4 . Over the years I’ve spent living in Beijing, I can _________ the number of truly outdoor experiences I’ve had on one hand. But a road trip to Nanshan Skiing Village in February 2021 provided me with some _________ memories.

As my friends and I sat together in the ski lift chair, I finally felt for the first time that I had _________ left the busy city life of Beijing. Up in the air a few dozen meters off the ground, I _________ the wide view of the countryside and appreciated the peaceful quiet.

As the ski lift reached its _________, I _________ slid off from the chair and almost did a face-plant into the snow. “So much for the peace and quiet”, I _________ to myself. _________, I gathered myself together and made my way as _________ as I could to one of the several starting points.

My buddies had already started making their way down the hill, and I was about to join them but suddenly fear __________ me as I noticed how easy it was to __________ speed. I __________ to swerve (突然转向) to the side to slow down, but ended up tumbling (摔倒) down into the snow.

Not wanting to become __________, I awkwardly reattached the ski. Although I still felt nervous, by accepting the risk I was able to ski more confidently and at last managed to make it down the whole ski slope (斜坡).

By the day’s end, I had relearned what it __________ to take risks and get out of my comfort zone. By accepting what seems __________, you can find both confidence and peace within.

5 . ‘Small Data’ Are Also Crucial for Machine Learning

Many people relate “artificial intelligence” with “big data.” There’s a reason for that: some of the most prominent AI breakthroughs in the past decade have relied on enormous data sets. Image _________ made great progress in the 2010s thanks to the development of ImageNet, a data set containing millions of images hand sorted into thousands of categories. More recently, GPT-3, a language model, was trained on _________ online texts to produce humanlike text in Jan, 2021. So it is not surprising to see AI being tightly connected with “big data” in the _________ imagination. But AI is not only about large data sets, and research in “small data” approaches has grown extensively over the past decade. The so-called transfer learning serves as an especially _________ example.

Also known as “fine-tuning,” transfer learning is helpful in settings where you have _________ data on the task of interest but abundant data on a related problem. You need to first train a model using a big data set and then retrain slightly using a smaller one related to your _________ problem. A research team working on German-language speech recognition, _________, showed that they could improve their results by starting with an English-language speech model trained on a larger data set. Then, they used transfer learning to _________ that model for a smaller data set of German-language audio.

Small data approaches such as transfer learning are more _________ than more data-intensive methods. They can promote progress in areas where little or no data exist, such as in forecasting natural hazards that occur relatively __________. In this context, small data approaches will become increasingly important as more organizations look to diversify AI application areas and invest in previously __________ fields.

Despite the progress in research, transfer learning has received relatively little __________. While many machine learning experts are likely familiar with it at this point, the existence of techniques such as transfer learning does not seem to have reached the awareness of the broader space of policymakers in positions of making important decisions about AI funding and __________.

As long as the success of small data technique like transfer learning is __________, resources can be allocated to support their widespread use. In that case, we can help correct the popular __________ regarding the role of data in AI and foster innovation in new directions.

Over the next few weeks,the training continued to be ____, but I never lost focus again. I lost twenty pounds, but ____ I was certificated as a firefighter. And now I can drive the big red trucks and serve my community. When most of my friends are retiring, I'm starting a new career I love. And I know that you're never too old to take on new_____; never too old to follow your dreams.

7 . The first thing I learned in folk dancing was apologies: “Sorry!” “Forgive me!” and “Did that hurt?”

I was deeply ashamed of seeing others _________ based on painful contact. Finally, the turning point came when I _________ a few of the most difficult dances and broke down barriers. Even the dancers who had thought little of my dance would _________ me out to lead dances. As I became _________ for my hard-won ability, I fell _________ to reach out to help others,__________ teaching and finding ways to __________ with those needing help. As a beginner, I had already made every possible mistake and __________ every rule, so I was well suited for the task. And that, in turn, helped me win __________

Keeping sharpening my dance skills, I was no longer a (n)__________ to those around me. But more importantly, by embracing a new experience, dance became a __________ for friendship I would never have imagined.

9 . Until April 2, 2011, everything in my life was perfect. I was sitting tight like every other ________ in the country to watch India ________ the world cup. But this day turned my ________ upside down.

I spent a year looking for ________ and approached various companies. To my luck in 2013, I got financial support from the Dakshin Rehabilitation Centre. Thereafter, I began taking my ________ in sports seriously and dreamt of representing India in Paralympics one day.
