21、A self-driving ship named after the Mayflower has been brought back while trying to re-create the cross-Atlantic trip made by the original Mayflower in 1620.
Last Tuesday, a robotic ship called the Mayflower Autonomous Ship (MAS) took off from Plymouth, England. Its mission was to re-create the 1620 crossing of the Atlantic by the Mayflower, which brought the first European settlers to what is now Plymouth, Massachusetts.
But unlike the original Mayflower, there are no people on the MAS. Everything about the ship is designed to run automatically. The ship is guided by an artificial intelligence (AI) system called “Al Captain”.
The MAS is a project run by a group called ProMare along with the computer company, IBM. The ship's electric motor is powered by solar energy. The goal of the project is to test different kinds of technologies for collecting information about the sea. If these can be handled by machines, it could be a big advance in ocean research. Sending humans to collect information at sea can be difficult, lonely, and dangerous.
In addition to cameras and radar to help the ship guide itself, the ship is carrying many different kinds of tools and sensors. It has special listening devices which can detect whales and dolphins. It even has a special “tongue” which can report back on the chemicals in the water.
Last Friday morning, scientists tracking the ship noticed that it was going about half as fast as it should have been going. The AI Captain was working well, but there seemed to be something slowing the motor down. Since the ship had only covered 10% of the way across the Atlantic, the team decided to bring it back to Plymouth so they could fix the problem and send it out again. They sent the MAS instructions to turn back.
When the MAS finally does put out to sea again, it is expected to take about three weeks to cross the Atlantic Ocean. The fastest speed for the MAS is about 10 mph (10 miles per hour). That may seem slow, but it's about 5 times faster than the original Mayflower, which took 66 days to make the journey.
【1】The aim of the MAS project is to ________.
A．take more Europeans across the Atlantic
B．experiment with technologies for sea exploration
C．develop new artificial intelligence system
D．test the AI Captain on the sea
【2】What happened to the MAS on the sea?
A．The robotic ship's electric motor didn't work well.
B．The scientists failed to guide the ship completely.
C．The AI Captain reduced the speed of the MAS.
D．There was something wrong with the AI Captain.
【3】What can we know from the last paragraph?
A．The entire cross-Atlantic journey will be about 2,100 miles.
B．The journey are likely to be difficult and dangerous.
C．The Mayflower Autonomous Ship has set sail again.
D．The original Mayflower travelled at about 2 mph at most.
【4】What's the best title for the text?
A．A Robotic Ship Guided by the AI Captain System
B．Self-driving Mayflower Ship Forced to Turn Back
C．The Fastest Robotic Ship Sailing Across the Atlantic
D．Another Mayflower Managing to Re-create the Cross-Atlantic Trip
22、No one in the US has 3D-printed a two-story house before. But now three companies are working together to print the first large, two-story house in the US.
The house, which is in Houston, Texas, was designed by a company. Another company provided the 3D printer. And a construction company is doing the actual building. Leslie Lok. who designed the house, says there are special challenges involved in printing the two-story house. One of the biggest is the size of the machine needed for the building. The 3D printer in Houston is massive. It weighs over 12 tons.
Ms. Lok says printing the house will take the massive machine about 330 hours. That’s about eight normal work weeks. But the team isn’t in a rush. Though it’s a two-year project, the actual printing didn’t start until last July. The house is now about halfway finished.
“We are not trying to beat the clock,” says Hikmat Zerbe, who works for the construction company. Instead, they’re using the house as a “big laboratory” to learn more about 3D-printing houses. They want to see how the concrete reacts “under different weather conditions”.
They also want to figure out how to make 3D-printing faster and cheaper. Mr. Zerbe says that currently, 3D-printing a house with concrete costs more than building a house with wood. That’s partly because the technology is new. With time, Mr. Zerbe expects the costs of 3D-printed houses to go down. He thinks printers will improve and make it easier to create more houses quickly. 3D-printed concrete houses are stronger and hold up better in serious storms than house built with wood. This can save money in the long run. Since the machine is doing the building, fewer workers are needed, which also saves money.
Besides, with 3D-printing, it’s easy to make each house different from other houses. These kinds of changes can apply to almost any tiling. Hikmat Zerbe says that means in the future, each house could be created specially for its owner.
【1】What is a big problem in printing the two-story house?
A．The limited time.
B．The lack of skilled workers.
C．The need for huge 3D printers.
D．The shortage of building materials.
【2】What is to be studied in the building process?
A．How the printed houses stand wear and tear.
B．How 3D-printed houses are made stronger.
C．How workers can print large houses quicker.
D．How concrete changes with the shift of weather.
【3】What is a disadvantage of the 3D-printed house at present?
A．Its cost is higher.
B．It can’t survive the storm.
C．It uses special concrete.
D．It needs experienced workers.
【4】How does Mr. Zerbe feel about the future of 3 D-printing?
A．Negative.
B．Unclear.
C．Worried.
D．Hopeful.
23、 When the natural climate changes due to global warming, it can surely affect seals (海豹). The majority of them live in the Antarctic region but the ice is melting and their natural habitat can be seriously affected. These changes don’t take place overnight. They can be the result of many years of additional temperatures in the area. The seals then have to find ways to adapt.
Seals depend on the cool air currents to bring plenty of food for them. When the temperatures get higher there is less and less food and the seal population starts to get depleted. Mothers are not healthy enough to feed their babies. Many of them end up abandoned as the mothers have to leave to find their own source of food.
The fact that their desire to produce young can be changed and the warmer temperature is frightening too. It is also believed that the warmer temperature can allow different diseases and viruses to attack the seals. This is a huge concern as they can rapidly wipe out huge numbers of seals out there.
However, these changes in climate and temperature aren’t all bad for other species of seals. Scientists have found that those living in warmer climates are producing more young due to the changes. Research also shows that the females are moving further to find food and water. When they are out of the reach of the governing males, they are more willing to accept the moves of other males in the group.
This is good news too because it means that there will be more selection in the gene pool (基因库) for future generations. It can help the seals as a species adapt to change in their natural environment more easily.
The climate change problem for seals is directly linked to humans. When we take action to change what we let out into the environment, we will make positive changes for the seals. However, it is going to take a very long time to reverse (彻底改变) the effects of what has already been done.
【1】What does the author regard climate changes for seals as?
A.A mirror of evolution.
B.A double-edged sword.
C.An unavoidable disaster for existence.
D.A requirement for more choice in the gene pool.
【2】What does the underlined phrase in paragraph 2 probably mean?
A.Explode. B.Vary.
C.Disappear. D.Decrease.
【3】What will happen to the seals in warmer climates?
A.The female seals will be in the lead.
B.Their genes will change a great deal.
C.Their number will be on the increase.
D.The females will keep away from the males.
【4】What’s the main idea of the text?
A.How climate change affects seals. B.The importance of protecting seals.
C.Seal’s adaptation to climate change. D.Why seals are becoming less and less.
