9 . In a small, rough shipyard on the Pacific coast of Costa Rica, a small team is building what they say will be the world’s largest ocean-going clean cargo ship.

Ceiba is the first ship built by Sailcargo, a company trying to prove that zero-carbon shipping is possible, and commercially available. Made largely of wood, Ceiba combines both very old and very new technology: sailing masts stand alongside solar panels, a uniquely designed electric engine and batteries. Once on the water, she will be capable of crossing oceans entirely without the use of fossil fuels, which sets her apart.

“The thing that is striking is the fact that she’ll have one of the largest marine electric engines of her kind in the world,” Danielle Doggett said. The system also has the means to capture energy from underwater propellers (螺旋桨) as well as solar power, so electricity will be available for the engine when needed. “Really, the only limit on how long she can stay at sea is water and food on board for the crew.”

Despite some hold-ups due to the global disaster, the team hopes to get her on the water by the end of 2024 and operating by 2025, when she will begin transporting cargo between Costa Rica and Canada.

“There are actually loads of innovations happening that could transform shipping emissions, but few companies are willing to apply them to building ships like Ceiba.” says Lucy Gilliam. “So it’s not that we don’t have great ideas. The problem that we have is that fossil fuels are still too cheap. And we don’t have the rules to force people to take up the new technology.”

When it comes to promoting this kind of boat, it has to be said that Ceiba is small for a cargo ship — tiny in fact. She will carry around nine standard shipping containers. She is also relatively slow. Being a world-first, there are some aspects of Ceiba’s design that have yet to be proven at sea.

1. What is unique about Ceiba as a cargo ship?

A．It is the world’s largest.	B．It is environment-friendly.
C．It is wooden with old technology.	D．It is modern with unique equipment.

2. What determines Ceiba’s length of staying at sea according to Danielle Doggett?

A．The size of the sail.	B．The weather of the ocean.
C．The power of the electric engine.	D．The quantity of the living supplies.

3. Why are companies unwilling to build ships like Ceiba?

A．The rules are disobeyed.	B．The fuels are affordable.
C．The bigger ships are preferable.	D．The innovations are distrusted.

4. What is the author’s attitude to the innovation of Ceiba?

A．Objective.

B．Doubtful.

C．Critical.

D．Favorable.
