China’s first large home-made cruise ship (游轮), roughly the height of a 25-story building, is 【小题1】(schedule) to be delivered to its user around the end of this year. Construction of the ship, which has yet to be named, started in October, 2019.

“So far, we have completed 90 percent of the cruise ship’s construction. Engineers have begun to install inner 【小题2】(equip). We plan to move it out of the dry dock in June 【小题3】(continue) the fitting process,” said Chen Gang, chief designer of the large cruise ship. After the construction finishes, there will be at least two sea trials in the summer to test the ship, and also to check 【小题4】 the rooms and entertainment facilities (设施) are comfortable. There will be 16 stories of living, shopping and entertainment space, which will offer a variety of musical 【小题5】(performance), art shows and food options.

“Upon its completion, there will be about 25 million components on the ship, 5 times that of China’s home-designed C919 plane and 13 times that on the Fuxing- series bullet train. The 【小题6】(combine) length of the electric cables on the ship is more than 4, 200 kilometers,” Chen said, 【小题7】(note) that his shipyard has used a lot of advanced techniques and machinery to build the ship.

The project marks the first time China has built a large advanced cruise ship 【小题8】 its own. It is a new milestone for the country’s shipbuilding industry because it marks an end to the time 【小题9】 China couldn’t design and construct large cruise ships 【小题10】(independent).

China’s new deep-sea manned submersible (潜水) Fendouzhe set a 【小题1】 (nation) diving record of 10,909 meters in the Mariana Trench. Only a few people 【小题2】 (visit) the bottom of the Mariana Trench so far.

Four hours after the task started, a group photo of three Chinese divers was sent back, with each one 【小题3】 (carry) a food plate in hand. They decided to work for six hours after they reached 【小题4】 deepest spot. That spot is known as the Challenger Deep, with a 【小题5】 (deep) of over 10,900 meters. The water pressure is 110 kPa, 【小题6】 makes designing and operating submersibles difficult.

The cabin covering uses titanium (钛), a perfect material with high strength that allows the submersible 【小题7】 (bear) water pressure at 10,000 meters under the sea. Powered by a battery, Fendouzhe can pick up samples (样本) from the surrounding environment 【小题8】 its flexible robotic arms, which can work with the accuracy of one centimeter.

Sylvia Earle, former chief scientist of the US NOAA, said that the world is 【小题9】 (current) in the greatest age of deep-sea research. China now is leading the world in many aspects of deep-sea 【小题10】 (explore).

In the age of the smart phone, there seems no reason to ask questions about: the weather forecast, a business’s phone number or directions, which can all be【小题1】 (easy) found on Google, but very often people actually ask these things by【小题2】 (make) a call. Your answer may be replied to with a thank-you e-mail.

This isn’t the first time that great changes 【小题3】 (take) place in our manners due to technology. In【小题4】late 1870s, when the telephone 【小题5】 (invent), people didn’t know how 【小题6】 (greet) a caller. Often there is just 【小题7】 (silent). Alexander Graham Bell, the inventor, suggested that people 【小题8】 (say) “Ahoy”, but finally “Hello” went out, the greeting used in everyday face-to-face communications now.

Try to be respectful no matter 【小题9】you communicate with. Just keep【小题10】mind that politeness never goes out of fashion.
