2. 只允许修改10处，多者（从第11处起）不计分。

When I was eight, my father bought me the new bike for my birthday. My brother offered to teach me how to ride. At first, they rode and let me watching. Then he explained me the skills of controlling the bike. Still puzzling, I got on the bike, but it doesn’t move as expected. I lost my balance and fall off the bike. At once I burst into tear because I saw blood on the ground. While I stood up, my left leg hurt bad. Later, I learned to ride a bike. But this experience told me that though some lessons were painful to learn them, yet we could benefit a lot.

7 . There’s an old saying that goes, “ Good fences make good neighbors. ” With so many people forced to stay at home during the pandemic, some are happy to report that good fences can also make good friends.

In Minneapolis, the Olson family lives next door to 99-year-old Mary O Neill. Although Mary has an adult daughter in the area who visits once a week, with the rest of her relatives scattered, the pandemic left the old woman in seclusion (与世隔绝).

But as lockdown went on, Mary managed to develop a special friendship with one of her neighbors — Benjamin Olson, aged 2. Over time, Mary watched through the fences as Benjamin learned to walk, talk and eventually run and play. Despite the huge differences in their ages, Benjamin noticed his elderly neighbor, delighting in her presence. Between the two, they developed a game they could play over the fence. Benjamin would pass her a ball and she’d hit it back to him with her cane.

While others might remark on the 97-year gap between the two pals, when Benjamin sees Mary, he simply sees a friend, not a number. Although the pair’s special affinity (亲和力) definitely scores high on the cuteness factor, Benjamin’s mum Sarah and Mary’s adult daughter believe the relationship has been a lifeline that’s kept the elderly woman going through the long period of isolation (隔离).

As pandemic restrictions have lifted, Mary and Benjamin’s friendship continues to blossom on both sides of the fence — only now, the gates can be opened.

“Friendship can just happen so many different ways, ” Sarah told CBS. “ I’m just really happy they were able to form this on — isolation or not, pandemic or not. I’m happy because it means a lot to her and it means a lot to him, too. ”
