Belfast is a peculiarly religious community. This may be said of the whole of the North of Ireland. About one-half of the people are convinced Protestants (清教徒) and the other half Catholics (天主教徒). Each party does all it can     1    (make) its own doctrines (信条) popular and draw the affections of the irreligious toward them.    2    hears constantly of the most touching instances of this passion. A week ago a vast crowd of Catholics assembled at Armagh to dedicate a new church; and when they started home again the roadways     3     (line) with groups of meek and lowly Protestants who stoned them     4    all the region round about was marked with blood. I thought that only Catholics argued in that way,    5    it seems to be a mistake.

Every man in the community acts like a minister and carries a brick to argue against     6    holds different ideas. The law has tried to break this up, but not with perfect success. The law says that persons uttering (说) irritating “party cries”    7    be fined forty shillings (先令) and costs. And so, in the police court reports every day, one sees these fines     8     (record). Last week a girl of twelve years old was fined the usual forty shillings and costs     9    claiming in the public streets that she was “a Protestant.” The usual cry is, “To hell with the Pope!” or “To hell with the Protestants!” according to the utterer's system of salvation.

One of Belfast's local jokes was very good. It referred to the uniform and inevitable fine of forty shillings and costs for uttering a party cry--and it is no economical fine for a poor man, either, by the way. They say that a policeman found a drunken man lying on the ground, up a dark alley,    10     (amuse) himself with shouting, “To hell with! To hell with!” The officer smelt a fine--informers get half.

“What’s that you say?”

“To hell with!”

“To hell with who? To hell with what?”

“Ah, ye can finish it yourself--it's too expensive for me!”

I think the seditious disposition (倾向), restrained by the economical instinct, is finely put in that.

10 . A huge crowd has gathered to watch China’s new scientific research ship enter the water for the first time. This ship, equipped with on-board labs and the latest scientific kit, will eventually explore the world’s oceans. But it is also going to help China plunge beneath the waves: it will serve as a launch-pad for submarines that can dive to the deepest parts of the ocean. “Humans know much less about the deep oceans than we know about the surface of the Moon and Mars. That’s why I want to develop the facility for ocean scientists to reach the deep seas,” says Prof. Cui Weicheng.

He is the dean of deep sea science at Shanghai Ocean University but he has also set up a private company called Rainbow Fish, which built the new research ship and is busy developing submersibles. One of its unmanned subs reached a depth of 4,000m (13,000ft) in its most recent trial. But Rainbow Fish’s ultimate goal is manned exploration and it plans to take humans to the very bottom of the ocean the Mariana Trench, in the Pacific, at a depth of nearly 11,000m (36,000ft). He shows me around a life-size model of the submarine and explains that there is room inside for a crew of three, who will be protected by a thick metal sphere.”At the moment, we are in the design stage, so we are testing several extremely high-strength materials for it.” It will have to bear immense pressures from the crushing weight of water above. If there are any weaknesses, the submarine will implode. The deepest ocean is a place few people have ever experienced first-hand. The first dive to the Mariana Trench was carried out in 1960 by US Navy Lieutenant Don Walsh and Swiss engineer Jacques Picard. Their vessel, the Bathyscaphe Trieste, creaked and groaned as it made the descent, taking nearly five hours.

The only other manned expedition was carried out by Hollywood director James Cameron, who took a solo plunge in a bright green submarine in 2012. Rainbow Fish wants its sub to be next. The team insists its venture isn’t about politics and that it is looking to collaborate with American, Russian and European scientists. It is, though, a commercial operation. The company plans to charge people to use its research ship and submarines, and is targeting three groups, says managing director Dr. Wu Xin. “The first is definitely the scientists who are interested in studying deep-sea science and technology. The second group is offshore companies and oil companies. The last one is tourists and adventurers [who] want to go down themselves to have a look at what’s going on there,” he says. This kind of entrepreneurial approach may be a new model for science in China. Deep-sea research is a difficult, high-risk activity — and much of the ocean remains unexplored. But Cui, who hopes to be the first Chinese person to reach the Mariana Trench, believes that China could be the nation to truly open up this final frontier.
