous ships to its operations， we may see more elements of AI technology used on commercial ships in the future. Elements are already being used in shipping today when it comes to the voyage and well see more partly autonomous elements added.

Ⅰ. Difficult sentences in the text

1. Developed by chemical company Yara International， the ship was designed to reduce emissions of pollutants and greenhouse gases， and move freight away from roads to the sea. 該船由雅拉国际化工公司开发，旨在减少污染物和温室气体的排放，并将货物从公路转移到海上。

【点石成金】本句中，Developed by chemical company Yara International为过去分词短语作状语，逻辑主语the ship和develop之间是动宾关系。

2. That will involve developing autonomous cranes and carriers， which are the vehicles that place containers onto ships. 那将涉及开发自动化的起重机和运载工具，它们是将集装箱装载到船上的运输工具。

【点石成金】本句有两个that，第一个that作代词，指代前面提到的一件事情；
第二个that引导的是定语从句，that在从句中作主语，从句修饰先行词the vehicles；
which引导的是一个非限制性定语从句，在从句中作主语。

Ⅱ. Text?centered chunks

be designed to do 为做……而设计的

account for （数量上、比例上） 占……

be generated by 由……生产

compare to与……相比较

call for 要求；
需要

add...to 把……加到……中去
