2 . It’s said that about one third of the world’s citizens live in substandard housing. But researchers have created free plans now available online for building houses using pre-made parts that fit together perfectly, which could help solve this housing problem.

The world population is expected to grow to more than 8 billion by 2030, and the housing situation in city is already a huge problem. Building new homes in the traditional way still takes weeks or months.

In a London neighborhood, a group of volunteers are constructing a house made of pre-made plywood panels (预制胶合板面板) and parts, the so-called WikiHouse. All parts were precisely cut in a Computer Numerical Control, or CNC machine, following a free plan downloaded from the Internet.

Founder of the UK-based on WikiHouse Foundation, architectural designer Alastair Parvin, said this could be the solution for affordable housing. WikiHouse is essentially a series of technologies we’re developing aimed at simplifying the process of making really sustainable high-performance houses to a point where almost anyone can do it.

Precise cutting allows a perfect fit for all parts, which speeds up the process of assembly (装配). No special tools are required. The WikiHouse was built in 10 days for exhibition purposes. Then, it was taken apart and reassembled elsewhere for permanent use.

“Open-source (开源)software is now really established; it drives a lot of the software we use,” Parvin said. “What's happening now is that that's coming into the world of physical things, so we're effectively building a kind of Wikipedia for physical material.”

Parvin said the project is in its early stages, with limited availability. But he said he expects it to grow as more people start showing interest in houses whose assembly requires no special skills.

On February 16, 1861, a big earthquake struck Sumatra, an Indonesian island. The earthquake shook the western side of the island,     1     ( cause) a tsunami(海啸). That wall of water poured onto shore, destroying towns and taking thousands of     2     ( life).

Recently, though, a team of scientists discovered that another earthquake     3     ( occur) before this deadly event. According to the record, that earthquake started in 1829 and lasted for 32 years but no one felt even one shake. This kind of slow-moving earthquake     4     (call) “silent earthquakes” because no instrument can find them. Scientists have only begun discovering them because     5     the advances in GPS technology in the last twenty years.

    6     (figure) out what is going on under the ground, scientists need to study earthquakes. Every earthquake, either small     7     big, can teach scientists something about how much the ground will shake in the future. Unluckily, no one can predict(预测) when an earthquake will hit. Scientists just have to prepare to study all earthquakes     8     strike.

But silent earthquakes like the one in Sumatra change the game for scientists. These silent earthquakes happen all over the world. Sometimes, a silent earthquake happens just before a regular one, both of which might be     9     (relate). By studying silent earthquakes, scientists hope to better understand regular earthquakes and     10     ( possible) predict them.

5 . The daily life can be busy and at times difficult.It may sometimes feel like bringing just a little more inner peace and calmness into your life is a hopeless wish.    1     Small and smart changes can make a big difference over time. Here are some tips for finding more peace and calmness in everyday life.

Set limits. If your life is overfilled,you may need to set some limits. So stop doing some of the least important things, which honestly don’t matter that much. Set a limit for how many times you will check your mailbox per day.     2    

Organise your world and your mind.     3     A tidy, clean and ordered space around you brings clarity (清晰) and order to the mind. So don’t stop there. Simplify and organise your home and life to live in a more relaxing environment.

    4     Reading minds is pretty much impossible. But still we often try it and create anxiety and uncertainty for ourselves. So ask and communicate instead. It may sometimes be a bit hard at first but it can save you and the people around you so much trouble in the long run.

Solve a problem that is weighing heavily on you. Settle your problem and release all the stress that it is creating in your life. You probably already know what to do, and you are just not doing it yet,     5     So get up from your chair and get started right now.

On March 21, an artist released a video     1     (title) “The Current Status of AI Utilization in Game Companies”, demonstrating the process of using AI in art. She said that her videos     2     (gain) only a few thousand views before. But this one swiftly got hundreds of thousands of views,     3     (cause) heated debate about the influence of AI on society.

AI painting,     4     involves coping human painting techniques, styles and thought processes via algorithms (算法) and models, enabling computers     5     (generate) artistic images, is a form of generative AI. The AI drawing software has achieved great popularity among users for its text-to-image method, which has     6     (dramatic) lowered the threshold (门槛) of artistic creation.

Despite the increased efficiency, people are becoming concerned about the possibility of losing their jobs. Not that long ago, painters     7     (think) to be immune to being replaced by AI. But now it appears     8     they are among the first professionals who might be out     9     a job because of the technology. For the time being, artists do not need to overly worry about being replaced by AI.     10     takes them years to perfect their ability to express their emotions, values and life experiences in unique ways, which is not attainable for AI-generated art at present.

8 . As my husband and I saw someone publicizing the benefits of spending time outdoors, we were lost in thought. Noticing my daughter had _________ a little homebody, we knew we had to _________ sport into our routine. We were determined to make skiing a family activity. But we needed our daughter’s _________.

The resort took account of almost all the trouble we might have in skiing. Of the fifty-three runs, eight were greens labeled with _________reading. “Route For Beginners”. However, when our instructor _________ us to ski，our hopes of being a __________skiing family were dashed (使破灭). “Ahh!” escaped our lips. She was __________ and said, “Sorry, I thought you were ready.” Then she went on to lead us down a gentler way. We still __________ many times. Everyone slid down the slope, but not without falls.

While the experience frightened us, it also __________ our dinnertime conversation. My daughter told us, “Although I had a hard time skiing, there is no __________ of happiness” I responded, “Your father and I enjoyed ourselves, too.” The next day, we __________ there as beginner skiers, but we believed we would be certainly expert skiers.
